Featured Reviews

Harish (Kumar) - PeerSpot reviewer
Cybersecurity And Information Governance Head at Aeren
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.

Integrated controls have reduced insider risk and now protect sensitive data across our workforce
One standout feature about Microsoft Purview Data Loss Prevention is the tight integration with Insider Risk Management and Defender XDR, as it gives much better context during investigations instead of treating DLP as an isolated alerting tool. We also use endpoint DLP heavily to control USB, copy, print, clipboard, and browser upload activity, which has been very effective for remote workforce security. The best features Microsoft Purview Data Loss Prevention offers include real-time policy enforcement, endpoint DLP, and deep integration with Microsoft 365 plus Defender XDR. We also heavily rely on sensitive information type detection, adaptive policy tips, and insider risk integration to investigate suspicious user behavior with proper context. Another standout feature is the ability to control USB copy, browser uploads, print clipboards, and cloud sharing actions directly from endpoint policies. The integration with Microsoft Defender 365 and Defender XDR helps our team in day-to-day operations because DLP alerts are automatically correlated with endpoint identity, email, and user activity telemetry, which helps the SOC investigate incidents much faster from a single workflow. The sensitive information type detection makes a difference compared to other tools we have used because it is more effective than many legacy DLP tools. It understands context, exact data patterns, document labeling, and Microsoft 365 native content, reducing false positives while improving detection accuracy. Another strong feature of Microsoft Purview Data Loss Prevention is auto-labeling and policy inheritance with Microsoft's Information Protection, which helps maintain protection even after files are shared or moved across workloads. We also value the user coaching or policy tip capability because it educates users in real time instead of only blocking actions, which reduces repeated DLP violations significantly.
