The average team underestimates its own external footprint by 30–40% — a staging box someone spun up in 2023, a marketing subdomain pointed at a dead CDN, an API gateway nobody owns. Secuur finds all of it, then grades every TLS endpoint on the same A–F scale as the free scan.
Attack surface visibility is the unglamorous foundation everything else sits on. Penetration tests scope to what you tell the tester about. Compliance evidence covers the systems you listed. Automated scanners only scan the targets in the queue. Every one of those activities inherits the blind spots of your inventory.
Secuur builds the inventory from the outside in — the same way an attacker would. We start from your domains and enumerate subdomains, resolve them, fingerprint what is listening, pull and parse every certificate, and attribute each asset back to a business owner. Then we keep doing it, because your surface changed while you were reading this.
Passive sources plus active resolution across your registered domains. Catches the forgotten staging., old-app. and vendor-hosted CNAMEs.
What is actually listening on each resolved host, what software version it reports, and whether it should be internet-facing at all.
Every leaf and chain you present publicly — issuer, key type, key size, signature algorithm, SAN sprawl, and days to expiry.
CNAMEs pointing at deprovisioned cloud resources are a subdomain-takeover waiting to happen. We flag them the day they go stale.
An asset with no owner never gets patched. Each finding is tagged to a team so remediation has an address to go to.
New host, new certificate, downgraded cipher suite, expiring cert — delivered to email, SMS or webhook the same day it appears.
Conventional attack-surface tools tell you a host exists and what version it runs. They will not tell you that its TLS handshake negotiates a classical-only key exchange — which means every session it has ever served is harvestable today and readable the moment a cryptographically-relevant quantum computer exists.
You give us your domains — or just your primary one and we work outward from registration and certificate-transparency records.
First full sweep completes in hours, not weeks. Every live TLS endpoint comes back with an A–F quantum grade attached.
Continuous re-discovery on your cadence. You get a diff, not another 400-row dashboard to go read.
A vulnerability scanner tests targets you give it. Attack surface visibility discovers the targets in the first place. The two are complementary — discovery feeds the scanner its queue, which is why Secuur runs them together.
No. External discovery runs entirely from the outside using public DNS, certificate transparency logs and unauthenticated network probes — the same data any attacker can reach. Authenticated internal discovery is available as an add-on where you want cloud-account coverage.
A CBOM is an inventory of every cryptographic algorithm, key and certificate your systems depend on. It is the prerequisite for any post-quantum migration plan, and US federal guidance under NSM-10 and CNSA 2.0 increasingly expects agencies and their suppliers to maintain one.
Weekly by default, daily or continuous on higher tiers. Certificate expiry and new-host events are alerted as soon as they are observed rather than waiting for the next full sweep.
Continuous scheduled scanning at fleet scale — every domain, every week, without spending an analyst on it.
Evidence for SOC 2, HIPAA, PCI DSS 4.0, CMMC and CNSA 2.0 — generated from live systems, not assembled by hand the week before.
Human-led testing against your applications, network and cloud — with findings written for engineers and evidence written for auditors.
The scan is free and takes 20 seconds. It also tells us enough to scope attack surface visibility properly instead of guessing.
