Award procedure without prior publication of a call for competition
Why this procedure was chosen
Following a comprehensive and competitive procurement process, a direct award to Elastic is being proposed based on the following critical factors: (i)Compliance with National Power Outage (NPO) Requirements: The procurement exercise established that only two solutions that sit high in the Gartner Quadrant, Splunk and Elastic, are capable of meeting the stringent National Power Outage (NPO) requirements. These requirements explicitly preclude the use of cloud-based SIEM solutions. Furthermore, both technologies are compatible with the selected Managed Security Service Provider (MSSP) and have readily available engineering expertise within the open market. This significantly reduces delivery risk and ensures continuity of service. (ii)Technical Recommendation and Internal Validation: The selected SOC MSSP has provided a strong recommendation in favor of Elastic, citing its suitability to meet the NPO constraints and operational needs. In parallel, the NESO Chief Security Office (CSO) has conducted an internal assessment of Elastic and confirmed it aligns with their functional and security requirements. This dual endorsement reinforces confidence in the technical and strategic fit of the solution. Furthermore, Elastic is already being used in CNI and the business for health monitoring purposes, so there is some experience in supporting it. (iii)Cost Efficiency: From a financial standpoint, Elastic is significantly more cost-effective option compared to Splunk. The estimated annual cost of implementing and maintaining Splunk is over eight times higher than that of Elastic. This substantial cost differential highlights the strong value for money achieved through a direct award to Elastic, making it the more economically viable solution. In light of the above considerations, namely compliance with critical NPO constraints, alignment with MSSP and CSO assessments, and marked cost savings, a direct award to Elastic is both justified and strategically sound.
