SD-WAN
Secure connections
Sunset on legacy networks
Secure, software‑defined networking across all mediums.
Legacy networks, built on ageing technologies like MPLS, 2G/3G mobile, PSTN, and copper lines, are fast becoming a liability as they approach their UK-wide sunset in 2027. These outdated systems leave organisations exposed to escalating cyber threats when they are simply replaced by a modern digital equivalent with no protection.
Avance cuts through these challenges with agile SD-WAN, combining powerful Avance firewalls and a dynamic PKI certificate server for a secure, software-defined network overlay. With intelligent edge adaptors, Avance ensures a seamless, risk-free migration of legacy M2M and copper-based services, safeguarding your operations and with minimum disruption to your established systems and service providers.
Why choose this service?
- Seamless migration from MPLS, 2G/3G, PSTN, and copper
- Move off ageing networks ahead of their decommissioning
- Encrypted overlay with time-limited PKI certificates protect your network from cyber attacks
- Edge adaptors emulate legacy interfaces are field tested and implemented in phases
- Minimise transition risks with a carefully managed approach tailored to your environment.
- Enhanced security posture by eliminating legacy exposure points
- Reduce vulnerability to modern cyber-attacks and compliance failures
By modernising your network with Avance, you ensure secure, high-performance connectivity. Futureproof your business against impending technology sunsets by removing security risks and inefficiencies associated with outdated network infrastructures.
Secure Migration from Legacy Networks
Technical Specification
| Core | Avance datacentre orchestrates SD-WAN to edge via time-limited PKI certificates |

| Use Cases | Alarm receiving centres, monitoring providers, local government, healthcare, facilities and building maintenance, SIs |
1. Fortress
A secure environment that protects sensitive data and critical systems throughout the migration process, ensuring controlled access and high assurance.
2. Private Cloud
A dedicated Avance cloud environment where modernised applications and services are hosted once migrated from legacy systems.
3. PKI Certificates Server
Manages digital certificates, enabling strong authentication and encrypted communication between devices and services as they transition.
4. SD-WAN
Software-defined WAN that intelligently routes traffic across legacy and modern networks, maintaining performance during phased migration.
5. Fibre Network
High-speed, low-latency fibre backbone connecting clouds, data centres and security layers for a seamless migration path.
6. Mobile Networks RAN
Public mobile radio access networks supporting devices still operating via legacy mobile connectivity.
7. Certificate
A digital identity issued to validate endpoints and ensure secure, authenticated operation on the modernised network.
8. MPLS – Legacy
Traditional MPLS network still in use by many organisations; Avance enables secure bridging while migrating away from MPLS.
9. O2, Three, EE, Vodafone
Major UK mobile carriers offering multi-network coverage for devices and services dependent on legacy cellular connectivity.
10. IoT SIM
Secure SIM technology supporting IoT and M2M devices as they transition from older SIM-based networks.
11. Adaptor
Hardware used to connect older or proprietary equipment to the modern Avance platform during the migration phase.
12. Legacy M2M Equipment
Existing machine-to-machine devices still relying on legacy network standards; Avance ensures continued operation or controlled migration to the new environment.
