By leveraging existing investments in security technologies, Cisco XDR enables organizations to consolidate their defenses, reduce silos, and achieve a more cohesive security posture. The result is faster threat detection, streamlined operations, and improved incident response efficiency.

Cross-Platform Advantages

Cisco XDR (Extended Detection and Response) is designed to unify and analyze data from both Cisco and non-Cisco security tools, enabling organizations to create a comprehensive security ecosystem. Here’s how XDR facilitates this integration:

1. Integration with Cisco Security Tools

Cisco XDR natively integrates with Cisco's security solutions, which provide telemetry data across various domains:

• Endpoint: Cisco Secure Endpoint (formerly AMP for Endpoints) delivers detailed endpoint activity and threat detection data.
• Network: Cisco Secure Network Analytics (formerly Stealthwatch) provides network traffic analysis and anomaly detection.
• DNS and Web: Cisco Umbrella offers DNS-layer security and insights into web traffic.
• Email Security: Cisco Secure Email monitors and analyzes email communications for phishing, spam, and malware.
• Identity and Access: Cisco Duo ensures secure authentication and visibility into user activities.
• Threat Intelligence: Cisco Talos supplies real-time threat intelligence to enrich incident context.

These tools feed telemetry into XDR, which normalizes, correlates, and analyzes the data in a unified dashboard.

2. Integration with Non-Cisco Security Tools

Cisco XDR is designed to work in heterogeneous environments by integrating third-party security tools using the following approaches:

1. APIs and Prebuilt Connectors

• Prebuilt Integrations: Cisco provides prebuilt connectors for widely used third-party tools like endpoint detection and response (EDR) platforms, SIEM solutions, and identity management systems (e.g., CrowdStrike, Splunk, Okta).
• Custom APIs: Organizations can use RESTful APIs to connect additional tools that might not have prebuilt integrations.

1. Open Ecosystem Support

Cisco XDR is built on an open platform, allowing the ingestion of data from any tool that supports industry-standard protocols like:

• Syslog: For log forwarding.
• JSON/REST: For structured data exchanges.
• STIX/TAXII: For sharing threat intelligence.

1. Data Aggregation

Non-Cisco tools feed raw telemetry, alerts, and event data into Cisco XDR, which:

• Normalizes the data to a consistent format.
• Correlates events with Cisco tool telemetry to identify complex attack patterns.

3. Unified Threat Detection

Cisco XDR combines data from all sources to enhance threat detection:

• Cross-Platform Correlation: Links activity from endpoints, networks, and cloud services, whether the data comes from Cisco or non-Cisco tools.
• Threat Intelligence Enrichment: Uses Cisco Talos and third-party threat feeds to provide context to incidents detected by non-Cisco tools.
• Behavior Analytics: Identifies anomalies by analyzing aggregated behavior across tools.

4. Incident Management and Automation

Cisco XDR simplifies incident response by coordinating actions across diverse tools:

• Unified Playbooks:

Integrates response playbooks that execute actions across Cisco and non-Cisco tools, such as isolating endpoints (e.g., using CrowdStrike or Microsoft Defender) or blocking IPs via third-party firewalls (e.g., Palo Alto Networks or Fortinet).

• Centralized Orchestration: Cisco XDR acts as the central control plane to execute response actions across both Cisco and non-Cisco tools, eliminating the need to switch between multiple platforms. For example:
  • Triggering an endpoint quarantine via non-Cisco EDR tools like CrowdStrike or SentinelOne.
  • Reconfiguring non-Cisco firewalls (e.g., Fortinet, Check Point) to block malicious traffic.
  • Resetting user credentials through identity providers like Okta or Azure AD.
• Automated Workflows: Cisco XDR supports automated workflows to manage common security incidents. For example:
  • If a phishing email is detected by a third-party email security tool, Cisco XDR can automatically isolate impacted endpoints and alert administrators.
