Open Systems —
Managed SASE, SD-WAN & ZTNA Converged on One Platform

Open Systems is positioned for distributed multinational and mid-market enterprises that want a single operator delivering SASE, SD-WAN, and ZTNA as a unified managed service rather than three separate vendor stacks. The strongest fit is multi-site enterprises across manufacturing, life sciences, financial services, and globally distributed organizations whose operating model rewards consolidating WAN and security into one platform with 24x7 expert operations baked in — particularly buyers who do not want to staff a SASE practice in-house and prefer outcome-based managed delivery.

SD-WAN as a Service from Open Systems is a fully managed engagement — design, deployment, ongoing operations, monitoring, change management, troubleshooting, and 24x7 expert support are delivered by Open Systems rather than the customer. The model fits organizations whose multi-site WAN is mission-critical but whose IT teams cannot reasonably staff a dedicated SD-WAN operations practice. Application-aware routing, QoS, link bonding, and integrated security policy are configured and operated as part of the service rather than configured by the customer post-procurement.

Open Systems SASE converges SD-WAN, Secure Web Gateway, Cloud Access Security Broker, ZTNA, Firewall-as-a-Service, and DNS security into one cloud-delivered platform — with a single management plane and a single operations team rather than separate vendor relationships per security function. The structural advantage is that policy, identity, and traffic-inspection decisions happen consistently across remote users, branch sites, and cloud workloads rather than per-product-stack. The 24x7 operations layer means policy and detection tuning is delivered as a service rather than as a product the customer installs.

Zero Trust Network Access from Open Systems replaces traditional VPN architectures — where a connected user gets broad network access — with identity- and context-aware access to specific applications, evaluated continuously rather than at session start. The model fits organizations whose distributed workforce, contractor population, third-party integrations, and OT/IT boundary make a flat-VPN posture both an attack surface and an operational burden. ZTNA is delivered as part of the broader SASE platform rather than as a separate product, so identity and policy are unified across remote access, web traffic, and SaaS.

The structural argument is operational economics — assembling SD-WAN, SASE, and ZTNA from separate vendors leaves the customer responsible for integration, day-2 operations, change management, vendor escalation across three relationships, and continuous tuning across three products. Open Systems delivers the same capability stack as one converged platform with one 24x7 operations team — meaning the customer's network and security posture moves forward continuously rather than only when internal capacity allows. The right fit is buyers who treat managed delivery as a feature rather than a fallback.

No. Your engagement is signed directly with Open Systems and Open Systems' standard service terms apply. Fibi's role is to scope your SD-WAN, SASE, or ZTNA objective against Open Systems and the most relevant alternatives — so you see how Open Systems' fully managed converged platform compares against unmanaged SASE, point-product SD-WAN, and standalone ZTNA before signing. Fibi's advisory work is provider-funded, so the comparison comes at no additional cost to your business.
