Patchman is designed to fix security vulnerabilities without touching anything else on your site - here is why that matters.

## How Patchman patches your site

Unlike a full application update, Patchman applies surgical fixes only to the specific lines of code that contain a known vulnerability. Everything else - your plugins, themes, configuration, and content - is left exactly as it is.

Full application updates, by contrast, replace large amounts of code at once. This can break plugins or themes that depend on a particular version of the application, which is a common cause of sites going down after an update.

:::info
Because Patchman changes only the vulnerable code and nothing more, it carries a much lower risk of disrupting your site than a full upgrade would.
:::

## What this means for you

- Your site continues to work normally after a Patchman patch is applied.
- Plugins and themes that rely on a specific application version are not affected.
- You get the security benefit of the fix without the compatibility risks of a full update.
