How do I assess the cyber security of a supplier?
Key takeaways
- Check the specific indicators below before assuming the worst — many suspected compromises are something else entirely.
- Preserve evidence before you change anything, because the first change can destroy the proof you need.
- Containment comes before recovery, and recovery comes before cleanup.
- Proof of ownership is required before we work on any account, device or system.
What the signs usually look like
These are the indicators we check for. The presence of one is a prompt to look closer, not a diagnosis.
- A critical supplier cannot name a security contact
- Their questionnaire responses are generic or very old
- They connect to your systems remotely with shared credentials
- A recent breach or outage you heard about second-hand
- No breach notification clause in your contract
What we actually do
We tier your suppliers by access and dependency, run structured due diligence on the critical ones, review the contract clauses that should exist, and put continuous external monitoring on their exposed infrastructure.
You get a written record of what was checked, what was found, and what was not found. That last part matters as much as the first two: it tells you which risks you can stop worrying about.
What you can do right now
- Write down what you have observed and when it started. Timestamps matter more than impressions.
- Do not delete the app, wipe the device, or change passwords in a panic — each of those can destroy evidence.
- If money is at risk, contact your bank first. Most payment fraud is recoverable within hours and not at all after days.
- Preserve the original: the message, the email, the file, the video. Work from a copy.
- If an account is locked, work back to the root account that everything else recovers through.
What this usually costs
Most of these assessments are a fixed-fee engagement with a stated band agreed before work starts, and a delivery date you can plan around. If the situation is urgent — a ransomware note on screen, a deepfake spreading right now, a payment that has just left — say so when you contact us and we will prioritise it accordingly.
