Cybersecurity for engineering firms means protecting design files, client data and project systems from theft, ransomware and downtime. The most important steps are multi-factor authentication (MFA) and secure file sharing. Protected backups for large project files, managed devices and staff training complete the basics.
Engineering firms hold valuable intellectual property and work under tight project deadlines. A single ransomware attack can freeze CAD and BIM files for days. This guide explains why engineering firms are targeted and the biggest risks. It also lists the steps firms on Seattle’s Eastside and beyond should take.
Why are engineering firms targeted by cybercriminals?
Engineering firms store drawings, models, specifications and bids that can be worth a great deal to competitors and criminals. They also share files with clients, contractors and consultants, which creates many entry points. Project deadlines make firms more likely to pay to restore access quickly. Many small and midsize firms also rely on a few people to manage IT, so gaps go unnoticed.
What are the biggest cyber risks for engineering firms?
- Ransomware. Attackers encrypt CAD, BIM and project files and demand payment.
- Intellectual property theft. Designs and proprietary methods can be stolen and sold.
- Phishing and fake invoices. Criminals pose as clients, subcontractors or vendors to steal passwords or payments.
- Insecure file sharing. Large files sent through personal accounts or unprotected links can leak.
- Remote and job site access. Laptops and tablets used in the field can be lost or connected to unsafe networks.
- Outdated software. Older workstations and plug-ins can leave known security holes open.
What should engineering firm cybersecurity include?
Is MFA turned on everywhere?
Turn on MFA for email, cloud storage, project management tools and remote access. It blocks most attacks that rely on stolen passwords.
Are design files shared securely?
Use a managed file-sharing platform with access controls, link expiration and activity logs. Avoid personal file-sharing accounts and email attachments for sensitive drawings.
Are large project files backed up and tested?
CAD and BIM files are large and change often. Back them up frequently, keep at least one copy separate from your network and test that you can restore a full project quickly.
Are workstations and devices managed?
Keep operating systems, design software and plug-ins updated. Encrypt laptops and tablets used on job sites, and use device management so lost devices can be locked or wiped.
Is access limited by role and project?
Give staff and outside consultants access only to the projects they work on. Remove access when a project ends or someone leaves.
Are staff trained to spot scams?
Short, regular training helps staff recognize phishing emails, fake invoices and suspicious file-sharing links.
Do engineering firms need to meet security requirements for clients?
Many clients now ask about cybersecurity in contracts and questionnaires. Firms that work on U.S. Department of Defense projects may need to meet Cybersecurity Maturity Model Certification (CMMC) requirements. CMMC is based on NIST guidance for protecting controlled information. Public agencies and large clients may also require proof of controls such as MFA, encryption and backups. A managed IT provider can help you document these controls.
How can engineering firms protect remote and job site work?
Use a secure connection, such as a VPN or a managed remote desktop, for access to project files from home or the field. Avoid public Wi-Fi without protection. Keep field devices encrypted and updated, and store files in managed cloud storage instead of on the device.
What IT services do engineering firms need?
Beyond security, engineering firms rely on IT that can keep up with demanding software and large files. Useful IT services for engineering firms include:
- Help desk support for design and project software
- Workstation planning for CAD, BIM and rendering
- Fast, reliable networks and storage for large files
- Cloud collaboration tools set up with the right access controls
- License management for design software
- Technology planning and budgeting for upgrades
How should engineering firms manage vendors and subcontractors?
Outside consultants and subcontractors often need access to project files. Give them separate accounts with access only to their projects, and turn on MFA for every account. Use shared workspaces with expiration dates instead of sending files by email. Ask key vendors how they protect your data, and remove access as soon as their work ends.
How can firms protect bids and proposals?
Bids and proposals contain pricing and methods that competitors would like to see. Store them in folders with limited access, track who opens them and avoid sending drafts through personal email. Watch for fake requests for proposals and look-alike email domains, which criminals use to steal files or passwords.
How should engineering firms respond to a cyberattack?
- Disconnect affected devices from the network.
- Call your IT provider and your cyber insurance carrier.
- Tell clients about project delays if needed.
- Restore files from clean backups.
- Reset passwords and review how the attack started.
What else do engineering firms ask about cybersecurity?
Do small engineering firms need cybersecurity?
Yes. Small firms hold the same kinds of designs and client data as large firms, and they are often easier targets.
How much does IT support for engineering firms cost?
It depends on the number of users, workstations and services included. Many firms use a managed IT provider for a predictable monthly fee.
What is the first step?
Turn on MFA for email and file sharing, and make sure your project files are backed up and tested.
