By just one click on your dashboard you can generate a single fix for vulnerability or a bulk fix for all the vulnerabilities that have a fix.
The pullrequest will have all the info about changes done and why we changed those files. All you have to do is review & merge.
We try to limit the fix to the required changes needed to fix the vulnerability without affecting your current code flow and compatibility.
If there is major change or major dependency update you will be notified in the pullrequest to review it manually to make sure nothing break.
