Monitoring
Uptime, certificates, DNS, headers, page changes, attack surface and reputation.
Monitoring: what is watched and when you are alerted
Uptime, TLS certificates, DNS, security headers and page changes, what each one checks and the alerts it raises.
Defacement and page-change monitoring
How we notice tampering, new external scripts and unexpected content, what is ignored and how to review changes.
Attack surface discovery
Find hosts under your verified domains. Discovery never scans what it finds.
Blocklist reputation monitoring
Be told when your server's IP address or domain appears on a public blocklist.
