Quick Answer: An IT security audit independently evaluates your organisation's information security controls, policies, and practices against frameworks including ISO 27001, SOC 2, NIST CSF, and Essential Eight. Deliverables include a risk-rated findings report, compliance gap register, and prioritised remediation roadmap.
What Is an IT Security Audit?
An IT security audit is a comprehensive, independent evaluation of your organisation’s information technology controls, policies, and practices. Unlike a penetration test (which focuses on active exploitation), a security audit provides a broader assessment of whether your controls are properly designed, consistently implemented, and effective at managing risk.
IT security audits are conducted for multiple reasons: regulatory compliance, internal governance, pre-merger due diligence, ISO 27001 or SOC 2 preparation, or simply to get an objective view of your security posture from an external expert.
What Does an IT Security Audit Cover?
Access Control Review
User access rights, privileged account management, identity lifecycle (joiners/movers/leavers), multi-factor authentication, and separation of duties across critical systems.
Network Security Assessment
Firewall ruleset review, network segmentation, VLAN configuration, remote access controls, VPN configuration, and wireless security.
Cloud Security Posture
AWS/Azure/GCP configuration review against CIS benchmarks — covering IAM policies, storage permissions, logging, encryption at rest and in transit, and network security groups.
Patch Management and Vulnerability Management
Review of patching processes, vulnerability scanning cadence, mean time to remediate (MTTR) for critical CVEs, and end-of-life software inventory.
Backup and Recovery Controls
Backup frequency, retention policy, offsite/cloud replication, recovery testing evidence, and RPO/RTO alignment with business requirements.
Incident Response Readiness
Incident response plan documentation, last tested date, escalation procedures, regulatory notification obligations (OAIC for Australia, CERT-In for India, SEC for public companies in the US).
Compliance Gap Analysis
Assessment against relevant frameworks: ISO 27001, SOC 2, NIST CSF, Essential Eight (Australian Government), CIS Controls, PCI DSS, or HIPAA — depending on your regulatory obligations.

Frequently Asked Questions
What is the difference between an IT audit and a penetration test?
A penetration test actively exploits vulnerabilities to demonstrate impact. An IT security audit reviews whether controls are in place, properly configured, and operating effectively — without active exploitation. Both are complementary: audit finds control gaps, pentest demonstrates exploitability.
How long does an IT security audit take?
Typically 2–4 weeks depending on organisational size, number of systems in scope, and framework alignment required. The report is usually delivered within 1 week of fieldwork completion.
Is the audit conducted remotely or on-site?
We conduct audits both remotely (via secure screen-sharing and document review) and on-site for clients requiring physical security assessment or where data sensitivity prevents remote review. We serve clients across the US, Australia, and India with both options available.
