Quick Answer: Cyber Insurance for Engineering Firms

Engineering firms handle sensitive client data — blueprints, structural designs, project bids, and client financials — making them prime targets for ransomware and data breaches. Cyber insurance typically costs $1,200–$3,500/year for firms with under 50 employees.

Best carriers for engineering firms:

Hartford: Broad cyber + professional liability bundles, strong mid-market pricing
Chubb: Premium coverage with $25M+ limits, ideal for large AEC firms
Hiscox: Affordable standalone cyber starting at $67/mo for small firms

Why Engineering Firms Need Cyber Insurance

Engineering firms are increasingly targeted by cybercriminals. You store CAD files, BIM models, proprietary structural calculations, and client project data — all of which have significant value on the dark web. A 2025 industry report found that 43% of AEC firms experienced a cyber incident in the prior 12 months.

Beyond data theft, engineering firms face unique risks: compromised design files could lead to structural failures, and ransomware can halt active projects with tight deadlines. Unlike retail businesses, your cyber exposure often overlaps with professional liability, making bundled coverage essential.

What Cyber Insurance Covers for Engineering Firms

Coverage Type	What It Protects	Typical Limit
First-Party: Data Breach Response	Forensics, notification, credit monitoring	$500K–$2M
First-Party: Business Interruption	Lost income during system downtime	$250K–$1M
First-Party: Ransomware/Extortion	Ransom payments, negotiation costs	$500K–$1M
Third-Party: Liability	Client lawsuits from data exposure	$1M–$5M
Third-Party: Regulatory Defense	Fines from GDPR, state privacy laws	$250K–$1M
System Restoration	Rebuilding servers, recovering CAD files	$100K–$500K

Most engineering firms should carry at least $1M per occurrence / $2M aggregate in cyber coverage. Firms handling government contracts (CMMC compliance) or healthcare projects (HIPAA data) may need $5M+.

Common Cyber Threats for Engineering Firms

Ransomware attacks are the #1 threat. Attackers encrypt project files mid-construction and demand payment. Average ransom for mid-size firms: $150,000–$400,000.

Business email compromise (BEC) targets project managers and accounts payable. Attackers impersonate subcontractors or clients to redirect wire transfers. Engineering firms lost an average of $125,000 per BEC incident in 2025.

Phishing targeting CAD/BIM systems exploits the fact that engineers regularly share large files via email and cloud platforms. Compromised credentials give attackers access to entire project repositories.

Supply chain attacks through design software updates (AutoCAD, Revit plugins) can introduce malware across your entire firm.

Hartford is the best value for most engineering firms. It bundles cyber seamlessly with professional liability and general liability in a single BOP-style package. Chubb is ideal if your firm handles $10M+ projects or government contracts requiring premium coverage. Hiscox is the go-to for solo structural engineers and small consulting firms wanting affordable standalone cyber.

Bundling Cyber + E&O Coverage: Why Engineers Should Combine

Engineering firms face overlapping exposures. A compromised design file is both a cyber incident (data breach) and a professional liability claim (faulty deliverable). Buying separate policies can create coverage gaps — each insurer may deny the claim, pointing to the other policy.

Bundling saves 15–25% compared to standalone policies and eliminates gap risk. Hartford and Chubb both offer integrated cyber + professional liability packages specifically designed for AEC firms.

Key bundle considerations:

Ensure the cyber policy covers "wrongful act" triggers, not just data breaches
Check that E&O coverage extends to digitally delivered work products
Confirm business interruption covers project delay penalties
Verify the bundle includes regulatory defense for state engineer board complaints

How to Choose the Right Cyber Policy

Assess your data exposure: Count client records, project files, and employee PII. More data = higher limits needed.
Review contract requirements: Many clients and general contractors now require $1M+ cyber coverage in subcontracts.
Check your current E&O policy: Some professional liability policies include limited cyber coverage — but it is usually insufficient ($50K–$100K sub-limits).
Implement MFA and backups first: Carriers offer 10–20% discounts for firms with multi-factor authentication and tested backup systems.
Compare at least 3 carriers: Premiums vary by 30–50% for identical coverage. Use a comparison platform to see actual quotes.

Frequently Asked Questions

How much does cyber insurance cost for a small engineering firm?
Most firms with under 10 employees pay $800–$2,000/year for $1M in cyber coverage. Firms with clean claims history and strong security controls pay toward the lower end.

Does general liability cover cyber incidents?
No. General liability excludes electronic data and cyber events. You need a dedicated cyber policy or a professional liability policy with cyber endorsement.

Is cyber insurance required for government engineering contracts?
Increasingly, yes. Federal contracts under CMMC Level 2+ and many state DOT contracts now require proof of cyber coverage. Even when not mandated, it is a competitive differentiator in bids.

What is the most common cyber claim for engineering firms?
Ransomware (38%), followed by business email compromise (27%) and employee negligence/accidental data exposure (20%).

Can I get same-day coverage?
Yes. Hartford and Hiscox both offer same-day binding for firms under $10M revenue through digital platforms like Insura.
