When multiple sites have to work as one

Companies with branches, subsidiaries or field offices face a core challenge: all sites need to be securely, reliably and quickly interconnected. Staff access central servers and applications, data flows between sites, telephony and collaboration run across locations. Classic VPN solutions are widespread but bring complexity, fragility and high maintenance effort. As demands grow, they quickly hit a wall.

Layer 3 networking: stable, secure, scalable

ITS AG delivers multi-site networking on Layer 3 – a professional network layer that offers stability, performance and scalability without the drawbacks of classic VPN tunnels. Layer 3 networking provides a clean architecture with centralised control. New sites are added without redesigning the whole topology. And when something goes wrong, troubleshooting is much easier than in nested VPN setups.

Benefits of site networking with ITS AG

  • Secure, encrypted connections between all sites
  • Stable performance for data traffic, cloud and VoIP
  • Centralised control and unified network management
  • Easy scaling for new sites or growing demand
  • Lower maintenance effort than classic VPNs
  • Personal support by ITS AG – not an anonymous helpdesk

Built for both perspectives

What secure multi-site networking means for your company

Two perspectives, one outcome: IT that carries reliably and stays transparent.

For management

  • Smooth processes across sites – no downtime from connectivity issues
  • Fewer incidents and less internal IT effort on networking
  • Better collaboration across locations
  • Future-proof connectivity that grows with your company

For IT leads

  • Clean network architecture with central routing control
  • Centralised management of all site links
  • Significantly less VPN maintenance and troubleshooting
  • Clean scaling – new sites without architectural breakage

How we work

From first conversation to ongoing operation

A clearly structured process — no hidden phases, no surprise invoices.

  1. 01

    Site and traffic analysis

    Which apps run where? How much data flows between which sites? That dictates topology and bandwidth.

  2. 02

    Topology and hardware concept

    Recommendation hub-spoke vs. full mesh, hardware list, redundancy concept — written and traceable.

  3. 03

    Per-site rollout

    Hardware install, configuration, failover test — site by site, no big-bang risk.

  4. 04

    Handover and documentation

    Full network documentation, IP plan, escalation matrix — usable also by your internal IT team.

  5. 05

    Ongoing operation

    Central monitoring, performance reports, expansion to new sites within a few weeks.

Typical use cases

Where connected sites make the biggest difference

Three constellations we see often — and how we deliver in them.

Branch network

A tax firm with 5–15 branches accesses central DATEV/client servers — every branch needs fast, secure connectivity to HQ.

Manufacturing sites

Manufacturer with plants across several states — machine data, CAD and ERP must sync between locations.

Distribution sites

Logistics provider with distribution centers — warehouse, dispatch and HQ need a uniform, secured view of inventory.

Use cases

When multi-site networking pays off most

Companies with HQ plus one or more branches

Chain businesses with centralised IT systems

Hybrid setups with office and home-office sites

Cloud-reliant organisations with centralised data

Frequently asked

What customers ask about Secure Multi-Site Networking

  • Layer 3 is the network layer where communication between separate networks – e.g. different company sites – is controlled. Compared to plain VPN tunnels, Layer 3 networking offers a more professional, stable and easily scalable connection.
