Every VPN says it's private. Every VPN says "no logs." It's on every landing page, every ad, every affiliate review site.
But after spending weeks going through court filings, FTC complaints, app tracker audits, and corporate ownership records, I can tell you: most of those claims range from misleading to outright false.
This isn't a speed test roundup. This is a guide to the seven things that actually determine whether a VPN protects your privacy — written so you can check them yourself, even if you've never touched a terminal.
Who actually owns it?
Why it matters: If the company behind your VPN has a history of selling data, ties to intelligence agencies, or has gone private to avoid public scrutiny — none of the technical features matter. The people running the show determine what happens to your data.
What to look for: Google the parent company. Check if it's publicly traded (financial disclosures are public) or privately held (they can hide almost everything). Look for acquisitions, mergers, and name changes — companies rebrand to escape bad press.
The cautionary tale: Kape Technologies owns ExpressVPN, CyberGhost, Private Internet Access, and ZenMate. Before it was "Kape," it was called Crossrider — a company that made money injecting ads and browser extensions into user traffic. Security vendors flagged their software as adware.
It gets worse. ExpressVPN's former Chief Information Officer, Daniel Gericke, was fined $335,000 by the U.S. Department of Justice for his role in Project Raven — a UAE-backed cyber espionage operation that targeted journalists and human rights activists. ExpressVPN defended his employment.
In 2023, Kape's majority owner took the company private, delisting it from the London Stock Exchange. That means no more public financial disclosures, no more regulatory filings, no more transparency. The company that controls ExpressVPN, CyberGhost, and PIA is now a corporate black box.
Oh, and Kape also owns vpnMentor — one of the most popular VPN review sites. So the company that builds the VPNs also owns the site that reviews them.
The quick check: Search "[VPN name] parent company" and "[parent company] controversy." If the results make you uncomfortable, trust that instinct.
The other monopoly: NordVPN, Surfshark, and Tesonet
Kape gets most of the attention, but there's a second consolidation story that flies under the radar.
NordVPN and Surfshark — two of the most popular VPNs in the world — merged in February 2022. They still market themselves as separate, competing products. They still show up as independent options on review sites. But they're the same company: Nord Security.
That's not the uncomfortable part. The uncomfortable part is where they both came from.
Both NordVPN and Surfshark were incubated by Tesonet, a Lithuanian tech conglomerate based in Vilnius. Surfshark's CEO confirmed this publicly in 2022 to Lithuanian business press. NordVPN's connection to Tesonet has been documented since 2018, when security researchers traced shared infrastructure, overlapping corporate officers, and code-signing certificates back to the same entity.
Why Tesonet matters: Tesonet also operates Oxylabs — one of the largest residential proxy networks in the world. Oxylabs sells access to millions of real people's IP addresses for web scraping, data mining, and ad verification. A jury ordered Oxylabs to pay $7.5 million in a lawsuit over its proxy practices.
To be clear: a company that runs a data mining and residential proxy business also incubated two of the world's most popular "privacy" VPNs. NordVPN has denied any operational connection between its VPN service and Tesonet's data mining activities. But the corporate lineage is documented, and the same people appear across both entities.
NordVPN's other issues:
The 2018 server breach. In October 2019, NordVPN confirmed that one of its rented servers in Finland had been compromised in March 2018. An attacker exploited an insecure remote management system installed by the data center provider — without NordVPN's knowledge — and obtained expired TLS private keys and server configuration files. NordVPN didn't disclose the breach for over a year and a half, only confirming it after a security researcher posted evidence on Twitter.
The marketing machine. NordVPN runs one of the largest influencer marketing operations in tech. Sponsored YouTube videos featuring NordVPN have accumulated over 4 billion views. The UK's Advertising Standards Authority called out NordVPN for misleading claims about Wi-Fi security. When a VPN spends more on marketing than most VPNs spend on infrastructure, ask yourself what's actually being sold.
Closed source. Despite all the audit talk, NordVPN's client apps are not open source. You can't inspect the code. You can't verify what the app does on your device. You're trusting the binary — from a company incubated by a data mining conglomerate.
Surfshark's issues are similar. Same Tesonet origin. Same merger with Nord Security. Closed-source app with 42 Android permissions and 3 embedded trackers. Based in the Netherlands — a 14-Eyes member. And in April 2026, Surfshark's transparency report disclosed that it complied with a warrant from the Amsterdam District Court, confirming an account's existence and handing over payment information.
NordVPN and Surfshark both work fine as VPNs. They're fast, they unblock streaming services, and NordVPN has six Deloitte audits confirming no traffic logs. But if your reason for using a VPN is privacy — not Netflix — the Tesonet connection, the closed-source apps, the tracker-laden Android clients, and the merger that created another VPN monopoly should factor into your decision.
The pattern: Kape owns ExpressVPN, CyberGhost, PIA, and ZenMate. Nord Security owns NordVPN and Surfshark. Between these two companies, a huge share of the global VPN market is controlled by just two corporate entities — both with histories that should make privacy-focused users uncomfortable. The "competition" you see on review sites is largely an illusion.
Has "no logs" been proven — in court or under raid?
Why it matters: Every VPN's website says "zero logs." It's the most overused, least verified claim in the industry. The only way to know if it's true is when someone actually tries to get the data — law enforcement, a court order, or a physical raid — and comes up empty.
What "no logs" should mean: The VPN doesn't store your IP address, the sites you visit, connection timestamps, bandwidth usage, or DNS queries. Not "we store it but delete it after 30 days." Not "we anonymize it." Zero. Nothing.
The gold standard — OVPN in court: In 2020, film companies sued OVPN in Stockholm, demanding they hand over the identity of a user behind a specific IP address at a specific time. OVPN didn't just say "we don't have it." They proved to the court that their servers run entirely in RAM with no hard drives — making it physically impossible to store or retrieve that data. The court ruled in OVPN's favor and ordered the film companies to pay OVPN's legal fees.
That's not a marketing claim. That's a judge saying: "This company literally cannot comply because the data doesn't exist."
The gold standard — Mullvad under raid: In April 2023, Swedish police raided Mullvad's headquarters in Gothenburg with a warrant to seize computers and extract customer data. The police left empty-handed. Mullvad's servers had no disks. Their accounts have no email addresses. There was nothing to take.
The quick check: Search "[VPN name] court case" or "[VPN name] police raid" or "[VPN name] subpoena." If the company has been tested and produced nothing, that's real proof. If the only evidence is their own blog post saying "we don't log," that's marketing.
Does it run on RAM-only servers?
Why it matters: Traditional servers use hard drives. Hard drives keep data even when the power is off. If someone seizes a traditional server — law enforcement, a hacker, a rogue data center employee — they can potentially recover logs, encryption keys, and session data using forensic tools.
RAM (the temporary memory your computer uses while it's running) loses everything the instant power is cut. A VPN running entirely in RAM physically cannot retain data between reboots. Pull the plug, and everything is gone. Not deleted — gone. The physics of volatile memory guarantee it.
What to look for:
- Mullvad completed a full migration to RAM-only (diskless) servers in September 2023. They use a system called "stboot" with a hardware chip (TPM) that cryptographically verifies the operating system hasn't been tampered with before it boots. The entire OS weighs about 200MB and runs from memory. No disks anywhere in the network.
- OVPN owns 100% of their bare-metal servers — no rented hardware. Each server boots via iPXE, downloads an encrypted OS image, verifies its cryptographic signature, and loads into RAM. If the signature doesn't match, the server refuses to boot.
- IVPN completed their transition to RAM-only infrastructure through 2024-2025, following the same System Transparency principles.
The red flag: If a VPN says "RAM-only" but rents virtual machines from cloud providers (AWS, Google Cloud, etc.), they don't fully control the hardware. The cloud provider could theoretically snapshot the VM's memory. True RAM-only means bare-metal servers the VPN company owns or exclusively controls.
The quick check: Look for "[VPN name] RAM-only servers" or "[VPN name] diskless infrastructure" on their blog. If they've done it, they'll have a detailed technical post about it. If all you find is a vague FAQ answer, be skeptical.
How many trackers are in the app?
Why it matters: A VPN can have perfect server infrastructure and still spy on you through the app on your phone. Embedded trackers — tiny pieces of code from companies like Google, Facebook, and data brokers — collect device identifiers, usage patterns, and session data before your traffic even reaches the encrypted tunnel.
A French nonprofit called Exodus Privacy scans Android apps and publishes exactly which trackers and permissions each app contains. The results for VPN apps are eye-opening.
Here's what the data shows:
Mullvad: 0 trackers, 8 permissions (the bare minimum for a VPN tunnel)
IVPN: 0 trackers, 15 permissions (location and camera are optional, used for network protection and QR code scanning)
NordVPN: 3-4 trackers, 16-27 permissions (includes "Read Phone State")
ExpressVPN: 4 trackers, 25 permissions (includes precise GPS, camera, biometrics, external storage)
Surfshark: 3 trackers, 42 permissions (includes GPS override, background location tracking)
CyberGhost: 4-7 trackers, 11-15 permissions
Read that again. Surfshark — a privacy tool — requests 42 permissions on your phone. ExpressVPN wants access to your precise GPS location, your camera, and your biometrics. These apps embed SDKs from Google Firebase, AppsFlyer, and MixPanel — companies whose entire business model is tracking user behavior.
Meanwhile, Mullvad asks for 8 permissions (the absolute minimum to create a network tunnel) and contains zero tracking code.
The quick check: Go to reports.exodus-privacy.eu.org and search for your VPN app. Look at the tracker count and the permission list. If a "privacy" app has more trackers than your weather app, something is wrong.
Is the code open source?
Why it matters: If the VPN app's code isn't publicly available, you're trusting a compiled binary — a black box — with all your internet traffic. You have no way to verify that the app does what it claims. No way to check for hidden telemetry. No way to confirm the encryption is implemented correctly.
Open source means the code is on GitHub (or a similar platform) for anyone to read, audit, and verify. It doesn't guarantee the software is perfect — but it means thousands of eyes can check it, and hidden backdoors get found fast.
Who's open source:
- Mullvad: Full client suite (Windows, macOS, Linux, iOS, Android) is on GitHub. They even provide reproducible builds for Android — meaning you can compile the code yourself and verify the result matches the app on the Play Store, byte for byte.
- IVPN: All desktop and mobile apps are open source. Their philosophy is literally "don't trust, verify."
- Proton VPN: All apps are open source.
- NordVPN: Not open source. You're trusting the binary.
- ExpressVPN: Not open source (their Lightway protocol is, but the app itself isn't).
- Surfshark: Not open source.
The quick check: Search "[VPN name] GitHub" or "[VPN name] open source." If the full client app is on a public repository, that's a good sign. If only a single protocol library is open source while the rest of the app is closed, that's a marketing move, not transparency.
Who audits it, and how often?
Why it matters: An audit is when an independent security firm gets access to the VPN's code and servers to verify the privacy claims. But not all audits are equal. A one-time audit from three years ago tells you almost nothing about today's infrastructure. And a heavily scoped audit that only checks one server in one location is theater.
What good auditing looks like:
- Mullvad rotates between specialized cybersecurity firms (X41 D-Sec, Assured Security) for deep, white-box source code audits. In January 2026, X41 audited Mullvad's payment and account API with full, unredacted access to the backend. They found five issues (three medium, two low severity) — none of which could expose user data. The audit confirmed that Mullvad's VPN relays only see active encryption keys and have zero knowledge of which account those keys belong to.
- IVPN runs annual audits with Cure53, a respected German security firm. Their 7th consecutive audit was in May 2025. Cure53 gets access to both public and private code repositories.
- PureVPN (interesting case) was caught handing user logs to the FBI in 2017 — directly contradicting their "zero logs" marketing. To rebuild trust, they partnered with KPMG for an "Always-On" audit: KPMG can show up unannounced, at any time, to inspect live infrastructure. No advance notice. That's the most aggressive audit model in the industry.
What bad auditing looks like: A single audit, years ago, with a heavily redacted report, from a firm nobody's heard of, that only checked a handful of servers. If the VPN won't publish the full audit report, ask why.
The quick check: Search "[VPN name] security audit [current year]." Look for the auditing firm's name (Cure53, X41, Deloitte, KPMG are well-known). Check if the full report is published. If the most recent audit is more than 18 months old, the VPN may have changed significantly since then.
Where is it based?
Why it matters: The country where a VPN is legally incorporated determines what laws apply to it. Some countries can force companies to secretly hand over user data. Others have strong privacy protections that make this difficult or impossible.
The "14-Eyes" alliance — the US, UK, Canada, Australia, New Zealand, and nine European countries — actively share intelligence and have legal frameworks that can compel tech companies to cooperate with surveillance. A VPN based in one of these countries faces more legal pressure than one based outside.
Where the privacy-first VPNs are based:
- Mullvad: Sweden. The OVPN court case proved that Swedish law exempts properly engineered VPNs from ISP-style data retention requirements.
- OVPN: Sweden. Court-proven jurisdiction.
- IVPN: Gibraltar. Strong independent data protection framework, outside the core 14-Eyes apparatus.
- Proton VPN: Switzerland. One of the strongest privacy legal frameworks in the world.
Where the big VPNs are based:
- NordVPN: Panama on paper, but the parent company Nord Security operates from Lithuania — where it was incubated by Tesonet, a data mining and residential proxy conglomerate.
- ExpressVPN: British Virgin Islands on paper, but owned by Kape Technologies (Isle of Man/Israel/Cyprus).
- Surfshark: Netherlands (14-Eyes member). In April 2026, Surfshark disclosed in a transparency report that it fulfilled a warrant from the Amsterdam District Court. Their RAM-only servers prevented traffic log handover, but they confirmed the account existed and provided payment information.
The quick check: Jurisdiction alone doesn't make a VPN safe or unsafe. A well-engineered VPN in a 14-Eyes country (like OVPN in Sweden) can be more private than a poorly engineered one in Panama. But all else being equal, a privacy-friendly jurisdiction adds a legal buffer on top of the technical protections.
The comparison table
Here's how the major VPNs stack up across all seven criteria:
Mullvad — $5.50/mo flat · Sweden · 0 trackers · Full open source · RAM-only (stboot + TPM) · Raided, police left empty-handed · Audited by X41, Assured · Anonymous signup (no email, cash accepted)
OVPN — ~$4.99/mo · Sweden · Open source · RAM-only (iPXE, owned hardware) · Court-proven zero logs (Stockholm 2020) · Small but verified
IVPN — $6/mo · Gibraltar · 0 trackers · Full open source · RAM-only (2024-2025 transition) · Annual Cure53 audits (7th in 2025) · No email required
Proton VPN — $2.99/mo (2yr) · Switzerland · Open source · 4 consecutive Securitum audits · Free tier available · Email required
NordVPN — $2.69/mo (2yr) · Panama (parent in Lithuania/Tesonet) · 3-4 trackers · Not open source · 6 Deloitte audits · Server breach 2018 · Merged with Surfshark · Email required · Fast
ExpressVPN — $6.67/mo (1yr) · BVI/Kape · 4 trackers · Not open source · 25 app permissions · Project Raven connection · Owned by former adware company
Surfshark — $1.99/mo (2yr) · Netherlands (14-Eyes) · 3 trackers · Not open source · 42 app permissions · Merged with NordVPN/Tesonet · Complied with Amsterdam warrant (2026)
Which one should you pick?
If privacy is your top priority: Mullvad. Anonymous account, zero trackers, RAM-only, raided and proven, fully open source. It's not the cheapest, but it's the most verifiable.
If you want privacy with a free tier: Proton VPN. Swiss jurisdiction, open source, four consecutive audits, unlimited free plan.
If you want court-proven zero logs: OVPN. The only VPN whose "no logs" claim has been legally validated by a judge.
If you want the best balance of privacy and features: IVPN. Zero trackers, open source, annual audits, RAM-only, and a clean app with no bloat.
NordVPN and Surfshark are fine for streaming and general browsing. They're fast, cheap, and NordVPN has six Deloitte audits. But if you're choosing a VPN specifically for privacy, the Tesonet/data-mining lineage, the closed-source apps packed with trackers, the 2018 server breach NordVPN hid for 18 months, and the quiet merger that consolidated two "competitors" under one roof — all of that should factor into your decision.
ExpressVPN's ownership situation — Kape Technologies, Project Raven, privatization — makes it hard to recommend for anyone whose primary concern is privacy.
One more thing: your antivirus
A lot of people lock down their VPN, switch to encrypted email, use a privacy browser — and then run Norton or McAfee as their antivirus. Software that has root access to every file on their computer and shares data with advertising networks.
Avast was fined $16.5 million for selling browsing data from 100 million users. Norton bundled a crypto miner. Kaspersky got banned by the U.S. government.
If you care enough about privacy to research VPNs this carefully, your antivirus deserves the same scrutiny. XorShield AV runs its own detection engine — layered scanning that catches known threats, malware families, and brand-new samples right on your device. All scanning happens locally. No data collection, no cloud uploads, no account required.
$14.99/year. macOS, Linux, Windows.
