What needs improvement?
In general, the web interface is not really catchy. It's very powerful, very customizable, but it doesn't have a very nice GUI interface for a new adopter. For them, they'd have to do a lot of configuring. At least the reporting and monitoring parts, let's say, to be honest, should have a better interface. A few other products have very nice dashboards, out of the box, and F5 is not that friendly to use.
Also, when you buy WAF, you have to buy another module called APM to do authentication. You have to buy another module with an extra license, to have the authentication feature. Other vendors have it interwoven. For example, I don't know if Barracuda has it, but Citrix has it under the same license. So maybe add authentication functionality in the AOS license, and not separate.
For how long have I used the solution?
I've been using the solutions for 10 years.
What do I think about the stability of the solution?
The stability is perfect. 10 out of 10. We've not had any trouble with any deployment ever. And they are very big deployments: service providers, TelCos, banking, everywhere. Even on distant parts of the network, we have not had any kind of performance issues. Of course, as long as the sizing is within the appliance performance range. But it never has had a failure in performance or degradation of service or anything like this, as long as the full-time traffic is within the box capability, we've never had an issue.
What do I think about the scalability of the solution?
What other advice do I have?
We are a partner for F5, or a system integrator, not the client. So we do the implementation for other companies. I've been working with F5 for more than 10 years, so I know them very well.
I like them because I like the security solution. They get extra marks compared to other solutions or competitors. There are more features than any other product I can think of. They're always monitoring, and the security features offer more than other, lesser products.
I would rate this solution 10 out of 10.
