Cybersecurity for Construction Firms: Protecting Your Business and Projects
Construction companies face growing cybersecurity threats. From ransomware attacks that halt operations to data breaches that compromise project information, cyber incidents can devastate construction businesses. This guide covers the cybersecurity landscape for contractors and practical steps for protection.
Why Construction Is a Target
Construction companies are attractive targets for several reasons:
Valuable Data
- Project plans and specifications: Sensitive infrastructure details
- Financial information: Banking data, payment records, employee data
- Client information: Owner data and business relationships
- Competitive intelligence: Bid pricing and strategy information
Operational Vulnerabilities
- Distributed operations: Job sites with inconsistent security
- Multiple systems: Fragmented technology environment
- Third-party access: Subcontractors, vendors, and consultants
- Legacy systems: Older software without security updates
Perceived Weak Security
- Limited IT resources: Many contractors lack dedicated IT security staff
- Focus elsewhere: Security competes with core business priorities
- Lower awareness: Construction not traditionally focused on cyber risk
Common Cyber Threats to Construction
Ransomware
The Threat: Malicious software encrypts your files and systems, demanding payment for restoration.
Impact on Construction:
- Project files inaccessible
- Estimating and billing systems locked
- Operations halted until resolved
- Ransom payments or costly recovery
Real World Example: A regional contractor lost two weeks of operations when ransomware encrypted their estimating system, project files, and accounting software. Recovery cost exceeded $200,000 even without paying ransom.
Business Email Compromise (BEC)
The Threat: Attackers impersonate executives, owners, or vendors to redirect payments or steal information.
Common Scenarios:
- Fake vendor payment requests with changed banking information
- Impersonated executives authorizing wire transfers
- Spoofed owner emails requesting sensitive information
- Hijacked email threads with fraudulent instructions
Real World Example: A subcontractor changed their banking information via email. Criminals had intercepted the email, altered the account numbers, and forwarded it to the GC. Two payments totaling $180,000 went to fraudulent accounts.
Phishing Attacks
The Threat: Deceptive emails trick employees into revealing credentials or downloading malware.
Construction-Specific Phishing:
- Fake bid opportunity notifications
- Spoofed plan room login pages
- Fraudulent vendor invoices with malware attachments
- Impersonated project management platform alerts
Data Breaches
The Threat: Unauthorized access to sensitive business and project information.
Compromised Data Types:
- Employee personal information (SSN, banking)
- Client financial data
- Confidential bid pricing
- Project designs for sensitive facilities
Job Site Technology Risks
The Threat: Connected devices and systems at job sites create security gaps.
Vulnerable Systems:
- Site WiFi networks
- Security cameras and access systems
- Connected equipment and sensors
- Shared project computers

- Communication procedures
- Recovery procedures
Recovery: Business Continuity
Backup Strategy
- Regular automated backups
- Off-site/cloud backup copies
- Backup encryption
- Regular restoration testing
Continuity Planning
- Critical system identification
- Recovery time objectives
- Manual procedures for key functions
- Communication plans
Practical Steps for Contractors
Start Here: Essential Actions
Immediate Priorities:
-
Enable MFA everywhere: Email, accounting, banking, project management—any system with login requires multi-factor authentication
-
Implement quality backups: Automated daily backups, stored off-site or in cloud, with regular testing of restoration
-
Train your people: Regular security awareness training covering phishing, password security, and safe computing
-
Update systems promptly: Patch operating systems and software quickly; enable automatic updates where possible
-
Secure email: Implement spam filtering and email security; establish procedures for verifying payment changes
Operational Security
Job Site Security:
- Separate networks for site operations vs. guest access
- Secure project computers with updated software
- Physical security for site technology
- Clear policies for personal device use
Remote Work Security:
