Automates evidence collection, control tracking, and audit reporting across SOC 2, ISO 27001, NIST 800-53, GDPR, and 12+ other frameworks in one platform.

Openlane is a compliance automation platform built for teams tired of stitching together spreadsheets, disconnected tools, and manual evidence collection. It centralizes controls, evidence, and frameworks into one place, then automates the repetitive work that typically consumes security and engineering time before an audit.
The core problem it targets is fragmentation. Most compliance programs involve too many tools that don't talk to each other, manual evidence gathering that repeats every audit cycle, and legacy platforms that weren't built for fast-moving teams. Openlane pulls that together.
What it handles:
Native integrations include AWS, GCP Security Command Center, GitHub, Google Workspace, Cloudflare, and Slack. Data syncs automatically and stays current without manual imports.
Compared to closed alternatives like Vanta or Secureframe, Openlane is fully open source with no gatekeeping on how you model your compliance environment. You're not locked into a vendor's interpretation of a framework or forced into a rigid workflow.
It's a practical fit for security teams at growing companies that need to hit compliance milestones without hiring a dedicated compliance staff or paying for a black-box SaaS tool that obscures what's actually happening under the hood.

AI-driven compliance platform that automates evidence collection, policy generation, and continuous monitoring across 580+ integrations for SOC 2, ISO 27001, HIPAA, and GDPR.

Comp AI is a compliance automation platform built for companies that need to get audit-ready without hiring a dedicated compliance team. It targets startups closing their first enterprise deals as much as mid-market teams scaling across multiple frameworks. The core idea: replace manual screenshots, spreadsheet tracking, and generic policy templates with AI agents that do the work continuously.
The platform covers SOC 2 Type I and II, ISO 27001, HIPAA, GDPR, and FedRAMP. During onboarding, AI learns your stack, processes, and risk tolerance, then generates policies specific to your business. No two customers get the same boilerplate.
Key capabilities:
One meaningful differentiator from tools like Vanta or Secureframe: the entire platform, including every agent and integration, is fully open source. You can audit the code on GitHub rather than trusting a vendor's claims.
Support runs through a 1:1 Slack channel with in-house compliance experts who respond in under three minutes. No ticketing system.
