Know when your perimeter changes — before attackers do
Discover your network with CIDR scans, then monitor every host that matters. Get instant alerts when ports open, services change, or TLS certificates expire.
Skannr is in public preview. Features may change or break without notice. We value our early customers and actively welcome your feedback to shape the product.
From discovery to continuous monitoring
Three steps to know exactly what's exposed
Discover with CIDR scans
Add your network ranges and let Skannr map every host. See your entire attack surface on a visual network map — which hosts are alive, which ports are open, which services are running.
Monitor what matters
Promote individual hosts from your network map to dedicated monitoring targets. Each host gets its own scan schedule, TLS tracking, and change history — scanning as often as every 5 minutes.
Get alerted on changes
When a port opens, a service changes, or a TLS certificate is about to expire, Skannr alerts you instantly. See exactly what changed with color-coded diffs — like git for your network.
Built for teams who take security seriously
Everything you need to secure your perimeter
Deep Port Scanning
TCP connect scanning with banner grabbing and service detection. Quick scans for discovery, full 65K port scans for thorough coverage.
Change Detection
Every scan is compared to the previous one. New port? Changed banner? Service version upgrade? You'll know about it before anyone else.
Self-Hosted Scanners
Deploy scanner agents inside your network to scan internal hosts privately. Or use them to verify firewall rules — test what's visible from specific network locations vs the public internet.
TLS Monitoring
Certificate expiry tracking down to the minute. Hostname mismatches, chain issues, protocol versions — all monitored and alerted automatically.
Multi-Vantage Scanning
Scan from our shared cloud scanners and your own on-prem agents simultaneously. Compare what the internet sees vs what your internal network sees — catch firewall misconfigurations before attackers do.
