Marketplace provenance is the origin trail for a plugin or extension, showing where it was installed from and how it entered the environment. It helps security teams judge trust, assess supply chain risk, and distinguish official sources from community or repository-based installs that may behave differently over time.
Expanded Definition
Marketplace provenance is the verifiable origin trail for a plugin, extension, or add-on, including where it was obtained, how it was installed, and which distribution path brought it into the environment. In NHI and agentic AI contexts, provenance helps security teams distinguish an official marketplace release from a community package, sideloaded artifact, or repackaged dependency that may change behaviour after installation.
Definitions vary across vendors on how much provenance data is required. Some teams treat provenance as simple source attribution, while stronger governance models also record publisher identity, package hash, signing status, approval path, and update channel. That distinction matters because a trusted source can still deliver a risky artifact if the installation path bypassed review or if the package later inherited new permissions. NIST guidance on software integrity and access control, including NIST SP 800-53 Rev 5 Security and Privacy Controls, supports this broader view of trustworthy software intake.
For NHI security, provenance is not just a procurement detail. It is a control input for deciding whether a plugin should receive secrets, tool access, or execution authority. The most common misapplication is assuming that an item is trustworthy because it came from a familiar marketplace, which occurs when teams skip validation of the actual install source, publisher, and update lineage.
Examples and Use Cases
Implementing marketplace provenance rigorously often introduces review overhead, requiring organisations to weigh faster self-service deployment against tighter supply chain control.
- An AI coding assistant plugin is approved only if the team can trace the install back to the official marketplace listing and verify publisher identity.
- A service account extension is blocked because it was sideloaded from a community repository, even though a similarly named official version exists.
- A security team investigates an API key leak and finds the source in a marketplace plugin documented in the JetBrains Marketplace AI Plugin Campaign, where malicious plugins stole AI API keys.
- A build pipeline only allows marketplace packages that include signed release metadata and an auditable approval record before deployment.
- An organisation compares the install source of a browser extension against the controls in NIST SP 800-53 Rev 5 Security and Privacy Controls to confirm software provenance and integrity requirements.
Marketplace provenance also matters when the same plugin can be installed through multiple channels, because one path may include enterprise review while another permits direct user installation. NHIMG research on the Ultimate Guide to NHIs shows how often organisations expose NHIs to third parties, which makes source validation especially important for marketplace-delivered tooling.
Why It Matters in NHI Security
Marketplace provenance determines whether a plugin should be trusted with secrets, tokens, certificates, or privileged API calls. If provenance is weak, organisations may grant execution authority to code that arrived through an unreviewed channel, creating a direct path from software intake to NHI compromise. That risk is amplified in environments where plugins can read configuration, call external services, or manipulate credentials on behalf of an agent.
NHI Mgmt Group reports that 92% of organisations expose NHIs to third parties, raising concerns about supply chain security, and that statistic becomes more serious when third-party plugins are the delivery mechanism. Provenance helps answer the operational question of not only what the plugin is, but where it came from, who introduced it, and whether that path was governed. Without that trail, incident responders often cannot distinguish a legitimate marketplace install from a shadow installation that bypassed controls.
Marketplace provenance becomes operationally unavoidable after a secret leak, malicious plugin discovery, or unexplained agent behaviour forces teams to reconstruct how the software entered the environment.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
OWASP Non-Human Identity Top 10 and OWASP Agentic AI Top 10 address the attack and risk surface, while NIST CSF 2.0, NIST Zero Trust (SP 800-207) and NIST SP 800-63 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| OWASP Non-Human Identity Top 10 | NHI-01 | Focuses on risky NHI supply paths and third-party exposure. |
| OWASP Agentic AI Top 10 | AGENT-04 | Agent toolchains must be vetted to prevent untrusted extensions. |
| NIST CSF 2.0 | PR.DS-6 | Data integrity depends on trustworthy software sources and updates. |
| NIST Zero Trust (SP 800-207) | SA.PO-1 | Zero trust requires explicit trust decisions for software and tools. |
| NIST SP 800-63 | Identity assurance concepts inform trust in publishers and install actors. |
Record install source, publisher, and approval trail before granting plugin access to NHI secrets.
