Featured Reviews

Carlos Alam Hernandez Baruch - PeerSpot reviewer
Fast and secure deployments simplify operations for government and fintech clients
It is a fast and secure DNS. It is very easy to deploy, and my customers are happy with this tool. Additionally, the CDN performance in Mexico is excellent, providing fast service and tools. It offers reliability during high-traffic periods, ensuring no impact on the environment. It helps my clients avoid using on-premise boxes, simplifying operations as they only use the prices on Cloudflare.
Carlos Alam Hernandez Baruch - PeerSpot reviewer
The solution enables seamless security management and fosters a learning environment
Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions. For the solution stopping us for e-learning, I appreciate the concept yet need more resources or courses in Mexico, preferably in Spanish. Certifications are easy, however, I require more real-world environments and instructors.
Pawel Augustyn - PeerSpot reviewer
Provides outstanding resource management and application security across multiple geographies
The most valuable features for me are stability, availability, and security, along with the ability to manage multiple features to secure my applications. The solution also monitors and blocks unconventional requests and maintains security efficiently. The scalability feature also allows me to manage and allocate resources dynamically without disrupting production traffic.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It's very user-friendly."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"The most valuable feature of Cloudflare is that it has a free version. They give us the free version with the anti-DDoS features and also the load balancing solution."
"I get a lot of value from Cloudflare's API because it enables you to build a separate environment inside the solution. You can create a domain for performing test requests before you move to the production environment and connect various domains."
"The most valuable feature is its usability."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."
"The best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."
"Enables me to work from two locations."
"It will take the blow rather than our applications should an attack occur."
"Cloudflare, in my opinion, was easy to implement."
"The solution has different options that can be used to differentiate DDoS attacks."
"Clover is the best product globally."
"Cloudflare Access is part of the Zero Trust philosophy."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"The most valuable features of F5 BIG-IP Advanced Firewall Manager (AFM) are the web gateway, load balancing, services, and applications available."
"I find the signature base is very helpful to see traffic"
"The product’s most valuable features are LTM and WAF."
"The features of F5 BIG-IP Advanced Firewall Manager that have proven most effective in securing the network are significant."
"The setup and functionality are fairly straightforward."
"It excels in preventing downtime and maintaining application performance, which is crucial for our clients' security and operational continuity."
"CGNAT is one of its strong areas."
"The most valuable feature of F5 BIG-IP AFM is the iRules where I can customize the configuration."
 

Cons

"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"Cloudflare should add more documentation and pricing to the cloud version."
"It would be beneficial for us if Cloudflare could offer a scrubbing solution. This would involve taking a snapshot of my website and keeping it live during a DDoS attack, ensuring uninterrupted service for our users. DDoS attacks are typically short in duration, and having Cloudflare maintain the site's availability from its secure network would enhance the overall user experience. I would appreciate it if Cloudflare could consider implementing this feature. Many organizations already utilize similar capabilities in their CDN platforms, where a static snapshot of the web page is displayed during DDoS attacks. In terms of features, Cloudflare needs to enhance its resilience and stay more focused on adopting new technologies. For instance, solutions like F5 XC Box, Access Solution, and Distributed Cloud Solution have impressive features, and Cloudflare should strive to match and exceed those capabilities. There's a need for improvement in areas like AI-based DDoS attacks and Layer 7 WAF features. Cloudflare should prioritize enhancements in areas such as behavioral DDoS and protection against SQL injection attacks, considering the prevalent trend of public exposure to the internet for business reasons. Overall, Cloudflare needs to invest more in advancing its feature set."
"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."
"Technical support is lacking."
"There could be more courses with engineers. I like e-learning, however, having a specialist in a classroom is more comfortable for me."
"The product support needs to be accessible from more places, a wider area of coverage."
"The timing aspect can lead to it being considered overpriced. This is a particular concern we have with Cloudflare, as they may struggle with accurately detecting the client."
"They don't have a person to provide support for customers using the solution under their free plan."
"The initial onboarding was causing us some confusion."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"For the topic of improvement, providing some training material is one of my suggestions."
"The response time for support must be reduced."
"Our customers no longer use Cloudflare because its service is subpar."
"Cloudflare Zero Trust Platform needs to improve its documentation. It took time to do the implementation."
"Operating and tuning the product is difficult."
"Apart from the price, I feel no other areas need improvement."
"F5 BIG-IP Advanced Firewall Manager's pricing and technical support services need improvement."
"For configuring the firewall, every single vendor on the planet has pretty much the same logic when it comes to firewalls, and F5 has a completely different approach and completely different behavior."
"The web gateway feature could improve in F5 BIG-IP Advanced Firewall Manager (AFM)."
"The product is expensive."
"Deployment times vary according to the customer. It needs to be heavily configured. You need to look and you need to observe the behavior of the traffic before you can start configuring everything. It can take time."
"The initial setup of F5 BIG-IP AFM in a complex environment was simple. However, the full deployment took us approximately one year."
"F5 BIG-IP AFM can improve the reporting interface in relation to advanced troubleshooting depending on CLI. They should have enhanced troubleshooting with the use of GUI."
