Case study — Third-party & vendor risk
Your vendors are part of your attack surface.
Exploit Shield monitors the domains and identifiers tied to your vendors and partners, not just your own, so exposure that starts with them doesn't stay invisible to you.

The case study
One vendor. Twenty-three institutions exposed.
Incident · Financial Services
Gateway to Mass Exposure
Exploit Shield flagged a .properties file containing core banking credentials. In the same directory were 23 nearly identical configuration files, each named for a different financial institution, all with hard-coded credentials tied to core banking systems like Symitar and Fiserv DNA, alongside API keys connecting to Visa and Mastercard payment processors. The repository had been public from May 2022 to February 2025. None of the 23 credit unions detected it. Visa and Mastercard did not detect it. Bug bounty programs did not report it. The vendor was unaware.
"Holy s**, that’s all of our code. That’s not supposed to be public."
Vendor CTO, reached by phone after emails went unanswered. Repository taken down within the hour.
Every one of those 23 institutions had a security program. Several had recently completed penetration tests. None of them detected the exposure, because it did not exist on their infrastructure and had never appeared on a dark web forum. By every conventional measure, they were covered.
None of them owned the repository. All 23 carried the risk anyway. That is the nature of vendor exposure: it does not respect the boundary between your environment and someone else’s.

One shared repository. Twenty-three separate victims.
Each line is a nearly identical config file in the same directory, hard-coded with a different institution's core banking credentials. One exposure, twenty-three separate blast radii.
How Exploit Shield helps
Coverage that extends past your own boundary.
Vendor domains, monitored continuously
Onboarding includes the vendor domains and identifiers that touch your environment, not just your own, so exposure that starts with a partner still reaches you.
Live across the platforms vendors actually use
Continuous monitoring of GitHub, GitLab, and Docker Hub, plus other public developer platforms where vendor code and credentials most often escape.
Attribution, not just a match
Every finding is scoped: source type, leak vector, and exposure scope, so you know which vendor, which system, and what it actually touches.
Delivered into your existing workflow
Findings are structured and delivered into Jira, Splunk, or OpenCTI, so vendor risk becomes a ticket your team can act on, not another report to read.
What we're hearing
Due diligence before the systems ever connect
In an early conversation, a company that had just acquired a data provider described a familiar worry: migrating the acquired company's data and services into their production environment without knowing what vulnerabilities or exposed credentials might come with it. A tool like Exploit Shield, run against the acquired company's footprint before integration begins, gives that answer before anything gets connected, not after.
