54% of Enterprises Have Had an AI Agent Security Incident, Most Still Share Credentials Across Agents

A new VentureBeat report reveals that 54% of enterprises have already experienced a security incident involving an AI agent, yet a majority of organizations still allow agents to share credentials — a practice that dramatically expands blast radius when any single agent is compromised. This is not a theoretical risk: more than half of surveyed organizations have already been hit, making agent security an active operational concern rather than a future-state problem. The credential-sharing issue is particularly acute because agents operating with shared or over-permissioned identities can pivot laterally across systems in ways that traditional security models weren't designed to catch. For developers deploying agents in enterprise environments, this is a direct call to implement per-agent credential scoping, least-privilege access, and audit logging before going to production. The finding reinforces that agent security architecture needs to be a first-class design concern from the start, not a retrofit.
