Your external attack surface,
monitored continuously.
Sentinel is SecurityLens's proprietary monitoring platform. It maps your digital footprint, runs continuous external scans, and surfaces what matters — so your team can focus on the fix, not the search.
Technology identifies potential issues. Experience determines what matters.
Sentinel is an External Attack Surface Management (EASM) platform built specifically for SMEs. It continuously monitors the perimeter of your business from the outside — the same view an attacker has.
Unlike generic scanners that produce long lists of raw findings, Sentinel applies security judgment: findings are triaged, false positives filtered, and every issue is explained in plain English with a specific remediation step.
What Sentinel monitors
Auto-discovers shadow IT and forgotten assets attached to your main domain.
Flags services that should not be reachable from the public internet.
Expiry alerts, weak ciphers, and misconfigured chains caught before they cause downtime.
Common CVEs, injection points, and security header misconfigurations across your web properties.
SPF, DMARC, DKIM records checked to reduce email spoofing exposure.
Public S3 buckets, exposed admin interfaces, and misconfigured cloud resources.
From domain to dashboard in minutes
Enter your primary domain. Sentinel maps your full external footprint — subdomains, IPs, cloud assets — automatically.
Sentinel runs scheduled scans across your attack surface. You set the cadence; we handle the rest.
When something new appears or an existing asset changes state, Sentinel flags it immediately — not at the next scheduled report.
Every finding comes with a severity rating, plain-English explanation, and a specific remediation step. No noise, no jargon.
One view of your entire external posture
The Sentinel dashboard gives you a live risk score, asset inventory, finding timeline, and remediation queue — all in one place. Built for people who are not security experts, but need to act like they are.
Reports your board will actually read
Every Sentinel report is a branded PDF designed to be understood by a non-technical reader. Executive summary at the top. Findings ranked by business impact. Remediation steps in plain English at the bottom.

Common questions
No. A penetration test is a point-in-time, human-led engagement that goes deep into one area. Sentinel is continuous external monitoring — it watches the surface of your entire digital footprint over time. The two complement each other. Many clients run Sentinel year-round and commission a penetration test annually.
Free scanners give you a raw list of findings with no context. Sentinel applies experience: findings are triaged by severity, false positives are filtered, and every issue comes with a remediation step written for a non-technical reader. You also get change detection — so you know when something new appears, not just a snapshot of today.
No. Sentinel only tests what is publicly reachable from the internet — your external attack surface. Internal network testing requires a separate engagement and explicit authorisation.
Sentinel uses passive and low-intensity active techniques designed not to disrupt live services. We have run thousands of scans without causing downtime. If you have sensitive infrastructure, let us know and we will adjust the scan profile.
For Essential and Professional subscribers, critical findings trigger an immediate email alert. We will also reach out directly to walk you through the risk and recommended action. You are never left to figure it out alone.
Yes, on the Enterprise plan. A number of SecurityLens partners use Sentinel to power their own client reporting. Get in touch to discuss.
