TridentStack Control vs Qualys VMDR

Qualys VMDR combines agent and network vulnerability assessment, asset context, and TruRisk prioritization. Qualys also sells patch deployment through Patch Management, as an add-on or within the FixIT bundle. TridentStack Control focuses on managed endpoints and includes patching and DISA STIG scoring in one published price. Run both if network scanning is required.

Where Qualys VMDR is genuinely better

Honest about where the competition wins. If your fleet looks like the cases below, Qualys VMDR is the right answer.

·Qualys combines endpoint agents with network vulnerability assessment, including unauthenticated and authenticated scans. TridentStack Control is an endpoint scanner and does not assess networks, network devices, or unauthenticated hosts.
·Qualys provides asset and threat context through its TruRisk Score, Detection Score, Asset Criticality Score, CVSS, EPSS, and CISA KEV information.
·Qualys sells native patch deployment through Qualys Patch Management. VMDR lists patch detection as included and deployment as an add-on; the FixIT bundle includes patching.
·Qualys publishes VMDR TruRisk starting at $2,195, FixIT at $2,995, and ProtectIT at $4,645. The package page does not state a billing period or asset count, so these figures cannot be compared as per-endpoint prices.
·Qualys has a hosted SaaS platform and documents an on-premises private-cloud option for customers that need an internal platform.

Where TridentStack Control is genuinely better

The capabilities that don't exist in Qualys VMDR or only exist as separate paid SKUs.

·The first 200 endpoints are free forever for commercial use, with every feature included, and the per-endpoint price past 200 is published.
·TridentStack Control continuously detects endpoint vulnerabilities from software inventory rather than waiting for scheduled network sweeps.
·Endpoint patch deployment for operating systems and third-party applications is included in the same price as vulnerability detection, without a patch-management add-on or bundle decision.
·DISA STIG scoring for supported Windows, macOS, Ubuntu LTS, and RHEL endpoints is included, along with Microsoft Security Baselines for Windows. STIG results map to NIST 800-53 as a reporting view, not a scored NIST baseline.
·TridentStack Control is hosted, uses outbound agent connections on port 443, includes MSP multi-tenancy, and provides vendor email support on every endpoint, including free endpoints.
·Findings carry CVSS, EPSS, and CISA KEV status and are grouped by the update that fixes them, with exception expiry and an audit trail.

How to migrate from Qualys VMDR to TridentStack Control

A plain-language sequence. Skip the steps that don't apply to your fleet.

1
Keep Qualys network scanning where you need it
TridentStack Control does not scan networks, unauthenticated hosts, network devices, web applications, containers, or cloud configurations. Keep Qualys for network, device, and web application assessment, or operate both products with separate roles.
2
Install the TridentStack Control agent on a pilot group
Choose a representative group of supported Windows, macOS, and Linux endpoints. Keep Qualys agents and configured network scans active while you compare software inventory and endpoint findings.
3
Compare prioritization and patch coverage
Compare CVSS, EPSS, and CISA KEV status and review how each product relates a finding to remediation. TridentStack Control groups endpoint findings by the update that fixes them; Qualys provides TruRisk context and patch deployment through its licensed Patch Management options.
4
Move selected endpoint patching into deployment rings
If TridentStack Control fits your endpoint workflow, configure approval rules and deployment rings for operating system and third-party application patches. Retain Qualys Patch Management if its workflows remain necessary, and keep Qualys for network assessment.

Frequently asked questions about Qualys VMDR and TridentStack Control

Does TridentStack Control replace a network scanner?

No. TridentStack Control detects vulnerabilities on managed endpoints from software inventory. It does not scan networks, unauthenticated hosts, network devices, hypervisors, web applications, containers, or cloud configurations. Keep Qualys for network assessment, or run both products and use TridentStack Control for endpoint detection and patch deployment.

Can Qualys VMDR deploy patches?

Yes. Qualys Patch Management deploys patches to Windows, Linux, and Mac assets. VMDR lists patch detection as included and patch deployment as an add-on; the FixIT bundle includes patching. TridentStack Control includes operating system and third-party application patch deployment in its price.

What do Qualys VMDR packages cost?

Qualys lists VMDR TruRisk starting at $2,195, FixIT at $2,995, and ProtectIT at $4,645. The package page does not state a billing period or asset quantity, so those figures cannot be converted to a per-endpoint price. A 7-day package trial is listed; a separate VMDR plus Patch Management offer advertises a 30-day trial.

Does Qualys include DISA STIG scoring in VMDR?

Qualys supports DISA STIG benchmarks through Policy Audit, and the VMDR feature table lists Policy Compliance as an add-on. TridentStack Control includes DISA STIG scoring for supported endpoints.

How are the products deployed?

Qualys offers a SaaS platform and an on-premises private-cloud option, and internal network scans can use a customer-deployed virtual scanner. TridentStack Control is hosted and its agents connect outbound on port 443. Neither deployment model changes TridentStack Control's endpoint-only scanning scope.
