Question

I have some credential requirements for my modules in security.yml.
How can i run a method before this checking is done? Is there any events for doing this?

Filters might be what you need.
Filters are run first every time your application runs.

Just add a filter in the apps/(front|back)end/config/filters.yml file:

myFilter:
  class: myFilter

And create the class in lib/:

class myFilter extends sfFilter
{
  public function execute($filterChain)
  {
    // write your code here...

    // execute the next filter
    $filterChain->execute();
  }
}
