Vulnerability scanning built for security, not just compliance.
Sentinel continuously scans everything you have facing the internet — domains, subdomains, IPs, web apps, cloud, and containers — and tells you what an attacker could actually use. Our team reviews every result, so you get real issues with a fix, not a wall of alerts.
Included with every Securest engagement. No agents to install for external scanning.
Stronger security and a cleaner audit come from the same work.
Most teams start scanning because a customer or an auditor asked. What they get is a clearer picture of their own infrastructure than they've ever had — and the compliance evidence falls out of it.
You can't secure what you don't know about
Forgotten staging environments, a subdomain from a project two years ago, a database port left open during a migration. Sentinel maps what's actually reachable from the internet, then re-checks it every cycle as your infrastructure changes.
A finding without a fix is a liability
Every issue we surface includes what it is, why it matters, and the specific change that closes it — written for engineers, not security specialists. Our team helps you sequence the work and confirms the fix landed on the next scan.
The evidence is a by-product, not a project
SOC 2, ISO 27001, and HIPAA all expect ongoing scanning with findings tracked to closure. Running the program produces that record automatically — scan history, severity, ownership, and resolution, mapped to the controls it satisfies.
Five steps. One of them is yours.
You authorize the assets. We do the rest.
Authorize the scope
You tell us what we're allowed to scan. Subdomains inherit authorization from the parent domain. We log who approved it and when.
Find what's actually exposed
We enumerate your subdomains, scan for open ports, and fingerprint what's running on each one. It's usually more than people expect.
Scan on your cadence
We recommend weekly. Monthly is the floor. Every discovered service gets checked against a version-pinned template library, plus OWASP Top 10 testing on your web apps.
Cut the noise
Info-level findings are suppressed on ingest. Low and medium go through one of our analysts. High and critical reach you with guidance already attached.
Fix it and prove it
You get the report and the vulnerability dashboard. We can open the Jira ticket, work the plan with you, and confirm the fix on the next scan.
The engines underneath
We tried sending clients to Rapid7 and Tenable first. The tools were fine. Getting evidence out of them that satisfied an auditor, and getting them to play nicely with Secureframe and Vanta, was not. So we built our own on top of the same industry-standard engines, version-pinned so every report is reproducible.
Your external attack surface. Subdomain discovery, port and service enumeration, and CVE detection against a template library that updates within hours of a new disclosure.
Web app testing against your live services, authenticated or not. You give us an exclusion list so nothing touches logout, delete, or anything else destructive.
Containers and images. The vulnerabilities your base image and your dependencies brought along without telling you.
Cloud posture across AWS, Azure, and GCP, mapped to the same control set as everything else.
Internal network scanning behind the firewall. Servers, workstations, and databases that never face the internet.
Every scan lands in our review queue before it lands in yours.
Scanners are noisy by design — they report everything and let someone else decide what matters. That someone is us. Our analysts verify each result, discard what isn't real, rank what is, and attach the fix before it reaches your dashboard. You spend your time remediating instead of investigating.
Severity sets the deadline
Critical and high get fixed on a clock. Medium and low can go on the risk register with a documented decision — a legitimate answer, and one auditors accept when it's written down.
High → 30 days
Medium → 90 days
Low → best effort
Findings are never deleted
Fix something and it's marked resolved, then verified on the next scan — it doesn't vanish. That history is what an auditor tests: when it appeared, who owned it, how long it took, and whether it stayed fixed. If it reappears, it reopens automatically.
Work it where your team already works
Push a finding to Jira with the severity, affected hosts, and remediation steps prefilled, or track it in the vulnerability dashboard. Either satisfies an auditor, as long as the tracking is real and the dates line up.
Disable TLS 1.0 and 1.1 at the load balancer and restrict the cipher suite to TLS 1.2+ with forward secrecy. In AWS, attach the ELBSecurityPolicy-TLS13-1-2-2021-06 policy to the listener, then re-scan to verify.
Auditor-accepted evidence, and a security posture that actually improved.
After every scan you get a branded, timestamped, framework-mapped report written for your auditor — alongside the working record of what was found, who fixed it, and when.
Audit-ready PDF report
Scope, methodology, findings by severity, and a per-control evidence appendix. Hand it over as-is.
Live vulnerability dashboard
Severity, source, first and last seen, owner, and remediation status for every finding.
Scan history and evidence trail
Proof the program ran on schedule, cycle after cycle, retained for the full audit period.
Remediation guidance
The specific change that closes each finding, reviewed by the analyst who triaged it.
Frameworks: SOC 2 · ISO 27001 · HIPAA
Report ID: SNT-2026-0914-AH
Immutable artifact. Timestamped, version-pinned scanner templates, retained for the full audit period.
Push findings straight into your GRC platform as evidence.
Reports don't sit in a shared drive waiting for someone to remember them at audit time. Each scan is pushed into your compliance platform and attached to the controls it satisfies, on the same cadence your evidence collection already runs.
As the #1 Secureframe MSP partner, this is the part we've done a few hundred times. Pick your platform to see where the report lands.
Unmapped findings surface as uncategorized — never dropped.
Internal network scanning, for when external isn't enough.
External scanning covers SOC 2 and HIPAA scope. ISO 27001 A.8.8 — and the more thorough auditors — expect coverage behind the firewall too: servers, workstations, and databases that never touch the internet.
Internal scanning runs on a dedicated appliance reachable by agent or VPN, and feeds the same dashboard, the same triage queue, and the same report. It's a separate module with its own scoping and security review — talk to your vCISO about whether your scope needs it.
-
Same dashboard, same reportInternal findings land in the identical triage queue and PDF template — no second tool to learn.
-
Agent or VPN reachableDeployed on a dedicated appliance inside your network. Nothing internal is ever exposed outward.
-
Required for ISO 27001 A.8.8Full technical vulnerability management coverage, which external-only scanning doesn't satisfy.
-
Scoped separatelyIts own contract and security review, so the blast radius is agreed before anything is deployed.
A pentest is a snapshot. Your vulnerability program runs continuously.
Both come up in every audit cycle, and they answer different questions. Sentinel doesn't replace a pen test — we arrange those too. Here's how they fit together.
How far could someone get?
A specialist spends days chaining weaknesses together to prove real-world impact — the kind of judgment no scanner replicates. It's a point-in-time assessment, usually annual, and it reflects your environment on the day it ran.
What's exposed right now?
Every asset checked against thousands of known vulnerability signatures, every cycle. It catches the certificate that expired last week and the service someone spun up on Tuesday — the changes that happen between pen tests.
Depth once, coverage always
The pen test finds what automation can't reason about. Continuous scanning makes sure the gap between tests doesn't become the gap someone walks through. Auditors expect evidence of both, and they check the dates.
Let's scan your external attack surface.
Give us your domain and the frameworks you're working toward. We'll get authorization on file, run the first scan, and walk you through the findings with a vCISO — not a PDF dropped in your inbox.
Every scan is authorized in writing before it runs, per asset, with the approver and timestamp logged.
