Rules can change, so Rankhog keeps verification dates and the original public Reddit sources visible.
Rule summary
- Keep it professional: Keep it professional. This doesn't need further explanation.
- Complaints: This subreddit is not a democracy, it is a dictatorship. If you don't like the rules please send your complaints to the DoD CIO.
- No Direct Advertising, With Exception: Vendors are not permitted to directly advertise themselves. That means, no posts linking to your company blog or soliciting the business of community members. Vendors are encouraged to engage with the community, and are advised to use a soft touch when mentioning their services. There will be occasional exceptions to this rule made by the moderation team WHEN: A vendor brings an original content post that adds value to the community.
- DM'ing members: Vendors are prohibited from directly DM'ing people unsolicited. Any vendor found DM'ing people directly with "Hey I can do this for you, what's your email" will be banned.
- No Unexplained Blogs or External Content: Blog posts, clickbait articles, youtube videos and other external content is only allowed when the poster provides context, and the external content provides value to the community. Low effort clickbait will result in an immediate ban. Please keep your "2 Easy Steps for Total Compliance" articles to your mailing lists.
- 6. No AI slop: Put in the work and actually write your thoughts without having AI do the work for you
Works well
- A detailed post explaining one specific part of the CMMC final rule in plain language, written entirely in your own words.
- A firsthand account of implementing a specific CMMC control, sharing what worked and what did not, with no link to your company.
- A question about a confusing part of the CMMC requirements that shows you have done your homework and explains what you already tried to understand.
- A text post that compares two approaches to meeting a CMMC requirement, written from real experience, with a brief soft mention of your services only if it fits naturally.
Avoid
- Posting a link to your company blog with no context or explanation, which breaks the rule named No Unexplained Blogs or External Content.
- Sending unsolicited direct messages to community members offering your services, which breaks the rule named DM'ing members and leads to a ban.
- Using AI tools to generate your posts or comments, which breaks the rule named 6. No AI slop.
- Writing low effort clickbait style articles like quick compliance checklists, which the rules explicitly call out as ban worthy.
- Posting anything unprofessional, which breaks the rule named Keep it professional.

What r/CMMC Is For
This community is for members seeking information, guidance, and assistance for meeting the DoD CMMC rating guidelines. It is a professional space focused on the Cybersecurity Maturity Model Certification program, and it points people to the final rule published in the Federal Register. The community also connects to a Discord server and sister subreddits focused on NIST controls, government IT, and Azure Government. People posting here are likely compliance professionals, contractors, consultants, and vendors who work with or need to meet CMMC requirements.
Rules That Matter Before Posting
The rule named Keep it professional sets the tone for everything. The rule named No Direct Advertising, With Exception is the one that matters most for vendors, because it says you cannot link to your company blog or solicit business, but you can post original content that adds value if the moderators approve. The rule named No Unexplained Blogs or External Content means you cannot just drop a link, you must provide context and the content must genuinely help people. The rule named DM'ing members is a hard line, and the rule named 6. No AI slop means you must write your own thoughts without AI generating them for you.
What To Post
A good post here is something you wrote yourself, in your own words, that helps people understand or navigate CMMC requirements. If you are a vendor, the only way to share your expertise is through an original content post that adds real value to the community, with a soft touch when mentioning your services. If you share an external link, you must write a clear explanation of why it matters to the community. Think deep dives on specific CMMC controls, lessons learned from a real implementation, or a thoughtful breakdown of part of the final rule. The community wants substance, not promotion.
What To Avoid
Avoid any direct advertising of your company or services. The rule named No Direct Advertising, With Exception is clear that linking to your company blog or soliciting business is not permitted. Do not send unsolicited direct messages to members, because the rule named DM'ing members says any vendor caught doing this will be banned. Do not post unexplained blog links or external content without context, because the rule named No Unexplained Blogs or External Content says low effort clickbait results in an immediate ban. Do not use AI to write your posts, because the rule named 6. No AI slop prohibits it. And keep everything professional, as the rule named Keep it professional requires.

Common questions about r/CMMC
Can I DM community members to offer my services?
No. The rule named DM'ing members prohibits vendors from directly messaging people unsolicited, and doing so will get you banned.
Can I use AI to help write my post?
No. The rule named 6. No AI slop requires you to write your own thoughts without AI doing the work.
What kind of external content is allowed?
You can share external content only when you provide context explaining its value to the community, and the content itself must genuinely add value.
Can I promote my CMMC consulting services here?
No. The rule named No Direct Advertising, With Exception says vendors are not permitted to directly advertise themselves or solicit business from community members.
