For as long as we’ve been able to send messages over email, some people have done whatever they can to get an unauthorized peek. Whether it’s for espionage, blackmail, identity theft or some other criminal purpose, an email privacy breach can spell disaster for organizations and private individuals. As such, we need to do what we can to protect the data we send over email.
Encryption should be thought of as an absolute must.
Major email providers today understand that emails need encryption, and most offer basic protection by encrypting emails at rest. But do you need to go a step further? That is, do you need to encrypt end-to-end? Or is it more effort than it’s worth?
Let’s take a quick look at the major pros and cons of end-to-end solutions.
End-to-end encryption is the continuous protection of data throughout processing, from its origin point to its destination. This has been an attractive solution for organizations that must go beyond basic protections, precisely because it’s so thorough in scope. It also is seen as a viable option because it plugs easily into existing architectures. Alternative solutions, such as tokenization, might take more configuration to operationalize.
However, end-to-end encryption is not without its drawbacks. For one, the solution can be unwieldy to manage, requiring ongoing maintenance to keep it running properly. And one weak link in the encryption flow can undermine the whole solution. This means end-to-end encryption can wind up being a relatively expensive proposition.
Not all encryption solutions are built the same, and experts are constantly looking for ways to make them more streamlined and user-friendly.
For instance, ProtonMail, one of the leading email encryption solutions, leverages both public-key cryptography and symmetric encryption protocols for a multi-faceted but simple approach. The open-source Signal Protocol, developed by Open Whisper Systems, has enabled its developer to power a secure messaging app growing in popularity around the globe. It also is available for organizations to take up in the protection of their own communications.
Provided an organization can find the right partner, end-to-end encryption can certainly be worth the time and cost of operationalizing. Lunarline can help your team overcome the challenges and reap the rewards. For more information on how we can help, contact us today.
