Transport Layer Security (TLS) 1.2 Compatibility

Transport Layer Security (TLS) is a cryptographic protocol that provides privacy and data integrity between two applications communicating over a network.  It is the most widely used security protocol in use today and is used by web browsers and other applications that require data to be securely exchanged over a network.  TLS is designed to prevent eavesdropping and tampering of data.  TLS replaced its predecessor, Secure Sockets Layer (SSL), in June of 2015 due to numerous security vulnerabilities in the SSL protocol.  The SSL protocol was also deprecated by the National Institute of Standards and Technology (NIST) in 2014 for the same reasons.  The Payment Card Industry Security Standards Council (PCI SSC) suggests organizations migrate from TLS 1.0 to TLS 1.1 or higher before June 30, 2018.  To comply with this movement towards a safer and more secure method of transmitting your data, First National Bank Weatherford requires all customers to access online systems using web browsers and applications that are TLS 1.2 compatible by default.  Due to this constraint, you may be required to upgrade you web browser prior to using our new systems.
