There were a few limitations in the product. While evaluating it, we found a couple of gaps. Rate Limiting features were not completely developed. The new feature requests used to take a little longer. The product was not mature, which is why it did not have a couple of features we needed. There were limitations and gaps in the product because it was new. Some of the WAF features were missing. Custom rules did not work. We could not create more than 15 custom rules. We had to raise new feature requests all the time. We could not see the logic behind the rules.
