Every organization has a different threat profile. Industry, geography, infrastructure, business operations, and the broader technology ecosystem all influence which adversaries and threats matter most.
The challenge is putting threat intelligence to work at scale to identify the greatest threats to each business. The intelligence that security teams rely on is as varied as the threats they face. Organizations draw from commercial threat intelligence providers, industry information sharing and analysis centers (ISACs), government sources, open-source research, trusted partners, and indicators uncovered through their own threat hunting and incident response efforts.
Modern security operations need a “Bring your own intelligence” strategy to manage these disparate sources. CrowdStrike Falcon® Next-Gen SIEM brings threat intelligence and security telemetry together in Third-Party IOC Management, a new feature that enables organizations to incorporate their own intelligence directly into detection and investigation workflows.
By centralizing the ingestion, curation, and lifecycle management of third-party indicators, security teams can operationalize the intelligence most relevant to their environment alongside CrowdStrike’s adversary intelligence and telemetry from both the CrowdStrike Falcon® platform and third-party sources.
Turn Threat Intelligence into a Detection Advantage
Valuable indicators are often scattered across spreadsheets, ticketing tools, and threat intelligence platforms, which are often disconnected from the security telemetry that analysts rely on. Manually importing and maintaining indicators across multiple tools creates operational overhead. Limited real-time correlation and outdated indicators of compromise (IOCs) can delay threat detection, generate unnecessary alerts, and slow investigations.
Instead of manually moving indicators between disconnected tools, security teams can manage their intelligence within Falcon Next-Gen SIEM, reducing operational complexity and accelerating the path from threat intelligence to actionable security insights.
Figure 1. See how Third-Party IOC Management in Falcon Next-Gen SIEM helps security teams ingest, manage, and correlate their own threat intelligence with security telemetry to accelerate detection and investigation.
Third-Party IOC Management helps eliminate the operational barriers that slow detection and investigation through four key capabilities:
- Eliminates manual IOC onboarding: Ingest and manage third-party IOCs, including IP addresses, domains, URLs, and file hashes, from commercial intelligence providers, industry sharing communities, and internal investigations. With support for STIX/TAXII, APIs, and direct uploads, security teams can streamline intelligence onboarding, automatically consolidate duplicate indicators across sources, and reduce the effort required to maintain intelligence across disparate tools.
- Accelerates detection and threat hunting: Put third-party intelligence to work in Falcon Next-Gen SIEM through curated indicator lists that are automatically updated. Security teams can use these indicators in correlation rules and threat hunting searches to identify known malicious infrastructure and suspicious activity across security telemetry, accelerating detection and investigation without manually maintaining separate indicator lists.
- Reduces alert noise with automated IOC lifecycle management: Maintain control over third-party indicators with expiration settings and management capabilities that help prevent outdated intelligence from creating unnecessary noise. By keeping IOC collections current and relevant, security teams can reduce manual maintenance, minimize false positives associated with stale indicators, and focus investigations on threats that matter.
- Expands detection coverage with organization-specific intelligence: Extend CrowdStrike’s adversary intelligence and AI-native detection capabilities with intelligence specific to your organization. By bringing third-party and proprietary indicators together with CrowdStrike intelligence and security telemetry, teams can broaden detection coverage and investigate threats with context that reflects both the global threat landscape and their unique environment.
To see how these capabilities can work together in practice, consider a common industry-specific threat intelligence scenario. A financial services organization receives indicators associated with a targeted phishing campaign from an industry information-sharing community. With Third-Party IOC Management, the security team can bring these indicators into Falcon, consolidate duplicates, and manage their lifecycle while using them in Falcon Next-Gen SIEM to search security telemetry and build correlation rules to identify potentially related activity. This turns industry-specific intelligence into actionable detection and investigation context without manually distributing indicators across disconnected tools.
Connect Intelligence to Accelerate Security Operations
With Third-Party IOC Management built into Falcon Next-Gen SIEM, organizations can maximize existing threat intelligence investments while reducing the complexity of maintaining disconnected tools and integrations. Rather than replacing the intelligence sources they rely on, security teams can bring that intelligence into the platform where they detect and investigate threats.
This consolidation also reduces the operational burden on analysts and detection engineers. Fewer manual handoffs, less context switching, and centralized IOC management mean teams can spend less time maintaining intelligence workflows and more time identifying suspicious activity, investigating threats, and taking action.
As security operations evolve toward the agentic SOC, the quality of AI-driven investigations and decisions will increasingly depend on access to relevant, timely, and contextualized security data. AI agents need more than telemetry alone; they need intelligence that helps explain what suspicious activity means within an organization’s unique threat landscape.
By bringing third-party IOCs together with CrowdStrike’s adversary intelligence and security telemetry in Falcon Next-Gen SIEM, organizations can reduce data fragmentation and build a richer foundation for AI-driven security operations. This convergence creates opportunities for AI agents to correlate indicators with security events, enrich investigations with threat context, and support faster, more informed response decisions.
