The SealingTech Defensive Cyber Operations Kit is uniquely capable of meeting the Government's operational requirements

Sealing Technologies LLC possesses the proprietary hardware configuration, engineering design, and technical expertise necessary to provide this capability. The SealingTech DCO Kit has been specifically engineered to integrate with existing Marine Corps cyber infrastructure and support operational testing requirements.

Introducing alternate hardware platforms would require significant engineering analysis, configuration changes, compatibility testing, operator retraining, and validation activities while increasing technical and schedule risk.

The Government determined that no other manufacturer provides a commercially available hardware solution that replicates the current Program-of-Record configuration while maintaining interoperability with fielded Marine Corps DCO systems. Accordingly, restricting this procurement to Sealing Technologies LLC is necessary to maintain mission readiness, ensure operational compatibility, and minimize lifecycle risk.

C. ___UNUSUAL AND COMPELLING URGENCY. The supplies or services are of such unusual and compelling urgency that the Government would be seriously injured unless the agency is permitted to limit the number of sources from which it solicits bids or proposals. Urgent requirements are supplies or services that will result in a work stoppage or are mission critical and the routine processing time would result in injury to the Government. The determination that the procurement for the above item/service is an urgent and compelling requirement is based on the following:

1. Date on which the requirement was first identified:

2. Required delivery date/period of performance:

3. Explanation of why delivery/commencement of services by the date mentioned above is required:

4. If appropriate, include any additional pertinent information.

IV. CERTIFICATIONS/APPROVALS:

A. Technical/Requirements Certification: I certify that the facts and representation under my cognizance which are included in this justification are complete and accurate to the best of my knowledge and belief.
