Cyphlens CypherMessaging provides message-level encryption for Slack and Microsoft Teams to protect sensitive conversations within existing collaboration platforms. The solution encrypts messages and images before they enter chat channels, ensuring content remains protected against unauthorized access, screenshots, forwarding, and exports. The platform implements identity-bound access controls that restrict message decryption to verified recipients only. Messages remain encrypted even when forwarded to email or SMS, and can only be viewed by intended recipients. Access permissions persist across platforms and applications. Time-based controls allow messages to expire after a set date or burn after first read. The system blocks screenshots and prevents AI bots, plugins, and third-party integrations from accessing encrypted content. An audit dashboard tracks who viewed each message and when. The solution uses quantum-resistant encryption and provides SOC 2-compliant controls. It deploys directly inside Slack and Teams without requiring users to switch platforms or change workflows. The encryption prevents LLM ingestion of sensitive data shared in messaging platforms. Use cases include sharing sensitive credentials, API keys, passwords, financial data, contracts, and confidential documents within team chat environments. The platform aligns with organizational security policies and compliance requirements.
