Microsoft Teams is set to significantly bolster user security with the introduction of AI-powered threat detection. This advanced system will analyze conversation context to proactively identify phishing, social engineering, and impersonation attempts within messages.
The AI-driven capability is designed to detect suspicious behavior that may not rely on traditional indicators like malicious links. Its rollout is planned for November 2026, making it available to all Microsoft Teams users worldwide.
