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

"Prisma Cloud's inventory reporting is pretty good."

"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."

"I find the CSPM area to be a more valuable and flexible feature."

"The features of Prisma Cloud by Palo Alto Networks are overall satisfying, although I would like to verify some aspects."

"The most valuable feature is the continuous cloud compliance monitoring and alerting."

"This positively affected our confidence in your security and compliance. No matter how complex the environment is, the the seamless integration from the top layer itself give us the immediate visibility on the number of services."

"CSPM is the most valuable feature."

"Through Prisma Cloud, we can write Lambda functions, configure policies to check the security posture, and get reports. We can do a lot more."

More Prisma Cloud by Palo Alto Networks pros

"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."

"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."

Cons

"Support is an area that needs improvement."

"When it comes to protecting the full cloud-native stack, it has the right breadth. They're covering all the topics I would care about, like container, cloud configuration, and serverless. There's one gap. There could be a better set of features around identity management—native AWS—IAM roles, and service account management. The depth in each of those areas varies a little bit. While they may have the breadth, I think there's still work to do in flushing out each of those feature sets."

"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 solution does not currently support servers for GCP."

"We would like to have the detections be more contemporaneous. For example, we've seen detections of an overprivileged user or whatever it might be in any of the hundreds of Prisma policies, where there are 50 minutes of latency between the event and the alert."

"The challenge that Palo Alto and Prisma have is that, at times, the instructions in an event are a little bit dated and they're not usable. That doesn't apply to all the instructions, but there are times where, for example, the Microsoft or the Amazon side has made some changes and Palo Alto or Prisma was not aware of them. So as we try to remediate an alert in such a case, the instructions absolutely do not work. Then we open up a ticket and they'll reply, "Oh yeah, the API for so-and-so vendor changed and we'll have to work with them on that." That area could be done a little better."

"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."

"Prisma Cloud is very comprehensive, but there should be better support for the customization of the reports. If Palo Alto can have more customized reports available or give an option to the users to customize the reports, that would be great."

More Prisma Cloud by Palo Alto Networks cons

"Fastly don't support caching for China users. That's the only feature lacking compared to Akamai."

"Even if we create some custom rules, Signal Sciences cannot capture some of the malicious traffic."

"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."

Pricing and Cost Advice

"The licensing cost is a bit high on the compute side."

"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."

"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."

"One thing we're very pleased about is how the licensing model for Prisma is based on work resources. You buy a certain amount of work resources and then, as they enable new capabilities within Prisma, it just takes those work resource units and applies them to new features. This enables us to test and use the new features without having to go back and ask for and procure a whole new product, which could require going through weeks, and maybe months, of a procurement process."

"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."

"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 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."

"We are encountering some resistance in the African market regarding the cost of Prisma Cloud."

"The pricing is 50% less than Akamai."

"The product has an affordable cost."
