DETECTION COVERAGE
Threat detection without the gaps
Your tools aren’t broken—they’re just not talking to each other. We unify signals across ten attack surfaces. Fewer alerts. Faster answers. Nowhere to hide.
Our Approach
We find the needles, not add to the haystack.
Most vendors add alerts to your pile. We cut through it with cross-surface detections that correlate in real-time, finding threats at every stage.
Coverage across your environment
Attackers ignore your boundaries. We integrate across your entire stack—EDR, identity, cloud, and more—connecting them all to see threats others miss.
Depth through threat detection engineering
We layer thousands of Expel detections on your stack to catch cross-surface threats early. Your tools detect. We connect. Attackers get kicked out.
Intelligence that scales protection
Our detection engineers turn threat intel into new detections and ML models. If one customer encounters a threat, the entire base gains immunity.
"Expel has helped improve the signal to noise ratio, which allows our team to focus on high fidelity alerts. ”
HOW IT WORKS
From noise to narrative
We don’t just collect your alerts. We connect them. Here’s how we turn your security stack into threat detection coverage that actually works.
We connect via API, webhook, or SIEM—pulling real-time telemetry across your entire environment. No rip-and-replace required.
We standardize data so authentication events look identical whether from Okta or AWS. That’s what enables true cross-surface correlation.
We layer in threat intel, behavioral baselines, and attack patterns—turning isolated events into threat detection with full context.
2,450+ Expel-written detections fire on attacker techniques, not isolated events. We find patterns spanning your environment to show how threats move.
We investigate every credible threat and give you details. You get “here’s what happened and how to fix it,” not “something looks weird, good luck.”
HOW WE’RE DIFFERENT
Detection that gets smarter
with every threat
We pioneered cross-surface detection while others were stuck on point products. Our detections are intel-driven and evolve constantly, not eventually.
Detections refined by real attacks, not lab scenarios.
Every detection is tuned with real threat intel and mapped to MITRE ATT&CK. We write detections based on real life—not what looks good on a demo.
Cloud expertise. Not retrofitted from EDR.
Nine years of high-fidelity cloud detection. First to support Kubernetes. We catch threats endpoint-first platforms weren’t built to see.
Threat intel that evolves detections
Real attacks tune our detections continuously. When one customer faces a threat, every customer gains protection—that’s collective defense at scale.
Fidelity we can actually act on
Layered detections and intelligent noise reduction deliver the precision needed to act on your behalf—stopping threats before they cause damage.
Complete transparency into detection logic
You get full visibility into why we fired an alert, the metrics behind it, and the logic behind our actions.

Frequently Asked Questions
Expel layers thousands of home-grown detections on your stack to catch cross-surface threats early. By correlating signals from endpoint, identity, cloud, and email simultaneously, Expel surfaces attacks early in the attack chain that may have otherwise gone undetected.
Yes. Expel’s detection library maps to the MITRE ATT&CK framework, giving you a clear picture of which tactics and techniques you’re covered for and where gaps may exist. This is valuable for security assessments, compliance reporting, and board-level communication.
Expel’s detection library is continuously updated based on new threat intelligence, emerging attack techniques, and changes to your environment. When you add a new integration, Expel ships detection content for it. When a new attack technique emerges, detection logic updates across all applicable customers automatically.
Expel’s AI triage layer filters alerts before they reach analysts, dramatically reducing false positive volume. When a false positive does surface, analysts document and tune the relevant detection rule in Expel’s detection library, sharpening coverage precision across your environment over time.
