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.
Pricing and ROI: F5 Advanced WAF is considered expensive with high licensing and support costs, yet it offers substantial ROI for enterprise-level protection. It helps prevent revenue losses and maintains compliance. Link11, on the other hand, offers balanced pricing with predictable costs, making it a cost-effective solution despite higher initial investments.
For the small project I was working on, using the basic tier provided a huge improvement at zero cost.
In terms of return on investment with Cloudflare, it costs my time to set them up, but basically once they're set up, it's done.
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.
F5 Advanced WAF protects our organization and provides security, achieving a return on investment.
Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model.
I would rate the technical support with Cloudflare as excellent every time I've had to call them.
I have primarily worked not with the tool's customer support but with the product's sales engineers and technical sales engineers, who seem to know their stuff.
Both response time and availability need to be improved.
F5 Advanced WAF provides the insights and notifications I need in terms of reporting and alerting.
If there is a bug, the support is usually understanding and resolves issues.
It is a SaaS tool, but the fact that they have workloads deployed across the world proves that it is a highly scalable tool.
The tool offers very good performance, even during high-traffic periods.
I rate the solution’s scalability an eight out of ten.
I rate the solution’s stability an eight out of ten.
The service is very stable with no impacts during high-traffic periods.
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.
Despite these challenges, overall, Cloudflare remains the preferred solution compared to Azure, AWS CloudFront, and Google Cloud Armor.
Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements.
There are some performance considerations when it comes to dynamic content that involves fetching data from databases or using APIs.
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.
There is excellent clarity in the LTM and the WAF.
I find it to be cheap.
I rate the product’s pricing a five out of ten, where one is cheap, and ten is expensive.
The tool is a premium product, so it is very expensive.
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 most valuable features of the solution are performance and security.
Techniques like minification and image compression reduce the size of assets, leading to better performance and faster user load times.
The solution has been able to compare it to the market, and I think the product has taken great strides in automating quite a bit of things, and they use a lot of AI.
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.
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.
