SENTRY — Threat Hunting

Threat Hunting Is What Happens Between Alerts

Automated detection catches known and previously seen attack patterns. Threat hunting is a human-led, hypothesis-driven search for the threats that don’t trigger an alert at all — the ones already inside your environment.

Hypothesis-Driven, Not Reactive

Assume the Breach Already Happened

Proactive threat hunting starts from an uncomfortable assumption: that an undiscovered compromise of some kind has already occurred, and the job is to find evidence of it before it causes damage — not to wait for a tool to flag it.

A hunt typically starts with a hypothesis grounded in current attacker techniques (for example, mapped to MITRE ATT&CK) — “if a specific credential-theft technique were used here, what would the evidence look like in our logs?” — and an analyst investigates systems, network traffic, and log data to prove or disprove it.

This is deliberately different work from what automated detection does. Automated tools are continuous processes that flag known and previously seen attack signatures. Threat hunters go looking for advanced, novel, or slow-moving techniques specifically designed to blend into normal activity and avoid triggering those signatures in the first place.

Why Human Expertise Doesn’t Get Replaced Here

Forming a good hunting hypothesis relies on human understanding of how an attacker actually thinks and operates through a multi-stage intrusion — reconnaissance, initial access, persistence, lateral movement, exfiltration. That judgment is what turns raw telemetry into a specific, testable question, and it’s the part of threat hunting that automated tooling doesn’t replicate. Balancing automated detection with human hunting is what lets a SOC catch attack patterns that mimic normal activity closely enough to slip past signature-based tools alone.

Frequently Asked Questions

Is threat hunting the same as incident response?
No. Incident response reacts to a confirmed incident. Threat hunting proactively searches for evidence of compromise before any alert has fired — it’s a preventive, investigative discipline, not a reactive one.
Do we need an EDR/XDR platform for threat hunting to work?
Effectively yes — hunters need rich telemetry to investigate against. See our MDR vs. EDR vs. XDR breakdown for how these layers relate.
Is threat hunting included in standard MDR?
It varies by provider and tier — proactive hunting is frequently a premium-tier feature rather than a baseline inclusion. See our MDR pricing page for how that affects cost.
