WAFs have been around for decades. What are the critical features of an optimal WAF?
First, you want to ensure using a Cloud-based WAF which can scale up or down as your traffic pattern changes. The WAF should also include AI/ML capability analyzing large amounts of data in order to minimize false positives and false negatives. Last, the WAF engine should be up-to-date and flexible so customers can custom it based on their unique use-case.
