SD-WAN, SASE, and ZTNA Solutions with Expert Design, Delivery, and Co-Managed Services

Secure Access Service Edge (SASE): Converging Networking and Security

As organizations embrace cloud applications and support distributed workforces, traditional network architectures struggle to meet evolving demands. Secure Access Service Edge (SASE) addresses these challenges by integrating networking and security functions into a unified, cloud-native service.

What is SASE?

SASE combines Software-Defined Wide Area Networking (SD-WAN) with comprehensive security services—including Secure Web Gateway (SWG), Cloud Access Security Broker (CASB), Firewall-as-a-Service (FWaaS), and Zero Trust Network Access (ZTNA)—delivered from a globally distributed cloud platform. This convergence enables consistent, secure access for users, regardless of location or device.

Why Intelligent Visibility Recommends Cato Networks

Each use case benefits from a cohesive platform that handles both the security inspection and the traffic routing logic. That’s where Cato’s unified architecture—and iVi’s ability to deploy and manage it—adds long-term value.

Making the Transition to SASE: A Practical Path Forward

Adopting SASE doesn’t require a full rip-and-replace of your existing infrastructure. At Intelligent Visibility, we help clients evolve toward SASE through a phased, strategic approach that minimizes disruption while delivering early wins.

Here’s how we typically guide the transition:

  • Start with SD-WAN: If you haven’t already, replace traditional MPLS or router-based WAN with a software-defined underlay that can support direct-to-cloud connectivity and dynamic routing.
  • Secure High-Value Access: Next, introduce ZTNA and SWG capabilities for remote users or cloud workloads—high ROI areas that benefit from immediate visibility and control.
  • Expand and Consolidate: Over time, centralize more of your security stack into the SASE platform, retiring legacy appliances and reducing operational complexity.

Software-Defined WAN (SD-WAN): Performance, Flexibility, and Control

As enterprises shift to cloud-first strategies, adopt hybrid work models, and increase their reliance on SaaS applications, traditional WAN architectures often become a constraint. SD-WAN offers a more agile, cost-effective, and intelligent approach to network connectivity, designed to meet today’s performance and security demands head-on.

What is SD-WAN?

SD-WAN decouples the control and data planes from legacy WAN hardware, allowing traffic to be dynamically routed over multiple connection types (MPLS, broadband, LTE/5G). It replaces static, router-based architectures with software-defined policies, enabling centralized management, improved application performance, and rapid deployment across sites.

Zero Trust Network Access (ZTNA): Secure Access Without Borders

Modern enterprises can no longer rely on the outdated idea of a trusted perimeter. With users working from anywhere and applications residing in multiple clouds, securing access based on location or device alone is no longer sufficient. Zero Trust Network Access (ZTNA) provides a smarter approach: trust no user or device by default, and verify every request dynamically, every time.

What is ZTNA?

ZTNA replaces traditional VPNs with a model that grants access to applications based on identity, device posture, location, and risk signals — not network location. Unlike legacy access models, ZTNA does not expose internal IPs or network paths, significantly reducing the attack surface. Access is brokered through a policy engine that enforces least-privilege and segmentation down to the user and application level.

ZTNA is a foundational component of modern Secure Access Service Edge (SASE) architectures and can be deployed standalone or integrated within a broader platform.

SASE | SD-WAN | ZTNA FAQs

What is the difference between SD-WAN, SASE, and ZTNA?

SD-WAN optimizes wide area network performance by intelligently routing traffic across multiple links. SASE (Secure Access Service Edge) combines SD-WAN with cloud-delivered security like firewalls, secure web gateways, and CASB. ZTNA (Zero Trust Network Access) replaces traditional VPNs by enforcing identity-based, per-application access controls.

How does Intelligent Visibility deliver SD-WAN and SASE solutions?

We design and deploy best-of-breed solutions using platforms like CATO SASE, VeloCloud, CloudEOS, ZScaler and Prisma SD-WAN. We tailor each deployment to your environment, and offer co-managed services for long-term support, observability, and policy tuning.

What problems does SD-WAN solve?

SD-WAN improves application performance by dynamically routing traffic based on real-time conditions. It reduces dependency on MPLS, cuts circuit costs, and makes it easier to manage branch connectivity across cloud and hybrid environments.

Why is ZTNA better than traditional VPN?

ZTNA enforces access based on user identity, device posture, and context—unlike VPNs, which provide full network access once connected. ZTNA offers more granular control, better security, and a smoother user experience, especially for remote and hybrid workers.

Can I migrate from my current firewall/VPN to SASE and ZTNA in stages?

Yes. We specialize in phased migrations that integrate with your existing infrastructure. Our architecture allows you to introduce SASE and ZTNA capabilities gradually—minimizing disruption while modernizing your edge security model.

What ongoing support do you offer?

We provide co-managed support models that include configuration management, incident response, policy updates, and lifecycle management. With our Aegis IR, CM, and LCM services, we help your team stay ahead of change and security needs without adding headcount.

Is SD-WAN secure on its own?

SD-WAN improves routing and failover, but it doesn’t include full security controls. That’s why SASE—which combines SD-WAN with cloud-delivered security services—and ZTNA are critical for a complete secure edge strategy.
