The Department of Homeland Security (DHS), through the Cybersecurity and Infrastructure Security Agency (CISA), is expected to recompete its Enterprise Engineering and Operations Support Services (CEEOSS) requirement. This supports CISA’s Office of the Chief Information Officer (OCIO) in establishing and operating a modern, secure enterprise IT environment across CISA’s Mission Enabling Offices and six Divisions.

CEEOSS spans five functional areas:

  • Technology Evaluation and Integration
  • Enterprise Technology Services and Solutions Strategy and Architecture
  • Technical Solutions, Engineering, and Implementation
  • Operations and Maintenance Support
  • Program/Project Management.

The work covers network, identity and access management, mobility, asset management, imaging, application and systems development, collaboration, cloud hosting, and communication services. All documented using the ITIL v3 framework.

It should be noted that CISA refreshed its market research with a Sources Sought Notice, posted in December 2025 which supports their mission to identify additional companies to support these objectives. Sev1Tech LLC is currently the incumbent.

Also, the cleared-talent requirement is the key variable to watch. CISA requires a Top Secret facility clearance and TS/SCI access, so firms with proven enterprise IT engineering and O&M past performance, FedRAMP and DHS 4300A experience, and a pipeline of cleared personnel will be best positioned when the RFP lands. The forecast points to a mid-2026 solicitation, so now is the time to build teams, document past performance, and position against the incumbent.

WHY CEEOSS MATTERS

CISA’s OCIO has historically managed networks and systems individually within each Division and Mission Enabling Office. CEEOSS provides the engineering and operations backbone to consolidate those into enterprise capabilities, modernizing infrastructure, evaluating emerging technologies, migrating to hybrid cloud, and continually improving the performance, security, and availability of enterprise IT services.

The recompete reflects an expanded scope above the original requirement, driven by congressional direction such as the Cyber Incident Reporting for Critical Infrastructure Act of 2022 (CIRCIA), OCIO mission adjustments, AI initiatives, and other DHS and CISA strategic priorities. The work touches architecture, engineering, Tier 3 escalation, configuration and change management, ATO/security authorization, and the full range of O&M—making it a durable, mission-critical engagement at the heart of the nation’s cyber defense agency.

WHO SHOULD CONSIDER CEEOSS

CEEOSS is designed for firms experienced in delivering enterprise IT engineering and operations to federal environments. Firms with the following capabilities should assess their fit now:

  • Enterprise architecture and engineering: network, IAM, mobility, cloud, and collaboration design across an ITIL v3 framework
  • Technical implementation: secure engineering, Tier 3 escalation, change/configuration management, and transition to operations
  • Operations and maintenance: service desk, monitoring, patch and vulnerability management, disaster recovery, and asset management
  • Cloud and security: FedRAMP, DHS 4300A, NIST SP 800-53 rev 5, FIPS 140-2/3, and Authority to Operate (ATO) experience
  • Program management: PMP- and ITIL-certified leadership, Agile/Scrum delivery, and DHS reporting cadence
  • Cleared personnel: a Top Secret facility clearance and the ability to staff TS/SCI-eligible engineers and architects

HOW OST CAN HELP

With a solicitation release forecasted for mid-2026 and award targeted for late summer 2026, pre-solicitation activities now strengthen PWin. OST supports firms pursuing complex DHS, CISA, and federal enterprise IT engineering and operations contracts with:

  • Bid/no-bid assessment: evaluating your engineering and O&M capabilities, cleared-personnel pipeline, key personnel qualifications, and past performance against CEEOSS requirements
  • Capture planning: developing win themes and positioning relative to the incumbent, Sev1Tech
  • Teaming strategy: identifying partners to strengthen coverage across architecture, cloud, security, and O&M
  • Past performance strategy: documenting relevant enterprise IT and DHS/CISA experience and preparing strong Past Performance Questionnaires (PPQs)
  • Proposal development: technical approach, staffing and level-of-effort plans, transition-in approach, and quality control plan in accordance with solicitation requirements

If you are evaluating whether CISA’s CEEOSS opportunity aligns with your firm’s capabilities or need support with your proposal delivery, we are happy to help you determine if you can benefit from this $100M+ solicitation.
