Hybrid SD-WAN Solutions
One Intelligent Network. Multiple Connectivity Paths.
QSAT designs and integrates Hybrid SD-WAN solutions that combine fibre, broadband, 4G/5G and satellite connectivity into a resilient enterprise network architecture.
By intelligently managing multiple WAN connections, organizations can improve application performance, connectivity resilience and network visibility across offices, remote sites, vessels and geographically distributed operations.
When One Connection Isn't Enough
Modern organizations increasingly operate across offices, remote sites, offshore environments and mobile assets.
A single connectivity provider or network path may not always provide the availability, performance or geographic reach required by every location.
Hybrid SD-WAN enables organizations to bring multiple connectivity technologies together and manage them through a unified network architecture.
Multiple Connectivity Options
Combine different WAN technologies according to location and requirements.
Network Resilience
Use alternative connectivity paths when a primary connection becomes unavailable.
Application Performance
Route traffic according to application and network conditions.
Centralised Visibility
Monitor distributed connectivity and network performance from a unified architecture.
What Is Hybrid SD-WAN?
Hybrid SD-WAN combines software-defined networking with multiple connectivity technologies.
Instead of relying on a single WAN connection, an organization can use different network paths and apply policies that determine how traffic should be routed.
The SD-WAN layer can apply policies based on
- Application
- Link availability
- Performance
- Latency
- Bandwidth
- Business priority
- Security policy
Bring Multiple Connectivity Technologies Together
QSAT can help organizations build hybrid WAN architectures using the most appropriate connectivity options for each location. Availability varies by site, so each design is based on what is available and suitable for that location.
Fibre
High-capacity terrestrial connectivity for locations where fibre is available.
Broadband
Cost-effective primary or secondary connectivity for suitable locations.
4G / 5G
Mobile and wireless connectivity for offices, field operations and backup paths.
LEO Satellite
Low-latency satellite connectivity for remote and geographically challenging locations.
Starlink & Multi-Orbit LEO connectivityVSAT
Satellite connectivity for remote, maritime and offshore environments.
Maritime VSAT connectivityTampnet 4G/5G
Offshore cellular connectivity for supported maritime and offshore coverage areas.
Tampnet offshore 4G/5GRelated connectivity services include Eutelsat OneWeb LEO connectivity, global Iridium satellite communications and Inmarsat satellite connectivity, which can form part of a hybrid WAN design where appropriate.
Route Traffic According to What Matters Most
Not every application has the same network requirements.
Hybrid SD-WAN can apply policies that prioritize traffic according to application, business importance and network conditions.
Critical Business Applications
Prioritise reliability and appropriate network performance.
Exact routing behaviour depends on the SD-WAN platform and its configuration.
Combine Connectivity for Greater Network Resilience
Where supported by the selected SD-WAN or bonding technology, multiple connectivity links can be used together rather than treating them as completely independent connections.
Connectivity bonding can help make use of multiple available links and provide an additional layer of resilience.
Capabilities vary between platforms — not every SD-WAN platform provides true packet-level bonding, so the approach depends on the selected platform.
Integrate Satellite Connectivity Into Your Enterprise WAN
Satellite connectivity is increasingly becoming part of enterprise WAN architectures.
QSAT can integrate satellite connectivity into hybrid SD-WAN environments where appropriate. Not every satellite service is directly compatible with every SD-WAN platform, so each combination is assessed against the requirement.
Where it is used
- Remote offices
- Offshore platforms
- Vessels
- Temporary sites
- Construction locations
- Energy facilities
- Remote infrastructure
- Disaster recovery
One WAN Architecture Across Remote Environments
Organizations with geographically distributed operations often use different connectivity technologies at different locations.
A central SD-WAN architecture can provide a consistent networking framework across these environments.
- Corporate offices
- Remote branches
- Offshore platforms
- Vessels
- Construction sites
- Industrial facilities
- Temporary project locations
Stay Connected When Network Conditions Change
Hybrid WAN architectures can provide alternative connectivity paths when the preferred connection is unavailable or unsuitable, helping maintain connectivity and support continuity by failing over automatically according to configured policies.

Security at the Heart of Your WAN
SD-WAN should work alongside an organization's wider network security architecture rather than replace it.
QSAT can integrate Hybrid SD-WAN with appropriate security technologies.
- Next-generation firewalls
- Secure VPN
- Network segmentation
- Access policies
- Secure remote access
- Cloud security services
- Identity-based policies
- Traffic inspection
Connect Branches Directly to the Cloud
Modern enterprise applications increasingly run in cloud environments.
Hybrid SD-WAN can provide a consistent framework for connecting distributed locations to cloud platforms, SaaS applications and data centres.
- Microsoft 365
- Azure
- AWS
- Google Cloud
- SaaS applications
- Private cloud
- Data centres
See Your Entire WAN From One Place
Distributed connectivity becomes difficult to manage when every site uses a different connection and configuration. A centrally managed SD-WAN architecture can provide visibility into network and connectivity behaviour, subject to the capabilities of the selected platform.
- Connectivity status
- Link performance
- Application traffic
- Bandwidth utilisation
- Network events
- Failover events
- Policy configuration

Frequently Asked Questions
Hybrid SD-WAN is a wide area network architecture that uses software-defined networking to manage more than one type of connectivity. Instead of depending on a single WAN link, an organization can combine options such as fibre, broadband, 4G/5G and satellite connectivity where available, and apply policies that determine how traffic uses each path.
