Executive SummaryUpdated on Jan 11, 2026

Prisma Cloud by Palo Alto Networks and Check Point Harmony Email & Collaboration compete in the cloud security domain. Prisma Cloud appears to have the upper hand with its comprehensive security solutions for multi-cloud environments, while Check Point is noted for its exceptional email security capabilities.

Features: Prisma Cloud offers workload protection, compliance management, and visibility across distributed systems, highly valued for its integration abilities and regular updates. Check Point Harmony Email & Collaboration provides advanced threat detection, effective anti-phishing mechanisms, and seamless integration with collaboration tools, offering sophisticated filtering and attachment sandboxing.

Room for Improvement: Prisma Cloud users suggest enhancing documentation with real-world examples and better integration of certain features, as well as addressing cost and licensing complexities.

Cloud security has improved remote access and has reduced costs for smaller client sites

I have used Cloudflare One's Identity-Aware Proxy, and it is quite straightforward from what I have seen so far. The app registration on the Azure side integrates fully into Cloudflare, and I am very satisfied with that part because it is easy to set up. The integration of Cloudflare One's Secure Web Gateway and Zero Trust Network Access works without any issues. That part is pretty automatic, and if you complete the rest of the setup, it comes together by itself with no issues from my side. What makes it nice is that we can actually start replacing on-site firewalls at this stage for the smaller clients because it does not matter if they go to a coffee shop or work from home; they are still secured by the same connection. The hops get shorter and you get better latency. We have done testing to see if it is better. One thing that we did notice with our proof of concept with our current client is that they have people connecting from the UK. When they used their previous VPN solution, uploading CAD drawings and other files to the server took a long time. They mentioned that it is much quicker on Cloudflare One's solution. I definitely believe that is part of the improved performance, and I am satisfied with that as well. What is nice about Cloudflare One is that it makes the setup easier and also easier to train technicians to maintain it. Compared to legacy systems, we do not need to get fancy firewalls in place that are costly. That is definitely also a cost-saver with Cloudflare One.

Email security has blocked sophisticated phishing and now protects inboxes with AI detection

The only challenge with Check Point Email Security (formerly Harmony Email & Collaboration) is that it is an API-based solution. In an API-based solution, the major challenge is that it can read email content and Google Drive content. This presents a data privacy challenge, and we had to mitigate it by signing a Data Processing Agreement and other agreements. Because it is not a traditional in-line solution, Check Point Email Security (formerly Harmony Email & Collaboration) connects with Google Workspace using API permission and can access email, attachments, sender, recipient information, links, and all metadata is with Check Point. Data storage and everything else is with Check Point, which is the challenge. This solution has a drawback because of API deployment, while other solutions are traditional secure email gateways that are in-line solutions. In those solutions, we need to change the MX record, but with this solution we do not need to change the MX record, which is a pro of API-based deployment. However, there is also a con in that with API solutions, the email is scanned but after delivery in the mailbox.

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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Cloudflare Access is a stable solution."

"It will take the blow rather than our applications should an attack occur."

"I'm very satisfied with the environment and the dashboard."

"Cloudflare One has assisted in securing my remote workforce through a SASE solution with Cloudflare One and the Workers part, although I am not currently using the Workers component."

"The simplicity of the solution is its valuable features as almost no effort was needed to learn the configurations. It is also one of the cheapest firewalls available in this category."

"The best feature is rate limiting. If I'm expecting 500 visits per hour, Cloudflare will limit the requests if I suddenly get 50,000."

"What makes it nice is that we can actually start replacing on-site firewalls at this stage for the smaller clients because it does not matter if they go to a coffee shop or work from home; they are still secured by the same connection."

"Cloudflare DDoS is better than its competitors for its security, deployment, and scalability."

More Cloudflare One pros

"The most valuable features would be its ability to intercept phishing emails and emails laden with malware, viruses, false links, etc."

"Overall, I would rate it ten out of ten."

"The fact that we can share documents without emailing them and still be confident they will go through the corresponding scrutiny is great."

"Being able to mass quarantine and remove emails from end users' mailboxes has become extremely important to us as we have grown in size."

"I appreciate the ease of deployment and the intuitive dashboard. Even someone with basic IT knowledge can easily understand the dashboard and identify potential threats."

"Check Point Harmony Email and Collaboration is the best security software that protects email and collaboration suites in one of the best possible way."

"The product is reliable and sturdy."

"Getting reports and finding threats in the console is easy."

More Check Point Email Security (formerly Harmony Email & Collaboration) pros

"Due to the maturity of most companies, security posture management is the most valuable 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."

"Engineering is thinking it's easy to integrate because we use many Red Hat products."

"It is user-friendly. It has a good look and feel and reporting structure. It provides a single pane of glass. These are the things that I like."

"This solution will ensure that we've got a more secure environment, mitigating any sort of bad actors coming in and either destroying or disrupting the environment."

"CSPM is the most valuable feature."

"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."

"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."

More Prisma Cloud by Palo Alto Networks pros

Cons

"Our customers no longer use Cloudflare because its service is subpar."

"I would like them to include a VPN feature to provide a secure connection to the data center."

"For the topic of improvement, providing some training material is one of my suggestions."

"From a logging perspective, it is still a bit difficult to see exactly what users are being blocked with the current views."

"The software has automated alerts, but the automated alerts are not available in the mobile app."

"Operating and tuning the product is difficult."

"The tool should provide on-premise versions. Currently, all versions are cloud-based."

"Automation could be improved where you can easily add a TLS and SSL certificate to an application or web app if the developer did not include it."

More Cloudflare One cons

"Some files are not scanned thoroughly due to occasional network failures."

"The integration with Gsuite could be improved, especially when reporting the amount of emails it manages to filter."

"There are sometimes leakages of viruses when the system is experiencing network failures."

"The worst thing that I have faced with Check Point has been their support."

"Check Point's technical support is very much of a low level, especially with respect to other vendors and OEMs."

"From time to time, the system's administrators notice the increase in the false-positive alerts being reported by CloudGuard SaaS."

"Check Point Infinity Portal sometimes feels a bit slow, and there are performance issues that should be easy to fix."

"I would love to have their ticket resolution process as fast as possible."

More Check Point Email Security (formerly Harmony Email & Collaboration) cons

"The Palo Alto support needs to improve."

"Currently, custom reports are available, but I feel that those reports are targeting just the L1 or L2 engineers because they are very verbose. So, for every alert, there is a proper description, but as a security posture management portal, Prisma Cloud should give me a dashboard that I can present to my stakeholders, such as CSO, CRO, or CTO. It should be at a little bit higher level. They should definitely put effort into reporting because the reporting does not reflect the requirements of a dashboard for your stakeholders. There are a couple of things that are present on the portal, but we don't have the option to customize dashboards or widgets. There are a limited set of widgets, and those widgets don't add value from the perspective of a security team or any professional who is above L1 or L2 level. Because of this, the reach of Prisma Cloud in an organization or the access to Prisma Cloud will be limited only to L1 and L2 engineers. This is something that their development team should look into."

"Runecast gave us more visibility into VMware's private cloud. We have more environments there, but Prisma's lack of visibility into the private cloud was a downside—there weren't many."

"The licensing is a bit confusing."

"This could be one input that its pricing could be adjusted with respect to other competitors regarding any new features that could be added or improvements to be made in Prisma Cloud (Annual Contract)."

"I don't have any specific notes for improvement; however, if they could continue to focus more on giving users the ability to create custom policies and configurations, that would be ideal."

"Palo Alto needs to add more support staff to improve their response time."

"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."

Pricing and Cost Advice

"My company has to make yearly payments towards the licensing costs attached to the solution. There are no hidden charges apart from the licensing costs of the solution."

"Cloudflare Zero Trust Platform's pricing is good."

"The prices are slightly expensive."

"The price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."

"The pricing of the solution is cheap. The licensing cost is also very low. I rate the cost and pricing a three out of ten."

"The solution is not that expensive."

"The solution's pricing lacks transparency."

"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."

"The cost is similar to other competitors. It's not much higher."

"Due to its pricing, I would say that Check Point Harmony Email & Collaboration is more suitable for medium to enterprise organizations."

"The product is expensive."

"As we are a non-profit organization, we got the tool with a good offer. On a yearly basis, we pay 10,000 Euro for 500 users, which also includes the technical support part."

"The product’s price is very high."

"The pricing is competitive."

"One of the nice features is that the licensing model is elastic, so if you go over your license count, you can add users during your billing cycle and true-up later."

"I rate the platform’s pricing a seven and a half."

More Check Point Email Security (formerly Harmony Email & Collaboration) pricing and cost advice

"Prisma Cloud's licensing system functions as expected with a solid licensing infrastructure."

"The purchasing process was easy and quick. It is a very economical solution."

"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."

"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."

"The pricing is competitive. From what I have seen in the past, it is on par with the others."

"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."

"The Prisma Cloud pricing is good."

"Its licensing cost depends on the type of license such as the business license or the enterprise license. The enterprise license is costlier than the business license, but we get more visibility and more modules. If you have a multi-cloud environment and subscribe to each cloud's native CSPM tool, it is costly. If you are using a single tool like Prisma Cloud, with a single license, you can monitor all environments, such as Google Cloud, Azure, AWS, and Oracle Cloud. The cost of Prisma Cloud is less than the cost of subscribing to the CSPM tool of each cloud provider. This is where Prisma Cloud can save costs."
