Most enterprises have already made the strategic decision to adopt Zero Trust and SASE. The debate about whether these models make sense is largely over.

Over the past few years, this strategic alignment has become visible in board discussions, regulatory guidance, and vendor roadmaps that are now largely built around identity-centric security and SASE principles. As a result, most conversations have shifted from whether to adopt Zero Trust and SASE to how to implement them in complex, hybrid environments.

Yet many security and IT leaders feel a growing frustration: despite clear strategy and significant investment, progress feels slower than expected. Complexity remains high. Visibility feels incomplete. Operations feel heavier, not lighter.

What’s going on? The answer is increasingly clear. The real challenge is no longer strategy; it’s execution.

Hybrid Is No Longer Temporary

For years, “hybrid” was treated as a transitional phase. A stepping stone toward a more cloud-centric future. That era is over.

Hybrid is now the default operating model for global enterprises. Users work from anywhere. Applications live across multiple clouds and data centers. Third-party access is routine. Branches, partners, and remote teams are all part of the same digital fabric.

Connectivity across these environments has improved dramatically. But visibility and control have not kept pace.

As environments expand, the ability to observe and manage them consistently becomes harder. Many organizations discover that what worked for centralized networks and static perimeters doesn’t scale to distributed, identity-driven access.

Hybrid complexity is growing faster than most teams’ operational capacity.

The Visibility Problem No One Talks About Enough

One of the most underappreciated challenges in modern security is not protection, it’s visibility. Many teams feel reasonably confident monitoring core applications inside traditional environments. But confidence drops quickly at the edges:

  • Remote and hybrid users
  • Multi-cloud traffic
  • Third-party and supplier access

And that’s exactly where risk is highest. The modern enterprise no longer has a clear perimeter. The edge is the enterprise. Yet this is where many organizations lack consistent observability and context.

Without unified visibility, even strong policies become harder to enforce consistently. Incident response slows down. Troubleshooting becomes fragmented. Security and networking teams spend more time correlating signals than solving problems. The real gap is operational visibility – the ability to see, understand, and act on what is happening across users, clouds, and partners in a unified way. Without that foundation, both security and troubleshooting become slower, more manual, and more reactive than they need to be.

Zero Trust Is Real, but Often Incomplete

Zero Trust adoption is real and accelerating. But fully integrated Zero Trust environments remain the exception rather than the rule. Many organizations start with ZTNA for remote users. That makes sense: it delivers quick wins in both security and user experience. The challenge comes next.

Extending Zero Trust consistently across branches, data centers, and partner ecosystems is significantly more complex. Identity alignment, policy consistency, and traffic visibility must all work together.

What often emerges is a “middle state”: modern access controls layered onto legacy architectures. Security improves in some areas, but operational complexity rises overall.

Partial Zero Trust can temporarily increase complexity before it reduces risk. That complexity usually reflects an operating model that has not yet caught up with the architecture. That’s not failure; it’s a signal that architecture alone isn’t enough. As organizations move from network-based access to identity-based access, they are not just changing technology – they are changing how access is reasoned about, managed, and operated. This shift in mindset is powerful for security, but it also makes execution harder, which is why operations matter more than intent.

The Real Constraint: Operational Capacity

When you look closely, the biggest barriers to progress are rarely budget or executive support. They are operational realities:

  • Skills shortages
  • Integration challenges with identity systems
  • Coordination gaps between network and security teams
  • The burden of running VPN and ZTNA in parallel

Legacy operating models were built for static perimeters and slower change cycles. Modern architectures demand continuous alignment across identity, policy, and traffic flows. That requires time, expertise, and sustained operational focus.

This is the SASE execution gap: complexity outpacing capacity.

Why SASE Is Becoming an Operating Model Decision

SASE was initially approached as a technology deployment. Choose a platform, roll it out, and move on. That mindset is shifting.

More organizations now recognize that SASE is not a one-time project. This shift forces organizations to be far more explicit about their operating model: who owns identity governance, who operates policy day to day, how incidents are handled across network and security teams, and what is run internally versus with a partner. Without this clarity, even well-designed SASE architectures tend to create friction between teams and slow execution rather than accelerate it. It is a continuous operating model. Policies evolve. Threats change. Environments expand. Integrations require maintenance. Secure access must be operated consistently over time, not just deployed once.

This is why co-managed and managed delivery models are gaining traction. Not as a return to outsourcing, but as a pragmatic response to operational load. The goal is not to give up control. It’s to sustain it. Organizations increasingly want to retain governance and visibility while sharing the day-to-day operational burden with a trusted partner.

What High-Performing Organizations Do Differently

Organizations that make steady progress with Zero Trust and SASE tend to share a few traits.

  • They focus on visibility before expansion. Instead of rushing to extend Zero Trust everywhere, they ensure they can observe and manage what’s already deployed.
  • They plan for the middle state. Running VPN and ZTNA in parallel is treated as a managed phase with clear criteria and timelines, not a temporary inconvenience.
  • And they align their operating model, roles, and responsibilities with realistic capacity. They evaluate what their teams can sustainably operate, not just what they can deploy.

In other words, they treat security as an operational discipline, not just an architectural goal.

The Shift from Vendor to Operating Partner

Buyer expectations are evolving. Architecture diagrams and feature lists no longer carry the same weight. Operational credibility does.

Security leaders increasingly look for:

  • Reliable 24×7 operations
  • Strong compliance and regulatory alignment
  • Clear data residency and transparency
  • Proven operational depth

The relationship is shifting from vendor to operating partner. From product delivery to shared accountability. This reflects a simple truth: sustainable Zero Trust requires continuous operations.

From Architecture to Execution

The industry is aligned on the destination: Zero Trust and SASE. The differentiator now is not who moves first, but who sustains progress.

The organizations that succeed will not be those with the most tools, but those with operating models built for long-term consistency. In a hybrid world, resilience is operational.
