Assessment

Wi-Fi penetration testing

Keep your wireless networks secure and protect your sensitive communications.

§ 01 · Overview

What is a Wi-Fi pentest?

Wi-Fi networks, whether used internally, for visitors or for sensitive services, are a prime target for attackers.

A Wi-Fi penetration test detects the security weaknesses that could compromise your data and allow unauthorized access to your systems.

Objectives

Our audits highlight realistic risk scenarios, including:

  • Interception of sensitive data

  • Denial of service

  • Rogue hotspot setup

  • Pivoting from Wi-Fi to the internal network

§ 02 · Approach

The HELX approach

Our Wi-Fi penetration tests simulate real-world attacks to detect the vulnerabilities present on your access points. We use advanced tools and techniques to assess how well your wireless network holds up. After the audit, you receive a detailed report with practical recommendations to fix the weaknesses and harden your Wi-Fi access.

§ 03 · Formats

Audit types

During our Wi-Fi audit, we pick with you the approach best suited to your network. Each scenario tests a different aspect of your wireless infrastructure security.

Black box

Simulates an external attacker with no prior access to the network. We test the security of your access points from the outside.

Gray box

Starting from access to your Wi-Fi network, we test internal weaknesses, access points and reachability of neighboring networks.

White box

We review the configuration of access points, passwords and security filters to assess the security of your network.

§ 04 · Methodology

Methodology

Our Wi-Fi penetration tests follow a rigorous methodology covering the full range of potential vulnerabilities in your wireless network, from access point configuration flaws to authentication mechanisms.

  1. 01

    Scope discovery

    Identification of active Wi-Fi networks (visible and hidden SSIDs). Collection of access point information: BSSID, channels, security protocols, signal strength, and detection of devices connected to the network.

  2. 02

    Protocol analysis

    Review of the security protocols in use (WEP, WPA, WPA2, WPA3). Analysis of authentication mechanisms and security configurations, including WPS settings.

  3. 03

    Vulnerability research

    Identification of protocol-specific vulnerabilities such as KRACK or Evil Twin attacks. Testing of client de-authentication mechanisms. Search for misconfigured or vulnerable access points.

  4. 04

    Exploitation

    Capture and cracking of Wi-Fi keys (brute force or dictionary attacks). Deployment of rogue access points to intercept network traffic. Exploitation of connected devices to infiltrate the target network.

  5. 05

    Network access and segmentation

    Verification of internal subnet isolation and separation of secured zones after initial access. Verification of guest network segmentation.

  6. 06

    Analysis and report

    Analysis of the results, presentation of the vulnerabilities found, and recommendations to harden your wireless network.

§ 05 · Vulnerabilities we look for

A bit of technical detail

Wi-Fi attack techniques and vulnerabilities are well known and widely documented; they let us hunt for the critical weaknesses in your wireless networks:

  • Unauthorized access: brute-force attacks, WPA2 cracking
  • Interception of sensitive data: sniffing, man-in-the-middle
  • Weak security protocols: WEP, WPA, WPA2
  • Denial-of-service attacks: DoS, jamming
  • Insecure access points and phishing: rogue AP
  • Exploitation of router configuration flaws

FAQ

Frequently asked questions

How much does a Wi-Fi penetration test cost?

Between €1,700 and €5,950 excl. VAT depending on the networks in scope (corporate, personal, guest) and the approach, debrief included. It is one of the most cost-effective tests relative to the risk it covers, and small businesses, SMBs and non-profits get a 15% discount.

What exactly do you test?

Depending on your networks: strength of RADIUS authentication (WPA-Enterprise), pre-shared key attacks (WPA-Personal), captive portal and guest network segmentation, rogue APs and evil twin attacks against your staff.

Do you need to come on site?

Yes: Wi-Fi cannot be audited remotely, so a consultant travels with their equipment. The visit is short, one to three days, and discreet.

Our guest Wi-Fi is isolated, is that enough?

That is exactly what we verify: the actual isolation between the guest network and the internal IT environment is one of the most common flaws we find, and one of the most exploited.
