Case Study - Client Identity Withheld
Closing a compliance gap before it became a breach.
A regional financial services firm discovered a vendor access gap during our onboarding review. Details are anonymized at the client's request; the outcome is real.
The Problem
A third-party vendor credential had never been reviewed.
The firm had no dedicated security staff and no formal vendor access review process. A third-party vendor's credential, granted years earlier, still held standing access to internal systems long after the relationship's original scope had ended - a common gap that goes unnoticed until it is exploited.
What We Did
-
Rapid environment assessment
Within 48 hours we mapped the firm's critical systems, vendor access points, and existing log coverage to find where visibility was missing.
-
SIEM monitoring stood up
We deployed active log monitoring across endpoints and core infrastructure, tuned to the firm's specific vendor stack rather than generic rules.
-
Same-day containment
When a suspicious lateral-movement attempt was flagged, our team isolated the affected segment and closed the exposed vendor credential the same day.
-
Post-incident hardening
We rebuilt the firm's vendor access policy and access review cadence so the same gap could not be exploited twice.
