As Slack  makes its way deeper into the enterprise, it needs to layer on more sophisticated security measures like the encryption key management feature it released last year. Today, the company published a blog post outlining its latest security strategy, and while it still doesn’t include end-to-end encryption of Slack messaging, it is a big step forward.

For many companies, there is a minimum level of security they will require before they use a tool like Slack company-wide, and this is particularly true for regulated industries. Slack is trying to answer some of these concerns with today’s post.

As for end-to-end (E2E) encryption, Slack believes it would adversely affect the user experience and says there hasn’t been a lot of customer demand for it so far. “If we were to add E2E encryption, it would result in limited functionality in Slack. With EKM (encryption key management), you gain cryptographic controls, providing visibility and opportunity for key revocation with granularity, control and no sacrifice to user experience,” a Slack spokesperson told TechCrunch.

Today, the company provides the ability for admins to require Touch ID or Face ID or to enter a passcode on a mobile device. In addition, if a user reports a device stolen, admins can wipe Slack conversations remotely, although this is currently only available through an API.
