A security sweep is a deliberate search of a sensitive area for unauthorized devices, hidden cameras, recording tools, tampering, or other signs that someone has interfered with the space. Unlike network monitoring, it focuses on the physical environment: meeting rooms, executive offices, lab spaces, and storage areas where confidential work happens.
Security sweeps matter because many attacks begin with physical access rather than malware. A small device can capture conversations, relay audio, or create a surveillance foothold without triggering digital defenses. In practice, sweeps may be done before high-level meetings, after a staffing change, or when a room has had unusual access. They are part of a broader physical-security program that includes access control, visitor handling, inspection routines, and tamper checks. Used regularly, sweeps help detect covert recording and other insider-risk activity before sensitive information is exposed.
