What to look for when analyzing a site on Codeigniter?

Question

CodeIgniter

Hi people. Then people contacted me, asking me to conduct a comprehensive audit of the site on Codeigniter. Who works with him, are there any framework-specific things that you should pay special attention to?
Well, in general, a few words about how it is with security, speed, extensibility and ease of use, it would be great.
I myself have not come across it, I use Symfony2 more and more. I looked, it looks good, but on off-sites everything is always beautiful.
Thanks in advance!

Answer 1

How can you audit a project without knowing the framework?
How do you determine if an aspect is part of the framework's conventions or a bug in the project?

Answer 2

What the fuck is the difference on what framework the site is? You need a site audit, so look at the code in the application folder.
