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 most valuable features of the solution are performance and security."
"The attacker won't have details since my public IP is anonymous. It offers us good privacy."
"It is a stable solution. I rate the stability a ten out of ten...I rate the scalability a ten out of ten."
"The most valuable feature is its usability."
"The UI is good."
"Its ease of integration with Office 365 and the fact that it's a good product compared to what I had before"
"The most valuable feature of the solution is external DNS. It is also very secure. They have their own main server and once you configure it, the product takes care of everything. There are no issues in resolving IPs and low latency is also present."
"The most valuable feature of Cloudflare DNS is security."
"The CWP module, runtime protection, and WAAS API are valuable."
"My favorite feature is the CWPP module. We can define various kinds of rules for vulnerabilities, incidents, or suspicious activities."
"The dynamic workload identity creation, attestation, and assignment is the best feature. In addition, the application dependency map across heterogeneous environments for compliance is a striking feature."
"We were pleased with Prisma's custom and built-in reports. We could go into the dashboard and see all these notifications telling us which subscriptions didn't have TLS 1.2 enabled. The security controls were the most valuable features."
"Most of the customers we are tackling have different tools and solutions, like Qualys, Nessus, and vulnerability management assessment solutions. There are plugins for them, and we can integrate Prisma Cloud with them. We can enrich our telemetry with their data and use the predefined correlation rules in Prisma Cloud. That means we have that work done in seconds."
"The product is quite good for providing multi-clouds or cross-cloud security from a single-pane -of-glass."
"The thing that I like the most is that when it comes to runtime events, whenever we see an event, we are able to look through the logs. It is pretty easy to look back through everything that took place."
"Comprehensive and valuable for providing security. It is scalable, its stability is impressive, and setting it up is straightforward."
"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."
"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

"Latencies are always a problem."
"In the last two years, there has been a certain amount of downtime when using the VDM."
"The solution could use more analytics on the backend to give us more insights into everything. More reports would be helpful."
"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."
"The integration of LLMs on the dashboard is something that is needed in the tool."
"Support response time could be improved."
"Integration involving API with other products could be more user-friendly."
"The pricing could be improved."
"Prisma Cloud's dashboards should be customizable. That's very important. Other similar solutions are more elastic so you have the power to create customized dashboards. In Prisma Cloud, you cannot do that."
"It does not provide runtime security or protection for Windows Server. It is currently lacking in terms of Windows environment."
"We'd like to have more native integration with clouds and additional security checks in the future."
"More documentation with real-world use cases would be helpful."
"The UX part of Prisma's user interface could be simplified and the metrics tool should be highlighted more."
"Sometimes we do get false alerts. That should be improved."
"The alignment of Twistlock Defender agents with image repositories needs improvement. These deployed agents have no way of differentiating between on-premise and cloud-based image repositories. If I deploy a Defender agent to secure an on-premise Kubernetes cluster, that agent also tries to scan my ECR image repositories on AWS. So, we have limited options for aligning those Defenders with the repositories that we want them to scan. It is scanning everything rather than giving us the ability to be real granular in choosing which agents can scan which repositories."
"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."
 

Pricing and Cost Advice

"The solution has many features but there are ones that you need to pay for. Sometimes you have to find out which is available for free and which you have to pay for."
"The pricing depends on the usage, but the cheapest would be around 5,000 USD a month."
"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."
"When you compare Cloudflare DNS to other solutions, such as Akamai, the price is reasonable."
"We are using the free version."
"It's a premium model. You can start at zero and work your way up to the enterprise model, which has a very high pricing level."
"The cost primarily depends on the size of the organization."
"The tool is a premium product, so it is very expensive."
"In general, Prisma Cloud is much cheaper than cloud-native services."
"Prisma Cloud by Palo Alto Networks has helped the company save some money. Cost-wise, it's okay."
"I wouldn't mind if it were cheaper. We are spending a fair amount of money on Prisma Cloud."
"We are encountering some resistance in the African market regarding the cost of Prisma Cloud."
"The product is very expensive, but the cost is a necessary evil; I don't know how we could have any kind of cloud presence without this type of monitoring. The pricing is calculated by module and resource usage. Ultimately, it saves us money in the amount of time we would spend uncovering what it uncovers, and we might not make the required discoveries without it anyway. Prisma offers incredible value, though I wish it were cheaper."
"Prisma Cloud is a value-back cloud-managed solution; cloud-native solutions are quite expensive."
"Prisma Cloud's licensing system functions as expected with a solid licensing infrastructure."
"I don't know a better way to do it, but their licensing is a little confusing. That's due to the breadth of different types of technologies they are trying to cover. The way you license depends on where you're securing. When they were Twistlock it was a simple licensing scheme and you could tell what you were doing. Now that they've changed that scheme with Palo Alto, it is quite confusing. It's very difficult to predict what your costs are going to be as you try to expand coverage."
"The pricing is 50% less than Akamai."
"The product has an affordable cost."
"Signal Sciences is pretty cheap compared to other solutions."
