Secure Sockets Layer (SSL) is a protocol for enabling data encryption on the intranet and for helping web site users confirm the owner of the web site.
Encryption is a mathematical process of coding and decoding information. The number of bits (40-bit, 56-bit, 128-bit, 256-bit) tells you the size of the key. Like a longer password, a larger key has more possible combinations.
Browser ubiquity is a key element when choosing an SSL provider. Positive SSL is trusted by 99.9% of the current Internet population. This is equivalent to more expensive Certificates from Thawte.
As a valued SSL customer, you receive first class technical support for any issues or questions you may have during any part of the application, installation or life-cycle of your SSL Certificate.
