Part of Advanced Networks’ Manufacturing IT Services in Los Angeles hub.
When a cyberattack hits a manufacturer, the damage isn’t measured in lost files — it’s measured in stopped production lines, missed shipments, idle workers, and customers who go elsewhere. A single ransomware event can freeze your ERP, halt the production floor, and cost tens of thousands of dollars for every hour the plant sits idle. Advanced Networks delivers cybersecurity built for the realities of manufacturing, protecting both your business systems and the equipment that keeps product moving.
For more than 20 years, we’ve secured Los Angeles and Orange County businesses as a top-ranked managed services provider, and we work with manufacturers across the LA basin — from Vernon and the City of Industry to Anaheim and beyond. We understand that in manufacturing, security and uptime are the same conversation, and we build programs that protect production without getting in its way.

Onsite and remote, anytime
Architected for uptime
Audit ready, always
The Advanced Shield™ platform keeps production running: endpoint protection on the floor, monitoring across OT and IT, and tested recovery so a cyber incident doesn’t become downtime.
Why manufacturers are increasingly under attack
Manufacturing has become one of the most-targeted industries for cyberattacks, and the reason is simple: manufacturers can’t afford downtime, which makes them more likely to pay a ransom to get the line running again. Attackers know this and have shifted their focus to the factory floor and the systems that run it.
The risk is amplified by how manufacturing technology has evolved. Production environments now blend traditional IT — ERP, email, file servers — with operational technology (OT) like PLCs, SCADA systems, CNC machines, and IoT sensors that were never designed with security in mind. Many of these systems run older, unpatched software and sit on the same flat network as everything else, giving an attacker who lands in one place the ability to reach the entire plant.
The pain points we see most often when assessing LA manufacturers include:
- Ransomware that stops production, encrypting the ERP and shared drives that schedule and track every job
- Flat networks where office PCs, the production floor, and management systems all share one segment
- Legacy and unpatched OT equipment that can’t be taken offline easily and rarely gets updated
- Vulnerable ERP and MRP systems — including SYSPRO, Epicor, and similar platforms — that hold pricing, inventory, and customer data
- Supply-chain and vendor risk, where a compromised partner or remote-support connection becomes the way in
- Weak endpoint protection on shop-floor terminals and shared workstations
If your plant is running on a flat network or aging OT, request a security assessment before an attacker finds the gaps first.
How Advanced Networks protects Los Angeles manufacturers
We secure manufacturing environments with a layered program that respects the constraints of a production operation. That means hardening IT and OT, segmenting networks so a breach in one area can’t take down the whole plant, locking down the ERP, and maintaining tested backups that can bring you back online fast. Everything is monitored 24/7 by a local team, with cybersecurity built into the service rather than sold as a separate line item.
Crucially, we design controls around uptime. We know you can’t simply reboot a CNC machine in the middle of a run or take SCADA offline for a patch window during peak production, so we plan changes around your schedule and prioritize controls that protect without disrupting throughput.
ERP and manufacturing systems security
Your ERP is the nerve center of the operation, and it’s a prime target. We secure platforms like SYSPRO, Epicor, and other MRP/ERP systems with strong access controls, encryption, server hardening, timely patching, and continuous monitoring for suspicious activity. We make sure the data that drives quoting, scheduling, inventory, and shipping stays accurate, available, and out of the wrong hands.
OT vs. IT security and network segmentation
Protecting a plant means treating operational technology differently from office IT — and keeping them apart. We map your environment, then implement network segmentation that isolates the production floor, OT systems, office network, and guest access from one another. If an office laptop is compromised by phishing, segmentation stops the infection from ever reaching the PLCs and machines that run production. We secure the boundaries with firewalls and intrusion detection so traffic between zones is controlled and watched.
Ransomware protection and production-downtime prevention
Ransomware is the threat most likely to stop your line, so we defend against it in depth: endpoint detection and response (EDR) on every workstation and server, 24/7 threat monitoring, disciplined patch management, email filtering to block the phishing that delivers most ransomware, and segmentation to contain anything that gets through. The goal is simple — keep the plant running and keep an incident from becoming a shutdown.
Endpoint and shop-floor device protection
Shop-floor terminals, shared kiosks, and warehouse devices are easy to overlook and easy to exploit. We deploy managed antivirus and anti-malware plus EDR across these endpoints, control which devices and USB drives can connect, and monitor for anomalies. Protecting the machines closest to production closes a gap most generic IT providers miss.
Backup, disaster recovery, and rapid restore
When prevention isn’t enough, recovery speed determines how much a breach costs you. We implement automated, encrypted, and immutable backup and disaster recovery covering your ERP, file servers, and critical configurations, with regularly tested restores. If ransomware or hardware failure strikes, we bring you back online in hours, not days — without paying a ransom.
Vendor and supply-chain security
Manufacturers are deeply connected to suppliers, customers, and equipment vendors who often need remote access for support. Each connection is a potential entry point. We secure third-party and remote-support access with strict controls and monitoring, evaluate vendor risk, and enforce multi-factor authentication so a compromised partner credential can’t become your breach. For manufacturers in the defense supply chain, we also support CMMC compliance requirements.

The advantage of a Los Angeles–based security partner
In manufacturing, a security incident can mean a stopped line, and a stopped line means you need help now — not a ticket waiting in an overseas queue. Advanced Networks is headquartered on Wilshire Boulevard in Los Angeles with a second office in Irvine, and our engineers are local. We respond in minutes and can be on the floor across LA and Orange County when an incident demands hands-on response.
A local partner also understands the Southern California manufacturing landscape — the suppliers, the compliance pressures, and the realities of running a plant in this region. We’ve supported LA-area manufacturers for years and know how to protect a production environment without slowing it down.
Case-study-style examples
Containing ransomware before it reached the floor. An LA-area metal-products manufacturer had an office workstation infected through a phishing email. Because we had segmented the network and deployed EDR, the infection was isolated to the office segment and never reached the production systems or ERP. The line kept running, and we restored the affected workstation from backup the same day.
Keeping the floor running. Like our long-time client Pacific Sintered Metals, where manufacturing IT and security keep the floor moving, a precision parts maker came to us with a flat network and aging endpoints. We segmented IT from OT, hardened the ERP, and added 24/7 monitoring — reducing risk substantially while ensuring none of the changes interrupted active production runs.
Recovering an ERP after hardware failure. When a server hosting a manufacturer’s ERP failed unexpectedly, our tested disaster recovery plan restored the system within hours. Scheduling, inventory, and shipping data came back intact, and the plant avoided what could have been days of costly downtime and manual workarounds.

Frequently asked questions
What does manufacturing cybersecurity in Los Angeles include?
It includes network segmentation of IT and OT environments, endpoint detection and response across office and shop-floor devices, ERP/MRP security, firewalls and intrusion detection, patch management, email security, multi-factor authentication, secure vendor access, and tested backups — all monitored 24/7. Advanced Networks delivers these as one managed program designed to protect production uptime.
Why are manufacturers such a frequent target for ransomware?
Because manufacturers can’t afford downtime. Attackers know a stopped production line costs thousands per hour, which makes manufacturers more likely to pay to restore operations quickly. Layered defenses, segmentation, and tested backups remove that leverage by keeping you running and able to recover without paying.
What’s the difference between IT and OT security?
IT security protects business systems like ERP, email, and file servers, while OT (operational technology) security protects the equipment that runs production — PLCs, SCADA, CNC machines, and IoT sensors. OT often runs older software that can’t be patched easily, so it requires different controls and, critically, network segmentation to keep it isolated from the rest of the environment.
How does network segmentation protect my plant?
Segmentation divides your network into isolated zones — production floor, OT, office, and guest — so a compromise in one area can’t spread to the others. If an office PC is infected through phishing, segmentation prevents the malware from ever reaching the machines and controllers that run production.
Can you secure our ERP system, such as SYSPRO?
Yes. We secure ERP and MRP platforms including SYSPRO, Epicor, and others with access controls, encryption, server hardening, timely patching, and continuous monitoring, so the data that drives scheduling, inventory, and shipping stays protected and available.
Will adding security controls disrupt our production?
No. We design controls around your operation, scheduling changes during planned windows and prioritizing protections that don’t interrupt active runs. Our goal is to protect uptime, not threaten it, which is why we plan every change with production in mind.
