Cybersecurity in the Construction Industry: What You Need to Know

Cybercriminals target the construction industry more often than ever. Cloud-based project management platforms, connected jobsite equipment, and remote collaboration tools improve efficiency. Unfortunately, they’ve also increased the number of potential cyber threats, like phishing or social engineering attacks. While the numbers may appear daunting, a solid data protection strategy can help you avoid becoming a part of negative stats.

The Cost of a Security Breach in the Construction Industry

Construction companies, by nature, maintain a high volume of sensitive information:

• Architectural drawings
• Company financial information
• Financial records
• Contracts
• Personally identifiable information (PII)
• Payroll information

Firms also work with various subcontractors, vendors, and clients. If a cybercriminal manages to steal your company’s data, it could start a chain reaction that will cost many companies money, reputation, and time.

Experts estimate that construction cyber attacks cost firms 24 days of work per year. A successful attack can halt operations, delay projects, and expose non-disclosure agreements crucial for your company’s future.

The Most Common Cyber Threats Facing Construction Firms

You need to understand the most common construction firm cyber threats:

Phishing Attacks

Cyber criminals create fake emails, websites, and text messages. They do this to convince employees to complete an action. A phishing email may ask an employee to provide sensitive information. Or, to click on a link that downloads malicious software. The sender often poses as a manager, client, supplier, or customer.

Recipients can spot phishing attacks through:

• Poor spelling
• Unexpected requests
• Urgent language
• Unfamiliar addresses

Ransomware Attacks

Ransomware is a type of malicious software spread through phishing emails. Once downloaded, the software prevents access until the firm pays a ransom. A ransomware attack can halt project schedules and lock access to blueprints.

Ascendant Technologies Inc. reported a 23% increase in ransomware and phishing attacks in June 2025.

Business Email Compromise (BEC)

BEC is when a scammer gains access to a legitimate company’s email and uses it for fraudulent means. For example, they could change your bank passwords or redirect invoices. 74% of businesses experienced BEC in 2025.

Weak Remote Access Security

In construction, employees can work from a different location every day. They access company data, accounts, and software using public and unsecured networks. Attackers can gain access and steal data through these networks.

Steps Construction Firms Must Take to Protect Their Operations

Cybersecurity doesn’t have to be difficult to be effective. By taking the following steps, firms can safeguard themselves from security breaches.

Build a Security-First Culture

Leaders of construction firms need to take cybersecurity seriously. They need to establish clear security policies and assign accountability.

They also need to ensure that employees understand how to protect company data.

Protect Remote Jobsites

Employees access company systems from temporary offices, public Wi-Fi, and mobile hotspots. Remote job sites often lack enterprise-grade security, leaving them vulnerable to cyber attacks.

Modern building firms counter the problem by using VPNs (Virtual Private Networks) to secure internet traffic. A VPN encrypts your internet traffic, making it difficult for hackers to intercept it and steal company data.

If you have never used a VPN before, you may be wondering, “what is a vpn protocol?” Each VPN comes with different levels of compatibility and speed based on the tool’s protocol. It’s the rules that dictate how the tool routes and encrypts data between the device and the VPN server. By choosing services with the most advanced protocols, you will avoid connection disruptions that can suspend your workflows.

Train Employees

Human error can create security incidents. All employees should be able to:

• Spot phishing emails
• Verify payment requests
• Report suspicious activity
• Safely use remote connections

Secure Third-Party Access

Construction companies work with many third parties. Each third party needs a different level of access to software and systems.

Providing minimal access is best for cybersecurity purposes. You should only provide access to what each employee needs to complete their job.

Keep Software Up-To-Date

Software goes out of date. Developers identify and fix system weaknesses, and patch things up through updates.

Managers must download updates as soon as they become available.

Cybersecurity Is Essential to the Construction Industry

In the coming years, construction companies will continue adopting digital technologies. Construction firms need to integrate cybersecurity as a core part of business practices. Digital tools help improve collaboration, productivity, and management. However, unsecured tools can create new opportunities for cybercriminals.
