Vectra AI Network Detection & Response API
Vectra AI REST API for AI-driven network detection and response (NDR) platform. Enables AI agents to retrieve threat detection events and Attack Signal Intelligence data, handle host and account-level detection and scoring queries, access detection severity and urgency scoring from AI models, retrieve PCAP and network session metadata, manage detection status updates and triage workflows, handle SIEM integration for threat event streaming, access entity-level threat prioritization data, retrieve campaign and attacker behavior analysis, manage detection suppression and tuning data, and integrate Vectra threat intelligence with SOAR, SIEM, and XDR platforms.

AI NDR. SOC2, ISO27001, GDPR. API token. US/EU. Network threat detections and entity risk data.
⚡ Reliability
Best When
An enterprise using Vectra AI wants AI agents to automate threat event triage, detection status management, entity risk scoring, SIEM integration, and SOAR-driven incident response.
Avoid When
SECURITY RISK: Automated detection suppression must not silence high-severity detections without human review — suppression of active threats creates blind spots. Automated incident response triggered by Vectra AI signals requires confidence scoring and human escalation for critical detections.
Use Cases
- • Streaming network threat detections to SIEM from security operations agents
- • Triaging Vectra threat events from SOC automation agents
- • Accessing entity risk scores from threat prioritization agents
- • Integrating Vectra detections with SOAR from incident response agents
Not For
- • Endpoint detection without network behavior analysis context
- • Email security without network threat detection requirements
- • Log management and SIEM without NDR threat detection focus
Interface
Authentication
Vectra uses API token authentication. Account-level tokens from platform settings. REST API documentation via Vectra support portal. Webhooks for detection events. Vectra clients library on GitHub. SIEM integrations with Splunk, QRadar, and Microsoft Sentinel. Vectra Stream for continuous PCAP metadata.
Pricing
San Jose, California. Founded 2011. AI-driven NDR market leader. $350M raised. 1,000+ enterprises. Attack Signal Intelligence (ASI) differentiator. Hybrid NDR for cloud and on-premises. Microsoft Azure and M365 Copilot for Security integration. Competes with Darktrace and ExtraHop for NDR market.
Agent Metadata
Known Gotchas
- ⚠ SECURITY RISK: Automated detection suppression can hide active threats — require human review for suppression of high-severity detections
- ⚠ API token scope is full account — no granular scope controls; protect token carefully
- ⚠ Documentation behind support portal — requires Vectra customer account to access full API docs
- ⚠ No public MCP server — API key REST API via support portal
- ⚠ Detection pagination — large environments generate high detection volumes; implement robust pagination
- ⚠ Vectra Stream separate from REST API — PCAP metadata streaming uses separate Vectra Stream protocol
