Executive SummaryUpdated on Oct 12, 2025

F5 Advanced WAF and Link11 are security solutions competing in the web application security category. F5 Advanced WAF has an edge due to its extensive feature set, though Link11's cloud deployment capabilities and support stand out.

Features: F5 Advanced WAF includes network detection intelligence, behavior analysis, and anti-bot protection with stable and reliable service. It allows for granular policy control and module integration for enhanced security. Link11 provides effective bot filtering and SQL injection defenses, coupled with customizable rule creation. However, it needs improvement in rule granularity and bot management.

Room for Improvement: F5 Advanced WAF's interface and reporting tools need enhancements for intuition and user-friendliness, along with better cloud integration and transparent pricing. Link11 should focus on improving its bot management databases and simplifying rule creation processes.

Ease of Deployment and Customer Service: F5 Advanced WAF supports diverse environments including on-premises and hybrid clouds, but its support is noted for mixed response times. Link11 is praised for its adaptability to cloud infrastructures and is known for responsive and reliable support, enhancing its reputation.

Featured Reviews

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

Cyber Security Consultant at ProTechmanize

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.

Offers flexibility with a kill switch for bypassing Reblaze if needed and provides a reliable Layer 7 defense against attacks

There is still some room for improvement when it comes to bot management from Reblaze because they are relatively new compared to other vendors in the town. AWS WAF, the Web Application Firewall from AWS, has a vast database of bad IP addresses due to its long-standing presence in this business. Reblaze, being a new entrant, is still building its database of bad IP addresses and malicious systems. So, Reblaze needs to work on that aspect. But other than that, I don't think scaling Reblaze has been an issue. There were some initial glitches, but they were all sorted out. So currently, I would say that the bot management and the database are areas they should focus on for further improvement.
