A general contractor in Hamilton, Ohio lost $187,000 last spring to a payment redirect scam that started with a spoofed email to the project accountant. The email looked like it came from a drywall subcontractor requesting an updated bank routing number for an upcoming draw. It wasn't caught until the actual subcontractor called asking why they hadn't been paid. This is the pattern showing up across construction firms in Butler County right now, and most of them are running IT setups built for a decade-old business model: one office network, a shared drive, and job-site laptops nobody has touched since they were issued.
Construction has a structural cybersecurity problem that doesn't get talked about the way it does in healthcare or finance. Projects run through a chain of general contractors, subcontractors, architects, and suppliers, all exchanging bids, change orders, and payment information over email. Every one of those handoffs is a phishing opportunity, and business email compromise (BEC) targeting construction payment workflows has become one of the most common fraud vectors in the industry — not because contractors are careless, but because the workflow itself has no built-in verification step. A managed IT services partner that understands this workflow can put controls around it: email authentication (DMARC/SPF/DKIM), payment change verification procedures, and monitoring that flags anomalous forwarding rules or login attempts from unfamiliar locations.
Job Sites Are Unmanaged Networks
Most construction firms in Hamilton run project management, estimating, and accounting software from a main office, then extend access to job trailers through consumer-grade routers or mobile hotspots nobody configured with any real security policy. Superintendents and project managers connect laptops and tablets to whatever Wi-Fi is available on site — sometimes their own, sometimes a subcontractor's, sometimes an open network at a job site trailer that's been sitting unchanged since the project started. There's no segmentation between the network carrying payroll and accounting data and the network a random subcontractor's laptop is sitting on.
Proper wireless networking for a job site isn't complicated, but it requires actually being designed: separate SSIDs for internal staff versus visiting trades, VLAN segmentation so a compromised device on the guest network can't reach the accounting system back at the office, and centrally managed access points instead of consumer routers bought at a big-box store. Combine that with structured cabling in job trailers for anything that needs a reliable wired connection — plan review stations, time clock terminals — and you eliminate a lot of the ad-hoc network sprawl that makes these environments hard to secure or even monitor.
Equipment Theft and the Case for Surveillance
Copper wire, tools, and heavy equipment theft from job sites costs the construction industry an estimated $1 billion a year nationally, and Hamilton-area contractors aren't exempt. Beyond the direct loss, equipment theft delays projects and drives up insurance premiums. Networked video surveillance — Avigilon or Axis systems with analytics that flag after-hours movement, paired with access control on material storage and trailers — gives project managers remote visibility into a site without a guard shack, and gives insurers documentation that reduces premium disputes after a loss.
Estimating and Project Data Deserves Real Backup
Whether a firm runs Sage, Foundation, or a general accounting platform layered with a construction PM tool, that data — bids, contracts, change orders, lien waivers — has real legal and financial weight, and it's often stored on a single server or a handful of laptops with no tested recovery plan. A ransomware event that locks up active project files during a draw schedule doesn't just cost money to recover from; it can trigger payment delays that ripple through every subcontractor on the job and expose the GC to breach-of-contract claims. Backup and disaster recovery built on Veeam, with backups tested and verified rather than just scheduled, is the difference between a bad week and a project that never recovers its schedule.
Email and Endpoint Security Aren't Optional Anymore
Given how much of the fraud risk in construction runs through email and how many endpoints are out in the field unmanaged, this is an industry where managed cybersecurity — SentinelOne EDR on every laptop and tablet, Huntress MDR watching for the kind of lateral movement that follows a successful phish, and SIEM logging tied to the office network — pays for itself the first time it stops an incident rather than responds to one. Layered with Microsoft 365 security features like conditional access and multi-factor authentication on every account that touches payment approval, a construction firm closes off the exact path that $187,000 walked out through.
Hamilton's construction firms are competing for tighter margins and faster schedules than they were five years ago. IT infrastructure that was fine for a smaller, single-site operation doesn't scale to multi-project, multi-subcontractor work without becoming a liability.
