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 sanitization feature of Check Point Harmony Email and Collaboration is valuable."
"As Check Point is a leading technology in the industry, it provides maximum protection against email phishing attacks and provides the identity of users and visibility over shadow IT applications."
"Checkpoint Harmony Email and Collaboration has significantly improved our email security by effectively blocking phishing, malware and ransomware threats."
"After the implementation of the solution, email phishing is stopped and gives complete visibility."
"It has just been phenomenal."
"The most valuable feature of the solution is the phishing protection it offers."
"We can say that with Check Point Cloud Guard SaaS, we have improved our security to the next level."
"The most valuable features would be its ability to intercept phishing emails and emails laden with malware, viruses, false links, etc."
"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 could be more automation features included for it."
"I chose nine because I'm not quite sure anything is a ten; I don't really know how to answer that, but the ten leaves room for improvement."
"Stability has been a pain point. I was going back and forth with my product engineer and project manager for a couple of months. I had the product in a demonstration mode and wasn't satisfied with the results initially. After a few alterations and a few revisions later, it is fine."
"They must provide security to more email service providers."
"The only area for improvement is the language of the support. The support is only available in English."
"There is a need for improvement in handling business email compromise."
"We have used technical support, but their response time is very slow. It needs to be improved."
"Some undefined threats can bypass the security system when there is a networking failure in the organization."
"Policy management with DeviceLock was not very user-friendly."
 

Pricing and Cost Advice

"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."
"Cost is the main concern that every customer takes into consideration, and Check Point always negotiates a price that is affordable."
"You can get CloudGuard as part of Infinity. When you do the solution through Infinity, it's a per user type of license cost."
"Being able to keep the phishing campaigns out of my company has been ROI for me."
"The difference between [Check Point and its competitors] boiled down to money. Price-wise, Check Point was very good, it was very competitive."
"Due to its pricing, I would say that Check Point Harmony Email & Collaboration is more suitable for medium to enterprise organizations."
"The cost is similar to other competitors. It's not much higher."
"The pricing is in the middle. Check Point's pricing is not the highest in the competitive market."
