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.

Controls and limits data transfers to enhance security but network traffic visibility needs improvement
DeviceLock has been problematic and not very effective for us so far, maybe due to configuration issues. It was already in place when I joined and wasn't performing well. We need more control over data, which DeviceLock hasn't provided yet. I remember they moved to Acronis from another company. There were features related to network traffic visibility, which could improve the DLP significantly. Other solutions already offer this kind of network visibility for data loss prevention. They are limited compared to before. Some features were removed from the current version. Policy management with DeviceLock was not very user-friendly. The IT team had to access two servers to make changes. The way the platform and solution are presented requires time to understand and get familiar with.

Quotes from Members

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

Pros

"The product's environment is easy to work and comprehensive."
"I recommend Check Point Harmony Email and Collaboration to all types of companies, from small businesses to enterprises."
"Check Point is a good cloud-based solution with respect to email security, and Check Point is a very powerful tool with respect to other OEMs."
"It is fast and quite effective in terms of preventing any security incidents."
"It has just been phenomenal."
"It seems quite scalable. We don't anticipate any scaling issues. We have it deployed in the cloud."
"The feature I find to be most valuable is very much the zero-touch provisioning. I was able to be up, operational, and 100 percent functional in less than a half an hour."
"The fact that we can share documents without emailing them and still be confident they will go through the corresponding scrutiny is great."
"The most useful feature is the control and limiting of users sending documentation. It works with classification. When you classify your data, DeviceLock identifies it and, depending on your policy, can notify you where the data is going and who's using it."
 

Cons

"There are a few areas for improvement. One is the occasional sluggishness or latency, which is likely due to the cloud-based nature of the solution. So, the performance can be better."
"Check Point's technical support is very much of a low level, especially with respect to other vendors and OEMs."
"Some undefined threats can bypass the security system when there is a networking failure in the organization."
"The solution fails to support hybrid deployments."
"Support could be improved, as it is only available in English."
"Check Point needs to address the pricing segment for SMEs."
"Harmony Email & Collaboration could be improved by making the whitelist available on the website and application level."
"At this time, the two-factor authentication does not work for Active Directory."
"Policy management with DeviceLock was not very user-friendly."
 

Pricing and Cost Advice

"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."
"Do a full feature evaluation (interactive) with a support person. That is what I did."
"I'm in this business as a system integrator, so I need to suggest Check Point to some customers who are comparing products. I sell Check Point, Fortinet, and Palo Alto solutions. In terms of licensing, this solution is quite competitive but very costly. For someone looking at security as a primary concern, they should only invest in Check Point. For a customer who is looking at security combined with pricing, Check Point might not be the core solution for them. In today's market, customers are looking for effective security with efficient pricing, and Check Point is not suitable for these types of customers."
"You can get CloudGuard as part of Infinity. When you do the solution through Infinity, it's a per user type of license cost."
"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."
"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."
"The pricing is competitive."
