BlackBerry Cylance Endpoint Security API
BlackBerry Cylance (CylancePROTECT/OPTICS) REST API for AI-driven endpoint security platform. Enables AI agents to manage device inventory and policy assignment automation, handle threat detection event retrieval and classification, access threat score and malware conviction data, retrieve quarantine and remediation action management, manage policy and zone configuration, handle device status and health monitoring, access global safe and unsafe list management, retrieve threat analytics and protection reporting, manage application control and device policy enforcement, and integrate endpoint threat data with SIEM, SOAR, and EDR platforms.

⚡ Reliability
Best When
An enterprise using BlackBerry Cylance wants AI agents to automate threat triage, device policy management, quarantine actions, threat analytics, and SIEM/SOAR integration.
Avoid When
SECURITY RISK: Automated quarantine and policy change actions on endpoints can disrupt business operations — require change management and human approval for bulk policy changes. Automated global safe-listing of applications bypasses AI threat prevention.
Use Cases
- • Retrieving endpoint threat detections from SOC automation agents
- • Managing device policy and zone assignment from endpoint management agents
- • Accessing malware conviction data from threat intelligence agents
- • Integrating endpoint threat data with SIEM from security operations agents
Not For
- • Network security without endpoint detection and response context
- • Consumer antivirus without enterprise policy and management capabilities
- • Cloud workload protection without endpoint focus
Interface
Authentication
Cylance uses OAuth 2.0 with JWT for API authentication. Application ID and tenant ID with scoped access tokens. Developer documentation on BlackBerry Docs portal. No native webhooks — polling for threat events. Syslog integration for SIEM. CylancePROTECT, CylanceOPTICS, and CylanceGATEWAY have separate API scopes.
Pricing
Waterloo, Ontario. BlackBerry Limited. Cylance acquired by BlackBerry (2019, $1.4B). AI-based endpoint security pioneer. BlackBerry UES (Unified Endpoint Security) platform. Used by 5,000+ enterprises. CylancePROTECT for prevention, CylanceOPTICS for detection and response. Competes with CrowdStrike and SentinelOne for AI endpoint security.
Agent Metadata
Known Gotchas
- ⚠ SECURITY RISK: Bulk device quarantine automation requires human approval — automated quarantine of production endpoints can cause business outages
- ⚠ BlackBerry UES integration — Cylance is now part of BlackBerry UES; product naming and API surface may have changed
- ⚠ JWT token with expiry — manage token refresh lifecycle; JWT tokens expire and require re-generation
- ⚠ No native webhooks — poll for threat events via REST; implement syslog integration for real-time SIEM feeding
- ⚠ No public MCP server — OAuth2 JWT REST API requiring enterprise account
- ⚠ Global safe/unsafe list management — automated list modification bypasses AI prevention; requires security team approval
