SD-WAN

Your edge-to-edge, software-defined network. Business-critical apps prioritized and accelerated, traffic encrypted end to end, operated by AI and Level-3 engineers.

Overview

One network, run for you.

Traditional WAN networks are complex, expensive, and increasingly hard to secure. Enterprises that operate globally and lean on cloud and mobile need high-performance connectivity and next-gen security at the same time, and those demands are getting harder to meet.

SD-WAN by Open Systems is purpose-built to simplify network and security operations. It delivers the full benefit of SD-WAN while reducing cyber risk, simplifying compliance and removing the headache of stitching an ecosystem together. It prioritizes and accelerates business-critical apps while making optimal use of available bandwidth. AI-run automation and Level-3 engineers, no L1, no L2, take care of your network and security operations, keeping traffic fast and resolving security issues the moment they surface.

Components of SD-WAN

Four building blocks.

Encryption & Routing

Network protection from eavesdropping, with reliable VPN routing across any provider.

Bandwidth Control

Sufficient bandwidth for critical applications, always.

Path Selection

Policy-based dynamic routing for optimal traffic control.

App Optimization

Higher performance for a better user experience.

Encryption and routing

A secure, reliable network is the basis for smooth operation of every business-relevant application. Our SD-WAN automatically encrypts and authenticates all traffic between sites across public and private networks, internet or MPLS, regardless of provider, so business-critical data stays safe and risk drops. Reliable VPN routing keeps traffic on a direct path and guarantees availability even when a path drops. A single-pass architecture decrypts and analyses VPN traffic to give business owners full application visibility.

Bandwidth control and path selection

Access lines and bandwidth vary by location and connectivity type. Bandwidth Control gives fine-grained tools and metrics to govern usage per application, per location and per connection. Path Selection adds smart load balancing and policy-based routing per application, so every app takes an optimal path and you can define per-app fallback order when connections drop or degrade.

Customer story

SD-WAN rollout to 90 sites in just six months

Kelvion, a global heat-exchange specialist, needed a scalable, high-performance WAN, and a partner to deliver it worldwide, after its outdated networks could no longer meet modern demands.

Application optimization

With everyone connecting on the move, constant file sharing and a sheer number of applications, bandwidth can choke at peak hours in important locations, and apps slow down under congestion, packet loss or latency. Application Optimization tackles both: it cuts bandwidth usage with caching and compression, and accelerates slow apps through protocol optimization.

FAQ

Questions about SD-WAN.

Do we have to give up MPLS to do this?

No. Traffic between sites is encrypted and authenticated across public and private networks alike, internet or MPLS, whatever the provider. That means MPLS circuits can stay where they still earn their cost and be retired where they do not, site by site, instead of in one decision.

How is it decided which application takes which path?

By your policy, not by a default. Path selection performs smart load balancing and policy-based routing per application, and you can define the fallback order per application for when a connection drops or degrades. Bandwidth control then governs usage per application, per location and per connection, so a backup job cannot squeeze the software your business runs on.

What happens when a line degrades rather than fails outright?

That is the harder case and the one that is planned for. A path that is up but lossy still hurts real-time traffic, so degradation triggers the same per-application fallback as an outage, and application optimization absorbs part of the damage with caching, compression and protocol tuning.

Can we see what our applications actually consume?

Yes, and it is often the first surprise. A single-pass architecture decrypts and analyses VPN traffic, so there is full per-application visibility with consumption and trends, rather than a bandwidth graph per line that says nothing about which tool is responsible.

Is the encryption something we have to configure?

No. All traffic between sites is encrypted and authenticated automatically, regardless of provider or transport. That is deliberate: encryption that has to be set up by hand for every new link is encryption somebody eventually skips under time pressure.

How long does a global rollout take?

It is driven by sites and last-mile lead times rather than by the platform. As a reference point, Kelvion rolled out to 90 sites in six months. The realistic answer for your estate comes out of the assessment, and it is worth asking for that number rather than a generic one.
