More time posting than coding
A lot of these 'education providers' went bust during the beginnings of the last recession.
Why would you pay or engage a company to teach you something you can learn yourself using the same course materials from the relevant professional institutions?
Use CEH (Certified Ethical Hacker) and adapt your coding skills in order to enter the market. Do you think a future employer wants to see that you studied at some random Trump-University style noname institute? No, they want the core certifications.
If you're struggling for cash now and every pound is precious then there are plenty of library books out there and other free resources to achieve enough information in order to study these topics and resources. It's good to aim for general information and not provider specific. CEH is more valuable than a Microsoft published azure security course, as you can read the material of the latter and understand it without passing the exam.
Good luck. Use your head and don't rely on anybody else to teach you anything, teach yourself and save the cash.
