Open Source GRC
GRC platforms earn their keep by collapsing the duplicate work of overlapping audits - one control mapped once and reused across SOC 2, ISO 27001, and internal policy - so the value is in the cross-framework mapping, not any single checklist. The open source options here let you maintain that control library, evidence, and framework mappings on your own infrastructure, keeping audit evidence and the relationships between controls in a system you can extend as new frameworks land.
