Preparing for the Post-Quantum Era: A Call to Action (2026-09-03)
CISA and the G7 Cyber Security Working Group published a strategic advisory urging organizations and governments to transition to post-quantum cryptography (PQC). The advisory outlines five priorities for adoption, including raising awareness, developing national strategies, advancing R&D, fostering partnerships, and integrating PQC into procurement. The goal is to protect sensitive data and critical assets from future quantum computing threats.

What Happened
CISA and the G7 Cyber Security Working Group published a call to action urging organizations and governments to prepare for the post-quantum era. They highlight the need to transition to post-quantum cryptography (PQC) to protect sensitive data, authentication systems, and critical assets from emerging quantum computing threats. The advisory outlines five priorities for a successful transition: raising awareness, developing national strategies, advancing R&D, fostering public-private partnerships, and integrating PQC into cybersecurity requirements and procurement processes. Organizations should consider evaluating their cryptographic dependencies and beginning planning for PQC adoption.

Detection Engineering Assessment
| Dimension | Rating | Rationale |
|---|---|---|
| EDR Visibility | None | The article is a strategic advisory and does not discuss endpoint detection or threat activity. |
| Network Visibility | None | The article does not discuss network detection or threat activity. |
| Detection Difficulty | N/A | The article does not provide technical detection guidance. |
Hunting Hypotheses
| Hypothesis | Telemetry | ATT&CK Stage | FP Risk |
|---|---|---|---|
| Consider hunting for cryptographic algorithms in use within the environment that are known to be vulnerable to quantum attacks (e.g., RSA, ECC) to establish a baseline for PQC migration planning. | Network traffic analysis, endpoint cryptographic library usage logs, application configuration files | Defense Evasion | High - Standard cryptographic protocols are ubiquitous and legitimate; identifying quantum-vulnerable instances requires application-level context. |
Control Gaps
- Standard cryptographic inventories may not exist or may not classify algorithms by quantum vulnerability.
Key Behavioral Indicators
- Usage of RSA or ECC algorithms in long-lived data protection scenarios

Recommendations
Immediate Mitigation
- Verify against your organization's incident response runbook and team escalation paths before acting. Consider identifying critical systems and data that rely on public-key cryptography and have long-term confidentiality requirements.
Infrastructure Hardening
- Evaluate whether your organization's cryptographic architecture can be updated to support hybrid or post-quantum cryptographic algorithms.
- Consider integrating post-quantum cryptography requirements into procurement processes for new hardware and software acquisitions.
User Protection
- Consider raising awareness among security teams and application owners about the timeline and impact of quantum computing threats on current cryptographic standards.
Security Awareness
- Consider incorporating post-quantum cryptography awareness into existing security training programs for architects and developers.
