External Attack Surface Management: See Your Attack Surface Before Attackers Do
EASMLens is external attack surface management (EASM) software: it finds the domains, subdomains, certificates and email records your organisation exposes to the internet, and alerts you to changes after each scan. Discover, assess and monitor internet-facing assets on a schedule, from forgotten subdomains to unauthenticated APIs. Agentless discovery, vulnerability and exposure intelligence and AI-powered prioritisation, from the attacker's point of view.
Country guidance: EASM in Australia, New Zealand, Singapore, the UAE and Saudi Arabia.

What we find
Every Exposure an Attacker Would Target
Your attack surface is more than your website. EASMLens hunts the exposures that cause real breaches, continuously and from the outside in.
Vulnerable & Unauthenticated APIs
API endpoints answering without authentication, broken auth flows, exposed OpenAPI specs and leaked keys, found before attackers script them.
Exposed Services & Databases
Admin panels, RDP/SSH, Elasticsearch and Postgres replicas answering on the open internet, fingerprinted and flagged as soon as they appear in internet-wide data.
Shadow IT & Forgotten Assets
Marketing microsites, trial SaaS tenants, staging servers and acquisitions nobody inventoried, discovered through DNS and certificate records.
Subdomain Takeover
Dangling CNAMEs pointing at unclaimed cloud origins: the classic path to phishing on your own domain, listed in the domain intelligence report.
Certificate & TLS Hygiene
Expiring certificates, weak ciphers, deprecated TLS versions and mismatched hostnames across every endpoint you own.
Cloud Storage Exposure
Coming soon: public S3 buckets, Azure blobs and GCS objects carrying backups, credentials or customer data, identified and prioritized by risk.
API attack surface
Authenticated APIs vs Vulnerable APIs
APIs are now a leading attack vector, and most organizations can't list the ones they expose. EASMLens discovers the endpoints visible on your estate and grades their exposure, so you know exactly which APIs are managed and which are an open door.
Authenticated & Managed APIs
Where you want every endpoint to be
Inventoried & owned
Every endpoint mapped to a business owner and a known service.
Authentication enforced
OAuth2 / OIDC, mTLS or signed tokens on every route, with no anonymous access to data.
Least-privilege scopes
Tokens carry narrow scopes; object-level authorization checked, not assumed.
Versioned & monitored
Deprecated versions retired on schedule; traffic anomalies and new routes alerting in real time.
Unauthenticated & Vulnerable APIs
What EASMLens finds before attackers do
Unknown & unowned
Shadow endpoints from old releases, partners or acquisitions that are invisible to your inventory.
No or broken auth
Routes answering without credentials, BOLA/IDOR flaws, JWTs accepted without signature checks.
Secrets in the open
API keys in JavaScript bundles, exposed Swagger/OpenAPI specs, verbose error responses.
Forgotten versions
v1 still answering next to v3: unpatched, unmonitored and indexed by attackers' scanners.
Continuous API discovery, from the outside in
No traffic mirroring, no agents. EASMLens finds endpoints the way attackers do, from DNS, certificates and internet-wide data, then re-checks each one's authentication posture on every scan cycle with non-destructive checks.
Platform Capabilities
Comprehensive attack surface management with enterprise-grade security controls
Scheduled Asset Discovery
What it covers:
Subdomains, IP addresses, third-party services, shadow IT. Cloud resource discovery is coming soon.
How it works:
EASMLens maps your external attack surface from DNS records, certificate transparency logs and internet-wide scan datasets, with nothing to install on your systems. Discovery uses public sources and light, standard web requests; active checks such as port scans run only on DNS-verified domains.

How It Works
Four-step continuous security process
Check your domain's email security
Enter a domain to see how its SPF, DMARC, DKIM, MTA-STS and other public email records are set up. Free, with no sign-up, and each result comes with the fix in plain English.
