The Problem
Attackers abuse approved tools and valid credentials
Adversaries increasingly blend into approved internet and cloud activity by using legitimate tools, valid credentials, and encrypted channels to look normal. Traditional alerting can miss living off trusted sites (LOTS) attacks—when attackers abuse reputable services to host payloads or move data—because the traffic appears routine unless you correlate subtle anomalies across users, destinations, and time. Most teams lack the expertise and bandwidth to proactively hunt this activity, and ingesting network data into a SIEM to analyze it is often cost-prohibitive.
Product Overview
Zscaler Threat Hunting uses Zscaler Internet Access (ZIA) telemetry to find behaviors that indicate compromise across web and cloud activity. Our experts investigate, enrich, and prioritize findings so your team can focus on response. Because Zscaler Threat Hunting keeps ZIA telemetry within Zscaler, teams avoid data exfiltration and SIEM ingestion costs while identifying early attacker activity sooner.
Benefits
Add detection coverage and refocus on response
Catch advanced attacks earlier
Reveal attacker activity in trusted tools and sites by hunting directly in SSL-inspected traffic.
Expand coverage without SIEM ingestion
Gain new detection insights from ZIA logs without the cost of ingesting them into your SIEM.
Gain more time for response
Our hunters detect and investigate threats so your team can stay focused on containing and remediating.

FAQ
Threat hunting is a proactive approach to finding potential threats and vulnerabilities in an organization's network and systems. It combines security analysts, threat intelligence, and advanced technologies that analyze behavior, spot anomalies, and identify indicators of compromise (IOCs) to detect what traditional security tools may miss. They strive to detect and neutralize threats early to minimize their potential impact. Learn more.
Threat intelligence is the collection, analysis, and dissemination of information about suspected, emerging, and active cyberthreats, including vulnerabilities, threat actors’ tactics, techniques, and procedures (TTPs), and indicators of compromise (IOCs). Security teams use it to identify and mitigate risk, reinforce security controls, and inform proactive incident response. Learn more.
Attackers increasingly blend into normal internet and cloud traffic using legitimate tools and valid credentials, often making them undetectable by traditional security tools and controls. Hunting in ZIA's SSL-inspected telemetry lets experts correlate subtle anomalies across users, destinations, and time to catch threats before they reach your endpoints. And when a threat is confirmed, that same network visibility helps scope the full extent of attacker activity, helping you understand and minimize organizational damage.
