Do I need to do any certificates not just for cyber security but for other courses as well in UK/Ireland?

No, most master’s programs in Ireland and the UK do not require additional certificates beyond your bachelor’s degree.

- For cybersecurity, certifications like CompTIA Security+, CEH, or CISSP are not mandatory but can strengthen your application. - For other master’s programs, certificates are generally optional, though relevant ones may give you a competitive edge.
