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.

Strengthens cross-platform threat response while supporting audit compliance and log integration
The analytics and reporting can be a bit overwhelming. I love the dashboards, but I find that I need to better understand PowerQuery—specifically when to turn it on and off and its limitations. It's similar to SharePoint in that regard. As a former SharePoint instructor, I know it like the back of my hand. The best thing about SharePoint is that it can do whatever you want; the worst part is also that it can do whatever you want. You really need to know what you want before diving in. Most people usually have a good idea of what they need. SharePoint offers a lot out of the box, but you can customize it further if you wish. However, customization often requires hiring someone, which can be risky since you never know if it will work as intended. On the other hand, PowerQuery can help bridge some of those gaps within Singularity. The challenge arises when you want to incorporate what you've done into dashboards and charts, as there are limitations. For instance, I want more clickable drill-down options that allow me to filter on specific sections of the data, but that's currently not possible. It’s not to say that improvements won’t come in the future; it's just that it feels a bit early at this stage. Additionally, I find some navigation features frustrating, like the back button in certain contexts. For example, if you open PowerQuery from a chart, it doesn't open in a new window or tab. Clicking the back button takes you all the way back to the previous state, causing you to lose whatever progress you made. However, I'm actively providing this feedback to my partner, Pro Circular, through whom we access SentinelOne. They take our input seriously, and I've been sharing my observations. They have their own views but are addressing the issues I raise. It's good to see that suggestions occasionally lead to updates and improvements.
