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

"Its analysis or emulation in the review of each file using the cloud and Check Point helps make each interaction via email more secure."
"Over these eighteen months I have been working with the product, it has been very stable, and I would recommend it to most of my peers who have issues related to the email security piece."
"Check Point is a leader in the market."
"The product's environment is easy to work and comprehensive."
"The most valuable feature of the solution is the phishing protection it offers."
"For Threat Prevention, I was impressed with this feature and the solution's effectiveness. It has been very good."
"The product's initial setup phase is very simple and automated. Everything can be made ready within a few clicks."
"The solution helps to block spam emails."
"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

"Check Point should integrate with features available in Barracuda - like more advanced threat management."
"After updates, the internet connection fails, and I have to restart my desktop to resume initial functionalities."
"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."
"There is too much functionality, which makes it difficult to use. More guidance for users would be helpful."
"We have only encountered some false positives that required us to whitelist certain third-party domains, mostly due to their poor email configuration preventing DMARC or SPF alerts."
"Maybe Check Point can work on the DLP part."
"While Check Point Harmony Email and Collaboration offers useful analytics, there is potential for improvement in providing deeper insights."
"The reporting could be improved."
"Policy management with DeviceLock was not very user-friendly."
 

Pricing and Cost Advice

"Being able to keep the phishing campaigns out of my company has been ROI for me."
"Reasonable cost, quick and easy implementation, and transparent."
"The pricing is expensive."
"Due to its pricing, I would say that Check Point Harmony Email & Collaboration is more suitable for medium to enterprise organizations."
"Having information stolen by a hacker would be more expensive than purchasing a license."
"I rate the product's pricing a five on a scale of one to ten, where one is cheap, and ten is expensive."
"The product’s price is very high."
"The pricing is competitive."
