Encryption should be applied to any sensitive information transmitted by email and, when possible, company policy for encryption should be enforced automatically by technological means. Even though employees can be trained to operate in-house encryption solutions, there is always a chance of user errors that can leave a company vulnerable.
To avoid this problem, many companies choose a hosted encryption service. With a hosted service, there is no need to purchase, implement or maintain software or hardware. Deployment is quick and easy and there are no updates or upgrades to install. A hosted service provides a global network and a lower total cost of ownership.
