The old enterprise formula for secure remote access was straightforward: connect through a VPN and prove your identity with a hardware token. That model still matters, but the market around it has become far more fragmented as remote and hybrid work, cloud services, and stricter security expectations push companies toward broader identity and access stacks.
Data from Aberdeen’s recent study captures that shift. Secure remote access now reaches a much larger share of employees than it did a quarter-century ago, while the number of tools used inside a single organization has expanded sharply. What was once a relatively narrow architecture is now a layered system of connectivity controls, identity services, device checks, and cloud-delivered security.
Why the old model is no longer enough
VPNs were built for a different enterprise perimeter. They worked best when most applications sat inside a corporate network and most remote users were a limited group, often senior staff or specialized workers. Once authenticated, users were effectively brought onto the internal network, which made sense in an era when internal systems were the center of gravity.
That assumption has weakened. Employees now connect from many locations, often from personal or lightly managed devices, to applications spread across data centers and multiple cloud platforms. In that environment, broad network access can create unnecessary risk. Security teams increasingly want access to be narrower, more conditional, and continuously evaluated rather than granted in a single step at login.
The rise of layered access and identity controls
Aberdeen’s findings suggest enterprises are not replacing one standard with another single standard. They are assembling portfolios. On the access side, categories such as zero trust network access, security service edge, secure access service edge, and cloud desktops are gaining ground alongside older tools such as VPN, Active Directory, RDP, and SSH.
The same pattern appears in identity. Passwords remain entrenched, even as organizations try to reduce their role. MFA, single sign-on, identity provider integration, password managers, digital certificates, and adaptive authentication are being added on top. That reflects a basic reality of enterprise security: older systems rarely disappear on schedule because they are tied to legacy applications, compliance requirements, and user habits.
More choice brings more protection and more complexity
This diversification has clear advantages. Zero trust models can limit users to specific applications instead of entire networks. Adaptive authentication can raise requirements when a login appears risky. SSO and identity-provider integration can improve user experience while giving administrators stronger centralized control. Cloud-delivered security services can also help organizations support a distributed workforce without routing all traffic back through a corporate hub.
But the tradeoff is complexity. Each added layer introduces integration work, policy design, operational overhead, and vendor management. Costs can rise even when security improves. Many companies now face a practical problem that is less about whether to modernize than how to keep a mixed environment manageable while old and new technologies coexist.
What the market is signaling now
The clearest message from the current landscape is not that VPN and MFA are finished. It is that they are no longer the whole story. Enterprises are moving from a model centered on trusted network access to one centered on verified identity, device posture, application-specific controls, and cloud-based enforcement.
For buyers and security leaders, that makes flexibility more important than purity. The vendors with the strongest position may be those that can support the installed base companies still depend on while also offering a credible path toward ZTNA, SSE, SASE, and more adaptive forms of authentication. Remote access security is changing quickly, but it is changing by accumulation as much as replacement.
