Incident Response Services for Dealerships
When an attack lands, one team contains it, gets your stores selling again and hands you the facts every notice will ask for. Live analysts watch around the clock, and the same people run your IT.
Incident response services for dealerships are the people who contain a cyberattack, find out what it touched, restore the systems your stores run on and give you the facts your insurer and regulators will ask for.

An Attack Stops the Store. Response Decides for How Long.
The call usually comes early in the morning. A salesperson can’t get into the DMS, the service advisors are writing repair orders by hand, and somebody in accounting has noticed that every file on the shared drive has a strange new name. Nobody’s sure whether to unplug things, call the insurance company or call the police first. Everybody looks at the GM. A 2023 study of dealership cybersecurity from CDK Global put the average downtime after an attack at 3.4 weeks, and a good share of what decides your own number happens in the first few hours.
At Helion Technologies, incident response is part of cybersecurity for dealerships, run by the people who already manage your network, your Microsoft 365 and your backups. Live, US-based analysts watch around the clock, investigate what they find and contain it when it’s real. Day or night. Still weighing why a written plan matters? Our post on the value of an incident response plan makes that case. This page is about the team that carries one out.
Every hour spent hunting for the right phone number is an hour the sales floor stays dark. Response is a team, not a binder.
Why Incident Response Services Belong With Your IT Team
We’ve watched the same thing happen at dealerships for years. The security vendor sees the alert, the IT provider owns the servers, a third company holds the backups and the DMS provider has its own support line, and once the attack is underway each of them is waiting for one of the others to call back. A security incident and an IT outage are usually the same event, described by two different vendors. That’s where the hours go.
Helion works differently. The analysts who contain the attack hand straight to the engineers who rebuild the server and the people who restore from your backup and disaster recovery copies, and nobody has to be briefed twice. Same people, start to finish. The best incident is the one caught before any files lock, which is the job of managed detection and response. When one gets further than that, the same people pick it up.
There’s one number to call, and nobody left to point a finger at.
Four vendors, four phone lines
The firewall company says the firewall’s fine, the backup company says the backups ran, and the controller is stuck in the middle relaying messages between them.
Meanwhile the deal desk sits idle.
One integrated team
When an auto group split from 8 stores to 3 and lost its entire IT team overnight, CIO included, Helion responded right away and rebuilt its IT from scratch.
The same team, whatever the emergency.
When it happens
What Incident Response Looks Like in the First 72 Hours
No two attacks play out alike, so read the sheet as the order the work tends to run in. Our side is on the left. The note on the right is the decision that stays with you, since a few of these calls belong to the dealer principal and never to an IT provider.
In the middle of one right now?
Pull the network cable on the affected computers and leave them switched on, which is what CISA’s ransomware guide advises, then open our incident response plan template and start at the top of page one.
The first 72 hours What our team does, and what you decide
Minute 0 An alert, or a phone call
It might be one of our analysts watching a server act strangely at 3 a.m., or a sales manager at 7:40 who can’t open the DMS. From the sales floor an attack and an ordinary outage look exactly alike. So the first thing anyone does is work out which one this is.
Decide now who at each store makes that call to us.
Hour 1 Contain it
Minutes count here. Infected machines come off the network, the accounts the attacker is using get locked and the way in gets shut, one store at a time if it has spread. We leave those machines switched on where we can, since the evidence of what happened is sitting on them.
Taking a whole store offline is your decision, and we’ll explain why we’re asking.
Hours 2 to 24 Find out what it touched
Which stores, which systems, which accounts, and whether customer records were copied out or only locked where they sit. That last question decides nearly every notice that follows, so it gets written down as we go. Guesses don’t hold up.
Call your insurer’s claims line early.
Hours 24 to 72 Get the store selling again
Order matters. Before anything comes back, the door the attacker used gets closed, or the store restores itself straight back into the same trouble. Then systems return from clean backups in the order the business needs them, so the desk can work deals and the service drive can print a repair order before anything else.
You decide what customers hear, and when.
Week 2 on Write it up and close the gaps
You get a written record of the timeline, what was affected and what was done about it, which is what your attorney, your insurer and any regulator will want to see. That record matters. The weak spots that let it happen get fixed, and the plan gets updated with what actually happened.
Notices run on their own clocks. The table below lists them.
After containment
Who Needs to Hear About It, and When
A breach at a dealership can owe notice to five or six different parties, each on its own deadline. None of them wait. Your attorney decides the filings. Our part is getting the facts each notice needs into your hands early enough to meet it.
| Who | When it applies | What you’ll need from the investigation |
|---|---|---|
| The FTC | Unencrypted information on 500 or more consumers was taken. Under 16 CFR 314.4(j) notice is due as soon as possible, and no later than 30 days after discovery | The number of consumers, the kinds of information involved and the date range of the event |
| Customers and state attorneys general | Every state has its own breach notice law, and the rules follow where each customer lives, not where the store sits. Many also require notice to the state attorney general | Affected customers sorted by state, with what was exposed for each |
| Your cyber insurer | As soon as you suspect an incident. Policies usually require prompt notice, and some only pay for the lawyers and forensics firms the carrier approves | When the first alert came in, what was contained and when, and the systems involved |
| Law enforcement | Any ransomware or extortion attempt is worth a report to the FBI through IC3 or your local field office. An official can ask in writing for public notice to wait | The ransom note, any contact details the attackers left and the timeline |
| Your OEM, floor plan lender and DMS provider | Whatever your agreements say. GM, for one, wants a confirmed incident reported within 72 hours | A short, factual summary you can send without guessing |
| The SEC, for public dealer groups | A material cybersecurity incident goes on Form 8-K, Item 1.05, generally within 4 business days of deciding it’s material | What happened, how far it reached and its likely effect on operations |
A summary, not legal advice. The SEC’s 2023 disclosure rule and the FTC’s Data Breach Response guide set out the details, and our page on Safeguards Rule breach notification walks through the FTC form. State rules are mapped in dealership privacy laws by state, and OEM windows in OEM cybersecurity requirements. For the full federal playbook, see NIST’s incident response guide, SP 800-61 Rev. 3.
The Team That Picks Up the Phone
We’ve worked only with car and truck dealerships since 1997. That’s all we do. In an incident that matters more than it sounds, because the systems in the middle of it, the DMS integrations, the OEM portals, the F&I tools and the wireless in the shop, are ones our people already know. An outside responder spends the first day just learning your network. We don’t have to.
