Advanced security reporting has protected high-traffic betting platforms from constant attacks
I don't see room for improvement to Cloudflare Web Application Firewall. One thing I don't know much about because we have a dedicated IT team for that, and I'm not involved with Cloudflare much anymore. But if I were to compare them to F5, I would like to see more features that F5 offers. F5 has an option to bring the whole infrastructure, the whole WAF and all their packages, Bot Management, and everything else on your infrastructure. You need to install certain services from their side, and then you can choose if you would like requests to hit your servers immediately or if requests need to be proxied through F5 backbone. That would be a nice addition because we have 90% of the traffic as legit traffic coming from whitelisted servers. If it comes from whitelisted servers, I don't need to go every request through the backbone; I could easily just IP whitelist everything. Then I could maybe have Bot Management on my infrastructure that drastically reduces the price of Cloudflare. I would like to see Push CDN more improved in the next release of Cloudflare Web Application Firewall. And maybe something similar to Pushpin that Fastly has, which is an option where you can push messages that then can be scaled globally over the network. From our perspective, if we have a listener that listens for stock updates, I would just need to have one processor that pushes those updates to the Cloudflare API, and then Cloudflare would broadcast that message to all listeners. Cloudflare will check the order of the message, and if you, as a customer, are not connected or have some kind of network issue, when you reconnect, you will receive the latest state and missing updates.

Granular security policies have protected critical applications and ensure safe user and admin access
Improvements could be made regarding the log information from the backend CLI. There are enhancements needed; if a request gets blocked on the TCP layer, there should be traces or data to verify which source generated these requests, including the source and port information for initiation. These data are missing from F5 Advanced WAF. Besides that, another improvement could be refining the bot detection to minimize false positives; it should be able to verify more granularly between legitimate and non-legitimate clients. Overall, I find everything else good. A wish list feature I have is for the Technical Assistance Center (TAC) to respond more promptly. Their response time needs improvement; while they do not take excessive time, it can be enhanced, especially given it is a security product.

A cost-effective choice for website security and informative support with issues related to CDN quality
One area where they could improve is in providing real-time support options because now you need to open a support ticket and wait for their response. It would greatly benefit customers if they implemented an online chat or messaging system for quicker assistance. I have found their Content Delivery Network service to be lacking in quality, and it could certainly be enhanced to provide better performance. I would also like to see improvements in the deployment process, as it currently takes more time than desirable. Another significant concern is that their service when your website is down, turns it into a static site. This means that if customers try to visit your site during downtime, they will see old content from the static site, which is not ideal. The CDN and tracking services are areas that need improvement, as well as addressing their bandwidth limitations.

Quotes from Members

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

Pros

"The integration of Cloudflare with Cloud Suite is its most valuable feature."
"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."
"The Cloudflare Web Application Firewall's most valuable feature is its ease of configuration."
"I have not had any issues with this solution, and I would recommend it to others who are interested in using it."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"It is a SaaS solution unlike much of the competition."
"Cloudflare has positively impacted my organization by making it easier for me to handle and set up DNS for multiple clients; I can easily go in and access their accounts, make changes they need, and it's a one-stop shop."
"This is a good product; it's reliable and scales well."
"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."
"What a WAF is happens to be exactly what we are using F5 WAF for: a firewall for our web applications."
"Identification, ease of use, and ease of modifying it to most of our needs are valuable."
"I would recommend this solution because it is overall a very good solution."
"The most valuable features of F5 Advanced WAF are the security features and the protection."
"F5 Advanced WAF is a stable solution, we are satisfied. It is more stable than ForiWeb."
"The solution isn't too expensive. The license allows you to license what you need and leave out what you don't need."
"The solution's most valuable features include application DDoS protection, bot blocking, and HTTP header verifications."
"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."
"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."
"Rather than locate some things manually, the Sucuri plugin scans and allows us to pinpoint whether there is malware or some problem in the site."
"The most valuable part is the analytics and visualization."
"It significantly eases the workload and streamlines the initial setup required to protect a website."
"For people who own a personal website, this solution is worth trying out since their security solution is somewhat full-fledged."
 

Cons

"They need to improve their support because getting a response for basic requests took around 48 hours, which is too long."
"The platform's control features related to real-time authentication and response time need improvement."
"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"Cloudflare Web Application Firewall should improve visibility for a customer."
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"The ModSecurity core rules need to be updated."
"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."
"What needs to be improved in this solution is the accuracy of its automatic learning feature, because we frequently have to help it manually, particularly to stop blocking things it isn't supposed to block."
"I think the solution is already being phased out."
"For me, an area for improvement in F5 Advanced WAF is the reporting as it isn't so clear."
"The solution is tedious. It takes a lot of discrete settings so one needs to get detailed and granular when they use the solution. It takes you a whole lot of energy and concentration to configure. It needs to be much more straight-forward, like other web solutions."
"The pricing could be more flexible."
"I think the contextual-based component needs a lot of help; it is all based on regular expressions, and we are transitioning off to Signal Sciences on some of our WAF components because of the capabilities Signal Sciences has."
"We get false positives sometimes."
"The administrator's user interface and some of the settings can sometimes be very complicated to understand."
"Confident score: Currently it does not have one and there are cases that most websites flagged are false-positives."
"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."
"In terms of improvement, the cost factor is always there."
"Sucuri could provide help for specific security alerts in-line instead of requiring users to search for it in the help section."
"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."
 

Pricing and Cost Advice

"The annual licensing fee is $10,000 USD."
"It is not too pricey."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"We pay $210 per month for CloudFlare WAF."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"What's my experience with pricing, setup cost, and licensing? I believe the pricing is not the best, but it's reasonable and acceptable. We also use the McAfee system in parallel. In terms of pricing, its okay - not great, but not bad either. It falls in the middle, which is acceptable. In terms of support licensing, last time, we were searching for a solution, and we considered products from resellers rather than directly from the cloud provider. However, the pricing we encountered was exceptionally high. As a result, we are inclined to select support from the reseller."
"The solution's pricing option needs to be more transparent for enterprise clients."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"F5 bundles up services and the bundle is what you pay for rather than individual components."
"I am not sure about pricing but licenses are available on Google."
"The pricing of F5 Advanced WAF is more expensive than other solutions like Radware and CD18, it is quite high."
"After buying the program, you just pay for the support every year."
"The cost is slightly above average."
"Its price is fair. We have done a couple of deals where they were able to give some kind of discount to the customers. The price was initially high for the customers, but after a couple of negotiations, it came within their budget. They were happy with that."
"A yearly license for F5 Advanced WAF is expensive."
"There are various plans available for Fortinet FortiWeb Cloud WAF as a Service, including a trial version."
"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."
"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."
