SD‑WAN
Hybrid Networks
Secure, software‑defined networking across any bearer circuit.
Avance SD-WAN can create a secure hybrid networks combining any bearer circuit from different suppliers. This allows the migration of legacy copper based services to current technologies and avoid introducing a point of attack for hackers. This includes upgrading terminal equipment from copper, 2G/3G to secure encrypted, modern IP services.

1. Fortress
Avance’s secure environment for protecting critical network assets during and after migration, ensuring data integrity and controlled access.
2. Private Cloud
A dedicated, isolated cloud environment where modernised services and applications are hosted as part of the migration pathway.
3. PKI Certificates Server
Manages digital certificates and authentication, enabling secure device onboarding and encrypted communication throughout the network transition.
4. SD-WAN
Software-defined WAN optimising traffic flow across both legacy and modern networks, ensuring consistent performance as services migrate.
5. Fibre Network
High-speed, low-latency fibre backbone linking cloud environments, data centres and security layers for a seamless migration path.
6. Mobile Networks RAN
Radio Access Network connectivity from major mobile operators, supporting devices and locations that still depend on mobile-based legacy systems.
7. Certificate
A digital security certificate issued to validate devices, applications or endpoints moving from legacy infrastructure to the modern platform.
8. MPLS – Legacy
Traditional MPLS circuits still in use by many organisations; Avance provides secure bridging and phased migration away from MPLS.
9. O2, Three, EE, Vodafone
Major UK mobile networks used to support IoT, M2M and remote devices reliant on legacy SIM or cellular communication.
10. IoT SIM
Modern SIMs enabling secure, scalable connectivity for IoT and M2M devices, ready to replace outdated SIM-based technologies.
11. Adaptor
A hardware adaptor allowing older or proprietary equipment to interoperate with modern Avance services during the migration process.
12. Legacy M2M Equipment
Older machine-to-machine devices still operating on legacy networks; Avance enables secure integration, lifecycle extension or migration to modern platforms.
