Normal email is not secure! With the thousands of malevolent hackers around the world and the rise of widespread government monitoring programs, a secure email service is needed by many individuals, corporations, and others.
A number of companies offer secure versions of email services for additional fees, each with its own advantages and disadvantages. The one drawback of all of them is that the user is dependent on the company that writes the software and provides the service. Do you trust the company’s security? Is their software really secure?
I suspect the answer is “Yes” to both of those questions although I do not know of any method of proving it. Without such assurance, a provable secure alternative that does not depend on any company or any other person for security is a very attractive offering.
One alternative is to use a service that does not depend on email companies, does not use the normal email networks, and uses open source software that is available for security examinations by anyone. It is also immune to most big tech companies’ outages that disrupt email or other messaging services due to software bugs or network failures. In addition, it is invisible to the prying eyes of hackers or government spies. Finally, it appears to be 100% legal, at least for now.
