Assistant Vice President, Tech Solutions at LPL Financials
Has simplified remote software delivery and script management but needs improved reporting flexibility and better Mac support
NinjaOne's best features include ease of use regarding enablement and deployment, a broad selection and ability of software enablement, and API deliveries. Using CrowdStrike, we are able to tie in NinjaOne's API to have these automatically deliver to endpoints upon addition of those devices to a group with that policy deployed to it. NinjaOne has positively impacted our organization by making delivery easier for our end users and improving the ability to create scripts, manage scripts, and check status of devices and their compliance. This easier delivery with NinjaOne gives us oversight on devices without having to be on the call or remoted in directly to a device.

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.
