What is External Attack Surface Management (EASM)?
External Attack Surface Management (EASM) is a new emerging concept which provides a way to continuously discover, fingerprint and assess all your Internet exposed (external facing) assets that may lead to compromise or leak if misconfigured, unmanaged or unpatched.
When it is not done continuously, External Attack Surface Management (EASM) can sometimes be called: RECON, fingerprinting or digital footprint.
We do not sell EASM independently but we use it as a first step for our PTaaS.
