What is the most common cybersecurity mistake architecture and engineering firms make?
The most common mistake is treating BIM and CAD project data as ordinary files instead of protected intellectual property. Architecture and engineering firms often leave large model repositories broadly accessible, skip access controls on shared drives, and reuse credentials across projects, which lets ransomware or a single third-party credential leak quietly expose an entire portfolio of client work.
What security-awareness training do architecture and engineering staff need?
Architecture and engineering staff need training focused on phishing recognition, credential hygiene, and safe handling of BIM and CAD project data shared with outside consultants. Because many incidents start with insider mistakes or third-party credential leaks, drafters, project managers, and principals should learn to verify file-transfer requests, enable multi-factor authentication, and report suspicious access, especially where NIST, DFARS, or California rules apply.
Is CAD and BIM software secure by default for engineering firms?
No, CAD and BIM software is not secure by default; it prioritizes collaboration and file sharing over protection. Architecture and engineering firms must add access controls, encryption, backups, and multi-factor authentication themselves, since default settings rarely meet NIST or DFARS expectations. Without those layers, shared model files stay exposed to ransomware, insider errors, and third-party credential leaks across the project team.
What does cybersecurity for architecture and engineering firms need to protect?
Last updated October 1, 2026 · HD Tech, serving Orange County since 1995
Cybersecurity for architecture and engineering firms needs to protect three things: the design files that represent years of work, the fee payments that move by email, and the personal and client data you're legally responsible for. That means MFA, monitored workstations and servers, email security, and backups ransomware can't reach. HD Tech builds those into every Orange County package.
Design firms sit in the middle of large projects, trading drawings and invoices with owners, contractors, and consultants every day, and attackers use that traffic. The FBI's 2025 Internet Crime Report counted 24,768 business email compromise complaints with about $3.05 billion in reported losses, and any firm that bills by email is exposed to the same scheme.
Paul Morton, CISSP, leads HD Tech's cybersecurity practice. The goal is to make it harder on the bad guys at each step without adding friction to production.
What Does Cybersecurity Cost for Architecture & Engineering Firms in Orange County?
HD Tech publishes its rates. Security is built into all four flat-rate packages rather than sold as an add-on, so the price below is the whole cost — monitoring, detection and response, and email security included from the entry tier up. Every package is month-to-month.
24/7 monitoring and SOC access, managed detection and response, conditional access management, email security, patch management, security awareness training.
Everything in Lifeline plus unlimited help desk, dark web monitoring, immutable backup, vulnerability scanning.
Watch Tower coverage plus managed on-premise servers, cybersecurity consulting, and server backup and disaster recovery. Help desk not included.
Everything in HQ Essentials plus unlimited help desk, server management, IT roadmap and budgeting, quarterly business reviews.
Rates are per user, per month. Monthly account minimums of $1,000–$2,000 apply, so a very small office pays the minimum rather than the per-seat rate — the price calculator gives your exact monthly cost. Rates last verified .

Plain-English Communication
No jargon, no tech-speak. We explain risks and solutions in language your team can understand and act on.
Who targets architecture and engineering firms, and how?
Four risks deserve the most planning at a design firm:
Ransomware on the project server. Encrypting the server that holds central models and archives stops production on every active job at once.
Fee and invoice fraud. A compromised mailbox, yours or a client's, is used to send new bank instructions in the middle of a real billing thread.
Credential theft on shared platforms. Consultants, contractors, and owners log in to Autodesk's cloud, SharePoint, Egnyte, and Bluebeam Studio, and one reused password can expose a whole project.
Departing-employee theft. Drawings, detail libraries, and proposals copied to a USB drive or personal cloud account on the way out the door.
None of these need a sophisticated attacker. They depend on missing MFA, flat file permissions, and nobody watching sign-ins after hours.
Which regulations and contract terms apply to A&E firms?
There is no cybersecurity law written specifically for architects and engineers, but several obligations commonly apply:
California's breach notification law (Civil Code 1798.82) requires notifying California residents whose unencrypted personal information is acquired in a breach, including employee data such as Social Security numbers. Breaches affecting more than 500 residents also require a sample notice to the Attorney General.
Federal design work. Firms handling Controlled Unclassified Information on DoD contracts must meet NIST SP 800-171 under DFARS 252.204-7012, and CMMC under 32 CFR Part 170 applies to primes and subconsultants that handle FCI or CUI as it phases into DoD contracts.
Client agreements. Owners, developers, and public agencies may add confidentiality, security, and breach-notification terms to design contracts, and those can be stricter than any statute.
Insurance. If you carry cyber insurance, answer the application's security questions accurately and keep those controls in place.
What security controls should a design firm have in place?
MFA on Microsoft 365, Autodesk Account, Egnyte or SharePoint, remote access, and banking.
Managed detection and response on every workstation and server, watched 24/7.
Project-based permissions, so staff and consultants see only the jobs they work on, with access removed at closeout or departure.
Immutable or offline backups of project servers and archives, tested with full-project restores. CISA recommends offline, encrypted backups because many ransomware variants look for and destroy reachable backups.
Alerts on mass downloads and copying to USB or personal cloud storage.
Callback verification for any change to payment instructions, received or sent.
Phishing training for principals, project managers, and drafters alike.
Every HD Tech package includes 24/7 monitoring, managed detection and response, email security, patch management, and security awareness training. The Watch Tower and above add a 24/7 SOC, dark web monitoring, immutable backup, and vulnerability scanning, and HQ Essentials adds cybersecurity consulting, which can help with written policies and client security questionnaires.
Frequently Asked Questions
How do we protect design files when an employee leaves for a competitor?+
Plan for it before anyone gives notice. Limit each person's access to the projects they work on, log file access on the project server, and alert on mass downloads or copying to USB and personal cloud accounts. When someone resigns, review recent activity, disable accounts on their last day, reclaim their Autodesk seat, and collect every company device. Your employment agreement covers the legal side; IT supplies the evidence.
Do architecture and engineering firms on military projects need CMMC?+
If your DoD contract or subcontract involves Federal Contract Information or Controlled Unclassified Information, expect it. The DFARS rule implementing CMMC took effect November 10, 2025 and is phasing in, the required level appears in each solicitation, and primes must flow it down to subconsultants. Firms handling CUI must also meet NIST SP 800-171 under DFARS 252.204-7012. Our government contractor page covers the details.
How should we share drawings with outside consultants securely?+
Use a managed platform such as Autodesk's cloud, SharePoint, Egnyte, or Bluebeam Studio instead of email attachments or personal file-sharing links. Invite consultants per project, require MFA where the platform supports it, set shared links to expire, and remove access at closeout. That also gives you a record of who downloaded what, which a client may ask for after an incident.
What backup protects a Revit central model from ransomware?+
One that ransomware can't encrypt or delete: immutable cloud storage or an offline copy, kept separate from the credentials that run your network. Back up the central file with its links, families, and project folders together, and keep multiple versions so you can restore to a point before the attack. Test by restoring a complete project and opening it in Revit.
What should we do if a client says they never received our payment?+
Treat it as a possible email compromise. Call the client at a number you already have to confirm what bank details they received and when. If money went to the wrong account, both parties should contact their banks immediately to request a recall and file a complaint at ic3.gov. Then check mailboxes for forwarding rules and unfamiliar sign-ins, reset passwords, and notify your insurer.
How much does cybersecurity cost for an architecture or engineering firm?+
HD Tech's packages are flat-rate per user and month-to-month, with security built into every tier. Pricing starts at $85 per user per month, monthly minimums apply, and the full rate table appears on this page. Firms that need written policies, help answering a client security questionnaire, or an incident response plan can add standalone cybersecurity consulting.
