Late one evening I went on a deep dive to find some online certifications that were relatively cheap, had a decent course rating to bolster my CV a little, here’s some courses I completed as most of the security knowledge I have gained over the years has been self taught and I’m told these pieces of paper (pdf’s or images) could help!
Web App Security Fundamentals Certificate
Counterveillance 101 Certificate
IDS / IPS Certificate
Cryptography Certificate
