Long-term web protection has supported reliable traffic management but needs a simpler interface

NGINX App Protect is a good product. I have used both versions from F5 -also the free version- (I mean the NGINX/NGINX One/App Protect free trial period), and I think it is a good product. It's stable, affordable, and easy to manage. NGINX App Protect is a comprehensive security solution that combines advanced WAF, DoS protection, API security, and DevSecOps automation in a lightweight, scalable package ideal for modern cloud-native architectures. The adaptive machine learning capabilities are truly commendable, as the solution can establish traffic baselines and detect anomalies in real time. It automatically adjusts security policies, minimizing the need for manual intervention and reducing false positives. Additionally, it supports scalable deployment across diverse environments, including on-premises, cloud, Kubernetes, and containers, offering both flexibility and scalability I have experience with the web server, F5 load balancer, and similar products provided by Ergon, for eg. the web application firewall and the Microgateway for K8S. I'm also familiar with F5 BIG-IP products.

Behavioral AI has protected critical applications and now blocks complex external attacks

I think Salt Security could improve their implementations. The one that I saw was very complex and took quite a bit of time, and if the environment is unique at all, it takes quite a bit of time to figure out how to properly ensure that it will be implemented. A lot of times there is a steep learning curve for someone that hasn't been in it to figure out the APIs and really dig deep into it, but once you get used to it, it is easy. However, that ramp-up period could be tough. I think Salt Security could use a more enterprise focus. Some of the smaller companies that I have referred them to think it is a little bit too complex for them, so if they could come up with a different version or something a little bit easier to simplify their platform, they may be able to find more customers that way.

More NGINX App Protect pros
