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 deployment itself is quite seamless; you can use their temporary licenses for the deployment, just for testing."
"We can say that with Check Point Cloud Guard SaaS, we have improved our security to the next level."
"The stuff that it's picking up and blocking and stopping from coming into our environment has been fantastic."
"Email security has improved since we deployed this platform."
"Our employees and the company's system are pretty much safe, and it has overall improved our email hygiene with very little spam and no malicious attachments reaching us, which get filtered out very quickly."
"The setup is very easy. I haven't faced any complexity with the setup of the solution."
"I can count the number of endpoints, emails, and collaborations being used in the environment."
"The program has a nice interface and it is easy to use."
"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

"I would like the agents to perform better; sometimes, they are too heavy for endpoints, and they affect performance."
"Expanding third-party integration would be beneficial. When I integrate with Microsoft 365, support for other platforms like Slack or Dropbox is limited."
"Stability is the main area that Check Point needs to focus on."
"The implementation could definitely be better."
"Check Point has to continue refining the intelligence engine to minimize the number of false positives."
"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."
"After updates, the internet connection fails, and I have to restart my desktop to resume initial functionalities."
"Support could be improved, as it is only available in English."
"Policy management with DeviceLock was not very user-friendly."
 

Pricing and Cost Advice

"The cost is similar to other competitors. It's not much higher."
"The price is very good, based on what they deliver."
"I rate the platform’s pricing a seven and a half."
"The pricing is in the middle. Check Point's pricing is not the highest in the competitive market."
"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."
"The product’s price is very high."
"The product is expensive compared to some competitors, especially for the SME segment."
"This is a very good product if you are on the cloud, but the price is a little more expensive."
