Tolu Omolaja - PeerSpot reviewer
Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.

The solution enables seamless security management and fosters a learning environment
Feedback could be enhanced. While I work efficiently with Clover as a partner in Mexico City, sometimes the information and requests are easier to manage with more concrete solutions. For the solution stopping us for e-learning, I appreciate the concept yet need more resources or courses in Mexico, preferably in Spanish. Certifications are easy, however, I require more real-world environments and instructors.
Shruti Shetty - PeerSpot reviewer
Automatically protects any files placed within a designated folder, simplifying data protection and ensure continuous data control
The hot folder feature is the most valuable feature of Seclore for safeguarding communications. For example, if an unauthorized user gets access to a file, you can remove their access even if they've forwarded it to someone else. The hot folder feature creates a parent folder that automatically protects any files placed within it. Additionally, when policies are created for third-party applications, files downloaded from them are automatically protected. For instance, pharmaceutical companies generate many files from third-party applications, and Seclore can automatically protect them.
