Featured Reviews

Roftiel Constantine - PeerSpot reviewer
Global Chief Information Security Officer at Barry-Wehmiller
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.
MohammedJaffir - PeerSpot reviewer
Founder at Cipheroot
Has enabled me to reduce false positives and perform deep credential auditing with seamless integrations
I mostly use the configuration audit feature for the audit configuration as a scan policy, and I will use it for credential audit, which helps me scan credentials access such as local administrator or root access, performing a deeper and more accurate check of local configuration settings and file systems, making it a highly recommended feature. Regarding integration capabilities, we can integrate Tenable Nessus with SIM tools such as Splunk, IBM QRadar, and Azure Sentinel, as well as with ticketing systems such as ServiceNow, Jira, and Slack. There is no complexity as it is very easy to integrate everything. In terms of the reporting feature, while vulnerability scanning can throw some false positives, Tenable Nessus has very few, achieving a reduction of 75% to 80% false positives with manual analysis needed. We can generate standard Nessus reports that typically include host summaries and vulnerabilities by host and plugin, alongside solutions and remediation recommendations. The main benefits I get from Tenable Nessus are complete asset inventory and comprehensive attack surface management, allowing us to prioritize vulnerabilities based on risk, focusing on true risk and threat path analysis.
