AWS Well-Architected Security Pillar covers 25.3% of PCI DSS 4.0
63 of the 249 controls in PCI DSS 4.0 are already satisfied by evidence you collected for AWS Well-Architected Security Pillar. 186 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.
This number is directional. It says how much of PCI DSS 4.0 your AWS Well-Architected Security Pillar 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.
129 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.
Network config held as version controlled code with drift detection evidences secured, synchronised configurations.
Restricting inbound flows to only those each component needs is the same tested control.
Same control restricts egress from workload components to only necessary flows.
Public, private and restricted subnet layering is the network security control between trusted and untrusted zones.
Layering places only internet facing components in public subnets, restricting inbound untrusted traffic.
Isolating data tiers from internet facing components is exactly this requirement.
Access Analyzer public access findings evidence that data stores are not reachable from untrusted networks.
CloudTrail across all accounts and regions plus service logs is audit logging enabled everywhere.
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.
