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.
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.
ShashikaKodikara - PeerSpot reviewer
A solution requiring straightforward maintenance while remaining cost-effective compared to its competitors in the market
I am not in a position to speak about the areas where the solution needed improvement because I resigned during the implementation phase. At that time, the implementation was ongoing, and everything seemed to be going well. Using the solution, our team managed to transfer a couple of routers through a few areas. However, I believe the migration is still ongoing. Nonetheless, the first phase of the implementation was successful before my departure. There was a certain level of performance degradation in the solution, which I don't know if it can be tuned. This is because I was working for a short period on the solution. In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution. If one wants to scale up, then one needs to change their plan. However, the thing is, one can always go for the larger scale based on one's anticipation of future traffic.

Quotes from Members

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

Pros

"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 most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"The overall experience with Cloudflare is positive, with a rating of eight out of ten."
"The most valuable feature is its usability."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"The web application firewall brought us good security and a view of the accesses/blocks of the entire domain and subdomain that were accessed both by region (country) and IPs."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"The solution provides behavioral analysis via AI to detect malicious traffic."
"It blocks various attacks and mitigates disasters from occurring."
"The protection is very useful."
"The most valuable features of F5 BIG-IP Advanced Firewall Manager (AFM) are the web gateway, load balancing, services, and applications available."
"The decryption is great."
"The most valuable feature of F5 BIG-IP AFM is all of my workers enjoy using it."
"This product excells in every aspect from installation and the interface to providing superior network security."
"The features of F5 BIG-IP Advanced Firewall Manager that have proven most effective in securing the network are significant."
"The support team was helpful."
"Filters can be customized depending on the characteristics of the attack traffic. This feature has made it easier for Nexusguard's SOC team to further isolate any specific attack that can't be blocked by pre-configured mitigation."
"The managed service allows us to confidently rely on Nexusguard’s professional team to take relevant actions as and when required to make sure DDoS attacks are successfully mitigated, ensuring 100% uptime of our service."
"Cloud Diversion is another good feature packaged with the whole solution. When attack traffic is detected, Cloud Diversion triggers to automatically route our prefix to Nexusguard’s scrubbing center, ensuring that all attack traffic is dropped in the shortest time possible."
"Based on the support received for implementation, I rate the solution's technical support a nine out of ten."
 

Cons

"It should have easier documentation for the configuration. It's very technical and people who aren't technical should also be able to do the configuration."
"Technical support is not well developed. While there are good engineers, Cloudflare does not offer hands-on technical support to fix customer problems but rather a self-service model."
"For large enterprises, the pricing is okay. However, the enterprise price for small projects is a bit high. A mid-tier pricing option would be beneficial."
"The tool needs to improve caching of servers. The product needs to include PFX certificate as well."
"The pricing could be improved."
"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."
"The solution could be more user-friendly."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"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."
"NGINX, which F5 purchased, has room for improvement in its features, particularly its load balancing or application load balancing features."
"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."
"Apart from the price, I feel no other areas need improvement."
"There should be simplified and better integration with BIG-IQ."
"We would have preferred to have support when we first started"
"The solution’s initial setup is not easy."
"Some spam can go by the firewall."
"One of the features that should be added to the next release is report generation. Currently, reports can be downloaded every month and are only available at the beginning of each month. It would be nice to generate the reports based on specific dates that we prefer and not have to wait until the next month for the current month’s report."
"One thing that we would like to improve from them is to provide more training to SOC team for them to have a deep understanding of the solution so that they would always be ready to answer anything without the need to escalate queries to senior personnel."
"There was a certain level of performance degradation in the solution, which I don't know if it can be tuned...In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution."
"The mitigation scope of Origin Protection is not fully efficient as there could be delays in activating the countermeasures."
"The solution must provide features for the post-processing of the traffic type and the traffic quality."
 

Pricing and Cost Advice

"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The price is reasonable."
"For Cloudflare, I recommend it heavily for small businesses with revenue under a couple of million dollars. Onboarding is easy, and they even have a free plan. This makes it simple for businesses in the $100,000-$500,000 range to try it out and see its value, allowing them to scale up their infrastructure as needed."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."

"The product's pricing is minimal compared to other products."
"It's very expensive, and you pay extra for the models."

"As per pricing, I would not say cheap, but little higher than cheap, but not very expensive. So you can say kind of value for money solutions."

"The price of F5 BIG-IP AFM is a little more expensive than other firewalls on the market."
