Citrix NetScaler and F5 Advanced WAF compete in the application delivery and web application firewall sectors. F5 Advanced WAF seems to have the upper hand due to its advanced security features and stability, which are highly valued by users.
Features: Citrix NetScaler offers flexible deployment, seamless integration with Citrix products, and robust features like load balancing, SSL offload, and global server load balancing. Users find it ideal for virtual environments and appreciate its ease of configuration and competent technical support. F5 Advanced WAF provides advanced threat detection, DDoS mitigation, and API security. Its stability and comprehensive attack signature capabilities are crucial for users focused on security.
Room for Improvement: Citrix NetScaler users suggest enhancing feature innovation and simplifying the UI. There is dissatisfaction with configuration complexity and frequent changes, with calls for better documentation and responsive technical support. F5 Advanced WAF users indicate a need for improved integration, enhanced reporting, and simpler configuration. They also seek more user-friendly interfaces and better support service responsiveness.
Ease of Deployment and Customer Service: Citrix NetScaler supports various deployment environments including on-premises, private and hybrid clouds. Technical support feedback is mixed, with prompt assistance and delays both noted. F5 Advanced WAF is deployable in similar environments, typically in hybrid settings. While it has a robust support structure, users express concerns about customer service response times and expertise.
Pricing and ROI: Citrix NetScaler is often seen as costly compared to competitors, praised for performance and feature set but seen as expensive for smaller businesses. Despite the cost, users report favorable ROI due to stability and integration capabilities. F5 Advanced WAF is also known for higher pricing, justified by users due to its significant protection features, although its cost remains a barrier for smaller enterprises. Users report a positive ROI, driven by robust security and advanced functionalities.
A large volume of malicious traffic was blocked at the WAF layer, preventing issues from reaching the backend servers, which reduced emergency troubleshooting and application team involvement, ultimately lowering operational stress and incident cost savings without requiring additional security tools.
Subscription models offer clearer ROI due to a more competitive pricing scheme.
F5 Advanced WAF protects our organization and provides security, achieving a return on investment.
F5 Advanced WAF provides the insights and notifications I need in terms of reporting and alerting.
Both response time and availability need to be improved.
If there is a bug, the support is usually understanding and resolves issues.
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.
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.
Whenever something goes wrong or we have to whitelist anything, it clearly indicates where to go and where I have to make modifications.
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.
After implementing F5 Advanced WAF, we saw a significant reduction in web-based attacks such as SQL injection, cross-site scripting, and automated malicious traffic, allowing us to block real threats before they reached the backend server.
F5 Advanced WAF offers the best features that are capable of stopping any type of attack, and it is a really reliable and stable product that you can rely on to stop any type of attack.
The perpetual license, despite an initial higher cost, lacks transparency regarding support expiration.
