I hope that helps.

\ As a large-scale enterprise, you are highly vulnerable.

\ It is not easy to secure every point of access when you employ thousands of employees.

\ My recommendation is: go for the external firms if your budget can afford it.

\ Otherwise - train your own group, in station.

\ It often helps to have your own people retrained in cybersecurity by external training firms.

\ And those exist too!

\ Outsourcing could cost 50,000 USD a month.

\ But if you have the money, it could be the best investment of your entire enterprise.

\ All the best!
