You have already done more of it than you think
You hold SOC 2. Now a customer wants ISO 27001. Most of that work is already sitting in evidence you collected last year, and the expensive part is finding out which parts. A coverage crosswalk tells you exactly which controls you already satisfy, which are genuine gaps, and the reasoning behind every claim so you can check it rather than take it on trust.
Pairs ready now
These have been reviewed and signed off. Buy one and the report is emailed to you immediately.
Any other pair
The graph holds 723 frameworks. Any pair can be built to order at the same price, delivered in five business days. If a pair is not in the list above it means the mappings have not been through review yet, and we will not send you a coverage number nobody has read.
- Every evidenced control, with its reasoning
- Every gap, with what it requires
- Stated limitations, not a confident number
How the mappings are made
Grounded in the source
Both frameworks are read from the issued standard held in our source corpus, not from a summary. Correcting one wrong control title in ISO 27001 changed a coverage figure by more than sixty points.
Argued against, then kept
Every candidate mapping goes through a second pass whose job is to refute it. On the first released pair, sixteen of fifty candidates were removed. What survives is what you get.
Read by a person
Refutation is a machine check and does not replace a reader. A pair is released only after review and sign-off, and the report carries the reviewer and the stated limitation.
What this is not
A crosswalk narrows the work. It does not replace an audit, and your assessor may take a different view on individual controls. Mappings between frameworks are judgements, not text printed in either standard, which is why every claim in the report shows its reasoning.
On the first released pair, two independent review passes each removed eight mappings and they overlapped on none. A third reader would probably still find something. That is in the report too, because you verify claims for a living and a stated limitation is worth more to you than a confident number.
Building an agent? The crosswalk is an MCP tool so an agent can find a pair and buy it without a human in the loop.
