Are the Alison Cybersecurity Courses Really Free?
Alison states that its courses can be enrolled in, studied and completed for free. However, learners should distinguish between free course access and the official certificate or diploma.
For many Alison courses, the official certificate or diploma is an optional purchase.
Therefore, do not automatically assume that every Alison course advertised as a "free certificate course" includes a free downloadable certificate.
For example, Alison's current Ethical Hacker page states that learners can study and complete the course for free, while the official certificate is available as an optional credential.
This distinction is important when writing a CV or recommending courses to job seekers.
OpenLearn has some courses where a free Statement of Participation and/or free digital badge is explicitly available, such as its Introduction to Cyber Security course.
