NexusSec.Wireless penetration testing assesses whether your Wi-Fi can be used as an entry point into your network. We test authentication strength, whether guest networks are genuinely isolated, whether staff devices can be lured onto rogue access points, and — most importantly — what an attacker actually reaches once connected. Wi-Fi is the one network boundary an attacker can probe from the car park.
Why wireless deserves separate attention
Every other network entry point requires either physical access or an internet-facing service. Wi-Fi radiates beyond your walls, so an attacker can attempt entry from the car park, the neighbouring office or the street — with no physical access and no exposure on your perimeter firewall.
What we test
| Area | What we assess |
|---|---|
| Authentication | WPA2/WPA3 configuration, pre-shared key strength, enterprise (802.1X) implementation and certificate validation |
| Guest isolation | Whether guest Wi-Fi genuinely reaches only the internet, and whether client isolation is enforced |
| Segregation | What corporate wireless clients can reach — servers, management interfaces, backups |
| Rogue AP resistance | Whether devices can be tricked into associating with an impersonated network (evil twin) |
| Client behaviour | Whether laptops and phones leak credentials or auto-connect to spoofed SSIDs |
| Management plane | Controller and access-point administration exposure and default credentials |
| Coverage leakage | How far usable signal extends beyond your premises |
What we commonly find
- Guest networks that are not actually isolated — reaching printers, internal ranges or management interfaces.
- A single shared pre-shared key known to former staff, contractors and visitors, never rotated.
- Corporate Wi-Fi landing on the same flat network as servers, so any wireless compromise is immediately serious.
- 802.1X without proper certificate validation, allowing credential relay through an impersonated network.
- Forgotten SSIDs — an old network still broadcasting with legacy security.
- IoT devices sharing corporate Wi-Fi, providing a soft entry point.
The finding that matters most is rarely "the Wi-Fi password is weak". It is what the wireless network connects to. Wireless should terminate in its own segment with firewall policy to internal resources — see network segmentation.
Our approach
- Scoping — sites, SSIDs, permitted techniques and timing agreed in writing, with client authorisation confirmed for each location.
- Survey — identifying all broadcasting networks, including ones you may not know about, and mapping signal reach.
- Authentication testing — assessing the strength and implementation of your wireless security.
- Segregation testing — connecting as guest and as corporate client, then establishing exactly what each can reach.
- Rogue AP testing — where authorised, assessing whether devices can be induced to associate with an impersonated network.
- Reporting — findings prioritised by real business risk with specific remediation.
Wireless testing requires an on-site visit, which we schedule around your operations across Navi Mumbai and Mumbai.
Practical recommendations
- Put corporate, guest and IoT wireless on separate segments with firewall policy between them.
- Use 802.1X with proper certificate validation for corporate access rather than a shared key.
- Enforce client isolation on guest networks.
- Rotate pre-shared keys when staff leave, if you must use them.
- Decommission old SSIDs — they are frequently the weakest path in.
