js/php/py network security monitoring?

Question

Computer networks

Guys, there are services that offer to check your network for security.
And give out such statistics.

spoiler

And suppose we want to do the same for our site, why should we push off and where or how to get or write such functionality?
It’s just that I’ve never come across this, but they asked if it’s possible to do something in our company?
I will not give a link to the service, no matter what it is, the main thing is the meaning of the report.

Answer 1

Guys, there are services that offer to check your network for security.

1. You can only check the network for security from inside this network!
2. Check the code for safety - only by giving the source code to a professional programmer who understands the whole process of data movement.
3. Check the server - only giving access to the security officer.
Also, there are utilities that scan the server for known vulnerabilities and issue a report also from inside the corporate network.
There can be no web services!
Only an adequate approach to the problem and setting up a firewall.

Answer 2

There is no sense in such reports.
This section does not check network security.
