If you're doing $70/hr in the UK at CISO level you're way under some of your competitors.
Heck Pentesters charge more than that and they're 50%+ cheaper in the UK than the US.
My hourly rate in the UK as an Big-4 Infosec consultant 15+ years ago was way more than that and I wasn't doing CISO work. Partners (who were the kind of people doing that kind of work) were 10x your rate back then.
It's actually a similar price in Germany. There are higher paying jobs in Berlin, but in general it's not unusual to have this price in Europe. France and Spain is even lower.
