The best part about cryptalabs, in my opinion at least was their customer support team - they were always there for me when needed (even after office hours). Their business model has changed recently so it became harder/more expensive than before but still worth taking into consideration if you're looking forward towards building your own IoT product with security as one major priority! It's not easy nowadays finding such talented engineers who are also passionate enough regarding cybersecurity issues which we all know can be very complicated especially from technical side perspective; however this does NOT mean crypto solutions cannot help solving some problems out here & make things more convenient overall by combining them together while keeping user privacy intact!!
