Tech E&O insurance (short for Technology Errors and Omissions insurance) covers claims that your technology product or service failed to perform as promised and caused a client financial harm. If your software had a bug that corrupted client data, your managed services agreement promised 99.9% uptime and a misconfiguration on your end took a client offline for two days, or your cybersecurity product failed to detect a threat it was supposed to catch, those are tech E&O claims.
Tech E&O insurance is a professional liability policy. It covers the legal defense costs, settlements, and judgments that result when a client alleges your technology or services did not perform as contracted. It is distinct from cyber insurance, which covers security incidents. Both are necessary for technology companies and MSPs. Having one without the other leaves meaningful gaps.
This guide explains what tech E&O insurance covers, who needs it, how it works alongside cyber insurance, what it costs, and what underwriters evaluate when writing it.
What Tech E&O Insurance Covers
Tech E&O insurance is a liability policy. It responds to claims made by clients or third parties who allege that your technology product, software, platform, or professional services caused them financial harm.
Errors in your product or deliverable. A software bug that corrupts client data. A miscalculation in your SaaS platform that generates incorrect financial reports. A flaw in custom code you delivered that causes downstream system failures. If your technology did not perform as represented or contracted and a client suffered a financial loss as a result, that is a tech E&O claim.
Omissions and missed deliverables. A feature your team promised but did not deliver. A milestone you missed that caused a client to lose a contract. A service level agreement you failed to meet. Tech E&O coverage pays for the financial claims that follow when what you promised is not what you delivered.
Professional services failures. Tech E&O extends beyond software products to the professional services wrapped around them. If you are an MSP that recommended and implemented a solution that did not work, a consultant who designed an architecture that failed, or a cybersecurity firm whose monitoring missed a threat, the resulting client claims fall under tech E&O.
Legal defense costs. Even when a claim against you has no merit, defending it costs money. Tech E&O insurance covers legal defense costs regardless of whether the underlying claim is ultimately valid. A groundless lawsuit from a disgruntled client can cost $50,000 to $200,000 to defend before a single dollar in damages is ever established. Defense cost coverage is often where the most immediate value shows up.
Settlements and judgments. If a covered claim results in a settlement or a court judgment against you, tech E&O covers those amounts up to your policy limit.
What Tech E&O Insurance Does Not Cover
Tech E&O is a third-party liability policy. It covers claims made against you, not losses your business suffers directly.
Your own losses from a cyber incident. If your systems are breached, ransomware hits your infrastructure, or you suffer a business interruption from an attack on your own environment, that is cyber insurance territory. Tech E&O does not cover your first-party losses from a security incident.
Bodily injury or property damage. Tech E&O covers financial harm, not physical harm. If a failure in your technology causes physical injury or property damage, that may fall under general liability rather than E&O.
Intentional acts. Claims arising from fraud, intentional misrepresentation, or deliberate wrongdoing are excluded.
Prior known claims. Tech E&O is a claims-made policy. Coverage applies to claims made during the policy period arising from incidents that were not known before the policy began. If you knew about a problem before you bought the policy and a claim arose from it later, that claim is typically excluded.
Contractual liability beyond what the law would impose. If you accepted contractual obligations that go beyond standard professional liability, tech E&O may not cover the excess exposure you assumed by contract. Broad indemnification clauses and uncapped liability provisions in client contracts are worth reviewing with counsel before you sign them.
Tech E&O vs. Cyber Insurance: Understanding the Difference
This is where most technology companies and MSPs get confused. The two policies cover different categories of loss, and both are necessary.
A useful framing: cyber insurance covers what happens to you. Tech E&O covers what your client claims happened to them because of you.
Cyber insurance responds to security incidents: data breaches, ransomware attacks, business interruption from an attack, breach notification costs, and regulatory exposure. It covers both your direct costs and your liability to third parties whose data was affected.
Tech E&O insurance responds to professional failures: your product did not work, your service did not perform, your platform went down and cost a client money. No attacker needed. No data taken. Just a performance failure and a client with a claim.
Here is how the two policies respond to real scenarios:
Scenario 1: Your MSP suffers a breach. An attacker compromises your RMM platform and uses it to push ransomware to client environments. Your cyber insurance covers your forensic costs, breach notification, business interruption, and regulatory exposure. Your tech E&O covers the claims your clients bring against you for damage done to their environments through your systems.
Scenario 2: Your SaaS platform goes down. A misconfiguration causes your platform to be unavailable for 18 hours and a client misses a critical deadline as a result. They sue you for $400,000 in lost contract revenue. Cyber insurance does not respond because this was not a security incident. Tech E&O covers the claim.
Scenario 3: Your security monitoring missed a threat. A client suffers a ransomware attack and argues your MSSP failed to detect indicators your contract promised you would catch. The resulting lawsuit involves professional liability (tech E&O) and potentially cyber liability exposure depending on how the claim is structured.

Who Needs Tech E&O Insurance
Any company that sells, builds, maintains, or delivers technology products or services to clients carries tech E&O exposure. The risk is not limited to large software companies.
Managed service providers. MSPs take on explicit service obligations through their managed services agreements: uptime guarantees, security responsibilities, backup and recovery commitments, and help desk response times. When those commitments are not met and a client suffers a loss, the resulting claim is a tech E&O matter. For more on the full insurance picture for MSPs, see our post on cyber insurance for MSPs.
Managed security service providers. If your business model includes an explicit security mandate, whether that is SOC monitoring, vulnerability management, penetration testing, or incident response, your clients have a reasonable expectation that your services will prevent or detect threats. When a client suffers a breach that your services were supposed to prevent, tech E&O is what covers the resulting professional liability claim. See our post on cyber insurance for MSSPs for a full breakdown of how coverage works for managed security providers.
SaaS companies. If your platform processes client data, runs client operations, or integrates into client workflows, a failure has downstream financial consequences for your customers. SaaS companies face tech E&O exposure on every contract they sign. For more on the insurance needs of SaaS businesses, see our post on cyber insurance for SaaS companies.
IT consultants and systems integrators. Recommending the wrong solution, implementing a system that fails, or designing an architecture with a flaw that surfaces later all generate professional liability exposure. Consultants who do not carry tech E&O insurance are personally exposed if a client decides to pursue a claim.
Web developers and digital agencies. Agencies that build websites, applications, or digital products for clients carry E&O exposure if those products fail to perform. An e-commerce site that goes down, a client portal with a security flaw, or a custom application that does not meet specifications can all generate claims.
Fintech and healthtech companies. Technology companies operating in regulated industries carry elevated tech E&O exposure because the downstream consequences of a product failure are more severe. A fintech platform that miscalculates a transaction or goes down during a critical trading window, or a healthtech product that produces incorrect outputs, creates significant client harm and corresponding claim potential.
Technology staffing firms. If you place technology professionals with clients and warrant their qualifications or work product, you may carry tech E&O exposure for output delivered by your placements.
What Tech E&O Insurance Costs
Tech E&O insurance premiums vary based on revenue, the nature of your technology, your contract terms, and your claims history.
| Company Type | Annual Revenue | Typical Annual Premium |
|---|---|---|
| Small IT consultancy or MSP | Under $2M | $2,000 to $5,000 |
| Mid-size MSP or SaaS company | $2M to $10M | $5,000 to $15,000 |
| Growing tech company or MSSP | $10M to $50M | $15,000 to $40,000 |
| Established tech or SaaS platform | $50M+ | $40,000 to $150,000+ |
Many carriers now offer tech E&O and cyber insurance as a combined policy form. Combined coverage is often more cost-effective than purchasing the two separately and reduces the risk of gaps between the two policy forms.

What Underwriters Evaluate When Writing Tech E&O
Tech E&O underwriters are assessing your professional liability exposure: the complexity of your contracts, the nature of your service obligations, and the quality of your internal processes.
Contract terms and service level agreements. Underwriters review the obligations you have accepted in client contracts. Aggressive SLAs, broad indemnification clauses, and uncapped liability provisions all increase your exposure and your premium. If your contracts routinely accept obligations that exceed what your policy limits can support, that is worth addressing before renewal.
Revenue and client concentration. How much of your revenue comes from your single largest client? A client that accounts for 50% of revenue creates a concentration risk that underwriters price accordingly. A claim from that client has disproportionate severity potential.
Claims history. Prior tech E&O claims are the strongest predictor of future claims. A clean loss history is a meaningful underwriting positive. If you have had prior claims, carriers want to understand what remediation steps you took.
Quality control and testing processes. Underwriters look for evidence that you have internal processes for catching errors before they reach clients. Code review procedures, QA testing, documented change management, and structured implementation methodologies all reduce claim probability and your rate.
The nature of your technology. A company delivering low-stakes marketing tools carries a different E&O profile than one delivering financial software, healthcare technology, or critical infrastructure management tools. The more consequential a failure of your product would be for a client, the more scrutiny underwriters apply.
Security controls. Because tech E&O and cyber liability overlap significantly for technology companies, underwriters evaluating tech E&O often consider your security posture as well. MFA deployment, EDR coverage, incident response planning, and backup practices are relevant to both. For a full breakdown of the security controls that affect your insurability, see our cyber insurance requirements checklist.
How to Get Tech E&O Insurance
Tech E&O insurance is typically purchased alongside cyber insurance, either as a combined policy form from a single carrier or as two separate policies. The application asks about your revenue, the nature of your technology products and services, your client contract terms, your claims history, and your internal quality control processes.
Working with a broker who specializes in technology company insurance and has access to multiple carriers gives you the ability to compare tech E&O policy forms and pricing across the market. Coverage terms vary meaningfully between carriers, particularly around claims-made provisions, prior acts coverage, and how the policy coordinates with your cyber coverage.

Frequently Asked Questions
Is Technology E&O the same as professional liability insurance?
Technology E&O is a form of professional liability insurance specifically designed for technology companies. Standard professional liability (sometimes called E&O for non-tech industries) covers professional services failures in fields like law, accounting, and consulting. Technology E&O extends that concept to cover technology products, software, and tech-specific service obligations. They are structurally similar but the coverage forms are different and not interchangeable for tech businesses.
Do I need both Technology E&O and cyber insurance?
Yes, if you are a technology company or MSP. Cyber insurance covers your first-party losses from security incidents and your third-party liability for data breaches affecting your clients. Technology E&O covers claims from clients who allege your product or service failed to perform. The two policies cover different categories of loss. Relying on one without the other leaves gaps that can be expensive to discover at claim time.
What is a claims-made policy and why does it matter?
Technology E&O is typically written on a claims-made basis, meaning coverage applies to claims made during the policy period, not when the incident occurred. This is different from occurrence-based policies. The practical implication: if you cancel your Technology E&O policy and a client later files a claim for work you did during the covered period, you may not have coverage unless you purchased an extended reporting period (tail coverage). When changing carriers, make sure you understand how prior acts are handled.
Does Technology E&O cover a data breach at my company?
Not directly. A breach of your own systems is a first-party loss covered under cyber insurance. However, if that breach exposed client data and your clients bring claims against you for failing to protect their information, those third-party claims may trigger both your cyber liability coverage and your Technology E&O coverage depending on how the claims are structured. This is exactly why having both policies, ideally from a single carrier who can coordinate the response, matters.
What limits should a small MSP carry?
Most small MSPs start with $1M per occurrence / $1M aggregate. Whether that is adequate depends on the size of your client contracts and the obligations you have accepted in your MSAs. If your largest client contract involves a multi-million dollar environment and your MSA accepts broad indemnification language, $1M may not be sufficient. A review of your largest client contracts is the right starting point for determining appropriate limits.
What is tail coverage and do I need it?
Tail coverage, formally called an extended reporting period endorsement, allows you to report claims after your policy has expired for incidents that occurred while the policy was in force. It is relevant whenever you are canceling or non-renewing a claims-made policy, changing carriers, or winding down a business. The cost varies but is typically 100% to 200% of your annual premium for a three-year tail. If you are changing tech E&O carriers, confirm whether your new carrier provides prior acts coverage before letting your existing policy lapse.
Does tech E&O cover AI-related failures?
Increasingly, yes, though policy language varies. As more technology companies build AI-driven products and services into their platforms, underwriters are paying closer attention to how AI errors, hallucinations, or unexpected outputs might generate professional liability claims. Some carriers have begun adding AI-specific exclusions or sublimits, while others are broadening coverage to address the exposure. If your product incorporates AI components, reviewing how your tech E&O policy defines a covered error or omission is worthwhile.
