Based on Gartner® research, 92% of IT leaders are prioritizing two or more assistants, and organizations were using three on average. This report gives teams practical insights for evaluating enterprise AI assistants across six key criteria, from security and governance to capabilities, integrations, and cost.

What buyers should keep in mind
Assistants need to work across your entire stack
Buyers need to evaluate assistants across different models, clouds, deployment needs, and geographic requirements, and – critically – how well they work across existing tools without increasing vendor lock-in. Glean gives teams more flexibility across systems, rather than locking them into a single suite.
AI sprawl requires governance
As organizations adopt multiple assistants, governance gets harder. Gartner highlights monitoring, compliance, security integrations, and agent management as key areas to evaluate. Glean brings more visibility, control, and consistency to enterprise AI usage.
Useful assistants depend on trusted knowledge
Gartner’s definition of an enterprise AI assistant starts with search, connectors, tools, and extensibility. Glean connects employees to the right knowledge, context, and actions across the systems they already use.
Work AI that works.
