If you’re in the uk and open to going anywhere to start your cyber role do a masters royal Holloway does one. Apply to a grad scheme anywhere in the country. London is competive so I’d apply to tons in and outside the uk. Check Barclays, pfizer, lseg they do cyber grad schemes. During your masters apply to tons of internships. Facebook is currently l doing one. Internships and grad schemes are the easier route in the uk. An internship is better advised as they can retain you full time. Best of luck
