You cannot defend what you do not know you own. Shadow IT, forgotten subdomains, exposed dev environments, leaked credentials and misconfigured cloud storage appear faster than annual assessments can catch them. External Attack Surface Management continuously discovers, inventories and monitors your internet-facing estate from an attacker’s point of view — across cloud, SaaS, on-prem and third-party infrastructure.
We run ASM as the discovery and validation backbone of a Continuous Threat Exposure Management (CTEM) program — the scope, discover, prioritise, validate and mobilise loop. Crucially, we don’t stop at a scanner’s asset list: our offensive engineers validate exposures by hand, separating the noise from the handful of internet-facing weaknesses an attacker could actually exploit and chain into a breach.
The output is a living, prioritised view of your real external risk — new assets flagged as they appear, exposures ranked by exploitability and business impact, and clear ownership for remediation. It is the natural complement to point-in-time penetration testing: the pen test proves depth, ASM keeps you honest between tests.
How it works
- 01
Seed & discovery
Establish known assets and continuously discover the unknown internet-facing estate.
- 02
Scope & prioritise
Map exposures to business-critical assets and rank by exploitability and impact.
- 03
Validate
Offensive engineers confirm which exposures are genuinely exploitable, cutting false positives.
- 04
Mobilise & monitor
Assign remediation ownership, track closure and continuously alert on new exposures.
Packages
Essential
Baseline external attack-surface discovery and validated exposure report.
Comprehensive
Continuous monitoring with validated prioritisation and change alerting.
Enterprise
Full CTEM program with ongoing validation and remediation governance.
