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 web application firewall itself is most valuable. It provides positive security and negative security. In negative security, it blocks a task such as cross-site scripting, code injection, etc. In positive security, it lets you specify and enforce things, such as the parameters allowed in username and password fields and the number of characters allowed in a field."

"The whole mechanism of F5 Advanced WAF is effective."

"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."

"F5 Advanced WAF helps our engineers to learn the complete configuration, including fundamental and advanced policies."

"The most valuable feature of F5 Advanced WAF is its extensive set of capabilities for application protection, including DDoS prevention, and its ability to work with Pentesters and external scanners to observe user activity and eliminate false positives."

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

"This solution inspects your traffic and based on that, automatically create distinct qualities for you, so you can add this to the policy already created. That's what I like most."

"The solution's most valuable features include application DDoS protection, bot blocking, and HTTP header verifications."

More F5 Advanced WAF pros

"Its initial setup process is straightforward."

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

"Fastly provides CDN, WAF, image optimization, and IP restriction."

"Compute@Edge features are valuable to me."

"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."

"Support is good; the product works as advertised. We have a Slack connection with them. So we can basically ask for help, live, engage, and ring when they respond. Very quickly."

"Rate limiting is a good feature that protects from volumetric attacks."

More Fastly pros

Cons

"I would say their graphical interface, the GUI. I don't like the GUI as much as before."

"I think the most significant improvement needed is reconsidering the price, as it is really expensive compared to other vendors."

"The tool needs to improve its pricing."

"F5 Advanced WAF could improve the precision of the scanning. There are many false positives. They should improve their threat database."

"F5 Advanced WAF could improve resource usage, it is CPU intensive. Additionally, adding automated remediation would be a benefit. For example, an easy button alerts us of the events that are occurring, and what we want to do at the time. An automated approach where somebody could be alerted very quickly. Instead of going and reconfiguring everything, an automated approach is what I'm looking at."

"For me, an area for improvement in F5 Advanced WAF is the reporting as it isn't so clear. The vendor needs to work on the reporting capability of the solution. What I'd like to see in the next release of F5 Advanced WAF is threat intelligence to protect your web application, particularly having that capability out-of-the-box, and not needing to pay extra for it, similar to what's offered in FortiWeb, for example, any request that originates from a malicious IP will be blocked automatically by FortiWeb. F5 Advanced WAF should have the intelligence for blocking malicious IPs, or automatically blocking threats included in the license, instead of making it an add-on feature that users have to pay for apart from the standard licensing fees."

"One area for improvement in the product is its SSO integration, which posed challenges and required significant effort to resolve."

"The solution could improve by having an independent capture module. It has a built feature that you can deploy the capture on your published website. However, it's not very user-friendly. When you compare this feature to Google Capture or other enterprise captures, they are very simple. It needs a good connection to the F5 Advanced WAF sandbox. When you implement this feature in the data center, you may suffer some complications with connecting to the F5 Advanced WAF sandbox. This should be improved in the future."

More F5 Advanced WAF cons

"Fastly's customer service area needs improvement."

"The solution's pricing could be better."

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

"Support is not that great."

"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."

"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."

"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."

Pricing and Cost Advice

"It is expensive. Its price should be better. Its licensing is on a yearly basis. Its licensing is also based on the model. There are no additional costs."

"The way we deployed it, I would rate it a four out of five in terms of pricing."

"I don't have any issue with the pricing of this solution."

"As far as the pricing of F5 Advanced WAF I would rate it a four out of five depending on what features I am looking for. Imperva is more expensive."

"I am not sure about pricing but licenses are available on Google."

"I would rate the pricing as seven out of ten"

"Pricing for this solution is higher than average."

"There are various plans available for Fortinet FortiWeb Cloud WAF as a Service, including a trial version."

More F5 Advanced WAF pricing and cost advice

"The solution is cheaper than other products in the market."

"It is an expensive solution."

"Fastly is less expensive than one of its competitors."

"I've generally found Fastly to be very competitive in pricing, especially around Compute@Edge."

"In my opinion, Fastly is priced competitively."

"The pricing has been very competitive."

"You need to pay a premium price for the tool."
