Devin Security 2.0 adds frontier-model scanning and autonomous remediation

Cognition announced a major Devin Security upgrade combining frontier cyber-model scans, environment-aware prioritization, and autonomous remediation that turns findings into pull requests. It also announced hundreds of millions of dollars in Devin credits to help enterprises find and fix critical vulnerabilities.

Why it matters: The upgrade links vulnerability discovery to proposed code changes, potentially reducing the manual work between security findings and remediation.

Releases

GitHub Copilot assisted permissions reach general availability across CLI, app and VS Code

Assisted permissions are now generally available in GitHub Copilot CLI, the Copilot app, and Visual Studio Code. The feature applies when Copilot requests permission for actions such as running commands or accessing file-system paths.

Why it matters: Teams using these Copilot interfaces can now incorporate the generally available feature into their agent permission workflows.

In practice

OpenAI reports Codex Ultrafast cuts incident investigation from hours to minutes

OpenAI described engineers using Codex Ultrafast to investigate incidents in minutes rather than hours. The account also covers security analysis, code refactoring, and daily engineering workflows.

Why it matters: The account offers a concrete operational use case for coding agents beyond writing code, though the reported gains come from OpenAI itself.
