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.

Detailed container image reports have improved vulnerability insight and support secure operations

Most valuable are the reports that are quite good, particularly the detailed ones for container image scanning. Tenable.io Container Security is giving me the vulnerability information of Docker images and the information about software bill of materials. However, my challenge at this time is that I am using all these solutions with GitLab Ultimate, and it does not support integration, so I am doing some alternate arrangements which are giving me operational complexity because I need to introduce something else instead of GitLab Ultimate. That is the primary concern regarding the benefits of real-time visibility into my containerized application security status.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"NGINX App Protect has improved the flexibility of services in our company and distributed new escalation applications."

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

"The solution has helped us greatly during this Covid period."

"NGINX App Protect's best features are auto-learning, which creates a profile of applications that are deployed, bot protection, and force protection, which lets you configure your brute force policy and alert for and prevent brute force attacks."

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

"NGINX App Protect is a good product and performs very well even when it is under stress."

"The most valuable feature of NGINX App Protect is its open source."

More NGINX App Protect pros

"The strong security provided by the product in the container environment is its most valuable feature."

"Nessus scanner is very effective for internal penetration testing."

"Currently, I haven't implemented the solution due to its deprecation by the site. However, I can highlight some benefits of Tenable Cloud Security, a cybersecurity solution with various features for scanning vulnerabilities in both cloud environments and on-premises container security."

Cons

"I think NGINX App Protect could be improved by having it come out of the box with NGINX."

"The contributions I think sometimes take a toll on you like you're going to spend a lot of time on the right contributions."

"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."

"Currently, the policies have to be handled manually, and you have to create from scratch, which can be a bit time-consuming, in a large environment."

"The price of NGINX App Protect could improve."

"The integration of NGINX App Protect could improve."

"They have a messy license model; it's not really made for microservice architecture. It's getting expensive really, really fast."

"Its technical support could be better."

More NGINX App Protect cons

"The initial setup is highly complex."

"They need to work on auto-remediation so it's easier for the security team to act quickly when certain assets or resources are deployed. The latest version has a CIS benchmark that you need to meet for containers in the cloud, but more automation is needed."

"The stability and setup phase of the product are areas with shortcomings where improvements are needed."

"I believe integration plays a crucial role for Tenable, particularly in terms of connecting with other products and various container solutions like Docker or Kubernetes. It seems that in future updates, enhanced integration is something I would appreciate. Currently, there is integration with Docker, but when it comes to Kubernetes or other container solutions, it appears to be a challenge, especially with on-prem scanners."

"I feel that in certain areas this product has false positives which the company should work on. They should also try to include business logic vulnerabilities in the scanner testing. Finally, the vulnerability assessment feature should be increased to other hardware devices, apart from firewalls."

"The support is tricky to reach, so we would like better-oriented technical support enabled."

"Tenable.io Container Security should improve integration modules. It should also improve stability."

"The solution's price is reasonable."

"The price of NGINX App Protect is not much different from the products that fall under the leader category of Gartner Magic Quadrant."

"The licensing fees for this solution are pretty expensive for what it does, but there is no alternative."

"There are no additional fees."

More NGINX App Protect pricing and cost advice

"It's best to be an institutional buyer and directly contact the sales team as they can provide over-the-top discounts for bulk orders."
