Pros
Immense financial power Good investment in people Highly talented people (if you have the chance to work in one of the teams that actually functions properly) Good if you want a workplace to grow old in (should rather be a con as far as I am concerned but I see people are actively looking for such a a place)
Kontras
The following are based on my experience as part of the Security Organization: Unstable environment Success is highly dependent on the team you end up in The vast majority of employees are sub-par in knowledge (however there is some very strong talent to be found as well) Very poor company values (in practice) Very poor middle management Lack of planning and no consistent strategical/tactical approach Security maturity level could be objectively characterized as initial on the capability maturity model scheme Investment in security is lead by people who don't understand the security industry.
