CertiField vs SteelCloud ConfigOS

They do different jobs and neither replaces the other. ConfigOS changes the configuration of your systems so they comply with STIG baselines. CertiField records what the system is and what its controls do. ConfigOS output is an input to CertiField.

What SteelCloud ConfigOS is.

ConfigOS is SteelCloud's compliance automation product for STIGs, CIS Benchmarks and CMMC. SteelCloud describes it as automating system hardening, remediation, continuous monitoring and compliance reporting — adapting policy, documenting the controls that conflict with an application stack and need to be waivered, creating RMF artifacts and integrating that information into STIG Viewer. It operates without requiring internet access, domain controllers or Active Directory, which SteelCloud markets as suited to air-gapped labs and to systems running off-network or across degraded links. It is listed on the DoD Approved Products List and the CDM APL, and is approved for use on NIPRNet, SIPRNet and JWICS.

CertiField is an operational RMF layer. It holds one authorization record per system and generates the SSP, SAR, POA&M, OSCAL output and authorization package from it.

Stated: August 26, 2026

Which one fits the problem you have.

Which tool fits depends on the shape of your program — how often the system changes, who owns the authorization, and what your submission path already is.

When SteelCloud ConfigOS is the right answer

Your hosts are not consistently hardened, or STIG results vary across the fleet.
You need remediation applied at scale rather than findings cataloged.
You need waiver and exception handling at the configuration layer, with rationale recorded.
You are operating in a disconnected enclave and need hardening that works there.

When CertiField is the right answer

Your hosts are in reasonable shape and the gap is that nobody can assemble a current authorization package from what you have.
The SSP is out of date, nobody knows which assessment result is current, and a system change means a week of reconciliation.
STIG results, scan output and pipeline evidence need to reach the controls and CCIs they bear on.
Findings need to become POA&M items with a link back to the checklist item that produced them.

Using both

This is the intended arrangement rather than a choice. CertiField determines which DISA STIGs apply to the technologies your system actually runs; ConfigOS acts on those baselines and hardens the estate; the resulting checklist results and waiver rationale come back as evidence bound to the CCIs and controls they support; and what remains unremediated becomes tracked POA&M with its lineage intact. A program running both is in a better position than one running either alone.

These are not alternatives

This page exists because the two products appear in the same searches, not because anyone should be choosing between them. Putting them side by side is useful mainly for showing where the boundary between two jobs sits.

ConfigOS changes your systems. It takes a STIG or CIS baseline, scans hosts against it, applies remediation, handles the waivers and exceptions for settings that cannot be applied, and reports what the estate now looks like. The output is a fleet in a known configuration state.

CertiField records what your system is. Boundary, components, control implementations, evidence, assessments, determinations, findings, POA&M items — and the SSP, SAR, POA&M and authorization package generated from all of it. The output is a defensible authorization record.

One of those is an actuator. The other is a ledger. Different jobs, and the pipeline between them runs one direction.

How they compose

Worth walking through, because the handoff is where most programs lose fidelity today.

Applicability is determined. Given the technologies the system actually runs, which DISA STIGs apply? This is the question that gets guessed at.
Hardening happens against the applicable baselines. Remediation is applied, and the settings that could not be applied are recorded along with why.
Results come back as evidence. Checklist results — CKL or CKLB — and waiver rationale land against the CCIs and controls they bear on.
What remains is carried. Unremediated findings become POA&M items with a link back to the checklist item that produced them, and the whole thing exports to eMASS.

What many programs do instead is step 2, then a person, then a spreadsheet, then a different person, then eMASS. The information survives that journey; the traceability does not.

Why the distinction matters when you are buying

Configuration compliance and control compliance get conflated constantly, and the conflation is expensive in both directions.

A hardened fleet is not an authorization. STIG compliance addresses a specific and important slice of the control set — largely configuration management, technical access control and audit — and does not speak to your contingency plan, your interconnection agreements, your personnel security or your system categorization. A program that hardens well and cannot produce a coherent SSP will not get an ATO.

Equally, an immaculate SSP describing a fleet nobody hardened is a document about a system that does not exist. The evidence has to come from somewhere real.

The two gaps look nothing alike, and closing one does not close the other.

If you only have budget for one

An honest answer: it depends which gap you currently have.

If your hosts are not consistently hardened and your STIG results are inconsistent, fix that first. Evidence has to be true before it is worth recording well, and a tool that faithfully records inconsistent configuration state has given you a well-organized problem.

If your hosts are in good shape and the pain is that nobody can assemble a current package from what you have, the record is the gap.

Ask: every vendor, us included

Ask for the demonstration, not the claim.

The most reliable way to compare tools is to make each vendor show you the same things in a live product. Ask us these too — if we cannot do one of them, that is worth knowing before you buy.

01 Show me the applicable STIG list for this technology stack, and where it came from. Applicability is the handoff point between the two jobs. Guessing high costs weeks assessing rules that do not apply; guessing low costs a finding.
02 Import a CKLB, then import a newer revision of the same STIG. Whether prior review comments and dispositions survive the merge is what decides whether your checklists stay current or quietly stop being updated.
03 Take an open STIG finding through to a POA&M item. The link from a checklist item to tracked remediation is the one a reviewer follows, and it is where most processes lose the thread.

CertiField vs eMASS

They are not alternatives. eMASS is the government system of record that receives authorization data and where the AO makes the decision. CertiField is the operational layer where that data is produced, kept current and generated into artifacts, then exported to eMASS.

CertiField vs Xacta

Xacta is a broad, established federal compliance and authorization platform that many organizations run as their authorization repository. CertiField is narrower by design — one DoD system boundary, anchored to engineering evidence and architecture change — and is built to feed a repository rather than replace one.

CertiField vs RegScale

Both start from the same complaint — that authorization packages go stale — and both take OSCAL seriously. RegScale is a multi-framework compliance automation platform. CertiField is scoped to DoD RMF operations on one boundary and anchored to an architecture model.

CertiField vs generic GRC platforms

GRC platforms are built to govern controls, risk and policy across an organization and across frameworks. DoD RMF adds specific machinery — CCI-level assessment, DISA STIG revisions, FIPS 199, an SP 800-37 package, an eMASS submission — that is worth verifying explicitly rather than inferring from a framework list.

CertiField vs manual RMF

Manual RMF produces real ATOs and the people doing it are usually competent and under-resourced. What it cannot do cheaply is absorb change — every system change forces a human reconciliation whose reasoning is never retained, so it is paid for again every time.
