Synonym discussion
Sense: adjective/1
These three words all describe something that can be protected, but they differ in how. 'Fortifiable' is the most specific: it means a place can be made stronger by adding walls, banks, or other defences, so it leans toward military or physical building work. 'Defensible' is more common and wider; it simply means a position is easy to hold against attack, often because of its natural shape, with or without extra building. 'Securable' is the broadest and least military: a door, a network, or a building is securable if you can make it safe by any means, such as locks or guards. Compare: a steep hill is naturally defensible; that same hill becomes fortifiable once you decide walls could be built on it; a warehouse with good locks is simply securable.

Etymology
Built from the verb 'fortify' plus '-able', a common ending that turns a verb into an adjective meaning 'able to be done'. 'Fortify' came into English through Old French from Latin 'fortis', meaning 'strong', combined with a root meaning 'to make'. So the word literally points to something that can be 'made strong'.
