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.

Cloud applications have gained stronger protection and real-time defense against web attacks
What really stands out for me in terms of advantages of F5 Silverline Managed Services is that in a single cloud platform, I can protect my web applications against attacks. I can also use my load balancer in F5 because they are providing and acting as a load balancer too, and they will support the volumetric and DDoS attacks and malicious attacks. Regarding the real-time threat intelligence feature, I do use this aspect in F5 Silverline Managed Services. It blocks malicious IPs or bad IPs for my server, protecting against my applications. For example, if someone is a bad actor trying to access via a malicious IP, I can block it because the threat intelligence has the capability to block the malicious IP. The adaptable and flexible security impacts threat response time positively. It is effective because it blocks my malicious traffic. Whenever I face issues related to that application, it automatically routes my traffic to act as a proxy and routes my traffic to their scrubbing center, especially in case of any volumetric attack.

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

"I have not had any issues with this solution, and I would recommend it to others who are interested in using it."
"Very glad the WAF rulesets works out of box, and requires very little tuning or maintenance."
"The stability of Cloudflare Web Application Firewall deserves a perfect 10 out of 10."
"Someone with a basic understanding of networking and security will be able to implement the firewall's basic features within 15 minutes."
"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."
"Caching is the most valuable feature of Cloudflare Web Application Firewall."
"It's pretty convenient and pretty easy to set up and run. And then kind of for static content, it also offers caching."
"We extensively use the solution every day. The solution is very stable; we haven’t seen any glitches."
"This is a good product that you can rely on."
"The most valuable feature of F5 Silverline Managed Services is the benchmark performance."
"The initial setup is very straightforward."
"I think F5 is one of the best web application firewalls in the world."
"The stability of the solution is very good."
"F5 Silverline Web Application Firewall works perfectly fine; it pretty much does everything that an Advanced WAF on-premises should do."
"The 30% efficiency improvement has definitely resulted in increased revenue for us, and with our website performing much better, I am able to achieve faster cycle times in terms of lead to conversion."
"The most valuable features are the configuration and configuring the process."
"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."
"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."
"It significantly eases the workload and streamlines the initial setup required to protect a website."
"The most valuable part is the analytics and visualization."
"For people who own a personal website, this solution is worth trying out since their security solution is somewhat full-fledged."
"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."
 

Cons

"Cloudflare Web Application Firewall should improve visibility for a customer."
"I have experienced some difficulties with Cloudflare's support as a customer based in India."
"The reporting could be improved if it were more granular."
"Their documentation could be better. They don't have documentation that explains everything well. They have documentation for everything you're looking for, but they lack a single piece of documentation to tie everything together. As a new user or beginner, it took us a little bit of time to figure out how to put all these things in place."
"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."
"We have noticed some latency when the call goes through the firewall. That could be improved."
"The user interface is very simple and straightforward, but users need knowledge about DNS to accomplish tasks."
"The ModSecurity core rules need to be updated."
"One thing that was a hassle for us regarding F5 Silverline Managed Services was the deployment of this particular software."
"The navigation is difficult to use."
"F5 Silverline Managed Services could be improved with more intuitive dashboards, a self-service option for respondents, localized support, and better pricing since I think it is high."
"F5 Silverline Web Application Firewall, being a new product in the market or comparatively related to a new product, currently supports less number of PoPs. They should introduce more PoPs. The current number of PoPs that they have is around 10 or 12, which is still relatively less as compared to 2,400 plus PoPs that Akamai offers. The user latency or the number of hops a user needs before reaching the actual web application is less in Akamai because it has its internal fabric to route the traffic. They need to spin up more data to increase its traffic handling capability. They can also include the bot detection capability, though it is a pretty advanced functionality. If they could include DataDome like functionality, that is, bot prediction, then F5 Silverline Web Application Firewall will be top-notch in the market."
"We have complaints about the reliability of this solution."
"The price of F5 Silverline Managed Services could be better, they are not very flexible."
"There is room for improvement in the stability of the solution."
"One negative aspect is that the product is expensive."
"It would greatly benefit customers if they implemented an online chat or messaging system for quicker assistance."
"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."
"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."
"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

"We pay $210 per month for CloudFlare WAF."
"Cloudflare offers different types of subscriptions for businesses, enterprises, and personal users, and the pricing is negotiable."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"The annual licensing fee is $10,000 USD."
"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."
"It starts at $20 and can easily go up to $200 monthly"
"Cloudflare Web Application Firewall is more affordable than other solutions."
"The solution is expensive."
"F5 Silverline Web Application Firewall works based on your bandwidth. They look at the clean bandwidth and do the pricing. 20% of a total pipe would be a clean bandwidth. The list price or a non-negotiated price for F5 Silverline Web Application Firewall would be around $2,200 per application per year for everything that you need. When you get into an enterprise kind of a setup, they negotiate this to the last bit. I would easily take 20% on that, which would be the cost, but it should cover all your Advance WAF features, bot protection, tech campaign, etc. It is built as a package and gives you most of the capability. You don't get the mobile SDK, which is an additional license. Mobile SDK is required only if you're buying or if you have a mobile application, and you are going to instrument F5 or Imperva into your mobile appliance. This anyways would be an additional module. It doesn't come within the WAF, but it is a WAF feature."
"The product’s pricing is reasonable."
"The price of F5 Silverline Managed Services could be reduced."
"The price of F5 Silverline Managed Services could be better, they are not very flexible. The price of the solution is based on the requirements of the enterprise."
"Sucuri offers different plans, both the standard plan and an advanced plan. So there are different plans to choose from."
"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."
"It stands out as a more cost-effective option compared to other cloud-based security services like Cloudflare or JetPass."
"I’d simply say it’s really worth it."
