Zero Trust for Non-Human Identities

A swarm of service accounts moved through the system, unseen, unchecked. Each one could be the next breach.

Non-human identities are now the dominant actors inside modern infrastructure. APIs, bots, workloads, and automation scripts run at speeds no human can match. They call endpoints, trigger pipelines, and exchange secrets without pause. Each identity carries permissions. Each permission is a potential exploit.

Zero Trust is no longer optional for these identities. Traditional perimeter controls fail when cloud services, CI/CD systems, and microservices talk across networks you don’t own. A single compromised token can give attackers lateral movement through dozens of systems. The principle is simple: never trust, always verify—especially for non-human entities.

To secure non-human identities in a Zero Trust model, start with strict authentication. Every API call, script execution, or service boot must prove its identity at runtime. Rotate keys and tokens frequently. Use short-lived credentials tied to specific scopes. Enforce mutual TLS between services.

Authorization must be fine-grained. Separate roles for different service accounts. Lock down permissions to the exact actions required. Monitor behavior in real time, and flag anomalies where an identity moves outside its normal patterns.

Visibility is critical. Inventory all non-human identities across cloud, on-prem, and hybrid systems. Track their lifecycle. Remove stale accounts. Connect logs from authentication, authorization, and workload execution for a unified view.

Automation makes Zero Trust scalable. Policy as code ensures consistent enforcement across environments. Integrate identity checks into every deployment pipeline so infrastructure changes never bypass security.

Attackers know service accounts often have more power than user accounts. They target tokens in config files, CI secrets, and cloud metadata. With Zero Trust for non-human identities, the stolen token is useless without continuous verification.

The pressure to secure at machine speed is real. Building this system without complex tooling is hard. hoop.dev lets you apply Zero Trust controls to every non-human identity with policy enforcement, real-time monitoring, and instant deployment. See it live in minutes at hoop.dev.
