4. Segment Your Network

  • Create network zones for HR, finance, guest Wi-Fi, etc.

  • Use firewalls and VLANs to restrict lateral movement

✅ Tools:

5. Limit Application Access

  • Implement Zero Trust Network Access (ZTNA) instead of VPN

  • Restrict access to apps based on user/device identity

✅ Tools:

6. Encrypt and Monitor Data

  • Enable TLS 1.3 across your website and services

  • Encrypt backups and cloud storage

  • Use Data Loss Prevention (DLP) policies

✅ Tools:

7. Implement Continuous Monitoring

  • Use a lightweight SIEM to log and analyze activity

  • Set alerts for unusual logins, access patterns

✅ Tools:

 Example: Zero Trust in a Small E-Commerce Business

Component Traditional Approach Zero Trust Upgrade
User Logins Username/password only MFA + SSO with Okta or Google Workspace
Remote Work Access VPN access to all servers ZTNA with Cloudflare Access
Internal Network Flat LAN VLAN segmentation (POS, staff, guest Wi-Fi separated)
Endpoint Protection Basic antivirus EDR + device health checks (SentinelOne)
File Access Open shared drives Role-based access + cloud DLP (Microsoft Purview)

 Best Practices for Zero Trust Success in SMBs

  1. Start Small, Scale Smart

    • Begin with MFA, then expand to ZTNA and segmentation

  2. Prioritize High-Value Targets

    • Protect customer data and financial systems first

  3. Leverage Managed Security Providers

    • Use MSSPs if you lack in-house security expertise

  4. Train Employees

    • Run phishing simulations and cybersecurity awareness campaigns

  5. Automate Where Possible

    • Use automated alerts, access reviews, and patch management
