Sreeraj Mohandas - PeerSpot reviewer
Security Engineer at HashXpert
Consolidated cloud security has reduced manual work and has automated vulnerability remediation
I elaborate on my rating of SentinelOne support by mentioning that there was some time where the troubleshooting took a longer time. In fact, there were many meetings going on. The availability of the document on the internet is on a lesser side because as an engineer, I would want to know about the troubleshooting aspects of this particular tool. When I am facing a customer, I do not prefer to bring the vendor to every call and try to resolve it, as it takes months and months. It would be better to have a training session with the engineer on site to explain and train properly. This is not the case with SentinelOne, so this is the only thing I have a complaint about. I do not have any other room for improvement to suggest within SentinelOne itself. However, I would really want the AI assistant for the threat hunting part to be more accessible. They have it, but they are making it licensed, so it is a bit on the higher end.
Nasseer Qureshi - PeerSpot reviewer
Pre Sales Consultant at Redington Group
Email security effectively detects a wide range of threats and improves productivity
Since we have been using Check Point Harmony Email & Collaboration for a year, we haven't encountered significant challenges. However, it would be beneficial if it could support other email security services beyond Microsoft and Google. Integration with other platforms would enhance its appeal since the features are commendable. While the analytics are commendable, they don't provide deep dive insights. They show the overall counts of malware, phishing, and business compromise emails, but there isn't a robust ability to dive deeper into those categories to see specifics. Analytics should allow us to explore which users received malware emails the most or trends among departments. Currently, we have to sift through manually, which is not ideal. A more profound analytical capability would elevate the tool to become the complete email security solution for any user.
Irfan Sharfi - PeerSpot reviewer
Security Professional at a tech vendor with 10,001+ employees
Micro-segmentation has transformed endpoint protection and now isolates internal threats effectively
Illumio can be improved in several areas based on our feedback. Sometimes, the PCE experiences slowness, especially when deploying around 300,000 endpoint devices. When these devices communicate within the network, loading the map or connections can cause latency, which needs improvement for a more user-friendly and faster experience. Regarding improvements to the interface, I believe we can add more features to the graphical user interface, such as proper logs. While the logs currently indicate what was blocked or allowed, clicking on a specific log should provide more information, such as which extra-scope rule is causing a denial, offering better analysis for troubleshooting.
