Your business details

Why we ask these questions:

Cyber criminals target businesses differently based on industry, size, and data types. They don't just steal data - they use it for fraud: fake invoices, unauthorised payments, identity theft, and business email compromise. Our risk assessment uses real-world attack patterns and government data to show your specific exposure.

Type of business

Different businesses face different risk levels

Number of employees (including you)

Annual turnover

How We Calculate Your Cyber Risk

Average cyber attack cost (£990 base):

• Source: UK Cyber Security Breaches Survey 2025
• Adjusted by business type, security posture, and data sensitivity
• Healthcare businesses face 80% higher costs due to compliance requirements
• Poor security measures can increase costs by 100%

Financial fraud from data breaches (£5,900 base):

• Source: UK Cyber Security Breaches Survey 2025 (cyber-facilitated fraud)
• What this means: After stealing your data, criminals commit fraud against you or your customers
• Common examples: Unauthorized bank transfers, fake supplier invoices, stolen customer payment details, business email compromise requesting payments
• How we calculate YOUR risk: £5,900 × risk multipliers
• Risk multipliers include:
  - Business type: Healthcare (1.8×), Professional (1.3×), Retail (1.2×)
  - Data sensitivity: Financial data handling significantly increases fraud risk
  - Security posture: No security (2.0×), Basic antivirus (1.5×), Some tools (1.2×)
  - Revenue scale: Higher revenue businesses are targeted more (up to 5× for £500k+)
  - Employee count: 15% additional risk per employee beyond first
• Timeline: Fraud often happens weeks/months after the initial breach
• Real example calculation: A £100k healthcare practice with financial data and no security:
  Base fraud risk: £5,900
  × Healthcare multiplier: 1.8
  × Financial data risk: 1.6
  × No security: 2.0
  × Revenue factor: 1.0 (for £100k turnover)
  × Employee factor: 1.0 (single practitioner)
  = £5,900 × 5.76 = £33,984 annual fraud risk
  This means this practice faces nearly £34k in potential fraud losses per year

Business disruption & revenue Loss:

• Base: 1.9% of annual revenue (Howden Insurance Broker research 2024)
• Includes: Lost sales, productivity loss, customer churn, recovery costs
• Average UK business takes 38 days to identify and 43 days to recover
• Multiplied by risk factors: business type, data sensitivity, security posture

GDPR fines (1-4% of turnover):

• Legal maximum: 4% of annual turnover or €20 million
• Basic business data: 1% risk (lower ICO enforcement)
• Customer contact info: 1.5% risk
• Financial/payment data: 2.5% risk
• Personal/sensitive data: 3% risk
• Highly regulated data: 4% risk (maximum penalty likely)

Additional compliance requirements:

• Healthcare: CQC requirements, NHS Data Standards
• Professional Services: SRA, ICAEW, professional body standards
• Retail: PCI DSS for card payment processing
• Consultants/Trades/Creative: GDPR only

Risk multiplier factors:

• Business yype: Care providers (1.8x), Professional services (1.3x), Retail (1.2x)
• Current security: No measures (2.0x), Basic antivirus (1.5x), Some tools (1.2x)
• Revenue scale: Higher revenue = higher targeting (max 5x for £500k+ businesses)
• Employee count: More employees = larger attack surface (15% per additional employee)
• Data sensitivity: Multiple sensitive data types compound risk

Note: Even businesses with "some security tools" show elevated risk because modern threats require comprehensive, layered protection with 24/7 monitoring.

Why these calculations matter:

These aren't scare tactics - they're based on real government data and insurance industry research. Real example: A small accounting firm had their email compromised. Criminals sent fake invoices to clients requesting payment to a different bank account, stealing £12,000 before being discovered. The ICO has fined businesses millions for GDPR breaches, and cyber attacks cost UK businesses £27 billion annually.
