Why is wire fraud such a big problem in construction?

Because the industry moves large, scheduled payments among many parties. Attackers monitor a compromised inbox, wait for a real payment, and send convincing updated banking details. The FBI's IC3 consistently ranks business email compromise among the costliest cybercrimes.

How do we protect data across jobsites and subcontractors?

With segmented, secured jobsite connectivity, MFA and least-privilege access to project systems, encryption of drawings and bids, and clear data-handling rules for the partners and subs you share files with.

Do construction firms have compliance obligations?

Often, yes. Federal and defense work brings NIST SP 800-171 / CMMC requirements; California's CCPA/CPRA applies to personal data you hold; and large owners increasingly flow down contractual security and breach-notification clauses.

How do we prevent fraudulent payment changes?

Adopt a firm rule that any change to banking or payment instructions is verified by phone to a known number before funds move — never using contact details from the email itself — backed by MFA and email authentication to make impersonation harder.

Cybersecurity for Construction & Engineering Firms Across Every Jobsite

General contractors, architects, and engineering firms — juggling sensitive bid data, multi-site networks, and large payments that fraudsters love.

// In brief

Construction firms move large payments on predictable schedules, which makes them prime targets for business email compromise and wire fraud. (FBI IC3)
Bid data, drawings, and BIM models are valuable IP that's often shared loosely across owners, subs, and jobsites.
Temporary jobsite networks and a mobile workforce expand the attack surface well beyond the main office.

What makes it different

The risks unique toconstruction & engineering.

Large, scheduled payments invite wire fraud

Progress payments, draws, and vendor invoices move on predictable timelines, giving attackers clear opportunities to impersonate a party and redirect funds via business email compromise.

Project data is scattered and shared widely

Drawings, bids, and BIM models pass among owners, architects, engineers, and subcontractors, multiplying the places sensitive IP can leak or be intercepted.

Jobsite networks and mobile crews widen exposure

Temporary trailers, cellular routers, and personal devices on active sites rarely get enterprise-grade security, creating soft entry points into project and financial systems.

Compliance

The frameworks thatapply to you.

CMMC 2.0 & NIST SP 800-171 (federal projects)

Firms on federal or defense construction that handle Controlled Unclassified Information face the same NIST SP 800-171 / CMMC obligations as manufacturers.

CCPA / CPRA

California firms holding personal information of employees, clients, or homeowners must provide reasonable security and honor privacy rights, with breach liability for inadequate safeguards.

Contractual & Owner Security Requirements

Large owners, GCs, and public agencies increasingly flow down specific cybersecurity, data-handling, and breach-notification clauses that become binding contractual obligations.

Real threat scenarios

How attacks on construction & engineeringactually play out.

Wire fraud on a progress payment

Impact

An attacker impersonates a subcontractor or the GC and emails updated banking details, diverting a six- or seven-figure draw that is very hard to claw back.

How we defend

MFA, email authentication, and a strict out-of-band verification policy for any change to payment instructions.

Ransomware on project and design files

Impact

Drawings, schedules, and BIM models are encrypted mid-project, stalling work across every jobsite that depends on them.

How we defend

EDR/MDR, immutable backups, network segmentation, and a tested recovery runbook.

Bid-data theft

Impact

Sensitive pricing or proposal data is stolen and used by a competitor, undermining your bids and client trust.

How we defend

Least-privilege access, encryption, DLP, and monitoring of unusual file access before bid deadlines.

How we defend it

Three pillars, mapped toconstruction & engineering.

Ransomware Defense

MDR, email security, and immutable backups defend the payment workflows and project files attackers target.

Disaster Recovery

Tested recovery keeps a design-file outage from cascading across every active jobsite and blowing schedules.

Network Projects

Secure jobsite connectivity, segmentation, and MFA extend enterprise-grade protection to trailers and mobile crews.
