OSINT for Security Teams
When a new CVE hits CISA's KEV list, your Slack channel knows within minutes. When threat actors shift tactics, your SIEM has the context before the analyst finishes their coffee.
The Problem
SOC Alert Fatigue Is Real
Your team gets hundreds of alerts per day. Most are noise. The ones that matter get buried.
Security operations centers run on alerts. The average SOC processes over 10,000 alerts per day. Analysts spend most of their time triaging and dismissing false positives instead of investigating real threats. By the time a genuine threat is identified, response time has already slipped.
OSINT adds another layer. Your team needs to track CISA advisories, vulnerability disclosures, threat actor TTPs, and geopolitical events that could indicate targeted attacks. That means more feeds, more tabs, more noise.
Sentinel does not replace your SIEM. It feeds your SIEM with pre-analyzed, deduplicated, context-enriched intelligence from 20+ public sources — so your existing tools get better inputs.
Capabilities
How Security Teams Use Sentinel
Cyber Threat Feed Ingestion
CISA Known Exploited Vulnerabilities (KEV), abuse.ch threat data, and CVE disclosures ingested automatically. New entries appear as alerts within minutes of publication, not hours.
Webhook SIEM Integration
Every alert can be delivered as a structured JSON webhook to your SIEM, SOAR, or custom tooling. Parse it directly into Splunk, Elastic, or Sentinel (Microsoft) incident queues.
Automated Alert Triage
AI agents assess severity using context, not just CVSS scores. A critical CVE affecting software you don't run is noise. A medium CVE affecting your exact stack version is urgent. Agents know the difference.
Attack Surface Correlation
Cross-reference cyber indicators with physical-world events. A spike in threat actor activity from a specific region combined with geopolitical escalation in that region is a different risk profile than either signal alone.
Multi-Domain Awareness
SOC teams don't operate in a vacuum. Infrastructure threats come from earthquakes, weather events, supply chain disruption, and conflict zones — not just cyber. Sentinel monitors all of it.
API-First Automation
Query events, entities, and alerts programmatically. Build custom dashboards, feed Jupyter notebooks, or trigger automated runbooks. Full REST API with rate limits by tier.
Scenarios
Real-World Examples
What Sentinel delivers to a SOC in practice.
CISA KEV Alert
Scenario
CISA adds CVE-2026-XXXX to the Known Exploited Vulnerabilities catalog at 14:23 UTC.
Sentinel Response
Your Slack #security-alerts channel gets a message at 14:25 UTC with the CVE ID, affected software, exploitation status, remediation deadline, and a direct link to the CISA advisory. Your SIEM receives a structured webhook simultaneously.
Geopolitical Threat Correlation
Scenario
GDELT detects a 300% increase in CAMEO code 17-19 events (coercion and military force) in a region where your company operates data centers.
Sentinel Response
Sentinel flags the escalation with a composite alert: regional instability rising, specific event codes and sources cited, recommended actions for infrastructure teams. The geopolitical context arrives before it hits mainstream news.
Infrastructure Risk from Natural Events
Scenario
USGS reports a magnitude 6.1 earthquake within 50km of a major Internet exchange point in the Pacific Rim.
Sentinel Response
The seismic agent fires an alert. The orchestration layer cross-references with infrastructure data and identifies potential impact to submarine cable landing stations in the area. SOC gets early warning about possible latency or connectivity issues before they appear in monitoring dashboards.
Integration
Fits Your Existing Stack
Sentinel is not a replacement. It is an input layer.
Sentinel delivers intelligence via webhooks, REST API, and direct channel integrations. It works alongside your existing tools:
- Splunk (via webhook)
- Elastic SIEM (via webhook)
- Microsoft Sentinel (via webhook)
- PagerDuty (via webhook)
- Slack (native integration)
- Discord (native integration)
- Jira (via webhook + automation)
- Custom SOAR playbooks (via REST API)
