Professional WiFi Penetration Testing
47% of companies have WiFi vulnerabilities allowing full access to corporate network. We test WPA2/WPA3, guest isolation, rogue AP, evil twin. Find vulnerabilities before an attacker in the parking lot exploits them.
What is Professional WiFi Penetration Testing?
Professional WiFi Penetration Testing simulates real-world wireless attacks — WPA2/WPA3 cracking, evil twin access points, rogue AP detection, and guest-to-corporate network isolation testing — performed from outside the building, exactly as an attacker in a parking lot would operate. nFlo's OSWP-certified testers deliver a full site survey, signal coverage heatmap, and prioritized remediation recommendations; 47% of companies have critical WiFi vulnerabilities that can give an external attacker direct access to the corporate network.

Data Theft Through Guest WiFi - Case Study
A consulting firm provided guest WiFi without proper segmentation. An attacker connected as “guest”, but thanks to VLAN misconfiguration had full access to corporate network. Within 2 hours:
- Scanned internal network
- Found unsecured SMB share
- Exfiltrated 50 GB of sensitive client documents
Cost: €800K (GDPR fines, reputation damage, client lawsuits). The attacker was sitting in a cafe next to the office.
Without WiFi security testing:
- No isolation between guest and corporate network
- Weak WPA2 passwords vulnerable to offline cracking
- Unauthorized access points (rogue AP) connected by employees
- Vulnerability to evil twin and credential harvesting attacks
We Test Like an Attacker From the Parking Lot - No Physical Access Needed
We don’t need to enter the building. We test everything that can be done from outside - just like a real attacker sitting in a car in front of the building.
What you get:
- Map of all WiFi networks in range (SSID, channels, signal strength)
- Rogue access point identification (unauthorized APs)
- WPA2/WPA3 password strength tests (offline cracking)
- Evil twin attack simulation (fake WiFi with same SSID)
- Guest/corporate network isolation verification
- Client isolation tests (can guests see each other)
- Captive portal bypass testing
- WPS vulnerability analysis (if enabled)
- Signal coverage heatmap (where WiFi extends beyond building)
- Report with prioritized recommendations
Who Is It For?
This service is for you if:
- You provide WiFi to guests and want to ensure they’re isolated
- You’re concerned about attacks from parking lot or neighboring offices
- You want to detect rogue access points connected by employees
- You need to verify WiFi security policy implementation
Test Scope
What We Test
1. Wireless Site Survey
- Mapping all SSIDs in range
- Channel and signal strength identification
- Detecting overlapping networks
- Coverage analysis (where signal extends beyond building)
2. Rogue Access Point Detection
- Unauthorized AP identification
- Detecting APs connected to corporate network
- Physical location of rogue AP (triangulation)
3. WPA/WPA2/WPA3 Security Testing
- Password strength analysis (dictionary, brute-force offline)
- WPS tests (Pixie Dust, PIN brute-force)
- Downgrade attacks (WPA3 → WPA2)
- Dragonblood vulnerabilities (WPA3)
4. Evil Twin Attacks
- Fake WiFi simulation with identical SSID
- Credential harvesting through captive portal
- Man-in-the-middle attack simulation
- SSL strip testing
5. Client Attacks
- Deauthentication attacks
- KARMA attacks (auto-connect exploitation)
- Client isolation testing
- Packet injection
6. Network Segmentation
- VLAN isolation verification (guest vs corporate)
- Access tests to corporate resources from guest WiFi
- Firewall rules verification
- Access control testing
7. Captive Portal
- Bypass techniques
- Session hijacking
- DNS tunneling
- MAC spoofing
Methodology and Tools
We use professional tools and methodology:
- Aircrack-ng suite - WPA cracking, packet injection
- Wifite2 - automated wireless attacks
- Reaver/Bully - WPS attacks
- Hostapd-wpe - evil twin setup
- Ekahau - professional site survey

Common questions about Professional WiFi Penetration Testing.
Do WiFi tests require access to our office?
We test like a real attacker - from outside the building, without physical access. We check what can be done from the parking lot or neighboring premises. On request, we also conduct internal tests (post-authentication).
How long do WiFi penetration tests take and what do I receive in the report?
Tests take 3-5 business days. The report includes a map of all WiFi networks in range, a list of rogue APs, WPA2/WPA3 test results, guest/corporate isolation assessment, a signal coverage heatmap and prioritized remediation recommendations.
Won't the tests disrupt our WiFi network?
We agree on the scope with you before testing. Deauthentication and evil twin attacks may briefly affect connections - we conduct them in an agreed time window or outside peak hours.
We have WPA3 - is our WiFi secure?
WPA3 is significantly more secure than WPA2, but attack vectors still exist: Dragonblood vulnerabilities, downgrade attacks to WPA2, rogue APs, guest network segmentation issues. We test all these scenarios.
