The Death of the VPN
Why 65% of Organizations Are Migrating to Zero Trust Secure Remote Network Access in 2026
For more than two decades, Virtual Private Networks (VPNs) were the backbone of remote access. They extended corporate networks beyond physical boundaries and enabled secure connectivity for distributed teams.
But in 2026, that model is collapsing.
According to industry analysts, 65% of organizations are actively migrating to Zero Trust Network Architecture (ZTNA). The reason is simple: VPNs were built for a world that no longer exists.
Hybrid work, cloud-native applications, and increasingly sophisticated cyber threats have exposed fundamental flaws in the VPN model. What once secured access is now one of the largest attack surfaces in modern enterprise environments.
This shift is not incremental. It is structural. And it is redefining how organizations approach secure remote access into their most critical assets.
Why VPNs Are Dying in 2026
Too Much Trust, Not Enough Control
Policies are tied to:
VPNs were designed around a perimeter-based security model. Once a user connects, they are effectively placed inside the network.
That is the core problem.
A compromised credential or device doesn’t just grant access to a single application. It often provides broad network-level visibility, enabling attackers to move laterally across systems.
This “all-or-nothing” access model creates a massive blast radius. One breach can quickly escalate into a full network compromise.
In contrast, modern architectures require least-privilege, identity-based access, where users only connect to what they explicitly need.
VPNs Enable Lateral Movement
One of the most dangerous characteristics of VPNs is their inability to enforce granular segmentation.
Once inside, attackers can:
- Scan the network
- Identify high-value assets
- Pivot across systems (East/West movement)
- Modern cybersecurity frameworks, including Zero Trust Network Architecture, specifically aim to eliminate lateral movement.
Solutions like CSOI enforce microsegmentation, ensuring that devices and users are isolated by default and must be explicitly authorized to communicate.
Forced Obsolescence by Vendors
Many major firewall and networking vendors are actively deprecating SSL VPN features in favor of Zero Trust Network Architecture models.
This is not accidental.
It reflects a broader industry acknowledgment that perimeter-based access is no longer viable. Organizations are being pushed toward:
- ZTNA
- Identity-defined networking
- Software-defined perimeters
- deny-by-default
The shift is happening whether organizations are ready or not.
VPN Appliances Are Prime Attack Targets
VPN infrastructure typically sits exposed on the public internet. This makes it highly visible and highly attractive to attackers.
Over the past several years, ransomware campaigns and nation-state actors have increasingly targeted VPN appliances due to:
- Known vulnerabilities in firmware
- Slow patching cycles
- Misconfigurations
- Once exploited, these systems provide a direct gateway into internal networks.
This is especially dangerous for critical infrastructure sectors. Many organizations still rely on legacy VPN deployments that were never designed to withstand modern attack techniques.
VPNs Were Never Built for the Cloud
VPNs were designed for on-premises environments. Today’s infrastructure is:
- Hybrid (on-prem + cloud)
- Multi-cloud
- Highly distributed
- VPNs struggle in this environment because they:
- Add latency through centralized gateways
- Create bottlenecks
- Lack visibility into application-level access
- As a result, many organizations now view VPNs as operational overhead, or as some have described them, “dead weight” in modern architectures.
The Rise of ZTNA: A Better Model for Modern Security
Zero Trust Network Architecture (ZTNA) represents a fundamental shift in how access is granted and secured.
Instead of trusting users once they are “inside,” ZTNA assumes:
- No user, device, or system should be trusted by default.
Every connection is verified, authorized, and continuously monitored.
1. Application-Level Security
ZTNA eliminates network-wide access.
Instead, users connect only to specific applications or resources they are authorized to use.
This dramatically reduces risk by:
- Limiting exposure
- Preventing network discovery
- Blocking unauthorized lateral movement
This aligns with CSOI’s approach of device-level and identity-based access controls, rather than network-layer access.
2. Identity-Based Access Control
ZTNA relies on strong identity verification, including:
- User identity
- Device posture
- CSOI enhances this further by using cryptographic identities instead of traditional IP-based access, making it significantly harder for attackers to impersonate systems.
3. Reduced Attack Surface
Unlike VPNs, ZTNA does not expose internal infrastructure to the public internet.
This is achieved through:
- Network cloaking
- Software-defined perimeters
- Invisible infrastructure endpoints
With CSOI’s architecture, devices and resources are hidden by default which drastically reduces the attack surface and prevents unauthorized discovery.
4. Continuous Authentication
ZTNA enforces continuous verification rather than a one-time login.
This means:
- Sessions can be revoked instantly
- Risk signals can trigger re-authentication
- Compromised accounts are contained faster
This is critical in environments where threats evolve in real time.
5. Improved User Experience
ZTNA is not just more secure. It is also more efficient.
Users benefit from:
- Direct application access
- Reduced latency
- Seamless connectivity across environments
This is especially valuable for distributed teams and hybrid workforces.
Real-World Impact Across Key Industries
Energy and Utility Organizations
Energy infrastructure is a high-value target for cyberattacks. Systems like SCADA were originally designed for isolated environments but are now connected to the internet.
This creates significant risk.
VPN-based access to these systems can expose entire networks if compromised.
CSOI addresses this by:
- Enforcing zero-trust access to SCADA systems
- Segmenting critical infrastructure
- Preventing unauthorized device communication
- In energy environments, this means:
- Reduced risk of operational disruption
- Protection against ransomware targeting control systems
- Secure remote access for operators and vendors
Government and Public Sector
Government agencies face increasing pressure to adopt Zero Trust, driven by mandates like Executive Order 14028.
These mandates require:
- Strong identity verification
- Secure cloud adoption
- Protection against supply chain attacks
CSOI aligns directly with these mandates by enabling:
- Identity-based access controls
- Encryption and segmentation across environments
- Secure communication channels that meet federal standards
This ensures agencies can modernize without compromising national security.
Manufacturing and Industrial Environments
Manufacturing environments are particularly vulnerable due to:
- Legacy systems (often unpatchable)
- OT/ICS devices without built-in security
- Third-party vendor access
VPNs introduce significant risk in these environments by granting broad access to internal networks.
CSOI mitigates this through:
- Microsegmentation of production systems
- Identity-based access for vendors and technicians
- Isolation of critical assets like robotics and control systems
This prevents attackers from moving laterally across the plant floor and disrupting operations.
Practical Migration Strategy: Moving from VPN to ZTNA
Transitioning away from VPNs does not require a disruptive rip-and-replace approach. In fact, the most effective strategies are incremental.
Step 1: Inventory and Classify Access
Start by identifying:
- Users
- Devices
- Applications
- Access points
Map who needs access to what, and why through which gate.
Step 2: Define Least-Privilege Policies
Replace broad network access with:
- Application-specific permissions
- Role-based access controls
- Device-aware policies
This is the foundation of Zero Trust.
Step 3: Implement Identity-Defined Networking
Move away from IP-based access and toward identity-based connectivity.
CSOI enables this by binding access policies to:
- Users
- Devices
- Roaming contractors
This ensures that access decisions are dynamic and context-aware.
Step 4: Deploy Microsegmentation
Segment networks into smaller, isolated zones.
This limits:
- Lateral movement
- Blast radius of breaches
- Unauthorized communication between systems
CSOI simplifies this with point-and-click policy management instead of complex firewall rules.
Step 5: Gradually Decommission VPN Access
As ZTNA policies are implemented:
- Reduce reliance on VPN gateways
- Transition users to application-level access
- Retire legacy infrastructure
This phased approach minimizes risk and disruption.
The Future of Secure Access: Beyond VPNs
The move away from VPNs is not just about replacing a tool. It is about adopting a fundamentally different security model.
Organizations that continue to rely on VPNs will face:
