ChatGPT Enterprise

Pros

• The enterprise governance set goes well beyond the Business plan, including SCIM, custom RBAC, customer-managed encryption keys on AWS, GCP, or Azure, and a compliance logs API.
• Data residency across multiple regions and HIPAA BAA eligibility make the plan usable in regulated industries.
• One seat bundles chat, deep research, image generation, voice, the ChatGPT Work agent, and Codex, so teams don't need separate AI tools for each task.
• Admins can set monthly per-user credit limits, overage caps, and alerts to govern agent and Codex spending.
• Connectors for Microsoft 365, Google Drive, Slack, and GitHub let company knowledge search answer questions from internal data.

Cons

• There is no public pricing. Per-seat figures come only from third-party estimates, and contracts are negotiated case by case.
• Usage-based charges for Work and Codex, with multipliers for long context, fast mode, and regional processing, make total cost hard to predict.
• The reported 150-seat minimum and annual commitment exclude smaller teams.
• Compliance logs for Work keep prompts for only 30 days and are not a full audit trail of tool calls, so a separate SIEM export is needed for longer retention.
• PeerSpot reviewers report context limits on very long documents and want finer per-team control over tone and response constraints.

Glean

Pros

• Glean lists more than 275 connected apps, so employees can search Slack, Drive, Jira, Salesforce and other tools from one place.
• Search results follow each source system's access controls, which lowers the risk of exposing data to the wrong people.
• AI answers include citations that link back to the source documents, so users can check them.
• Developers get Client and Indexing APIs, a Web SDK, agent toolkits and an MCP server for building on Glean.
• Its compliance certifications include SOC 2 Type II, ISO 27001, ISO 42001 and HIPAA.

Cons

• Glean publishes no prices; third-party reports put seats at about 50 dollars or more per user per month with minimums of roughly 100 seats.
• There is no free trial, and some reports describe proofs of concept as paid.
• Setup, permission configuration and relevance tuning take significant work from IT teams.
• Reviewers report renewal increases of about 3 to 12 percent a year and possible extra fees for premium support.
• Some users report answers that do not fully match the source data, and say the ranking is hard to customize.
