An AI feature that helps them discover options without requiring them to deep dive into all features or guides them through advisory functions would be beneficial.

Valuable Features

Tenable Nessus excels in vulnerability detection, user-friendliness, scalability, real-time monitoring, integration, compliance reporting, and remediation advice.
Wiz provides robust cloud security with advanced risk analysis, user-friendly interface, AI, and comprehensive multi-cloud integration.
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.

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.
Peter Whelan - PeerSpot reviewer
CISO at a computer software company with 1,001-5,000 employees
Improved our security posture thanks to comprehensive visibility
I have contacted Wiz technical support frequently. The support is excellent. We contact via an in-application portal. We can see the support cases we personally open, and also the cases that other people have opened from our company. I appreciate that feature. Generally, support gets back to us within a few days with a good answer. There was one fellow in particular who has been knocking it out of the park. He is a great support person to deal with. We are happy with the support experience. If I were to put Wiz support on a scale from one to ten, I would give them a ten.
