Sigma InfoSec
Managed Incident Response

Breach answers in hours, not days.

When a security incident hits, every minute of uncertainty increases financial and operational damage. We deliver fully managed Incident Response & Digital Forensics powered by proprietary AI and managed by senior SOC analysts. Once a verified threat is isolated, our team retraces the adversary's actions activity-by-activity to identify root cause, map exposure scope, and harden your environment the very same day.

The Response Gap

The operational risk of slow incident response

2wks the standard forensic turnaround — we deliver root-cause answers in hours

Traditional forensic retainers and delayed investigation workflows create severe risk during a breach.

DOWNTIME

Prolonged system downtime

Waiting days for external forensic consultants to analyze disk images halts business operations and inflates recovery costs.

DEADLINE RISK

Regulatory & insurance deadlines

Cyber insurance carriers and regulatory frameworks (SEC, HIPAA, GDPR) enforce strict incident notification windows that standard 2-week forensic turnarounds miss.

SCOPE GAP

Incomplete scope identification

Isolating a single infected machine without understanding how the attacker gained initial access leaves dormant backdoors open for secondary attacks.

EVIDENCE LOSS

Evidence degradation

Delayed investigations risk losing volatile memory logs, transient network connections, and temporary cloud identity artifacts.

The Service

Contain instantly. Understand completely.

From verified true-positive containment to complete forensic root-cause analysis in hours, not days.

Immediate true-positive containment

The moment a threat is verified as a true positive, our 24/7 SOC takes surgical isolation actions to neutralize lateral movement and stop data exfiltration instantly.

AI-accelerated forensic retracing

Our proprietary AI engine parses millions of system events, process trees, and network logs in minutes — retracing the adversary's exact path activity-by-activity.

Human SOC root-cause discovery

Veteran IR analysts validate AI telemetry to identify the exact initial access point — weaponized email, stolen session cookie, unpatched vulnerability — and full exposure scope.

Same-day hardening & recovery

We collaborate directly with your team to remediate vulnerabilities, enforce security baselines, and deliver audit-ready forensic reporting within hours.

How It Works

From containment to complete clarity

Our emergency response methodology moves seamlessly from immediate containment to complete post-incident hardening.

1

Verified true-positive containment

The moment a threat is validated as a true positive, our SOC isolates impacted endpoints, revokes compromised identity sessions, and severs malicious C2 connections to prevent lateral movement.

2

Deep telemetry & timeline retracing

Our proprietary AI ingests endpoint process trees, M365 audit logs, network DNS, and identity telemetry to reconstruct the adversary's step-by-step execution path across your entire estate.

3

Root-cause analysis & rapid hardening

Human SOC analysts confirm the initial entry vector, identify all affected systems and users, deliver executive-ready forensic reporting, and work directly with your team to harden your network within hours.

Engine Room

Powered by proprietary AI + veteran IR analysts

Our Incident Response service combines proprietary automation with deep human expertise to deliver unprecedented investigation speed.

01

Proprietary AI Forensic Engine

Automatically parses memory artifacts, event logs, execution flags, and cloud audit logs to construct complete attack timelines in minutes.

02

Cross-Domain Retracing

Correlates activity across endpoints, Active Directory / Entra ID, Microsoft 365, cloud gateways, and network DNS to map the full extent of adversary access.

03

Initial Access Identification

Pinpoints the exact entry point — whether a phishing email, stolen session cookie, vulnerable public asset, or rogue third-party connection.

04

Scope & Impact Mapping

Identifies every account, file access event, registry change, and lateral connection touched by the threat actor.

05

Collaborative Remediation & Hardening

Delivers actionable, prioritized steps to patch exploited gaps, eliminate persistent backdoors, and prevent recurrent compromises.
