# CISA Requires Faster Federal Patching

CISA is tightening federal vulnerability-remediation expectations as AI accelerates vulnerability discovery beyond agencies’ ability to patch systems. Under Binding Operational Directive 26-04, agencies must remediate their highest-risk vulnerabilities within 72 hours beginning in December 2026; CISA also encourages roughly 24-hour remediation for some internet-exposed critical flaws. No specific solicitation, award, or funding amount is identified, but the directive points to potential contractor demand for risk-based prioritization, threat-intelligence integration, exploitability testing, rapid patching, and machine-readable vulnerability reporting.

- Federal contractors supporting agency cybersecurity programs should expect vulnerability-management requirements to emphasize rapid, risk-based remediation and reporting; the directive’s agency requirements do not, by themselves, establish a direct mandate for contractors.
- Companies offering vulnerability-prioritization, internet-exposed asset identification, and governed remediation automation can align offerings with the capabilities described in the signals.
- Agencies must begin meeting the three-day remediation deadline in December 2026, while CISA encourages faster response for certain exposed critical flaws.
