What is Third Party Data Breaches?
Third‑party data breaches occur when one of your vendors leaks your customers’ data — support tools,
analytics tags, cloud storage, processors. You haven’t done anything “wrong,” but you’re left holding the bag: account
takeovers, credential stuffing, refund abuse, reputational damage.
Prepare before you need a press release: Reduce shared data, restrict access with segmentation, and monitor
vendors for evidence you can act on: security reports, pen‑test summaries, incident history. Retain egress logs,
and rotate secrets on a schedule. When a breach occurs, force resets, monitor for geovelocity spikes, and layer
in sensitive flows with identity verification for high‑risk users. Record the
impact clearly within your AML compliance and incident response processes.
Trust vendors, but verify — and verify often.
