Securing Online Transactions

Older internet browsers are becoming more of a risk than before. Issues with standard security built into browsers have forced the industry to migrate to newer versions. Keep your browser and mobile devices up to date to make sure you’re protected.


Transport Layer Security (TLS) is a protocol that ensures that a connection to a remote endpoint is securely encrypted in order to provide privacy and data integrity. TLS is a key component of internet browser security. TLS 1.2 is the most current version and is considered the most secure. TLS 1.0 and 1.1 are being discontinued due to security implications.
