If your organization uses VIPRE's Email Security for spam filtering, you can whitelist KnowBe4 to allow our simulated phishing emails and training notifications to reach your end users. You can also whitelist KnowBe4's phishing and landing domains in VIPRE Endpoint Security to allow your users to access phishing test landing pages.

The instructions below are for third-party software. If you have issues whitelisting KnowBe4 in VIPRE, we recommend that you contact VIPRE for assistance.

Whitelisting by IP Address

Typically, we recommend whitelisting our IP addresses in your spam filter. To whitelist our IP addresses with VIPRE Email Security, follow VIPRE's Guided Setup of VIPRE Email Security Cloud and whitelist by IP address.

For the most up-to-date list of our IP addresses, see the IP Addresses, Hostnames, and Header Information section of our Whitelisting Data and Anti-Spam Filtering Information article. 

Whitelisting by Hostname

If you are unable to whitelist by IP address, you can whitelist our mail server hostnames instead. To whitelist our hostnames with VIPRE Email Security, follow VIPRE's Guided Setup of VIPRE Email Security Cloud article and whitelist by domain.

For the most up-to-date list of our hostnames, see the IP Addresses, Hostnames, and Header Information section of our Whitelisting Data and Anti-Spam Filtering Information article. 

Whitelisting Landing Pages

To allow landing pages attached to your phishing campaigns to reach your users, you can whitelist our phishing and landing domains. To whitelist phishing and landing domains in VIPRE Endpoint Security, request the list of root phish and landing domains from the KnowBe4 support team. Then, see VIPRE's Add Allowed Websites article to add these domains to VIPRE.
