Supply Chain Security

Your supply chain isn't just open source

Security Testing Agent enforces your component policy, hardens your pipeline,
and proves what you deploy is what you scanned.

Why Teams Switch

SCA and SBOM are not enough

SBOM Enforcement

SBOMs were meant to be used

Every SCA tool generates SBOMs; none help you use them.

SBOM enforcement and response

Enforce SBOM policy and instantly surface impacted artifacts when a zero-day drops.

Pipeline Security

Pipelines are vulnerable too

SolarWinds wasn't a code vulnerability; it was a compromised build environment.

Secure the pipeline

Audit CI/CD pipeline risks and detect anomalous runner behavior.

Artifact Governance

You don't deploy code

Security tools scan code, but artifacts are what run in production.

Prove artifact provenance

Generate signed attestations linking every artifact to the code and pipeline that built it.

Software Bill of Materials

Supply Chain Security: enforce and respond

Every SCA tool can generate SBOMs. Most end up just sitting in a drawer. Security Testing Agent puts them to work protecting your supply chain.

Continuous SBOM generation. Automatically generate and update SBOMs on every build, capturing direct and transitive dependencies across all your repos.

SBOM policy. Enforce which components and licenses are approved, and automatically block any build that violates your supply chain policy.

Zero-Day Agent. Monitors threat feeds, flags every pipeline and artifact exposed to a new CVE, and opens a PR with the fix, so you just review and approve.

CI/CD Security

Harden your pipelines

Your pipeline runs your build, deploys your code, and holds your secrets. Harness locks it down.

CI/CD compliance. Audit pipelines against OWASP Top 10 CI/CD and CIS benchmarks.

Build environment protection. Detect anomalous CI runner behavior: network calls, privilege escalation, and more.

Risky pipeline actions. Flag unpinned, unverified, and over-permissioned GitHub Actions.

Artifact Integrity

Trust what you ship

Code gets scanned. Artifacts get deployed. Security Testing Agent proves that the artifacts you deploy came from the code you scanned.

Artifact attestations. Generate signed records linking every artifact to the source code and pipeline that built it.

Tamper detection. Detect when artifacts are modified between build and deploy.

Deployment gate. Block artifacts from production based on provenance, SBOM contents, or any OPA policy.

Shared Responsibility

Supply chain connects Dev, Sec, and Ops

Stay ahead of supply chain attacks

Protect your build environment from the inside out.

Flag risky pipeline actions and enforce SBOM policy before risks reach production.

Zero-Day Agent flags every affected service the moment a new CVE drops, and opens a PR with the fix.

FAQ

Frequently asked questions

Software Supply Chain Security protects the entire software development and delivery pipeline from code creation through production deployment. It encompasses multiple security layers including software composition analysis (SCA), secrets detection, container security, and Software Bill of Materials (SBOM) generation. Given modern applications' reliance on hundreds of third-party dependencies and build tools, this has become critical for preventing attacks like the SolarWinds breach and Log4Shell vulnerability that exploit trust relationships in the development ecosystem.

Major threats include compromised dependencies, malicious package injections, stolen credentials through inadequate secrets detection, and vulnerable container images. High-profile attacks like Codecov, SolarWinds, and npm package compromises demonstrate how attackers exploit trust relationships in the software supply chain. Additional risks encompass unsigned artifacts, absence of Software Bill of Materials for vulnerability tracking, and insufficient SLSA compliance.

SCA strengthens supply chain security by identifying vulnerabilities, licensing risks, and outdated components in software dependencies. SCA tools continuously monitor open source and third-party libraries against vulnerability databases, alerting teams to risks before exploitation. Modern SCA solutions automatically generate Software Bill of Materials, support secrets detection in dependencies, and integrate with container security scanning for comprehensive coverage across development and deployment environments.

These are complementary practices. While Software Bill of Materials provides an inventory of components, SLSA establishes verifiable provenance proving where and how software was built. SLSA Level 2 and above require build process documentation that complements SBOM data, creating comprehensive attestation. Organizations pursuing SLSA compliance typically generate signed SBOMs with provenance metadata, integrate container security verification, implement secrets detection, and maintain audit trails.

Secrets detection identifies exposed credentials, API keys, passwords, and tokens accidentally committed to code repositories or embedded in container images. Leaked secrets represent critical vulnerabilities, enabling attackers to compromise systems, access sensitive data, or inject malicious code. Modern secrets detection tools scan code repositories, container images, and build artifacts in real-time, preventing credential exposure before reaching production.

An SBOM is a comprehensive inventory listing all components, libraries, and dependencies within a software application. It provides transparency into your supply chain security posture by documenting component versions, licenses, and origin information. Regulatory frameworks increasingly mandate SBOM generation, making it essential for compliance. Organizations use SBOMs to rapidly identify exposure when new vulnerabilities are disclosed in open source components.

SLSA (Supply Chain Levels for Software Artifacts) is a security framework developed by Google and the OpenSSF that defines standards for securing the software supply chain. It provides four progressive maturity levels, from basic version control to comprehensive build integrity verification. SLSA compliance enhances supply chain security by establishing trust through cryptographic attestation and helping organizations prevent tampering and verify software provenance.

Container security is fundamental because containers package not only application code but entire dependency chains including base images, libraries, and system packages. Container security scanning examines images for vulnerabilities, malware, misconfigurations, and exposed secrets. Since vulnerable container base images affect all downstream applications, container security with SBOM generation provides visibility into your complete supply chain.

Generating accurate SBOMs requires automated tooling integrated into your CI/CD pipeline that analyzes code, dependencies, and container images. Leading SCA solutions create SBOMs in standardized formats like SPDX or CycloneDX. Maintaining accuracy demands continuous updates as dependencies change, integrating secrets detection, and enriching SBOM data with vulnerability information. SLSA-compliant build processes with cryptographic signing ensure SBOM integrity throughout the supply chain.

Implementation requires a multi-layered approach combining SCA for dependency analysis, secrets detection to prevent credential leaks, container security for image validation, and SBOM generation for transparency. Start by integrating SCA tools into your CI/CD pipeline, implement automated secrets detection across repositories, and generate Software Bill of Materials for all releases. Progress toward SLSA compliance through secure build processes, cryptographic signing, and provenance attestation, with regular container security scanning.
