5 PQC Remediation Platforms That Take Programs From Discovery to Done

Post-quantum cryptography programs can no longer stop at finding vulnerable encryption. Discovery is necessary, but discovery alone does not make an enterprise quantum-safe.

Organizations still need to determine which cryptographic risks matter most, decide what should be migrated first, coordinate changes across application and infrastructure owners, select appropriate remediation strategies, validate that each fix worked, and maintain visibility as cryptography continues to change.

5 PQC Remediation Platforms That Take Programs From Discovery to Done

1. Q.security

Q.security approaches PQC remediation as an ongoing enterprise program rather than a bottom-up cryptographic inventory exercise. The Q platform is designed around a business-first methodology. Instead of beginning with a large technical discovery dataset and deciding afterward which findings matter, Q.security starts with business risk and organizational priorities. It then connects that top-down context with the enterprise's bottom-up cryptographic inventory.

That ordering is central to the platform. Q.security builds business context from information organizations already have, including application inventories, architecture documentation, security policies, business-impact assessments, public-facing information, connected internal platforms, and approved AI systems. The customer's team reviews that model, with Forward Deployed Engineers helping fill remaining gaps.

Discovery then maps cryptography across areas including repositories, cloud infrastructure, public endpoints, TLS and SSH connections, on-premises infrastructure, and endpoints. Findings are connected back to the business applications and risks established at the beginning of the program.

Q's prioritization engine weighs business impact together with compliance exposure and threat priority, including factors such as Harvest Now, Decrypt Later exposure, confidentiality lifetime, and regulatory deadlines. The result is a phased remediation plan rather than an undifferentiated vulnerability backlog.

Execution is then managed step by step. Q.security supports remediation through runbooks and ticketing integrations, with scripted and automated fixes after human approval included in its planned execution model. Findings remain open until validation confirms closure.

Q.security treats PQC as a continuous program. Discovery, prioritization, remediation, and governance operate as a recurring loop over a common system of record, giving the CISO ongoing visibility into progress while keeping the organization crypto-agile as threats, standards, and deadlines change.

2. SandboxAQ AQtive Guard

SandboxAQ's AQtive Guard combines cryptographic posture management with active policy enforcement and remediation.

Its cryptographic discovery capabilities cover multiple surfaces, including source code, binaries, cloud environments, file systems, endpoints, and network traffic. That broader coverage is designed to show both where cryptographic assets exist and how they are being used in production.

AQtive Guard then adds context around those discoveries. Its platform maps cryptographic assets to infrastructure, owners, access patterns, dependencies, and business criticality. The objective is to determine not only whether weak or quantum-vulnerable cryptography exists, but what the operational impact of changing it might be.

3. QuSecure QuProtect R3

QuSecure's QuProtect R3 approaches PQC remediation through three connected functions: Recon, Resilience, and Reporting. QuProtect Recon discovers cryptography in live network traffic and builds visibility into certificates, algorithms, protocols, cipher suites, and other cryptographic use. Rather than simply counting findings, the platform can rank legacy cryptography according to exposure.

QuProtect Resilience provides the remediation layer. One of the platform's distinguishing characteristics is its use of software encryptors and centralized orchestration to change the cryptography protecting data in transit without requiring application-level code changes for supported scenarios.

An administrator can define the desired cryptographic policy centrally. QuProtect's orchestrator distributes that policy to software encryptors, which can establish post-quantum or hybrid-protected connections while applications continue communicating through their existing interfaces.

4. IBM Quantum Safe

IBM approaches PQC remediation through a broader portfolio of technology and transformation capabilities rather than one isolated discovery product.

IBM Quantum Safe Explorer focuses on finding cryptography in application code. It identifies cryptographic APIs and artifacts, uncovers quantum-vulnerable algorithms, maps dependencies, generates CBOM information, and helps development teams identify opportunities for remediation and crypto-agility.

IBM Quantum Safe Remediator addresses the transformation side. Its remediation patterns include approaches for networks, enterprise applications, and third-party or vendor software. IBM's Adaptive Proxy can also introduce quantum-safe protection to supported communications without requiring changes to the underlying legacy application.

5. Keyfactor

Keyfactor connects PQC preparation with its broader cryptographic security, certificate lifecycle, PKI, and digital trust portfolio. Keyfactor AgileSec provides the discovery layer.

It continuously identifies cryptographic assets across code, infrastructure, endpoints, networks, cloud workloads, and related environments. The resulting inventory can include certificates, keys, algorithms, protocols, libraries, dependencies, ownership information, and contextual risk data.

Its EJBCA PKI technology supports quantum-resistant and hybrid certificates, allowing organizations to develop and test future cryptographic trust architectures. Keyfactor Command provides certificate lifecycle management, while signing products address additional parts of the cryptographic estate.

What to Look for in a PQC Remediation Platform

Enterprises evaluating PQC remediation platforms should look beyond discovery coverage and compare how each platform supports the complete transition.

Important capabilities include:

• Business context: Can cryptographic findings be connected with business applications and criticality?

• Broad cryptographic discovery: Does the platform cover the places where the organization's cryptography actually lives?

• Contextual prioritization: Can the system turn findings into a defensible remediation sequence?

• PQC expertise: Does it provide useful guidance around quantum-safe algorithms, hybrid approaches, and legacy constraints?

• Execution workflows: Can findings become assigned and trackable remediation work?

• Change controls: Does remediation account for production resilience and business continuity?

• Automation: Which migration activities can be automated safely?

• Human approval: Can sensitive cryptographic changes remain under appropriate human control?

• Validation: Does the platform confirm that remediation actually removed the risk?

• Program reporting: Can CISOs see progress, exceptions, milestones, and next steps?

• Continuous discovery: Will the inventory stay current after the initial assessment?

• Crypto-agility: Will the architecture make the next cryptographic transition easier than this one?

• Existing-tool integration: Can the platform build on the enterprise's current security, IT, PKI, development, and ticketing environment?

The objective should be a platform that helps turn PQC from an open-ended technical mandate into a structured and measurable security program.

FAQs

What is a PQC remediation platform?

A PQC remediation platform helps enterprises identify quantum-vulnerable cryptography and move it toward quantum-safe alternatives. Depending on the platform, capabilities can include cryptographic discovery, inventory, risk prioritization, migration planning, remediation guidance, workflow orchestration, automated cryptographic changes, validation, governance, and continuous cryptographic posture management.

What is the difference between PQC discovery and PQC remediation?

PQC discovery identifies where cryptography exists and which assets may be vulnerable to future quantum attacks. Remediation addresses those findings by prioritizing them, selecting appropriate migration strategies, assigning ownership, executing changes, validating closure, and continuously monitoring the environment for new or recurring cryptographic risk.

What is a Cryptographic Bill of Materials?

A Cryptographic Bill of Materials, or CBOM, is a structured inventory of cryptographic components used across software and systems. It can include algorithms, libraries, certificates, keys, protocols, and related information. A CBOM provides important visibility, but additional business and operational context is typically needed to turn the inventory into a prioritized PQC remediation program.

How should enterprises prioritize PQC remediation?

Prioritization should consider more than the type of cryptographic algorithm. Organizations can combine business criticality, confidentiality lifetime, Harvest Now, Decrypt Later exposure, regulatory context, external exposure, technical dependencies, vendor readiness, and migration complexity to determine which applications and cryptographic risks should be addressed first.

What is crypto-agility?

Crypto-agility is the ability to change cryptographic algorithms, keys, certificates, protocols, libraries, and related controls without requiring disruptive redesign every time cryptographic requirements change. For PQC programs, crypto-agility is important because the current migration is unlikely to be the last major cryptographic transition enterprises need to manage.

Can PQC remediation be fully automated?

Some remediation activities can be automated, especially where platforms control certificates, cryptographic policy, network protection, or standardized configuration. Other changes may affect applications, infrastructure, third-party products, or critical business systems and therefore require engineering work or human approval. Enterprise programs typically need a combination of automation, controlled workflows, and expert judgment.

When is a PQC remediation finding actually complete?

A finding should be considered complete when validation confirms that the vulnerable cryptographic condition has been removed or appropriately mitigated, not simply when a migration task has been marked finished. Continuous discovery should then verify that future changes do not reintroduce the same cryptographic risk.
