In a nutshell
- 🗺️ Build visibility fast: maintain a living risk register, rigorous data mapping, and clear RACI ownership, backed by frameworks like NCSC CAF, ISO 27001, and product SBOMs.
- 🔐 Prioritise regulator‑ready controls: universal MFA (phishing‑resistant for admins), pragmatic zero trust, robust EDR, centralised logging/SIEM, rapid patching with SLAs, and tested, immutable backups.
- 📁 Prove it with evidence: quarterly audit packs covering training, IR drills, supplier assurance, and pen‑tests; automate via GRC and CI/CD attestations; report to the board in risk, money, and time.
- 🔗 Tame supply chain and data flows: tier vendors, mandate a security addendum, request SBOM and build integrity proofs, monitor external attack surface; govern transfers with the UK International Data Transfer Agreement and data minimisation.
- 🚀 Act now with momentum: run a discovery sprint, tighten accountability, track MFA coverage, patch velocity, and recovery outcomes to turn regulatory pressure into measurable resilience and advantage.
The UK’s regulatory landscape is changing fast, and the digital security rules slated for 2026 bring sharper expectations, heavier documentation, and tighter timelines. For large enterprises and lean start-ups alike, the path is navigable with the right map. Treat compliance as a capability, not a chore. That mindset pays. New rules are converging around demonstrable risk management, auditable controls, and resilient supply chains. The practical question is simple: what should you do next week, not next year? Below, I set out pragmatic, high‑impact moves that align with guidance from the NCSC, the ICO, and sector regulators. Start now. Small actions compound. Delay, by contrast, compounds risk.
Map Your Risk, Data and Accountability Lines
Begin with a living risk register that ties threats to assets, controls, and owners. No guesswork. Catalogue critical services, crown‑jewel data sets, identities, and third‑party dependencies. You cannot comply with what you cannot see. Build a clear data mapping model: where personal data, telemetry, and intellectual property flow, which jurisdictions they cross, and who can access them. Include shadow IT and rogue SaaS; they’re often the breach vector. Short sprints help. Run a two‑week discovery burst using network scans, SaaS audits, and identity inventories, then reconcile results with business process maps.
Assign named accountability. Not vague committees. Use RACI across legal, security, engineering, and operations, and make sure a senior executive is visibly on the hook for security outcomes and reporting. The NCSC’s Cyber Assessment Framework offers a practical backbone; map your controls to it, ISO 27001, and Cyber Essentials Plus to demonstrate alignment. For software products, maintain an up‑to‑date SBOM and component risk profile. When regulators ask who owns a risk, a person’s name should appear—never a team logo. This clarity shrinks remediation time and strengthens board oversight.
Upgrade Technical Controls That Regulators Expect
Focus on controls with outsized risk reduction and clear auditability. Start with universal MFA, including phishing‑resistant methods for admins. Encrypt data in transit and at rest with modern ciphers and managed keys. Turn on comprehensive logging, centralise in a SIEM, and retain logs for a policy‑backed period. Default passwords are dead. Enforce unique credentials and device attestation for all remote access. Patch rapidly: score vulnerabilities by exploitability and exposure, not just CVSS, and define service‑level targets for critical fixes. Measure them. Misses should trigger escalation.
Adopt “zero trust” pragmatically: segment networks, limit east‑west traffic, and verify identity and device health before granting access. Deploy EDR, email threat protection, and web filtering that includes sandboxing. Backups must be immutable, routinely tested, and isolated; define RTO and RPO per service and prove you can hit them. For cloud estates, write down your shared‑responsibility model and tag all resources by owner, sensitivity, and environment. Link every control to a policy, every policy to a test, every test to evidence. Tools without proof look like theatre; controls with evidence look like compliance.
Prove Compliance With Evidence, Not Promises
Regulators will ask for evidence: policies, records, and outcomes. Prepare an audit pack you can refresh quarterly. Include training completion rates, incident response drill reports, supplier assurance files, and penetration test summaries with remediation. If it isn’t written down, auditors will act as if it never happened. Time‑box breach playbooks and make the notification pathway explicit: legal, comms, executive, regulator, customers. Clock‑watch your tabletop exercises and capture lessons learned. Automate where possible—ticketing systems, GRC tools, and CI/CD attestations reduce manual effort and errors.
| Obligation | Typical Owner | Expected Timing | Evidence Examples |
|---|---|---|---|
| Security risk assessment | CISO / Risk Lead | Quarterly refresh | Risk register, heatmaps, board minutes |
| Breach readiness and notification | Legal + IR Manager | Tight reporting windows | Runbooks, drill logs, decision matrix |
| Supplier due diligence | Procurement / Security | Onboarding + annual | Security addendum, SOC 2/ISO reports |
| Technical control testing | Security Engineering | Monthly/quarterly | Patch SLAs, MFA coverage, SIEM alerts |
Close the loop with board reporting that ties risk to money and time: exposure reduced, incidents contained, fines avoided. Use trend lines, not anecdotes. Evidence turns intent into credibility.
Manage Supply Chain Risk and Cross-Border Data
Your perimeter is your supply chain. Start by tiering vendors: critical, important, standard. For the top tiers, require a security addendum covering incident notification, vulnerability remediation, SBOM availability, encryption, and logging. Demand named contacts and escalation paths. Test them—request quarterly attestations and sample evidence. Provide secure channels for log sharing and forensics if incidents occur. Your security is only as strong as your least secure vendor. For software suppliers, ask about build integrity, signing, and dependency scanning; keep proofs on file. Where possible, monitor external attack surface entries—expired certs, exposed ports, leaked credentials tied to suppliers.
Cross‑border data transfers need deliberate governance. Document lawful bases, use the UK’s International Data Transfer Agreement or relevant EU SCCs where appropriate, and complete transfer risk assessments. Minimise data: keep only what you need, and anonymise when feasible. In cloud, write a data locality policy and enforce it with tagging and guardrails. Clarify shared responsibility with each provider and back it with service credits tied to security obligations. When data moves, your duty follows it. Build dashboards that show where data lives, who accessed it, and when it will be deleted.
The 2026 rulebook rewards organisations that can explain their risks, show their controls, and prove their outcomes. That’s the play: sharpen visibility, invest in measurable controls, and capture evidence as you work. Start with a discovery sprint, elevate accountability, and lock in supplier discipline. Build momentum with small wins people can see—patch speeds, MFA coverage, recovery tests. Compliance then becomes the by‑product of good security. As your teams plan the next quarter, which action will you take first to convert regulatory pressure into resilience and advantage?
