Cybersecurity audit for SMBs and large companies

An undetected vulnerability, an overly permissive configuration, uncontrolled access, or an overlooked critical dependency can compromise your entire information system. The cybersecurity audit allows you to take a step back and assess your level of exposure, identify real risks, and prioritize the necessary actions.

We help small and medium-sized businesses, mid-market companies, and large enterprises assess their IT security: architecture, applications, infrastructure, cloud, workstations, access, governance, and internal practices. The goal: to transform a technical assessment into a clear, actionable, and prioritized action plan.

How do you conduct a cybersecurity audit?

A cybersecurity audit isn’t just about “finding vulnerabilities.” Above all, it helps identify where the most critical risks to the business lie: service interruptions, data theft, compromised accounts, ransomware, non-compliance, or poor access management.

Warning signs to watch for:

Rapid growth of the information system without a comprehensive security review
Cloud, SaaS, or line-of-business tools added gradually without a clear roadmap
Too many administrator accounts or accounts that are not adequately controlled
Recurring incidents: phishing, compromised accounts, antivirus alerts, network anomalies
An application overhaul, a cloud migration, or expanding to new partners
A customer, insurance, compliance, or executive requirement regarding the level of security

A corporate cybersecurity audit provides a concrete picture of the situation, moving beyond theoretical approaches. It helps distinguish critical issues from secondary optimizations.

How to choose the right cybersecurity audit?

A successful audit depends first and foremost on your specific context. An SME without a dedicated security team will not have the same needs as a multi-site company with several critical applications.

For an cybersecurity audit for an SME, it’s best to focus on a pragmatic assessment: internet exposure, backups, email, user workstations, administrator privileges, the cloud, antivirus/EDR, and basic procedures.

This approach quickly provides an overview of the most tangible risks. For a more structured organization, the audit can go further: network segmentation, IAM review, application security, penetration testing, cloud audit, compliance, monitoring, and incident response capabilities.

Identify Your Top Risks

Mistakes to avoid:

#01

Launching an audit without a clearly defined scope.
#02

Focusing solely on the technology and neglecting internal processes.
#03

Receiving a report that is too complex and difficult to translate into action.
#04

Treat all vulnerabilities with the same level of urgency.
#05

Do not plan for any follow-up after the handover.

A good audit should lead to a clear decision: what needs to be corrected, why, in what order, and with what level of effort.

What are the different types of cybersecurity audits?

Not all audits address the same need. The appropriate scope depends on your level of maturity, your business challenges, and your most critical assets.

This audit analyzes key components: network, servers, workstations, directory services, backups, configurations, user permissions, and external exposure. It highlights configuration vulnerabilities, sensitive access points, exposed services, and vulnerabilities that could facilitate an intrusion.

Our cybersecurity audit services

Our cybersecurity audit services cover technical, organizational, and operational aspects. Each engagement results in prioritized findings, along with recommendations that are easy for IT, business, and executive teams to understand.

Request your audit

We begin by identifying critical assets: applications, sensitive data, infrastructure, business tools, privileged accounts, cloud environments, and exposed services. This step helps avoid overly broad audits that yield little actionable insight.

Our Cybersecurity Audit Methodology

#01

Identifying Key Issues and Sensitive Assets

We coordinate the scope with your IT, business, and executive teams. Critical data, strategic applications, external access, and dependencies on service providers: every sensitive element is identified prior to the analysis.

#02

Auditing with a Business Perspective

Technical audits are interpreted based on your actual usage. A vulnerability does not have the same impact depending on whether it affects a showcase website, a customer portal, an ERP system, or a sales database.

#03

Present a clear, prioritized plan

The report distinguishes between critical risks, immediate actions, and long-term initiatives. It provides you with a clear overview to help you make decisions, allocate budgets, and organize corrective measures.
