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.

Security threats have been reduced through seamless deployment and strong integration with other tools

I have used Fortinet FortiWeb's integration features. We have easily integrated all of the applications with the product. Most of the applications we are using are in-house built. My technical team is looking after the best features. I have not used it extensively for maybe two and a half years. I have been involved in the installation, but I am not actually using the product. I work with it from time to time but not extensively. I would assess Fortinet FortiWeb's adaptive machine learning and artificial intelligence as having new patches installed regarding artificial intelligence, but when we bought it, I think the learning feature was there. Now they have installed artificial intelligence features through patches. We have a complete portfolio of Fortinet in our organization, including FortiMail, Fortinet FortiWeb, and FortiGate, along with multi-factor authentication. All of the products are from Fortinet. Fortinet tools integrate with each other and work in conjunction. I think Fortinet FortiWeb has helped us meet regulatory compliance because we are not a regulatory organization, but our sister organization is regulatory. We have regulatory compliance with the International Civil Aviation Authority, whose audit teams have checked our data center and these security products, and they are satisfied with us. The question about leveraging Fortinet FortiWeb's automated policy management does not pertain to my domain because I am not so technical, but I am in a management role now. My engineer is more technical than me. I would rate this product an eight point five out of ten.

Room for improvement with user interface while competitive pricing impresses

It is managed through Infrastructure as Code, so all configurations can be managed in the code itself, which is beneficial. Because it uses rules, it is easy to set up, and we have many different sites where the configurations are straightforward. Though the UI is not very interactive, which is a downside, we can manage many things. The UI is not very intuitive and could be better. However, we manage all the configurations through code, which is easy to maintain. It has extensive anomaly detection capabilities, so the traffic is classified into several categories where thresholds can be defined and customized based on false positives and false negatives. This is advantageous because you do not need to tweak it very often. Once you set it up, an audit once a quarter would suffice. Because The Fastly Next-Gen WAF (powered by Signal Sciences) is API-driven, we have integrations with the CI/CD pipeline through GitHub Actions, making it easy to integrate.

"Security Fabric integration is really a value-added feature as FortiWeb can interact with the rest of the client’s Fortinet pack to provide an intelligent security layer like FortiSIEM for central log management and correlation, FortiGate, and FortiSandbox for malware analysis."

"It offers some feedback and suggestions that guide our system development while helping our vendors to update their applications and fix any issues or bugs."

"The product's most valuable feature is its ability to set up the rules easily."

Cons

"They have some limitations with third-party integrations."

"The reporting could be more granular."

"I have experienced some difficulties with Cloudflare's support as a customer based in India."

"The ModSecurity core rules need to be updated."

"The accuracy of the Cloudflare Web Application Firewall could be improved by reducing the number of false-negative alerts."

"The platform's control features related to real-time authentication and response time need improvement."

"Cloudflare should update the version of the ModSecurity core rule set that they run on."

More Cloudflare Web Application Firewall cons

"It is not entirely user-friendly."

"I would like to see the Application Delivery Control (ADC) and Web Application Firewall (WAF) combined in one device."

"No solution is 100% secure and the security could always be worked on."

"The reporting could be optimized."

"I would like to have an antivirus option."

"New releases and old releases have some bugs, some features do not work as good as we want but every new release the Fortinet team fixes up problems."

"I think Fortinet must make an effort in terms of upgrade procedures."

More Fortinet FortiWeb cons

"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."

"The areas that could be improved in Signal Sciences include the effectiveness of rules, as many didn't function optimally and required custom rule-writing to address bypasses for WAF."

"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."

"The UI is not very intuitive and could be better."

"FortiWeb has a good presence because of its price."

"Its subscription prices are cheaper, and it is not very expensive. From a price perspective, Fortinet is a very well-known security vendor. Subscriptions are very simple. They have a couple of licenses on an appliance, and that's it. The cost is not that big. One license is 40K, which they give with all the products. Another one includes the subscriptions for threat prevention, IPS, sandboxing, etc, which is more than enough."

"I rate the product price a four on a scale of one to ten, where one is a high price, and ten is a low price."

"FortiWeb is more expensive than some competing products."

"It is a cheap solution."
