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 has shifted left and now catches vulnerabilities early in our development workflow
There are a few areas for improvement. The first is scan speed. For large repositories, initial scans can be slow. Incremental scanning helps, but full scans still take considerable time. The second thing is the false positive rate. While Auto-Triage is good, it is not perfect. Occasionally, genuine issues get filtered out and real false positives slip through. The third one is remediation guidance. Aikido Security tells you what is vulnerable, but sometimes the fix suggestions are generic. More specific, actionable remediation steps would save developer time. The fourth one is IDE integrations. It currently works best in CI/CD pipelines. A proper VS Code or JetBrains plugin for real-time scanning while coding would be a significant improvement. From a customer point of view, the following things could change. The first thing is documentation for custom rules. Aikido Security allows you to create custom scanning rules, but the documentation for this feature is surprisingly thin. I spent considerable time in community forums and with trial and error just to configure basic custom rules. Step-by-step guides with real-world examples would make this feature much more accessible. The second thing is better Slack and communication integrations. Currently, security alerts come through email and dashboard notifications, but our team lives in Slack. A more configurable Slack integration that sends contextual alerts directly to the relevant developer, not just a generic channel notification, would dramatically improve response time. The third one is historical trend reporting. While Aikido Security shows current vulnerability status well, generating historical reports showing security posture improvement over time is limited. For presenting security progress to management or stakeholders, better exportable trend reports would be very valuable.

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.

Quotes from Members

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

Pros

"This is a good product; it's reliable and scales well."
"The product has a valuable security control functionality."
"The setup process is very simple for me."
"It is a SaaS solution unlike much of the competition."
"For us, the key feature of Cloudflare is DDoS protection and IP hiding, especially since we are a crypto company."
"We like that there's load balancing, firewall capabilities, DDoS protection, et cetera, all covered by Cloudflare."
"The solution protects our application, which runs on the HTTP protocol, from DDoS attacks."
"The most valuable part of the solution for us overall is exactly that it is a Software-as-a-Service product."
"Aikido Security nests directly in our development workflow and it catches security issues before they reach production."
"Aikido Security has positively impacted my organization significantly because initially we were thinking it would take a month for us to achieve SOC 2 compliance again, and with Aikido Security, we were able to get all codebase vulnerability fixes within a week for all our 13 or 14 repositories that we had."
"Aikido Security offers the best features including being very easy to use, allowing even a normal tech person with some hands-on experience to use this tool and clearly get the results they want."
"Since switching to Aikido Security, I have noticed a positive impact on my team's productivity with measurable results, as we now have measurements."
"Aikido Security saved me several hours each week by automating vulnerability scanning and security checks, reducing the need for manual review and helping me focus on more development."
"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."
"The product's most valuable feature is its ability to set up the rules easily."
"Fastly (Signal Sciences) integrates and tags the intermittent traffic based on patterns. It generates signals and provides them in a dashboard where we can view them and decide whether to allow or deny traffic. It's a more advanced and easy-to-navigate dashboard."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
 

Cons

"A key challenge arises when dealing with numerous integrations with HVAC systems. Depending on the specifics, there might be some configuration mismatches, which necessitate specific support."
"If they add logs history within the Cloudflare offering, that would be a great benefit."
"Support can be challenging at times."
"We don't even use Cloudflare Bot Management because it's too expensive; you need to pay per request, and it's much cheaper to get one or two additional machines."
"There could be an option to duplicate the cluster to maintain the consistency of rules."
"The platform's control features related to real-time authentication and response time need improvement."
"The notification part could be improved. It's very much connected to Web Application Firewall, rate-limiting, and DDoS protection."
"Its stability could be better."
"There are a few areas for improvement. The first is scan speed; for large repositories, initial scans can be slow, and while incremental scanning helps, full scans still take considerable time."
"However, there was one minor issue that I faced. When I had a UUID for an object in the code, Aikido Security was considering it as a secret key, which it was not."
"I think Aikido Security could be improved by addressing its Jira integration, which I feel needs a bit of work."
"I think Aikido Security could improve by reducing some pricing model. Pricing is quite high for a normal user, and if they can make it a little less, it will be much better."
"I think Aikido Security could be improved with more detailed remediation guidance, such as additional beginner-friendly tutorials and enhanced customization for alerts and reporting."
"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."
"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."
"The UI is not very intuitive and could be better."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
 

Pricing and Cost Advice

"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 is expensive."
"The solution's pricing option needs to be more transparent for enterprise clients."
"The pricing model is very straightforward compared to the competition. You just pay per month for the product and usage."
"It starts at $20 and can easily go up to $200 monthly"
"We pay $210 per month for CloudFlare WAF."
"Cloudflare Web Application Firewall is more affordable than other solutions."
"It is not too pricey."
