SASE & SD-WAN Strategy, Implementation, & Managed Services
Architect a unified fabric that connects users, apps, and sites, securely and intelligently.
Why SASE + SD-WAN Matter
Modern enterprise environments are distributed, dynamic, and cloud-native. Yet, too many networks are still centralized, static, and brittle. Relying on legacy WAN and security architectures slows performance, limits visibility, and inflates operational overhead.
Secure Access Service Edge (SASE) and Software-Defined WAN (SD-WAN) converge connectivity and security into a unified fabric, enabling direct-to-cloud access, dynamic traffic steering, and policy enforcement based on identity, not just location. But implementation isn't just plug-and play. Design, integration, and operational control are what separate true value from vendor shelfware.
IVI helps you defined, deploy, and manage SASE and SD-WAN architectures tailored to your environment, aligning infrastructure, policy, security, and user experience into one cohesive strategy.
Key Business Objectives:
- Eliminate backhaul and central bottlenecks across remote and hybrid environments
- Secure application access across cloud, edge, and on-prem workloads
- Apply consistent policy based on user identity, posture, and location
- Optimize user experience with dynamic path selection and real-time telemetry
- Reduce tool sprawl by consolidating edge routing, firewall, and secure access
-
What IVI Delivers
Strategy & Architecture Alignment
We start by mapping your current WAN and security environment: traffic flows, branch connectivity, policy enforcement, and visibility gaps. We define a roadmap for unifying these with SASE and SD-WAN, based on user experience goals and infrastructure realities.
-
Platform Selection & Validation
We help you assess and select the right-fit platform, whether that's Velocloud from Arista, Cato, or integrating SSE providers like Zscaler or Prisma Access. We emphasize performance, policy flexibility, operational simplicity, and integration with your existing ecosystem (e.g. firewalls, IdP, logging).
-
Solution Design & Implementation
We build and deploy your edge architecture:
-SD-WAN overlays, circuit failover, and traffic segmentation
-Cloud gateway and SSE routing architecture
-IdP, firewall, and telemetry integration
-High availability, rollback paths, and real-world performance validation
-
Cutover & Optimization
Rollout is phased to control risk. Whether site-by-site, app-by-app or user group, we baseline performance, monitor real-time behavior, and tune policy and routing for actual usage.
-
Co-Managed & Fully Managed Services
Post-deployment, we offer co-managed or fully managed services that monitor health, surface issues, update policy, and drive continuous performance and security optimization, all while reducing your internal operational burden.
How IVI Integrates with Key Platforms
Arista Edge (Velocloud)
Strengths: Proven SD-WAN foundation, rich routing control, deep observability, best-in-class circuit failover
IVI integrates with Arista's broader data center and campus stack, tunes overlay routing, and implements policy-based orchestration with SSE
Cato Networks
Strengths: Unified SD-WAN + SSE, global private backbone, simplified management
IVI streamlines site deployments, identity policy mapping, and real-time traffic steering.
Zscaler Internet Access (ZIA) / ZPA
Strengths: Cloud-native SSE, deep integrations with identity and posture engines
IVI integrates SD-WAN edge routing with Zscaler's POPs, policy zones, and telemetry
Prisma Access
Strengths: Tight alignment with Palo Alto NGFWs and Panorama, full-stack SASE
IVI helps extend your NGFW policies to the edge, validates performance SLAs, and integrates with Prisma SD-WAN or other third-party routing.

Frequently Asked Questions
What's the difference between SASE & SD-WAN?
SD-WAN optimizes routing and connectivity across WAN links. SASE (Secure Access Service Edge) adds cloud-delivered security controls like ZTNA, SWG, CASB, and DLP, all integrated into the traffic path. SASE combines performance and security under one policy framework. We help you design and deploy both as a unified system, not as disconnected tools.
Which platforms does IVI recommend or deploy for SASE?
We align platform recommendations to your goals. We often deploy:
- Arista CloudEOS for deterministic routing and cloud connectivity
-Broadcom VeloCloud for mature SD-WAN with QoS and on-prem integration
Cato Networks for organizations seeking full-stack SASE in one platform
We also integrate best-of-breed SSE providers (like Zscaler or Palo Alto) where inline security needs exceed the native stack.
Do I need to replace my existing firewall or VPN to use SASE?
Not immediately. SASE can run in parallel to existing infrastructure, with phased cutovers. Over time, many clients consolidate or retire VPNs, MPLs, or branch firewalls as their SASE deployment matures. We build a coexistence and rollback plan into every project.
How does SASE improve user experience?
By routing traffic to cloud, SaaS, and private apps via cloud onramps and enforcing policy in the cloud, not the data center, SASE reduces latency, avoids hairpinning, and privdes a more responsive, resilient user experience.
Can I use my own identity provider with SASE?
Yes. We design all SASE architectures to integrate with Azure AD, Okta, Ping, or on-prem AD for identity-aware access and posture-based policy enforcement. We also integrate MDM and endpoint trust signals where required.
What about multi-cloud or hybrid environments?
We build vendor-neutral architectures that span public cloud, private DCs, and SaaS. Whether using CloudEOS, VeloCloud, or Cato, we ensure your control plane spans all environments with consistent access, routing, and security enforcement.
How long does a SASE implementation take?
It varies. We typically see pilot deployments within 4-6 weeks, with phased cutovers completed in 8-12 weeks. Complexity, vendor selection, and change management play a role. IVI scopes every rollout to include telemetry validation, rollback paths, and real-world feedback.
Can I integrate SASE with my existing observability tools?
Absolutely. We ensure data and health metrics flow into your SIEM, NOC dashboards, or analytics platforms, whether vendor-native or custom. Observability is not optional, it's foundational to how we operate.
