Network Security Audit for Swiss SMEs

60% of SMEs hit by a cyberattack cease operations within 6 months. Our network audits based on ISO 27001 and NIST CSF identify vulnerabilities before they are exploited — penetration tests, nFADP compliance, prioritised report.

Is your network truly secure?

60% of SMEs hit by a cyberattack cease operations within 6 months (National Cyber Security Alliance). Your network is the backbone of your information system — but also its primary attack surface. Misconfigured routers, VPN without MFA, absent segmentation: these vulnerabilities are exploited daily by automated attackers.

The average detection time for a network intrusion is 204 days (IBM Cost of a Data Breach 2023). In 204 days, an attacker can exfiltrate all your customer data, encrypt your servers and paralyse your operations. A network security audit identifies these attack vectors before they are exploited.

Security Inspection

Audit: Complete Analysis of Your Security Systems

A network security audit is a systematic assessment of your IT infrastructure designed to identify vulnerabilities, test resilience against intrusions and verify compliance with ISO 27001/27002 and NIST CSF standards. At Bexxo, our audits cover your entire architecture: active equipment, segmentation, protocols, remote access and encryption.

What does a network security audit check?

Comprehensive assessment based on ISO 27001/27002 and NIST CSF standards: IT infrastructure, security policies, critical assets. 60% of SMEs hit by a cyberattack cease operations within 6 months (National Cyber Security Alliance).

icon

Can my network withstand a real attack?

Attack simulation in White Box, Grey Box or Black Box mode to discover exploitable vulnerabilities and assess your defences' resilience. Penetration tests reveal on average 3 to 5 critical vulnerabilities per SME infrastructure.

icon

Is my infrastructure compliant with the nFADP?

Verification of compliance with standards and regulations (nFADP, ISO 27001). Identification of compliance gaps and recommendations for remediation. nFADP fines: up to CHF 250,000 for violations.

icon

What are the real risks for my business?

Assessment of potential threats, measurement of the impact on your operations and prioritisation of actions to take. The average cost of a data breach reaches USD 4.45M (IBM Cost of a Data Breach 2023).

icon

What does the audit report contain?

Clear summary of findings, detailed action plan prioritised by criticality and presentation to your team. The report serves as proof of due diligence in the event of a FDPIC inspection or incident.

Test Types

Types of Security Tests

icon

White Box

White box tests involve a thorough assessment of the internal architecture and source codes. These tests allow us to understand the internal workings of the system and identify potential vulnerabilities.

  • Le plus complet
  • Le plus cher
icon

Grey Box

Grey box tests combine elements of white box and black box tests. In this approach, we have partial knowledge of the system's internal architecture, or even the source codes. These tests are effective for identifying vulnerabilities related to design flaws.

  • Le standard
  • Complet et réaliste
icon

Black Box

Black box tests, or external security tests, evaluate the system without any prior knowledge. We therefore produce external attacks to identify vulnerabilities exploitable from the outside. This method is particularly useful for assessing the application's security from the perspective of a potential attacker.

Infrastructure Assessment and Strengthening

Audit of your current network, identification of weak points and recommendations for a secure architecture. 85% of security breaches exploit network configuration errors (Gartner).

icon

Perimeter Protection

Configuration of next-generation firewalls (NGFW), deployment of intrusion detection systems (IDS/IPS) and network segmentation. Segmentation reduces the impact of a breach by 67% on average (Cisco).

icon

Access Security

Implementation of VPN, identity and access management (IAM), multi-factor authentication (MFA). 99.9% of account attacks are blocked by MFA (Microsoft).

icon

Protection against Advanced Threats

Deployment of anti-malware solutions, web and email traffic filtering, data loss prevention (DLP). Ransomware costs an average of USD 1.85M per incident (Sophos State of Ransomware 2023).

icon

Monitoring and Response

24/7 monitoring of your network, rapid detection of anomalies and incident response plan. The average time to detect a breach is 204 days (IBM) — active monitoring reduces this delay drastically.

Frequently asked questions about network security audits

What is a network security audit?

A network security audit is a systematic assessment of a company's IT infrastructure: active equipment (routers, switches, firewalls), segmentation, communication protocols, access management and encryption levels. At Bexxo, our audits reveal on average 3 to 5 critical vulnerabilities per SME infrastructure.

How much does a network security audit cost?

Our network packages range from CHF 2,000 (Essential — vulnerability scan, simplified report) to CHF 18,000 (Premium — in-depth penetration tests, full assessment, management presentation). The Standard package (CHF 4,500) is the most requested by Swiss SMEs.

How long does a network audit take?

From 2 to 10 business days depending on the package and the size of the infrastructure. The Essential package takes 2 to 3 days, the Standard 3 to 7 days, the Premium 5 to 10 days. You receive a detailed report with a criticality-prioritised action plan at the end of the audit.

What is the difference between White Box, Grey Box and Black Box for a network?

White Box provides access to network diagrams and configurations (most comprehensive, ideal before ISO certification). Grey Box simulates an employee or contractor with partial VPN access (most balanced for SMEs). Black Box tests from the outside with no prior knowledge, like a real attacker. Bexxo recommends Grey Box as the standard for SMEs.

Is my network subject to the nFADP?

Yes. The nFADP (new Federal Act on Data Protection, in force since September 2023) requires appropriate technical security measures for all personal data processed. A network intrusion causing a data leak can result in fines of up to CHF 250,000 and an obligation to notify the FDPIC.

Can the network audit report be used for ISO 27001 certification?

Yes. Our audits follow the controls of ISO 27001:2022 (Annex A — technological and physical controls) and the NIST CSF as reference frameworks. The audit report constitutes documentary evidence of due diligence for ISO auditors, the FDPIC and your business partners.
