Featured Reviews

Nasseer Qureshi - PeerSpot reviewer
Pre Sales Consultant at Redington Group
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.

World-class support and highly effective for application control and elevation
Their product is solid. I have a hard time complaining much about it because when we do find little things, they are usually interface-related or related to things that would be nice to have. Their idea portal, unlike so many other vendors we deal with, shows movement. At least four to eight features of ThreatLocker exist because I made a request in the last five years, and it became a feature of the actual product. When it comes to improvements, we moved the product as customers, and we got to move the product by making suggestions. They seem to be very reactive to it, so there is not a whole lot that they actively need to change right now. It is one of those situations where when we run into something that would be nice to have, it happens. They make it work.
