Implement once. Map to everything.
Access control, change management, risk assessment, logging, incident response and vendor due diligence appear in almost every framework on this page. They are worded differently, evidenced differently and audited differently, but underneath they are the same controls doing the same job. Organisations that run a separate programme per framework end up building them three times, maintaining three sets of evidence, and discovering in year two that the three have quietly drifted apart.
So we start from the control set rather than the standard. One implementation, one risk register, one evidence trail, mapped outward to whichever frameworks you actually have to satisfy. Adding a second framework to an organisation that already has the controls operating is a mapping exercise and an audit, not another programme — which is why the order you take them in has a real effect on cost.
The other half is that evidence should be a by-product of controls operating, not a task somebody performs before an audit. SemperWise One™ maps controls to live signals across these frameworks, collects the evidence continuously, and flags a control the day it drifts rather than eleven months later. Our security testing feeds the same register, so a penetration test finding and a control failure are one object rather than two teams’ separate problems.
