External attack surface monitoring

See your company the way an attacker does.

Sentric scans your domain from the outside — open ports, exposed paths, leaked secrets, weak email and headers — matches it against live threat intelligence, and hands you a report you can act on.

What Sentric finds

The doors you forgot you left open.

Most breaches start with something ordinary and exposed — a stray backup, a missing header, an email domain anyone can spoof. Sentric looks for exactly those, from the outside, the way a real attacker would.

Attack surface, mapped

Every reachable port, path and endpoint — plus the forgotten ones. Leaked secrets in public source, weak TLS, and the small misconfigurations that add up.

Live threat intelligence

Your surface is cross-referenced against thousands of active indicators of compromise from global feeds — refreshed continuously, not a stale list from last quarter.

Reports that hold up

A professional assessment PDF — severity, evidence and remediation — written for the person who fixes it and the board that signs off. Not a wall of raw scanner output.

Learns your stack

Sentric detects the technology behind a domain and adapts each scan to it — prioritizing the checks that actually hit for that stack, so results get sharper over time.

How it works

Point it at a domain. Get a plan.

Three steps, no install, nothing running inside your network. Everything happens from the outside, where the risk actually lives.

Point

Enter a domain — yours, or one you're authorized to test. Sentric needs nothing but the name.

Sweep

Sentric probes the external surface, fingerprints the stack, and matches every finding against live threat feeds.

Act

You get a ranked report: what's exposed, how serious it is, and the exact steps to close it — with an authorization letter on file.

The deliverable

A report your auditor will accept.

Findings are ranked by real severity and paired with evidence and a fix. A single exposure score tells leadership where you stand — and the next scan shows whether it moved. This is exactly the document you receive once payment clears.

Documented, not assumed.

Every engagement ships with a written authorization letter that defines scope, dates and limits — signed before anything runs. Sentric only looks at what's already reachable from the public internet: no intrusion, no data exfiltration, no surprises. It's security work you can put in front of your board, your clients and your auditors.
