A VPN (Virtual Private Network) creates an encrypted tunnel between your device and a remote server, hiding your internet traffic from your ISP and masking your IP address from websites you visit. In 2026, the best VPN services for most users are NordVPN for speed and all-round capability, Mullvad for maximum privacy, ProtonVPN for the strongest combination of transparency and performance, Surfshark for budget-conscious households, and ExpressVPN for polished usability with caveats about its corporate ownership. This guide compares these five services in depth - plus five additional providers - on the criteria that actually matter: jurisdiction, audit results, real-world legal tests, protocol quality, and honest assessment of what VPNs can and cannot protect against.

The VPN market is simultaneously one of the most useful and most misleading sectors in consumer technology. Useful, because a well-chosen VPN genuinely protects your privacy on untrusted networks, prevents your ISP from selling your browsing history, and allows access to geo-restricted content. Misleading, because the industry is saturated with marketing claims - "military-grade encryption," "truly anonymous," "no logs guaranteed" - that range from misleading to technically meaningless. A VPN provider can claim zero logs and simultaneously be owned by a holding company with a history of distributing adware. The marketing and the reality are not always the same document.

Evaluating a VPN in 2026 requires looking past the marketing. The meaningful questions are: Does the provider operate under a jurisdiction that respects privacy? Has it undergone independent third-party audits with published results? Has it ever received a legal order and what happened when it did? What protocol does it use and how does that protocol perform? What does the privacy policy actually say, in plain language? Is the company independently owned or part of a holding company with a troubling acquisition history?

"Arguing that you don't care about the right to privacy because you have nothing to hide is no different than saying you don't care about free speech because you have nothing to say." - Edward Snowden, 2015

Key Definitions

VPN (Virtual Private Network): A technology that creates an encrypted tunnel between your device and a VPN server, routing your internet traffic through that server so that your ISP and local network see only the VPN connection, and websites see the VPN server's IP address rather than yours.

No-log policy: A commitment by a VPN provider not to retain records of user activity, connection timestamps, IP addresses, or session data. The value of this claim depends entirely on independent verification - marketing claims without published audit evidence are not verification.

Kill switch: A feature that cuts all internet connectivity if the VPN connection drops unexpectedly, preventing traffic from leaking outside the encrypted tunnel and exposing your real IP address. A VPN without a reliable kill switch provides intermittent protection at best.

DNS leak: A situation where DNS queries (the translations of domain names like "google.com" to IP addresses) bypass the VPN tunnel and are handled by your ISP's DNS servers, revealing which domains you visit even while using a VPN. Reliable VPNs handle DNS resolution within the tunnel.

WireGuard: A modern VPN protocol merged into the Linux kernel in March 2020 by creator Jason Donenfeld. It is significantly faster than OpenVPN, has a dramatically smaller codebase (approximately 4,000 lines versus 70,000+ for OpenVPN), and is easier to audit for security vulnerabilities. WireGuard has become the baseline protocol for modern VPN performance.

Jurisdiction: The legal country in which a VPN provider is incorporated. Providers outside intelligence-sharing alliances (Five Eyes: US, UK, Canada, Australia, New Zealand; Nine Eyes: adds Denmark, France, Netherlands, Norway; Fourteen Eyes: adds Germany, Belgium, Italy, Spain, Sweden) and without mandatory data retention laws face less legal pressure to log or disclose user data.

RAM-only servers: Servers that run entirely from volatile memory rather than writing to persistent disks. Any data in server memory is irretrievably lost when the server is powered down, providing meaningful protection against physical server seizure.

How VPNs Actually Work: The Technical Foundation

Understanding the technical mechanism helps you make a better-informed choice between providers and, more importantly, understand what a VPN can and cannot protect.

When you connect to a VPN, your device and the VPN server perform a cryptographic handshake using asymmetric encryption (typically RSA-2048 or ECDH key exchange via Curve25519) to establish a shared session key. All subsequent traffic is encrypted symmetrically using that session key, typically with AES-256-GCM or ChaCha20-Poly1305 - both considered secure against all known attacks, including theoretical quantum computing attacks at current capability levels.

Your device sends all traffic to the VPN server inside the encrypted tunnel. The VPN server decrypts it, forwards your original requests to the internet using its own IP address, receives the responses, re-encrypts them, and sends them back through the tunnel.

From your ISP's perspective, it sees an encrypted connection to one IP address (the VPN server) and nothing else - no domains visited, no content accessed, no unencrypted metadata. From the websites you visit, they see the VPN server's IP address and location. This is the core protection a VPN provides.

The Protocol That Changed Everything: WireGuard

Before WireGuard, the dominant VPN protocol was OpenVPN, a robust but aging protocol with a codebase exceeding 70,000 lines of code. OpenVPN works, but its size makes comprehensive security auditing difficult, its connection establishment is slow (particularly on mobile networks), and its throughput on modern high-speed connections is limited by its design.

WireGuard, created by Jason Donenfeld and merged into the Linux kernel in March 2020, changed the landscape. At approximately 4,000 lines of code, it is small enough for a single security researcher to audit thoroughly. Its connection establishment is nearly instantaneous - critical for mobile users whose devices constantly switch between Wi-Fi and cellular networks. And its throughput is significantly higher than OpenVPN, typically retaining 80 to 90 percent of base connection speed on nearby servers versus 50 to 70 percent for OpenVPN.

Most major VPN providers now use WireGuard or WireGuard-derived protocols as their default: NordVPN's NordLynx, Surfshark's native WireGuard implementation, ProtonVPN's WireGuard option, and Mullvad's WireGuard default. ExpressVPN uses Lightway, a proprietary protocol built on wolfSSL that achieves comparable performance to WireGuard and has been independently audited by Cure53.

What VPNs Cannot Protect Against

Understanding the limits of VPN protection is as important as understanding its benefits. No amount of privacy tooling compensates for misunderstanding the threat model:

  • Logged-in account activity: If you visit Facebook, Google, or Amazon while logged in, those services know it is you regardless of your IP address. A VPN does not provide anonymity from services you authenticate to.
  • Browser fingerprinting: Your browser's unique combination of screen resolution, installed fonts, plugins, timezone, language settings, and hardware characteristics can identify you across sessions without cookies or IP matching. The EFF's Panopticlick study (now Cover Your Tracks) found that 83.6 percent of browsers had a unique fingerprint.
  • Traffic analysis at scale: Nation-state actors with visibility into both ends of a connection (your ISP and the destination server) can sometimes correlate timing patterns to identify users even with encrypted VPN traffic. This is a realistic threat for journalists and activists in authoritarian states.
  • Malware on your device: A VPN encrypts traffic in transit but does not protect against keyloggers, spyware, or other local compromises. A compromised device leaks data regardless of the VPN.
  • The VPN provider itself: The provider can see your traffic metadata and, depending on its architecture, your activity. The entire model depends on trusting your VPN provider more than you trust your ISP. This is why audits and real-world legal tests matter.

NordVPN: Best All-Round Speed and Features

NordVPN is the most recognized consumer VPN brand globally and consistently among the top-rated services in independent speed tests. Operated by Nord Security (registered in Panama, with offices in Lithuania), it serves an estimated 14 million users worldwide as of 2025. Its reputation was damaged by a 2018 server breach (disclosed in 2019) but it has largely recovered through remediation, expanded auditing, and a transparency report program.

NordLynx Performance

NordVPN's WireGuard implementation, branded NordLynx, delivers consistently fast speeds. NordLynx wraps WireGuard in a double NAT system that addresses WireGuard's original privacy limitation (WireGuard by default requires storing user IP addresses on the server). In 2025 independent testing by Tom's Guide and PCMag, NordVPN retained an average of 78 to 85 percent of base connection speeds on nearby servers - better than most competitors. Long-distance connections (US to Asia) retained around 40 to 50 percent, which is competitive with the best in the market.

For comparison, a user with a 500 Mbps base connection would typically see 390 to 425 Mbps through NordLynx on a nearby server - fast enough that the VPN is invisible for all practical purposes including 4K streaming, large file transfers, and video conferencing.

Audit Track Record

NordVPN has been audited by PricewaterhouseCoopers (twice, in 2018 and 2020) and Deloitte (2022), covering its no-log policy and server infrastructure. Results are published and available for review. The audits confirmed that NordVPN's infrastructure does not retain user activity logs, connection timestamps, or traffic data.

The 2018 breach - which affected a single rented server in Finland through a vulnerability in the data center provider's remote management system, not in NordVPN's own software - led to an overhaul of NordVPN's server infrastructure. The company transitioned to colocated, owned hardware in its most sensitive locations and deployed RAM-only server architecture across its network, reducing third-party risk.

Specialty Servers

NordVPN offers several specialty server types that serve specific threat models:

  • Onion over VPN: Routes traffic through Tor after the VPN, providing the anonymity of Tor with the ISP-hiding of a VPN
  • Obfuscated servers: Disguise VPN traffic as regular HTTPS for use in restrictive countries like China, Iran, and Russia where VPN traffic is blocked
  • Double VPN: Chains traffic through two VPN nodes in different countries, so that even if one node is compromised, the attacker only sees the other VPN node, not the user
  • Dedicated IP: A static IP address assigned only to you, useful for accessing services that whitelist specific IPs

Best for: General consumers wanting the best balance of speed, features, and verified privacy. Strong for streaming (reliably unblocks Netflix, Disney+, BBC iPlayer, and most major platforms) and everyday use. The 10-device limit is sufficient for most individuals.

ExpressVPN: Polished UX with an Ownership Question

ExpressVPN was the leading premium VPN for many years, known for polished interface design, consistent performance across geographies, and strong geo-unblocking capability for streaming services. In September 2021, it was acquired by Kape Technologies for approximately $936 million - a transaction that fundamentally changed how the privacy community evaluates the service.

The Kape Technologies Concern

Kape Technologies (LSE: KAPE) is a holding company that also owns Private Internet Access, CyberGhost, and ZenMate. Kape's predecessor company, Crossrider, was known for distributing adware and browser extensions that hijacked user settings - activities that are diametrically opposed to the privacy mission of a VPN provider.

While Kape has reportedly restructured since rebranding in 2018, and ExpressVPN states that it operates independently under its existing management team, the ownership history creates a conflict of interest that privacy-conscious users consider relevant. A 2022 investigation by Restore Privacy detailed the corporate history and raised questions about whether a company with roots in ad-tech surveillance should be trusted with users' internet traffic.

ExpressVPN's independent audits by KPMG (2022) and Cure53 (multiple engagements covering both the Lightway protocol and server infrastructure) are genuine positive signals. But the ownership context remains a legitimate consideration, particularly for users whose threat model extends beyond casual privacy.

Lightway Protocol

ExpressVPN's proprietary protocol, Lightway, is built on wolfSSL and is comparable in speed to WireGuard. Unlike NordLynx, Lightway's source code is fully open-source (available on GitHub) and has been independently audited by Cure53. Performance is strong, particularly on mobile where reconnection after network changes is fast - Lightway can re-establish a connection in under 200 milliseconds compared to several seconds for OpenVPN.

Best for: Users who prioritize polished UX and reliable streaming access and are comfortable with the ownership context. ExpressVPN's apps are the most intuitive in the market, making it a good choice for non-technical users. The Kape affiliation makes it a secondary recommendation behind NordVPN, Mullvad, and ProtonVPN for strictly privacy-first users.

Mullvad VPN: The Privacy Standard

Mullvad is the privacy purist's choice and holds a unique position in the VPN market for the depth of its commitment to anonymity. Founded in 2009 in Gothenburg, Sweden, by Fredrik Stromberg and Daniel Berntsson, Mullvad does not require an account email address, accepts cash and cryptocurrency payment, has survived a police raid without producing user data, and publishes detailed audit reports. If your threat model requires the highest available privacy protection, Mullvad is the standard against which all others are measured.

The Anonymous Account Model

Mullvad assigns each user a random 16-digit account number. No personal information is associated with this number. No email address is collected. No name, no phone number, no payment details linked to identity.

You can pay by mailing cash in an envelope to Mullvad's office in Sweden. You can also pay with Bitcoin, Bitcoin Cash, or Monero. The practical consequence is that even if Mullvad's systems were breached, there is no database linking account numbers to real identities. This is a fundamentally different privacy architecture than providers that require email registration and credit card payment.

The 2023 Police Raid

In April 2023, Swedish police executed a search warrant at Mullvad's Gothenburg offices, intending to seize servers and customer data as part of an investigation. Mullvad's response, detailed in a public statement, was that police left empty-handed because there was genuinely no customer data to seize. The company's no-log architecture meant that even with physical access to the infrastructure, there was nothing to find.

This is the gold standard of no-log verification: a real-world legal test with a documented outcome. Marketing claims are one thing. Surviving a police raid is another. No other major VPN provider has been tested this definitively.

RAM-Only Infrastructure

Mullvad's servers run entirely from RAM rather than writing to persistent disks. Any data in server memory is irretrievably lost when a server is powered down, providing meaningful protection against physical server seizure - exactly the scenario that played out in the 2023 raid. Mullvad also publishes its server list with exact locations and ownership status, providing transparency about its infrastructure that most providers do not match.

Flat Pricing Philosophy

Mullvad charges a flat 5 euros per month with no multi-year discount. This is intentional: no marketing incentive to lock users into long-term commitments, no dark patterns around auto-renewal, no confusing tier structure. You pay month-to-month at the same rate regardless of tenure. In a market where deceptive pricing practices are common, Mullvad's straightforward pricing is itself a signal of the company's values.

Best for: Privacy-first users who want no personal data associated with their VPN account. Journalists, activists, whistleblowers, and anyone with a serious privacy threat model. Not optimized for streaming (smaller server network than competitors, and Mullvad does not actively work to unblock streaming services).

ProtonVPN: Best Combination of Privacy and Transparency

ProtonVPN is operated by Proton AG, the Swiss company behind ProtonMail, Proton Drive, and Proton Calendar. Founded in 2014 by scientists from CERN (the European Organization for Nuclear Research), Proton's privacy credentials are reinforced by Swiss jurisdiction (outside EU and US intelligence networks), open-source clients with published audit results, and the company's documented history of resisting legal orders in ProtonMail cases.

The Swiss Advantage

Switzerland is not a member of the European Union and is not party to the Five Eyes, Nine Eyes, or Fourteen Eyes intelligence-sharing agreements. Swiss privacy law is among the strongest in the world. While Swiss authorities can compel Swiss companies to provide data under certain conditions, the legal threshold is high and the process involves judicial oversight. Proton has published transparency reports documenting legal orders received and its responses, providing a level of accountability that most VPN providers do not offer.

Free Tier: The Best in the Market

ProtonVPN offers a genuinely usable free tier with no data limits, no speed throttling in absolute terms (free users share a lower-priority network during peak hours), and no advertising. This is unusual in a market where most free VPNs are either data-limited (TunnelBear's 2GB/month), severely speed-limited, or monetize user data. The free tier covers servers in 3 countries (US, Netherlands, Japan) and 1 simultaneous device.

The free tier serves a dual purpose: it provides genuine privacy protection to users who cannot afford a paid VPN (including activists and journalists in countries where VPN use is critical for safety), and it introduces users to Proton's ecosystem with the expectation that some will upgrade to paid plans over time.

Secure Core Architecture

ProtonVPN's Secure Core feature routes traffic through hardened servers in Switzerland, Iceland, or Sweden before exiting through a standard VPN server in the target country. An attacker who compromises the exit server (or who monitors traffic at the exit point) sees only traffic from a Swiss or Icelandic relay node, not the user's real IP.

This provides meaningful protection against a specific threat: compromised exit nodes. In standard VPN architecture, the exit server is a single point of failure - if it is compromised or monitored, user traffic is exposed. Secure Core adds a layer of indirection that mirrors the design philosophy of systems that account for component failure.

Open Source and Audited

ProtonVPN's clients for all platforms (Windows, macOS, Linux, Android, iOS) are fully open source and available on GitHub with active maintenance. Third-party security audits have been conducted by SEC Consult and Securitum, with results published. This combination of open-source code and independent audits offers a level of verifiable transparency that few competitors match - anyone with security expertise can review the code and confirm that the clients behave as described.

Best for: Users who want the strongest combination of verified privacy, reliable performance, and organizational transparency. The free tier is the best in class for occasional or cost-constrained use. The Secure Core feature is valuable for users in high-risk environments.

Surfshark: Best Value for Households

Surfshark is notable for offering unlimited simultaneous device connections on all plans - a meaningful differentiator for families or users with many devices. Founded in 2018 and based in the Netherlands, it was acquired by Nord Security (NordVPN's parent company) in February 2022, creating a combined entity controlling two of the top consumer VPN brands. Surfshark states that it continues to operate independently under separate management and infrastructure.

CleanWeb and Nexus

CleanWeb is Surfshark's ad, tracker, and malware blocking feature, integrated at the VPN level. By filtering threats at the DNS level within the VPN tunnel, CleanWeb blocks ads and trackers before they reach your browser, reducing page load times and data consumption - particularly noticeable on mobile.

Nexus is a proprietary IP rotation technology that allows more granular control over how traffic is routed between Surfshark's server network. In practical terms, it reduces IP address reuse (which can trigger streaming service blocks and CAPTCHAs) and can improve connection stability for users who maintain persistent VPN connections.

Value Proposition

At approximately $2.19 per month on a two-year plan, Surfshark is one of the most affordable premium VPN options available. Combined with unlimited devices, it offers strong value for households or users managing many connected devices - laptops, phones, tablets, smart TVs, routers. Its audit history (Cure53 for browser extensions, Deloitte for no-log policy in 2022) is solid.

A 2024 survey by Security.org found that the average U.S. household has 17 connected devices. At providers charging per-device or capping at 5-6 simultaneous connections, covering a full household requires either multiple subscriptions or router-level VPN configuration. Surfshark's unlimited device policy eliminates this friction.

Best for: Households, families, or users with many devices who want solid privacy protection at the lowest per-device cost. The Nord Security ownership is worth noting for privacy purists but has not compromised the service's audit track record or operational independence.

Additional Services at a Glance

Provider Key Strength Price (Approx.) Ownership Status Notable Limitation
Private Internet Access (PIA) Open-source clients; no-log proven in US court (2016, 2018) ~$2.03/mo (3-yr) Kape Technologies Kape ownership concerns
CyberGhost Largest server count (9,500+); streaming-optimized profiles ~$2.03/mo (2-yr) Kape Technologies Kape ownership; less independent audit depth
Windscribe Generous free tier (10GB/mo); R.O.B.E.R.T. DNS filtering $5.75/mo or $69/yr Independent, Canadian Five Eyes jurisdiction
IVPN No account email; privacy-focused; WireGuard $6/mo or $60/yr Independent, Gibraltar Small server network
TunnelBear Annual security audits (Cure53); most beginner-friendly UX $3.33/mo (1-yr) McAfee (subsidiary) Small free tier (2GB); corporate parent

Private Internet Access: Court-Tested No-Log

PIA holds a distinction that only Mullvad can match: its no-log policy has been tested in actual legal proceedings. In both 2016 and 2018, the FBI subpoenaed PIA for user data in criminal investigations, and PIA demonstrated that it had no data to provide. Court documents confirm this. The Kape ownership creates tension with these privacy credentials, but the historical legal record is genuine.

IVPN: The Other Privacy Purist

IVPN, registered in Gibraltar and operated by a small independent team, shares Mullvad's philosophy: no email required for account creation, no personal data collected, flat transparent pricing, and a focus on privacy over feature count. For users who want Mullvad-level privacy with a slightly different server network geography, IVPN is a strong alternative.

Use Case Recommendations

Maximum Privacy, Minimum Data Trail

Choose Mullvad. No email required, cash payment accepted, RAM-only servers, police-raid-verified no-log policy. The privacy ceiling is the highest of any major provider. Supplement with the Tor Browser for activities requiring anonymity beyond IP masking.

Best All-Round Privacy and Performance

Choose ProtonVPN. Swiss jurisdiction, open-source clients, audited no-log policy, Secure Core architecture, and the best free tier in the market. The strongest combination of verified privacy and reliable performance for most users.

Fastest Speeds for Streaming and Everyday Use

Choose NordVPN. NordLynx delivers consistently the best speed-retention scores in independent tests. NordVPN's obfuscated servers add flexibility for travel to restrictive countries. Reliable geo-unblocking for Netflix (multiple regions), Disney+, BBC iPlayer, Amazon Prime Video, and most major streaming platforms.

Budget-Conscious with Many Devices

Choose Surfshark. Unlimited simultaneous connections, two-year pricing under $2.50 per month, and a solid audit record make it the strongest value option for households and families.

Privacy Purist Outside Kape Ecosystem

Choose IVPN or Mullvad. Both are independently operated, require no personal account data, and are completely outside the Kape Technologies ownership umbrella that covers ExpressVPN, CyberGhost, and PIA.

Business or Remote Work Use

Choose NordVPN Teams or ProtonVPN for Business. Both offer team management features, centralized billing, dedicated IP options useful for accessing corporate resources through IP whitelisting, and admin controls for enforcing VPN usage policies across distributed teams.

Occasional Free Use

Choose ProtonVPN free tier (no data cap, no ads) or Windscribe (10GB per month, expandable to unlimited free through promotional tasks). Both are genuinely usable without a subscription and do not monetize user data.

What to Look for When Evaluating Any VPN

Beyond the services covered here, these are the criteria that matter most when evaluating any VPN provider. Apply these as a framework for systematic evaluation rather than relying on marketing claims or affiliate-driven review sites:

  1. Independent audit results: Published, from a named firm, covering both the no-log policy and the server infrastructure. Marketing claims without audit evidence are not verification. Ask: can I read the audit report?
  2. Jurisdiction: Outside the Fourteen Eyes alliance and without mandatory data retention laws. Panama, Switzerland, Iceland, British Virgin Islands, and Gibraltar are consistently cited as favorable jurisdictions.
  3. Ownership transparency: Is the company independently operated or part of a holding company? Who owns the holding company? What is their history? A VPN owned by an advertising company has a structural conflict of interest regardless of current behavior.
  4. Real-world legal tests: Has the provider received subpoenas, warrants, or legal orders? What happened? No-log policies that have survived legal challenges (Mullvad, PIA) are more credible than those that have never been tested.
  5. Open-source clients: Verifiable code is more trustworthy than black-box applications. Look for clients published on GitHub with recent maintenance activity and independent audit history.
  6. Protocol quality: WireGuard is now the baseline for modern VPN performance. OpenVPN remains a valid fallback for compatibility. Proprietary protocols should be fully open-sourced and audited to be trusted.
  7. Business model clarity: How does the provider make money? Subscription revenue is the healthy model. If a VPN is free and the business model is not transparent, you may be the product.

The Broader Context: VPNs in the Privacy Landscape

A VPN is one tool in a broader privacy toolkit, not a complete solution. For users whose threat model extends beyond hiding traffic from their ISP, a VPN should be combined with:

  • A privacy-focused browser (Firefox with strict settings, or Brave) to reduce fingerprinting
  • A DNS resolver that does not log queries (Quad9, Cloudflare 1.1.1.1, or the VPN provider's own DNS)
  • HTTPS-only mode in your browser to ensure end-to-end encryption even if the VPN tunnel were compromised
  • Compartmentalized browsing: Use different browsers or profiles for different activities to prevent cross-site tracking
  • Awareness of what a VPN does not protect against: Logged-in accounts, browser fingerprinting, local malware, and the VPN provider itself

The Electronic Frontier Foundation's Surveillance Self-Defense guide provides a comprehensive, regularly updated resource for understanding the full privacy landscape and choosing appropriate tools for different threat models.

For most users, a reputable VPN combined with sensible browsing habits provides meaningful privacy improvement over an unprotected connection. The key is choosing a provider whose claims are backed by evidence rather than marketing, and understanding the boundaries of the protection offered.

Frequently Asked Questions

Which VPN has the best privacy in 2026?

Mullvad has the strongest verified privacy: no account email required, cash payment accepted, RAM-only servers, and in 2023 Swedish police raided their offices and left with nothing because no user data existed. ProtonVPN is the best all-round option combining Swiss jurisdiction, open-source audited clients, and a usable free tier.

Does a VPN make you anonymous online?

No. A VPN hides your IP address and encrypts traffic from your ISP, but it does not prevent tracking via logged-in accounts, browser fingerprinting, or cookies. The VPN provider itself can see your traffic. True anonymity requires layered tools beyond a VPN.

Is Mullvad VPN really no-log?

Yes, with real-world verification. In 2023 Swedish police raided Mullvad seeking customer data and left empty-handed because no logs existed. Mullvad also requires no email address and offers cash payment, meaning even a breach would yield no personal data.

Should I avoid VPNs owned by Kape Technologies?

Kape Technologies owns ExpressVPN, CyberGhost, and Private Internet Access. Kape's predecessor (Crossrider) had an adware history. All three services have published independent audits and no evidence of current misconduct, but privacy-focused users reasonably prefer independently operated alternatives like Mullvad, ProtonVPN, or IVPN.

What is WireGuard and why does it matter for VPN speed?

WireGuard is a modern VPN protocol merged into the Linux kernel in 2020 with roughly 4,000 lines of code versus 70,000+ for OpenVPN. It connects faster, drops less, and retains more of your base connection speed. Most major VPNs now use it: NordVPN calls it NordLynx, Mullvad uses it by default, Surfshark and ProtonVPN both support it natively.
