Global Post-Quantum Cryptography (PQC) Consulting | Quantum Risk, Quantum Readiness & Cryptographic Governance | SITG-Consulting

Quantum Computing Will Change Cyber Security. Preparation Starts Today.

Every organisation relies on cryptography.

Banks rely on it to secure financial transactions.

Governments rely on it to protect national infrastructure.

Healthcare providers rely on it to safeguard patient records.

Manufacturers rely on it to secure operational technology.

Cloud providers rely on it to establish trust.

Every VPN, SSL certificate, digital signature, software update, encrypted database, authentication system, API and secure communication depends upon cryptography.

The challenge is that the cryptography protecting today's digital economy was never designed to withstand large-scale quantum computing.

That is why organisations around the world are beginning their transition towards Post-Quantum Cryptography (PQC).

SITG-Consulting helps organisations understand that transition before it becomes a crisis.

We provide independent consulting services focused on Post-Quantum Cryptography, Quantum Risk Management, Quantum Readiness Assessments, Cryptographic Discovery, Cryptographic Governance, Enterprise Risk Management, Cyber Resilience and Strategic Transformation.

Our approach is evidence-based, vendor independent and built around one principle.

You cannot secure what you cannot see.

Global Quantum Risk Consulting

Business no longer operates within national borders.

An organisation headquartered in London may host applications in Frankfurt, process payments in Singapore, manufacture products in Bangkok, store data in Sydney and serve customers in New York.

Quantum risk follows those dependencies.

SITG-Consulting provides international consulting services supporting organisations across global markets, including:

United Kingdom

London, Edinburgh, Glasgow, Birmingham, Manchester, Bristol, Leeds.

Europe

Paris, Berlin, Frankfurt, Munich, Brussels, Amsterdam, Rotterdam, Luxembourg, Zurich, Geneva, Vienna, Madrid, Barcelona, Lisbon, Rome, Milan, Dublin, Copenhagen, Stockholm, Oslo, Helsinki, Warsaw, Prague, Budapest, Bratislava, Bucharest, Sofia, Zagreb, Ljubljana, Athens, Moscow, Saint Petersburg and Kyiv.

Asia-Pacific

Bangkok, Singapore, Tokyo, Osaka, Seoul, Beijing, Shanghai, Shenzhen, Hong Kong, Taipei, Kuala Lumpur, Jakarta, Manila, Hanoi, Ho Chi Minh City, Phnom Penh, Vientiane, Yangon, New Delhi, Mumbai, Bengaluru, Hyderabad, Chennai, Sydney, Melbourne, Brisbane, Perth, Canberra, Auckland and Wellington.

Middle East

Latin America

Mexico City, Bogotá, Lima, Santiago, Buenos Aires, São Paulo, Rio de Janeiro and Brasília.

Africa

Johannesburg, Cape Town, Pretoria, Nairobi, Lagos, Accra and Casablanca.

Wherever organisations operate, they face the same challenge.

Understanding where cryptography exists.

Understanding who owns it.

Understanding the business risk.

Building a practical roadmap towards quantum readiness.

What Is Post-Quantum Cryptography?

Post-Quantum Cryptography (PQC) is the next generation of cryptographic algorithms designed to resist attacks from both classical and quantum computers.

Unlike today's widely deployed RSA and Elliptic Curve Cryptography (ECC), PQC algorithms are designed to remain secure even when cryptographically relevant quantum computers become available.

Migrating to PQC is not a software upgrade.

It is an enterprise-wide transformation programme affecting applications, infrastructure, cloud services, identity systems, hardware security modules, third-party suppliers, operational technology and business governance.

That is why successful organisations begin with discovery rather than deployment.

What Is Quantum Risk?

Quantum risk is the business risk created by dependence upon cryptographic algorithms that may become vulnerable to future quantum attacks.

This includes:

• Long-term confidential information.

• Digital identities.

• PKI infrastructure.

• Authentication systems.

• Digital signatures.

• Software signing.

• Secure communications.

• Customer information.

• Financial transactions.

• Government records.

• Intellectual property.

• Industrial control systems.

• Supply chain trust.

Quantum risk is not simply an IT issue.

It affects governance, compliance, procurement, operational resilience, mergers and acquisitions, cloud strategy, enterprise architecture and board-level decision making.

Quantum Readiness Starts with Visibility

One of the biggest mistakes organisations make is asking:

"When should we migrate?"

The first question should always be:

"What exactly are we migrating?"

Most organisations cannot answer with confidence:

• How many certificates exist?

• Which algorithms are deployed?

• Which applications depend upon RSA?

• Which suppliers still rely upon legacy cryptography?

• Which systems cannot currently support PQC?

• Which business services are most exposed?

Without those answers, migration planning becomes guesswork.

SITG-Consulting helps organisations replace assumptions with evidence.

Why Organisations Choose SITG-Consulting

We are independent.

We are vendor neutral.

We focus on evidence rather than marketing.

We help organisations understand their cryptographic estate before recommending solutions.

Our work focuses on governance, visibility and strategic decision making rather than simply deploying new technology.

Why Governance Matters

Replacing cryptographic algorithms is only part of the challenge.

Organisations also need:

Executive accountability.

Policy.

Standards.

Ownership.

Risk management.

Supplier governance.

Architecture.

Continuous monitoring.

Continuous assurance.

Independent validation.

Without governance, today's successful migration programme becomes tomorrow's unmanaged legacy environment.

The Business Case for Quantum Readiness

Preparing early allows organisations to:

• Reduce migration risk.

• Improve visibility.

• Meet emerging regulatory expectations.

• Reduce long-term implementation costs.

• Protect customer trust.

• Improve resilience.

• Reduce business disruption.

• Strengthen governance.

• Improve board reporting.

• Support strategic investment decisions.

Quantum readiness is not simply about preparing for future quantum computers.

It is about understanding today's cryptographic risks before they become tomorrow's operational failures.

Frequently Asked Questions

What is Post-Quantum Cryptography?

Post-Quantum Cryptography (PQC) is a new generation of cryptographic algorithms designed to remain secure against attacks from quantum computers.

What is a Quantum Readiness Assessment?

A Quantum Readiness Assessment evaluates how prepared an organisation is to transition towards Post-Quantum Cryptography by examining governance, cryptographic visibility, business dependencies and organisational maturity.

What is a Quantum Risk Assessment?

A Quantum Risk Assessment identifies where current cryptographic dependencies create future business, operational or regulatory risk.

What is Cryptographic Discovery?

Cryptographic Discovery identifies where cryptography exists throughout an organisation, including applications, infrastructure, cloud platforms, certificates, keys and trusted communications.

What is a Cryptographic Bill of Materials (CBOM)?

A CBOM is a structured inventory of cryptographic components and dependencies, providing organisations with the visibility required to plan and govern PQC migration effectively.

Which industries should prepare now?

Any organisation relying on encrypted information, digital identities, software signing, cloud infrastructure or critical systems should begin planning for Post-Quantum Cryptography.
