Business VPN vs ZTNA: Do SMBs Really Need Zero Trust in 2026?
Zero Trust Network Access (ZTNA) is the architecture that's replaced VPNs in enterprise security. But does it make sense for a 10-person SMB? Here's an honest breakdown of when a traditional VPN is still fine, and when you've genuinely outgrown it.
VPN vs ZTNA: what's actually different
A traditional VPN creates an encrypted tunnel between a remote device and your network. Once connected, the device has broad access to network resources — file shares, internal tools, servers. It's like giving someone a key to the building and trusting them to only go where they're supposed to.
ZTNA flips that model. Instead of broad network access, ZTNA grants access to specific applications or resources on a per-session, per-user, per-device basis. Access is verified continuously, not just at login. If a device's security posture degrades mid-session (e.g. antivirus disabled), access can be revoked automatically.
Traditional VPN
- Simple to set up and understand
- Works with all applications
- Cheaper upfront
- Broad network access once connected
- Lateral movement risk if device compromised
- Single point of failure
ZTNA (e.g. NordLayer)
- Granular per-app access control
- Continuous device trust verification
- Limits blast radius of a breach
- More complex initial setup
- Higher monthly cost
- May require app-level configuration
When a VPN is still enough
✓ A traditional VPN is probably fine if:
- Your team is fully on-site or rarely remote
- You have fewer than 10 people accessing company resources remotely
- You use mostly cloud-based tools (Google Workspace, Microsoft 365) rather than on-premises servers
- Your compliance requirements don't specify Zero Trust architecture
- You don't handle particularly sensitive data (financial records, health data, personal data at scale)
For very small teams using cloud-first tools, a consumer-grade business VPN may be sufficient — or even unnecessary if everything is already cloud-hosted and secured with MFA.
When you need ZTNA
You've probably outgrown a VPN if:
- You have remote or hybrid employees accessing sensitive internal systems regularly
- You use contractors or third parties who need limited access to your systems
- You have compliance requirements (ISO 27001, SOC 2, GDPR) that audit access controls
- You've had a security incident where lateral movement was a factor
- Your IT team can't easily audit who accessed what, when
The inflection point for most SMBs is when remote access becomes routine rather than occasional, or when you start using contractors who should only see specific parts of your systems — not everything a regular employee can see.
NordLayer: ZTNA built for SMBs
Most ZTNA solutions are built for enterprise IT teams with dedicated security staff. NordLayer is the exception — it's built on NordVPN's infrastructure but designed specifically for small and medium businesses that want ZTNA-level security without a full-time IT department to manage it.
Key features that matter for SMBs:
- Application-level access control — grant a contractor access to your project management tool without giving them access to file shares or internal databases
- Device posture checking — devices with outdated OS or disabled security software can be blocked automatically
- Centralised access management — add, remove, and modify access for team members or contractors without touching individual device configurations
- Audit logs — see who accessed what and when, useful for compliance and incident response

Cost comparison
For a 10-person team accessing remote resources:
- Traditional business VPN (e.g. OpenVPN on a cloud server): ~€20–50/month for the server, plus management time
- NordLayer Lite: from $8/user/month → ~$960/year for 10 users
- NordLayer Core: from $11/user/month → ~$1,320/year for 10 users (adds device posture checking)
The cost difference is real but the security gap is significant. For teams where remote access security matters, NordLayer's Core plan delivers enterprise-grade ZTNA at an SMB price.
Verdict
Stick with a VPN if your team is mostly on-site, you use cloud-first tools, and remote access is occasional.
Move to NordLayer if remote or hybrid work is routine, you use contractors, you have compliance requirements, or you want granular control over who accesses what.
