How far in advance should we start preparing for a security audit?

Begin preparation at least two to four weeks before the engagement start date. This gives your team time to gather documentation, update network diagrams, confirm asset inventories and coordinate schedules with internal stakeholders.

What documentation do we need to provide for a security audit?

At minimum you should provide current network diagrams, an asset and IP address inventory, a list of in-scope applications and URLs, any existing security policies and previous audit reports. For grey box or white box testing you may also need to provide credentials and architecture documentation.

How to Prepare Your Company for a Security Audit

A structured checklist to maximize the value of your security assessment.

Preparing for a security audit requires gathering network diagrams, building a complete asset inventory, defining the testing scope, setting testing windows, notifying stakeholders and backing up critical systems. Proper preparation ensures the assessment covers your highest-risk areas and delivers actionable findings.

The value of a security audit depends heavily on how well your organization prepares. Incomplete asset lists, outdated network diagrams and unclear scope definitions lead to gaps in coverage and wasted time. This checklist ensures you get the most from your investment.

Preparation Checklist

Seven Steps to Audit Readiness

1. Gather Network Diagrams

Collect current network topology diagrams that show how your systems interconnect. Include logical and physical network maps, firewall placement, DMZ architecture, VPN connections and cloud environment layouts. If your diagrams are outdated this is the time to update them. Accurate diagrams help testers understand your environment quickly and focus on the highest-risk areas rather than spending billable hours mapping infrastructure that you already understand.

2. Build Your Asset and IP Inventory

Create a comprehensive list of all assets in scope. This includes servers, workstations, network devices, cloud instances, web applications, APIs, mobile applications and IoT devices. For each asset document the IP address or URL, operating system, primary function and data classification. An accurate asset inventory prevents systems from being missed during testing and ensures coverage across your full attack surface.

3. Define the Scope

Work with your security provider to define what is in scope and what is excluded. Scope should be driven by risk: prioritize systems that handle sensitive data, process financial transactions or face the public internet. Be explicit about any systems that must not be tested such as legacy systems that may be fragile or third-party infrastructure you do not own. Clear scope definition prevents misunderstandings and ensures testing time is spent on the systems that matter most.

4. Set Testing Windows

Determine when testing can occur. Some organizations prefer testing during business hours so their security team can monitor in real time. Others prefer off-hours testing to minimize user disruption. For production environments establish maintenance windows for any high-risk testing activities such as denial-of-service validation or exploit attempts that could affect system availability. Communicate these windows clearly to all stakeholders.

5. Notify Stakeholders

Identify and brief all stakeholders who need to know about the engagement. This typically includes your IT security team, network operations, application owners, cloud administrators and executive leadership. Designate a primary point of contact who can authorize scope changes and receive critical findings in real time. For organizations with managed security providers or SOC services notify those teams to prevent the testing from triggering incident response escalations.

6. Back Up Critical Data

Perform full backups of all in-scope systems before testing begins. While professional testers design engagements to avoid disruption, backups provide a safety net for rapid recovery if an unexpected issue occurs. Verify that backup restoration procedures work correctly. This step is especially important for database servers, domain controllers and any systems where data loss would have significant business impact.

7. Establish Communication Channels

Set up secure communication channels between your team and the testing team. Define how critical findings will be reported, what contact methods will be used for urgent issues and how frequently status updates will be provided. Many organizations use encrypted email, a shared Slack channel or a dedicated phone line. Clear communication protocols prevent confusion during the engagement and ensure critical vulnerabilities are addressed promptly.

For grey box or white box testing you may also need to provide credentials and architecture documentation.
Do we need to back up our systems before a security audit?: Yes. While professional testers design engagements to avoid disruption it is a best practice to perform full backups of all in-scope systems before testing begins. This ensures rapid recovery if an unexpected issue occurs during the assessment.
