Wireless Penetration Testing

What is a wireless penetration test?

A wireless penetration test is a hands-on test of your Wi-Fi. We look at encryption and authentication, how well your guest network stays separate from your corporate network, and whether someone could stand up a fake access point that your devices will happily join. Then we try to break in, because the question that matters is simple: does your Wi-Fi give an outsider a way onto your internal network?

Why does Wi-Fi need its own test?

Your wireless network doesn't stop at your walls. Anyone within range, sitting in a car in your lot or working in the office next door, can reach it without walking through the front door. Your firewall can't help when the attacker connects from inside the building's signal, and a network pentest that starts from the internet never touches Wi-Fi at all.

Wireless also tends to drift. Someone sets it up once, it works, and nobody revisits it for years while passwords leak, staff turn over and old devices keep the weakest settings alive.

What do you test?

• Encryption and authentication. WPA2 and WPA3 settings, pre-shared keys weak enough to crack offline, and enterprise (802.1X) setups where devices hand over credentials to any network that asks.
• Guest network separation. Whether a device on guest Wi-Fi can reach internal systems, printers or management interfaces.
• Fake access points. Whether corporate laptops and phones will connect to an attacker's network that copies your network's name.
• Rogue access points. Unauthorized wireless devices plugged into your network that open a back door nobody approved.

Does a tester need to come on site?

No. We run wireless testing remotely. We ship a device to each location you want tested. If you have several locations, we'll help you pick which ones to test so you get a representative picture without paying to cover every building.

Will testing knock people off Wi-Fi?

Most wireless testing just listens. Some techniques briefly disconnect a single device so it reconnects and reveals what an attacker needs, which causes a short blip for that one device. We agree on which techniques are on the table before we start, and we can hold anything disruptive until after hours.

How long does it take, and what does it cost?

The number of sites and the number of wireless networks at each one drive the effort. Wireless testing often pairs well with an internal network penetration test, since a successful wireless attack leads straight into the internal network. Testing both together shows you the full path from the airwaves to your internal systems.

What do we get at the end?

You get a report that shows exactly what we reached and how, from cracked keys to the internal systems we could touch from the parking lot. Every finding comes with a specific fix, from changing a key to segmenting guest traffic or tightening certificate validation on your devices. We walk you through it, and you can ask the person who did the testing anything you want.
