Image scanning has supported consistent security practices during cloud deployment
On a scale of ten, we would say people are happy with Prisma Cloud by Palo Alto Networks for the part we use. People are okay with it. We probably would give an eight. We don't give ten because if we don't use the other parts of Prisma Cloud by Palo Alto Networks, it's because it was difficult to implement from an operational point of view. We could have deployed the runtime monitoring with Prisma Cloud by Palo Alto Networks, but within our organization at our company, it was very difficult to find who would be the owner for the alerts. People have other tools and in the end, we don't use the full capabilities of a product that we pay for. It's partially related to the difficulty to integrate Prisma Cloud by Palo Alto Networks runtime in our company's support process. We don't use the real-time monitoring part of Prisma Cloud by Palo Alto Networks. We don't know about the automated remediation feature of Prisma Cloud by Palo Alto Networks.

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

"From the CSPM perspective, RQL in Prisma Cloud by Palo Alto Networks is a feature where we can conduct any kind of investigation and create our own custom policies, which is really helpful because in the cloud, there are millions of assets and with RQL, we can drill down to as fine a level as per our requirement."
"Prisma Cloud has good integrations, provides the visibility and control we need, is far more reasonable for the customers cost-wise, and is a very good preventative tool for helping us identify misconfigurations, reduce false positives, and focus on the real risks in our cloud environment."
"Prisma has massively reduced our alert investigation times; it is 50 times quicker, turning an issue investigation from two hours into two minutes compared to a cloud-native solution."
"Prisma Cloud provides the needed visibility and control regardless of how complex and distributed the cloud environments become."
"The most valuable features of the solution are areas like compliance and asset inventories, along with runtime protection."
"It also provides us with a single tool to manage our entire cloud architecture. In fact, we are using a multi-account strategy with our AWS organization. We use Prisma as a single source of truth to identify high- or medium-severity threats inside our organization."
"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."
"Through Prisma Cloud, we can write Lambda functions, configure policies to check the security posture, and get reports. We can do a lot more."
"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."
"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."
"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

"I believe there are some issues with the product's maturity. In some cases, it could malfunction concerning Cloud Native."
"Palo Alto needs to add more support staff to improve their response time."
"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."
"It's not really on par with, or catering to, what other products are looking at in terms of SAST and DAST capabilities. For those, you'd probably go to the market and look at something like Veracode or WhiteHat."
"Support is an area that needs improvement."
"The IM security has room for improvement."
"The user interface should be improved and made easier."
"Based on my experience, the customization—especially the interface and some of the product identification components—is not as customizable as it could be. But it makes up for that with the fact that we can access the API and then build our own systems to read the data and then process and parse it and hand it to our teams."
"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."
"The UI is not very intuitive and could be better."
"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

"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."
"The pricing and the licensing are both very fair... The biggest advice I would give in terms of costs would be to try to understand what the growth is going to look like. That's really been our biggest struggle, that we don't have an idea of what our future growth is going to be on the platform. We go from X number of licenses to Y number of licenses without a plan on how we're going to get from A to B, and a lot of that comes as a bit of a surprise. It can make budgeting a real challenge for it."
"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."
"Prisma Cloud by Palo Alto Networks is a highly expensive solution."
"The licensing cost is a bit high on the compute side."
"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."
"You can expect a premium price because it is a premium quality product by a leading supplier."
"Almost all the CSPM tools are pretty expensive."
"Signal Sciences is pretty cheap compared to other solutions."
"The product has an affordable cost."
"The pricing is 50% less than Akamai."
