Core Features

Fleet Management

Manage the lifecycle of Synapse sensors across the fleet.

  • Sensor registration — register new sensors via REST API, issue authentication tokens
  • Health monitoring — heartbeat tracking with configurable stale thresholds (WS_HEARTBEAT_INTERVAL_MS)
  • Grouping — organize sensors by region, tenant, or custom labels
  • Metrics — per-sensor traffic volume, detection rates, latency
  • Config templates — create reusable configuration bundles and push to sensor groups
  • Command queue — send commands to sensors with delivery tracking and acknowledgment

Rule Authoring

Create, test, and distribute WAF rules.

  • Rule creation — author rules via REST API with regex patterns and risk scores
  • Rule strategies — deploy rules with immediate, canary, or scheduled strategies
  • Sync tracking — per-sensor sync state in rule_sync_state table
  • Rollback — remove or deactivate rules across the fleet

Intelligence Features

Advanced Threat Detection

ML-driven threat scoring and multi-signal correlation.

  • Signal scoring — combine multiple signal types into composite threat scores
  • Campaign detection — cross-tenant correlation using anonymized SHA-256 fingerprints
  • Escalation — automatic severity escalation when campaigns cross thresholds
  • Blocklist automation — auto-create blocklist entries for high-severity threats

Impossible Travel

Geographic anomaly detection for sessions and actors.

  • Location tracking — GeoIP-based session location analysis
  • Travel speed — detect physically impossible movements between requests
  • Signal creation — generates IMPOSSIBLE_TRAVEL signals from credential stuffing events with location metadata

Signal Array

Multi-signal aggregation and composite alerting.

  • Signal types — aggregate across WAF, DLP, bot, session, and behavioral signals
  • Composite scoring — combine individual signal risk scores into an overall threat assessment
  • Alerting rules — trigger alerts when composite scores exceed configurable thresholds

Security Features

DLP Protection

Data Loss Prevention at the edge.

  • Pattern matching — credit cards, SSN, IBAN, API keys, and custom regex patterns
  • Actions — mask, hash, block, or log detected PII
  • Edge enforcement — DLP scanning happens in Synapse before traffic reaches your backend

Operations Features

TestBed

Integrated security testing environment.

  • Scenario execution — run predefined attack scenarios against a sensor
  • Validation — verify detection rules work as expected before production deployment

War Room

Collaborative incident response.

  • Real-time collaboration — shared workspace for investigating active campaigns
  • Activity log — timestamped record of all investigation actions
  • Bot automation@horizon-bot auto-creates war rooms for high-severity campaigns

API Intelligence

Schema learning and violation detection.

  • Endpoint profiling — learn expected request/response schemas from live traffic
  • Anomaly detection — flag requests that deviate from learned schemas
  • Documentation — auto-generate API documentation from observed traffic patterns

Blue-Green Deployments

Zero-downtime sensor deployment.

  • Traffic shifting — gradually shift traffic between sensor versions
  • Health gating — automatic rollback if the new version reports unhealthy metrics

Shadow Mirroring

Safe rule testing against live traffic.

  • Mirror mode — copy live traffic to a shadow Synapse instance
  • Comparison — compare detection results between production and shadow rules
  • Zero risk — shadow results don't affect production traffic

Capacity Planning

Fleet sizing and resource forecasting.

  • Traffic analysis — historical traffic patterns and growth trends
  • Resource projection — estimate CPU, memory, and bandwidth needs for fleet expansion

Drift Management

Detect and resolve configuration drift across the fleet.

  • Drift detection — compare actual sensor config against templates
  • Remediation — push corrected configuration to drifted sensors

Remote Shell

Secure remote access to sensor instances.

  • Authenticated access — API key-scoped remote shell sessions
  • Audit logging — all remote shell commands logged for compliance

Firmware Updates

Sensor firmware lifecycle management.

  • Version management — track firmware versions across the fleet
  • Staged rollout — deploy firmware updates using canary strategies

Tunnel Monitoring

Monitor WebSocket tunnel connections between sensors and the hub.

  • Connection status — real-time view of tunnel health
  • Latency tracking — round-trip latency measurements
  • Reconnection — automatic reconnection with configurable backoff
