Sigma InfoSec
Managed Threat Hunting

Catch threats alerts can miss

No security tool is perfect. Sophisticated attackers hide in your environment using stolen credentials, legitimate IT tools, and covert Microsoft 365 rules. We deliver a fully managed, cross-domain threat hunting service — proactively searching your endpoints, identities, and cloud workspaces to neutralize dormant threats.

Weeks
The Reactive Trap

The danger of relying solely on reactive security

Weeks of silent dwell time while automated tools see nothing

Standard automated security tools leave critical gaps that cybercriminals exploit to maintain persistent access.

MFA BYPASS

Stolen session tokens & identity abuse

Modern attackers bypass MFA by stealing session cookies. Automated tools see valid logins; proactive hunters identify the anomalous behavior.

DWELL TIME

Silent dwell time

Adversaries spend weeks inside networks mapping infrastructure, exfiltrating data, and creating covert backdoor access without triggering standard threshold alerts.

BEC RISK

Microsoft 365 exploitation

Rogue OAuth applications, malicious inbox forwarding rules, and mailbox permission changes in M365 frequently fly under the radar of traditional EDR tools.

ALERT BURNOUT

Alert burnout

Security teams spend 100% of their time chasing low-level automated alerts, leaving no resources for hypothesis-driven threat hunting.

The Service

Cross-domain hunting, fully managed

We don't wait for alerts to ring. We actively hunt hidden adversaries across your endpoints, identities, and Microsoft 365 environment before they strike.

Dual-engine hunting architecture

SentinelOne Wayfinder Threat Hunting — powered by AI telemetry and Google Threat Intelligence — combined with our proprietary M365 hunting engine built on real-world incident response data.

Workspace & identity coverage

Stop threats that bridge endpoints and cloud workspaces — BEC, rogue OAuth application consents, session token hijacking, and lateral movement in M365.

Hypothesis-driven human execution

Specialized threat hunters continuously test hypotheses against your historical telemetry to expose silent, dwell-time attacks that bypass automated controls.

Fully managed & turnkey

Zero hunting queries to write, zero rule tuning, zero manual log queries. We uncover the threat and execute immediate containment.

How It Works

Identify, isolate, eliminate

We continuously search your environment to expose adversary presence — then remove it.

1

Continuous telemetry correlation

We integrate SentinelOne Singularity telemetry with your Microsoft 365 environment, collecting process execution, network connections, identity logins, and mailbox audit logs in real time.

2

Proactive hypothesis-driven hunting

Our analysts test advanced threat hypotheses against your telemetry using SentinelOne Wayfinder, Purple AI, and our internal library of proprietary Microsoft 365 hunting queries to uncover stealthy activity.

3

Immediate containment & remediation

When a hidden threat or compromised identity is exposed, our team immediately isolates the impacted endpoint, revokes compromised M365 session tokens, removes malicious rules, and provides root-cause forensics.

Dual-Engine Defense

SentinelOne Wayfinder + our proprietary M365 engine

Our hunting capabilities combine global platform intelligence with specialized cloud workspace hunting.

01

SentinelOne Wayfinder Threat Hunting

Combines SentinelOne's global agentic telemetry, Purple AI conversational analytics, and Google Threat Intelligence to track adversary tactics across endpoints and cloud workloads.

02

Proprietary Microsoft 365 Threat Engine

Custom-built detection queries developed from real-world incident response experience — detecting BEC transport rules, rogue OAuth consents, session token hijacking, and Exchange & SharePoint exfiltration.

03

Hypothesis-Based Investigations

Continuous manual reviews by expert threat hunters who hunt specifically for Living-off-the-Land (LotL) techniques that bypass automated detection logic.

04

Turnkey Threat Intelligence Updates

New threat actor TTPs identified anywhere in the world are converted into hunting queries across your environment within minutes.

The Difference

DIY threat hunting vs. fully managed

In-House (DIY) Threat Hunting
Sigma Fully Managed
Hunting scope
Limited to endpoint EDR telemetry; ignores cloud identity and M365 activity
Full cross-domain visibility across endpoints, identity, cloud workloads, and Microsoft 365
Threat intelligence
Public IoCs and basic threat feeds — missing emerging global adversary TTPs
SentinelOne Wayfinder + Google Threat Intelligence + proprietary M365 field intelligence
Microsoft 365 defense
Manual search queries in M365 Purview; unmonitored BEC and token theft risk
Continuous automated and manual hunting with custom, battle-tested M365 detection queries
Human expertise
Hire dedicated, specialized threat hunters ($200k+ per hunter annually)
Elite team of global and internal threat hunters working continuously on your behalf
Hunting methodology
Reactive triage driven only when high-severity alerts are triggered
Proactive, hypothesis-driven hunting based on real-world threat actor behaviors and zero-days
Execution & remediation
Identifies anomalies but leaves investigation and containment to internal IT
End-to-end hunting, forensic analysis, immediate threat isolation, and guided remediation
