There are so many different fields in Cybersecurity, this would be difficult to answer. It ranges from pen testing to compliance and everything else in the middle.
In my opinion, the demand for CS (security) jobs will continue to surge forward as we move into a digital world, comprising of smart devices, vehicles etc. Jobs are generally stable in terms of income, employment and job security because of the lack of foreigners fighting for your spot.
However, CS and IT are seen as massive cost-center since their impact on a business is hard to measure. If you are in it for the money, don't expect to become rich unless you are in a profit-center or in sales. Also, look at what happened to life science graduates when the goverment hyped it up.
