System Audit
-
Are your systems truly protected against external threats?
As cyberattacks grow in complexity and frequency, the key question is whether your systems are adequately secured. While vulnerability scans can detect known weaknesses, comprehensive protection demands more. Only a robust, well-designed security architecture, coupled with strong security awareness across your organization, can provide the necessary defense.
-
Is your security architecture built for the future?
In a system audit, we evaluate the architecture of your IT systems and networks to ensure long-term resilience. From network and collaboration security to hybrid and cloud environments and endpoint protection, we thoroughly analyze all critical areas. We also provide guidance on how to integrate these systems effectively for maximum protection and early detection of security incidents.
-
Are your systems fully aligned with current best practices?
Our experts assess your security system configurations, comparing them against manufacturer guidelines and industry best practices. Any deviations are identified, and we provide clear, actionable recommendations for improvement.
-
Are there vulnerabilities in your data systems and software components?
A vulnerability assessment helps uncover weaknesses in both your internal and external systems. Whether through a one-time evaluation or ongoing monitoring, we enable you to regularly assess the security of your systems and promptly address any identified vulnerabilities.
-
How can you effectively implement security policies from the Security Office?
Ensuring compliance with security policies can be challenging, as engineers often find it difficult to accurately interpret and apply guidelines from the Security Office. We help you understand your security standards, implement suitable solutions, and demonstrate compliance through thorough audits.
Internal Audit
-
Are you compliant with relevant regulations and standards?
Our security audit ensures that your Information Security Management System (ISMS) adheres to current legal regulations, including the new Data Protection Act (nDSG) and the Information Security Act (ISG). We also evaluate compliance with recognized standards such as ISO 27001, TISAX, and IT Baseline Protection.
Beyond compliance assessment, we foster understanding among key stakeholders regarding any deviations and provide guidance on closing security gaps. Our objective is to thoroughly prepare you for external audits, complete with all necessary documentation.
-
Are your security policies clearly understood and effectively implemented?
A lack of understanding of security policies can result in incorrect implementation. In our internal audit program, we prioritize clearly communicating the requirements and their protective benefits to ensure that all guidelines are applied correctly and consistently.
-
Is your data storage compliant with the nDSG?
The new Data Protection Act (nDSG) presents many organizations with new challenges. Our audit program assesses the current state of your data processing practices and helps prioritize the necessary measures for compliance, minimizing the risk of fines and security vulnerabilities.
-
Are your IT processes adequately documented and easily accessible?Comprehensive and clear documentation of IT processes is essential for your organization’s security. We assess whether your processes meet established requirements and if they are understandable and applicable for employees. This evaluation helps minimize security risks and improve operational efficiency.
-
Are you prepared for the certification audit?
Our internal audit program specifically prepares you for the certification audit. In addition to ensuring your Information Security Management System (ISMS) is well-documented, we provide valuable insights into what external auditors examine, the required evidence, and how to present your organization effectively. This preparation enables you to approach the certification audit with confidence.
Effective Learning: Integrating audits with security awareness allows you to identify vulnerabilities and leverage those insights to drive sustainable improvements.

Practical Relevance, Experience, and Technical Expertise: Leverage our industry experience and practical solutions drawn from numerous implementation projects. Our extensive technical knowledge guarantees thorough and accurate system audits.
FAQ Security Audit
-
What is the difference between an Internal Audit and a System Audit?
-
An internal audit checks compliance with a standard or regulation. In the context of ISO 27001, this is an ongoing process that validates the entire ISMS, including policies, processes, and systems, over a three-year period and supports the continuous improvement process. System audits are also conducted to verify compliance with the requirements on a sample basis. Another example would be a targeted review according to the requirements of the new Data Protection Act.
-
A system audit focuses on a specific system or system landscape and examines its security against your requirements. This can include internal directives, recognized standards or regulations, manufacturer best practices, or the general state of the art.
For example, a task might involve investigating compliance with the encryption policy in the WAN and remote access environment. Alternatively, we could review the configuration of email communication according to the current state of the art.

-
How is the audit team assembled?
Depending on the assignment and requirements, we provide the appropriate consultants. In a system audit, these are technically trained professionals with extensive experience. For an internal audit, we send a team consisting of GRC-certified consultants, along with technical consultants.
-
Why should you outsource an internal audit?
An internal audit also demands independence and skills from the auditors. By engaging an externally appointed team, you can more easily demonstrate this independence. Our consultants bring not only certification but also relevant experience from numerous other projects.
In the context of ISO 27001, external auditors refer to those who conduct the certification audit. BNC intentionally does not offer this service because we want to actively advise and support you, which external auditors cannot do to maintain an impartial assessment.
-
What is the purpose of the results report?
Our goal is to provide you with not only a list of audit results but also feedback on what is working well and how you can improve concretely. The results report primarily serves as proof that you have implemented a proper internal audit program.
-
What standards are supported by BNC?
BNC currently supports you in achieving compliance with the following standards and regulations as part of internal audit measures:
- ISO/IEC 27001
- ISO/IEC 27005
- TISAX
- Swiss Data Protection Act (nDSG) and European GDPR / DSGVO
- Swiss Information Security Act and European NIS-2
- ICT Basic Protection for the Federal Administration
