The Fundamental Difference in Trust
Why modern security architects are replacing vendor-managed cloud keys with client-side zero-knowledge seals.
The Slack Reality: Unencrypted Channels, AI Scraping Policies & 90-Day Lockouts
In 2024, Slack updated its terms to use customer messages, shared images, and attachments to train machine learning models by default. Furthermore, Slack stores all team conversations in plaintext on Salesforce cloud servers, leaving them vulnerable to insider access, data leaks, and subpoenas. On the free tier, Slack hides message history after 90 days, holding institutional knowledge hostage.

History is retained permanently with pooled organizational storage without 90-day lockouts. Instant HD video huddles, collaborative docs, and canvas whiteboards are built right in.
