What is Probo?
Founded in 2024 and headquartered in San Francisco, Probo combines a dedicated compliance officer with an open-source compliance platform. The YC-backed company says it serves 100+ customers across 20+ countries and supports 10+ frameworks.
Probo is a compliance-as-a-service offering built on an open-source platform. A dedicated compliance officer reviews the customer’s environment, risk and vendor assessments, defines the appropriate program, prepares policies and documentation, coordinates the auditor, and keeps the program maintained after certification. Evidence collection, updates, approvals, controls, risks, audits, and trust-center materials are managed in the platform, with Slack access for day-to-day work.
The product covers compliance operations rather than just a task checklist: automated evidence collection, policy and control management, risk assessment, vendor reviews, audit preparation and coordination, continuous monitoring, branded trust pages, and access to an open-source or self-hosted deployment. Supported coverage includes SOC 2 Types 1 and 2, SOC 3, ISO 27001, ISO 27701, ISO 42001, GDPR, HIPAA, CCPA, FERPA, CASA, NIS2, and DORA. Its main limitation is that the managed model is service-led and less suitable for large enterprises needing extensive global customization or a pure software-only implementation.
Probo is aimed at startups and growing technology companies facing enterprise security reviews, especially teams without an internal compliance specialist. Publicly listed customers and references include Ahrefs, Typebot, Tinfoil Security, Vybe, Lucis, Bluejay, Morphik, Verso, Whaly, and Trace For Good. The self-hosted open-source core is free, while the managed full-service offering starts at $10,000 per year; enterprise deployments are custom quoted, and an auditor’s fees may be separate depending on the engagement.
Key features
Dedicated compliance officer
A named compliance expert runs the program, advises the team, manages documentation, and coordinates the audit.
Automated evidence collection
The platform collects, updates, and routes evidence and approvals so teams are notified mainly when action is required.
Risk and vendor assessments
Probo performs risk analysis and vendor reviews as part of setup and ongoing compliance maintenance.
Audit preparation
The service prepares policies and evidence, selects or helps select an auditor, and manages auditor communications.
Continuous monitoring
After certification, Probo refreshes evidence, updates controls, and maintains assessments for ongoing readiness.
Trust center
Customers can publish a secure branded trust page for sharing compliance evidence with prospects and customers.
Open-source deployment
The core platform can be deployed and self-hosted, preserving data ownership and reducing vendor lock-in.
Probo pricing
The free tier is the self-hosted open-source platform. Probo’s published comparison lists Full Service from $10,000 per year, including a dedicated compliance officer, gap assessment, risk analysis, vendor reviews, custom policies, audit preparation and representation, and 12 months of maintenance; Enterprise is custom. A Capterra listing gives a separate benchmark of $8,000 per feature per year, so buyers should confirm the current managed quote and whether auditor fees are included.
| Plan | Price | What's included |
|---|---|---|
| Self-hosted open source | Free | Framework tracking, compliance workflows, automated evidence collection, community support |
| Full Service | From $10,000/yr | Dedicated compliance officer, gap assessment, risk analysis, vendor reviews, custom policies, audit preparation and representation, 12 months of maintenance |
| Enterprise | Custom | Bring-your-own-cloud deployment, forward-deployed compliance engineering, custom frameworks, enterprise support |
Free trial: The open-source platform is free to self-host; Probo says buyers can test the product before purchasing, but does not publish a fixed managed-service trial duration.

Frequently asked questions
How much does Probo cost?
+
The open-source self-hosted core is free. Probo’s published comparison lists managed Full Service from $10,000 per year and Enterprise as custom; Capterra lists $8,000 per feature per year, so the scope and current quote should be confirmed.
How long does Probo take to make a company audit-ready?
+
Probo’s published comparison says most companies reach audit readiness in 6–8 weeks with full-service support. Its Ahrefs case study reports 10 weeks to audit-ready and 13 weeks to ISO 27001 certification.
How does Probo compare with Vanta?
+
Probo assigns a compliance officer who does the work, while Vanta is primarily an automation platform that expects the customer to manage the program. Probo also offers a free self-hosted open-source core; the tradeoff is a more service-dependent model and a smaller enterprise footprint.
What integrations does Probo support?
+
The compliance service works in Slack. Its MCP documentation supports Claude, OpenAI, Cursor, Windsurf, Zed and VS Code for connecting AI tools to compliance workflows.
Who is Probo for?
+
It is designed for startups and growing technology companies that need SOC 2, ISO 27001, privacy, healthcare, or AI compliance without building an internal compliance function. The strongest fit is a team that wants an expert to execute the program rather than merely provide software.
Is Probo secure and accurate enough for an audit?
+
Probo’s compliance page lists ISO 27001 (2022) for Probo Inc. Its process combines automated evidence collection with human review, policy work, risk assessment, and auditor coordination; the independent auditor still provides the certification or attestation.
