Pros

+ Best tech and most robust security offerings on the market - by far! + Great onboarding and learning potential + Customer value focus

Cons

- Demanding work and can be challenging to keep track of everything - Company still needs to iron out some processes and there's far too much bureaucracy getting certain things done internally which can slow things down too much (but we tend to always manage)
