NIST RMF: Risk management or bureaucracy?
Read the thread · 51 comments
NIST RMF to Plain Risk Register Translator is a startup idea for security teams, compliance officers, and government contractors. A practitioner finds NIST RMF (SP 800-37) a 'bureaucracy monster in a risk-management costume': the org wants risk-based thinking but must use RMF, and the two don't connect. A thread in r/cybersecurity drew 28 upvotes and 51 comments between Sep 14, 2026 – Oct 14, 2026. People get by with Xacta, Telos, and Spreadsheets, and that still leaves this job open. Hotness is 3.20, Warm. Real but moderate pain. Clear willingness to pay. The thread drew 28 upvotes and 51 comments. Gaps in existing tools. A few weeks of work. A first version is a moderate amount of work, about 3–4 weeks, priced at $200 a month or more and charged as a B2B subscription. The pain, the source, the alternatives, the scope notes, and the questions on this page are free to read and free to build from. The agent starter prompt is the paid part. The first slice is on the page. One credit unlocks the rest, to paste into a coding agent, download as Markdown, or send as a private link.

Market size · estimate
How big this could get
A bottom-up estimate for NIST RMF to Plain Risk Register Translator: real customer counts × a realistic price. Not a forecast.
$231M a year
77,000 contractors · 35% of companies in the US defense industrial base
$69M a year
23,000 contractors · small contractors reachable online
$690K a year
230 contractors · 1% of the reachable segment in three years
What that means
230 contractors at $250/mo = $690K ARR
Medium confidenceHow we estimated this
- Base: 220,000 companies in the US defense industrial base.
- Has the problem: 35% (DoD expects ~76,000 to need a third-party CMMC assessment).
- Revenue per contractor: $3,000 per year ($250/mo).
- Reachable: 30% (small contractors reachable online).
- Three-year capture: 1% of the reachable segment.
TAM = customers with the problem × revenue per customer. SAM = the part an early product can reach. SOM = a conservative three-year share of SAM. Bars use a log scale. Shares marked “assume” are our judgment, not measured.

Is this idea already taken?
People already use Xacta, Telos, Spreadsheets. Those options do not do the job in the solution above. The idea is free to build. Nothing here is an exclusive claim.
How hard is a first version?
Moderate. A tight MVP is about 4 weeks (3–4 weeks), assuming the regulated or partner-gated parts are stubbed. The paid prompt turns that into tasks.
Who would pay, and how?
The audience is security teams, compliance officers, and government contractors. Charge a B2B subscription, and test a price at $200 a month or more. Willingness to pay is one input to Hotness, not a promise that someone will buy.
Can I use the evidence?
Yes. Build the product. The thread title is a short excerpt with a link, not a quote we are putting in someone's mouth. Exact post dates and verbatim lines are added only after a manual check. Ideas are suggestions, not medical, legal, or financial advice.
