Attack Surface Management
Attackers continuously scan your external assets. You should too. ClairSec builds a continuous inventory of your external attack surface, scores it, and delivers it to you — including assets you didn't know you had.
What we map
We start with what you know and expand to everything visible to an external attacker — including assets you didn't know existed.
- Web domains, DNS records, and certificates
- IP ranges and registered ASN blocks
- Exposed ports and services
- Subdomains and unregistered legacy assets
- Open cloud infrastructure ports (AWS, Azure, GCP)
- Internet-facing APIs and development environments
- Exposed web technologies, libraries, and frameworks
- CDN configurations and third-party dependencies
- Credential leaks tied to your domains
- Public code repositories containing secrets
- Email misconfigurations (SPF, DKIM, DMARC)
- Shadow IT assets and undisclosed SaaS tooling
Continuous inventory, not a point-in-time scan.
Discover
We map your full external attack surface through DNS scanning, certificate enumeration, passive ASN reconnaissance, and historical registration data. This includes what your team knows about and what it doesn't.
Score
Every asset is scored: who owns it, what software it runs, how exposed it is, and what active threats are associated with it. Scoring is based on real context, not just port counts.
Report
Findings reach you through weekly alerts and a monthly prioritised report. We track how your attack surface changes over time and alert you when new assets appear or existing ones change.
Intelligence deliverables

Monthly risk report
A summary of your attack surface: what changed, what was remediated, open assets, and prioritisation for the coming month.
