Open Source Oneleet Alternatives

Probo combines an open-source compliance automation platform with a managed service. Dedicated compliance officers run your program so your team doesn't have to. They handle risk and vendor assessments, gap analysis, policy documentation, evidence collection, and direct communication with auditors. You join the essential calls, and they prepare you for those too.

Supported frameworks include SOC 2 Type 1 and Type 2, ISO 27001, ISO 27701, ISO 42001, HIPAA, GDPR, FERPA, CCPA, CASA, and SOC 3. Once certified, the team keeps monitoring controls, refreshing evidence, and maintaining audit readiness in the background.

Evidence collection is automated through the platform. You can access documents, trigger workflows, and message your compliance officer directly in Slack. There's also a branded trust page you can share with customers or prospects to show your compliance status.

Being open source means no vendor lock-in. Backed by Y Combinator, Probo targets startups and smaller teams that need to reach certification quickly without building an internal compliance function — making it a focused alternative to tools like Vanta or Sprinto.

Openlane is an open-source compliance automation platform built for security and GRC teams that need to manage multiple frameworks without stitching together spreadsheets and disconnected tools. It covers SOC 2, ISO 27001, NIST 800-53, GDPR, and more than a dozen other frameworks from a single interface, connecting controls, evidence, and audit reporting in one place.

The core problem it addresses is manual compliance work. Evidence collection, control testing, and policy tracking traditionally consume significant time and often fall apart under audit pressure. Openlane automates evidence gathering, tracks control status continuously, and keeps everything audit-ready without a last-minute scramble.

Risk monitoring is built in. Teams can identify gaps early, track open tasks, and watch compliance status change in real time rather than discovering problems when an auditor does. Roles and approvals can be assigned across teams, so leadership, security staff, and external auditors all work from the same current data.

Native integrations pull data from tools teams already use: AWS, GCP Security Command Center, GitHub, Google Workspace, Cloudflare, and Slack. Synced data stays current automatically, so there's no manual export-import cycle to maintain.

Being open source is a meaningful distinction here. Proprietary GRC platforms often obscure how compliance is being tracked and charge heavily for access to basic functionality. Openlane gives teams full visibility into the platform itself, with no gatekeeping on controls or evidence workflows. Tools like Probo and Comp AI take similar open approaches to compliance, though each covers different framework priorities.

According to the project, teams using Openlane report spending 82% less time on evidence collection and saving 80+ hours in the process of achieving compliance. Those numbers reflect what happens when repetitive manual tasks get replaced with automated tracking across a centralized program.

Comp AI transforms compliance from a manual, time-consuming process into an automated workflow that scales with your business. Whether you're a startup closing your first enterprise deals or an enterprise managing complex regulatory requirements, this platform handles SOC 2, ISO 27001, HIPAA, GDPR, and FedRAMP compliance through intelligent automation.

The platform's core strength lies in continuous evidence collection from over 500 integrations. Rather than relying on manual screenshots and spreadsheets that become outdated, AI agents automatically pull evidence from your cloud infrastructure, vendors, and systems 24/7. This means your compliance posture always reflects current reality, not last quarter's state.

Key capabilities include:

• AI-generated policies tailored to your specific stack, processes, and risk tolerance—not generic templates
• Automated evidence collection from AWS, GCP, GitHub, and 500+ other tools
• Device agents that monitor encryption, firewall settings, and security configurations on every employee machine continuously
• Penetration testing agents that probe your code and APIs for vulnerabilities
• Live trust centers that display only verified, current compliance status to prospects
• Expert support with 1:1 Slack access to compliance specialists responding in under 3 minutes

The platform is fully open source and auditable, so you verify every agent and integration rather than trusting a black box. Customers report getting audit-ready in days instead of weeks or months, with 600+ companies already using Comp AI across startup, mid-market, and enterprise stages. The combination of automation, expert support, and transparency makes compliance feel less like a burden and more like a competitive advantage.
