Why your vendors may be your biggest risk
As we celebrate independence this July, it’s a timely reminder that in cybersecurity, real independence comes from knowing your systems aren’t vulnerable due to someone else’s weaknesses. Third-party vendors, whether they’re software providers, data processors, or logistics partners, often have direct or indirect access to your systems and data. When these partners lack strong security practices, they can become a gateway for attackers to infiltrate your organization. In fact, supply chain attacks have been on the rise precisely because cybercriminals see vendors as soft targets with access to much larger ecosystems.
How to reduce risk in your supply chain
Protecting your organization starts with visibility. Conducting thorough due diligence before bringing on any vendor is crucial. This includes reviewing their security policies, ensuring they follow industry best practices like encryption and multi-factor authentication, and confirming compliance with relevant standards (such as SOC 2). Once a vendor is onboarded, periodic reviews should follow to monitor for changes in their posture, especially after any public breach or operational change.
Another key step is to build security into your contracts. Make sure your agreements include specific language about data protection responsibilities, breach notification timelines, and audit rights. If a vendor is unwilling to meet these requirements, that’s a red flag. Internally, implement access controls to limit what each vendor can reach within your environment, and separate critical systems from third-party access wherever possible.
Stay vigilant, stay secure
No matter how trusted a vendor is, unchecked access or a lapse in their practices can quickly become your organization’s problem. Supply chain risk isn’t always obvious, but the consequences of ignoring it can be severe. Take time this month to assess your vendor relationships and tighten up your controls. Independence from insecure vendors starts with knowing exactly who you’re trusting and verifying that they’re up to the task.
