Remote work is not the problem. Uncontrolled remote access is. If your team handles sensitive diligence documents, client data, or internal systems, choosing a business VPN is a security decision with operational consequences.
This post explains what makes a VPN “business-grade,” how to evaluate common options and architectures, and when you should consider ZTNA instead. We will cover selection criteria, a short evaluation checklist, and deployment tips that work for teams across the United Kingdom, the United States, and Canada.
Business VPN requirements in 2026
A business VPN should do more than encrypt traffic. It should support governance, visibility, and integration with identity. Look for:
- Central management: user provisioning, revocation, and policy control.
- SSO and MFA: integrate with Okta or Microsoft Entra ID.
- Device posture support: restrict access to managed, compliant devices.
- Modern protocols: WireGuard support is often favored for performance and simplicity.
- Logging: authentication logs and session telemetry for investigations.
- Split tunneling controls: configurable to reduce risk without breaking performance.
VPN vs ZTNA: which should you choose?
Ask a simple question: do users need network access, or do they need application access? VPNs often grant network-level access. ZTNA limits access to specific apps and is aligned with zero trust networking.
Many organizations use a hybrid model:
- ZTNA for internal web apps, admin portals, and SaaS management.
- VPN for legacy systems, certain developer workflows, or specific compliance constraints.
Business VPN options to consider (by architecture)
Rather than naming a single “best” VPN for everyone, it is more useful to categorize by what you are optimizing for.
1) Enterprise firewall-based VPN
Common in environments using vendors like Cisco, Fortinet, or Palo Alto Networks. Strengths include mature policy control and tight integration with network security. Trade-off: can become complex and may encourage broad network access if not carefully segmented.
2) Cloud-managed VPN services
These emphasize simpler deployments, centralized control, and rapid scaling. They can be a fit for distributed teams with many small sites.
3) Self-hosted VPN with strong ops discipline
Options like WireGuard or OpenVPN can work well if you have operational maturity: key management, monitoring, and a patching process. Trade-off: you own reliability and security hardening.
Security considerations that affect due diligence and VDR work
If your VPN is used to reach systems that store sensitive documents, a compromise can have real financial impact. The IBM Cost of a Data Breach Report 2024 shows breach costs remain high, which increases the value of stronger access controls and faster incident containment.
For deal workflows, consider isolating VDR administration to hardened devices and networks, even if reviewers connect more broadly.
Evaluation checklist (use this in procurement)
- Does it integrate with SSO and support mandatory MFA?
- Can we restrict access based on device compliance?
- Do we get detailed authentication and session logs?
- Can we segment access so users only reach required subnets or apps?
- How fast can we revoke access for a departing advisor?
- What is the operational burden (updates, certificates, keys)?
Deployment tips that reduce support load
- Start with least privilege routes: avoid “any-to-any” access.
- Use role-based groups: finance, legal, IT admins, and third parties should not share policies.
- Log to a central system: forward logs to your SIEM for correlation.
- Run access reviews: especially for external contractors and temporary users.
FAQ
Is a VPN enough to protect remote work?
No. A VPN encrypts traffic, but it does not prevent account takeover. You still need MFA, endpoint security, and least privilege access.
Should we force all traffic through the VPN?
It depends. Full tunneling can improve control, but may introduce performance issues. If you allow split tunneling, compensate with stronger endpoint controls and monitoring.
How does VPN choice affect ransomware risk?
Broad VPN access can increase lateral movement opportunities. Combine VPN with segmentation and incident playbooks. For response steps, see ransomware response.
