Das Wichtigste in Kürze
- Nearly 1 in 5 tradespeople have been victims of cyberattacks (Signal Iduna)
- Premiums from 250 EUR/year for small businesses and solo operators
- Particularly at risk: Electrical, HVAC, automotive workshops
- Average cyber damage in Germany: 45,370 EUR (GDV 2024)
- IT security measures can reduce premiums by up to 10%
Germany has more than one million registered Handwerksbetriebe (ZDH, 2024). Most of them now handle invoices, banking, and customer records on a screen, and a Signal Iduna study put a number on what that means: roughly one in five tradespeople has already been hit by a cyberattack. The same survey found 74 percent still consider their own risk low — a gap that tends to close the day a ransomware note appears on the workshop PC. A cyber insurance policy does not stop the attack. What it does cover is the bill that follows: business interruption, IT forensics, ransom advice, and the cost of getting your data back.
Damage Examples from the Trades
Cyberattacks on tradespeople often follow a similar pattern: An employee opens a fake email, clicks on a malicious attachment, and within hours the business is at a standstill. The following three scenarios are typical for the trades.
Scenario 1: Electrical Business with Ransomware
An electrical trades business with 12 employees receives a fake invoice via email. After opening it, ransomware encrypts the accounting software and all customer data. Three weeks of business interruption, 15,000 EUR for IT forensics and data recovery, plus several thousand euros in lost revenue. The cyber insurance covers the costs for IT experts, compensates for lost income, and provides crisis consultants.
Scenario 2: HVAC Business with Online Banking Fraud
An HVAC business (sanitary-heating-air conditioning) receives a call, supposedly from their bank. The owner discloses access data and only notices two days later that 28,000 EUR has been transferred to an unknown account. The cyber insurance reimburses the damage and funds the switch to a secure banking procedure.
Scenario 3: Automotive Workshop with Data Breach
An automotive workshop with a connected diagnostic system is hacked. Customer data, including license plates, addresses, and bank details, ends up on the internet. Under GDPR, the business must report the data breach within 72 hours. Cyber insurance covers legal advice, notification of those affected, and potential compensation claims.
Special Risks for Tradespeople
According to Bitkom, 87 percent of all German businesses were affected by cyberattacks in 2024. Total damage amounted to 289.2 billion EUR. Tradespeople are vulnerable for several reasons.
Many businesses rely on simple IT infrastructure without professional management. The Signal Iduna study confirms: 75 percent of surveyed tradespeople believe their business is too small to interest criminals. In practice, however, automated attacks target businesses of all sizes. A business with an unsecured network is even an easier target for attackers than a corporation with its own IT department.
Typical Attack Vectors in the Trades
- Phishing (fake emails): 81 percent of surveyed tradespeople named emails with malicious attachments as the biggest threat (Signal Iduna)
- Weak passwords: 47 percent see insecure passwords as an entry point
- Ransomware: Encryption trojans bring the entire business to a halt. According to Coveware 2024, the average downtime after a ransomware attack is around 23 days
- Online banking fraud: Manipulation of transfers through compromised computers or stolen access data
- Connected machines and IoT: Smart home installations, connected heating systems, and CNC machines can become entry points with inadequate security

What Does Cyber Insurance Cost for Tradespeople?
The premium depends on business size, revenue, and degree of digitization. According to GDV, the average cyber damage in Germany is 45,370 EUR. The annual insurance premium is significantly lower.
| Business Type | Employees | Coverage (Maximum Reimbursement) | Premium From |
|---|---|---|---|
| Solo Tradesperson | 1 | 50,000 - 100,000 EUR | 250 EUR/Year |
| Small Business | 2-10 | 100,000 - 250,000 EUR | 400 EUR/Year |
| Medium Business | 10-50 | 250,000 - 500,000 EUR | 800 EUR/Year |
| Larger Business | 50+ | 500,000 - 1 Million EUR | 1,500 EUR/Year |
For comparison: A single ransomware attack can paralyze a trades business for several weeks. The costs for IT recovery, lost revenue, and potential data protection fines exceed the annual premium many times over. A detailed breakdown is available on our page Cyber Insurance Costs.
Cyber Risks by Trade
Not every tradesperson carries the same cyber risk. The deciding factor is the degree of digitization. The Bitkom study 2025 shows: 85 percent of tradespeople offer at least one digital service, while 96 percent cite IT security concerns as the biggest hurdle in digitization.
Electrical Trade
Smart home installations, building automation, connected systems. High digitization level with direct IoT access to customer properties.
Risk: High
HVAC (Sanitary-Heating-Air Conditioning)
Remote maintenance of heating systems, smart thermostats, connected heat pumps. Access to sensitive building data.
Risk: High
Automotive Workshops
Connected diagnostic devices, online spare parts ordering, digital customer data with license plates and bank details.
Risk: Medium to High
Metalworking / Carpentry
CNC machines, CAD software, digital order planning. Production downtime when systems are encrypted.
Risk: Medium
Construction Trades
Digital construction plans, order management software, mobile devices on construction sites.
Risk: Medium
Food Trades
Cash register systems, online orders, digital inventory management. Cash register system failure leads to immediate revenue loss.
Risk: Medium
Coverage Gaps and Exclusions
Before taking out cyber insurance, tradespeople should carefully examine the policy terms. The following limitations are common and can cause problems in case of damage.
- Obligations for IT security: Missing backups or outdated software can lead to benefit reductions
- Waiting periods after policy start: Some policies only cover damage after a waiting period of 7 to 30 days
- Sublimits: Individual services like online banking fraud may be capped at lower amounts
- Intentional misconduct: If employees knowingly violate security policies, coverage does not apply
- War and state attacks: Cyberattacks classified as warlike actions are typically excluded
- Pre-contractual damages: Attacks that occurred before insurance began but were only discovered later
NIS-2: What Does This Mean for Tradespeople?
The NIS-2 Directive (Network and Information Security Directive 2) has been in force since December 2025 and directly affects around 29,500 businesses in Germany according to BSI. Tradespeople are in most cases not subject to direct obligations.
Indirect impact is increasing, however. Larger clients and general contractors who are themselves subject to NIS-2 increasingly require proof of IT security from their subcontractors. As a tradesperson, having cyber insurance demonstrates compliance with these requirements and secures contracts. Read more in our guide to Cyber Risks for SME.
Improve IT Security, Reduce Premium
Insurers reward proven IT security measures with premium discounts. Hiscox grants up to 10 percent discount, HDI up to 7.5 percent. The following measures reduce both actual risk and insurance costs.
- Regular backups: Weekly on external media or cloud, stored separately from the network
- Software updates: Keep operating system, accounting software, and router up to date
- Employee training: Recognize phishing (fake emails), use secure passwords
- Multi-factor authentication: Additional security layer when logging in, especially for online banking and email
- Firewall and antivirus: Professional solution instead of consumer products, regularly updated
- Emergency plan: Documented procedure for emergencies, with contact details of IT service provider and insurer
More information on protection against the most common threat is available in our Ransomware Protection Guide.
What Tradespeople Should Consider When Comparing
When choosing cyber insurance, it's not just the premium and coverage amount that matter. The following six criteria help with the decision. Our comparison methodology is explained on How We Compare.
- Coverage amount appropriate for the business: Orient yourself by annual revenue and amount of stored customer data
- Business interruption protection: Check the maximum compensation period and daily rates
- Deductible (share in case of damage): Lower deductible means higher premium, but less out-of-pocket costs in case of damage
- IoT coverage: Crucial for businesses with connected machines and smart building technology
- 24/7 Crisis hotline: Immediate help in case of damage can significantly limit the damage
- Obligations: What IT security measures does the insurer require as a prerequisite for full coverage?
Cyber Insurance by Industry
Requirements for cyber insurance differ by industry. Compared to freelancers or larger SME, tradespeople have specific risks from connected machines and customer on-site access. The following comparison pages may also be relevant:
- Cyber Insurance for SME (general commercial businesses)
- Cyber Insurance for Freelancers (solo self-employed)
- Cyber Insurance for IT Service Providers (IT trade, system houses)
- Professional Liability (supplementary liability coverage)
- D&O topics (owner liability for larger businesses)
Für wen ist Tradespeople Cyber Insurance geeignet?
Geeignet für
- Tradespeople with digital order processing and online banking

Conclusion
Tradespeople are increasingly targets of cyberattacks. Ransomware can paralyze order planning, and a phishing attack is enough to expose customer data. Cyber insurance for tradespeople costs from around 300 EUR per year, depending on business size.
Important when choosing: Make sure business interruption damages are covered. Many tradespeople underestimate how quickly an IT outage can bring the entire daily operations to a standstill.
