About This Opportunity
TranslatedThis tender concerns the provision, implementation, configuration, and management of security services, as previously advertised in the Supplement to the Official Journal of the European Union under the title "Security services (EU-437)". The procurement process utilized a negotiated procedure with prior call for competition, conducted electronically via the Negometrix/Mercell system (Ref. No. 220000 or EU 437). Four candidates were shortlisted for the award phase, with ilionx Group B.V. ultimately receiving the contract. The project involves the implementation of a Security Operations Center (SOC) and a Security Information and Event Management (SIEM) system for TenneT TSO GmbH. While the architecture is based on the established system of TenneT TSO BV in the Netherlands, significant technical and organizational adjustments are necessary to ensure secure, efficient, and compliant operation of the SOC and SIEM systems within Germany, due to differing operational models in the two countries. These adaptations to the operational model and technical architecture are crucial for guaranteeing the secure functioning of the systems for TenneT TSO GmbH. Proceeding with a new tender process would entail substantial delays, compliance risks, and economic disadvantages. Therefore, it is recommended that the required changes be implemented within the existing contractual framework through a "Letter of Change".
This is a services contract in the information and communication technology and security and defense sectors, with a focus on Cybersecurity and IT support. Located in Germany, Europe, this opportunity is open to firms and consortiums, with an estimated budget of EUR 1.

Description
Auto-translated from GermanThe tender for the provision, implementation, configuration and management of security services was published in the Supplement to the Official Journal of the European Union (available at http://ted.europa.eu) and announced as "Security services (EU-437)". The tender was based on a negotiated procedure with prior competitive dialogue. It was an electronic procurement procedure via the Negometrix or Mercell system (No. 220000 or EU 437 respectively). 4 candidates were selected for the award phase. The contract was awarded to ilionx Group B.V. The implementation of the Security Operations Center (SOC) and the Security Information and Event Management (SIEM) system for TenneT TSO GmbH is based on the already established architecture of TenneT TSO BV in the Netherlands. However, due to the different operating models in the two countries, technical and organizational adjustments are necessary to ensure secure, efficient and regulatory compliant operation of the SOC and SIEM system in Germany. The adjustments to the operating model and the technical architecture are essential to ensure the secure operation of the SOC and SIEM system for TenneT TSO GmbH. A new tender would involve significant delays, compliance risks and economic disadvantages, so the changes should be implemented within the existing contractual framework through a "Letter of Change".
