Construction Sector

Construction is increasingly a target for cyber attack.

Construction firms manage high-value project data, complex supply chains, and increasingly connected operational technology. From BIM models and tender documents to payment systems and site access controls, the attack surface is larger than many firms realise.

The threat landscape

Why construction firms are under threat.

The construction industry has undergone rapid digital transformation. Project management platforms, Building Information Modelling (BIM), cloud-based collaboration tools, and IoT-connected site equipment have all expanded the attack surface. At the same time, the sector's reliance on complex supply chains and subcontractor networks means that a single weak link can compromise an entire project.

Ransomware attacks on construction firms have increased significantly, with attackers knowing that project delays cost thousands per day and create pressure to pay. Business email compromise targeting payment processes between contractors, subcontractors, and clients remains one of the most financially damaging attack vectors. And with many construction firms now required to meet Cyber Essentials for government contracts, security is no longer optional.

Key threat areas

The risks facing your business.

Project Data Theft

BIM models, tender documents, architectural plans, and contract details are valuable to competitors and criminal actors. A breach can compromise commercially sensitive project information across multiple stakeholders.

Ransomware & Downtime

Encrypted project management systems and file servers bring operations to a halt. With project deadlines and contractual penalties at stake, construction firms face intense pressure to restore access quickly.

Payment Fraud

Business email compromise targeting payment processes between main contractors, subcontractors, and clients. Fraudsters intercept invoice communications to redirect payments to accounts they control.

Cyber risks

Threats specific to the construction sector.

Supply Chain Compromise

Construction projects involve dozens of subcontractors and suppliers, each with their own systems and access. A compromised supplier can provide a direct route into your network and project data.

Remote Site Connectivity

Construction sites rely on temporary network infrastructure, site cabins with VPN connections, and mobile devices. These remote environments are often less secure than the main office.

Cloud Collaboration Platforms

Project management tools, BIM platforms, and file sharing services used across multiple stakeholders create shared risk. Misconfigured access controls can expose project data to unauthorised parties.

Phishing & Social Engineering

Construction staff are frequently targeted with phishing emails impersonating subcontractors, suppliers, or project managers. High staff turnover and varied IT literacy increase susceptibility.

Weak Authentication & Access Controls

Shared credentials, lack of multi-factor authentication, and poor password practices are common across construction firms, leaving systems vulnerable to credential-based attacks.

Compliance & Contract Requirements

Government contracts and tier-one clients increasingly require Cyber Essentials certification and evidence of regular penetration testing as a condition of tender.

FAQ

Frequently asked questions.

Why are construction companies being targeted by cyber criminals?

Construction firms handle high-value project data, process large financial transactions between multiple parties, and often have less mature cyber security than other sectors. Attackers target the combination of valuable data, complex payment flows, and the operational pressure of project deadlines to maximise their chances of a successful attack or ransom payment.

Do we need Cyber Essentials to bid for government construction contracts?

Yes. Cyber Essentials certification is mandatory for government contracts involving the handling of sensitive or personal information. Many tier-one contractors also now require their supply chain partners to hold Cyber Essentials as a condition of working together. Achieving certification demonstrates a baseline level of cyber security and can open doors to new contract opportunities.

Can you test our remote site infrastructure?

Yes. We can assess remote site connectivity including VPN configurations, site cabin networks, and the security of connections between remote locations and your main office infrastructure. Testing can be performed remotely or on-site depending on the scope and your requirements.

How can we protect against payment fraud between contractors?

Payment fraud in construction typically relies on business email compromise, where attackers intercept or spoof invoice communications to redirect funds. A combination of network penetration testing to secure your email infrastructure, social engineering assessments to test staff awareness, and a review of your payment verification processes can significantly reduce this risk.
