F5 Advanced WAF and Link11 compete in the web application firewall category. Based on features, Link11 appears stronger in automated monitoring and region-specific threat management, while F5 Advanced WAF offers versatile and detailed threat detection. In areas of improvement, Link11 focuses on simplifying rule creation, while F5 Advanced WAF has complexities in integration and pricing.
Features: F5 Advanced WAF features robust network detection intelligence, behavior analysis, and advanced threat signatures, known for its stability and flexible security configurations. It also provides comprehensive attack signatures. Link11 emphasizes real-time monitoring, botnet defense, and API security, excelling in geographic threat management and region-specific traffic defenses.
Room for Improvement: F5 Advanced WAF users report complexity in its user interface and reporting system, integration challenges, pricing, and CPU intensity, requiring advanced knowledge for optimal deployment. Link11 should focus on enhancing rule creation simplicity and strengthening its threat intelligence database.
Ease of Deployment and Customer Service: F5 Advanced WAF supports hybrid and on-premises deployment, with strong but sometimes slow customer support. Link11 offers a flexible, cloud-centric deployment and receives praise for direct and international support access.
Pricing and ROI: F5 Advanced WAF is seen as a premium solution with significant ROI justified by comprehensive security in enterprise-grade settings. It involves higher upfront and ongoing costs. Link11 offers predictable costs with flexible, negotiated pricing scenarios, a cost-effective option for early-stage investments or scalable needs.
Time savings in daily operations come from the automatic learning and signature update reducing the need for constant manual rule management, allowing the security and network teams to spend significantly less time handling false positive application-related escalations.
Subscription models offer clearer ROI due to a more competitive pricing scheme.
The amount of attacks it protects against is immense, more than F5 Advanced WAF itself costs.
Both response time and availability need to be improved.
While they resolve issues well, the time taken for responses to non-critical issues should be shorter.
If there is a bug, the support is usually understanding and resolves issues.
If you need to scale up, such as moving from a lower model to a higher one, the configuration from the lower model can be migrated easily without issues.
I can run it in HA mode or even divide the traffic volume to the number of instances that I have based on their resource sizing.
F5 Advanced WAF has been very reliable and consistent for us; in our on-premise enterprise setup, it has been stable and predictable in day-to-day operations without any unexpected crashes or WAF-related downtime in production.
F5 Advanced WAF is stable, and there is no doubt it is one of the best WAFs in the market.
F5 Advanced WAF is pretty stable.
Deployment training for F5 Advanced WAF is lacking and restricts growth by being inaccessible and costly for partners.
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.
Another improvement could be refining the bot detection to minimize false positives; it should be able to verify more granularly between legitimate and non-legitimate clients.
Licensing is capacity-driven, so you need careful planning based on traffic volume and use cases, and adding features such as Bot Protection impacts costs; once licensing is clear and sized correctly, there are no surprises.
Subscription models have competitive pricing, while perpetual licenses involve an upfront higher cost.
The price is affordable and satisfactory.
The Advanced Attack Signature database is very strong and regularly updated, effectively blocking SQL injections, cross-site scripting, command injections, and file inclusion attacks while allowing selective enabling or disabling of signatures to avoid blocking genuine traffic.
The perpetual license, despite an initial higher cost, lacks transparency regarding support expiration.
It contains the logic of both negative and positive security combined.
