Default Encryption

True End-to-end encryption

Peerio encrypts all your messages and files right on your device, so they’re secure wherever they go - on any device, anywhere, to anyone.

Identity Verification

Validate your contacts

Peerio alerts you whenever a contact’s account seems compromised. We offer easy ways to verify that you’re talking to the right person, and not an imposter.


Control your privacy

Peerio’s end-to-end encryption guarantees that only you and your recipients can read what you share. No one else has access. Not even us.


Security audits

Peerio is independently audited by expert cryptographers at least twice a year. These experts try to break the apps, and identify any vulnerabilities that can be exploited as security threats evolve. If we don’t pass, we don’t ship.

Open Source

Complete Transparency

Peerio is open source so our code can be reviewed by developers to validate that we are doing what we say we are doing.

Bug Bounty

We encourage public review

Peerio is so confident that our app is secure, we offer a monetary reward to anyone who can find security bugs or vulnerabilities.
