At Expel, we’ve always believed that great security shouldn’t force you into rigid technology choices. Our “bring-your-own-tech” philosophy is central to how we deliver managed detection and response (MDR), especially when it comes to your security information and event management (SIEM) platform. You’ve invested in your SIEM, and our goal is to maximize that investment by integrating seamlessly.

That’s why we’re excited to announce the expansion of our SIEM coverage, further solidifying Expel’s position as a leader in MDR flexibility. We’ve officially launched advanced support for Palo Alto Networks Cortex® XSIAM this month.

 

What Tier 1 coverage means for XSIAM customers

Adding XSIAM to our list of supported SIEMs means organizations using these platforms can now directly leverage them within Expel’s 24×7 MDR service. Our integration provides a robust foundation for detection and investigation, and includes:

  • Custom detections: We provide Expel-written detections, customized for your XSIAM environment.
  • Vendor detections: We monitor, triage, and investigate alerts generated by the native detection capabilities within your SIEM.
  • Tuning & onboarding reports: We work with you to fine-tune detection rules, minimize noise, and ensure alerts are relevant, backed by clear reporting during onboarding and beyond.
  • Investigative source via SIEM integrations: Our analysts leverage the rich data within your XSIAM platform as a primary source during security investigations, ensuring context and depth.

 

Unlocking value from your existing security stack

This expanded support means more organizations can benefit from Expel MDR without needing to replace their chosen SIEM. By offering advanced integration support for XSIAM, we empower your security team by:

  • Offering unmatched flexibility: Choose the security tools that best fit your environment and strategy, knowing Expel can integrate with them.
  • Providing comprehensive visibility: Combine the strengths of your SIEM data and detections with Expel’s expert analysis and response capabilities.
  • Ensuring consistency: Receive the same high-quality Expel MDR experience, regardless of your underlying SIEM technology.

 

Continuing our commitment to choice

Adding XSIAM support is another step in our ongoing mission to provide the most flexible and effective MDR service on the market. We meet you where you are, integrating with your key security tools to provide unified visibility and rapid, decisive response.
