Featured Reviews

Tolu Omolaja - PeerSpot reviewer
Great URL scanning and attachment scanning, but I would like more proactive threat analysis
The two main features that prove most beneficial for us are URL scanning and attachment scanning. URL scanning involves an automatic scan of links and emails. When a user clicks on a link within an email, the system promptly checks the link's safety. If the link is deemed safe, access is granted automatically. However, if it is flagged as unsafe, we receive feedback and notification to caution us about the potentially harmful link. At this point, we are presented with the option to proceed or return. I have personally witnessed the system identify a few unsafe links, making this the primary advantage of using the solution. The second crucial aspect is the scanning of attachments. When an email containing an attachment arrives, we receive a notification of the new email, along with information that the attachment is being scanned for threats. This additional layer of security provides peace of mind for our organization. While Microsoft Defender for Office 365 offers numerous features, these two stand out as particularly impressive and valuable to us.
Roftiel Constantine - PeerSpot reviewer
Provides proactive threat remediation, reduces alert volume, and enhances incident response capabilities
During our pre-purchase evaluation of SentinelOne's EDR capabilities three years ago, we were consistently impressed by the positive relationships customers reported having with SentinelOne's engineers, sales teams, and customer success managers. These strong relationships, evident in the customers' unsolicited feedback, highlighted the "soft skills" and intangible qualities that SentinelOne possessed. This positive customer experience has been mirrored in our own interactions with them. Their responsiveness to our needs, particularly when addressing a couple of challenges we faced, has been excellent. They proactively scheduled weekly meetings to demonstrate their commitment to resolving our issues, a customer-centric approach I admire. SentinelOne's dedication to customer service, including their rapid technology updates and responsiveness to our suggestions, has been crucial to our success in protecting our organization. Their ability to quickly incorporate our needs into new releases is truly impressive and sets them apart. Overall, I highly recommend SentinelOne based on our positive interactions across all levels of their organization.
