*Own the models, data, and code behind your defense & intelligence AI on your own infrastructure — vs. a per-seat assistant running in Glean's cloud*

**On ibl.ai you own all the code and the data, run it model-agnostic across any LLM, and pay with no per-seat pricing — so you can deploy anywhere, from your own cloud to a fully air-gapped network.**

## What's the difference between Self-Hosted AI and Glean?

Defense & Intelligence organizations adopting AI face one hard constraint before any feature: controlled unclassified and classified material must stay protected under ITAR, CMMC, and classification controls. Where the AI runs — and who controls it — matters as much as what it does.

Glean is a managed assistant from Glean, billed at about $40 per user per month and running in Glean's cloud on Glean's hosted model selection. Its strength is strong enterprise search across connected SaaS applications with little setup, but it is tied to Glean's hosted index and models and your data is processed in the vendor's cloud.

Self-hosted AI runs on infrastructure you control — on-premise, in your private cloud, or fully air-gapped. You own the code, the data, and the models, run any LLM, and keep controlled unclassified and classified material inside your perimeter, integrated with GovCloud, SIPR-adjacent enclaves, PIV/CAC authentication, and existing mission systems. This comparison covers document triage, intelligence summarization, workforce training, and knowledge preservation for defense & intelligence — and when each option is the right call.

## Feature Comparison

### Capabilities

| Criteria | Self-Hosted AI | Glean |
|----------|--------------------|--------------------|
| Out-of-the-Box Productivity | Strong agent capability once deployed; you configure the workflows your teams need. | Polished assistance from day one with strong enterprise search across connected SaaS applications. |
| Defense & Intelligence System Integration | Deep integration with GovCloud, SIPR-adjacent enclaves, PIV/CAC authentication, and existing mission systems via APIs and MCP, built around your data. | Connects to common tools, but integration with sector systems is limited. |
| Custom Agents & Workflows | Build and own production agents for document triage, intelligence summarization, workforce training, and knowledge preservation. | A few prebuilt agents; customization is bounded by the platform. |
| Any-LLM & Model Control | Run any open or commercial model, route by cost/latency/capability, and switch anytime. | Runs on Glean's hosted model selection; tied to Glean's hosted index and models. |

### Ownership & Data Control

| Criteria | Self-Hosted AI | Glean |
|----------|--------------------|--------------------|
| Self-Hosting / On-Prem / Air-Gapped | Run on your servers, private cloud, or fully air-gapped with zero external calls. | Runs in Glean's cloud; cannot be self-hosted or air-gapped. |
| Data Stays in Your Perimeter | controlled unclassified and classified material never leaves your environment; every interaction is logged for audit. | Vendor controls help, but data is processed in the provider's cloud. |
| Model Choice | Any LLM — open-source or commercial — under your control. | Locked to Glean's hosted model selection. |
| Source Code & Platform Ownership | Own the full platform code; no lock-in to a vendor's roadmap. | You rent access; the platform and roadmap belong to the vendor. |

### Cost & Compliance

| Criteria | Self-Hosted AI | Glean |
|----------|--------------------|--------------------|
| Cost at Scale | Flat, usage-based cost on owned compute — no per-seat fees. | about $40 per user per month; cost rises with every seat. |
| Compliance & Audit Fit | Data stays in your perimeter, supporting ITAR, CMMC, and classification controls with full audit logging. | Vendor compliance coverage under shared-responsibility cloud terms. |
| Time-to-Value | Requires infrastructure and setup, or a partner to deploy it for you. | Turn it on for your users with minimal setup. |
| Support & Maintenance | Self-managed, or fully supported with forward-deployed engineers. | Fully managed by Glean with enterprise support. |

## Detailed Analysis

### Defense & Intelligence Data Sovereignty vs Cloud Convenience

**Self-Hosted AI:** Self-hosted AI keeps controlled unclassified and classified material inside your perimeter and can run fully air-gapped — the strongest posture for ITAR, CMMC, and classification controls.

**Glean:** Glean adds capable assistance quickly, but processes data in Glean's cloud under shared-responsibility terms.

**Verdict:** For defense & intelligence workloads bound by ITAR, CMMC, and classification controls, owning the stack is the safer default; Glean fits lower-sensitivity productivity.

### Per-Seat Cost vs Flat Ownership

**Self-Hosted AI:** Self-hosting replaces per-seat licensing with flat cost on compute you own, so broad rollouts don't scale with headcount.

**Glean:** Glean is about $40 per user per month, predictable per user but growing with every license.

**Verdict:** For organization-wide deployment, owned infrastructure is often far cheaper at scale.

### Model Freedom vs a Single Vendor

**Self-Hosted AI:** A model-agnostic platform runs any model — including the vendor's own — and switches as the frontier moves.

**Glean:** Glean is tied to Glean's hosted index and models.

**Verdict:** If avoiding model lock-in matters, the owned, model-agnostic platform wins.

## FAQ

**Q: Is there a self-hosted, ITAR/CMMC-ready alternative to Glean for defense & intelligence?**

Yes. A self-hosted, model-agnostic platform runs on infrastructure you control, keeping controlled unclassified and classified material in your perimeter under ITAR, CMMC, and classification controls — while delivering AI agents for document triage, intelligence summarization, workforce training, and knowledge preservation without per-seat fees.

**Q: Can it run air-gapped, unlike Glean?**

Yes. It can run on-premise or fully air-gapped with local models and zero external calls. Glean is a cloud service in Glean's cloud and cannot be self-hosted or air-gapped.

**Q: Where does controlled unclassified and classified material go with Glean vs self-hosting?**

Glean processes data in Glean's cloud under shared-responsibility terms. With a self-hosted platform, controlled unclassified and classified material stays entirely within your environment and every interaction is logged for audit.

**Q: Is self-hosted AI cheaper than Glean at scale?**

Usually, for large rollouts. Glean is about $40 per user per month, so cost grows with every seat. Self-hosting replaces that with flat, usage-based cost on compute you own.

**Q: Can I still use Glean's hosted model selection?**

Yes. A model-agnostic platform can route to Glean's hosted model selection alongside open and other commercial models — and switch anytime — rather than being tied to Glean's hosted index and models.

**Q: How does ibl.ai fit in?**

ibl.ai is a model-agnostic, self-hosted AI platform you own and run on your own servers — on-premise or air-gapped — for document triage, intelligence summarization, workforce training, and knowledge preservation, while supporting ITAR, CMMC, and classification controls by design.


## Where does ibl.ai fit alongside Self-Hosted AI and Glean?

**ibl.ai is the agentic AI platform where you own all the code and the data. You self-host the entire stack inside your own perimeter, run it model-agnostic across any LLM and switch anytime, and pay by usage with no per-seat pricing — so you can deploy anywhere: your cloud, on-premise, GovCloud, or fully air-gapped.**

ibl.ai is a self-hosted, model-agnostic AI Operating System you own and run on your own infrastructure — on-premise, in your private cloud, or fully air-gapped — so controlled unclassified and classified material stays in your perimeter under ITAR, CMMC, and classification controls.

Agentic OS orchestrates agents and workflows across any LLM for document triage, intelligence summarization, workforce training, and knowledge preservation, integrated with GovCloud, SIPR-adjacent enclaves, PIV/CAC authentication, and existing mission systems via APIs and MCP; Agentic LMS delivers training; Agentic Course generates materials. You own the code, data, and models — SOC 2, HIPAA, and FERPA compliant by design, with no per-seat fees.

- **You own all the code and the data.** Full source code under a perpetual license, running on your infrastructure. Not API access to someone else's platform — the stack itself is yours.
- **Model-agnostic.** Run any LLM — Claude, GPT, Gemini, Llama, Command, or your own fine-tune — and switch providers without rewriting the platform.
- **No per-seat pricing.** Usage-based billing against a budget cap you set. Cost tracks what your organization actually uses, not how many people you employ.
