According to IBM's Cost of a Data Breach Report 2024, the global average cost of a data breach reached an all-time high of $4.88 million this year – a 10% increase from 2023.1 But while businesses of all sizes need to prioritize their digital defenses, multi-location enterprises face some unique challenges when it comes to building cyber resilience.
Businesses operating across multiple locations depend on data distributed across various sites and systems, which increases the complexity of securing their IT infrastructure. In fact, 40% of data breaches in 2024 have involved data stored across multiple IT environments.1 Each additional location potentially introduces new vulnerabilities, making it crucial for these organizations to implement cohesive, company-wide cyber security measures.
One way to overcome this challenge is with a comprehensive IT audit. In this blog, we're sharing an IT audit checklist to help you maintain a resilient IT infrastructure across all your locations.
An IT audit is an evaluation of an organization's information technology infrastructure, policies, and operations. This assessment ensures that IT systems are secure and compliant with relevant regulations and industry standards. IT audits cover various areas, including hardware, software, networks, data management, and cyber security measures.
The main goal of an IT audit is to identify potential vulnerabilities, assess risks, and provide actionable recommendations for improvement. Regular IT audits help businesses address security gaps, optimize IT processes, and enhance overall operational efficiency.
In terms of cyber security, an IT audit plays an important role in strengthening an organization's digital defenses. It helps identify weak points in the security infrastructure, evaluate the effectiveness of existing security measures, and ensure regulatory compliance with industry-specific requirements like GDPR, HIPAA, or PCI DSS. By uncovering potential security risks before hackers exploit them, IT audits help prevent breaches and other cyber incidents.
IT audits encompass several areas that contribute to the security of your organization's IT infrastructure. A comprehensive IT audit checklist includes:
System security is the foundation of any IT environment. An IT audit should analyze the effectiveness of security controls protecting your systems, networks, and data from unauthorized access and other potential security threats.
Focus on evaluating:
Assessing these components will help you identify vulnerabilities in your system security and implement necessary improvements to strengthen your defense against cyber threats.
The number of cyber attacks using stolen or compromised credentials rose by 71% in 2023.2 User access controls are essential in preventing unauthorized access to sensitive information and systems. An IT audit should examine the processes and technologies used to manage user authentication, authorization, and accountability.
Key areas to evaluate include:
Examining your user access controls can help you determine who has access to your organization's data and systems, reducing the risk of internal and external data breaches.
Even the best technical controls can be undermined by everyday user actions. Recent industry reports attribute a majority of breaches to the “human element,” including phishing, credential misuse, and simple mistakes. An IT audit should therefore evaluate how your organization is preparing employees, contractors, and partners to recognize threats and follow security policies in their day-to-day work.
As part of the audit, assess whether your security awareness program is current, role-based, and delivered on a regular cadence. Look at how often users receive training, whether content covers real-world threats like phishing and social engineering, and how new hires are onboarded into security expectations. Check participation records and completion rates to confirm that training isn’t optional in practice, especially for high-risk roles such as finance, HR, and administrative access holders.
Beyond training completion, your IT audit should look at how your organization measures and reinforces secure behavior. This might include reviewing phishing simulation results, reporting rates for suspicious messages, and how repeat issues are addressed. The audit can also surface cultural friction points, such as teams feeling pressured to bypass controls to meet deadlines. Bringing these insights into the audit report helps leadership see security awareness as an ongoing business initiative rather than a one-time checklist item.
Effective performance monitoring can help IT teams maintain optimal system functionality and identify potential issues before they escalate. An IT audit should evaluate the tools and processes used to monitor IT infrastructure performance, including:
An evaluation of your performance monitoring practices can help you optimize your IT infrastructure, improve system reliability, and enhance overall operational efficiency.
The systems development lifecycle can significantly impact your technology infrastructure's security, functionality, and efficiency. An IT audit should examine the processes and controls in place for developing, testing, and implementing new systems and applications, including:
A thorough assessment of your systems development practices can help you identify areas needing improvement, strengthen your application security, and ensure your development processes align with industry best practices.
Disaster recovery and business continuity plans are vital for responding to an outage or cyber attack. And as 76% of organizations reported at least one ransomware attack in 2023,3 evaluating your organization's preparedness to recover from disruptions should be a priority during your IT audit.
Areas to assess include:
By evaluating your disaster recovery and business continuity preparedness, you can ensure your business is ready to face unexpected challenges and minimize potential downtime and data loss.
Proper documentation and audit reports can help your teams maintain transparency, accountability, and compliance across all IT operations. An IT audit examines your organization's practices for documenting IT processes, security policies, and incidents.
Key areas to evaluate include:
Evaluating your documentation and reporting practices will help ensure your company maintains accurate records, facilitates knowledge transfer, and supports compliance efforts.
Compliance with relevant industry regulations can help your business avoid legal issues and maintain stakeholder trust. An IT audit should evaluate your organization's adherence to applicable compliance requirements.
Areas to assess include:
Reviewing your regulatory compliance practices will help your organization avoid potential legal and financial consequences while building trust with customers and partners.
Modern IT environments depend on cloud platforms, SaaS applications, managed service providers, and telecom carriers. An IT audit should map which external partners can access your data or systems and how they connect to your environment. Recent breach reports show that attacks frequently involve third-party infrastructure or software supply chains, so understanding this extended attack surface is now a core audit requirement, not a nice-to-have.
Your audit should also review whether third-party contracts and service-level agreements clearly define security, uptime, incident notification, and data-handling expectations. Ask for current attestations or certifications where appropriate, such as SOC 2, ISO 27001, or industry-specific frameworks. The goal is to confirm that vendors’ controls align with your own regulatory obligations and internal policies, especially when they handle sensitive or regulated information on your behalf.
Lastly, consider how vendor sprawl affects your risk profile. Managing dozens of local contracts and point solutions across locations makes it harder to enforce standards and monitor performance. As part of the IT audit, identify opportunities to consolidate providers or centralize contracts, particularly for network and telecom services. A smaller, more strategic set of partners can simplify governance and make it easier to maintain consistent controls across every site.
Physical security measures are often overlooked in IT audits, but play a crucial role in protecting your IT assets. An IT audit should assess the measures in place to secure physical access to your organization's IT infrastructure, including:
Assessing your physical security controls can help identify potential vulnerabilities in your IT infrastructure's physical protection and implement necessary improvements to safeguard your assets.
While an IT audit typically takes place over several days, the entire process begins well in advance. Conducting an IT audit involves:
The first decision is whether to conduct an internal IT audit or hire an external auditor. Large corporations and companies that handle sensitive data often opt for external audits, while most businesses find internal audits sufficient and more cost-effective. Some organizations choose to conduct yearly internal audits and bring in an external IT auditor every few years for an additional perspective.
Some key planning considerations include selecting the IT auditor, determining the audit timeline, and establishing processes to prepare employees for the audit. Schedule the audit when your staff isn't overwhelmed with other responsibilities, as IT auditors will need to speak with various employees and team managers to understand your company's workflows.
Once you've established a general timeframe, work with your IT audit team to prepare for the audit itself. During this stage, you'll need to determine the audit scope, objectives, documentation methods, and a detailed audit schedule. This includes deciding which departments will be evaluated on which days and for how long.
Consider using an IT audit checklist to ensure you've covered all necessary aspects during the planning phase. This preparation will help ensure a smooth audit process that allows you to identify and address potential issues more effectively.
This step involves executing the plan you've created. However, it's important to be prepared for unexpected challenges. Build in extra time to address any issues that arise without compromising the thoroughness of the audit.
During the IT audit, the team will review documentation, interview key personnel, observe IT operations, and perform technical evaluations and testing. This comprehensive approach allows IT auditors to gain a deep understanding of your organization's IT environment, processes, and potential vulnerabilities.
After completing the IT audit, compile your auditor's notes, findings, and suggestions into an official audit report. This will serve as a reference for future audits and help plan improvements.
Create individual audit reports for each audited department, including:
Outline the next steps to address the identified risks. In cases of willful carelessness, consider involving the HR department to address personnel-related concerns.
Many infrastructure vulnerabilities stem from human error, which can also affect the implementation of solutions. After delivering your report, it's crucial to schedule follow-up dates with each team to ensure the successful implementation of corrections. This step helps maintain accountability and ensures that the audit findings are being addressed effectively.
Plan periodic check-ins throughout the year to maintain smooth operations until the next IT audit. These follow-ups provide an opportunity to assess the effectiveness of implemented solutions and make any necessary adjustments.
Most organizations benefit from a comprehensive IT or security audit at least once per year. For multi-location enterprises or highly regulated industries, more frequent targeted audits, such as semi-annual or quarterly reviews of critical systems, can help keep pace with evolving risks and infrastructure changes. Your IT audit program should define which areas are reviewed annually and which require a more frequent review.
In addition to routine audits, build in event-driven audits to follow significant shifts in your environment. Examples include adding new locations, migrating workloads to the cloud, rolling out major applications, or experiencing a security incident or prolonged outage. These focused audits help you validate that new deployments align with your standards and that corrective actions after an incident are working as intended.
Automation and continuous monitoring can provide near real-time visibility into performance, vulnerabilities, and configuration drift between formal audits. Use these tools to reduce the manual effort required for data collection and to identify issues early, then feed those findings into your next scheduled or event-driven audit. The result is a more proactive audit program that balances structured reviews with ongoing oversight.
Implementing automation in your IT audits can streamline the process and deliver real-time insights into your organization's IT infrastructure.
Start by setting up dashboards to automatically track and report key performance indicators (KPIs). These dashboards will allow you to measure the impact of changes implemented after your initial audit. When you conduct follow-up assessments in the months following your audit, use these reports to evaluate performance and address any issues that aren't meeting expectations.
Implementing automated vulnerability scans and continuous system performance monitoring can further enhance your audit process. Instead of relying solely on manual check-ins and periodic reviews, let your technology do the heavy lifting. Set up alerts that notify your IT teams of potential issues or anomalies, allowing you to focus your attention where it's most needed.
Leveraging automation tools can help you:
Remember that while automation can improve your IT audit procedures, it shouldn't completely replace human oversight. Use these tools to augment your team's capabilities so they can focus on performing more complex analyses.
IT audit services provide an independent review of your technology environment, including infrastructure, security controls, policies, and processes. The goal is to confirm that your systems are secure, compliant, and aligned with your business objectives, not just running “well enough” on the surface. A well-run IT audit helps you uncover risks, optimize investments, and build a roadmap for future improvements.
A comprehensive IT audit typically examines system security, access controls, performance monitoring, systems development, disaster recovery and business continuity, documentation and reporting, regulatory compliance, and physical security. For multi-location enterprises, it should also include asset and endpoint management, third-party risk, and security awareness practices to give you a complete picture of your posture across all sites.
Most businesses should plan for a full IT or security audit at least once a year, and more frequently for high-risk or highly regulated environments. In addition to that annual cadence, it’s wise to trigger smaller, targeted audits after major changes such as cloud migrations, new locations, or significant incidents. This combination of scheduled and event-driven audits helps you stay ahead of new risks.
An IT auditor reviews documentation, interviews stakeholders, and performs technical tests to evaluate how your systems are designed and operated. They compare current practices against policies, standards, and regulations; identify gaps or inconsistencies; and then summarize their findings in a report with prioritized recommendations. Their role is to provide an objective view of your IT environment so you can make informed decisions.
During an IT audit, your disaster recovery and business continuity plans are evaluated to confirm they are current, realistic, and regularly tested. The auditor will look at backup strategies, recovery time objectives, failover capabilities, and incident response procedures. This helps ensure your organization can restore critical systems quickly and continue serving customers even when disruptions occur.
Internal IT audits are carried out by your own teams or a dedicated internal audit function and focus on continuous improvement and adherence to your policies. External audits are performed by independent third parties who validate your controls against external standards, regulations, or customer requirements. Many organizations use both: internal audits for ongoing oversight and external audits for additional assurance and stakeholder confidence.
You can streamline future IT audits by maintaining accurate documentation, keeping asset and configuration inventories up to date, and standardizing processes across locations. Implementing monitoring and automation tools can also reduce manual data collection and provide auditors with clear, consistent reports. When your environment is well-documented and your teams know what to expect, each audit becomes faster, less disruptive, and more focused on meaningful improvements rather than basic fact-finding.
Conducting a comprehensive IT audit can help businesses identify vulnerabilities, assess risks, and provide actionable recommendations across various aspects of their IT infrastructure. For enterprises operating across multiple locations, this process is necessary to ensure a cohesive and robust security posture across all sites.
