Vectara

Product: Vectara describes itself as an enterprise AI agent platform for governed, grounded, auditable agents.
What it does: The platform supports building agents that search company data, call external APIs, take actions, and retain context across conversation turns.
Retrieval: Vectara combines agentic document extraction, neural and lexical search, knowledge reranking, and customized generation.
Governance: Vectara says generated agent answers and actions include a factual consistency score and advanced tool validation.
Monitoring: Guardian Agents provide real-time RAG grounding, hallucination scoring, hallucination correction, and observability.
Integrations: Documented pipeline sources include S3, Google Drive, SharePoint, Box, Web, Confluence, and SCIM, while messaging connectors include Slack, Google Chat, and Zoom Contact Center.
API: Vectara provides REST APIs at api.vectara.io/v2 and authenticates requests with API keys or OAuth 2.0.
Security: Vectara says it does not train its models on customer data and is SOC-2 Type II and HIPAA certified.
Enterprise deployment: Vectara is offered as SaaS, within a customer's VPC, or on premises.
Support: Enterprise-tier accounts can receive written uptime and support response-time SLA guarantees through Vectara's online ticketing system.
Notable access limitation: Vectara's documentation says source-system permissions do not automatically carry over when records are indexed into a corpus; customers can replicate access metadata and apply query filters.
Who it serves: Vectara says enterprises use its platform to build AI agents for mission-critical applications.
