Senior Information Security Engineer at a tech company with 10,001+ employees

Advanced policies and web firewall have strengthened application protection and reduced attack traffic

There were some vulnerabilities in F5. They tried to fix it, but the fixes were not available at the time because they were zero days, so they attempted to fix it, but their support was not proper. Their support should be improved because sometimes features which we need for customization take time, and they are sometimes feasible and sometimes not feasible by the team, so their support and the engineering team should improve their product. I would like to see more features regarding customization which should be built into the application, and the tool optimization should be good, and the dashboard should be more crisp and clear.

Quotes from Members

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

Pros

"Its versatility and capabilities make it invaluable for implementing patches and fixes when necessary."

"The primary valuable feature of NGINX for me is its ability to provide a reverse proxy."

"This is a great product, it has everything."

"Nginx is extremely efficient in terms of the connection rate to the CPU cycles ratio, and in terms of the bandwidth to CPU cycles."

"Zero Downtime has always been a strength in recommending infrastructure web services, and NGINX allows me to execute such infrastructure with less complications and the ability to switch from server to server easily."

"Nginx is simple to configure, very stable in a highly utilized environment and very modular, allowing DevOps to create it's own modules for interactive use with Nginx."

"NGINX provides a cost advantage, value addition, and effective support."

"Application Gateway with application-level firewall tool and load distributor and balancer (also serves for A/B testing)."

More NGINX Plus pros

"Zend Engine is the core of PHP. It makes PHP fast, efficient, and basically, the language of choice for web applications."

"The solution's initial setup process is easy."

"The fact that it is available open-source is the best feature."

"We have not encountered issues with scalability as long as we effectively use caching to optimize performance of our web applications as well as a proper use of database connectivity."

"It offers good support for various types of classes, along with many open source libraries that we can readily utilize in our application development process. This gives us a lot of options when it comes to custom development solutions, without having to worry about licensing or other programming-related issues."

"No issues with stability encountered."

"The Zend Framework provides an easy, open source way to produce coding based on the needs of our customers."

"The cache modules that Zend provides have been able to optimize and accelerate the loading of the pages when there was exponential growth in data volume and quantity of requests. At the same time, the monitoring console allowed us to have a real-time understanding of the resources and to make decisions when they were at the limit."

More Zend PHP Engine pros

Cons

"I am not so happy with their pricing policy, but this is not the worse thing in my life."

"The user interface could be improved."

"Our most challenging part was to run an older PHP website reverse-proxied through NGINX. That was not fun."

"The KPI on NGINX Plus should be more focused on load balancing and the latency in application calling from the end system."

"Instance service health check on the NGINX load balancer feature could be improved."

"Make modules easier to enable or disable. The beauty and ugly side of the NGINX modules is you have to know how to compile the module. For beginners or non-very technical aspirant(s) going for NGINX, they have to learn how to compile the modules."

"Only improvement needed that I would point to is scalability. With it, I mean clusterized organisation on a low level. At the moment, the best alternative is RHEL HA."

"They tried to fix it, but the fixes were not available at the time because they were zero days, so they attempted to fix it, but their support was not proper."

More NGINX Plus cons

"The process of installing and configuring the product is a bit complex and could be improved."

"Integration of MVC with ORM tools for PHP is okay, but lacking a short list of decent ORM tools for PHP to choose from; there is ample room for improvement in both areas."

"Integrating AI tools would make PHP more competitive, as other tools already have AI features."

"The platform is not satisfying to me -- it is just not up to standards performance wise."

"In terms of improvement, it doesn't support concurrent processing. When we want to process anything on a concurrent basis, we have to divide it into a number of things, like a queue, or we have to run it using Cron jobs. We would like to have the capability to run any thread or process in parallel."

"The solution can be quicker."

"The main area that Zend needs to improve is to support asynchronous programming tasks, which is facilitated in PHP 7, but not at the same degree as HHVM."

"SQL queries have always been an issue with PHP, especially if you use large tables, which require caution from the side of the developer."

More Zend PHP Engine cons

Pricing and Cost Advice

"The list price of NGINX Plus is close to $5,500."

"I use the solution's community edition which is free of cost."

"The cost is reasonable."

"I am not so happy with their pricing policy, but this is not the worse thing in my life. I can tolerate it."

"You pay for each feature that you want."

"The solution is free, but you can spend a lot of money with a complex solution."

"It's an open source solution, so it's free."

"NGINX is a free tool in Brazil. There are some companies which do support it."

More NGINX Plus pricing and cost advice

"No problem with pricing and licensing, as tools are open source. You have to consider training cost, mindset setup cost, as part of the TCO."

"The solution is open source and you just pay for the server cost."

"Zend PHP Engine is not an expensive solution."

"Its pricing depends on the number of users."

"The Zend PHP engine is open source technology, so there's no need for us to worry about licensing or other costs."
