Audit your VPS security posture with a single command. No agents, no installs — just one line of bash. Instant analysis across network perimeter, OS hardening, and application hygiene.
No agents. No installs. No persistence.
One command — full security audit.
Run a single command on your VPS. The lightweight script inspects configurations, network states, and service health — then self-destructs.
Our engine processes the data — scanning ports externally, validating SSL certificates, and cross-referencing known vulnerability databases.
Receive a categorized security report with copy-paste fixes generated for your exact OS, distro version, and server configuration.
We designed the system so you don't have to trust us.
End-to-end encryption means we can't see your data — until you explicitly allow it.
You open 1bash.dev — a unique session key is generated. From this key, an encryption key is derived entirely in your browser. We never see it.
The open-source script runs on your VPS and encrypts all collected configuration data locally using your key before transmitting anything.
Encrypted data passes through our infrastructure. We store it, but cannot read it. We have zero access to your server's configuration details at this stage.
Your browser decrypts the data locally. You see everything the script collected — and can remove any accidentally captured sensitive information before proceeding.
Only when you approve does your browser send the decrypted data to our backend for analysis. Until that moment, your data is exclusively yours.
The bash script that runs on your server is fully open-source. Inspect every line before execution.
