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.
Harsh_Vardhan - PeerSpot reviewer
Provides visibility and control that our customers need
Different modules are valuable for different customers. We are leveraging CSPM. It is one of the best solutions for comprehensive visibility into cloud resource configurations and compliance. It has a lot of out-of-the-box policies, and the visibility that we are getting is impressive. The DSPM module is valuable. This is the latest one that Palo Alto procured from Dig Security. No competitor provides this functionality in a single pane of glass. The support for Linux and container security is also very good. That is the beauty of Prisma Cloud. However, in terms of Windows security, Prisma Cloud is lacking because currently, there is no runtime protection available. The UI is very good. We get all the things within a single UI. It is easy to use. A new user can easily understand it. It is very user-friendly.
Shashank N - PeerSpot reviewer
Provides good stability, but the agent-based approach could be more convenient
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. Additionally, the agent-based approach presents challenges with managing agents across versions and dependencies on specific application platforms like Apache or NGINX, leading to compatibility issues and complexity in integration. This agent-based system proved particularly difficult to manage.

Quotes from Members

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

Pros

"It's very user-friendly."
"The solution is very good at mitigating threats."
"Cloudflare has many features."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"Its most significant benefit to date is the speed with which it refreshes DNS records on the internet once you change it. If you are changing a website or registering a new record, it is very quick."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"The most valuable feature of Cloudflare is the GUI. You are able to control the solution very well through the interface. There is a lot of functionality that is embedded in the service."
"The two most valuable features are container security and the capability to discover workloads."
"The CWP module, runtime protection, and WAAS API are valuable."
"Prisma Cloud's real-time detection and monitoring of our entire system is the most useful."
"Its ease of integration is valuable because we need to get the solution out of the door quickly, so speed and ease matter."
"Comprehensive and valuable for providing security. It is scalable, its stability is impressive, and setting it up is straightforward."
"The CSPM and CWPP functionalities are pretty good."
"I was looking for a vulnerability scanner and I was looking for one place in which I could find everything. This tool not only does vulnerability scanning, but it also gives me an asset management tool."
"Through Prisma Cloud, we can write Lambda functions, configure policies to check the security posture, and get reports. We can do a lot more."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
"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."
"The product's most valuable feature is its ability to set up the rules easily."
"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."
 

Cons

"It should confirm audit findings of the assigned area with auditees to ensure that the audit conclusions are based on an accurate understanding of the issues."
"The product support needs to be accessible from more places, a wider area of coverage."
"I believe they currently have this feature, but there will most likely be integration with APIs so we can control some features through API."
"Cloudflare should add more documentation and pricing to the cloud version."
"It would be good if Cloudflare could have more servers for better traffic routing or an increase in the traffic routed. This is what I'd like to improve in Cloudflare."
"DNS Management."
"The documentation could improve for Cloudflare DNS."
"We have noticed multiple instances where Cloudflare falsely indicates that our servers are down, even when there is no actual load on them. This makes it challenging for us to identify the exact issue."
"A couple of exporting functionalities should be more user-friendly because if I want to export something, I can get a lot of data visible to that particular CSV."
"One of the main backlogs in their development is in the area of integration. For example, we have ServiceNow in place for ticket management and Prisma Cloud is supposed to send closure emails for incidents. But from time to time, it fails to do so. We have several other mismatches between Prisma Cloud and ServiceNow."
"A better correlation between the multiple products Prisma Cloud contains would be crucial. It would reduce the time spent looking at reports and enable you to get all the actionable insights across products. I think that Palo Alto is working on it, but they need to work faster because it doesn't make sense to have all these products in a single pane of glass without any correlation between them."
"The Fargate security microservice that's running doesn't support blocking features, which would be helpful. Another issue is the lifecycle. It isn't easy to upgrade if we have a console in Fargate."
"I believe there are some issues with the product's maturity. In some cases, it could malfunction concerning Cloud Native."
"We'd like to have more native integration with clouds and additional security checks in the future."
"The information presented in the UI sometimes doesn't look intuitive enough."
"The area for improvement is less about the product and more about the upsell. If we've already agreed that we'd like your product x, y, or z, don't try to add fries to my burger. I don't need it."
"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."
"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."
 

Pricing and Cost Advice

"We don't have any issues with the price."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"The tool is a premium product, so it is very expensive."
"The pricing for the service is reasonable, neither excessively cheap nor prohibitively expensive. It aligns well with the value of their solution."
"A free version of the solution is available."
"I think the pricing is competitive. I think as far as licensing is concerned it's pretty straightforward because it's based on domain. It's just that sometimes domains could be tricky with some customers."
"The product's pricing is cheap."
"The price of the solution is expensive."
"If you pay for three years of Palo Alto, it's better. If you're planning on doing this, it's obviously not going to be for one year, so it's better if you go with a three-year license... The only challenge we have is with the public cloud vendor pricing. The biggest lesson I have learned is around the issues related to pricing for public cloud. So when you are doing your segmentation and design, it is extremely important that you work with someone who knows and understands what kinds of needs you will have in the future and how what you are doing will affect you in terms of costs."
"From my exposure so far, they have been really flexible on whatever your current state is, with a view to what the future state might be. There's no hard sell. They "get" the journey that you're on, and they're trying to help you embrace cloud security, governance, and compliance as you go."
"The price is high. In the future, when there are more competitors at the same level with different clouds, maybe the position will be different."
"Prisma Cloud is more expensive than Check Point CloudGuard."
"The pricing for Prisma Cloud is high. Providing a pay-as-you-go model or pricing options tailored for medium and small enterprises could help attract more clients."
"The cost was not on the higher side. Overall, the cost gets recovered with its implementation."
"Regarding Prisma Cloud's pricing, we started small, and then we just kept on growing."
"Prisma Cloud's licensing system functions as expected with a solid licensing infrastructure."
"The pricing is 50% less than Akamai."
"The product has an affordable cost."
"Signal Sciences is pretty cheap compared to other solutions."
