The most important thing I like about this is that it has an in-built firewall which helps to block all malicious attacks from harmful websites, emails or other applications as well! It's easy enough for anyone with basic knowledge of coding can use it without any issue at hand. Nothing much so far but if you are looking out something simple then go ahead otherwise there might be some issues here too!! We have used spherical defense api security while developing our android application where we were facing many problems regarding malware threats etc., now everything seems fine after using SPHERE DEFENSE APISECURITY.
