Security audit
Independent assessment of your processes, configurations, and compliance with NIS2, the Cybersecurity Act, and ISO 27001. Identify your weak points and determine what needs to be addressed as a priority.
Request a security auditWhat is a security audit?
A security audit is an independent, structured assessment of your organization’s overall level of cybersecurity. Unlike penetration testing, which actively attacks systems to find exploitable vulnerabilities in practice, an audit focuses on processes, policies, configurations, and compliance with standards and legislative requirements.
It answers the question “Are we doing the right things correctly?” – rather than “Can an attacker penetrate our firewall?” Both approaches complement each other: an audit reveals gaps in management and processes, while a penetration test verifies whether these gaps are actually exploitable.
When is an audit necessary?
You are preparing for ISO 27001 certification or compliance with NIS2 / the Cybersecurity Act
You want to know your status before a NÚKIB regulatory inspection
A security incident has occurred and you are looking for systemic causes
The organization is growing and security processes cannot keep up with the pace of change
Suppliers or partners require proof of security maturity
What does a security audit include?
A comprehensive cyber audit covers five key areas that together form the organization’s overall security profile.
Security policies and processes – whether they exist, are up to date, and are followed by personnel
Technical security and configuration – servers, networks, firewalls, VPNs, encryption, patching
Access and permissions – IAM, principle of least privilege, protection of privileged accounts
Backup, recovery, and continuity – backup functionality, recovery testing, BCP and DRP plans
Cloud and hybrid environments – Microsoft 365, Azure, AWS, Google Cloud
How does the audit work?
Our audit process is structured into five phases, ensuring systematic coverage and clear outputs.
Kick-off and scope definition
Together, we define the scope of the audit, key systems and areas, the schedule, and contact persons on your side. We agree on the methodology and sign a Non-Disclosure Agreement (NDA). The goal is for both parties to know exactly what the audit will and will not cover.
Data collection and documentation
We collect supporting materials: security policies, network diagrams, asset inventory, records of previous audits and incidents. We conduct structured interviews with IT administrators, managers, and the security team, supplemented by technical configuration checks.
Assessment and analysis
We evaluate the collected data against reference frameworks (ISO 27001, NIS2, NIST CSF, CIS Controls). We identify gaps and assess their severity. The result is a clear risk map prioritized by impact and probability.
Preparation of the audit report
We prepare a detailed written report with findings, severity ratings, context, and specific recommendations. Each finding includes a description, evidence, risk, and recommended remediation steps – not generic advice, but solutions tailored to your environment.
Presentation and roadmap
We present the results to your management and IT team. We explain priorities and help create a realistic roadmap for corrective measures. Upon request, we also provide follow-up verification (re-audit) of the implementation of recommendations.
Audit output
Upon completion of the audit, you will receive a comprehensive set of documents and materials for strategic decision-making.
Audit report – findings sorted by severity, with evidence and recommendations
Gap analysis – where you stand compared to ISO 27001, NIS2, or the Cybersecurity Act
Prioritized roadmap – quick wins, medium-term, and long-term measures
ISMS documentation – direct input for ISO 27001 certification
Regulatory compliance: NIS2, Cybersecurity Act, GDPR, and ISO 27001
Regulatory pressure on cybersecurity in the Czech Republic is growing significantly. Key frameworks include:
NIS2 and the Cybersecurity Act
The Czech Republic has transposed the NIS2 directive through a completely new Cybersecurity Act (No. 264/2025 Coll., effective from November 1, 2025), which replaced the previous Act No. 181/2014 Coll. Regulated service providers – in both higher and lower obligation regimes – must implement appropriate security measures according to Decrees No. 409/2025 Coll. and No. 410/2025 Coll. and report incidents to NÚKIB. A security audit is a fundamental tool for verifying compliance and preparing for inspection.
GDPR
GDPR requires appropriate technical and organizational measures to protect personal data. A security audit identifies whether your measures truly correspond to the processed data and risks.
ISO/IEC 27001:2022
The international standard for Information Security Management Systems. An audit according to Annex A of the 2022 revision covers 93 security controls and forms the basis for a certification audit. SysnetShield will help you navigate the requirements and set a realistic path to certification.
Non-compliance with the Cybersecurity Act can lead to a fine of up to CZK 250 million or 2% of total global annual turnover (higher obligation regime), and up to 4% of turnover for GDPR. A security audit is an investment, not a cost.

What sets us apart
Specialized team, not subcontractors
We are not a consultancy firm that resells work. Every project is led directly by members of our team with full responsibility for the result.
Manual work, not just automated tools
Automated scanners detect known vulnerabilities. Logic errors, business-logic flaws, and exploit chains can only be uncovered by an experienced tester who thinks like an attacker.
Actionable outputs
The report is not an academic exercise. It is written so that your dev or ops team can start remediation immediately–with specific steps and links to resources.
Tailored scenarios, not templates
We build every project according to your environment, your risks, and your goals. We do not use off-the-shelf methodologies or generic templates.
Discretion and confidentiality
We sign an NDA before every project. All information and results remain exclusively between us and you.
Compliance with international standards
The methodology is based on OWASP, PTES, and NIST and is in compliance with NIS2 and the Cybersecurity Act–meaning it is recognized by regulators and auditors.
Frequently Asked Questions
A security audit evaluates processes, policies, and configurations – answering whether you are doing the right things correctly. A penetration test actively attacks your systems to verify if a vulnerability is realistically exploitable. Both approaches complement each other; many clients start with an audit and follow up with a pentest on critical areas.
The duration depends on the scope and size of the organization. For small and medium-sized companies, an audit usually takes 1 to 3 weeks, including report preparation. For large organizations with complex infrastructure, the scope may be larger. We will agree on the exact schedule at the kick-off meeting.
It is not a requirement – the absence of documentation is a finding in itself. It helps if you have access to network diagrams, asset inventories, and existing security policies. If you don’t have them, the audit will help you identify what needs to be created.
Audit outputs are highly sensitive documents. We work exclusively under a Non-Disclosure Agreement (NDA). You will receive the report, and no third party will. We also recommend limiting the distribution of the report within the organization to the necessary minimum.
No. We maintain strict confidentiality. All findings are communicated exclusively to you. We are not a regulator or a supervisory body – our goal is to help you rectify the situation, not to punish you.
NÚKIB, as the national supervisory authority for cybersecurity, may require regulated service providers to document the security measures they have adopted. Our audit outputs are structured to serve directly as a basis for communication with NÚKIB and potential inspections.
Yes. Beyond the audit itself, we offer consulting support for the implementation of corrective measures, assistance with ISO 27001 certification preparation, and follow-up penetration testing to verify the effectiveness of the changes.
