Achieve SLSA Level 2+ Across All Your Build Infrastructure
Probatus Suite is the cross-platform software supply chain security solution that brings attestation, verification, and visibility to your entire CI/CD ecosystem—regardless of where you build.

The Multi-Platform Build Challenge
Modern development teams don’t use just one build platform. You might have:
- GitHub Actions for your core applications
- GitLab CI for internal tools
- Jenkins for legacy systems
- CircleCI for mobile apps
- Cloud-native builds on AWS, GCP, or Azure
Each platform generates artifacts. Each needs security attestations. But managing compliance across all of them? That’s been nearly impossible—until now.
What is Probatus Suite?
Probatus Suite is a unified software supply chain security platform that automatically generates, signs, and verifies provenance metadata across all major build systems. Get comprehensive visibility and SLSA compliance without rebuilding your CI/CD infrastructure.

Why Software Supply Chain Security Matters
Software supply chain attacks increased by 742% in recent years. From SolarWinds to Log4Shell, the risks are real and growing.
Probatus Suite helps you:
- Prove artifact integrity to customers and auditors
- Meet regulatory requirements (EO 14028, NIST SSDF, EU Cyber Resilience Act)
- Prevent tampered dependencies from reaching production
- Detect and respond to supply chain threats faster
- Build customer trust with verifiable security claims
The problem? Most solutions only work with one platform or address one aspect of supply chain security. Probatus Suite provides comprehensive, cross-platform protection.

How It Works
1. Connect Your Build Platforms
Integrate Probatus Suite with your existing CI/CD systems using native plugins or our universal webhook adapter.
2. Automatic Attestation Generation
Probatus Attest captures build metadata automatically—no code changes needed. Every build gets a cryptographically signed provenance statement.
3. Centralized Verification & Visibility
All attestations flow to Probatus Suite. View, search, and verify artifacts across your entire organization from one platform.
4. Policy Enforcement
Set organization-wide security policies. Block non-compliant artifacts. Enforce SLSA levels per environment or team.
5. Continuous Monitoring
Probatus Insight monitors your supply chain for emerging threats, policy violations, and compliance drift.

Frequently Asked Questions
Do I need to change my existing CI/CD pipelines? No. Probatus Suite integrates as a plugin, extension, or webhook—your existing workflows remain unchanged.
What SLSA level does Probatus Suite provide? Probatus Suite provides SLSA Level 2 out of the box with configurable paths to Level 3 and 4 depending on your build platform capabilities.
Where are attestations stored? In cloud deployments, attestations are stored in tamper-evident storage with optional replication to your infrastructure. For self-hosted deployments, everything stays in your environment.
Can I use my own signing keys? Yes. Probatus Suite supports both keyless signing via Sigstore and bring-your-own-key (BYOK) models with HSM integration options.
Does Probatus Suite work with private/self-hosted runners? Absolutely. Probatus Suite supports cloud-hosted, self-hosted, and air-gapped environments.
How does this compare to other SLSA tools? Most SLSA tools are platform-specific (e.g., only for GitHub Actions) or require you to completely rebuild your CI/CD. Probatus Suite works across all platforms and integrates with your existing infrastructure.
What about SBOM generation? Current version focuses on SLSA attestation with SBOM support via integration with existing SBOM tools. Native SBOM generation is on our roadmap.
Can I try before buying? Yes! Our free tier gives you full access to core features with generous limits. No credit card required.
What kind of support do you offer? Community support for free tier, email/chat support for Professional, and dedicated support with SLAs for Enterprise customers.
