Threat Feed Integration System
A unified platform for aggregating, normalizing, and correlating threat intelligence from multiple sources
Project Overview
The Threat Feed Integration System is a comprehensive platform designed to solve the challenge of managing multiple threat intelligence feeds with varying formats, quality, and update frequencies.
By consolidating over 15 different threat feeds into a unified system, this platform enables security teams to access high-quality, deduplicated, and contextualized threat intelligence through a single interface.
The system implements advanced correlation algorithms, automated scoring mechanisms, and customizable alerting to transform raw threat data into actionable intelligence that can be seamlessly integrated with existing security tools.
Key Outcomes
- Consolidated 15+ threat feeds into a unified platform
- Implemented automated scoring and prioritization
- Reduced false positives by 40%
- Created custom dashboards for threat visualization
- Improved threat detection response time by 65%

Implementation Details
The system integrates with a diverse set of threat intelligence feeds, each providing unique insights into the threat landscape.
| Feed Name | Category | Type | Format | Reliability |
|---|---|---|---|---|
| AlienVault OTX | Commercial | Multi-vector | STIX/TAXII | High |
| MISP Community | Open Source | Multi-vector | MISP | Medium |
| Recorded Future | Commercial | Multi-vector | API | High |
| VirusTotal | Commercial | Malware | API | High |
| PhishTank | Open Source | Phishing | CSV/API | Medium |
| Spamhaus | Open Source | Spam/Malware | DNS/API | High |
| Abuse.ch | Open Source | Malware/C2 | CSV/API | Medium |
| Cisco Talos | Commercial | Multi-vector | API | High |
| ThreatConnect | Commercial | Multi-vector | API/STIX | High |
| IBM X-Force | Commercial | Multi-vector | API | High |
Feed Processing Workflow
Each feed is processed through a dedicated connector that handles authentication, data retrieval, and initial parsing. The system supports both pull-based (scheduled polling) and push-based (webhook) data collection methods, with configurable update frequencies based on the feed's update cadence.
Feed reliability scores are dynamically calculated based on historical accuracy, timeliness, and coverage, which influences the confidence scoring of indicators sourced from each feed.
Results and Impact
Reduction in false positives
Compared to previous threat intelligence solution
Faster threat response
Reduced time from detection to mitigation
Integrated threat feeds
Consolidated into a single platform
Increase in detection coverage
Broader visibility across threat landscape
"The Threat Feed Integration System has transformed how our security operations team consumes and acts on threat intelligence. Before implementing this solution, our analysts spent hours manually correlating data from different sources. Now, they have a unified view of the threat landscape with actionable intelligence that integrates directly with our security controls. The reduction in false positives and improved detection capabilities have significantly enhanced our security posture."
