I've been in Cyber Security for almost 20 years now. The field is saturated, but not so much at entry level/analyst levels although those roles have become much more competitive in the states. When I used to hire that level we'd typically recruit from technology roles, particularly network engineers. Some certifications out there for that like CompTIA A+, Network+ and Security+.
It's been a while ago now but my route to cyber was after working in product roles. Led me to application security then just about every other security domain.
Like every tech field, AI is having its impact. Much more can be automated in triage but you still need a human to sort through things and deal with people and problems.
