The ability of securezip for encrypting all your files at once with one click was very helpful in my work as it saved me time from copying/pasting multiple times! It's quite expensive compared other software but I guess this comes along when you have many users using their own copies (which can be easily copied).
But if used properly then there won't really anything wrong about its price or lack thereof because security should always come first than money anyway!! So far nothing bad has been said by anyone who uses our office documents which are encrypted so we don’t see any issues yet since they aren;' t able get into them without proper authentication procedures done before hand like us having 2 factor authentications etc.
