SiteGuardian

Website monitoring for security, accessibility and EU compliance.

Screenshot of SiteGuardian

SiteGuardian answers a simple question: what is broken on your website right now, and which of it turns into a legal problem? The free scanner returns a security rating in about 30 seconds, no account needed. Monitoring runs uptime, keyword, SSL, domain (RDAP) and e-mail checks continuously, with alerts on nine channels including Telegram and webhooks.

The European Accessibility Act has applied since June 2025. SiteGuardian audits pages with Playwright and axe-core against WCAG 2.2 AA and produces reports clients use for their accessibility statement. The compliance engine normalises controls across 17 frameworks and exports evidence as PDF, with SAML/OIDC single sign-on and a hash-chained audit log.

An MCP server makes the checks available to AI assistants such as Claude, Cursor or Windsurf — one example of security tooling and agents growing together.
