Software Attestation Frameworks Compared: SLSA, in-toto, and Sigstore
Software attestation proves that your artifacts were built the way you claim. Here is a practical comparison of SLSA, in-toto, and Sigstore for securing your build pipeline.
Third-Party SBOM Trust: Can You Verify a Vendor's Bill of...
A vendor's SBOM is a claim, not proof. Here's what actually verifies third-party software bills of materials — and why signatures alone aren't enough.
Software Supply Chain Security Maturity: Where Does Your Organization Stand?
Most organizations know they should care about software supply chain security, but few have a structured way to assess their maturity. A practical framework for evaluating and improving your posture.
SLSA v1.1 Build Track: What Approved Means for Adopters
SLSA v1.1 was approved in April 2025 with the Build track stabilized. We dig into the spec changes, what L2 and L3 verifiers must reject, and how producers should re-evaluate provenance.
Zero Trust Principles Applied to the Software Supply Chain
Zero trust is not just a network architecture concept. Applied to the software supply chain, it fundamentally changes how organizations verify code, dependencies, and build processes.
Provenance Attestation Consumer Workflow
Generating provenance is half the story. Consuming it correctly, at the right points in the pipeline, is where the security value actually materialises.
SLSA Build Provenance for Python Publish
Python packages on PyPI can carry SLSA provenance via PEP 740. Here is the publish workflow, the verification story, and the parts that still do not quite fit together.
How to Validate SLSA Provenance in CI
Generate and validate SLSA v1.0 provenance attestations in GitHub Actions using slsa-verifier, gate releases on builder identity, and prove build integrity.
SLSA Builder Requirements in Production
The SLSA specification sets explicit requirements for builders at each level. Here is what those requirements actually mean when you operate a builder in production.
in-toto Attestation Formats Reviewed
The in-toto attestation framework is the plumbing under SLSA, Sigstore, and most supply chain tooling. Here is a practical review of the v1 formats and their edges.
SLSA for Go Releases: A Practical Guide
Go's build model makes SLSA provenance more tractable than most ecosystems. Here is the practical guide for producing and verifying provenance on Go releases.
SLSA Level 3 in Practice: What It Takes
SLSA Build L3 is achievable in a week per repo if you use a hosted builder — and nearly impossible if you insist on rolling your own. Here is the practical path.
