Defense contractor insurance for startups — COI-ready before your contract deadline.
Defense technology startups face a unique government contractor insurance challenge: contracts require specific coverage before work begins, but traditional brokers take weeks. RiskCube compares 40+ top-rated carriers and gets you COI-ready in as little as 24–48 hours.
What is defense contractor insurance?
Defense contractor insurance is a package of policies — typically Tech E&O, Cyber, General Liability, D&O, and Workers' Comp — required by government contracts before work can begin. Coverage is structured around the contract's insurance exhibit and must satisfy DFARS, CMMC, and any prime contractor flow-down requirements.
Types of defense contractor insurance
Government and prime contracts specify the exact coverages you must carry before work begins. Most defense startups combine several of these into one coordinated program.
Technology E&O
The single most critical policy for defense-tech startups selling software, autonomy, or engineering — it covers a customer's financial losses from software failures, AI errors, and mission-planning mistakes. Primes set high limits for technology suppliers, commonly $3M and up to $10M, and require it before work begins.
Tech E&O InsuranceCyber Liability
Government contracts and sensitive data make defense-tech companies high-value targets. When a supplier touches a prime's network, primes commonly require dedicated cyber limits up to $10M. Cyber responds to ransomware, breaches, and regulatory investigations — including DFARS 252.204-7012 and CMMC inquiries — plus the 72-hour breach-reporting duty primes flow down.
Cyber Liability InsuranceGeneral Liability
Required by every major defense prime before work begins — limits typically run $1M per occurrence / $2M aggregate, and some prime contracts require higher. CGL covers bodily injury, property damage, premises liability, and products & completed-operations — the baseline for startups running test facilities, on government sites, or deploying hardware.
General Liability InsuranceWorkers' Compensation
The one coverage every defense prime and the federal government require without exception — statutory Workers' Comp for anyone with employees, almost always paired with Employer's Liability at a $1M limit. If your team works overseas on a U.S. government contract, the Defense Base Act (DBA) mandates separate federal coverage.
Workers' CompensationEmployer's Liability
Almost always required alongside Workers' Comp — every major defense prime mandates it, typically at a $1M limit. It covers employee-injury lawsuits that fall outside the workers' comp system, such as third-party-over actions when an injured worker sues a prime and the prime turns to you to indemnify the claim.
Employer's Liability InsuranceAutomobile Liability
Required by most defense primes — typically $1M–$2M combined single limit — covering owned, hired, and non-owned vehicles. It's triggered whenever your team drives onto a government installation or prime's facility, or operates any vehicle in performance of the contract, even a rental or an employee's car.
Automobile Liability InsuranceDirectors & Officers
Protects founders and board members from personal financial exposure, and is required by most venture investors as a closing condition. In defense, D&O also responds to governance challenges around export controls, security clearances, and regulatory-compliance decisions that carry personal liability.
D&O InsuranceProduct Liability
Critical for startups that manufacture or deploy physical hardware — drones, sensors, or autonomous vehicles. It covers bodily injury and property damage from a defective product. Primes fold products & completed-operations into the required CGL, and aviation or aircraft-products work can carry limits into the tens of millions.
Product Liability InsuranceKey Person Life
In deep-tech defense, the entire moat often lives in one or two irreplaceable specialists — the co-founder who built the core autonomy or guidance IP, or a cleared individual on a government contract. Key Person Life pays the company a tax-free benefit if that person dies, and investors and venture lenders frequently require it as a closing condition.

Top risks for defense startups
Ranked from RiskCube's risk analysis of 21 Y Combinator defense startups — by how severe each exposure is and how many companies it affects. These are the five that show up most, and where standard policies most often fail to respond.
1. Nation-state cyber breach & IP / CUI theft
For a defense startup, the crown jewels are code and design data — and adversary states and competitors know exactly where to find them. Across this cohort that means hypersonic and warhead design data, autonomy source and model weights, and sensor and targeting IP, much of it inside teams as small as two to nine people with early-stage security maturity. A single intrusion can exfiltrate the entire competitive moat and, where US contracts and controlled data are involved, trigger reporting duties, contract loss, and False Claims exposure — while off-the-shelf cyber policies exclude nation-state "acts of war" and sublimit trade-secret loss. RiskCube structures Cyber with regulatory-defense cover and negotiated state-actor carve-backs so the breach response and compliance fallout are financed rather than excluded.
2. Autonomy & AI decision failure
Autonomous perception and targeting software is now the beating heart of the modern defense platform — and its single largest uninsured exposure. Nearly every company in this cohort puts an algorithm in a decisive loop: interceptors and turrets that decide at machine speed whether to engage, one-way-attack drones that steer themselves onto targets, and perception systems that reconstruct or detect the picture that cues a response — so a single misclassification means a wrong engagement, a missed threat, or a collision. Resulting wrongful-harm and economic-loss claims run into the millions, yet standard Tech E&O excludes bodily injury and CGL excludes weapons, war and "algorithmic-decision" failures, leaving the loss unfunded. RiskCube places Technology E&O with affirmative AI/algorithm wording coordinated with a product-liability tower, so an autonomy failure is paid rather than denied.
3. ITAR / EAR export-control enforcement
Almost every defense-article maker is one licensing misstep away from a company-ending enforcement action. The exposure is structural and cross-jurisdictional: US-headquartered firms with overseas manufacturing, foreign-registered developers operating from the US, companies under a foreign export regime, and the hiring of foreign-national engineers all create unlicensed technical-data-disclosure risk. ITAR and EAR export-control violations carry criminal liability, seven-figure fines, and debarment that severs the government revenue the company is built on — and fines and penalties are uninsurable as a matter of public policy. RiskCube cannot insure the penalty, but places D&O with regulatory-investigation cover to fund defense costs and pairs clients with the compliance-program discipline — technology control plan, registration, foreign-person access controls — that keeps the exposure from ever maturing.
4. Test & operations physical loss
In early defense hardware, breaking prototypes is not an accident — it is the development method, and it is routinely uninsured. Companies in this cohort destroy rockets and airframes in static fires and live-flight tests, expect to lose fragile stratospheric aircraft on test flights, risk hand-built submersibles on sea trials, and have founders personally diving unproven life-support rigs. Standard property and inland-marine forms exclude items "undergoing testing" and experimental craft, so a one-off prototype with no market value — and any injured test crew — lands straight on a pre-revenue balance sheet. RiskCube arranges prototype / hull and marine cover with test-flight and R&D-in-progress extensions, plus Workers' Comp and Defense Base Act for test personnel, converting an expected write-off into a recoverable one.
5. Weapons / product liability — third-party harm
The moment a defense product operates in the field it can harm someone or something it was never meant to — and the standard policy is written precisely to avoid paying when it does. A strike drone with a guidance fault, a kinetic interceptor whose debris falls to the ground, an RF countermeasure dropping a drone onto bystanders, a defective aircraft part, or a breathing rig failing at depth all produce catastrophic third-party bodily-injury and property-damage claims. Off-the-shelf CGL and product forms carry blanket weapons, munitions, aircraft, war and "expected-or-intended-injury" exclusions, so a single serious loss can exceed the company's entire valuation with no cover behind it. RiskCube sources specialty munitions / defense Product Liability with weapons and war-risk carve-backs — and pursues SAFETY Act and government-contractor indemnification — so a collateral-damage claim is transferred rather than retained.
6. Key-person / founder concentration loss
In deep-tech defense, the entire moat often lives in the heads of one or two irreplaceable specialists. This cohort is full of two-founder autonomy teams, single founders who are also the test pilot or test diver, and companies whose guidance, propulsion, or low-light-AI expertise sits in a handful of people who cannot be rehired on a startup's runway. The death, disability, or departure of one founder halts delivery, breaches program milestones, and can collapse investor and customer confidence. RiskCube places Key Person Life and disability cover — with hazardous-activity riders where founders themselves run the trials — alongside D&O, giving the business the capital cushion to survive the loss and rebuild.
Who needs it?
Defense technology is no longer just primes and legacy contractors. A new generation of startups is building the software, sensors, and autonomous systems that define modern defense — and they all face the same insurance challenge: government contracts require coverage before work begins.
Defense software
You build mission-planning software, command-and-control systems, or logistics platforms for government clients. Enterprise and government buyers require Tech E&O and GL before contracts are executed.
Autonomous systems
You build drones, robotics, or autonomous vehicles for defense applications. Hardware + software creates compound liability exposure — both Tech E&O and GL are required, often alongside umbrella coverage.
Dual-use tech
Your technology serves both commercial and government markets — AI, cybersecurity, satellite, or communications. Cyber and Tech E&O cover both channels, and your program must satisfy both sets of contract requirements simultaneously.
What government contracts actually require
Defense contracts specify insurance requirements in detail. Before you apply for coverage, pull the insurance section from your contract and look for these four items — they determine exactly what you need to buy.
The insurance requirements for government contractors are written into the contract itself, and they apply whether you hold a prime award or a subcontract. A software contractor delivering code faces the same government contractor insurance rules as a hardware supplier: every policy, limit, and endorsement named in the contract must be bound and shown on a certificate of insurance before performance can begin. Because the federal fiscal year closes on September 30, award and start dates cluster into late summer, so a COI that arrives even a few days late can push your kickoff into the next quarter. Our subcontractor insurance requirements guide walks through every coverage, limit, and endorsement to confirm before you sign.
Required coverage types and limits
Most contracts specify minimum limits per occurrence and in aggregate for each coverage type. GL limits of $1M/$2M are standard. Tech E&O and Cyber commonly require $1M–$2M. Some prime contracts require $5M. Confirm exact limits before applying.
Additional insured requirements
Government contracts and prime contractors often require you to name them as additional insured on your GL and sometimes Cyber policy. The exact wording matters — a generic additional insured endorsement may not satisfy the contract language. RiskCube reviews your contract wording before binding.
Primary and non-contributory language
Many defense contracts require your policy to be primary and non-contributory — meaning your insurance pays before any other policy the government or prime contractor carries. This requires a specific endorsement. Without it, your COI may be rejected at contract execution.
Flow-down obligations from prime contracts
If you are a subcontractor, the prime contractor's insurance requirements flow down to you — often with the same limits and endorsements the prime carries. Read the subcontract insurance section carefully. RiskCube structures your program to satisfy both your direct contract and any inherited flow-down requirements.
Why vague descriptions cause delays or declines
Certain keywords — "military," "tactical," "drone," "autonomous" — cause underwriters to pause, request additional information, or decline to quote entirely. A submission that says "we build autonomous defense software" gets a slow response or none at all.
A submission that says "we build mission-planning software for SOCOM, deployed by human operators, no autonomous targeting, ITAR-registered, $2M revenue" gets quoted within 24–48 hours.
The difference isn't the risk — it's the clarity. Underwriters need to understand exactly what you do and what you don't do before they can price it. RiskCube prepares your submission with the operational specificity that gets responses.
What to prepare before applying
Have these ready before you start — submissions with specific operational detail get faster quotes and better pricing.
Full description of what you build and what you don't
Underwriters need to know: Is the software autonomous or human-supervised? Do you design the system or implement to customer specs? Do you manufacture hardware or write code only? The clearer the answer, the faster the quote.
Contract type and customer
Prime contract or subcontract? Direct with the DoD, or with a prime like Lockheed or Palantir? OTA, SBIR, or FAR-based? Customer type and contract structure determine which coverage forms apply and which carriers will quote.
ITAR, EAR, and CMMC status
Are you ITAR-registered? Do you handle Controlled Unclassified Information (CUI)? What CMMC level does your contract require? Carriers with defense-specific capacity underwrite these differently — disclosure upfront prevents coverage gaps at claim time.
Secure site and government facility access
Do employees work on-base, at secure facilities, or on government networks? On-site work adds GL exposure. Access to classified systems or government infrastructure affects cyber underwriting. List where your team actually operates.
Cyber controls summary
Cyber underwriters will ask about MFA, endpoint detection, backup procedures, and patch cadence — and for defense contractors, whether you store or transmit CUI, who has network access, and how subcontractors are controlled. A one-page cyber controls summary shortens the underwriting process significantly.
Insurance section of your contract
Pull the insurance exhibit or Section H of your contract before you apply. It specifies exact limits, required endorsements, additional insured wording, and certificate instructions. RiskCube builds your program to match it exactly — no guessing, no rejected COIs.

FAQs About Defense Technology Insurance
Government contractor insurance
What is government contractor insurance?
Government contractor insurance is the set of policies required before a company can perform work under a federal, state, or municipal contract. At minimum it includes Commercial General Liability, Tech E&O (for technology or software services), and Cyber Liability. Defense contracts additionally require Workers' Compensation, D&O, and sometimes Product Liability. The exact types and limits are specified in the contract's insurance section and must be evidenced by a Certificate of Insurance before work begins. For the full breakdown by coverage, limit, and endorsement, see our insurance requirements guide.
Coverage basics
What insurance do defense technology startups need?
Defense technology startups need six core policies: Tech E&O (software failures, sensor errors, mission-planning mistakes), Cyber Liability (data breaches, ransomware, DFARS/CMMC regulatory defense), Commercial General Liability (required in nearly every government contract before work begins), Workers' Compensation (required by state law for employees), D&O (protects founders and board members, required by most venture investors), and Product Liability (covers bodily injury and property damage from defective hardware — required for drone, sensor, and autonomous vehicle manufacturers). Government contracts specify exact limits and endorsements in their insurance exhibit — your COI must match that language before work begins. RiskCube compares 40+ carriers and issues COIs in 24–48 hours.
Do I need ITAR-specific insurance?
ITAR compliance is a legal obligation, not an insurance product. However, your Tech E&O and Cyber policies should be structured to respond to claims arising from regulated technology failures or data exposure involving controlled defense information. RiskCube reviews your specific contract and regulatory requirements and structures coverage accordingly. Read more on the ITAR (State Department / DDTC) and EAR (Commerce Department / BIS) regimes.
Cyber coverage
What cyber coverage do defense contractors need?
Defense contractors handling Controlled Unclassified Information (CUI), government networks, or critical infrastructure need cyber coverage that includes: breach response and forensics, regulatory defense (including DFARS and CMMC-related investigations), third-party liability for downstream impacts, and business interruption. RiskCube compares carriers that specifically underwrite government contractor cyber risk. Read more: DFARS 252.204-7012, NIST SP 800-171, and CMMC.
Cost & timing
How much does defense contractor insurance cost?
Cost depends on your contract type, revenue, employee count, data sensitivity, and the mix of coverages you need — a full stack typically combines Tech E&O, Cyber, GL, and D&O, with Workers' Comp calculated separately based on payroll. Because defense-tech risk profiles vary widely, RiskCube gives you real quotes from multiple carriers so you can compare actual pricing for your company rather than a one-size-fits-all estimate.
How fast can a defense startup get covered?
Most defense tech startups get quotes within 24–48 hours. Companies with government contracts or classified work may require additional underwriter review — typically 2–3 business days. RiskCube manages the process end-to-end so you can focus on the contract, not the paperwork.
