Executive SummaryUpdated on Apr 24, 2026

Check Point Harmony Email & Collaboration and Microsoft Exchange Online Protection are contenders in the email security category. Check Point Harmony Email & Collaboration seems to have the upper hand with its AI-driven phishing protection and intuitive dashboards, which users find easy to deploy and manage, particularly when integrated with Microsoft 365.

Features: Check Point Harmony Email & Collaboration offers AI-powered threat intelligence, reducing phishing alerts and incidents significantly. Users value its intuitive dashboards and seamless integration with Microsoft 365. Its AI capabilities provide advanced phishing protection, setting it apart from other solutions. Microsoft Exchange Online Protection features strong integration with Microsoft's infrastructure, providing robust email security measures like anti-phishing and malware protection. Users appreciate its ease of administration and reliable core features.

Room for Improvement: Check Point Harmony Email & Collaboration could improve its dashboard's flexibility and offer better integration with more systems beyond Microsoft 365 and Google Workspace. Users also point out the false-positive rates and the complexity of deployment. Microsoft Exchange Online Protection needs a more intuitive user interface and reduced complexity in its configuration processes. Users suggest enhancing reporting capabilities and lowering overall pricing for broader accessibility.

Ease of Deployment and Customer Service: Check Point Harmony Email & Collaboration is known for swift API-based deployment and seamless integration, especially with Microsoft 365, although its initial phase can be complex. Customer support responsiveness receives mixed reviews. Microsoft Exchange Online Protection offers easy implementation within existing Microsoft environments, benefiting from Office 365 integration. However, areas like real-time user support and post-deployment guidance could improve. Users highlight consistent technical support as a strong aspect of Microsoft's offering.

Pricing and ROI: Check Point Harmony Email & Collaboration is seen as slightly more expensive, suited for medium to enterprise-level organizations with pricing justified by its features. It is praised for ROI, particularly in reducing phishing alerts, saving substantial time and costs. Microsoft Exchange Online Protection is competitively priced but could lower costs further to attract a larger user base. It provides comprehensive features bundled with Microsoft 365, and users are satisfied with its cost-effectiveness compared to standalone solutions, although they mention potential hidden costs associated with necessary add-ons.

CV

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 effectively detects a wide range of threats and improves productivity
Since we have been using Check Point Harmony Email & Collaboration for a year, we haven't encountered significant challenges. However, it would be beneficial if it could support other email security services beyond Microsoft and Google. Integration with other platforms would enhance its appeal since the features are commendable. While the analytics are commendable, they don't provide deep dive insights. They show the overall counts of malware, phishing, and business compromise emails, but there isn't a robust ability to dive deeper into those categories to see specifics. Analytics should allow us to explore which users received malware emails the most or trends among departments. Currently, we have to sift through manually, which is not ideal. A more profound analytical capability would elevate the tool to become the complete email security solution for any user.

Layered email security has protected sensitive research and still flags phishing in real time
The valuable features of Microsoft Exchange Online Protection (EOP) include providing an additional layer of protection, as it builds on the basic Exchange level of security that allows us to get our work done. Another feature I appreciate is the ability to question things, as our Exchange server allows us to identify in real-time if an email is a phishing email or spam email. It really helps us identify risks, especially through our external exchanges via email or through our cloud-based platforms. Our Exchange system blocks any embedded AI from all our applications and products, so we cannot use embedded AI in our daily work from our official laptops because we have secure information. The system is quite locked down.

Quotes from Members

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

Pros

"The blocking feature is very good."
"Cloudflare Zero Trust Platform removes the risk of exposing the applications to the public."
"It is a stable solution."
"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."
"I'm very satisfied with the environment and the dashboard."
"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."
"It's a perfect solution from my perspective; it's easy to understand and easy to configure."
More Cloudflare One pros
"It helped us to bring security compliance and ensure system robustness throughout."

More Microsoft Exchange Online Protection (EOP) pros
 

Cons

"Our customers no longer use Cloudflare because its service is subpar."
"Feedback could be enhanced."
"For the topic of improvement, providing some training material is one of my suggestions."
"Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions."
"Operating and tuning the product is difficult."
"They don't have a person to provide support for customers using the solution under their free plan."
"Lacks a VPN feature to provide a secure connection to the data center."
"The response time for support must be reduced."
More Cloudflare One cons
"The NAVEX metrics that I have been using on the CloudGuard dashboard cannot be exported. If they were to add report exporting capabilities on each of metric objects on the dashboard, that would be awesome."
"They could continue to offer more stringent security policy measures for threat point management."
"The documentation is a little unintuitive, and I make an additional effort for the first deployment."
"I would love to have their ticket resolution process as fast as possible."
"The integration with Gsuite could be improved, especially when reporting the amount of emails it manages to filter."
"We still get some false positives. There are times when legitimate stuff gets flagged and it could be that somebody is expecting a very important email but they don't end up getting it."
"During the East Coast server outage with Amazon service this week, mail was delivered and then pulled back because Harmony wasn't working properly and needed to scan it."
"We are unable to export the reports from the dashboard, and if it is possible to do then it is not intuitive."
More Check Point Email Security (formerly Harmony Email & Collaboration) cons
"It doesn't protect against everything. We do need protection for, for example, endpoints."
"Online Protection has an issue in that it doesn't provide an option to stop impersonation."
"Some of the searchability when looking for specifics in Exchange logs is tedious."
"The management interface of Microsoft Exchange Online Protection (EOP) could be intuitive."
"Not all settings can be configured automatically and most still require manual configuration. However, there is an automation tool available that can be used to input all the configurations either as a script or a tool it would be helpful."
"The solution needs to improve its backup."
"If a company wants to put in line back-to-back anti-spam solutions, they need to work on that part because Microsoft recommends either you use EOP as a front line or you don't use it."
"The price could be lower."
More Microsoft Exchange Online Protection (EOP) cons
 

Pricing and Cost Advice

"The solution's pricing lacks transparency."
"The solution is not that expensive."
"The pricing is somewhere in the middle. I would rate the pricing a seven out of ten."
"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."
"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 price tag is no longer $200,000, but rather $300,000 to $400,000. It's twice."
"The prices are slightly 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."
"There are absolutely no additional costs to the standard licensing fees. One of the wonderful pieces is that CloudGuard SaaS is all-inclusive in its licensing. There's no a-la-carte functionality. You're getting 100 percent of the product for the licensing that you're paying."
"Being able to keep the phishing campaigns out of my company has been ROI for me."
"Cost is the main concern that every customer takes into consideration, and Check Point always negotiates a price that is affordable."
"Usually, we pay for the licensing part on a yearly basis and not on a monthly basis. If Check Point's team is providing a good amount of discount, then it is very easy for us to select it since its competitors are also giving the best prices or best discounts."
"You can get CloudGuard as part of Infinity. When you do the solution through Infinity, it's a per user type of license cost."
"The product is expensive."
"The product’s price is very high."
More Check Point Email Security (formerly Harmony Email & Collaboration) pricing and cost advice
"The solution should reduce the cost."
"Microsoft Exchange Online Protection is a good solution at an affordable price. It is a good investment."
