The FY2027 President's Budget requests $5.9M for National Infrastructure Simulation Analysis Center, within Homeland Security's Operations and Support account. That is down 76% on the FY2026 figure of $24.4M, which is a continuing-resolution annualized figure, not an enacted appropriation.
FY2025–FY2027
| Fiscal year | Basis | Amount |
|---|---|---|
| FY2025 | enacted | $24.4M |
| FY2026 | CR annualized | $24.4M |
| FY2027 | request | $5.9M |
The prior-year column is a CR annualized figure — the rate a continuing resolution funds at, not an enacted appropriation. The two are different numbers and are not interchangeable. Bases are separate columns and are never summed into one figure.
Homeland Security discretionary budget authority
From the OMB Public Budget Database — clean, summable, and the figure to cite for an agency total. It is the whole of Homeland Security's discretionary request, not a total of the parsed lines above, and this page never adds the two together.
What this funds
NISAC works with DHS components and other Federal agencies to close strategic gaps in critical infrastructure modeling, simulation, and analysis, serving as a leading source of expert analysis and modeling for cyber and critical infrastructure security decisions.
Extracted from Cybersecurity and Infrastructure Security Agency, p. 6. Verbatim; nothing here is paraphrased.
