Fastly Next-Gen WAF Likes & Dislikes

Like

Could be the adaptability and customisability of the WAF which allows users to configure rules and policies to their specific needs. The performance and speed since it is running on Fastly global network which ensures that implementing these measures does not impact the site performance.

Like

It performs it's function well, does not consume a lot of computing resources, and is regularly updated with filtering rules based on threat intelligence to keep the protections up-to-date.

Like

Insights/ Metrics available from the tool. JA4 blocking capability Ability to automate va terraform

Dislike

Could bit difficult to do the initial setup depending on the environment as it offers different installation methods. Also it comes with a price as it offers premium and advanced protection compare to other WAF solutions.

Dislike

Some of the rules are opaque to the end-user, you don't exactly know what signals the rules are looking for, this makes it a little harder to evaluate whether you want to enable/use them.

Dislike

Initially lack of customisation for the captchas (but this has since been resolved). Some obscurity around bot classification/ rules (but also common across similar vendors) Still feels like there's some segregation between signal sciences and fastly platform - would be nice for this to be further unified (though it's already so much better than 2 years ago).

    Fastly were easy to work with during the procurement/ RFP process and responded clearly to all requirements/ questions. The product itself met all of our functional requirements and has been easy to work with and maintain. The product itself is effective in detecting and protecting against web attacks. The team we've worked with at Fastly have been incredible. There were a few challenges early on from a commercial perspective but the team responded to feedback effectively and the collaboration since has been great.
