Modern site-to-site without hardware VPN appliances
Link branch offices, manufacturing sites, and core data centers through encrypted mesh tunnels managed from a single control plane — no complex IKE configurations or fragile concentrators.
What teams struggle with today
- Hardware VPN appliances are expensive to scale across many sites.
- IKE-based tunnels break when NAT, CGNAT, or asymmetric routing is involved.
- Adding a new site requires coordinated firewall and routing changes everywhere.
- Limited visibility into which sites can reach sensitive production networks.
How QuadScale solves it
Deploy a QuadScale gateway at each site to advertise local LAN CIDRs. The mesh establishes optimal paths between sites with automatic NAT traversal and relay fallback, while administrators enforce which sites may communicate.
Subnet routers on-prem
Expose office and factory LANs without placing every device on the mesh individually.
High-availability gateways
Run redundant gateways for critical sites with health checks and failover.
Inter-site policy control
Allow HQ to reach branch ERP systems while isolating guest Wi-Fi segments.
Cloud extension
Extend the same mesh to VPCs and Kubernetes clusters without separate VPN stacks.
Roll out in four steps
- 01
Install site gateways
Deploy on a small VM, appliance, or existing router with outbound internet access.
- 02
Advertise local subnets
Publish LAN CIDRs and validate no conflicts with cloud or other sites.
- 03
Establish mesh paths
Confirm direct connectivity; configure relays only where firewalls block P2P.
- 04
Segment inter-site traffic
Apply policies so only authorized sites reach finance, OT, or production systems.
What you gain
- Retire aging hardware VPN concentrators at branch sites
- Add new locations without re-keying every existing tunnel
- Improve resilience with mesh paths instead of single-hub designs
- Unify on-prem and cloud connectivity under one policy model
