SecureLunaQuiet checks.Daily reports.Always on.
Daily automated baseline checks (KISA · CIS · NIST · GB/T) — plus custom commands on a schedule (coming soon) so you can run and collect any check you need. Five-minute setup with one SSH key.
No credit card required · 1 server free forever
How it works
Five minutes to your first report.
Self-service. No agent installed on your servers — just a public SSH key you place yourself.
1. Register your server
Add a Linux host you operate (label, host, SSH user, port).
2. Install our public key
Append the key we generate to your server's ~/.ssh/authorized_keys.
3. Daily checks run quietly
Each night, SecureLuna runs read-only configuration checks against KISA, CIS, NIST, and GB/T checklists.
4. Report by morning
Pass/fail per item, prioritized findings, and a PDF in your inbox before 7 AM.
What you'll see
Your morning report, at a glance.
Pass / fail per check, prioritized findings, and a single compliance score — all delivered before 7 AM.

Roadmap
Your AI Security Analyst.
SecureLuna evolves from a daily report into an AI analyst that watches over your infrastructure while you sleep.
SoonAI configuration analysis
Large-language-model summaries of your daily report — what changed, what matters, what to do first.
SoonRisk prioritization
Findings ranked by exploitability and asset criticality so you fix the right things first.
SoonSuggested fix guides
Step-by-step remediation written for your specific OS, package versions, and configuration.
SoonOperational best-practice tips
Curated guidance on hardening posture, drift control, and audit-readiness.
SoonCompliance score
A single moving score across KISA / CIS / NIST / GB/T so progress is visible to non-technical stakeholders.
SoonTrend tracking
30-day and 12-month trend lines per asset and per check item.
Our security promise
Four commitments before you trust us with SSH.
Adding a server to SecureLuna means giving us a key to your home. Here is exactly what we do — and don't — with that key.
Private keys are sealed
Each asset's private key is encrypted at rest with AES-256-GCM using a server-side key. Decryption only happens in memory during a scheduled run.
Read-only checks
Baseline scans only run cat/grep/ss-style commands against config files, sysctl, and service states. Nothing is written, installed, or modified.
Data stays where you'd expect
Reports and findings live on our own infrastructure (no third-party data warehouse). You can hard-delete your tenant and everything in it at any time.
Revoke anytime
Remove the SecureLuna line from your server's ~/.ssh/authorized_keys and access is cut off immediately. No support ticket required.

New Linux 'Dirty Frag' Zero-Day Privilege Escalation Vulnerability Discovered
Named 'Dirty Frag', this new Linux zero-day vulnerability allows users to gain root privileges with a single command across major distributions such as Ubuntu, RHEL, CentOS Stream, AlmaLinux, openSUSE Tumbleweed, and Fedora. It is recommended to temporarily disable the related kernel modules (esp4, esp6, rxrpc) if using IPsec VPN and AFS file systems, as they may be affected.
