NIST SP 800-171 Rev 3C5 (Germany)

NIST SP 800-171 Rev 3 covers 50.4% of C5 (Germany)

61 of the 121 controls in C5 (Germany) are already satisfied by evidence you collected for NIST SP 800-171 Rev 3. 60 are genuine gaps. Every claim below was judged against both control sets and then argued against; the ones that did not survive are published further down with the reason each failed.

What this leaves you to do

C5 (Germany) has 121 controls. Holding NIST SP 800-171 Rev 3 already evidences 61 of them, so the work in front of you is 60 controls, not 121, which is 50% of the standard rather than all of it.

That is the whole claim. Every number in that sentence comes from the two counts above it and can be re-derived from the free tools without taking our word for any of it.

In money, using only our numbers. The full report is $299 and names 61 controls of C5 (Germany) you do not have to implement again, which is $4.90 per control identified. That arithmetic uses our price and our count and assumes nothing about you.

In your hours, using your assumption. We do not know what a control costs you to implement, so pick the column that looks like your organisation. These are your figures, not our claim.

If a control takes you4 hours8 hours16 hours
the 61 already evidenced are244 hours488 hours976 hours
and the 60 remaining are240 hours480 hours960 hours

Multiply by your own rate. We publish no rate because we have not measured yours, and a number built on an invented rate is the kind of claim this platform exists to argue against.

This number is directional. It says how much of C5 (Germany) your NIST SP 800-171 Rev 3 evidence satisfies. The reverse pair is a different number, often very different, because a security standard has enormous depth for access control and almost none for lawful basis or data subject rights.

120 candidate mappings were examined and 0 were removed. Signed off 2026-08-19, review level machine verified. Mappings were judged by Claude Code rather than read line by line by a practitioner. Every claim shows its reasoning so you can check it. Ask and a practitioner will review this pair.

Where the gaps are

Coverage is never evenly spread. A source standard usually satisfies one part of a target almost completely and barely touches another, and which part is which is the thing worth knowing before you plan the work.

Theme level, not control level, deliberately. The per-control list of what is evidenced and what is a gap is the report itself, so publishing it here would be publishing the thing being sold.

Claims that held

A sample. Each one names the control whose evidence does the work, the control it satisfies, and why.

03.04.10C5-AM-01argued against and upheld
Asset Inventory

Component inventory developed, documented and reviewed to stay current and accurate.

03.15.03C5-AM-02argued against and upheld
Acceptable Use and Safe Handling of Assets Policy

Rules of behavior describe user responsibilities and are acknowledged before access.

03.08.03C5-AM-04argued against and upheld
Decommissioning of Hardware

Media sanitized or destroyed before disposal, release or reuse, with verification.

03.15.03C5-AM-05argued against and upheld
Commitment to Permissible Use, Safe Handling and Return of Assets

Acknowledgment of rules of behavior is required before access is authorized.

03.14.06C5-COS-01argued against and upheld
Technical safeguards

System monitoring detects attacks and indicators of attack in inbound and outbound traffic.

03.13.01C5-COS-02argued against and upheld
Security requirements for connections in the Cloud Service Provider's network

External connections only through managed interfaces with defined boundary requirements.

03.14.06C5-COS-03argued against and upheld
Monitoring of connections in the Cloud Service Provider's network

Monitoring devices deployed strategically to observe traffic across the network.

03.13.06C5-COS-04argued against and upheld
Cross-network access

Network traffic denied by default so cross-network access is granted by exception.

Claims that did not hold

Nothing proposed for this pair was rejected in review. That is unusual and worth knowing rather than hiding: it means the candidate set was small and every candidate held.
