Key Takeaways
- Traditional VPNs grant network-wide access after a single login. This creates lateral movement risk that DORA and NIS2 auditors are increasingly flagging.
- Zero trust network access (ZTNA) verifies identity, device posture, and context for every session — not just at connection time.
- The enterprise standard in 2026 is hybrid: ZTNA for application access, VPN for network-level segmentation and egress control.
- Jurisdiction of the operating entity is the most overlooked sovereignty requirement. A Swiss or EU-incorporated provider is structurally different from a US or BVI provider, regardless of data center location.
- Audited no-logs policies are non-negotiable for DORA third-party risk documentation and GDPR Article 32 evidence.
- Proton VPN for Business offers the strongest jurisdictional position for EU-regulated organizations; NordLayer offers the strongest ZTNA feature maturity; ExpressVPN Team offers the simplest deployment.
Introduction: The Perimeter Is Dead — But the VPN Isn’t
For thirty years, enterprise remote access followed a simple model: authenticate once, cross the VPN “moat,” and access everything inside the network. The castle-and-moat architecture assumed that anyone who passed the perimeter could be trusted.
That assumption is now indefensible. The modern workforce operates from home networks, co-working spaces, client sites, and public Wi-Fi. Applications have migrated to SaaS and multi-cloud environments. Contractors, managed service providers, and third-party maintenance personnel require access to internal systems. And regulators — particularly under DORA and NIS2 — now require documented evidence that every access path is governed, logged, and reviewed.
The question is no longer whether you need encrypted remote access. It is what architecture satisfies both the threat model and the compliance framework — and how that architecture interacts with digital sovereignty requirements.
This guide defines the enterprise zero trust VPN architecture, compares leading providers against sovereignty criteria, and provides an implementation framework grounded in DORA, NIS2, and GDPR requirements.
ZTNA vs VPN: What’s the Difference?
Zero trust network access (ZTNA) and traditional VPNs are often presented as competing alternatives. They are not. They solve different problems, and most enterprise architectures need both.
| Criterion | Traditional VPN | Zero Trust Network Access (ZTNA) |
|---|---|---|
| Trust model | Trusted once connected | Never trust, always verify |
| Access scope | Network-wide after authentication | Per-application, per-session |
| Authentication | One-time at connection | Continuous (identity + device + context) |
| Lateral movement risk | High — broad network access | Minimal — no network-level exposure |
| Device posture enforcement | Typically limited or manual | Continuous and policy-based |
| User experience | Often requires manual connection | Fast, often transparent to user |
| Scalability | Requires VPN concentrator scaling | Cloud-native, elastic |

The critical insight for enterprise buyers: A VPN alone is no longer sufficient for application access. But ZTNA alone does not solve network segmentation, dedicated IP requirements, or egress control. The 2026 enterprise standard is hybrid.
Why DORA and NIS2 Auditors Are Flagging VPN-Only Architectures
The regulatory pressure on remote access governance has intensified dramatically. Under NIS2 Article 21, covered entities must implement “appropriate and proportionate technical, operational and organisational measures” including access control policies, multi-factor authentication, secured communications, and vulnerability handling[reference:0].
DORA goes further. Financial entities must maintain documented ICT risk management frameworks, ICT third-party risk governance, and — critically — documented exit strategies for every critical vendor relationship[reference:1].
What auditors are finding:
- Shared contractor accounts without individual attribution
- Inconsistent MFA enforcement across VPN groups
- Legacy VPN configurations with broad network access grants
- Logs too noisy to support forensic investigation
- No documented review process for remote access privileges
A modern remote access environment must account for VPN concentrators, ZTNA gateways, privileged access management jump hosts, bastion hosts, supplier maintenance tunnels, and emergency break-glass accounts — each of which is a potential regulatory evidence point[reference:2].
The enterprise response: Zero trust principles applied to remote access, with documented policy enforcement, continuous verification, and auditable logs.
The Four Requirements for Sovereign Remote Access
For organizations that must satisfy both security and digital sovereignty requirements, enterprise remote access must deliver four things:
1. Identity-First Access Control
Every session must be authenticated against the organization’s identity provider (Okta, Entra ID, Google Workspace, JumpCloud), with SSO and SCIM provisioning for lifecycle management. Shared accounts are no longer acceptable under NIS2 or DORA.
2. Device Posture Verification
Access should be granted only to devices that meet organizational security requirements — OS version, patch level, endpoint protection status, and encryption state. ZTNA enforces this continuously; traditional VPNs typically do not.
3. Jurisdictional Sovereignty
The country of incorporation of the provider matters more than the location of the data center. A US-incorporated provider is subject to the CLOUD Act regardless of where its servers sit. A Swiss-incorporated provider is not. This is the core of zero-knowledge architecture applied to network access.
4. Audited No-Logs Architecture
The provider must not store connection metadata that could be subpoenaed, breached, or misused. For DORA third-party risk documentation, an independent no-logs audit is the evidence that converts a policy claim into a verifiable fact.

Compliance Integration: DORA, NIS2, and GDPR
For regulated organizations, the remote access architecture must produce evidence for three distinct regulatory frameworks.
| Regulation | Requirement | How Zero Trust VPN Architecture Satisfies It |
|---|---|---|
| DORA (Reg. 2022/2554) | ICT third-party risk governance, documented exit strategies, concentration risk mitigation | Customer-held keys and data portability ensure functional exit capability. Audited no-logs reduces breach notification scope. |
| NIS2 (Dir. 2022/2555) | Access control policies, MFA, secured communications, supply-chain security | Identity-first access, continuous device posture verification, encrypted transit with audited no-logs. |
| GDPR (Art. 25, 32) | Data protection by design, security of processing, ability to demonstrate measures | Zero-knowledge architecture satisfies Article 25 by design. Audit reports provide Article 32 evidence. |
Critical DORA consideration: If your provider holds encryption keys or retains connection metadata, your documented exit strategy is functionally unenforceable. Zero-knowledge architecture with customer-held keys is the technical control that makes contractual exit rights real.
Implementation Framework
Phase 1: Audit Current Access Paths
Map every remote access route: corporate VPN concentrators, ZTNA gateways, PAM jump hosts, bastion hosts, supplier tunnels, break-glass accounts, SaaS admin portals, developer production access, BYOD exceptions. Each path is an evidence point[reference:7].
Phase 2: Define Access Policies
For each access path, document:
- Who is authorized (individual accounts, not shared)
- Authentication requirements (MFA mandatory for privileged access)
- Device posture requirements (OS version, patch level, endpoint protection)
- Session duration and re-verification frequency
- Logging and review cadence
Phase 3: Select Architecture
| If Your Priority Is… | Recommended Architecture |
|---|---|
| EU regulatory compliance, legal sovereignty | Proton VPN for Business + ZTNA broker for application access |
| Feature depth, ZTNA maturity | NordLayer (Core+ tiers) + identity provider integration |
| Deployment speed, performance | ExpressVPN for Teams + SCIM provisioning |
| Full SASE replacement | Check Point SASE / Zscaler Private Access |
Phase 4: Integrate with Identity Provider
Connect your chosen solution to Okta, Entra ID, Google Workspace, or JumpCloud via SAML SSO and SCIM provisioning. This ensures access rights are automatically revoked when employees leave or change roles.
Phase 5: Document and Test
Produce documented evidence for DORA/NIS2 auditors: architecture diagrams, policy documents, MFA enforcement reports, access review logs, and incident response procedures that reference remote access.
Frequently Asked Questions
Does zero trust replace VPN?
No. ZTNA addresses application access and eliminates lateral movement risk, but VPN still serves network-level segmentation, dedicated IP requirements, and egress control. Most enterprise architectures in 2026 use both.
What is the difference between ZTNA and a business VPN?
A business VPN grants network-wide access after a single authentication. ZTNA grants per-application access with continuous verification of identity, device posture, and context. ZTNA is more secure for application access; VPN remains relevant for network-level controls.
Which enterprise VPN has the strongest jurisdiction for EU compliance?
Proton VPN for Business (Switzerland). Swiss incorporation is outside US CLOUD Act reach and benefits from strong constitutional privacy protections. NordLayer (Panama) and ExpressVPN (BVI) are also outside CLOUD Act scope but have weaker statutory privacy frameworks than Switzerland.
Are no-logs audits required for DORA compliance?
DORA does not mandate no-logs audits specifically, but it requires documented ICT third-party risk management and evidence of appropriate security measures. An independent no-logs audit is the strongest evidence that a provider cannot disclose customer data it does not possess.
What is the minimum user count for enterprise VPN plans?
Proton VPN for Business starts at 2 users. NordLayer and ExpressVPN for Teams both start at 5 users.
Can I use a consumer VPN for enterprise remote access?
No. Consumer VPNs lack centralized administration, SSO/SCIM integration, audit logging, and compliance documentation required for DORA and NIS2. Enterprise plans from the same providers include these controls.
How does ZTNA support NIS2 Article 21 requirements?
NIS2 Article 21 requires access control policies, MFA, and secured communications. ZTNA enforces identity-first access, continuous device posture verification, and encrypted per-session connectivity — directly satisfying these requirements.
