Horizen Labs helps organizations find where quantum risk sits in their estate, decide what to fix first, and migrate to quantum-resistant cryptography without disrupting the systems they run today. Every engagement can start with the Quantum Threat Assessment, a human-led review delivered in 5 to 10 working days at a fixed fee.
Find your starting point
A quantum-resistant migration moves through four stages: govern, assess and plan, remediate, and sustain. Horizen Labs offers services at every stage, and each can be commissioned on its own. The Quantum Threat Assessment shows which stage your organization is in and which services you need next.
Select a stage to see its services
Give quantum risk an owner, a budget and a place on the board agenda.
Find the cryptography you have, where it’s weakest and what it will cost to move.
Migrate in waves, sequenced by dependency, with a rollback position and evidence at every gate.
This stage starts from a completed cryptographic inventory and an approved target design. We can produce both in stage 2, or work from yours.
Make the next algorithm change routine, and build the skills to run it without us.

Quantum Threat Assessment
The Quantum Threat Assessment is a human-led review of your cryptographic estate by a Horizen Labs cryptographer. In 5 to 10 working days, at a fixed fee, it shows where quantum risk sits, ranks what to fix first and produces a costed roadmap your leadership can fund.
The assessment stands on its own. It doesn’t recommend Horizen Labs products, and you’re under no obligation to work with us afterwards.

Where the risk sits, ranked, with quick wins you can act on straight away.
Next steps broken into modules, so leadership can fund one stage at a time.
A concise summary your board, auditors and regulators can read without translation.
A Horizen Labs executive briefing gives your leadership team a shared view of the quantum threat, the cost of waiting and a mandate to act. It is written in plain language, covers current regulatory deadlines and ends with five actions leadership can approve the same day.
Customized to your needs
Every Horizen Labs engagement starts with a joint scoping session and a fixed price. You commission only the services you need, effort scales with your organization’s size, jurisdictions and estate complexity, and work is delivered remotely or at your site. Findings are written for boards, auditors and regulators.
Fixed-price engagements are confirmed after a joint scoping session, so the price reflects your estate rather than a generic band.
Every service stands alone. Combine them into a program only when it makes sense for you.
Effort scales with organization size, jurisdictions and estate complexity.
Every service can be delivered remotely or at your site, whichever suits your team.
The Horizen Labs enterprise engagement model is a four-step, engineering-led method for moving an organization to quantum-resistant cryptography. It starts with the Quantum Threat Assessment, builds a verified cryptographic inventory, turns that inventory into prioritized analysis, and ends with phased implementation and knowledge transfer to your own teams.
Step 1
A human-led review of your architecture and documentation that highlights your most critical risk areas. A Horizen Labs cryptographer analyzes your current security posture, identifies high-value assets and determines your quantum exposure across enterprise infrastructure.
Step 2
Discovery tooling deployed on your premises catalogs the cryptography in your systems, and our cryptographers verify what it finds. The resulting Cryptographic Bill of Materials (CBOM) records every encryption protocol, certificate, key exchange mechanism and cryptographic library across your network, including legacy systems and shadow IT.
Step 3
We turn the raw technical data from the CBOM into a clear, actionable report with fewer false positives and specific countermeasures. The analysis ranks vulnerabilities by business impact, sets out migration roadmaps, and pairs executive briefings with detailed technical specifications for your engineering teams.
Step 4
Engineering work to replace legacy cryptography with quantum-resistant standards. We provide hands-on implementation support and phased rollouts that minimize operational disruption, align your systems with the NIST quantum-resistant standards (FIPS 203, 204 and 205), and transfer knowledge to your internal teams for long-term sustainability.
Why us
Horizen Labs is a cryptography company with 20+ cryptographic, AI and quantum security experts, including multiple PhDs, and production systems in operation since 2019. Its quantum security work is human-led: cryptographers review each estate and apply judgment to every finding, rather than handing over automated scanner output.
Resources
Horizen Labs quantum security resources explain what quantum risk is, what it means for enterprise encryption and what to do about it. They are written in plain language for leaders, risk owners and security teams who need to understand the threat before they set a budget or plan a migration.

Harvest now, decrypt later (HNDL) is when adversaries copy encrypted data today and store it until quantum computers can break the encryption protecting it. Any data that must stay confidential for years is therefore exposed now, even though the quantum computer that could read it doesn’t exist yet.
Moving an enterprise’s cryptography takes years, and data intercepted today is already at risk. The National Institute of Standards and Technology (NIST) published its first quantum-resistant standards, FIPS 203, 204 and 205, in August 2024. Yet ISACA’s 2025 Quantum Computing Pulse Poll of 2,685 professionals found only 5% of organizations have a defined quantum computing strategy.
The Quantum Threat Assessment is a human-led review by Horizen Labs that shows where your cryptographic exposure sits, what to fix first and what it will cost. It takes 5 to 10 working days at a fixed fee, and you receive a board-ready risk snapshot and a costed roadmap.
A scanner shows where cryptography is used. The Quantum Threat Assessment explains what that means for your business. A PhD cryptographer weighs each exposure against data sensitivity, system dependencies and the regulatory dates that apply to you, and a senior specialist reviews every finding.
No. Horizen Labs assessments never recommend Horizen Labs products. Recommendations follow your estate and your risk, and you’re under no obligation to work with us after the assessment.
Yes. Every service can be commissioned on its own, so you can start at the stage that fits. Remediation work starts from a completed cryptographic inventory and an approved target design, which we can produce or take from your existing work.
Every engagement has a fixed price agreed after a joint scoping session. The price reflects the size and complexity of your estate and the jurisdictions you operate in. Application and vendor work is quoted in bands of 10, 25 or 50.
Horizen Labs aligns work to the NIST quantum-resistant standards (FIPS 203, 204 and 205) and to the guidance that applies to you, such as the UK National Cyber Security Centre (NCSC), the Australian Signals Directorate (ASD) Information Security Manual, the EU Digital Operational Resilience Act (DORA) for financial services, and your sector regulators.
