Comprehensive IT security audit covering infrastructure, Microsoft 365, identity management, processes and policies. Report with 50–100 concrete recommendations prioritized by risk. Foundation for NIS2, ISO 27001 or gap remediation. Audit in 3–6 weeks.

01

No knowledge of company cybersecurity state

02

Incident impact dwarfs the cost of prevention

03

External auditors (ISO, NIS2) require internal audit

Customer problem

You don't know how you stand in cybersecurity — and incidents are far more expensive than prevention

Leadership asks: how do we stand in cybersecurity? Most companies can't answer. No audit = no knowledge = no plan. Meanwhile the operational, regulatory and reputational consequences of an incident dwarf the cost of preventing it.

An IT security audit gives you the full picture. What works well, where the gaps are, what's priority, how heavy the remediation will be. Report with 50–100 recommendations prioritized by risk. Foundation for any cybersecurity project: NIS2, ISO 27001, vCISO, specific area remediation.

Business benefits of audit

Full cybersecurity state knowledge

Leadership knows how company stands. Concrete facts, not opinions. Foundation for every cybersecurity decision.

Priorities and budget

50–100 prioritized recommendations. You know what to do first, what it costs. 12–24 month plan.

Foundation for compliance

Audit is foundation for NIS2, ISO 27001, ISO 27017. Without audit compliance rollout is impossible.

Who this is for

Who this is for

Companies before NIS2 / ISO 27001 rollout

Organizations for whom audit is first step before compliance rollout.

Companies with B2B customer requirements

Organizations for whom B2B customers (especially large) require audit as contract condition.

Companies after cybersecurity incident

Organizations wanting to understand what happened and prevent in future.

Companies before M&A transaction

Investors and buyers require cybersecurity audit as due diligence part.

FAQ

FAQ about IT security audit

How long does IT security audit take?

Typically 3–6 weeks. Small company (up to 50 people) — 3 weeks. Medium (100–300 people) — 4–5 weeks. With penetration tests — additional 1–2 weeks.

What does the audit cover?

Technical audit (infrastructure, M365, IAM, network, backup, monitoring), process audit (policies, procedures), compliance audit (GDPR, NIS2, ISO), team interviews. Optionally penetration tests.

Will audit reveal compliance problems?

Yes. That's the audit's goal — finding gaps. Important: report is confidential, for your company. Gives you chance to fix before external audit (NIS2, ISO).

What scope do you offer for an audit?

We work in three variants — a small audit (up to 50 people), a medium audit (100–300 people) and an enterprise audit with penetration tests. We pick the scope after a brief call about company size, environment maturity and the goal of the audit (NIS2, ISO, post-incident, due diligence). The investment typically pays back in the first compliance rollout.

Do you do penetration tests?

Yes, optionally. We have partners doing penetration tests (white box, black box, hybrid). MITRE ATT&CK-based report. CVE vulnerability identification.

Is audit discrete?

Yes. Standardly audit is invisible to most employees (except IT and selected key roles). NDA on full scope. Report only for leadership.

What after audit report?

We can offer recommendation implementation plan (as project) or vCISO subscription. Or leave you with report and you decide on next steps with own team.

In-depth analysis

IT security audit — what to know

IT security audit is comprehensive cybersecurity review of company: infrastructure, Microsoft 365, identity and access management, processes, policies, regulatory compliance (GDPR, NIS2, ISO 27001). It's the foundation for every cybersecurity project — you can't effectively rollout NIS2, ISO 27001 or hire vCISO without prior audit.

Good audit isn't just technical scan. It's a project covering technical audit, process and policy audit, IT team and key role interviews, regulatory compliance assessment, optionally penetration tests. Result: 50–100 page report with concrete recommendations prioritized by risk.

Audit delivers biggest impact for companies before NIS2/ISO 27001 rollout (as gap analysis), companies with B2B customer requirements (as cybersecurity proof), companies after incident (as root cause analysis), and companies before M&A transaction (as due diligence element). Typically audit returns in first compliance rollout through avoiding mistakes and inefficient projects.
