Workflow
Your audit-ready path
Four steps IT and GRC teams use when preparing evidence for assessments.
Scope & framework
Choose SOC 2, ISO 27001, CIS, PCI, HIPAA, NIST, or GDPR scope. Define systems, owners, and audit timeline.
Map controls
Align organizational controls to framework requirements. Document owners, frequency, and evidence types.
Collect proof
Gather screenshots, logs, tickets, policies, and test results using templates and interactive checklists.
Present & improve
Package evidence for auditors, close gaps, and feed findings back into monitoring and hardening.

Other compliance frameworks
Jump between SOC 2, ISO, PCI, HIPAA, CIS, NIST, and GDPR hubs.
SOC 2
Learn how to implement, document, and present controls for access, change management, monitoring, backups, incident response, and endpoint protection — with evidence auditors expect.
ISO 27001
Build ISMS literacy: risk treatment, Annex A controls, policies, asset management, supplier security, and certification readiness for security and operations teams.
HIPAA
Security Rule safeguards, privacy workflows, risk analysis, access controls, audit logging, and breach readiness for healthcare IT and compliance teams.
CIS Controls
Turn CIS Controls and benchmarks into actionable hardening for Linux, cloud, and enterprise infrastructure — prioritized safeguards and implementation groups.
NIST CSF
