Third-party risk comes in many forms – sometimes its cyber risk, sometimes it is operational. Just think about the risk that abounds as we recover from interruptions in traditional supply chains. Images of container ships idled offshore, unable to dock and unload their cargo to an economy eager to consume it, are a reminder of that risk. Third-party risk from your suppliers and channel partners intensifies the risk to first parties (your employees and users) and second parties (your customers).

Now think about your digital supply chain and the website that has become the heartbeat of your business. You can control your first-party risk through governance and the defenses you put in place against attacks. You manage second-party risk by encrypting the sensitive data your customers entrust to you. But how are you mitigating third-party risk in your digital supply chain? Have you even thought about it yet? 

In the traditional supply chain, you’re only as secure as the contractors, service providers, resellers and other partners you work with. In the digital supply chain, the same holds true. You’ve likely had many a conversation on third-party risk over the past year – but if you are like your peers, you may have overlooked an area that many of the world’s largest companies have yet to address. The client-side supply chain requires the management of third-party risk from JavaScript servers and information systems you may have never heard of before. If that isn’t risky, what is?

Third-party risk in your digital supply chain – Worse than idled container ships

Whether you operate an online storefront; are part of the hospitality and global ticketing market that is poised for massive growth post pandemic; or you operate a financial institution or a healthcare practice that has seen a major shift to online over the past two years, your website is an integral part of how you do business. Just as you’re vulnerable to disruption in the traditional supply chains that move merchandise, you’re also vulnerable to attacks on the digital supply chain that moves sensitive data. Those attacks happen outside of what traditional web security protects and they can go on for months without detection.

Your digital supply chain is just as crucial to your website, as container ships is as crucial to the traditional supply chain.

The code your website uses to capture and process data from your customers depends on JavaScript. Features like web forms and shopping carts call JavaScript from sources all over the internet, but how much do you really know about those sources?

Formjacking and digital skimming are two kinds of attacks introduced by third-party JavaScript on your website. When your customers enter their personal information and credit card numbers, you capture the data, but so does the malicious actor who sneaked the exploit onto your site through your partners.

Naturally, you focus on data governance and chain of custody when you share data with third-party vendors in your traditional supply chain. What about the third-party risk in your digital supply chain? Shouldn’t you focus on the risk from JavaScript running on your site that can send customer information to bad actors?

Those idled container ships may cost you in orders, but web app client-side attacks on your site will cost you in damage to credibility, reputation, customer goodwill and in potentially massive fines for things like GDPR policy violations.
