A VPN gives someone a tunnel into your network. Zero trust gives them access only to the app or data they actually need. For small businesses, that difference is the line between simple remote access and real access control.
#VPN vs zero trust: what is the difference?
A traditional VPN was built to extend the office network to remote users. Once connected, that user often lands inside the internal network and can reach far more than they need.
Zero trust works differently. NIST defines it as an approach that protects access to enterprise data regardless of where the request comes from, and its guidance says remote users should not be forced to use a VPN link back to the enterprise just to reach hosted services. That is a clear shift from network trust to application trust.
In plain terms:
- VPN = broad network access
- Zero trust = narrow, verified access
That matters because attackers rarely stop at the first account they compromise. If they get into a VPN-connected laptop, they may be able to move sideways across shared drives, servers, and admin tools. Zero trust is built to reduce that blast radius.
#When a VPN is still the right choice
A VPN is not obsolete. It is still a practical option when you need simple encrypted remote access to a small set of internal systems, especially in older environments that were never designed for cloud-first security.
For many SMEs, a VPN makes sense if:
- You have a small team and one or two internal systems
- Your remote access needs are basic
- You are running legacy line-of-business software
- You need a fast setup with low admin overhead
The downside is scope. A VPN usually trusts the device after login, which means one stolen password can become a much bigger problem than it should be. ENISA’s 2025 technical guidance explicitly recommends MFA on internet-facing systems including VPNs, which shows that VPNs need extra controls to stay acceptable.
#When zero trust is the better fit
Zero trust is the better model when your team works across Microsoft 365, cloud apps, remote endpoints, contractors, and personal devices. NIST’s architecture is designed for access to resources across on-premises and cloud environments, and ENISA also points organisations toward zero-trust network access where appropriate.
That makes zero trust a stronger fit if you want:
- App-specific access instead of full network access
- Stronger protection for remote staff and third parties
- Better control over unmanaged devices
- Less risk of lateral movement after a compromise
- Cleaner alignment with modern identity-based security
A useful way to think about it: VPNs move the perimeter to the user. Zero trust removes the idea that the user’s location is enough to trust them.
The real security difference is not encryption. Both models can encrypt traffic. The difference is whether a compromised login opens a whole internal network or just one approved application.
#VPN vs zero trust: side-by-side comparison
| Factor | VPN | Zero trust |
|---|---|---|
| Access model | Broad network access | Specific app or resource access |
| Best for | Legacy systems, simple remote access | Cloud apps, remote teams, contractors |
| Security scope | Protects the tunnel | Verifies user, device, and context continuously |
| Lateral movement risk | Higher | Lower |
| Setup complexity | Usually simpler | More planning and policy work |
| Ongoing admin | Lower at first | Higher at first, cleaner long term |
| User experience | One login, then broad access | More prompts, but less unnecessary access |
| Fit for growth | Limited | Better for scaling teams and hybrid work |
#What Malta businesses should choose
For many Malta SMEs, the answer is not “VPN or zero trust” in the abstract. It is “what are we trying to protect, and how much old infrastructure are we still carrying?”
If you are a small firm with a couple of remote users and a legacy server in the office, a VPN can still be the right first step. If your staff work mainly in Microsoft 365, file storage, cloud accounting, and line-of-business SaaS, zero trust usually makes more sense because the real environment is no longer the office network.
The other factor is risk. Malta businesses are subject to the same practical problems as everyone else: phishing, stolen credentials, unmanaged devices, and remote access sprawl. Once people start working from home, coffee shops, client sites, and mobile hotspots, the old “inside the network = safe” assumption stops holding up.
If you are already thinking about identity controls, MFA, and device compliance, you are halfway to zero trust. If you are still relying on a VPN as your main control, you should treat it as a transport tool, not a security strategy.
#How to decide without overcomplicating it
Use this checklist to choose the right path:
-
List every remote access use case Include staff, contractors, suppliers, and admins. If most of them only need one or two cloud apps, zero trust is the better direction.
-
Identify what is still on-premises If key systems live on an internal server and cannot be replaced soon, a VPN may still be needed during the transition.
-
Turn on MFA everywhere first ENISA explicitly calls out MFA for VPNs and other internet-facing systems. If you do nothing else, start here.
-
Check device control If you cannot trust every laptop or phone, zero trust gives you more room to enforce policy by device health and identity.
-
Separate admin access from normal user access Admin tools should never sit behind the same broad access path as everyday staff.
-
Plan for gradual migration Many businesses run VPN and zero trust together for a while. That is normal and often the safest route.
If you are already trying to tighten remote access, this is closely related to How to Set Up a Reliable Hybrid Office IT Environment and NIS2 compliance checklist for Malta SMEs in 2026.
The short version: use a VPN if you need quick encrypted access to legacy systems. Use zero trust if you want modern access control that matches cloud work, remote staff, and tighter security expectations.
