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.

Layered email security has protected sensitive research and still flags phishing in real time
The valuable features of Microsoft Exchange Online Protection (EOP) include providing an additional layer of protection, as it builds on the basic Exchange level of security that allows us to get our work done. Another feature I appreciate is the ability to question things, as our Exchange server allows us to identify in real-time if an email is a phishing email or spam email. It really helps us identify risks, especially through our external exchanges via email or through our cloud-based platforms. Our Exchange system blocks any embedded AI from all our applications and products, so we cannot use embedded AI in our daily work from our official laptops because we have secure information. The system is quite locked down.
