Cyber Made Simple — week 19 2026-05-04

What happened this week

Cyber threats continue to remind us that no organisation operates in a bubble. This week's coverage highlighted how attacks on one business can ripple out and disrupt others nearby — whether that's a supplier, a partner, or a public service — making the case that cybersecurity is very much a shared responsibility rather than a solo effort.

What to do next

Take five minutes this week to check whether your key suppliers have any basic cybersecurity measures in place — even a quick look at their website for a security or privacy policy is a start. If a supplier you rely on were hit by ransomware tomorrow, it's worth knowing now whether your operations would grind to a halt alongside theirs.
