Post-Quantum & Emerging Risk Readiness
Fortura’s Post-Quantum & Emerging Risk Readiness service helps organisations understand long-term technology risks that could undermine today’s security controls, and prepare for change before it becomes urgent.
Quantum computing refers to a new class of computing that can solve certain problems far faster than today’s systems. While large-scale quantum computers are not yet widely available, their development has direct implications for how data is protected today.
Many encryption methods currently used to secure data, systems, and communications are based on mathematical problems that quantum computers are expected to solve more efficiently in the future. This creates a risk for organisations that rely on long-term confidentiality, trust relationships, and cryptographic controls.
For most organisations, the risk is not immediate failure, it’s delayed exposure. Data protected today may be harvested now and decrypted later. Systems designed without future transition in mind may face costly, rushed remediation.
Post-quantum readiness is about understanding where assumptions may break and preparing for change before it becomes urgent.
Understand exposure to future cryptographic and technology shifts, including harvest-now-decrypt-later risk for long-lived secrets and data. Give technology and risk committees a horizon view that separates urgent transitions from watchful monitoring with clear triggers.
Identify systems and data with long-term confidentiality requirements where algorithm agility and key rotation matter most. Prioritise crown-jewel workloads and partner integrations so cryptography work tracks business criticality instead of vendor press releases alone.
Reduce the risk of sudden, forced security transformation by sequencing cryptography, identity, and architecture work to realistic budgets and change windows. Tie milestones to measurable crypto agility so teams fund the right foundations before forklift upgrades become unavoidable.
Support long-term security and technology planning with inventory of sensitive data, algorithm dependencies, and vendor commitments tied to horizon risk. Align engineering, procurement, and risk on upgrade paths that survive mergers, cloud moves, and evolving national guidance.
Build organisational awareness without unnecessary alarm by grounding messages in scenarios, timelines, and decision points boards can act on. Replace fear-based headlines with practical next steps so security budgets stay credible and engineering partners stay engaged.
Join us for results-driven collaboration and growth.
Managing sensitive or long-lived data requires clarity on cryptographic exposure, future technology shifts, and measured readiness planning without triggering unnecessary change.
We inventory cryptographic use across applications, infrastructure, and vendors: protocols, libraries, keys, and HSM usage. The register highlights long-lived keys and data that could be harvested now for later decryption.

This report examines the cyber resilience priorities shaping 2026, drawing on current threat intelligence, official cyber reporting, and Fortura's advisory experience.
Geopolitical cyber risk is no longer confined to governments and defence agencies. Global conflict, nation-state activity, hacktivism, and supply chain disruption can change the cyber risk environment for private organisations across every sector.
Explore why CTEM is becoming essential for organisations seeking a more proactive and risk-informed security posture.
AWS, Azure, and Google Cloud are not secure by default. Understanding the shared responsibility model, where cloud security gaps commonly appear, and what a cloud security posture assessment should cover is essential for any organisation running workloads in the cloud.
How employees using unapproved GenAI tools are exposing sensitive data, creating governance blind spots, and making shadow AI one of the most pressing cyber risk priorities for security and business leaders.
Machine identity security is critical as service accounts, API keys, cloud workloads, DevOps pipelines, and AI agents multiply cyber security exposure across environments. Explore practical strategies to reduce machine identity risk and protect your infrastructure.
The MITRE ATT&CK Framework is one of the most powerful tools in a security team's arsenal — but only if you know how to use it.
Master cyber risk reporting to board with practical strategies for clear, relevant, and actionable narratives that drive informed decision-making.
