IT Infrastructure Audit: What Is Checked and How to Prepare

An IT infrastructure audit is a systematic review of a company’s IT estate — infrastructure, information systems, security, licences, processes and documentation — designed to establish objectively what state your IT is really in, where the risks sit and what needs fixing first. The outcome is not an opinion but a documented report with findings, a risk assessment and a prioritised action plan you can use to make decisions about next steps, budget, security and suppliers.

Most executives know only as much about their IT estate as the person or vendor managing it chooses to tell them. An audit removes that information asymmetry: it shows whether backups are actually being made and restored, how reality compares with the expectation — how long a restore genuinely takes and how recent the recovered data really is — who actually owns the accounts and licences, which equipment is ageing, which processes exist only by word of mouth, and a good deal more. That is what makes planning possible instead of firefighting.

This page explains when an IT infrastructure audit is worth commissioning, what exactly is examined, how the process runs step by step and what your company should prepare so the audit goes smoothly.

When a company needs an IT infrastructure audit

An audit is not a compulsory ritual — it is done when you need reliable information about the real situation, so that decisions rest on facts. The most common situations:

• Before taking over an IT estate. When the responsible employee, IT manager or support partner changes, an audit records what is being handed over and what state is being taken on: equipment, access credentials, documentation, commitments.
• Preparing for NIS2 requirements. Before implementing security controls you need to know your starting point — the audit becomes the baseline. Whether the directive applies to your organisation is covered on our NIS2 requirements page.
• After a security incident. Following a breach, data loss or extended outage, an audit answers why it happened and which gaps remain open.
• When changing your IT support provider. Your existing vendor will not assess its own work objectively, so the real state is recorded either by an independent auditor engaged by the company or by the incoming provider, for whom documenting the current situation is an essential part of the takeover. The transition as a whole is described on the page Changing your IT support provider.
• When planning the IT budget. An audit shows where money is being spent inefficiently — unused licences, duplicated systems, ageing hardware — and which investments are genuinely necessary, in what order of priority.

Who can carry out an audit objectively

In practice there are two sources of an objective IT infrastructure audit, and your current support provider is neither of them. A vendor whose work the company is unhappy with will not audit itself — nobody hands a client a report on what they themselves did badly. Even a well-intentioned self-assessment remains a view from the inside.

• An independent auditor engaged by the company. A neutral third party with no interest on either side. This is a separate paid service with its own budget and timeline, and the auditor’s responsibility ends with the report — whatever is found still has to be fixed by somebody else.
• The incoming support provider. For them, recording the current state is an essential part of the takeover: without documenting what they are taking on, they cannot accept responsibility for it. The audit therefore forms part of the takeover work rather than a service the company pays for separately.

In most cases the incoming provider’s audit is the more useful of the two — and not only because it is not billed separately. The new provider has every reason to record the true, unvarnished state, because from the moment of takeover it answers for that state itself: every gap concealed or overlooked soon becomes its own problem. The recorded starting point also becomes the baseline against which it will later demonstrate progress. Speed helps too — the audit runs alongside the takeover rather than as a separate project ahead of it, so findings turn into work straight away.

Either way, the findings are discussed with the company: together you agree which items are critical, which can wait for a planned upgrade and in what order they will be addressed. That turns the report into an agreed, prioritised action plan rather than another document in a drawer.

What an IT infrastructure audit examines

The scope is tailored to the size and goals of the company, but the core is almost always the same: infrastructure, licences, security, backups, documentation, processes and access management. The table below lists each area together with the findings auditors encounter most often.

How the audit runs: step by step

1. Agreeing goals and scope. We discuss why the audit is being done — handover, security, budget — and which areas matter most; this determines the depth and duration, the auditor competencies required and the audit tools used.
2. Information gathering. Auditors review existing documentation, contracts and licence lists, interview the responsible staff and, where agreed, deploy automated inventory, monitoring or other tools.
3. Technical inspection. The state of the infrastructure, security configurations, backup operation and restore capability, and access lists are verified.
4. Process assessment. How incidents are logged and resolved and how changes and access are managed is evaluated against ITIL and COBIT good practice.
5. Analysis and risk assessment. Each finding is rated by its impact on the business and the likelihood of the problem materialising.
6. Report and discussion. Results are documented and presented to management in plain language — with concrete priorities, not technical jargon. The findings and the order in which they will be addressed are agreed with the company, so the audit ends not with a list of recommendations but with an agreed action plan.

What your company should prepare

The audit will run faster and more accurately if you gather the available information in advance. Nothing needs to be tidied up beforehand — the value of an audit is precisely that it records the real state of affairs.

• Whatever infrastructure documentation, diagrams and equipment lists you have — even incomplete ones;
• Contracts with IT vendors, internet, telephony, business systems and cloud service providers;
• A list of licences and subscriptions, or at least the invoices it can be reconstructed from;
• Contacts of the people responsible — who knows the passwords today, who administers each system;
• A list of known problems: what breaks most often, what employees complain about;
• A decision on who from management will take part in discussing the results.

What you receive: report, risks, priority plan

A well-executed audit delivers three things. First, a state-of-play report: what was found in each area, backed by facts rather than generalities. Second, a risk assessment: which findings pose a real threat to business continuity or data security, and what scale of damage is possible. Third, a priority plan: what to fix immediately, what to address in the near term, and what can wait for a planned upgrade. That plan becomes the foundation for both your budget and the conversation with your current or future support partner.

Backups and recovery scenarios deserve particular attention in the report — how they should be organised is covered on the page Backups and business continuity.

The ITIL and COBIT context: what the assessment is measured against

For an audit to be more than a subjective opinion, the assessment needs a frame of reference. In practice this is usually ITIL (IT service management good practice — incident, change and problem management) and COBIT (an IT governance framework linking IT processes to business goals and risks). Altic IT manages client IT estates according to ITSM, ITIL and COBIT good practice, and draws on the TOGAF architecture framework in consulting work — so audit conclusions are formulated in the same language used later for day-to-day IT management. If the audit surfaces deeper architecture or strategy questions, we continue the work through IT consulting.

Why Altic IT

An audit is best entrusted to a team that manages many different IT estates every day and knows what a well-run environment looks like — from practice, not theory.

• 180+ clients served, around 3,500 computers and mobile devices and around 350 servers under management — we benchmark findings against broad real-world practice;
• ISO 27001 (information security), ISO 20000 (IT service management) and ISO 14001 certifications;
• Professional liability and cyber risk insurance of EUR 2 million;
• A team made up predominantly of experienced senior-level IT specialists, with a seasoned external IT manager assigned to every client;
• Automated inventory and continuous systems monitoring mean audit conclusions are grounded in data;
• The vast majority of our clients came through referrals — among them the Bank of Lithuania, the State Tax Inspectorate, Bite Lietuva and MV Group.

If after the audit you decide to entrust us with day-to-day operations as well, we deliver them through our IT support services, and help close security gaps through our IT security services.

Frequently asked questions

• How long does an IT infrastructure audit take?

  The duration depends on the type of audit, the size of the company, the number of systems and the depth of the review. A narrower check takes less time, while a comprehensive audit including process assessment takes longer. We agree a concrete timeline before starting, once the scope is clear.

• Will the audit disrupt our operations?

  No. Most information is gathered by reviewing documentation and configurations and by using automated inventory and other audit tools that disturb neither employees nor the running of the IT systems. Interviews with responsible staff are scheduled at times convenient for them.

• Can you audit an IT estate managed by another vendor?

  Yes, this is one of the most common scenarios. It is worth bearing in mind, though, that an existing vendor will not assess its own work objectively, so the audit is carried out either by an independent auditor engaged by the company or by the incoming provider, for whom recording the current state is an essential part of the takeover. What matters is that your company has the right to obtain access credentials and documentation — something every IT services contract should provide for.

• How does an IT infrastructure audit differ from a security audit?

  A security audit looks only at protection against threats and the state of cyber security, whereas an IT infrastructure audit can cover far more: infrastructure, licences, processes, integrations, documentation, backups and access. Security is one of the areas examined. If your primary goal is NIS2 compliance, we tilt the audit scope towards security and governance requirements.

• What should we do with the audit results?

  The report sets out the current situation together with a priority plan: critical work, near-term work and planned upgrades. You can implement it with your own team, with your current vendor, or entrust it to us — the plan is written so it can be executed by any of these routes.
