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.
Mohammad Qaw - PeerSpot reviewer
It gives you one console to see all of your assets, review their configurations, and build your processes
Most customers use Prisma Cloud for visibility and compliance. Prisma has so many features, but many organizations do not use them. They primarily use the visibility part to connect all their cloud accounts and hosts for visibility to see if they are missing any security controls or if they have any misconfigurations. You can connect it to cloud environments such as Azure, AWS, Oracle Cloud, Alibaba, etc., or to an on-prem data center. Prisma Cloud gives you so many options to automate processes related to your daily operations. When it comes to cybersecurity, you can automate things with their existing APIs. They also have out-of-the-box integrations with many solutions. I have not seen any limitations. Everything is customizable. You can do whatever you want, defining the reporting and custom use cases. They recently updated the UI, so it's much better than before.
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

"The simplicity of the overall dashboard makes it a great product for a user like me who has less understanding of the internet than a developer or other more technical people. It gives me peace of mind. I also love the easy customization of the Page Rules."
"The most valuable feature of Cloudflare DNS is its global reach and it is always evolving."
"When using services like Heroku, Cloudflare is very useful for CNAME flattening. I also use it for their end-to-end SSL with TLS authentication on nginx for securing servers."
"The most valuable feature is the web application firewall."
"It is a fast and secure DNS."
"Cloudflare consolidates various capabilities into one product, streamlining processes."
"The solution automatically detects and responds to certain types of traffic based on geolocation."
"There are key things that are used for our enterprise customers, such as Lambda and DNS."
"Prisma Cloud has enabled us to take a very strong preventive approach to cloud security. One of the hardest things with cloud is getting visibility into workloads. With Prisma Cloud, you can go in and get that visibility, then set up policies to alert on risky behavior, e.g., if there are security groups or firewall ports open up. So, it is very helpful in preventing configuration errors in the cloud by having visibility. If there are issues, then you can find them and fix them."
"The CSPM and CWPP functionalities are pretty good."
"The client wasn't using all of the features, but the one that stood out was infrastructure-as-code (IaC). I built IaC use cases and was trying to get them to use it. I also liked cloud workload protection. I worked with the vulnerability management team to develop a process. It's a manual process, so it can be challenging to remediate many image or container issues. It was nice that we could build out a reporting process and download the reports. The reports are solid."
"The first aspect that is important is the fact that Prisma Cloud is cloud-agnostic. It's actually available for the five top cloud providers: AWS, GCP, Azure, Oracle, and Alibaba Cloud. The second aspect is the fact that we can write our own rules to try to detect misconfigurations in those environments."
"In the GlobalProtect module, we can easily guide users experiencing connection issues through the notification column."
"The ability to monitor the artifact repository is one of the most valuable features because we have a disparate set of development processes, but everything tends to land in a common set of artifact repositories. The solution gives us a single point where we can apply security control for monitoring. That's really helpful."
"Its ease of integration is valuable because we need to get the solution out of the door quickly, so speed and ease matter."
"The application visibility is amazing. For example, sometimes we don't know what a particular custom port is for and what is running on it. The visibility enables us to identify applications, what the protocol is, and what service is behind it. Within Azure, it is doing a great job of providing visibility. We know exactly what is passing through our network. If there is an issue of any sort we are able to quickly detect it and fix the problem."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
"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."
"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."
 

Cons

"Areas like how assessment, discovery, and payload are dealt with and how it all comes into your organization can be considered when trying to make suggestions to Cloudflare for improvements."
"For the free and Pro plans, Cloudflare could use a simple bot to provide information to users. This would improve support, especially for less advanced users who utilize the free components."
"Latencies are always a problem."
"DNS Management."
"Cloudflare does not have an on-premise solution. If they had different approaches they could be better suited to accommodate more customers, such as on-premise and hybrid deployments. For example, hybrid deployments would be useful where you could move the traffic from the enterprise to the cloud."
"The product needs to improve its automation."
"We are a product integrator and reseller, and we would like to have a better partner relationship, similar to a channel sales relationship. Sometimes we are on our own or get diverted by Cloudflare because they have direct sales, which competes with us and makes it difficult to build a relationship with this company since we want to be an MSP or a managed service provider for the solution."
"Cloudflare could be improved by introducing a mid-tier pricing option."
"One thing that is missing is Cloud Run runtime security—serverless. That would be great to have in the tool. It's not that easy to have Cloud Run in specific environments."
"The access controls for our bank roles were not granular enough. We needed specific people to do particular actions, and we often had to give some people way too much access for them to be able to do what they needed in Prisma. They couldn't do their jobs if they didn't have that level of access, so other people had to do that part for them. It would help to have more granular role-based access controls."
"Prisma Cloud lags behind in terms of security automation capabilities."
"I think Prisma Cloud could improve its preventive governance policy and CWP run time modules."
"The data security model needs improvement due to integration issues with certain features and cloud providers. With Palo Alto now utilizing a tool from an Israeli startup in Prisma Cloud, the integration is slow, and some features are blocked or not supported."
"When there are updates, whether daily, weekly, or monthly, it needs configuration or permission adjustments. There is no automation for that, which is too bad."
"There needs to be a mechanism that allows me to manually configure compliance more easily."
"Some module customization might be needed and certain features like adding custom labels are currently unavailable unless we have administrator access."
"The UI is not very intuitive and could be better."
"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."
 

Pricing and Cost Advice

"Cloudflare's pricing is not much higher and is good for middle-level organizations."
"The tool is a premium product, so it is very expensive."
"We don't have any issues with the price."
"We are using the free tier of the solution."
"The solution is expensive when compared to other products but offers unlimited bandwidth."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"The price is reasonable."
"So far I use free tier and happy with it. You can subscribe to business package if needed."
"Its price is reasonable as compared to other products. The main challenge is explaining the licensing model to customers. It isn't a problem related to Palo Alto. Commonly, people don't understand cloud licensing or security licensing. When they have fixed virtual machines, they know what they are going to be charged, but when it comes to cloud automation, it is hard for them to get clarity in case of high workloads or when they have enabled auto-scaling, etc. It would be helpful if Palo Alto can educate people on their licensing programs."
"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."
"Prisma Cloud by Palo Alto Networks is a highly expensive solution."
"It is fairly priced. However, its price can be better so that small banks or small organizations can afford it and adopt it to secure their environment and data."
"Prisma Cloud by Palo Alto Networks carries a higher cost, but its enhanced security measures justify the expense."
"Prisma Cloud is more expensive than Check Point CloudGuard."
"Prisma Cloud Enterprise is a costly solution. You need a license for all the components. At the same time, you have everything under one roof, so I think it's still justified."
"The purchasing process was easy and quick. It is a very economical solution."
"Signal Sciences is pretty cheap compared to other solutions."
"The pricing is 50% less than Akamai."
"The product has an affordable cost."
