Cyber Liability Insurance for Auto Parts and OEM Suppliers
Your outage does not stop your plant, it stops your customer’s assembly line, and the charges that follow are contractual. Cyber Insurance Group has agents dedicated to cyber liability, comparing supplier coverage across 12+ A-rated carriers.
Compare your supply operation across 12+ A-rated carriers in about 4 minutes. Free, no obligation, and no need to know your limits in advance. We are an independent agency, so the recommendation is based on what covers your risk, not on one carrier’s product sheet.
Get My QuoteYour Downtime Is Measured on Someone Else’s Line
Just-in-time removed the inventory that used to sit between an incident at a supplier and a problem at an assembly plant.
Hours, not days
An assembly plant consumes your parts continuously. A recovery time that reads as reasonable internally can be far past the point your customer stops building.
Charges you agreed to
Line-stoppage provisions in your supply agreement create a bill that arrives regardless of cause, and sits outside most cyber business interruption wordings.
Customer design data
CAD models, tolerances and program timing belong to the OEM, live on your engineering network, and are shared onward to your own suppliers.
Requirements without budget
Security terms arrive through purchase orders and supplier manuals, with audit rights attached and no corresponding increase in piece price.
Your Lost Production Is Covered. The Line-Down Charge May Not Be.
This is where auto suppliers most often discover a gap, and it is discoverable in advance with one question.
What business interruption pays
Cyber business interruption is built to replace the income your operation lost during a covered incident, plus the extra expense of recovering faster. It is calculated on your production and your margin.
What a line-down charge is
It is a sum you committed in your supply agreement to pay when you fail to deliver and your customer’s line stops. Because it flows from a promise you made rather than from damage the attacker inflicted, most wordings sit it outside the business interruption calculation. For a sole-source supplier it can be the largest single number in the entire event.
There is no automotive DFARS
Defense suppliers get their requirements from federal contract clauses with defined deadlines. Automotive suppliers get theirs from customer purchase orders and supplier manuals. The obligations are just as real and just as enforceable, but they are commercial rather than regulatory, which means they vary by customer and are negotiated rather than published.
What is actually at risk, by what you make
- Defense and aerospace suppliers: what is really at risk is the government’s controlled unclassified information, and your eligibility to hold contracts at all.
- Chemical manufacturers: what is really at risk is formulations and process data, with no federal chemical security program being enforced since 2023.
- Medical device manufacturers: what is really at risk is the product itself, in a patient, under a statutory duty to keep it secure after it ships.
- Auto and OEM suppliers: what is really at risk is your customer’s production line, and the contractual charges that follow when it stops.
Why it changes the policy conversation
Compare three things before comparing premium: how the wording treats contractual penalties, how the waiting period is measured against your customer’s tolerance, and whether dependent business interruption reaches your own sub-suppliers. Our data breach response guide walks through the sequence.
Built for an Outage Measured in Hours
Your lost production
Business interruption and extra expense respond to output you could not make and the cost of recovering faster.
Your own suppliers
Dependent business interruption responds when a sub-supplier or logistics provider is the point of failure rather than your plant.
Customer data you held
Third-party liability responds when OEM design or program information is exposed through your systems.
Extortion against production
Cyber extortion coverage responds where an attacker holds manufacturing execution or quality systems rather than office files.
Before You Decide
The objections we actually hear from business owners, answered straight.
Does cyber insurance pay OEM line-down charges?
Often not, and it is the most important question a tier supplier can ask. Cyber business interruption replaces income your business lost. Line-down or line-stoppage charges are amounts you agreed in your supply agreement to pay your customer when you fail to deliver. Most wordings treat that as a contractual liability you accepted rather than loss the attacker caused. Ask the carrier in writing before binding.
Why would an attacker target a parts supplier rather than the automaker?
Because the leverage is better and the defenses are thinner. A tier two or tier three supplier may have a fraction of an automaker’s security budget while being a single point of failure for a component that an assembly plant consumes every few minutes. Pressure to pay comes from the customer, not just from the lost production.
Our OEM sent us a security requirement. Is that enforceable?
It is enforceable as a contract term, which is the practical answer. There is no automotive cybersecurity statute for US suppliers the way defense work has DFARS clauses. What there is instead is a cascade of customer requirements flowing down through purchase orders and supplier manuals, and increasingly the right to audit against them.
Does just-in-time delivery change our exposure?
It removes the buffer that used to absorb an incident. With little finished inventory between you and the assembly line, an outage measured in days becomes a customer problem within hours. Recovery time objectives that look acceptable on paper are often far too slow once you measure them against how fast your customer consumes your parts.
What about the design data we hold for our customers?
It is frequently the most valuable thing on your network and the least protected. CAD models, tolerances, tooling designs and program timing belong to your customer, are commercially sensitive, and are usually shared across engineering workstations and suppliers of your own. Exposure there is a third-party liability problem rather than a production one.
What does cyber liability insurance not cover for an auto supplier?
It does not pay line-down charges or contractual penalties, it does not replace tooling or equipment, and it does not cover a warranty or quality dispute. It responds to the incident itself: the forensic work, your own lost production, extortion, and claims arising from customer data you held.
What Would Cyber Liability Insurance Cost Your Supply Business?
Pricing follows production value per hour, whether you are sole-source on any part, what your supply agreements commit you to, and the controls you can evidence. See the breakdown in our cost guide, or get a number for your operation.
