Key features. Everything you need to protect your infrastructure and users.
Splunk HEC
Push IOCs and SOC events through HTTP Event Collector. Configure in the dashboard — not a Splunkbase app.
Elastic
Index IOCs with the Elastic Bulk API from the dashboard. Not an Elastic Fleet package.
Microsoft Sentinel
Ingest indicators with Sentinel’s built-in TAXII connector. Optional Log Analytics destination for events.
STIX/TAXII Feeds
QRadar, Chronicle, and other SIEMs consume the TAXII 2.1 collections. No custom IsMalicious app.
API Integration
REST API for custom SIEM integrations.
Auto-Correlation
Correlate events with threat intelligence automatically.
Use cases. How security teams use this tool.
Event Enrichment
Add threat context to every security event.
Alert Correlation
Connect alerts to known threat campaigns.
Threat Detection
Create rules based on threat indicators.
Compliance
Document threat protection for audits.
Improve Your SIEM with Threat Intelligence
Your SIEM collects millions of events, but without context, it's just noise. Threat intelligence transforms your SIEM from a log aggregator into a true security detection platform. By enriching events with reputation data, correlating with known IOCs, and providing risk scores, our integration helps your SIEM generate meaningful alerts instead of drowning analysts in false positives.
What actually ships for SIEM platforms
We provide turnkey paths for the platforms you use — without inventing Splunkbase or Content Hub apps: - **Splunk**: HTTP Event Collector destination in the dashboard (Pro). Not a Splunkbase TA. - **Elastic**: Bulk API destination in the dashboard. Not an Elastic Fleet package. - **Microsoft Sentinel**: Built-in Threat Intelligence TAXII connector pointed at api.ismalicious.com, plus an optional Log Analytics destination for SOC events. - **IBM QRadar**: Consume STIX/TAXII 2.1 or the REST API. No native QRadar app. - **Google Chronicle**: Same — TAXII or REST. No Chronicle connector. See /integrations for the live list.
Real-Time Enrichment Without Performance Impact
Adding threat intelligence shouldn't slow down your SIEM. Our integrations are designed for performance: - **Asynchronous Enrichment**: Events are enriched in parallel without blocking ingest - **Intelligent Caching**: Frequently-seen IOCs are cached locally to reduce API calls - **Selective Enrichment**: Configure which event types and fields trigger enrichment - **Batch Processing**: High-volume environments can use batch enrichment for efficiency - **Low Latency**: Sub-50ms response times for real-time use cases We've tested our integrations at enterprise scale - millions of events per day without issues.
From Raw Logs to Specific Alerts
See how threat intelligence transforms SIEM operations: **Before**: "Connection to external IP 192.0.2.1 detected" **After**: "Connection to known C2 server (192.0.2.1) associated with APT29, high confidence malware communication" The enriched alert includes risk score, threat category, associated campaigns, and recommended response actions. Analysts can make decisions in seconds instead of spending hours researching.
