One of the key benefits of a free security course is that it is a cost-effective means to assess your interest in a topic before you make a financial commitment.
It’s important to keep up to date with advances in security, whether you are technical or GRC focused. The ability to demonstrate an enterprise wide appreciation of security will increase your chances in interviews and increase career progression opportunities.
I have comprised 10 free Cyber Security courses for your perusal. They are varied: some targeted at a technical audience, whilst others are suited to those who require a greater understanding of security – I have also thrown in a few targeted at experienced security practitioners.
The courses are in no particular graded order!
