Everyone talks about VPNs, but what actually keeps your data safe with Forest? Picture your data as a precious letter. AES‑256 encryption locks it up so that only you can read it, turning every byte into a coded message nobody else can decipher.

Encryption in Action

Forest uses AES‑256, the industry‑standard that feels like a steel vault. It’s a symmetric cipher: the same key both encrypts and decrypts, but that key never travels over the network. When your device talks to a Forest server, every packet is wrapped in this lock before it leaves, so even if a hacker taps the line, all they see is gibberish.

Protocols: OpenVPN vs WireGuard

Protocol

Speed

Security

Compatibility

OpenVPN

Moderate

Mature, proven

Windows, macOS, Linux, iOS, Android

WireGuard

Fast

Modern, lean codebase

Windows, macOS, Linux, iOS, Android

We support both because speed and security aren’t mutually exclusive. WireGuard’s 4‑line kernel module gives lightning‑fast handshakes, while OpenVPN’s extensive configuration options let you fine‑tune control. Think of WireGuard as a bullet train and OpenVPN as a reliable freight line—both get you there safely.

DNS Leak Protection

Without protection, DNS queries can leak outside the tunnel and expose the sites you visit. Forest’s built‑in DNS leak guard forces every query through the VPN, like a secret tunnel that hides your footsteps. We test this daily with real‑world tools to confirm no leaks slip through.

No‑Logs Policy & Independent Audits

We don’t keep records of your traffic. Our no‑logs stance means there’s nothing to hand over, even if a court demands it. Independent audits by a third‑party firm verify our claims, and the results are publicly available for anyone who wants to double‑check.

GDPR Compliance

Data residency matters. Forest stores logs—only minimal connection metadata—within the EU, and all encryption keys are generated on‑device, never on a server. This meets GDPR’s strict data‑processing guidelines, giving you peace of mind.

Real‑Life Breach Scenario

Imagine a hacker intercepts a corporate VPN session that uses weak 128‑bit encryption. They capture the traffic, decrypt it, and steal credentials. With Forest’s AES‑256 and no‑logs policy, even if a packet is snatched, it remains unreadable, and there’s no stored history for the attacker to exploit.

Checklist Before Sensitive Work

  1. Confirm connection status: VPN icon shows Connected and IP matches Forest’s range.
  2. Test DNS leak: Visit https://www.dnsleaktest.com/.
  3. Verify encryption: Use https://www.howsmyssl.com/ to see TLS 1.3.
  4. Check no‑logs: Review Forest’s audit report.
  5. Confirm GDPR compliance: Ensure server location is EU‑based.

Ready to lock down your data? Forest’s layers of encryption, robust protocols, and strict privacy policies mean you can work, stream, and browse with confidence.
