Security First

How we protect your private keys

We apply layered safeguards to protect your SSH credentials.

AES-256 encrypted storage

Private keys are encrypted with Rails Active Record Encryption (AES-256-GCM). Even with DB leakage, plaintext keys are not exposed.

Encryption key isolation

Encryption keys are stored separately from the database, raising the bar for attackers.

Decrypted only when needed

Keys are temporarily decrypted only in memory during SSH sessions, then released immediately.

Open source and auditable

All security-relevant code is open source and auditable by the community.

100% Open Source · Transparent

What exactly do we execute?

No black box. The full code is on GitHub. We collect metrics through read-only SSH commands:

Scheduled execution:

$ top -bn1 # get CPU usage
$ free -b # get memory usage
$ df -B1 # get disk usage
$ uname -a # get system information

When viewing processes manually:

$ top -bn1 # real-time process list
$ ps aux # process snapshot

These are standard Linux read-only commands and do not modify your server.
