Diligio vs Eramba (open-source GRC)
The self-hostable open-source workhorse, compared with an agent-assisted SaaS built on your questionnaire knowledge base.
Eramba is the veteran open-source GRC platform: a real, usable Community edition at $0, a low-cost Enterprise edition, and full self-hosting for teams with strict sovereignty needs. It covers the classic GRC surface, risk, policies, incidents, awareness and exceptions, with the trade-off that you operate it and drive it manually. Diligio Compliance is the opposite shape: a managed SaaS where an AI agent proposes evidence and statuses, a human certifies, and the programme shares one knowledge base with your security questionnaires. If self-hosting or a $0 budget is the requirement, Eramba is the honest pick.
At a glance
Competitor details are publicly reported as of June 2026. Neither vendor publishes an official rate card, so pricing is hedged and dated.
Where Eramba is strong
- A genuinely free, usable Community edition, not a crippled trial, maintained by an active open-source community.
- Full self-hosting: for strict data-sovereignty or air-gapped requirements, running it yourself is the whole point.
- Mature coverage of the classic GRC surface: risk registers, policy management, incidents, awareness campaigns, and exception workflows.
- A flat, low fee for the Enterprise edition with no per-seat pricing.
Where Diligio Compliance is different
Agent-assisted versus hand-driven
Eramba gives you the structure, and your team does the work: controls, evidence, and reviews are maintained by hand. In Diligio Compliance, an AI agent you control proposes evidence and control statuses across a framework over MCP or REST, and a human certifies before anything is attested. The difference compounds with every review cycle.
Managed SaaS versus running your own GRC server
Self-hosting Eramba means owning upgrades, backups, and uptime for one more internal system. Diligio Compliance is a managed product on EU infrastructure. If your policy requires self-hosting, Eramba wins that requirement outright; Diligio Compliance is SaaS only today.
One knowledge base for questionnaires and compliance
Eramba does not answer your security questionnaires. Diligio Compliance shares one knowledge base with Diligio Respond, so the same approved answers drive your posture, your Trust Center, and your questionnaire responses.
Where Eramba is still ahead, honestly
On price at the bottom end (free is free), on self-hosting, and on years of hardening in classic GRC workflows. If those are your constraints, use Eramba. Diligio Compliance is the better fit when you want automation, an agent with a human-certify gate, and a maintained product without the ops burden.
Who should choose which
Choose Eramba if
you must self-host for sovereignty reasons, your budget is zero, or you have the in-house time to run a hand-driven GRC programme on a proven open-source platform.
Choose Diligio Compliance if
you want an audit-ready posture kept current with agent-assisted evidence and a human-certify gate, on a managed EU SaaS, sharing one knowledge base with your questionnaire answering.
