Introducing PCI DSS support for cardholder data security

Check into your chosen firm’s availability. Small auditing firms tend to have more limited time and need more advance notice, while larger firms have more resources and, therefore, more availability. However, larger firms can cost more to hire.

Give yourself enough time before the audit. In many cases, audits don’t just check to see if you’ve done an activity once; they look for evidence of continuous controls. Plan to collect consistent evidence over at least three months to demonstrate this.

Choose a dedicated team or team member who will be available throughout the audit. Your auditor will need a go-to person to provide all the proper information and be available for any follow-up questions. Check calendars of others stakeholders involved with the audit controls  to ensure they’ll be present when you schedule your audit on-site or live sessions.

Be aware of commitments and deadlines. You will likely sign a statement of work (SOW) when you schedule an audit. Your team is responsible for meeting all the deadlines outlined in this SOW. The auditor will need the correct information from your team in a timely manner to do their job.

Know which framework(s) you’re working towards and communicate the requirements to your team. If you’re going to work towards multiple frameworks simultaneously, identify overlaps so you don’t duplicate work. A tool like Vanta helps break down requirements and map them to action items.

Understand which evidence each team needs to provide. Next, communicate requirements and deadlines to each department. It’s a good idea to use a central hub that can show all preparation activities and who is responsible for each one.

Inform your team why this is an important activity so they understand that the time and commitment are worthwhile for them. Connect it to outcomes and KPIs that matter to their teams whenever possible. Audits ultimately prove your company’s commitment to security and trust, and meeting a framework can be the difference between growing your business and missing out on opportunities.

Communicate to your team that the goal is progress, not perfection. If it’s your first time getting audited against a particular framework, you probably won’t get a perfect score, and that’s okay! Instead, make it your goal to set a baseline for meeting the framework, then find ways to improve your controls over time.  

Ensure your evidence shows consistency —not just point-in-time or static documentation. You should be able to prove that you’ve maintained the proper controls throughout your audit window. A tool like Vanta that supports continuous controls monitoring can help with this.

Compile and store your documentation in a way that simplifies sharing the relevant evidence with the auditor. You want to spend as little time as possible chasing down specific documents or screenshots during the audit. Getting organized beforehand means far less stress for your team when the auditor begins their assessment. Vanta can help you stay on top of your documentation by storing all documents in a centralized location and automatically updating data with real-time changes.

Get to know your evidence inside and out. You shouldn’t be surprised by anything that your auditor finds. It helps to use a governance, risk, and compliance (GRC) automation tool to parse through the documentation and summarize findings. This way, you have a consolidated view of evidence rather than a bunch of disparate documents and files that are hard to consume at once.

Be transparent and upfront with your evidence. Don’t try to shape a specific story or alter the truth by showing more or less documents to an auditor. Honesty is always the best policy in these cases, especially considering the potential consequences of lying in an audit. Altering the truth can significantly impact the integrity of your company, or even prevent you from requesting audits in the future.

Help your auditor understand your business. You will need to guide them through the ins and outs of your organization, including where your controls reside and which insights they provide to your business. They won't know where to start assessing your controls if they don’t understand your organization or GRC processes and tools.

Treat the audit like a conversation. In most cases, your auditor will be inside your organization for a few weeks to months, and during that time, it should become a back-and-forth working relationship. The auditor will likely ask you for specific evidence over time, and you will work with them directly to provide each piece of information they need, and so on.

Maintain the relationship with your auditor afterward. They can serve as a helpful resource as you build out your GRC initiatives and continuously maintain and improve compliance over time. While auditors can’t give direct advice on how to do something, most are more than willing to help wherever they can. For example, if you plan to change your tech stack, employee policies, etc., consider asking your auditor how these changes will impact future audits before committing to the change.

Track KPIs that show your response to the gaps that your auditor finds. The specifics of these KPIs will depend on your particular business, priorities, etc. In general, they should center around risk reduction and remediation efforts. For instance, if you have any findings, opportunities for improvement (OFI), or nonconformities listed in your report, track the response to these insights over time. How are you changing processes? What new tools have you implemented?

Consider conducting a readiness assessment between formal external audits. Businesses will typically either hire a third party or pick a team member who isn’t involved in any GRC activities to perform this type of audit. The best way to incorporate readiness assessments into your processes without causing business disruption is to use continuous monitoring to get an instant snapshot of all existing controls.

Treat your audit like a jumping-off point for security initiatives. Meeting a particular framework doesn’t necessarily equate to bulletproof security. For example, a compliance framework often doesn’t account for emerging threats. Still, consistently meeting the controls listed in a framework is a great starting point for establishing a strong security culture throughout your organization.

Foster a strong security culture. As you respond to your audit findings and implement stronger GRC controls, your team members need to understand why specific controls exist and how to play a role in meeting them. Ultimately, this is all about fostering a strong security and risk management culture throughout your organization. Consider rolling out security training and tracking KPIs such as phishing drill click-through rates and training completion rates. This will help demonstrate progress for future audits as well as improving your organization’s security posture.
