Think about all of the databases that store private information like credit card numbers and social security info. Our personal information is literally at the mercy of some random security/network engineer. How secure are these servers? Can we trust that our private information is actually secure?
This is where Very Good Security comes in. They essentially redact and tokenize sensitive data and return a hashed form to the data requestor. A credit card number under VGS is no longer stored as text, but stored as a random string of characters. This increases the security of a database by requiring a 3rd party to decode the random string of characters at the request of an operator (like a credit card company).
