Why these ratings?
Cyberse perspective
Summary by Cyberse
Microsoft Sentinel may be considered a good fit for you due to its powerful capabilities.
Here’s a few tips on how to maximize its capabilities:
We use the following criteria to rate this product’s functionality:
Cost considerations
Tenable.io charges per asset like most rivals and includes unlimited vulnerability scans. Separate licenses are needed for web-app, container and analytics modules, so full coverage costs more than the base price. Overall spend ends up around market average rather than offering a distinct cost edge.
Functionality
Tenable.io continuously discovers assets, performs authenticated scans across on-prem, cloud and container workloads, and applies Predictive Prioritization to surface the most exploitable issues. Automatic ServiceNow and Jira ticket creation plus re-scanning to confirm patches align with the rubric’s top functionality tier.
Compatibility
Tenable.io offers agents for Windows, Linux and macOS, native connectors for AWS, Azure, GCP and container registries, and certified integrations that push asset data into ServiceNow CMDB as well as Splunk and QRadar. SAML/OIDC support lets security teams add Tenable.io to existing SSO in minutes. The broad, out-of-the-box hooks remove the need for custom scripts when exchanging data with cloud, CMDB or SIEM platforms.
User experience
Clear asset-centric dashboards with risk and exploitability filters make priority issues obvious and search responds quickly. Most new users complete scans, review findings, and launch guided fixes after a short walkthrough. Some secondary menus appear crowded, so navigation is slightly less intuitive than the very best tools.
Customer support
Tenable.io offers round-the-clock access to trained support staff, so help is available whenever an issue arises. The Nessus plugin feed is usually refreshed within 24 hours of a new CVE, keeping scans aligned with the latest threats. Enterprise subscribers are assigned a dedicated Customer Success Manager who provides proactive guidance beyond reactive ticket work.
