Sigma InfoSec
Managed Dark Web Monitoring

Find stolen credentials before attackers use them.

We deliver a fully managed dark web monitoring service, ingesting recaptured criminal intelligence to identify stolen credentials and active session cookies, so you can invalidate compromised logins before attackers breach your perimeter.

Months
The Identity Blind Spot

The dangerous flaws of legacy dark web scanners

Months late — by the time public scanners alert you, access brokers have already sold your credentials

Relying on basic breach notification services or passive dark web scanners leaves critical identity security gaps across your organization.

MFA BYPASS

Stolen cookies bypass MFA

Modern attackers don't just crack passwords — they steal session cookies with infostealer malware. These cookies let adversaries hijack active sessions without triggering MFA prompts.

BYOD BLIND SPOT

Personal & BYOD device blind spots

Employees checking work email or cloud apps from infected personal laptops expose corporate credentials that internal EDR agents never see.

MONTHS LATE

Months-late alerts

Standard scanners search public dark web forums. By the time compromised credentials appear there, criminal access brokers have already sold them to ransomware operators.

NO REMEDIATION

No remediation execution

Receiving a 500-line CSV report of leaked passwords leaves your IT team struggling to identify which accounts present active risks.

The Service

Identity defense, not breach notification

We neutralize compromised credentials and stolen session cookies straight from criminal networks — before adversaries can bypass your MFA or breach your cloud.

Recaptured — not just scanned — intelligence

Infiltrate closed criminal channels, infostealer malware logs, and phishing kits to capture stolen identity data months before it hits public leak sites.

Session hijacking & MFA defense

Go beyond static passwords. Recapture active session cookies, webhooks, and auth tokens to invalidate compromised sessions before attackers hijack authenticated access.

Third-party & unmanaged device coverage

Protect corporate access originating from unmanaged home computers, BYOD devices, supply chain vendors, and contractors.

Active SOC remediation

Shift from passive notification to active identity defense. Our SOC revokes compromised sessions, enforces targeted password resets in Okta/Entra ID, and validates remediation.

How It Works

From criminal networks to closed sessions

We eliminate identity-based attack vectors before cybercriminals can monetize them.

1

Recapture & ingestion

Our platform continuously recaptures stolen data from active infostealer malware infections (Lumma, RedLine, Vidar), phishing kit outputs, and private criminal exchanges — in real time.

2

24/7 SOC triage & analysis

Our security team correlates recaptured data against your active workforce (Entra ID, Okta, M365). We verify plaintext passwords, evaluate cookie freshness, and determine the exact exposure radius.

3

Active remediation & containment

When active session cookies or high-risk credentials are detected, our SOC immediately revokes active sessions in your IdP, triggers automated password resets, and validates account safety.

Engine Room

Powered by SpyCloud Intelligence

Our managed identity operations leverage SpyCloud, the industry leader in recaptured darknet identity data and cybercrime prevention.

01

World's Largest Recaptured Dataset

Access to tens of billions of darknet assets, recapturing data directly from criminal sources before it reaches public marketplaces.

02

Infostealer Malware Telemetry

Ingests complete botnet log telemetry across 100+ malware families, exposing every application, credential, and cookie stored on an infected machine.

03

Automated IdP Integrations

Direct API orchestration with Microsoft Entra ID, Okta, Ping Identity, and M365 for automated session revocation and policy enforcement.

04

Plaintext Credential Matching

Over 80% of exposed credentials are delivered in human-readable plaintext through automated cracking, allowing immediate risk verification.

05

VIP & Executive Protection

Specialized monitoring for C-suite personnel and critical administrators to protect personal email addresses, personal devices, and high-privilege credentials.

The Difference

DIY monitoring vs. fully managed identity defense

Standard / DIY Monitoring
Sigma Fully Managed
Data sourcing
Scans public paste sites and open dark web forums long after a breach occurs
Recaptures data directly from closed criminal networks, infostealer malware logs, and phishing kits in real time
Monitored assets
Limited to basic username and password pairs
Captures plaintext credentials, active session cookies, MFA tokens, API keys, and device telemetry
MFA protection
Zero protection against session hijacking or cookie theft
Recaptures stolen session cookies and immediately invalidates them in your Identity Provider
Unmanaged / BYOD scope
Cannot track exposures originating from unmanaged home computers or contractor devices
Tracks identity exposure across every endpoint where corporate credentials were used — managed or unmanaged
Remediation & response
Sends automated email alerts, leaving credential resets and session revokes to you
Turnkey SOC action: continuous triage, automated IdP session termination, forced password resets, and VIP protection
Executive / VIP coverage
Treats executive exposure the same as any general domain user
Enhanced VIP Guardian monitoring with specialized privacy controls for personal executive accounts
