Trust but Verify: The Importance of Secure Vendor Management

When business owners think about cybersecurity, the focus usually lands on internal systems such as passwords, antivirus software, and firewalls. But what about the companies that help keep your business running? Your accounting firm, marketing agency, and cloud storage provider all interact with your data in some way.

If one of those vendors experiences a data breach or fails to maintain proper security controls, your business could be exposed as well. In fact, some of the largest breaches in recent years began through trusted third-party connections.

The Hidden Risks of Third-Party Vendors

Every vendor relationship introduces a new connection point, and every connection point is a potential doorway for attackers.

A vendor that uses outdated software, stores client data in an unsecured cloud environment, or neglects to patch vulnerabilities can unknowingly become an entryway for cybercriminals. Even something as simple as a shared login or an unsecured file-sharing platform can create serious exposure.

Small and medium sized businesses face higher risks because many depend on vendors for website hosting, payroll, and financial reporting. These relationships, while efficient, expand the attack surface and make it easier for bad actors to find weak spots.

Why Vendor Due Diligence Matters

Just as you would not hand a stranger a master key to your office, you should not give vendors access to your systems without knowing how they protect your data.

Vendor due diligence means taking the time to evaluate security practices before and during your business relationship. Here are a few best practices to keep in mind:

• Check for past data breaches. A quick online search can show whether a company has experienced previous incidents.

• Review certifications. Look for SOC 2, ISO 27001, or similar compliance standards that show accountability.

• Ask about authentication. Multi factor authentication and strong password policies are essential safeguards.

• Expect transparency. Reputable vendors will provide details about their security posture when asked.

Vendor management should never be a one time activity. It requires ongoing attention to ensure your partners continue following safe and modern cybersecurity practices.

Assessing Vendor Security Without Direct Access

Not every business has the ability or authorization to perform in depth scans of vendor systems. However, there are still effective ways to evaluate security from the outside.

Consider these approaches:

• Review website security such as SSL certificates, expired plugins, or configuration issues.

• Monitor public vulnerability disclosures for the products and tools your vendors rely on.

• Stay informed about breach announcements or reports that may affect your supply chain.

At Innosoft Engineering, the focus is on helping organizations better understand their external risk landscape. By examining website security, publicly available data, and email practices, it becomes easier to identify potential areas of exposure and strengthen overall awareness.
