Comparison
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.

What RegScale is.
RegScale is a commercial continuous controls monitoring and compliance automation platform. It is OSCAL-native — RegScale is a founding member of the NIST OSCAL Foundation — and states native support for more than sixty regulations and frameworks including NIST SP 800-53, FedRAMP, FISMA, CMMC, PCI DSS, SOC 2 and others. It is delivered as a multi-tenant SaaS offering built on Microsoft Azure and listed on the FedRAMP Marketplace, and it markets API-driven integrations for managing controls, uploading evidence, performing system assessments and maintaining certifications and authorizations, with an emphasis on FedRAMP, FISMA and RMF, ATO and continuous ATO, and CMMC for government contractors.
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.

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 RegScale is the right answer
- You are multi-framework — FedRAMP, CMMC, 800-53 and others under one program.
- The compliance program spans more than DoD systems, and consistency across them is the requirement.
- The buyer is a compliance function responsible for a portfolio rather than a single engineering program.
- OSCAL-native operation across that whole portfolio is the outcome you are buying.
When CertiField is the right answer
- The work is DoD RMF specifically, with CCI-level assessment, DISA STIG applicability and checklist revisions as first-class machinery.
- An eMASS round trip is part of your life and you want it built rather than exported to.
- Reassessment scope after an architecture change is a recurring argument you want computed.
- You need to run with no outbound path, with a local model or with AI switched off entirely.
Using both
There is genuine overlap here and we will not pretend otherwise — this is the most direct comparison on the site. Most organizations would run one or the other for a given system rather than both. If your estate is broader than DoD, that breadth is a real requirement and should weigh heavily.

The shared premise
RegScale and CertiField agree about what is broken, which makes this a more interesting comparison than most.
Both argue that a compliance package produced as a point-in-time document is obsolete before it is reviewed. Both argue the fix is a machine-readable record that stays current, rather than a faster way to produce the same stale document. Both take OSCAL seriously rather than treating it as an export checkbox.
That is real agreement and it is worth saying plainly. Where we differ is scope and anchoring.
Breadth is a real requirement, when it is one
RegScale spans frameworks — 800-53, FedRAMP, CMMC and others — and sells to federal, defense and regulated commercial buyers. CertiField does DoD RMF. Not “RMF among other frameworks”: DoD RMF, with CCIs, DISA STIGs, FIPS 199 and an eMASS submission assumed at the end of the road.
If you need one platform carrying a FedRAMP authorization, a CMMC assessment and an internal risk program alongside your DoD systems, breadth is the requirement and you should weight it heavily. That is a scenario where we are the wrong shape and we would rather say so than waste your evaluation cycle.
If your problem is one DoD boundary that will not stop changing, breadth is not what you are buying.
What the record is anchored to
This is the deeper difference and it is easy to miss.
Continuous controls monitoring anchors the record to control state: is this control still implemented, is the evidence still fresh, has something drifted. That is a genuinely valuable frame and CertiField does it too.
CertiField additionally anchors to system architecture. The authorization boundary, its trust zones, components, connections, data flows and interconnections are modeled as structured facts and published as immutable, content-hashed versions. When the system changes, the change is a diff between two versions, and the reassessment scope is derived from the diff rather than declared by a person.
That addresses a question control-state monitoring is not aimed at: not “has this control drifted?” but “we just moved a component across a trust boundary — which controls does that make questionable, and what has to be reassessed?”
OSCAL, and the test that settles it
Both products speak OSCAL. It is worth being precise about what that buys, because OSCAL is easy to claim and harder to mean.
The test is whether the human-readable and machine-readable outputs are two renderings of one record or two separately maintained artifacts. If the DOCX and the OSCAL can disagree, OSCAL is an export format. If they cannot, because both are generated from the same facts, OSCAL is the record’s native shape.
Ask both vendors to change a fact, regenerate both outputs, and show the change in each. It is a two-minute demonstration and it settles the question for either of us.

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 Change a fact, then regenerate both the OSCAL and the human-readable document. If both change, OSCAL is the record's native shape. If they can diverge, it is an export format, and a consumer has no way to know which is current.
- 02 Show me a CCI-level assessment result under a single control, with different outcomes per CCI. DoD assessment happens below the control. A single status per control forces the detail into a comment field.
- 03 Import a newer revision of a STIG we have already assessed. Whether prior review comments survive the merge determines whether updating a checklist costs a review of what changed or a full re-review.
- 04 Change the architecture. Show me the reassessment scope and where it came from. The derivation matters more than the number. You want to see the reasoning, not a total.

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 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.
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.
