Application security has protected critical banking services while policy learning minimizes false blocks

F5 Advanced WAF performs well overall, but I have noticed some points that could enhance the solution. Initially, policy tuning could be simpler, as while the learning engine is powerful, initial tuning still requires experienced engineers, which can be challenging for new teams due to the complexity of options and parameters. A more guided and simple tuning workflow would help reduce the learning curve. Additionally, tighter native integration with SIEM or SOAR tools would simplify correlation and investigations for security teams, although log exports are available. Overall, these are not blockers, merely enhancement opportunities, and once tuned, F5 Advanced WAF is very stable and reliable; improving usability, reporting, and onboarding would make it even more effective for larger environments.

Optimized ecommerce performance and improved access control through image handling and IP filtering

I believe that Fastly should provide guidelines for their WAF blocking rules. It should be public what the rules are that are blocking their contents. I believe Fastly should provide regional IP addresses instead of POP IPs. Fastly should provide features similar to Cloudflare regarding a block list. Additionally, a POP address should be there with a wide range of IP addresses provided, public static IP addresses, so customers can integrate egress IPs. Fastly should provide WebP image processing on the backend instead of on the fly. It would be a very useful feature to avoid unnecessary time for browser to browser and local cookies. I believe that Fastly service has a few gaps. We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers. There should be transparency.

Quotes from Members

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

Pros

"The bot defense capability, as well as protection from brute force attacks and OWASP Top Ten, are notable features."

"The solution uses AI to protect against botnet attacks."

"The product is used to secure web applications and has the ability to use API templates and bot protection features, such as blocking requests or presenting CAPTCHA pages to end users."

"It is easy to obtain dashboard compliance because security policy views are included."

"Feature-wise, they are always cutting edge and up-to-date. Many features aren't available via competitors. There's always a lot of enhanced critical features that just aren't available through anyone else, or, if they are, are too lightweight."

"My favorite feature of F5 is the ability to play around with the ciphers. I also like the ability to have an immediate display of the support IDs when a real blockage occurs. The protection offered is great."

"It also has antivirus and DDoS mitigation capabilities. We have enabled these features."

"Overall, I believe it has been a good decision to switch because I do not think any other product available on the market can compete with F5 at this time."

More F5 Advanced WAF pros

"The product helps our organization to access sites located in different regions quickly."

"Fastly uses configuration versioning, where you can deploy a new version in less than one minute."

"Fastly combines both the CDN side and the Signal Sciences next-generation WAF, which is closely integrated with the CDN, allowing us to use both products seamlessly."

Cons

"I would like to see the API Protection improved."

"The delay times on firmware patches and software updates could be better and improved."

"The deployment side is quite complex."

"I would like for there to be a cloud-based solution, this would also help to improve scalability."

"One improvement for AOF could be focusing on enhancing its AI engine to make it more mature."

"Most customers encounter stability issues with the product's Big-IP logs."

"The reporting portion of F5 Advance WAF is not great. They need to work out something better, as it is very basic. You only see the top IPs, I think there is more they can offer."

"Users would like to have an additional IP intelligence license to handle this within WAF itself without needing to engage with the SOC team."

More F5 Advanced WAF cons

"The solution's pricing could be better."

"Support is not that great."

"Stronger analytics would be helpful, like showing configurations that haven't served a certain amount of traffic in a while. With many properties, things can get lost track of - duplicates or unused configurations not properly decommissioned."

"What I don't like about Fastly is that they charge a heavy price."

"It is missing a "staging" platform to deploy a test configuration with all of the real settings, which would allow us to properly test before putting it into production."

"Fastly's customer service area needs improvement."

"We are not getting quick responses from Fastly technical support engineers. Sometimes they depend on their D3 developers."

"The product should provide improved bot detection and management."
