A Wi-Fi network sweep is a technical review of a home or office network. It identifies every connected device, evaluates access controls and account credentials, and checks for unauthorized access or data transmission. Routers, cameras, microphones, and other connected devices can retain credentials and cloud account links that remain valid until they are changed.
We inventory the devices connected to your network, secure access so that only authorized users have control, and recommend updated equipment where appropriate.
Indicators of Unauthorized Access
- Connected devices transmit data to destinations you cannot identify.
- Unrecognized devices appear in the router client list or in a network scan.
- Cameras, doorbells, speakers, or thermostats remain linked to accounts you do not control.
- Wi-Fi, router, or internet service account credentials have not been changed since the devices were first configured.
- Router, camera, or smart home device settings change without administrator input.
What We Do
Sweep the Network
We inventory every device on the network, wired and wireless, and identify the make, model, and function of each. Unrecognized devices, including cameras, microphones, and smart plugs, are documented.
Reset and Harden
We reset credentials and harden the configuration: new network name and passphrase, new router administrator credentials, updated firmware, remote management disabled, and a review of the internet service, router, and smart home accounts tied to the network. Shared cloud accounts for cameras and doorbells are a common point of unauthorized access, so we review those as well.
Upgrade Your Equipment
Older routers often lack current security updates. Where appropriate, we recommend and configure a current Wi-Fi 6, 6E, or 7 router or mesh system, with an isolated guest network for visitors and smart devices.
Check Beyond the Wi-Fi
Some tracking and listening devices use cellular or Bluetooth connections instead of Wi-Fi. A full technical surveillance countermeasures (TSCM) sweep covers rooms, vehicles, phones, and computers.
Before You Reset Anything
If the findings may be used in a legal matter, contact us before making changes. Resetting a router or removing a device can erase logs and other evidence. We document and preserve findings and can coordinate with your attorney. We work only on networks, devices, and accounts that you own or are authorized to manage.
California law generally prohibits recording a confidential communication without the consent of all parties (Penal Code section 632).
If you believe you are in immediate danger, call 911. If you suspect the network is being monitored, contact us from a device and network you trust.
