A large attack surface poses significant security risks for organizations. The process of attack surface reduction involves reducing all possible entry points to your sensitive resources.
This is why attack surface reduction processes should augment attack surface management solutions that identify all IP addresses associated with your attack surface.
A vulnerability scanner can automatically assess all of the domains and devices within your attack surface that contain exploitable security vulnerabilities.
Penetration tests will uncover any gaps in your security control strategy that represent excessive attack surface exposure.
