What This Workflow Does

This automation solves the critical challenge of ensuring security teams receive immediate notification of high-priority alerts from TheHive. Traditional email-based alerting often leads to delayed responses during security incidents, especially outside business hours. The workflow automatically converts TheHive alerts into SIGNL4 notifications, leveraging mobile push, SMS, and voice calls for guaranteed delivery.

By implementing this solution, security teams can reduce mean time to respond (MTTR) by up to 80% compared to manual processes. The integration maintains all critical alert context including severity levels, observables, and case references while adding SIGNL4's robust notification capabilities. This creates a closed-loop system where teams can acknowledge and act on alerts directly from their mobile devices.

How It Works

1. TheHive Alert Trigger

The workflow monitors TheHive's REST API for new alerts matching configured criteria. It supports filtering by alert severity, tags, or specific observables to prevent notification overload. The trigger captures the complete alert payload including case references, timestamps, and threat indicators.

2. Alert Processing

Critical alert fields are extracted and formatted for SIGNL4 compatibility. The workflow maps TheHive severity levels to appropriate SIGNL4 priority settings, ensuring high-severity alerts trigger immediate phone call notifications while lower-priority alerts use mobile push.

3. SIGNL4 Notification

The processed alert is sent to SIGNL4's API with all necessary context for responders. SIGNL4 handles delivery through configured channels (mobile app, SMS, voice) according to escalation policies. The workflow logs all notification attempts and responses for audit purposes.

Who This Is For

This solution benefits security operations centers (SOCs), IT security teams, and managed security service providers (MSSPs) using TheHive for incident management. It's particularly valuable for organizations that require 24/7 coverage or have distributed security teams needing mobile access to alerts.

Pro tip: Combine this workflow with SIGNL4's duty scheduling to ensure alerts always reach the currently on-call team members, even during weekends or holidays.

What You'll Need

  1. TheHive 5.x instance with API access
  2. SIGNL4 account with appropriate subscription tier
  3. n8n instance or compatible automation platform
  4. API credentials for both systems

Quick Setup Guide

  1. Import the workflow JSON into your n8n instance
  2. Configure TheHive API credentials in the trigger node
  3. Add your SIGNL4 team ID and API key to the action node
  4. Adjust alert filters and severity mappings as needed
  5. Test with sample alerts to verify notification delivery

Key Benefits

Faster incident response with mobile-first alerting that reaches responders anywhere, reducing mean time to acknowledge critical alerts by 60-90%.

Reduced alert fatigue through intelligent filtering that only forwards high-priority alerts to mobile devices while lower-priority items remain in TheHive.

Auditable notification trail that records exactly when alerts were sent and acknowledged, supporting compliance requirements.

Flexible escalation policies that automatically notify backup responders if primary contacts don't acknowledge alerts within defined timeframes.

Frequently Asked Questions

Common questions about security alert integration and automation

The integration ensures critical security alerts from TheHive reach the right team members immediately via SIGNL4's reliable notification system. This reduces response times during security incidents by eliminating manual alert forwarding.

Security teams can configure escalation policies and on-call schedules within SIGNL4 to ensure 24/7 coverage. The mobile-first approach means responders can acknowledge and act on alerts from anywhere, significantly improving incident response metrics.

  • 60-90% faster alert acknowledgment times
  • Configurable escalation paths for critical alerts
  • Mobile access to alert details without VPN requirements

The workflow automatically converts TheHive alerts into SIGNL4 notifications while preserving all critical details. It maps alert severity levels to appropriate notification channels based on configured business rules.

For example, critical alerts might trigger immediate phone calls while medium-severity alerts use push notifications. The system maintains complete context including case references, observables, and timestamps to help responders quickly assess the situation.

  • Automatic severity level mapping
  • Full alert context preservation
  • Configurable channel selection by priority

Prioritize forwarding high-severity alerts like brute force attacks, malware detections, and suspicious privilege escalations. These time-sensitive incidents benefit most from immediate mobile notification.

The workflow can filter alerts based on severity, tags, or specific observables before forwarding. This prevents alert fatigue while ensuring critical incidents receive appropriate attention. Consider your team's capacity and incident response SLAs when configuring filters.

  • Focus on alerts requiring immediate action
  • Filter by severity, tags, or observables
  • Balance responsiveness with notification volume

Yes, the workflow complements existing SIEM integrations by adding mobile-first alerting through SIGNL4. It processes alerts from TheHive regardless of their original source, creating a unified notification layer.

The solution works alongside other security tools without disruption. Many organizations use it to enhance their existing SIEM investments by adding reliable mobile notifications for critical alerts that would otherwise only appear in dashboards or email.

  • Enhances existing SIEM investments
  • Unified notification layer across tools
  • No conflict with other integrations

SIGNL4 provides enterprise-grade reliability with delivery confirmations and escalation fallbacks. The system automatically retries failed notifications and escalates to backup contacts if needed.

With support for multiple redundant channels (SMS, push, voice), SIGNL4 achieves >99.9% delivery rates for critical alerts. Detailed delivery logs provide visibility into exactly when and how alerts were received and acknowledged.

  • Multi-channel redundancy ensures delivery
  • Automatic escalation for unacknowledged alerts
  • Comprehensive delivery auditing

The workflow uses secure API connections between TheHive and SIGNL4 with proper authentication. All alert data remains encrypted in transit and at rest according to each platform's security standards.

Organizations should configure appropriate access controls, audit logs, and data retention policies for both systems. Consider masking sensitive alert details in mobile notifications while keeping full context available in TheHive for authorized users.

  • End-to-end encrypted communications
  • Principle of least privilege for API access
  • Optional sensitive data masking
