AI Tool Usage Tracking: Why CASB & DLP Miss Shadow AI

If your ISO 27001 certificate covers all of your health and care data processing, the NHS Data Security and Protection Toolkit does two useful things with it. It marks the applicable evidence items as complete on its own, and it shrinks the scope of any independent audit to whatever your certification doesn’t already cover. A certified vendor who does the mapping properly walks into a DSPT submission with most of the technical and organizational evidence already written, already audited, and already versioned. What ISO 27001 won’t do is get you out of the DSPT. It says nothing about the NHS-specific information governance items, clinical safety, the national data opt-out, or Caldicott principles. Vendors who assume “certified means done” usually discover this in the last two weeks of June. This piece is for the founder, CTO, or ops lead at a UK health-tech company who owns compliance without being a compliance person. It covers what each framework asks for, which Annex A controls line up with which DSPT requirements, which evidence you can reuse as-is, which needs reframing around patient data, and a five-step workflow for turning an existing ISMS into a DSPT submission. One more thing on timing: NHS England published DSPT version 9 for the 2026/27 cycle on 4 September 2026, and the submission deadline is 30 June 2027. So this exercise belongs in your calendar now, not next spring. Understanding the Two Frameworks at a Glance​ What ISO 27001:2022 Covers ISO/IEC 27001:2022 is the international standard for an Information Security Management System (ISMS). It comes in two halves. Clauses 4 to 10 define the management system itself: context, leadership, risk assessment and treatment, resourcing, operation, performance evaluation, and continual improvement. Annex A lists 93 reference controls across four themes (organizational, people, physical, technological). Your Statement of Applicability (SoA) records which of those controls you apply, which you exclude, and why. An accredited certification body issues the certificate after a two-stage audit, then you keep it through annual surveillance audits and a three-year recertification cycle. The certificate covers a defined scope, and that scope statement is the first thing a DSPT assessor reads. What the NHS DSPT Requires in 2026/27 The Data Security and Protection Toolkit (DSPT) is NHS England’s annual online self-assessment for every organization that touches NHS patient data or systems. It’s a contractual requirement under the NHS Standard Contract. Your published status (“Standards Met”, “Standards Exceeded”, “Approaching Standards”, “Standards Not Met”) is publicly searchable, so procurement teams and prospective NHS customers do look it up. The Toolkit isn’t one assessment. NHS England tailors it by organization category, and your category decides which assertions you answer and whether you need an independent audit. Version 9 came out on 4 September 2026. The Category 1 view is aligned to CAF version 4.0, and the whole thing closes on 30 June 2027. Insider Note: Most health-tech SaaS vendors are Category 3, not Category 2. To be an IT Supplier you need all three things at once: digital goods or services to the NHS, 50 or more staff, and £10 million or more in turnover. Picking “IT Supplier” because you sell NHS-facing software, without hitting the size thresholds, lands you in a heavier evidence set and a mandatory audit you may not need. Check the category before you check anything else. Key Structural Differences Between ISO 27001 and DSPT Four differences matter when you’re trying to reuse evidence. What they’re about. ISO 27001 is an information security standard. The DSPT is an information governance standard that includes security. A good chunk of it deals with lawful basis, transparency, data subject rights, records management, and the SIRO and Caldicott Guardian roles. None of that is in Annex A. How you’re assured. ISO 27001 gets certified once and surveilled once a year by an accredited body. The DSPT starts from a blank submission every year, and Category 1 and 2 organizations get independently assessed every year too. How granular they are. Annex A controls read as objectives (“access rights shall be provisioned, reviewed, modified and removed”). DSPT evidence items read as things to upload (“a list of all systems that hold personal data, with the date of last review”). So the mapping runs many-to-one in both directions. Where they’re heading. Since 2024/25 NHS England has been moving the Toolkit onto the NCSC Cyber Assessment Framework (CAF). CAF is outcome-based: assessors score you Achieved, Partially Achieved, or Not Achieved against an NHS England profile, rather than accepting a policy upload as proof. Category 1 organizations are already there. Category 2 and 3 are still on assertions and evidence, but NHS England has said CAF alignment will reach more organization types over time. The Business Case for Reusing ISO 27001 Evidence in DSPT How Much of DSPT Can Realistically Be Satisfied by ISO 27001 Controls For a Category 2 or 3 vendor with a full-scope ISO 27001 certificate, expect 60 to 75 percent of the mandatory evidence items to come from ISMS artifacts, either automatically (where the Toolkit auto-completes them) or with some light reframing. The rest is NHS-specific governance and information governance content that ISO 27001 doesn’t touch. The NHS’s own guidance treats reuse as a scope question. The DSPT help pages say an ISO 27001 certification must cover all health and care data processing to receive the full exemption, and that a certificate scoped only to an IT department is good evidence for many of the IT questions but not all of them. If your certificate says “the SaaS platform hosted in AWS eu-west-2” and NHS data also passes through your support desk tooling, your analytics sandbox, and a contractor’s laptop, the auto-completion won’t apply. Your assessor will want to know how those flows are controlled. Time and Cost Savings for Health-Tech Vendors There’s no fee to submit the DSPT. The cost is internal time, plus, if you’re Category 2, the independent audit and the annual penetration test the mandatory assertions expect. Building a first DSPT submission from nothing usually takes
