Security posture

Security you can
actually stand behind

No "unhackable" theatre. Just honest, layered protection — and a clear account of what we protect, how, and what we can't promise.

What we promise — honestly

Claims we're willing to put in writing, because they're true.

End-to-end encrypted

Message, call and file content is encrypted on your device with the audited Matrix protocol (Olm/Megolm). We don't hold the keys — we can't read it.

Your server, offshore

Run on a dedicated instance in a jurisdiction of your choosing. Your data doesn't sit inside a Big Tech cloud.

Minimal data by design

We collect as little as possible — no phone number required. What we don't have can't be leaked, sold, or handed over.

Audited, open protocol

We don't invent cryptography. Matrix is open and independently reviewed — used by governments and militaries.

Hardened infrastructure

TLS everywhere, HSTS, security headers, firewalling, fail2ban, automatic security updates and encrypted backups.

Gated registration

Sign-up is token/voucher based, not open to the world — cutting spam and abuse before it reaches your instance.

We never say "unhackable", "100% secure", or "no one can ever access it". Those are marketing lies. Honesty is the point.

What we protect — and what we don't

Security is defense in depth, not a magic checkbox. Here's the honest picture.

WhatHow it's protected
Content (messages, calls, files)End-to-end encrypted (Olm/Megolm) — we don't hold the keys
Data in transitTLS 1.2+/1.3, HSTS, modern ciphers
The serverContainer hardening, firewall, fail2ban, automatic updates
Your identityNo phone number, minimal data, private registration
Metadata (who talks to whom, when)Reduced, but not fully hidden — an honest limitation
A compromised user deviceWe can't protect a phone or laptop that's already infected
If our server were ever breached: your content is still end-to-end encrypted, so an attacker cannot read your messages or calls. They'd see minimal metadata and could disrupt service. That's exactly why E2E plus minimal data is the real shield — it limits the damage even in the worst case.

Defense in depth — the layers

No single control is enough. Protection comes from stacking them.

Cryptography

E2E by default, cross-signing, encrypted key backup and device verification.

Transport

Automatic TLS, HSTS preload, and a strict set of security headers (CSP, X-Frame-Options, nosniff, Referrer-Policy).

Application

Third-party trackers and error reporting off, guest access off — nothing phoning home.

Server

Gated registration (tokens, not open sign-up), aggressive rate-limiting on login, controlled federation.

Infrastructure

no-new-privileges, database never exposed publicly, isolated volumes, random credentials.

Operations

Encrypted off-site daily backups, monitoring, and a written incident-response plan.

Responsible disclosure

Found a vulnerability? We want to hear from you. Report it to security@sovryk.com (see /.well-known/security.txt). We don't take legal action against good-faith security researchers.

Security is a process, not a checkbox — this posture is updated with every infrastructure change.
