PT Network Attack Discovery is a network detection and response (NDR/NTA) system for detecting attacks on the perimeter and inside your network. The system makes hidden threats visible, detects suspicious activity even in encrypted traffic, and helps investigate incidents.

An external penetration test researches and attempts to exploit vulnerabilities that could be performed by an external user without proper access and permissions. An internal penetration test is similar to a vulnerability assessment, however, it takes a scan one step further by attempting to exploit the vulnerabilities and determine what information is actually exposed.

An internal penetration test uses a different way of dealing with the attacks and comes into the picture after completion of an external penetration test. In this test, the main focus is to identify what could be accomplished by an attacker who has internal access to your network.
