It totally depends on how much data you have and what you're looking to encrypt. If a person were interested in encrypting as few as 100 emails, the full encryption process could take days or weeks with significant upfront costs (software, hardware). For an organization storing large quantities of data, the investment would be far higher for instant encryption. If someone had one terabyte of data, they might pay upwards of five figures to put it safely into encrypted storage formats. Trying to protect personal information from hackers should always start with a basic awareness campaign that leads people toward the goal we all share: scrambling any data we post online so people we never meet can't just grab it and use it against us!
