OpenAI strengthens Enterprise Security with Lockdown Mode

OpenAI introduced Lockdown Mode for high-security users and Elevated Risk labels across ChatGPT, Atlas, and Codex, reducing prompt injection threats, limiting tool access, and improving oversight.

OpenAI launched Lockdown Mode, an optional advanced security setting for executives and security teams needing stronger protection against prompt injection and data exfiltration attacks.

In this mode, ChatGPT restricts external tool use, limits browsing to cached content, and disables higher-risk capabilities when deterministic safety guarantees are not possible. Alongside this, OpenAI added Elevated Risk labels across ChatGPT, ChatGPT Atlas, and Codex to clearly flag features that may introduce additional security concerns, such as granting network access.

These protections build on enterprise controls like audit logs, role-based access, and monitoring, with consumer rollout planned soon.
