The Third-Party Vendor Breach & Assessment

Your Systems Weren't Breached. Your Vendor's Were. The Result Is the Same.

Modeled on major supply-chain compromises, this assessment evaluates the vendor relationships that could expose your organization indirectly.

CORE OBJECTIVE

Some of the most damaging breaches started with a trusted vendor.

Not with the organisation that was affected. The Third-Party Vendor Breach and Assessment reviews your vendor ecosystem for the risk patterns that could turn a partner's weakness into your incident.

WHAT THE ASSESSMENT DELIVERS

Four things you will have at the end.

Vendor risk inventory

A map of the vendors, suppliers and software providers that touch your data or systems.

Vendor security posture review

An assessment of each critical vendor's risk from available information and questionnaire responses.

Staff awareness training

Training for the staff who deal with vendors, so a spoofed or compromised supplier message is caught.

Incident response coordination plan

Who does what, and who calls whom, when a vendor tells you they have been breached.

THE VISIBILITY GAP

Strong internal security can still be breached through a vendor.

Most organisations have little visibility into their vendor ecosystem. The assessment closes that gap.

WITHOUT AN ASSESSMENT

A blind spot

  • No complete list of vendors with access.
  • Vendor risk assumed, not reviewed.
  • No plan for a vendor-side breach.
WITH ONE

A mapped ecosystem

  • An inventory of who can reach what.
  • A rated view of critical vendors.
  • Staff and a response plan ready.

HOW IT RUNS

From a vendor list to a response plan.

This is not a penetration test. The assessment evaluates posture and risk from available information and questionnaire responses. Testing a vendor's systems would need the vendor's separate authorisation.

Map the ecosystem

List the vendors and what each can reach.

Review the posture

Rate the risk each critical vendor carries.

Prepare your people

Brief the staff who handle vendor requests.

Plan the response

Agree how you will coordinate if a vendor is breached.

IDEAL FOR

Two situations we see most.

You were asked to prove it

A larger partner has asked you to demonstrate your supply-chain security.

You have never mapped it

Nobody has listed your vendor dependencies and what each one can reach.

Frequently asked questions

Does this include testing of our vendors' actual systems?

No. The assessment evaluates posture and risk from available information and questionnaire responses. It is not a penetration test, which vendors would need to authorise separately.

Who should be involved?

Usually procurement, IT security and the owners of the vendor relationships. We agree the group when we scope the assessment.

The staff training in this assessment runs on the ProtectYourData platform. See how the training works.
