A string of recent incidents — from medical-device maker Stryker to NHS software and equipment suppliers — all share one theme: the organisation that got hurt wasn't the one that got hacked. Their supplier was. The NCSC's supply-chain security guidance is a practical place to start getting a grip on this risk.
The problem in plain terms
Modern businesses run on a web of suppliers: software platforms, IT providers, payroll, logistics, connected apps. Attackers have noticed that compromising one well-connected supplier can give them access to hundreds of that supplier's customers at once. So they increasingly target the supplier, not you directly — and you inherit the consequences.
What the NCSC recommends (in everyday language)
The NCSC's collection sets out how to improve supply-chain security for organisations that rely on suppliers to deliver products and services. The core ideas:
- Understand what you're trusting. Map your suppliers and identify which ones are critical to your operations or hold your data.
- Set clear expectations. Build security requirements into contracts and onboarding — certifications, MFA, breach notification.
- Manage access tightly. Give suppliers only the access and data they need, and review it regularly.
- Plan for failure. Assume a key supplier could be disrupted, and have a fallback.
- Keep it ongoing. Supplier risk isn't a one-off tick-box; review it as relationships change.
Where Foresight fits
Most SMEs have never mapped their supplier risk, let alone built it into how they buy and operate. That's exactly the kind of practical groundwork we help with — turning guidance like this into a short, sensible checklist for your business.
