An IT infrastructure audit surfaces the vulnerabilities, bottlenecks, and outdated dependencies that slow your business down before they become outages. Here is what triggers one and what to expect.
Most businesses schedule an IT infrastructure audit after something breaks. That is the wrong trigger.
An audit conducted after an outage is forensics. An audit conducted before one is insurance and it costs considerably less. The Canadian Centre for Cyber Security recommends proactive security assessments as a baseline practice for any Canadian business.
What an IT Infrastructure Audit Covers
A structured audit examines every layer of your technology environment:
Network and connectivity
- Firewall configuration and firmware versions
- Switch and AP hardware age and end-of-life status
- VPN configurations for remote access
- Internet redundancy and failover capability
Server and storage infrastructure
- Physical and virtual server inventory
- Backup configuration and last successful restore test
- Storage capacity, performance, and RAID health
- Operating system patch levels
Endpoint management
- Patch compliance across workstations and laptops
- Endpoint protection coverage gaps
- Hardware age and warranty status
- Encryption status on portable devices
Cloud and Microsoft 365
- License assignment and active user reconciliation
- MFA enforcement status
- Mailbox and SharePoint retention policies
- Admin account hygiene
- Password policy enforcement
- Privileged access review
- Security event log monitoring
- Third-party vendor access
The Five Triggers That Should Prompt an Audit
1. You have not had one in 18 months
Infrastructure ages faster than most businesses realize. A hardware lifecycle review alone is worth the exercise identifying equipment approaching end-of-life before it fails on a Friday afternoon.
2. You are onboarding a new IT partner
Before any managed service agreement starts, both parties should have a documented baseline. An audit protects the incoming partner from inheriting undisclosed problems and protects you from disputes about what existed before the engagement began.
3. You have experienced a security incident
Even a contained incident a phishing email that was caught, a suspicious login that turned out to be an employee is a signal that your current security posture has gaps worth examining.
4. You are about to sign a cyber insurance policy
Underwriters are increasingly requiring documented security controls as a condition of coverage. An audit produces exactly the evidence they need and surfaces gaps you can close to lower your premium.
5. Your business has grown significantly
Adding staff, locations, or systems without a corresponding infrastructure review is how technical debt accumulates. An audit after a period of growth resets your baseline and identifies where the seams are showing.
What a Good Audit Produces
A well-executed infrastructure audit should produce:
- An asset inventory every network device, server, and endpoint documented with version and warranty status
- A risk register vulnerabilities ranked by severity and likelihood
- A remediation roadmap prioritized by business impact, not just technical severity
- A cost estimate what it will take to address critical and high items in the next 12 months
The output should be written in plain language. If your audit report requires a full-time IT staff member to interpret, it is not useful to the business.
How Long an Audit Takes
For a company with 20–100 employees and a single location:
- Scope definition and scheduling: one to two business days
- Data collection and tool-based scanning: two to four business days (minimal disruption to operations)
- Analysis and report preparation: three to five business days
- Findings review session: 90-minute meeting with your leadership team
Total elapsed time: two to three weeks.
What It Costs
For most small and mid-size businesses in Metro Vancouver, an infrastructure audit by a qualified managed service provider runs $2,500–$6,000, depending on environment size and complexity.
Some MSPs offer a free or reduced-cost assessment as part of an onboarding evaluation. SFS Technologies offers a complimentary technology assessment for companies considering a managed IT engagement. The assessment covers the same ground as a paid audit and includes a written summary at no charge.
Starting the Conversation
If your business is overdue for a review or if something in this article sounded uncomfortably familiar the right next step is a brief discovery call. We will ask about your environment, your team size, and your current pain points.
From there, we can scope an assessment that makes sense for your situation.
