Your Entire Security
Posture. One Dashboard.
Track domain registration wherever your names live—so renewals and ownership changes are harder to miss. Monitored sites are probed for uptime and reachability every five minutes from our infrastructure. Monitor email deliverability with SPF, DKIM, and DMARC. Layer on vulnerability scanning and compliance tracking. On paid plans, DMARC aggregate reports arrive at an address we host for you and show who is sending mail as your domain.

Deep Security Scanning, Automated
From domain DNS records to open ports and CVEs — scan everything that matters

Full DNS audit — SPF, DKIM, DMARC, MX records, WHOIS, nameservers, and domain expiration tracking, with renewal alerts at 30, 14, 7 and 1 days on paid plans.
SSL & TLS Analysis
Monitor certificate status, expiry dates, HSTS configuration, redirect chains, and TLS version support.
Vulnerability Scanner
Detect open ports, outdated software, and known CVEs. Scan profiles from quick to extreme, with history tracking. Scans run only on domains you have shown you own.

Five-minute uptime probes on every plan, and nightly re-scans with change alerts from Starter up
Uptime Monitoring
Every watched domain is probed every five minutes (3 on Free, 25 on Starter, 100 on Pro, all of them on Enterprise), with outage history.
Blacklist Monitoring
Every checkup looks up the domain's mail-sending addresses (or its web server, when it names none) on DNS-based blocklists, so a listing shows up in the results with the list that named it.
Security Posture Timeline
Visual score history over time so you can see whether your security is trending up or down.
Activity Feed & Alerts
An Alerts page with an unread count, plus push to the iPhone app, for anything that needs attention.

Dark web monitoring runs in the DomainGuard iOS app, not the web dashboard. Automatic SEO scans run daily on Pro and Enterprise, with an emailed report, and weekly on Starter. Accessibility results are evidence for a review and never establish WCAG conformance on their own.
