How it works
Scan once, then watch forever
We analyze 100+ security signals across your site, grade them into a clear security score, and keep watching for changes.
Security signals such as HTTP headers, TLS and SSL, DNS, cookies, and CSP are scanned and scored into a letter grade, then continuously monitored, producing prioritized fixes, monitoring alerts, and a shareable report.
What you get
Scan, monitor, and prove it.
One assessment, continuous monitoring, and reports your team and auditors can trust.
Full security assessment
Headers, TLS, DNS, cookies, and CSP policies all checked, graded, and explained with ready to use fix instructions.
CSP violation monitoring
Real time browser CSP violation reports from your visitors, with one click proposed fixes you can paste into your policy.
Network error monitoring
DNS, TLS, and HTTP failures your users actually hit, captured via Network Error Logs your servers never see.
Daily monitoring & reports
Automated daily scans with email digest on changes, plus PDF exports and shareable reports for your team or auditors.
Why it matters
You can't secure what you don't scan, watch, and fix.
- Exposure goes unnoticed. Missing headers, weak TLS, and a permissive CSP stay invisible until they are exploited.
- Automated bots probe first. Scanners look for these exact gaps within minutes of a site going live.
- No baseline to measure against. Without a grade, it is hard to tell whether a change improved or weakened security.
- Security drifts between deploys. A single release can drop a header or weaken a policy without any signal.
- Certificates lapse quietly. TLS certificates expire, and the first sign is often a user hitting a browser warning.
- Violations accumulate unseen. New CSP breakages and network errors build up between manual scans.
- Findings are not fixes. A list of issues changes nothing until the change is applied.
- Reports sit unread. Without prioritized steps ready to paste, issues can stay open for months.
- Gaps return next release. Fixes get reintroduced when nothing keeps the standard in place.
