FAQ
Questions we get asked
- What is external attack surface management (EASM)?
- EASM is the practice of continuously discovering and validating internet-facing assets attackers can reach, then prioritizing remediation.
- What does CixOcean External Attack Surface do?
- It discovers assets from primary web or API starting points, validates DNS, inspects ports and services, confirms exploitable issues, guides remediation, and keeps monitoring with alerts and reporting.
- Does it find undeclared or shadow IT assets?
- Yes—within the product’s discovery model it surfaces declared and undeclared assets, including shadow IT tied to your primary domains and APIs.
- Is monitoring continuous?
