Building a TKG Compliant Provider Network for CHEMPARK

Challenge

Compliance with legal and regulatory requirements while ensuring technical and organizational interoperability

Solution

BSI- and TKG-compliant network deployment and operation by Conneqtive, a provider registered with the Federal Network Agency (BNetzA)

  • KRITIS- and defense-resilient data transmission

Bayer’s in-house IT operated an organically grown network for a single entity (Bayer AG). With the spin-off and IPO of Bayer business units (Covestro, CURRENTA, Lanxess), and 70+ new companies settling in the CHEMPARK, the physical division of real estate and networks became mandatory, but was no task for Bayer IT.

No security at the CHEMPARK sites

The security of networks and services could no longer be guaranteed in accordance with § 164 et seq. of the Telecommunications Act (TKG).

Lack of capacity and availability

When Bayer's internal IT operations were outsourced, the operator was lost.

Outdated infrastructure

The infrastructure, which had evolved over time, no longer met the latest technical standards for structured campus cabling in accordance with EN 50173.
