Certificate-Based Identity at Deploy Time
Every AI agent that touches your production infrastructure deserves a cryptographic identity — not a shared secret, not a static API key that lives in plaintext in configuration files. Arkion issues certificate-based identities to each agent at deployment time, embedding identity directly into the application's mTLS context. This eliminates the fundamental security gap where multiple agents share credentials, making lateral movement detection impossible and privilege isolation a fiction.
Each certificate is uniquely scoped to a specific agent instance, tied to its deployment manifest, and bound to cryptographic attestations from your infrastructure layer. When an agent starts, it receives a short-lived certificate that proves its identity through verifiable cryptographic material — not administrative fiat.
Full Lifecycle Management
AI agents operate through predictable state transitions. Arkion enforces a complete lifecycle model that reflects the real operational reality of non-human identities:
Provisioned
Agent infrastructure declared, certificate generation initiated, deployment manifest validated. The agent exists in your system but has not yet run. Risk is low; the identity is quarantined until first execution.
Active
Agent is running, certificate is valid, mTLS policies are enforced. This is the normal operational state. Real-time monitoring tracks certificate validity, usage patterns, and access permissions. Any anomaly in behavior triggers automated risk scoring and policy escalation.
Expiring
Certificate is within rotation window (configurable, default 30 days before expiry). Arkion initiates automated rotation workflows, issuing replacement certificates without downtime. Both old and new certificates are valid during the overlap window, allowing graceful transitions across distributed agent replicas.
Rotated
Old certificate has been replaced. Arkion tracks the rotation event, validates that new certificate is in use, and archives the old credential. Complete audit trail is maintained for compliance investigations.
Archived
Certificate is no longer active. Agent has been decommissioned, or its identity has been replaced. The archived credential remains queryable in audit logs but is not accepted for new mTLS connections.
Orphaned Agent Detection
Infrastructure evolves faster than documentation. Agents get deployed, forgotten, and left running in production for years. These orphaned agents become invisible to access controls, forgotten in backups, and unmonitored by security tooling. Arkion's passive infrastructure scanning continuously maps deployed agents against declared infrastructure, automatically flagging identities that exist in your systems but have no known owner, no documented purpose, and no active escalation path.
When an orphaned agent is detected, Arkion immediately creates an incident with escalation to infrastructure teams. Risk is scored based on certificate validity period, last observed activity, and network connectivity patterns. Long-dormant agents with valid certificates are treated as potential compromises.
Ownership Mapping and Accountability
Identity without ownership is unmanageable. Every agent in your system must have an assigned owner — a team, on-call rotation, or service owner who is responsible for its lifecycle, rotation schedule, and eventual decommissioning. Arkion enforces ownership as a first-class property of every non-human identity.
Ownership is not a static field. It integrates with your existing team directory, links to on-call escalation paths, and connects to incident management systems. When an agent's certificate enters the expiring state, Arkion automatically notifies the owning team through their preferred channels. If the owner team has been reorganized or disbanded, Arkion escalates to infrastructure leadership.
Policy-Enforced Mutual TLS
mTLS is only as strong as the policies that govern which identities can communicate. Arkion enforces granular mTLS policies at the platform level, ensuring that agent-to-service and agent-to-agent communication is restricted by certificate identity, not by network topology or role assumptions.
Policies are defined declaratively and validated at connection time. An agent trying to communicate with a service outside its allowed peer set is immediately denied, logged, and escalated as a policy violation. This creates a cryptographic enforcement layer that cannot be bypassed by misconfigured network ACLs or forgotten firewall rules.
Real-Time Risk Scoring at State Transitions
Identity state transitions carry risk. An agent moving from Active to Expiring, or from Archived back into use, indicates operational changes that may reflect security events. Arkion scores risk in real time as agents transition states, integrating signals from certificate validity, ownership status, last activity timestamp, and behavioral anomalies.
Risk scores feed into your existing incident management and SIEM platforms. High-risk transitions trigger automated investigations, policy holds, or manual reviews depending on your governance framework. Every state transition is immutable in the audit log, creating an unbreakable record of agent lifecycle events for compliance and forensic analysis.
