Systron uses Secure Sockets Layer (SSL) for secure transmissions to protect your information on the Internet:. SSL applies encryption between two communicating applications, such as your PC and our web server. When your data is transmitted over the Internet under SSL, everything you send to us and all information you receive back is encrypted. This means that no one on the Internet could read our transmissions. If anyone were to capture the data we sent back and forth it would be uninterruptible . We use 128-bit encryption, the highest level generally available today.
