Slack revolutionized workplace communication but was built for convenience, not security. Every message on Slack is stored in plaintext on their servers. For businesses handling sensitive information, this creates unacceptable risk.

Slack stores all messages, files, and shared content in plaintext on its servers. Slack employees, workspace admins on paid plans, and anyone who compromises Slack's infrastructure can access your business conversations. WeTalkin encrypts everything end-to-end—no one except the intended recipients can read your messages.
Business conversations on Slack contain trade secrets, financial projections, client information, HR discussions, and strategic plans. All of this sits in readable form on Slack's servers. A single Slack breach could expose your most sensitive business data. WeTalkin's zero-knowledge encryption eliminates this risk entirely.
For regulated industries (healthcare, finance, legal), Slack's plaintext storage creates compliance challenges. WeTalkin's end-to-end encryption satisfies the encryption requirements of HIPAA, GDPR, and financial regulations by design. The data is protected technically, not just by policy.
Slack's extensive integration ecosystem is a feature but also a privacy risk—each integration can access channel data. WeTalkin takes a more selective approach to integrations, ensuring that third-party tools cannot compromise the end-to-end encryption of your communications.
For general team coordination where convenience outweighs confidentiality, Slack works well. For sensitive business communication—executive discussions, legal matters, M&A, HR issues—WeTalkin's encryption is essential. Many organizations use WeTalkin alongside Slack for their most confidential channels.
Make the switch to zero-knowledge privacy. No phone number. No metadata.
Yes. Slack stores all messages in plaintext and can access them. On paid plans, workspace owners can also export all messages including DMs. Slack has stated they may use customer data to improve their services. For confidential business communication, use WeTalkin.
WeTalkin can replace Slack for secure team messaging with workspaces, channels, and file sharing. However, Slack's extensive integration ecosystem and workflow automation tools go beyond messaging. Many teams use WeTalkin for sensitive conversations and Slack for general coordination.
WeTalkin Pro is $15.99/mo per user with full E2EE and zero-knowledge architecture. Slack Pro is $8.75/mo but with no encryption. For the security WeTalkin provides, the premium reflects the engineering investment in zero-knowledge encryption infrastructure.
