What to Do When a Third-Party Vendor Experiences a Data Breach

When you hear about a data breach, you might breathe a sigh of relief knowing it wasn’t your business—but have you considered what happens if it’s one of your vendors? Sometimes the most significant risks to your business aren’t caused by internal issues but by external partners who experience cybersecurity problems. Let’s walk through the risks and actions you should take to protect your business if one of your vendors is compromised.

The level of threat depends on the type of vendor involved. For example:

1. Low-Risk Vendor: If a vendor that prints your business cards experiences a breach, it’s likely not a significant issue for you. They probably don’t have sensitive information about your business.
2. High-Risk Vendor: If a vendor handles your customer data or financial details, a breach could mean big problems. The fallout might affect your clients and your business reputation.

Start by gathering information:

1. What kind of breach occurred?
2. Was it caused by an internal issue, like human error, or an external attack, such as hacking?
3. What systems or data were compromised?

Understanding the breach’s scope will help you respond appropriately and gauge the potential impact on your business.

Take a close look at the relationship between your business and the vendor:

1. Shared Data: What data have you shared with them? Is it client information, financial records, or operational details?
2. Shared Clients: Do you and the vendor share the same clients? If so, the breach might extend beyond your business to your customers.
3. Sensitive Knowledge: Does the vendor know confidential details about your operations or strategies?

The more critical the data they have, the more urgent your response should be.

If the breached data ends up in the wrong hands, what could happen?

For example:

1. Direct Risks: If a vendor that manages your passwords, such as a password manager, is compromised, attackers could gain access to all your accounts.
2. Indirect Risks: If client data is exposed, it could harm your relationships and reputation.
3. Wider Impacts: Competitors or malicious actors might use stolen information to their advantage.

Understanding the worst-case scenario can help you prioritize your next steps.

It’s also essential to determine if your business is vulnerable to the same threat:

1. Do you use the same software as the vendor?
2. Was the breach caused by an unpatched security flaw, or were they using outdated systems?
3. Could this breach reveal gaps in your own cybersecurity practices?

Addressing these questions can help prevent similar issues within your organization.

Look back at any recent dealings with the vendor:

1. Have you opened files or clicked on links from them? These could be infected with malware.
2. Double-check account numbers on invoices to ensure they haven’t been altered—this is a common fraud tactic after breaches.

Be proactive in verifying the legitimacy of communications and transactions.

Once you’ve assessed the situation, it’s time to act:

1. Secure Your Systems: Update your software and apply security patches to close any vulnerabilities.
2. Change Passwords: If the vendor managed credentials or passwords, update them immediately.
3. Monitor Activity: Keep an eye on your accounts, networks, and client interactions for unusual activity.
4. Communicate Clearly: Inform stakeholders, including employees and clients, if they might be affected.
5. Consult Experts: Work with cybersecurity professionals to audit your systems and improve your defenses.
