An internal penetration tester is on site assessing network access for company-owned mobile devices.

WiGLE.net is the best choice because it is purpose-built for identifying and mapping wireless networks (SSIDs/BSSIDs) using aggregated wardriving-style data and location-based search. In PenTest+ reconnaissance, testers often need to quickly determine what wireless networks are present in or around a physical location—especially when assessing how corporate mobile devices might encounter nearby SSIDs that could be abused for evil-twin or misassociation scenarios. WiGLE helps identify networks by area and provides details that support follow-on testing decisions, such as which SSIDs are common, whether naming patterns suggest corporate ownership, and whether nearby networks could confuse users or devices.

Wireshark is a packet analyzer and requires traffic capture; it is not a discovery database for “what networks exist” in a geographic area. theHarvester and Recon-ng are OSINT tools oriented toward emails, domains, hosts, and identity data—not local wireless network identification. For the stated goal of identifying available Wi-Fi networks for mobile-device exposure assessment, WiGLE.net most directly fits the objective.
