External vs. Internal Penetration Test

The difference between an external and internal penetration test is what exactly is being tested.

  • External Penetration Testing
    The external penetration test will evaluate vulnerabilities and risks related to your network’s outside perimeter, those devices, and systems exposed to the outside world. 
  • Internal Penetration Testing
    The internal penetration test evaluates the vulnerabilities within a network.

Which Do I Need?

Testing both is important. While making sure your external defenses are strong is critical, knowing that your internal network is as secure as possible is also imperative. Malicious actors can gain access to your internal network through exposed vulnerabilities or social engineering activities. A disgruntled employee could obtain access to information they should not have and leverage it against an organization by selling personally identifiable information or credit card information on the dark web.
