"A credential leak in what looks like a side project can silently expose an entire enterprise group. Linkup is what helps us with attribution – in real time, inside our workflow."  Alexis Begnez, Engineering Manager, GitGuardian

GitGuardian is a leading secrets and Non-Human Identity security platform, protecting organizations from credential exposure across their development ecosystem. The platform monitors more than 610,000 enterprise repositories and detects hundreds of thousands of potential secret leaks each year.

Detecting a leaked credential is only the beginning. The harder question is: how far does the exposure reach? To answer it faster and more reliably, GitGuardian integrated Linkup's search API into their incident response workflow – bringing real-time corporate intelligence directly to the moment teams need it most.

The Challenge

A leaked credential belonging to what appears to be an isolated project may grant access to infrastructure shared across a much larger corporate group. Without knowing whether an affected entity is a subsidiary, division, or affiliate of a parent organization, security teams risk underestimating the scope of an incident. 

Manually researching corporate relationships during an active incident is slow, inconsistent, and incompatible with the narrow time window between detection and remediation.

Pain points before Linkup:

• No reliable way to determine parent or subsidiary relationships in real time

• Manual research slowed down incident response workflows

• Risk of under-scoping breaches affecting larger corporate groups

Why They Chose Linkup

GitGuardian needed a search solution that could resolve corporate relationships instantly within their incident response workflow, without requiring manual investigation.

Key reasons:

• Linkup returns a broad coverage across authoritative public sources (company sites, filings, press releases) out of all leading search providers

• Source-cited, auditable results suitable for high-stakes security decisions

• No infrastructure to maintain. Linkup handles search and scraping, so GitGuardian's team focuses on security, not data pipelines

• Real-time API delivery integrated directly into incident workflows

Results

With Linkup, corporate relationship research that previously required manual investigation is now resolved automatically at detection time. For each incident, teams get source-cited context on parent companies, subsidiaries, and ownership structures – without leaving their workflow.

• 1 hour saved per company analyzed on manual corporate research (for x,000 of companies to analyze weekly)

• Escalation decisions backed by verifiable, auditable sources

• Better corporate mapping that allows for better and faster incident attribution

For monitoring and security teams, Linkup ensures decisions are based on accurate, real-time context – enabling faster, more efficient remediations.
