About C1.ai

C1.ai gives agents policy-controlled access to models, tools, and credentials at runtime. C1 Agents complete multi-step jobs across connected systems, with human approval for sensitive changes. C1.ai connects to SaaS, cloud infra providers, on-prem systems, and MCP servers.[2]

On the governance side, C1.ai turns HR and directory events into day-one account and access changes across supported systems. C1.ai provisions users the access they need based on conditions and policy. C1.ai applies policy-based provisioning and routing to any connected system. C1.ai covers user access reviews and separation-of-duties (SoD) conflict detection. C1.ai gives people and agents self-service access to approved applications and AI tools, with policy applied before fulfillment.[1][2][3]

For self-service, C1.ai makes approved apps, MCP servers, AI tools, roles, and permissions discoverable from one catalog. People and agents can request access from the web, Slack, Microsoft Teams, MCP, API, or CLI. C1.ai auto-approves routine access and routes sensitive requests using identity, role, resource, and risk context. C1.ai expires just-in-time access automatically so temporary permissions do not become standing access.[4]

For cloud infrastructure, C1.ai provides engineers and agents with precisely scoped cloud access. C1.ai reads cloud providers' resource trees, preserving the parent-child relationships each platform uses natively. C1.ai resolves inherited permissions in real time. C1.ai provisions, adjusts, and revokes access automatically as roles change, teams shift, or agents are redeployed.

Every action in the console is available via API, and C1.ai operates as an MCP server. C1.ai governs human, service, workload, and AI agent identities from one control plane. C1.ai logs every action with full context: subject, actor, delegation chain, purpose, resource, policy, and outcome. C1.ai supports policies as Terraform, AI-written CEL and functions, and validation via API. Technical teams extend C1.ai with APIs, custom functions, CLI, webhooks, and an AI integration builder, and manage it with Terraform.[2][6]

C1.ai includes 300+ connectors, built on Baton, which is open source under Apache 2.0, that integrate IdPs, directories, SaaS apps, cloud infrastructure, and on-prem systems into one identity graph. The connectors can be hosted or self-hosted. The identity graph ingests identity, permission, and resource data from all of your systems. C1.ai visualizes access paths for users, non-human identities, applications, and resources. C1.ai addresses access risks such as orphaned accounts, inactive users, and high-risk users. C1.ai offers built-in remediation options such as downgrading access, offboarding accounts, and securing service accounts. C1.ai connects to non-cloud infrastructure, including LDAP, Postgres, and Microsoft SQL. C1.ai covers on-premises technology such as Active Directory and homegrown and back-office apps.[1][6][7]

IGS Energy started looking for a partner after an external auditor recommended an identity governance solution to streamline user access reviews.[1][2][8]
