Making Email Encryption Easier

Email encryption purchases often stall when protection depends on users changing how they work. While the security department wants to go for end-to-end security, the applications are still sending out the messages automatically due to ticketing and collaboration applications. In case encryption comes into play after the message is sent from the application, then the sensitive data will pass through an unnecessary exposure point. It all depends on where the encryption will take place and how much infrastructure will have to be changed. Application-level integration is especially crucial when emails are automatically created rather than being composed manually. Software capable of recognising the recipient and obtaining the correct key can encrypt an email message even before it hits the mail server. Potential customers need to find out whether the software is capable of discerning between workflows needing encryption and those that do not. It might be necessary to block a message if encryption is impossible in cases of very confidential workflows; others could be allowed to flow without any trouble. This flexibility of approach is much better than applying a single strategy regardless of the content of an email message. Infrastructure fit may even be the determining factor in whether or not a security project proceeds at all. Changing out a mail server or altering client-side software represents a cost and implementation burden that may override the technical value added. An infrastructure fit that enables use within an existing mail environment allows the security organisation the ability to deliver protection without overhauling the entire infrastructure. The need for phased rollouts is critical when certain users or applications can support end-to-end encryption, but others cannot. “Savignano’s rules can determine when encryption is required and block transmission when protection cannot be applied.” Protection of stored email deserves the same attention as transmission. Mail servers often retain large volumes of business correspondence, leaving accumulated messages exposed if an attacker gains access to the environment. Buyers should look at whether encryption applies only while messages move between parties or also to persistent mail stored on the server. The distinction affects the blast radius of a server compromise and should be clear before deployment. Security maintenance is another purchasing requirement that is easy to underweight. Encryption software itself becomes part of the attack surface, so buyers need evidence of ongoing testing and external review. A clear response process for discovered issues should accompany both. They should also examine how the provider tracks changes in cryptography and whether its architecture can support newer algorithms as requirements evolve. Transparent licensing and feature definitions help procurement teams compare scope without discovering key limitations after implementation. Savignano’s S/Notify integrates directly with Atlassian products and encrypts outbound messages before they reach the mail server, while also supporting incoming encrypted mail in Jira-based workflows. Its rules can determine when encryption is required and block transmission when protection cannot be applied. Copies can also be routed for archiving when needed. Uptrust extends that model beyond Atlassian through a gateway that can work with existing mail infrastructure and support phased adoption. The company also describes continued security testing and support for evolving cryptographic methods. Buyers running sensitive application-driven email flows, especially those that need stronger protection without replacing their current mail environment, have the clearest reason to evaluate Savignano. ...Read more
