The ease of use and the huge selection of real world phishing templates. Pretty straightforward integration with auth systems. Great support staff, quick response questions.

I really like the easy of use of the hook security platform. I was able to learn the platform quickly and implement the solution quickly to resolve the email security issues

I like the methodology of the training material. Hook isn't focused on the "haha, gotchya, and you're a terrible risk in our organization" -- they're focused on the "let's learn together how to become more security-aware". To get employees to participate in the training, they have two methods - humorous and more formal - to match your Org's culture. I was very thoughouly onboarded by one dedicated person who built a customized task list with videos which helped tremendously. After using and demoing several competitors, I feel 100% comfortable recommending Hook to others. While they're a "smaller" company at the time of writing, that doesn't stop them from having all of the "big" company features, plus some.
