Short answer: DISA STIG compliance checking does not have to be a manual, per-machine exercise. An agent-based platform can score every endpoint in a fleet against its applicable STIGs, track findings over time, and tie the results to the same tool that patches the machines. No CAC required, no scanner infrastructure to run.
What STIG compliance automation replaces
The traditional STIG workflow involves three tools and a lot of manual effort:
- Download the benchmark. STIGs ship as XCCDF XML from DISA's public library. You pick the right STIG for each OS and application version.
- Run the scanner. SCAP Compliance Checker (SCC) or OpenSCAP evaluates the controls against a target machine. Each scan produces an XML or HTML report for that one endpoint.
- Record the findings. STIG Viewer manages the per-target checklists: open, not a finding, not applicable, with justification text per control.
For a small lab this works. For a production fleet, the per-machine overhead becomes the bottleneck. No central dashboard. No trend line showing whether compliance is improving or regressing. No connection between "this control failed" and "here is the patch or setting that fixes it."
STIG compliance automation moves the evaluation onto a lightweight agent that reports results to a central console. The console scores the fleet, tracks trends, surfaces per-control evidence, and connects findings to the patching and policy tools that close them.
What to look for in a STIG automation tool
Not every tool that mentions STIGs automates the same things. The useful questions when evaluating:
- Does it score continuously or on demand? A point-in-time scan tells you the state at the moment you ran it. Continuous evaluation catches drift between scans.
- Does it cover your OS mix? Windows STIGs, macOS STIGs, and Linux STIGs (Ubuntu, RHEL) are separate benchmarks. A tool that only covers Windows leaves half the fleet unscored.
- Does it produce per-control evidence? An aggregate score is a start. Per-control pass/fail/not-applicable with the actual registry key, file permission, or configuration value is what an auditor or assessor needs.
- Does it connect findings to remediation? Knowing a control failed is useful. Having the patching or policy tool that fixes it in the same console is the difference between a report and a workflow.
- Does it map to NIST controls? DISA STIGs carry CCI mappings to NIST SP 800-53. A tool that surfaces the mapping lets you report to both frameworks from one evaluation.
- Does it require a CAC or government account? STIGs are public documents. A tool should ship the benchmarks without requiring you to obtain and manage DISA credentials.
How TridentStack Control automates STIG compliance
TridentStack Control installs one agent per endpoint. The agent evaluates the applicable DISA STIG controls and Microsoft Security Baseline settings, then reports the results to the cloud console.
The console provides:
- Fleet-wide compliance scoring with per-endpoint drill-down and per-control evidence.
- Trend tracking that shows whether compliance is improving, regressing, or holding steady over time.
- NIST 800-53 mapping derived from the CCI mappings that every DISA STIG control carries, plus 800-171 Rev 3 and CSF 2.0 crosswalks.
- Patch management and policy management in the same platform, so a failed control that requires a missing update or a changed setting can be fixed without switching tools.
Supported benchmarks: DISA STIGs for Windows (10, 11, Server 2016 through 2025, Edge, Defender Firewall), macOS, Ubuntu 20.04/22.04/24.04 LTS, and RHEL 8/9. Microsoft Security Baselines for Windows 10 22H2, 11 23H2, and 11 24H2.
Pricing: the first 200 endpoints are free forever, then 5 dollars per endpoint per month with every feature included.

Compared to other free or low-cost STIG tools
For a detailed side-by-side, see the free DISA STIG compliance tool comparison. The short version:
| Tool | Fleet scoring | Trend tracking | Ties to patching | Web console | Free limit |
|---|---|---|---|---|---|
| TridentStack Control | Yes | Yes | Yes | Yes | 200 endpoints |
| STIG Viewer 3 | No | No | No | No | Unlimited (desktop) |
| SCC (SCAP Compliance Checker) | No | No | No | No | Unlimited (desktop) |
| OpenSCAP + SSG | No | No | No | No | Unlimited (self-hosted) |
| Wazuh SCA | Per-agent | No | No | Yes (self-hosted) | Unlimited (self-hosted) |
STIG Viewer and SCC are capable tools for per-target work. OpenSCAP is a solid open-source scanner. Wazuh provides a self-hosted dashboard with per-agent scoring. None of them connect the compliance finding to the patching action, and none provide fleet-wide trend tracking without additional tooling.
Who this is for
- DoD contractors and the Defense Industrial Base preparing for CMMC assessments or maintaining NIST 800-171 evidence through DISA STIG evaluations.
- IT teams in regulated industries that use STIGs as a hardening baseline even outside the federal space.
- MSPs managing compliance for multiple clients, where per-tenant scoring and reporting from one console eliminates per-client tool sprawl.
- Anyone who inherited a fleet of STIG checklists in Excel and wants to stop copying control findings by hand.
