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

"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"I like Cloudflare's application gateway and DDoS protection."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"Centralized, full-featured DNS."
"The most valuable feature is its usability."
"It will take the blow rather than our applications should an attack occur."
"I'm very satisfied with the environment and the dashboard."
"Cloudflare is by far the most effective solution that I have come across."
"The capabilities of the software are strong enough for me to do what it's supposed to do. For me, we don't need to do a lot of configuration on our site. We just enable it and monitor it."
"Cloudflare DDoS mitigates DDoS attacks."
"It's the endpoint exposition. We don't need to expose our VPN server to the internet and need a zero-test solution. I can apply some conditional access to the endpoint that's connecting to our network to check their security policies or the security condition of their workstation. Once the workstation is trying to connect to my internal network, then I would like to check the discrete condition of these endpoints that are trying to access my internal network. We created some conditional access. We have CrowdStrike, to check if the CrowdStrike is installed, to check if it's updated, and to check for Windows updates. We created some conditional policies to check it."
"For Cloudflare Access, I am using the free plan...The most valuable feature is their protection."
"Cloudflare Access is part of the Zero Trust philosophy."
"The customer service is excellent, and I rate it ten out of ten."
"It blocks various attacks and mitigates disasters from occurring."
"The setup and functionality are fairly straightforward."
"The most valuable feature of this solution is that the blocking of IP's."
"It is stable."
"This product excells in every aspect from installation and the interface to providing superior network security."
"The protection is very useful."
"It excels in preventing downtime and maintaining application performance, which is crucial for our clients' security and operational continuity."
 

Cons

"I would like Cloudflare to offer a dedicated account manager for large enterprise clients like us."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"Even if I wanted to, I wouldn't be able to buy Cloudflare in my country."
"Cloudflare doesn't have a reverse lookup. We can only do a DNS lookup to get the IP address from the hostname. It doesn't work if you want to look up the hostname from an IPA address."
"Eventually, things go sideways and require fixes when it would have been easier to prevent the issue initially."
"There should be a specific price list for enterprise-level customers."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"The software has automated alerts, but the automated alerts are not available in the mobile app."
"Cloudflare DDoS has poor technical support."
"There are premium tier live service and lower tier live service, so we opted for the lower tier. But there is no medium tier where we pay a little extra and get a bit more service. So if that can be improved."
"Our customers no longer use Cloudflare because its service is subpar."
"For the topic of improvement, providing some training material is one of my suggestions."
"The tool should provide on-premise versions. Currently, all versions are cloud-based."
"The free plan has limitations. For example, I can only set up three rules, and the application firewall is unavailable."
"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."
"We needed to protect the database but the solution didn't offer a certain feature to do so."
"F5 should increase its capability to prevent zero-day attacks."
"We would have preferred to have support when we first started"
"Firstly, geolocation currently relies on manual updates. It has to move to automatic updates. There are no automatic updates for this feature. If some IPs, countries, or service providers move to another country, now you will be allow IPs that you previously denied. This is because you depend on the database, which doesn't update automatically. This is really a very important area that they need to improve."
"The web gateway feature could improve in F5 BIG-IP Advanced Firewall Manager (AFM)."
"The appliance and features could be enhanced further, especially in terms of security. Some features like the WAF firewall may seem expensive compared to the standard license, so there could be room for adjusting the pricing."
"F5 should increase its capability to prevent zero-day attacks. Having advanced technology similar to other vendors like Palo Alto for zero-day attack prevention would be valuable."
"Some spam can go by the firewall."
 

Pricing and Cost Advice

"The cost primarily depends on the size of the organization."
