Identity Security, Reinvented: How Stellar Cyber ITDR Stops Credential-Based Attacks Before They Spread

Guest blog courtesy of Stellar Cyber.

In today’s hybrid world, identity is the new perimeter-and attackers know it. As traditional EDR and SIEM tools struggle to keep up, identity-focused attacks are rising fast. In fact, 70% of breaches now start with stolen credentials, according to Verizon’s 2024 and 2025 DBIR reports. This calls for a smarter approach to identity security-one that unifies detection and response across cloud, on-prem, and everything in between.

That’s where Stellar Cyber’s Identity Threat Detection & Response (ITDR) steps in.

The Identity Security Crisis

Security teams are overwhelmed. Analysts are forced to pivot between fragmented consoles-EDR, SIEM, IAM, PAM, MFA-trying to connect dots while attackers slip through the cracks using:

Credential dumping
MFA fatigue
Lateral movement via hybrid networks
Living-off-the-land (LotL) tactics

Meanwhile, machine-to-machine identities, SaaS sprawl, and misconfigurations expand the threat surface. Traditional point tools aren’t enough.

Enter Stellar Cyber ITDR

Stellar Cyber puts identity at the center of security operations. It correlates Active Directory and Microsoft Entra ID signals with endpoint, cloud, and network telemetry-all in a single, AI-driven SecOps platform.

There’s no need for another agent or appliance. Lightweight, API-based connectors plug directly into existing infrastructure to deliver:

Real-time identity threat detection
Risk-based prioritization
Seamless response actions (e.g., disable accounts, isolate hosts, revoke sessions)
Unified dashboards with identity + XDR context

Key ITDR Capabilities

Real-Time Detection

UEBA flags suspicious behavior (MFA spray, geo anomalies, login spikes)
Tracks policy changes (GPO, MFA settings, login flows)
Detects identity-based data exfiltration and service account abuse

Unified XDR Context

Identity alerts tied to endpoint, network, and cloud data
Single-pane-of-glass investigations reduce alert fatigue

Automated Response

One-click actions: disable user, reset password, isolate system
Low-code playbook builder integrates with SOAR and ITSM platforms

Lateral Movement Containment

Detects and blocks Pass-the-Hash, golden ticket attacks
AD lockout, host isolation, and optional network segmentation

Identity Risk & Hygiene Monitoring

Continuously surfaces dormant accounts, overprivileged groups
Scores each identity's risk and links to specific assets

Threat Intelligence Enrichment

STIX/TAXII, MISP, and commercial feeds
Real-time IOC scoring (users, IPs, hashes)

Dashboards & Reporting

Compliance reports: PCI DSS, HIPAA, ISO, SOC 2
Executive scorecards: MTTR, remediated risks, identity trends

Flexible, Scalable, and Agentless

Works in SaaS, on-prem, or hybrid environments
No new agents required; deploy in under 1 hour

Machine & Non-Human Identity Protection

Monitors API keys, certificates, and machine-auth traffic
Detects anomalous machine-to-machine behavior Machine & Non-Human Identity Protection
Detects anomalous machine-to-machine behavior

MSSP-Ready Multi-Tenancy

Per-tenant isolation, RBAC, SLAs, reporting
Tenant-level playbooks and cross-tenant threat intel
