Featured Reviews

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.
Rahul Kamble. - PeerSpot reviewer
Offers complete detection and simple management and is a user-friendly solution
It's very effective as a solution to prevent mobile app threats. It has a mobile MDX, mobile detection, and response session. As a comprehensive solution, Check Point offers a very granular and best-in-class experience. Compared to competitors like Fortinet, Trend Micro, Palo Alto, and Cisco, Check Point provides a superior solution according to both the MITRE and Gartner frameworks. For example, in a recent attack simulation, Check Point only allowed ten malicious emails through, while Fortinet allowed 1500 and Cisco allowed 1800. Check Point's email attack ratio is nearly 0.10%, while others range from 1% to 3%. This demonstrates Check Point's superior email filtering capabilities. Check Point's email cleaning ratio is 99.9%, significantly higher than the 98%, 95%, or 93% of its competitors. Moreover, Check Point Harmony Email incorporates AI technology within its security features. Harmony Email & Collaboration (HEC) provides full protection and addresses zero-day files. It's the best solution available, as others don't offer protection against zero-day attacks and rely on signature-based solutions. HEC is truly the best option.
MOHAN SUKUMAR - PeerSpot reviewer
Secure email management improves through advanced filtering and dynamic virus scanning
Fortinet FortiMail offers capabilities like settings for mail delivery, mail filtering, spam controls, and email bursting prevention. It also allows for email forwarding, dynamic filtering, and scanning based on virus signatures. I can set varying levels of security. The tool is flexible and provides essential features for mail security and management.
