Post-quantum cryptography has moved beyond long-range research planning. Security leaders now need to determine where their organizations use vulnerable cryptography, which systems would create the greatest business impact if compromised, and how to sequence remediation without interrupting critical operations.
Quantum readiness assessment tools help security teams create that starting point. The strongest platforms combine cryptographic discovery with business context, ownership mapping, risk prioritization, remediation planning, and continuous monitoring.
Enterprise teams should look beyond simple scanning capabilities when comparing post-quantum cryptography assessment platforms. The right tool should provide an actionable path from visibility to quantum-safety.
Comprehensive Discovery & CBOM: Ensure the platform scans code, cloud environments, certificates, infrastructure, and endpoints to generate an actionable Cryptographic Bill of Materials (CBOM).
Business-First Prioritization: Look for tools that rank cryptographic findings based on data value, business criticality, and harvest-now, decrypt-later risk, not just generic technical severity.
End-to-End Remediation Support: Choose a solution that integrates with ticketing, assigns ownership, provides step-by-step guidance, and validates that fixes are complete.
Continuous Posture & Crypto-Agility: Select a platform that continuously monitors for cryptographic drift, keeping posture up to date as standards, threats, and vendor dependencies evolve.
Q.security provides the Q platform, a business-first PQC remediation platform designed to help enterprises achieve quantum-safety through an ongoing, CISO-owned program. Instead of beginning solely with a technical crypto scan, Q starts with top-down business risk: the applications, data, business units, and high-value assets that matter most. It then connects that context to a bottom-up cryptographic inventory, helping teams understand not only where vulnerable cryptography exists, but why specific findings should take priority.
The Q platform takes enterprises from discovery to done. It can build a crypto inventory from approved, minimum read-only access across code repositories, cloud infrastructure, public-facing endpoints, TLS and SSH connections, on-premises systems, and endpoints. Its prioritization engine weighs business impact, threat priority, confidentiality lifetime, harvest-now, decrypt-later exposure, and regulatory context. From there, Q guides remediation through runbooks, tickets, and governed workflows, keeping findings open until validation proves closure. This makes it especially relevant for organizations that need to turn quantum readiness from a technical discovery exercise into a phased PQC program with visible progress.
Business-First Prioritization: Connects business risk to the real cryptographic estate, helping teams fix the highest-risk cryptography first.
Cryptographic Discovery and CBOM Context: Builds a detailed, business-aware inventory across code, cloud, endpoints, infrastructure, and external connections.
PQC Remediation Workflow: Drives step-by-step remediation through runbooks, ticketing integrations, safe change control, and validated closure.
Continuous Cryptographic Posture Management: Keeps inventories current, detects drift, and supports long-term crypto-agility as threats and standards change.
Executive Program Management: Gives CISOs real-time status, clear next steps, phased milestones, and reporting tied to business outcomes.
IBM Quantum Safe Explorer is a quantum readiness assessment tool that helps enterprises locate and understand cryptographic assets across their environments.

A successful quantum readiness assessment should lead to a practical program with measurable risk reduction. Enterprises should avoid treating PQC as an isolated research project owned only by the cryptography team. The transition will affect business leadership, security, cloud infrastructure, application development, network engineering, PKI teams, procurement, vendors, and compliance functions.
Define the business risk model. Identify high-value assets, sensitive data sets, customer-facing applications, revenue-critical services, regulated systems, and data that must remain confidential over long time horizons. This top-down view ensures that technical discovery focuses on what is most important to the business.
Create a bottom-up cryptographic inventory. Assess code repositories, TLS and SSH endpoints, cloud services, certificates, VPNs, APIs, data stores, endpoints, network devices, and third-party applications. The goal is to establish a Cryptographic Bill of Materials that includes algorithms, key sizes, certificate chains, protocols, ownership, dependencies, and deployment locations.
Prioritize remediation based on more than algorithm type. A system using RSA may be technically exposed, but it should not automatically be remediated before a more critical service that protects long-lived customer data or supports a regulated transaction. Prioritization should account for business value, confidentiality lifetime, harvest-now, decrypt-later exposure, exploitability, dependency complexity, and relevant regulatory deadlines.
Establish a recurring governance model. Assign accountable owners, create milestones by business unit or application, route remediation work through existing ticketing systems, and validate closure before marking findings complete.
Everything you need to know about this news
A quantum readiness assessment identifies where an organization uses cryptography that could be affected by quantum computing and evaluates the associated risk. PQC remediation is the work of actually fixing those exposures: selecting replacement algorithms, updating applications and infrastructure, testing compatibility, managing vendor dependencies, and validating that the changes are complete.
The strongest enterprise platforms connect these stages. They do not stop at inventory or visibility; they help teams prioritize the highest-risk cryptography, assign work to the right owners, track progress, and maintain a current cryptographic posture over time.
A cryptographic inventory tells security teams where algorithms, certificates, keys, and protocols exist. It does not necessarily identify which findings create the greatest business risk, which teams own the affected systems, or what remediation sequence will minimize disruption.
Enterprises need to connect inventory data with business context. This includes identifying high-value assets, confidentiality requirements, regulatory context, service dependencies, and potential business impact. That connection helps CISOs justify investment and gives technical teams a clear plan for what to fix next.
Harvest-now, decrypt-later risk refers to the possibility that attackers can collect encrypted information today and retain it until quantum computing capabilities make the encryption easier to break. This matters most for information with a long confidentiality lifetime, such as financial records, healthcare data, intellectual property, government information, and long-term customer identity data.
A quantum readiness program should identify data that requires long-term protection and prioritize the cryptographic systems protecting that data. Waiting until quantum computers are broadly available may be too late for information that adversaries have already collected
Enterprises should prioritize post-quantum cryptography remediation by starting with business risk, then connecting it to the technical crypto inventory. The highest priority is typically given to cryptography protecting high-value assets, long-lived confidential data, customer-facing systems, regulated services, and critical infrastructure.
