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

"The most valuable feature is that there is a link in the system that will help to analyze the security of an application when something abnormal is found."

"We were looking for a product that is capable of complete automation and a container based solution, and it's working."

"It is a stable solution."

"The solution is very good overall."

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

"This solution provides perfect protection for the published services against all application attacks."

"The most valuable feature is that I can establish different services from the firewall."

"We use NGINX for security headers, and as a proxy; it is also a very good tool for load balancing."

More NGINX App Protect pros

"It helps us secure our applications from the build phase and identify the weaknesses from scratch."

"It is a scalable solution. Scalability-wise, it is a good solution."

"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."

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

"Tenable.io detects misconfiguration when you deploy a Docker or Kubernetes container. It's much better to remedy these issues during deployment instead of waiting until the container is already in the production environment."

"It helps us secure our applications from the build phase and identify the weaknesses from scratch."

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

"By using Nessus, we are able to finish testing with assured results, in half the time."

More Tenable.io Container Security pros

Cons

"Its technical support could be better."

"The configuration needs to be more flexible because it is difficult to do things that are outside of the ordinary."

"It doesn't have more advanced features like no false-positive security, which you can configure in Advanced WAF."

"The solution needs to be improved in the e-commerce portal."

"The setup of NGINX App Protect is complex. The full process took one week to complete."

"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 product's user interface is an area with shortcomings as it can be quite confusing for users, making it an area where improvements are required."

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

More NGINX App Protect cons

"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."

"The solution’s pricing could be improved."

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

"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."

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

"I feel that in certain areas this product has false positives which the company should work on."

More Tenable.io Container Security cons
