There are probably others. These could be useful niche products for use in limited situations. Any of the products discussed should not be used for primary encryption. If they wanted to distribute data, they would burn a CD with the information encrypted and include in the CD the decryption program.
Information is only as valuable as it is kept secret.
Most systems are not designed and implemented in concert with cryptographers, but by engineers who thought of cryptography as just another component. You can't make systems secure by tacking on cryptography as an afterthought. You have to know what you are doing every step of the way, from conception through installation. After all, weak cryptography looks the same on the shelf as strong cryptography. Two e-mail encryption products may have almost the same user interface, yet one is secure while the other permits eavesdropping.
