IonWarpTry for free secret scanning
A pattern scanner finds a string shaped like a key. IonWarp reads what the change does with it: a credential copied into a prompt for an outside model, a key bundled into client code, a token written to a log. It reviews the pull request before the merge, beside Code Review, and hands the fix to your coding agent.
A new pass read a repository's deploy config files into a prompt for an outside model and redacted only the answer, so any credential in those files went to the model provider. A pattern scanner has no rule for that; the fix moved redaction before the prompt.
A deploy workflow put a caller's `sha` input into a shell command unquoted, in a step that holds the deploy keys. The finding showed why the script's own check came too late: the shell expands the input first.
A path guard collapsed `..` before it resolved symlinks, so a symlink could read files outside the checkout. Security Review named the path and how to close it.
IonWarp reviews pull requests, not git history, and it does not block a push. Keep a scanner that blocks commits with known key formats; IonWarp catches the leaks that do not look like a key.
Every finding carries a fix prompt for Claude Code, Cursor or Codex. The GitHub App is read-only, so it never pushes: your agent pushes the fix, and IonWarp re-reviews and strikes the finding through as Autofixed, or keeps it open.
