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.

Pros

"The stability of the product is very impressive since it handles 60,000 to 70,000 requests or transactions per second."

"Based on my experience, this solution is better than the other choices on the market."

"NGINX App Protect has complete control over the HTTP session."

"There's a cache, or it works like a proxy, so it can speed up applications."

More NGINX App Protect pros

"Salt Security gives you visibility of all your APIs, identifies API security issues, and immediately alerts you of attacks."

"Salt Security has positively impacted my organization and my client's organization by being able to stop cyberattacks and ensure that they have proper security over all their applications, giving them a sense of peace of mind that they have security over something that could ultimately take down the whole company if not mitigated properly."

"It's really great. I would rate the stability a nine out of ten. I haven't encountered any instability issues."

"Salt Security gave me much better visibility into API risk, helping me identify exposed endpoints, misconfigured APIs, and sensitive data flowing through APIs that required additional controls, and it has become an important part of my API security program."

Cons

"The setup of NGINX App Protect is complex. The full process took one week to complete. Additionally, we had to change the network infrastructure platform which took one month."

"NGINX App Protect would be improved with integration with Shape and F5 WAF, which would make it easy for users to manage all their web application security with a single solution."

"They could provide a better user interface."

"The support from NGINX App Protect is too expensive."

"It's challenging if you need to go for a high throughput."
