Data Security and Compliance for Field Service Companies

Data Security and Compliance for Field Service Companies

Your technician's phone gets stolen from their truck.

On that phone: Customer names, addresses, phone numbers, credit card information, access codes, and service history for 500+ customers.

Within 72 hours, you must:

• Notify every affected customer
• Report the breach to authorities
• Face potential fines up to $50,000
• Deal with reputation damage
• Potentially face lawsuits

This is preventable.

Why Field Service Businesses Are Targets

You Have Valuable Data

Customer information you collect:

• Names and contact information
• Home addresses
• Phone numbers
• Email addresses
• Payment card information
• Bank account details (for ACH)
• Access codes and security systems
• Property details and layouts
• Service history and equipment data

Why criminals want it:

• Identity theft
• Credit card fraud
• Home burglary (they know when you're not home)
• Resell on dark web

Value: Full identity record sells for $50-200 on dark web

Mobile Workforce = Bigger Attack Surface

Security challenges unique to field service:

• Technicians work from phones/tablets
• Devices leave secure office
• Public WiFi usage
• Lost or stolen devices
• Personal and work data mixed
• Multiple access points
• Less IT oversight

Result: 60% of small businesses suffering data breaches go out of business within 6 months.

Legal Requirements (You Can't Ignore These)

PCI DSS Compliance (Payment Card Industry)

Applies if you: Accept credit or debit cards

Key requirements:

Essential Security Practices

1. Mobile Device Security

Enforce device security policies:

• ✅ Require strong passwords/PIN (6+ characters, not "1234")
• ✅ Enable biometric authentication (fingerprint, face ID)
• ✅ Auto-lock after 2-5 minutes of inactivity
• ✅ Encrypt device storage (on by default for modern devices)
• ✅ Enable remote wipe capability
• ✅ Require OS and app updates
• ✅ Install mobile device management (MDM) software

Device options:

Option 1: Company-owned devices

• Pros: Full control, better security, consistent hardware
• Cons: Higher upfront cost ($500-1,000 per device)

Option 2: BYOD (Bring Your Own Device)

• Pros: Lower cost, employees prefer familiar devices
• Cons: Less control, compliance challenges, security risks

Recommendation: Company-owned for field technicians

What to do if device is lost/stolen:

1. Remote wipe immediately (within hours)
2. Change passwords for affected accounts
3. Notify affected customers (if data was on device)
4. Document incident
5. Report to authorities if required

2. Access Control

Principle of least privilege: Give access only to what's needed

Role-based access:

Technicians:
- View assigned jobs ✓
- Update job status ✓
- Process payments ✓
- View customer data (limited) ✓
- Edit customer data ✗
- View other techs' schedules ✗
- Access financial reports ✗

Office Staff:
- View all jobs ✓
- Schedule jobs ✓
- View/edit customer data ✓
- Run reports ✓
- Process refunds ✓
- Change system settings ✗

Managers:
- Full access to operations ✓
- View financial reports ✓
- User management ✓
- Change critical settings ✗

Administrators:
- Full system access ✓

Authentication best practices:

• Require strong passwords (12+ characters, mix of types)
• Enable two-factor authentication (2FA) for all users
• Force password changes every 90 days
• Prevent password reuse (last 5 passwords)
• Lock account after 5 failed login attempts
• Auto-logout after 30 minutes of inactivity

3. Data Encryption

Encrypt data everywhere:

In transit (moving between devices and servers):

• Use HTTPS/TLS for all web traffic
• Use VPN for sensitive connections
• Avoid public WiFi for sensitive data
• Use encrypted messaging for communication

At rest (stored on servers or devices):

• Encrypt databases
• Encrypt file storage
• Encrypt backups
• Use encrypted email for sensitive communications

Payment data:

• Use tokenization (store token, not card number)
• End-to-end encryption for card readers
• Never email credit card numbers
• Use secure payment gateway

4. Network Security

Protect your office network:

• Business-grade firewall ($300-1,000)
• Separate WiFi for guests (no access to business network)
• Virtual Private Network (VPN) for remote access
• Intrusion detection system
• Regular security updates

WiFi security:

• WPA3 encryption (or WPA2 minimum)
• Strong password (not "password123")
• Hide SSID broadcast
• MAC address filtering
• Separate guest network

Cloud security:

• Use reputable cloud providers (AWS, Azure, Google Cloud)
• Enable encryption at rest and in transit
• Configure proper access controls
• Regular security audits
• Backup to multiple locations

5. Regular Backups

3-2-1 backup rule:
