Why it matters
- Shadow APIs may be exposed without security review.
- Zombie APIs often remain active after teams, products or integrations move on.
- Attackers look for forgotten paths because defenders monitor them less.
Shadow & Zombie APIs
Find APIs that are undocumented, forgotten, low-traffic, deprecated or outside governance.

Capability architecture
Shadow & Zombie APIs: context, validation and evidence.
This capability contributes to the same platform outcome: understanding realistic attacker exposure and proving what matters.
ThreatCanary approach
- Compare discovery, gateways, specs, logs and ownership sources to find gaps.
- Track traffic, last-seen and lifecycle stage to identify low/no-traffic APIs.
- Route suspected shadow or zombie APIs for owner review, testing or decommissioning.
What it validates or reveals
- Undocumented APIs.
- Low/no-traffic APIs.
- Deprecated, forgotten or ownerless endpoints.
Evidence and outputs
- A clear explanation of the exposure, affected assets and likely attack path.
- Reproducible evidence suitable for analysts, developers and risk owners.
- Prioritisation based on exploitability, business impact, sensitive data and chainability.
- Owner, remediation and workflow context that can move into Jira, Slack, SIEM or reporting.
