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.
Ahmed Moamen - PeerSpot reviewer
Protects applications with versatile authentication features
F5 offers a versatile solution that can be integrated with APM in cases where integration with an external IDB is needed. It is useful for authentication backup if the on-prem directory service is unavailable. Additionally, its WAF functionality is valuable for protecting applications from attacks. It is a versatile and strong solution that's easy to understand and deploy.
David Shlingbaum - PeerSpot reviewer
Simple solution and good WAF
Sucuri could provide help for specific security alerts in-line instead of requiring users to search for it in the help section. Users get errors or EBAs, and if they want to read about it, they need to find it in the help section of the site. It would be more helpful to allow users to see more information and tips immediately from within the alert.

Quotes from Members

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

Pros

"Cloudflare consolidates various capabilities into one product, streamlining processes."
"From what I've seen so far, there are no negatives to report as of yet"
"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"The solution offers the flexibility to control configuration rules."
"The features of Cloudflare were found to be more beneficial and led to the decision to utilize it over other options."
"Smaller businesses have seen great ROI due to the low investment and strong performance."
"It is a fast and secure DNS."
"It provides web application security and reduces bot attacks."
"F5 Advanced WAF offers features not available in other products."
"The support experience is better than average."
"In terms of F5 Advanced WAF's most valuable features, I would definitely say its stability. F5 is one the most stable products. Either as the load balancer or the web application firewall, it is very stable."
"Good technology for mitigating different application attacks, e.g. DDoS, DNS, and layer seven attacks."
"Feature-wise, they are always cutting edge and up-to-date. Many features aren't available via competitors. There's always a lot of enhanced critical features that just aren't available through anyone else, or, if they are, are too lightweight."
"F5 helped to meet compliance and regulatory requirements."
"The valuable features vary from customers to customers. Some customers are okay with the basic features of the WAF, and some customers use advanced WAF with a few other features."
"I use it as a WAF, which is basically a web firewall to monitor and block traffic to our web server."
"The initial setup was very easy."
"The initial setup was straightforward. Straight forward because the plugin can simply be installed and then it does its job. It's not complex, there is no learning curve. The online scan is simple, you put in the website address and the scan gives us a report on the browser itself. It's simple to use."
"It significantly eases the workload and streamlines the initial setup required to protect a website."
"The most valuable part is the analytics and visualization."
"Domain name scanning since it allows us to scan all our domain names and determine whether it has malware or if is reported as phishing."
 

Cons

"Support response time could be improved."
"Integration involving API with other products could be more user-friendly."
"The documentation could improve for Cloudflare DNS."
"The analytics, basically the dashboard, doesn't have much to it."
"The reporting can definitely be improved to offer a lot more explanation on something that may have happened or has actually happened."
"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."
"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."
"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."
"The interface is old-looking, it's not modern, which is why it's not always comfortable to use."
"Compatibility with multiple cloud environments needs improvement. Both stability and scalability need to be improved."
"The delay times on firmware patches and software updates could be better and improved."
"They should work on the virtualization of NGINX."
"F5 Advanced WAF could improve the reporting. It's a bit difficult to populate, them. If you're not so familiar with the functions, such as where to find the logs and other settings."
"I would like to see improved features in the F5 Advanced WAF solution, especially with a focus on enabling Kubernetes fully."
"F5 Advanced WAF sells perpetual licenses as perpetual assets during sales without informing me that support ends after a few years."
"The GUI interface can be confusing due to similar-looking tabs for policy building, traffic learning, and event logs."
"The main improvement I would like to see is support for .NET applications. If they could include this feature, I would include more sites in the protection."
"Sucuri could provide help for specific security alerts in-line instead of requiring users to search for it in the help section."
"It would greatly benefit customers if they implemented an online chat or messaging system for quicker assistance."
"I would rate this solution an eight out of ten. The reason is that we have found sometimes customers or Google saying that there is something wrong with the website but Sucuri says that the site is clean so we do have to look at the site manually which means that the Sucuri scan does not pick up anything and everything."
"Confident score: Currently it does not have one and there are cases that most websites flagged are false-positives."
"In terms of improvement, the cost factor is always there."
 

Pricing and Cost Advice

"The cost primarily depends on the size of the organization."
"The product's pricing is minimal compared to other products."
"In terms of licensing costs, we don't pay for licensing for Cloudflare. We only establish communication, then for peering, Cloudflare takes care of the cross-connection in different data centers."
"We are using the free tier of the solution."
"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"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 pricing is too high."
"F5 Advanced WAF technical support comes at a cost, and it's expensive."
"The pricing of F5 Advanced WAF is more expensive than other solutions like Radware and CD18, it is quite high."
"There are different licenses available to use F5 Advanced WAF, such as BT, ASM, and LPM."
"It is a little bit costly, but it has all the features that are required."
"F5 Advanced WAF is not a cost-effective solution. Although they are attempting to reduce prices with their VE and cloud options, they are more expensive than other solutions. The solution is more expensive on average."
"The solution is very expensive so should only be used in the right environment."
"I would rate the pricing as seven out of ten"
"I’d simply say it’s really worth it."
"Sucuri offers different plans, both the standard plan and an advanced plan. So there are different plans to choose from."
"It stands out as a more cost-effective option compared to other cloud-based security services like Cloudflare or JetPass."
"The ROI has been very good. Because of the solution, I have a tax break. The site developers were not always experienced people. We used to pay more for cleaning up the site when it was infected. Now, we have peace of mind knowing that the solution will clean up the site and that we won't have to go through the unnecessary process of restoring it from a backup. The protection on the WAF and the measures for backups have also prevented our site from going down."
