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

"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."
"The UI is very good. We get all the things within a single UI."
"Integrating with a CI/CD pipeline and incorporating a vulnerability assessment process are highly effective features, especially when combined with runtime protection."
"With the query language, we can analyze logs and find out which IPs are malicious. It also provides a graphical representation. It provides the overall visibility and how the traffic is flowing. We can see where the malicious IP is and whether it is an insider threat or an outsider threat."
"This solution helped us by allowing us to schedule and fix things. This is not an easy thing if you're managing 1,000 plus resources."
"Through Prisma Cloud, we can write Lambda functions, configure policies to check the security posture, and get reports. We can do a lot more."
"It provides good visibility and control regardless of the complexity."
"The most valuable feature is the option to add custom queries using the RQL language that they supply so that we can customize the compliance frameworks to what we need to look for."
"When configuring a web application firewall using Signal Sciences, we configure a rule whereby no one except a few people can access the application."
"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."
 

Cons

"The cost of Prisma Cloud by Palo Alto Networks is too high. I would also appreciate the addition of NLP to reduce the learning curve and make configuring queries more user-friendly."
"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."
"While the code security feature has undergone recent enhancements, there is room for improvement in terms of its cost module."
"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."
"The security automation capabilities are average."
"The regional cost of Prisma Cloud in South Africa is high and could be improved."
"Prisma is good about compliance, and their support is excellent, but they struggle with automation and integration. They need to stay on top of the newest types of connectors. How can you connect other applications and other tools in order for this to work cohesively? That's a challenge."
"The UI is good, however, they could improve the experience."
"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."
"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."
"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."
 

Pricing and Cost Advice

"I wouldn't mind if it were cheaper. We are spending a fair amount of money on Prisma Cloud."
"Prisma Cloud is remarkably expensive."
"The pricing structure is easy to understand. Depending on the use case the pricing of the solution can be different. There are not any additional costs to the standard living fees."
"The pricing is good. They gave us some good discounts right at the end of the year based on the value that it brings, visibility, and the ability to build in cloud, compliance, and security within one dashboard."
"The pricing and licensing are expensive compared to the other offerings that we considered."
"The cost was not on the higher side. Overall, the cost gets recovered with its implementation."
"The Prisma Cloud pricing is good."
"If a competitor came along and said, "We'll give you half the price," that doesn't necessarily mean that's the right answer, at all. We wouldn't necessarily entertain it that way. Does it do what we need it to do? Does it work with the things that we want it to work with? That is the important part for us. Pricing wasn't the big consideration it might be in some organizations. We spend millions on public cloud. In that context, it would not make sense to worry about the small price differences that you get between the products."
"Signal Sciences is pretty cheap compared to other solutions."
"The product has an affordable cost."
"The pricing is 50% less than Akamai."
