Frequently asked Expel
threat hunting questions
Automated detection catches known patterns. Expel’s threat hunters find the unknown, including attackers living off the land, abusing legitimate tools, or moving slowly to avoid detection. They can also find risks in your environment like misconfigurations and gaps. Expel threat hunters bring human expertise and cross-customer intelligence to surface activity that automated tools miss.
Expel runs monthly threat hunts across each customer’s environment, plus real-time hunts for emerging threats. Every hunt produces a written report with findings, methodology, and recommended remediations, delivered directly in Expel Workbench™. Coverage depth varies by package tier, but all customers receive actionable output from every hunt.
Expel’s threat hunters develop hypotheses informed by real attack patterns observed across our entire customer base, giving us visibility into emerging adversary behaviors that no single organization’s data could surface. Those hunts are also mapped to the MITRE ATT&CK framework. Hypotheses target living-off-the-land techniques, identity abuse, cloud persistence, and lateral movement, among other attacks.
SIEM rules fail more often than most teams realize. A 2025 CardinalOps report found that 10% of SIEM rules are broken and won’t fire during a real attack, due to misconfigured data sources or parsing errors. Expel threat hunting finds these blind spots and coverage gaps before attackers exploit them.
Expel threat hunting covers on-prem infrastructure, cloud, and SaaS applications, not just endpoints, identifying misconfigurations and posture gaps along the way. It runs as a proactive layer on top of Expel Managed Detection and Response (MDR), using Expel Workbench to manage hunts, findings, and remediation guidance in one place.
