Cyber Threat Intelligence Challenges

Organizations struggle to centrally manage reliable threat intelligence due to rapidly increasing threat data and a complex attack surface. Correlating, analyzing, and transferring data from different sources to operations teams creates a significant operational burden.

Manual processing of threat indicators, data mismatch across various security tools, and scattered intelligence management make it difficult for SOC teams to take swift action. This situation can lead to the late detection of threats. The lack of real-time threat visibility also makes it difficult for organizations to develop a proactive security approach.

How Does OpenCTI Work?

OpenCTI correlates and analyzes data collected from different threat intelligence sources on a centralized platform and provides operational visibility to security teams. It supports fast decision-making processes by establishing links between IOCs, threat actors, and attack campaigns.

Workflow

1. Collect Data

  • External threat sources are connected.
  • IOC and STIX data are imported.
  • Automated data collection processes are operated.
  • Data is received from security tools.

2. Analyze and Correlate

  • Threat actors are matched.
  • Campaign relationships are created.
  • IOC correlation analysis is performed.
  • Risk levels are evaluated.

3. Share and Manage

  • Data is shared between teams.
  • Centralized incident management is provided.
  • Report and analysis outputs are generated.
  • Continuous threat tracking is performed.

Continuous Improvement

Thanks to its open-source nature and wide integration support, OpenCTI quickly adapts to the evolving threat landscape. It supports enterprise security operations with its scalable architecture.
