Post Quantum Cryptography (PQC)

Quantum computing will make existing encryption methods obsolete, and sensitive data vulnerable. Agencies need to start preparing now. Post-Quantum Cryptography (PQC) is a proactive shift in encryption standards designed to withstand the future threat of quantum computing. The US Government requires modern cryptographic assurance to defend against emerging threats, including quantum computing.  PQC ensures resilience with new, hardened cryptographic algorithms. ATG delivers ACDI-aligned solutions that automate discovery, inventory and risk scoring while advancing post-quantum cryptographic resilience with hardened algorithms designed to replace legacy public-key systems like RSA and ECC.

Why It Matters for Mission Readiness

  • Quantum Threat Landscape: Nation-states are investing in quantum computing to target traditional encryption.

  • Harvest Now, Decrypt Later: Sensitive data stolen today could be exposed in the quantum future.

  • Compliance Driver: OMB M-23-02 mandates cryptographic system inventories to support quantum transition.

NIST-Approved PQC Standards

  • CRYSTALS-Kyber: Key exchange and encryption

  • CRYSTALS-Dilithium: Digital signatures

  • FALCON / SPHINCS+: Backup signature schemes

Cryptographic System Inventory (M-23-02)

Post-Quantum Cryptography: Mission-Ready Security for a Quantum Future ATG prepares federal, defense, and civilian agencies for the next generation of cyber threats by designing cryptographic strategies built on resilience, readiness, and compliance. As quantum computing evolves, so must your encryption

What We Deliver

Cryptographic System Inventory (M-23-02): Comply with federal mandates by conducting a full inventory of all cryptographic assets.

  • Asset Discovery and Crypto Function Detection: Identify systems, endpoints, and cloud assets. Rapidly identify quantum- vulnerable algorithms, ciphers, protocols, and certificates across endpoints, cloud services, and network devices

  • Protocol & Algorithm Mapping: Flag outdated methods (RSA, SHA-1, ECC) and map compliant alternatives.

  • Reporting & Documentation: Generate NIST/CIO-compliant reports.

  • Remediation Roadmap: Build a path toward post-quantum algorithms with built-in crypto-agility.

Post-Quantum Readiness:

  • Deploy NIST-selected algorithms like CRYSTALS-Kyber and CRYSTALS-Dilithium

  • Build drop-in cryptographic replacements for hybrid, on-prem, and cloud systems

  • Secure sensitive workloads against “harvest now, decrypt later” threats

Our Approach:

We architect your cryptographic modernization around operational timelines and compliance frameworks—not vendor hype. Our cryptography strategy starts with inventory and ends with quantum resilience

Cryptographic Analysis & Reporting

Post-Quantum Cryptography: Mission-Ready Security for a Quantum Future
ATG prepares federal, defense, and civilian agencies for the next generation of cyber threats by designing cryptographic strategies built on resilience, readiness, and compliance. As quantum computing evolves, so must your encryption.

Our Approach

We architect your cryptographic modernization around operational timelines and compliance frameworks—not vendor hype. Our cryptography strategy starts with inventory and ends with quantum resilience.

What We Deliver

  • Centralized Reporting Dashboards: Deliver live compliance views and threat exposure analytics.

  • Certificate Lifecycle Insights: Track and audit digital certificate usage, expiration, and renewal.

  • Policy Violation Alerts: Automatically detect deprecated ciphers or misconfigured encryption practices.

  • Regulatory Alignment: Tailor reports to meet the needs of CIO Council submissions, FISMA audits, and NIST reviews.

  • Post-Quantum Readiness

    • Deploy NIST-selected algorithms like CRYSTALS-Kyber and CRYSTALS-Dilithium​

    • Build drop-in cryptographic replacements for hybrid, on-prem, and cloud systems

    • ​Secure sensitive workloads against “harvest now, decrypt later” threats

Cryptographic Governance

Policy-Driven, Mission-Ready Cryptographic strategy isn’t just about tech—it’s about governance. ATG helps agencies establish repeatable, enforceable controls that ensure cryptographic integrity across every asset, environment, and lifecycle stage.

What We Deliver

  • Policy Automation
    Define approved algorithms, key lengths, and protocols. Enforce them through automated controls and role-based access policies.

  • Key Lifecycle Oversight
    Establish clear processes for secure key generation, rotation, revocation, and recovery aligned with FIPS 140-3 and NIST SP 800-57.

  • Governance-Driven Workflows
    Integrate cryptographic checks into procurement, DevSecOps pipelines, system changes, and operational reviews.

  • Audit-Ready Assurance
    Maintain clear documentation, logs, and evidence trails to satisfy internal stakeholders, external auditors, and compliance mandates.

Our Approach

We integrate cryptographic governance into your broader cybersecurity and operational strategy—ensuring security is never siloed.

Cryptographic Sovereignty & Agility

Cryptographic Sovereignty & Agility — Control It, Evolve It In a post-quantum world, encryption must not only be strong—it must be sovereign and adaptable. ATG empowers agencies to maintain full control over their cryptographic stack while enabling rapid transitions when standards evolve or threats emerge

Our Approach

ATG doesn’t just modernize encryption, we build crypto systems you own, understand, and can evolve without compromise.

What We Deliver

  • Sovereign Control
    Ensure cryptographic operations are governed internally, using U.S.-certified algorithms, locally hosted key infrastructure, and no foreign software dependencies.

  • Algorithm Agility
    Deploy architectures that allow rapid algorithm swaps across systems—without downtime, recoding, or reauthorization cycles.

  • CI/CD Integration
    Embed cryptographic policies and updates into DevSecOps workflows to stay compliant and future-ready across mission-critical pipelines.

  • System Resilience
    Future-proof sensitive systems by supporting dynamic encryption updates as part of Zero Trust and hybrid cloud frameworks.
