Teams Gets a New Defense Against Imposter Calls
Microsoft is launching a groundbreaking security feature within Teams calls designed to immediately alert users to potential social engineering attempts by external callers posing as trusted organizations. The new “Brand Impersonation Protection” will proactively scan incoming VoIP calls from first-time external contacts, displaying high-risk call warnings before the conversation begins.

Protecting Users from Social Engineering Threats
The core purpose of this new Teams security feature is to mitigate the risk of social engineering attacks, a tactic frequently used by scammers to steal sensitive information or funds by impersonating legitimate businesses or government agencies. By identifying suspicious patterns during initial calls, Microsoft aims to prevent users from falling victim to these deceptive strategies.

Automatic Protection, User Control
The “Brand Impersonation Protection” feature activates automatically, without requiring any administrative action, providing immediate defense. Users retain the option to accept, block, or end flagged calls. However, the warning signals will persist during the call if suspicious activity continues, highlighting the ongoing vigilance needed for maximum protection.

Microsoft’s Commitment to Secure Collaboration
This new Teams security feature aligns with Microsoft’s broader investments in caller identity protection and secure collaboration. The implementation showcases Microsoft’s continuous efforts to safeguard its users and bolster the overall security of its Microsoft 365 suite.

Insights from CISOs Fuel Strategic Spending
Microsoft’s security initiatives are informed by critical insights gathered from over 300 CISOs and security leaders, as detailed in the 2026 CISO Budget Benchmark report. This report provides valuable benchmarks for organizations to understand and adapt to emerging trends and priorities in cybersecurity investment.
