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 — covers customers' financial losses from software failures, AI errors, mission-planning mistakes, and professional-services errors. Contracts typically require it before work begins, making it the first deal-blocker to resolve.
Tech E&O InsuranceCyber Liability
Government contracts, sensitive data, and critical infrastructure make defense tech companies high-value targets. Cyber responds to ransomware, breaches, incident-response costs, regulatory investigations (including DFARS and CMMC-related inquiries), and third-party claims.
Cyber Liability InsuranceGeneral Liability
Required in nearly every government or enterprise contract before work can begin. CGL covers bodily injury, property damage, premises liability, and contractual liability — the baseline for startups operating test facilities, attending government sites, or deploying hardware.
General Liability InsuranceWorkers' Compensation
Required by state law for any company with employees, and often a contract requirement. If your team works overseas or on a U.S. military base under a government contract, the Defense Base Act (DBA) mandates separate federal coverage regardless of your state policy.
Workers' CompensationDirectors & 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.
D&O InsuranceProduct Liability
Critical for startups that manufacture or deploy physical hardware — drones, sensors, or autonomous vehicles. Covers bodily injury and property damage from a defective product, including design defects, manufacturing failures, and inadequate warnings. Increasingly required alongside GL for hardware work.

Top risks for defense startups
1. Government contract and regulatory risks
Most defense startups sell to the DoD, an intelligence agency, or a prime like Anduril, RTX, or Palantir — and every contract reviews your insurance against an exact exhibit. A missing additional-insured endorsement, a below-rating carrier, or limits that fall short of a prime's flow-down can stall execution or lose the award to a compliant competitor, even when you already "have insurance." Separate compliance obligations like ITAR registration sit outside insurance — but RiskCube structures contract-matched coverage through top-rated carriers and issues a COI in as little as 24–48 hours that satisfies the insurance exhibit on the first review.
2. Product and aviation liability for physical systems
If you build drones, autonomous vehicles, or hardware that flies, the FAA classifies your UAS as an "aircraft" — which triggers the aircraft exclusion buried in almost every standard general liability policy. That means a founder who bought "GL" often has no coverage for the one event most likely to bankrupt them: a crash that injures a bystander or destroys property during a demo or beyond-visual-line-of-sight flight. RiskCube closes this gap with dedicated aviation and UAS liability plus product liability, so a design defect or a lost link is actually covered.
3. Autonomy software failure and Tech E&O
For autonomy, counter-UAS, and defense-software companies, your product is a decision — and a wrong one is costly. When flawed mission-planning or a misclassification causes a customer's financial loss with no bodily injury or property damage, standard general liability never responds; that economic-loss exposure belongs to Technology E&O. RiskCube places Tech E&O with affirmative AI and algorithmic-error language for the financial-loss layer, and pairs it with product and aviation liability so the physical consequences of an autonomous system's error are covered too — a gap generalist brokers routinely miss.
4. Cyber and CUI / DFARS-CMMC exposure
Defense startups handle Controlled Unclassified Information, connect to government networks, and are high-value nation-state targets. A breach is not just forensics and downtime — it can trigger DFARS 252.204-7012 reporting, CMMC compliance scrutiny, potential False Claims Act exposure if self-attested controls were overstated, and loss of contract eligibility. Generic SaaS cyber policies underprice or exclude exactly this. RiskCube compares carriers that specifically underwrite government-contractor cyber risk, with regulatory-defense coverage for DFARS and CMMC investigations built in.
5. War, terrorism, and weapons exclusion gaps
Standard cyber, property, GL, and aviation forms carry war, hostile-action, terrorism, and weapons/munitions exclusions — and for defense-tech they can void coverage precisely when the loss is defense-related. A state-sponsored cyberattack can be denied under a war exclusion, as Mondelez discovered in a widely reported dispute with its insurer, and a claim touching a munitions or weapons component can fall through a weapons exclusion in a standard GL policy. RiskCube reviews and negotiates these exclusions, places weapons-adjacent exposure in specialty defense markets, and pursues affirmative cyber-war wording so a defense loss doesn't become an uninsured one.
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.
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.
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.
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.
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.
