Why AI Agents Leak Secrets (And How to Stop It)
The 5 most common ways AI agents leak secrets — from .env files on disk to context window exposure — and concrete mitigations for each vector.
Blind Mode Explained: Secrets Your AI Agent Never Sees
How KeyZero's blind mode uses a local MITM proxy to give AI agents opaque tokens instead of real secrets, swapping credentials at the network edge.
Runtime Secret Resolution vs. Static .env Files
A side-by-side comparison of static .env files and runtime secret resolution covering security, rotation, auditability, and developer experience.

A factual comparison of KeyZero, HashiCorp Vault, AWS Secrets Manager, Doppler, and Infisical for managing secrets in AI agent workloads.
Securing MCP Servers and AI Tool Chains with KeyZero
How to use KeyZero to manage secrets for MCP servers, prevent credential leakage in tool responses, and secure AI agent tool chains.
Policy-Based Access Control for Machine Identities
How KeyZero's PDP server uses JWT verification and CEL policy evaluation to enforce fine-grained access control for AI agents, CI runners, and service workloads
From Hardcoded Secrets to Zero-Knowledge: A Migration Path
A step-by-step guide to migrating from hardcoded secrets to vault-backed, policy-controlled secret resolution with KeyZero
The Secret Sprawl Problem in AI-Native Development
How AI-powered development multiplies credential exposure through code generation, agent tool calls, and context windows -- and what zero-trust secret management looks like
How KeyZero's Architecture Keeps Secrets Off Disk
How KeyZero keeps secrets off disk: the blind-mode MITM proxy, CEL policy decision point, multi-backend provider abstraction, and shell hooks
Five Patterns for Secret-Safe AI Agent Deployments
