Featured Reviews

Nasseer Qureshi - PeerSpot reviewer
Delivers seamless and secure remote access while enhancing security posture
Check Point Harmony SASE (formerly Perimeter 81) offers strong features, but there are areas that could be improved. One area for improvement is integration with third-party identity providers. It works with standard SAML and SSO, but we would prefer deeper integrations with solutions such as Ping for more advanced identity-based policies. Additionally, a mobile-specific client or lightweight agent would be helpful for securing access from smartphones, especially in BYOD environments. We would appreciate more granular reporting and analytics, including better drill-down capabilities to investigate specific users or app activity. The logs are comprehensive, but filtering them can sometimes feel messy. The user interface on the management portal could be more intuitive, especially when managing multiple sites or remote offices. Some of the policy configuration steps are nested and could be streamlined.
Amber Worth - PeerSpot reviewer
Retrieves data from quarantines and easy to read logs with robust security features
Some of the searchability when looking for specifics in Exchange logs is tedious. Although eventually the information is located, it can be difficult if detailed information is lacking. Improving the search process by allowing searches with different types of parameters and facilitating searches within emails would be advantageous. Simplifying interfaces would also be appreciated.
