Discover · External Attack Surface
Continuous discovery of every internet-facing exposure
Validate the assets, certificates, services and identities that an external attacker reaches first — within minutes of them appearing.
- Production-safe by default
- Continuous, not scheduled
- Reproducible exploitation evidence
- Auto-mapped to PCI / ISO / SOC 2

ValidatedThe problem
External attack surface drifts faster than EASM tools observe it
Cloud workloads spin up. Marketing teams ship subdomains. M&A integrations expose forgotten infrastructure. Most attack-surface tools enumerate; none of them validate exploitation.
Attackers do. They find the new asset hours after it goes live, fingerprint, exploit and pivot before EASM finishes a scan.
The KeenSafe approach
Discover, fingerprint and validate — continuously
KeenSafe runs continuous external discovery (DNS, certs, ASN sweeps, paste/code leaks, certificate transparency) and immediately validates exploitation against new assets — production-safe.
Output is not a list of assets. It is a list of validated external entry points, each with an evidence-backed exploitation chain.
Capabilities
What ships in this engagement
Continuous Discovery
DNS, certs, ASN, code leaks, CT logs and subdomain takeover candidates — new assets surfaced in minutes.
Service Fingerprinting
TLS, HTTP, banner and version fingerprinting matched against live exploit chains.
Exploit Validation
Auth bypass, RCE candidates, default creds and known CVE chains — only validated paths surface as risk.
External-to-Internal Pivot
OAuth misuse, leaked CI tokens, identity foothold detection — handed to internal-pentest agents to walk the chain.
Shadow IT Detection
Subdomain takeovers, abandoned cloud assets, expired certs and orphan DNS records.
Compliance Mapping
PCI DSS 11.4, ISO 27001 A.12.6, SOC 2 CC7.1 — auto-mapped per finding with auditor-ready exports.
Attack path
How attackers actually move
External attack paths almost always begin at the cheapest entry — an exposed API, a forgotten subdomain, a leaked token. KeenSafe validates which of these chains into actual internal reach.
Validated chain
Subdomain takeover → SaaS impersonation
Orphan CNAME on legacy.target.com→claimed by attacker→phishing kit hosted under brand→SSO consent abuse
Business impact
Brand-trust phishing path validated and closed
Outcomes

For the board
For the executive: the only number that matters externally
"How many internet-exposed paths into our environment exist today?" KeenSafe answers it continuously, with evidence. That number is the input most insurers and regulators now request.
Risk reduction over time is graphable; closure is verifiable.
Technical validation
External validation methodology
A four-stage external loop runs continuously: discover → fingerprint → exploit-safely → chain-into-internal. Production-aware throttling, signed evidence, scope-bounded targeting.
- 01Continuous DNS / cert / ASN / paste / CT-log enumeration
- 02Per-asset service + version fingerprinting
- 03Production-safe exploitation per known + emerging CVE chains
- 04External-to-internal pivot detection (OAuth, federation, leaked secrets)
- 05Reproducible evidence per validated chain
