Room For Improvement

The level of granularity is not great, and as you cross a certain threshold, the cost goes up by twenty or thirty percent every time.

If it's a bot, we should differentiate the requests, whether they are automated or not.

Senior Cloud Security at a healthcare company with 5,001-10,000 employees
Centralized web firewalling has reduced our attack surface and protects multi‑cloud applications
AWS WAF can be improved by not being too sensitive for some data because with some XML, it is sometimes very sensitive. When we upload videos or photos, it is flagged as a malicious pattern, and sometimes it is not sensitive enough because some query patterns that have the capability to perform malicious actions still result in false positives from AWS. It would be better for AWS WAF if it not only had logs but also specific payloads or something that directly included the specific logs so we can have more detail in our analysis. I think it should be better if they improve their capabilities in reducing the attack surface and also have better visibility for OWASP top 10 web applications and the API. Regarding AWS WAF's AI capabilities, its governance and security are very good because our attack surface is mostly reduced. The new dashboard is a bit complicated; it is easier for non-technical users, but for technical professionals, it is sometimes confusing. While the security itself is good and the governance is good, I think it needs to improve the UI or the flow itself. The accuracy and reliability of AWS WAF's output is better than others. With the free version, it has a good filter with the attack surface and the reliability is good, but sometimes we need to adjust. With the free version, we also have to pay some amount of money if the number exceeds the default provided by AWS.

Load balancing and secure access have supported complex migrations and automation at scale
NetScaler has positively impacted my organization because I work for a system integrator and deploy it for customers. Many customers are really happy with NetScaler, except for the pricing, as Citrix has changed a lot of their pricing in the last two or three years when they transitioned to Cloud Software Group. However, despite that, I know customers are really satisfied with the technical capabilities that NetScaler provides. While I do not have specific outcomes or metrics from my customers, I think using Core Logic has made it much easier for the big municipality I mentioned to implement NetScaler as a total solution, thus speeding up their automation. There are likely many benefits, but I lack benchmarks or timing figures to quantify that.
