Marlins STCW Security courses have been approved by three maritime administrations (flag states): it is your responsibility to check which one you need before you buy. Your employer may have specific requirements.
Isle of Man approval is for our seafarers security courses, not for cruise ship courses. You can take the course and the test online, anywhere.
Liberia approval is for all our courses. You can take the course and the test online, anywhere.
UK MCA approval is for all our courses. You can take the course online, anywhere. However, you have to travel to a Marlins Approved Test Centre to take the assessment under exam conditions. You must enter your national ID details (passport or seaman's book) when you take the online course and you must take the same document to show at the Approved Test Centre.
