Glean is a genuinely strong, permission-aware enterprise search platform used by fast-moving, SaaS-native companies. If your knowledge already lives in Slack, Google Workspace, and a handful of modern SaaS tools, it’s a serious option. But Glean is a US company running in the cloud (even at its most private, single-tenant), and its connector depth is strongest inside SaaS — if you also need on-premise or legacy sources covered, or infrastructure that’s provably outside US jurisdiction, the calculus changes. Here’s how they actually compare, category by category.
Mimirio
Glean
What it is
AI platform that searches, answers, and takes action across all your company’s data — SharePoint, Teams, file servers, and more — deployed entirely under your control.
Enterprise search and work AI assistant — indexes your company’s SaaS tools (Slack, Google Workspace, Confluence, Jira, Salesforce, GitHub, and more) and increasingly builds agents on top of that index.
Deployment model
On-premise, private cloud, or hybrid — deployed and scaled inside your own infrastructure, with no seat minimums and no hyperscaler dependency required.
Single-tenant, either Glean-hosted or deployed into your own AWS, Azure, or GCP account — real infrastructure isolation, but still cloud, not literally on-premise.
Data residency & sovereignty
Stays inside your infrastructure or an EU private cloud of your choosing — never leaves your control, never crosses a border you didn’t approve, and isn’t reachable by any foreign jurisdiction’s legal process.
Multi-region hosting (Americas, EMEA, APAC) gives real data-residency choice — but as a US company (Glean Technologies, Inc., Palo Alto), it’s still reachable under the US CLOUD Act regardless of region.
Customer data used for model training?
Never — and you don’t have to take our word for it. You control the model, the infrastructure, and the security, so it’s fully auditable, not just promised.
Never — Glean has zero-retention agreements with its model providers, so customer data is never stored or used for training.
AI models used
You choose the model that fits your security and compliance needs — on-prem, EU-hosted, or hybrid — and can switch it later without re-platforming. No vendor lock-in.
Model-agnostic — works with multiple LLM providers under zero-retention agreements rather than one fixed model.
Data source integrations
SharePoint, Teams, Outlook, Confluence, Jira, file servers, and more — connected and searchable out of the box, across every silo in your company, not just one vendor’s ecosystem or the SaaS tools you happen to already use.
Deep, well-built connectors across modern SaaS tools (Slack, Google Workspace, Salesforce, GitHub, and more) — excellent breadth inside SaaS, less focused on on-premise file servers or legacy systems.
Permission-awareness
Every search result and every agent action respects your existing access permissions — enforced at the source system, not re-implemented or approximated by us, so nothing is ever exposed that a user couldn’t already see.
Yes — enforced, source-system permissions in search and retrieval are one of Glean’s core, well-documented features.
Compliance & certifications
GDPR and EU AI Act compliant by design, not retrofitted — on-prem or EU-private-cloud deployment keeps you outside most cross-border transfer questions entirely, with no foreign parent company, no CLOUD Act exposure, and no legal framework still being challenged in court.
Publishes a strong security architecture (zero-retention agreements, enforced permissions, single-tenant isolation); as a US company it carries the same CLOUD Act exposure as other US vendors, and specific certifications aren’t as clearly itemized on their public site as Mimirio’s.
Governed agentic actions
Skills let Mimirio act on your behalf — draft a report, update a record, send a notification — with every action scoped to a specific permission, logged, and fully auditable after the fact, not just governed in principle.
Glean Agents can trigger from events, route tasks, and connect to external systems — real action-taking with governance and permissions built in, though public detail on per-action audit trails is thinner than what’s shown here for Mimirio.
Cost and Licence
Per seat, roughly €10–€50/month depending on volume, plus your deployment’s operational costs — one predictable quote for the whole deployment, not a stack of separate SKUs to reconcile. Exact pricing on request.
Enterprise-tiered, contact sales — no public self-serve pricing or published per-seat rate.
Best fit for
Orgs that need enterprise knowledge search and safe agentic automation without being tied to a US-hosted platform for infrastructure control.
Orgs already deep in modern SaaS tools (Slack, Google Workspace, Salesforce, etc.) that want best-in-class permission-aware search and are comfortable with a US-based vendor, even with private single-tenant hosting.
