Shasta: Open-Source Compliance Automation Platform

Shasta is an open-source alternative to expensive compliance tools like Vanta and Secureframe, offering automated security checks, compliance frameworks, and remediation across AWS/Azure. It targets companies seeking to reduce the $10K-$80K annual spend on compliance management by providing accessible, auditor-grade documentation and security scanning.

SOC 2 and ISO 27001 demand has accelerated sharply as enterprise procurement teams now routinely gate vendor contracts on compliance certifications, pushing even early-stage startups to pursue audits far sooner than they used to. Vanta is the obvious incumbent here, having raised over $100M and largely defined the category, which means the positioning has to be "self-hosted, no recurring license tax" rather than feature parity. The $3k–$15k/mo revenue band is realistic only if the model leans on paid support, managed hosting, or a cloud-tier add-on — pure open-source with no commercial layer produces nothing, and the summary doesn't clarify which path is intended. The biggest risk is that compliance buyers are unusually risk-averse about the tooling itself: if an auditor questions whether the evidence collection pipeline is trustworthy, a scrappy open-source install loses to Vanta on credibility alone regardless of price.
