Here’s the thing about IASME Cyber Essentials Plus that catches people out. It isn’t a harder standard. It’s the same five controls you’ve already been assessed on, except this time somebody checks they’re genuinely working rather than taking your word for it.
Where it gets expensive is the timing. You have three months from your last Cyber Essentials certificate to get the Plus audit done. Miss that and you’re back at the beginning, redoing Cyber Essentials before you can even book the test.
There’s a second one worth knowing about. If a sample of devices fails on security updates, the retest doesn’t just revisit those devices. It pulls a fresh random selection too, so patching only the machines that got tested won’t save you. Fail twice and the Cyber Essentials certificate goes with it.
The carousel runs through the sequence and the housekeeping worth doing before audit day.
