Hi all,
This is my first post so apologies in advance

I'm on an industrial placement this year working as a test environment support analyst but I want to get into network security as a career as fast as possible. I have a basic knowledge of networks and security engineering from university/self study but nowhere near enough to consider applying for jobs.
It seems gaining certificates is to way to go but N+ and S+ are pretty expensive and i don't want to spend money on a certificate that i don't need to get into the security industry.
Can you beautifully insightful people give me some advice on the best route to take to get into the security industry (more specifically penetration testing) seeing as I graduate in around a year and a half ?
