What is the Phishing Reply Test?

KnowBe4's Phishing Reply Test (PRT) is a web-based tool that helps you determine which of your users are most likely to reply to highly-targeted phishing attacks, such as Business Email Compromise (BEC) and CEO fraud attacks. These types of attacks work by tricking your user into completing a task for someone they think is one of their co-workers or even a C-level executive, but is actually an imposter. This task could be anything, from providing sensitive information to wiring money. PRT can help you see how likely your users would be to fall for this type of attack should a real attack ever occur.

PRT allows you to send your users one of three pre-built phishing templates and tracks how many users reply. PRT will never save any of the information included in a reply. We only track whether the user replied, not the contents of that reply. We recommend spoofing someone from your own organization for more accurate results but make sure you get their permission first.

Follow these steps below to complete your free PRT. You will not be required to download or install any software. The default test is limited to 100 employees. Please contact us if you need to send to more.

Setting Up a Phishing Reply Test

For whitelisting information, click here. If you are using a firewall, contact our support team to ask for the domains that you will need to whitelist for this test. Also, consider your mail server or mail filter may have rate limiting in place which could prevent a large number of emails from being delivered at once and settings might need to be adjusted.

  2. Under the Free Phishing Reply Test, click the Get Started button.
  3. Enter the name and email of the sender you are trying to spoof in the corresponding fields. We recommend you use the email address of one of your C-level executives or the head of the department you are trying to spoof.
