A question I get asked a fair bit! There are many publications out there, each with their own merits – just because I regularly read 2 in particular isn’t in any way a slight on the others. It that I find these two magazines keep me well informed. I do a lot of other research and reading but still find Professional Security Magazine https://www.professionalsecurity.co.uk/ and City Security Magazine https://citysecuritymagazine.com/ extremely useful.
I encourage you to check out both magazines for yourself.
Professional Security Magazine is an amazing publication, it is jam packed with information, connections, news and views. It is a veritable encyclopaedia of security industry knowledge.
City Security Magazine provides articles subdivided by niche that provide good quality information. A must read if you work in the security industry frontline!
