Tell them that your product is built from hundreds of pieces of other people's code, and supply chain security is knowing what those pieces are and noticing when one becomes dangerous. It is the same idea as ingredient lists and supplier checks in a restaurant kitchen.
Start with the analogy
A restaurant does not grow every ingredient. It buys from suppliers and trusts them. If a supplier ships something contaminated, the restaurant is responsible to its customers. Software works the same way. Your app includes open source packages, build tools, container images and services written by others.
Supply chain security has three jobs. Know what is in the product. Notice when an ingredient has a known problem. Control who and what can change the product before it ships.
Why a founder should care
Your customers will ask. Security questionnaires often include questions about third party code, and buyers want a straight answer. A weak answer slows deals. A strong, specific one, such as we keep an inventory and review it monthly, helps them.
It is also a basic business continuity point. If a widely used package is found to be compromised, you want to know within hours whether you are affected, and not discover it from a customer.
What goes wrong, in three sentences
A package you use is found to have a flaw, and attackers use it. Or an attacker publishes a harmful package with a convincing name, and a developer installs it. Or someone gains access to your build process and changes what ships. The controls are different for each, which is why one tool rarely covers all three.
What it costs
Mostly time, not money. The first month takes a few hours a week from one engineer. Many of the basic controls are free features of tools you already use. The real cost is the engineer's attention, so decide what they stop doing.
The one page you can show
| Question a founder asks | Answer to give |
|---|---|
| What do we depend on? | A list we generate from our code |
| How would we hear about a problem? | Alerts go to one named owner |
| What stops a bad change reaching customers? | Required review and checks on the main branch |
| Who is responsible? | One named person with a backup |
| How do we know it works? | Four numbers reported monthly |
For the plan behind those answers, see the first week plan.
What you need from the founder
- Backing for the owner's weekly time slot.
- A decision on how fast known exploited issues must be fixed.
- Willingness to delay a release for a serious finding.
- Awareness of what customers have been promised, since promises become obligations.
What not to say
Do not promise that you are secure or that nothing can go wrong. Say that you have a process, you measure it and you improve it. Also do not claim certifications you do not hold.
CISA describes an SBOM as a nested inventory, a list of ingredients that make up software components, which is the same analogy in official language.
Safeguard helps with the inventory, the alerts and the gates. The free scan at https://gold.safeguard.sh/scan produces a founder friendly first list.
Quick check
Is supply chain security the same as cybersecurity?
It is one part of it. It focuses on third party code, build systems and delivery, while cybersecurity also covers networks, devices, people and more.
