Meeting security is the set of controls used to verify who is in a collaboration session and to reduce deception during calls. It covers practical measures such as identity checks, participant admission rules, warnings about suspicious accounts or media, recording permissions, and tools that help spot synthetic audio or video. The goal is to make it harder for an attacker to impersonate a coworker, vendor, or executive.
This matters because video meetings often carry real business authority: people approve payments, share sensitive data, and grant access based on what they see and hear. Attackers abuse that trust with social engineering, fake accounts, and deepfakes that make a caller seem legitimate. Defenses turn the meeting itself into a checkpoint, giving users time to verify requests, compare identities, and refuse rushed actions. Strong meeting security does not eliminate fraud, but it can expose warning signs early enough to stop a successful impersonation.
