Keep your firewall. Extend your WAN.
Lira-VPN helps enterprises keep the next-generation firewall they already trust while adding a secure, resilient WAN overlay across MPLS, Internet and 4G/5G — so branches stay encrypted, visible and governed by the same policy.
WHY IT MATTERS
Failover should never create a security downgrade.
The proposition is deliberately simple: keep the controls you already have, connect every site through a secure overlay, and maintain the same security posture whether a branch is running on MPLS or has moved to LTE. Resilience is added to the WAN; the security investment is preserved.
Keep the firewall investment you already trust
Lira-VPN complements the next-generation firewall already in place, extending policy, inspection and visibility across the distributed WAN instead of replacing what works.
Preserve security when MPLS fails over to LTE
Branches stay under the same security posture when the transport changes, so failover does not become a security downgrade.
See health, failover and recovery in one view
Network and security teams gain the telemetry they need to understand path changes, performance and branch availability in context.
THE ARCHITECTURAL PRINCIPLE
“A change in WAN path must not result in a change in security posture.”
WHAT LIRA-VPN ADDS
A secure WAN overlay that complements the next-generation firewall.
Capabilities added to the network you already operate — not a second security stack.
Encrypted inter-site connectivity
Corporate traffic between sites travels encrypted across MPLS, Internet and 4G/5G, whatever transport each location actually has.
Controlled, policy-consistent failover
Connectivity moves off an unavailable or degraded path with security policy intact, using observed link health, latency and packet loss to select the path.
Branch segmentation & least privilege
Branch-to-branch communication is limited to documented business need, so a compromise in one location does not automatically reach the whole network.
WAN & security telemetry
Jitter, packet loss, reconnects and tunnel health are surfaced for network and security teams, and can be correlated into existing SIEM and SOC workflows.
Integration, not duplication
The overlay works with the existing next-generation firewall rather than duplicating its controls — policy, inspection and logging remain where they are.
Carrier independence
Any combination of MPLS, 4G/5G and commercial broadband can carry the overlay, without lock-in to a single telecommunications provider.
Consistent posture on every path
Segmentation, access restrictions and inspection requirements do not change when the underlying transport changes.
A practical rollout model
Pilot, validation and staged deployment — onboarding branches in phases with verified routing and rollback at each step.
INVESTMENT PROTECTION
We are not proposing to replace your existing security infrastructure.
We are proposing to make the security infrastructure you already have more effective across the entire distributed enterprise.
- Existing next-generation firewall (NGFW)Proven security enforcement, custom rules and licensed threat engines remain intact.
- Existing IDS / IPS systemsThe mature signatures and operational models your security team already relies on are reused.
- Content & URL filteringEstablished corporate acceptable-use policies and web classifications are preserved.
- Endpoint security & EDRThe overlay works alongside the endpoint agents already deployed on user devices and servers.
- Identity & directory servicesIt interoperates with existing directory services, federated identity and multi-factor authentication.
- Current carrier MPLS linksHigh-SLA circuit contracts are retained while confidentiality is added through encryption.
No rip-and-replace, no duplicate licensing and no second management plane: the overlay carries what you have across more paths, under the same policy.

BUSINESS OUTCOME
Connected. Secure. Visible. Resilient. Recoverable.
Lira-VPN is positioned as the secure WAN foundation for enterprises that want to extend cybersecurity investment across every site without replacing the controls they already own.
Management buys continuity of corporate connectivity, encrypted communication across infrastructure the enterprise does not fully control, less dependence on one carrier, visibility of branch and WAN health, and fewer manual interventions when connectivity changes.
- Connected branches without sacrificing control.
- Encrypted transport across the enterprise WAN.
- Consistent policy whether the link is MPLS or LTE.
- Improved resilience, observability and recoverability for distributed operations.
Where this fits
Lira-VPN is the secure connectivity layer of a wider security architecture. Firewall, identity, endpoint, SIEM and SOC capabilities remain separate, complementary layers — see the security positioning.
