Secure global corporate networks (WAN) with IP VPN

The foundation of the IP VPN IntraSelect solution by T-Systems is a managed VPN based on MPLS (multi-protocol label switching). It enables the prioritization of crucial applications and guarantees secure access to centralized applications and multi-cloud connections.

MPLS-based site linkage

The IP VPN IntraSelect service by is a modular toolset of connectivity solutions for site coupling, mobility and extranet. IntraSelect Fixed Connect is especially suited to connecting medium-sized and large company sites via MPLS and in any situation that demands high availability, security and transmission quality.

Cost-effective connection of small sites

IntraSelect Remote Connect connects branches, home offices and mobile employees with the
company network securely.

Fast, high-performance connection of various cloud platforms

Dynamic cloud sourcing is becoming increasingly important for IT strategies. However, companies often underestimate the complexity of achieving a secure, high-performance connection between VPN and the relevant cloud services. IntraSelect Cloud Connect is a modular cloud gateway that connects a company network to a company VPN quickly, securely and in line with the requirements of the relevant private or public cloud provider. As a result, it offers a simple and flexible solution for integrating, swapping out and consolidating cloud services.

Optimum technology mix to suit requirements

Depending on the application purpose, the main focus is often either optimum transfer performance or maximum cost efficiency. T-Systems now offers an additional alternative to established MPLS and Internet VPN platforms in the shape of Smart SD-WAN. Thanks to its centralized control and international reach, Smart SD-WAN is a highly standardized, agile VPN platform that can be used to add additional locations or network-related services virtually at the click of a mouse.
