Tenable is the gold standard for vulnerability discovery, and its base scanning costs less per asset than Mantis360. Mantis360 is built for breadth: vulnerability management on one cloud-delivered platform with MantisRMM and MantisNMS, with OT/ICS detection and identity/AD exposure checks included and monthly billing.
Mantis360 shares one agent, tenant, console and bill with MantisRMM endpoint management and MantisNMS network monitoring. RMM software inventory feeds CVE correlation, and one on-site collector powers both network discovery and monitoring. Bundle all three and save 10%.
ICS/OT device detection matched against CISA ICS advisories, Active Directory exposure checks and external posture grading are part of every Mantis360 asset pack. Tenable now includes OT discovery in Vulnerability Management, but licenses full OT Security, Tenable Identity Exposure and attack-surface management as separate products.
$4 per asset per month, starting from a single 50-asset pack, with no annual contract — cancel anytime. Tenable Vulnerability Management is sold on 1- to 3-year subscriptions, from 100 assets online.
Nothing to host: a lightweight agent and an optional on-site probe report to the cloud. Findings close on the agent's next check-in, are ranked by CVSS × EPSS, and anything on CISA's Known Exploited list is escalated automatically.

Tenable's base scanning costs less per asset than Mantis360. For enterprise-scale compliance with regulatory reporting, Tenable has deeper certification breadth (including a FedRAMP Moderate environment), and its VPR prioritization is well proven. If base scanning price or those strengths matter most, Tenable may suit you better.
Identity/AD exposure checks, external attack-surface posture grading and ICS/OT detection matched against CISA ICS advisories are included with every Mantis360 asset pack. Tenable licenses Tenable Identity Exposure, attack-surface management, full OT Security and patch management as separate, quote-only products. Mantis360 also runs on the same platform, agent and bill as MantisRMM and MantisNMS.
Not on base scanning. For 100 assets Tenable Vulnerability Management lists at about $3,500–$3,700 a year on a 1-year term; Mantis360 is about $4,800 a year, billed monthly with no contract. Mantis360's price includes identity/AD, attack-surface and OT checks that Tenable sells as separate, quote-only products, so which costs less depends on which of those you need.
Every time the agent checks in, Mantis360 compares the installed software with open findings. When the vulnerable software is gone, the finding is closed as auto-remediated with a timestamp and audit entry — no manual ticket clean-up.
It uses a lightweight agent on Windows, Linux and macOS for software inventory, and an on-premises probe for agentless network discovery and scanning.
