CISA Releases Guide for Post-Quantum Cryptography Adoption Amid Quantum Computing Rise

As quantum computing rapidly advances, traditional encryption methods face unprecedented risks. The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has now stepped in with a roadmap for organizations to navigate this emerging landscape. By publishing an initial list of hardware and software categories that support—or are expected to support—post-quantum cryptography (PQC) standards, CISA aims to help organizations future-proof their digital security strategies. This guidance comes in response to Executive Order 14306, issued on June 6, 2025, which directs agencies and businesses to identify and adopt widely available PQC technologies.

Quantum computing has the potential to render current public-key cryptography vulnerable, threatening the confidentiality, integrity, and availability of sensitive data. Madhu Gottumukkala, Acting Director of CISA, stressed the urgency of the transition, noting that organizations must prioritize acquiring PQC-capable products to mitigate these emerging risks.

Summary of CISA’s PQC Product Categories

The CISA list encompasses both technologies already implementing PQC standards and those in the process of transitioning toward them. Key categories include:

Cloud Services: PaaS and IaaS solutions designed to secure encrypted communication.

Collaboration and Web Software: Web browsers and messaging platforms integrating PQC for secure data exchange.

Endpoint Security: Tools like full-disk encryption software ensuring device-level protection.

Networking Hardware and Software: Infrastructure gradually adapting to PQC standards.

Identity and Access Management (IAM) Systems: Enterprise-level authentication systems moving toward quantum-resistant protocols.

The list emphasizes two core cryptographic functions:

Key Establishment: Ensures encrypted communication channels are secure.

Digital Signatures: Verifies authenticity and integrity of transmitted data.

Currently, widely available PQC-capable products include cloud infrastructure platforms, web browsers, messaging applications, and endpoint encryption solutions. Some categories, including networking hardware, IAM systems, and enterprise security software, are still in transition.

CISA also clarified that automated cryptographic discovery tools and nontraditional IT devices, such as operational technology (OT) and Internet of Things (IoT) devices, are not yet included in the list. The agency intends to update this framework regularly to reflect technological advances in quantum-resistant encryption.

What Undercode Say:

The CISA initiative is a critical step in preparing organizations for the quantum era, but adoption will require both strategic planning and tactical execution. Businesses should view the CISA list not just as a reference, but as a minimum standard for future procurement decisions. Failing to integrate PQC-capable solutions now could leave sensitive systems vulnerable to attacks as quantum computing matures.

Cloud and collaboration software providers are likely to lead the transition, given the relative ease of rolling out updates in SaaS environments. Endpoint security tools also offer quick wins, particularly for organizations with dispersed workforces. However, networking hardware and IAM systems present more complex challenges. Upgrading these systems often involves significant costs, downtime, and integration risks, meaning organizations must begin planning now to avoid delays when PQC standards become mandatory.

Interestingly, the exclusion of IoT and OT devices highlights a potential blind spot. These devices are often widely deployed in critical infrastructure and industrial environments, yet they lag behind in PQC adoption. Security teams must therefore consider alternative strategies, such as compensating controls, until vendors provide compliant solutions.

From a strategic perspective, organizations should prioritize PQC adoption in phases: start with cloud and collaboration tools, then move to endpoints, and finally address network and enterprise systems. Aligning procurement policies with PQC readiness ensures that every new technology acquisition strengthens resilience against quantum-enabled attacks.

This proactive approach also positions organizations to leverage PQC not just as a defensive measure but as a competitive advantage. Clients, partners, and regulatory bodies are increasingly aware of quantum risks, and demonstrating readiness can enhance trust and market positioning.

Fact Checker Results:

✅ CISA has officially published a PQC product categories list to guide organizations.
✅ The list includes cloud services, collaboration software, endpoint security, and networking hardware/software.
❌ IoT and OT devices are not currently included in the PQC framework.

Prediction:

✅ Within the next 2–3 years, PQC adoption will become a regulatory expectation for federal agencies and large enterprises.
✅ Vendors lagging in PQC readiness may face competitive and compliance pressures.
✅ The inclusion of IoT and OT devices in PQC standards will likely accelerate as quantum threats become more tangible.

This structured guidance from CISA positions organizations to start navigating the quantum challenge proactively, reducing risks and ensuring encryption strategies remain robust in the face of transformative technological change.
