As non-human identities (NHIs)—including service accounts, containers, APIs, and automation scripts—continue to outnumber human identities in modern digital infrastructures, organizations face an urgent need to secure these identities across complex hybrid and cloud-native environments.

TrustFour introduces a 3-layer NHI Security Framework that combines compliance enforcement, real-time visibility, and proactive threat defense to dramatically reduce the attack surface and improve operational resilience.

Key Highlights:

Layer 1: Posture Management – Compliance Hygiene, Crypto Agility, and Cybersecurity Maturity

• Compliance Hygiene: Enforces adherence to identity and encryption standards (e.g. NIST, OWASP) to reduce regulatory risk.

• Crypto Agility: Supports seamless cryptographic upgrades to defend against deprecated algorithms and threats.

• Cybersecurity Maturity Metrics: Enables continuous improvement with benchmarks and posture scoring for NHI environments.

Layer 2: Visibility – Discovery, Reporting, and Workload Authorization Mapping

• NHI Discovery & Reporting: Automatically identifies active NHIs and flags shadow or unauthorized identities.

• Workload Authorization Maps: Visualizes the “who talks to what” across the environment, exposing rogue lateral communication.

• Audit-Ready Reports: Ensures accurate NHI inventory and historical tracking to meet governance requirements.

Layer 3: Attack Surface Management – Auto mTLS, Advanced Telemetry, and Proactive Defense

• Auto-mTLS: Encrypts and authenticates machine-to-machine traffic by default, preventing lateral movement.

• Advanced Telemetry: Leverages honeypots, tripwires, and data-in-transit monitoring for behavioral detection.

• AI-Powered Threat Detection: Continuously analyzes anomalies to surface high-risk patterns before they escalate.

Why It Matters

This layered approach goes beyond traditional IAM or PAM for machines. TrustFour ensures every NHI is:

• Properly configured,

• Continuously monitored,

• and actively protected in real time.

With AI, auto-mTLS, and zero-trust workload isolation, organizations gain both visibility and control across all machine-to-machine traffic—making this framework a cornerstone for any modern NHI security program.

Bottom Line

TrustFour’s 3-layer NHI security model offers a forward-thinking, compliance-driven, and threat-aware strategy to help organizations govern, monitor, and secure their exploding NHI footprint—before it becomes a vulnerability.
