Cybersecurity for Manufacturing that Keeps Production Running
Manufacturer cybersecurity in four takeaways
Attackers seek out targets with high stakes and multiple blind spots, and manufacturing has both. Distributed sites, legacy systems that can’t go down, remote access into plants, and blurry lines between IT and OT.
Trusted tools make good cover. Remote monitoring and management (RMM) abuse jumped 277% year over year and showed up in 24% of all incidents Huntress observed last year.
Valid logins open doors without malware. Ransomware showed up in 5% of incidents, and about 17% of those attacks showed identity threat warning signs at least seven days before deployment.
The window is there if someone’s watching. Time-to-ransom rose from 17 to 20 hours, and ClickFix drove 53% of malware loader activity.

Cyber attacks in manufacturing: what our SOC sees first
1. Remote access can become the path to disruption
277%
year-over-year increase in RMM abuse, which appeared in 24% of all incidents
Vendor RMM agents run on machines near production and have broad local admin rights. Over time, RDP, VPNs, OEM portals, and RMM pile up with no inventory and no single place watching them. That crowd of tools gives attackers cover.
2. Identity compromise can reach production without malware
37%
of identity threats. Mailbox manipulation and persistence (19%), adversary-in-the-middle (19%), and malicious OAuth and app abuse (10%) follow.
Cloud identities now run email, MES, ERP, PLM, and supplier portals. Access is shared across engineering, plant, quality, and finance. Shared mailboxes and service accounts get less attention than people's accounts. A stolen login doesn't need malware to reach production data.
3. Social engineering targets operational workflows
53%
of malware loader activity started with ClickFix
Different tricks, same goal: get a person to do the attacker’s work for them. ClickFix gets people to run the attacker’s code themselves. Business email compromise (BEC) uses a trusted name and a believable request. SEO poisoning puts bad downloads at the top of search results. AI helps attackers write cleaner lures and mimic voices and faces, so old red flags like typos don’t help as much.
4. Ransomware disruption starts earlier than most teams think
17%
of ransomware incidents showed identity warning signs at least seven days before deployment. Nearly 21% showed them within 14 days.
Ransomware showed up in 5% of incidents in 2025, though volume is still up. The bigger story is what comes first. Once encryption starts, time-to-ransom is now 20 hours, up from 17. For a plant, that means halted lines, locked order and inventory data, and finance and logistics disruption that can last weeks. Attackers may also steal CAD files, specs, pricing, and supplier contracts before they ever encrypt anything.
Meeting insurer, customer, and compliance requirements
If you build for defense customers, CMMC and NIST 800-171 are probably already on your list. Insurers and large customers also ask for proof that your controls work. Huntress supports those conversations with 24/7 monitoring, logging, and incident-response records that an auditor can read.
We help you show your work. We don't make you compliant on our own, and your requirements depend on your contracts.
The Huntress Platform
How Huntress protects manufacturing operations
Huntress gives your team a 24/7, human-led AI-centric SOC watching your endpoints, identities, and email, so you don’t have to. When we spot a threat, our analysts investigate, contain, and walk you through cleanup. You can also set the platform to remediate automatically.
Cyber threat concern | Huntress Protection | Outcome |
Rogue remote tools and vendor access | Unexpected tools and suspicious “support activity” get investigated and contained | |
Stolen logins and inbox abuse | Odd sign-ins, hidden forwarding rules, and risky apps get caught and removed | |
Evidence for insurers, customers, and auditors | Logs and 24/7 SOC monitoring, in one place | |
Phishing, ClickFix, BEC, deepfakes, and poisoned search results | Your whole team learns to spot the lure, verify the request, and report it before it becomes an incident | |
Loose Microsoft 365 and identity settings that make stolen logins easier to use | Your Microsoft 365 and identity settings get hardened and kept that way, managed and enforced by Huntress experts |
Huntress protects the IT side of your operation: endpoints, identities, email, and the remote access that attackers use to get in. That's where attacks on plant environments often begin. We don't monitor OT networks or replace segmentation, so pair us with OT-specific monitoring and network controls where you need them.

Real teams, real results
How an MSP caught a manufacturer's hidden email leak in 20 minutes
The CEO of a large manufacturing company had no idea his email was compromised. A hidden forwarding rule had been quietly sending his messages out, possibly for months. Within 20 minutes of rolling out Huntress, the SOC caught it, reset the account, and removed the rule.

Featured Case Study
Two people in IT, seven Microsoft 365 tenants, two weeks to deploy
A fast-growing roofing and exterior company kept adding brands through acquisitions, and its IT team was a sysadmin and a VP. Huntress was running across seven Microsoft 365 tenants and 600 endpoints in two weeks. When an employee clicked a malicious link, the sysadmin got an alert almost instantly, and Huntress had already contained it.
"Time: that's my ROI." — System Administrator and Cybersecurity Lead
600 endpoints · seven Microsoft 365 tenants · two weeks to deploy
Not a manufacturer, but a close match if you run multiple sites, grow through acquisition, and have a small IT team.
Manufacturing cybersecurity FAQs
Downtime hurts, and attackers know it. An idle line means late shipments and penalty clauses, which creates pressure to pay fast. Manufacturers also hold CAD files, specs, and pricing that attackers can steal for extra leverage. Ransomware appeared in 5% of incidents in Huntress data, but it's the loudest end of a longer attack.
Start with an inventory of every RDP path, VPN, OEM portal, and RMM agent, and who owns each. Remove what you don't use, limit vendors to what they need, and require MFA. Then have someone watch for unexpected remote tools. Huntress Managed EDR flags suspicious support activity and rogue tools.
If you make parts or products for defense customers, or sit in that supply chain and handle controlled unclassified information, probably yes. Requirements depend on your contracts, so check with your contracting officer or a compliance advisor. Huntress supports your efforts with monitoring, logging, and incident response data. Read our CMMC Level 2 guide.
Look for 24/7 human-led investigation, not just alerts. Look for coverage across endpoints and identities, since attackers move between them. Look for containment and cleanup, not a pile of tickets. Then ask who responds at 2 a.m., how fast, and whether they can show real examples from customers like you.
Quickly. A roofing and exterior company went live with Huntress across seven Microsoft 365 tenants and 600 endpoints in two weeks. Your timeline depends on how many sites and tenants you have and how your team rolls out software. Start a free trial or book a demo, and we'll help you map it.
Teach people to pause and verify, not just look for mistakes. Attackers now use AI to write clean emails and fake voices, so confirm urgent requests through a second channel. Managed SAT gives your whole team, including contractors, short, engaging courses on these tricks.
