Quantum Security · Why us

Your partner for quantum readiness

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.

The company

What sets us apart

  1. 01

    Applied cryptographic expertise

    Zero-knowledge, quantum-resistant and adjacent systems applied across enterprise and blockchain infrastructure.

  2. 02

    Human-led, not tool-led

    20+ cryptographic, AI and quantum security experts, with multiple PhDs on staff. Expert architectural reviews with context and judgment, not automated scanner output.

  3. 03

    Production-proven since 2019

    Large-scale product launches, live migrations and verifiable privacy platforms where security and uptime are non-negotiable.

  4. 04

    Full-stack delivery

    Encryption, protocol design and production engineering, delivered by one team from first assessment to systems running in production.

Tools find. People decide.

Discovery tools are essential. They are not a migration plan.

Automated discovery tells you which algorithms and certificates it can see. Deciding which exposure matters, in what order to fix it and how to explain it to your board takes cryptographic judgement. We work alongside the tools you already use, or help you choose the right ones.

Quantum resistance expertise

Led by an expert team, backed by applied cryptography research

Research depth

  • PhD-level expertise in the quantum security of cryptographic primitives, from foundational research at TU Darmstadt’s Cryptoplexity group.
  • Published quantum security research at CRYPTO, EUROCRYPT and PQCrypto, spanning quantum encryption models, indistinguishability proofs and quantum-resistant public key encryption.

Policy and standards

  • Contributed to working groups at NIST’s National Cybersecurity Center of Excellence (NCCoE) on migration to quantum-resistant cryptography (2023 to 2024).
  • Government-level threat assessment: advised the Swiss State Secretariat for Economic Affairs (SECO) on dual-use quantum computing controls under the Wassenaar Arrangement.
  • Member, World Economic Forum Quantum Economy Network and Global Future Council (2020 to 2024).

Enterprise track record

  • Built and delivered quantum threat programs for enterprise and government clients at Kudelski Security, an independent cybersecurity firm, over six years at Principal level.
  • Engaged banking, government and defence clients on cryptographic and quantum risk at IBM Research Zurich.

Field standing

  • Program Committee member at PQCrypto (2018 to 2026), the main international conference on quantum-resistant cryptography.
  • Peer reviewer for 40+ conferences and journals, including CRYPTO, EUROCRYPT, ASIACRYPT and FOCS.
  • Invited speaker at Black Hat Europe on real-world quantum security implementation failures.

Applied output

  • US patent awarded for a quantum-resistant secret code verification protocol.
  • Work package lead on the EU Horizon 2020 FutureTPM project, designing quantum-resistant trusted platform modules.

Questions buyers ask us

Straight answers

See the full FAQ →

Why not just run a discovery tool?

You should, and many good ones are on our ecosystem map. A tool shows the cryptography it can see. It cannot tell you which systems hold data that must stay confidential for decades, which dependencies will block migration, or what your board needs to hear. That judgement is what we provide.

Do you sell or resell quantum security products?

No. Our assessments do not cross-sell Horizen Labs products, and our recommendations are based on your requirements. When tooling is needed, we explain which category fits and why.

Who actually does the work?

Cryptographers and engineers from our quantum security team, led by Tommaso Gagliardoni. Every finding is reviewed by a senior cryptographer before it reaches you.

Do we have to commit beyond the assessment?

No. The Quantum Threat Assessment is fixed-fee with no obligation to proceed. If you continue, migration work is staged so you commission one module at a time.

How quickly can we start?

The assessment itself takes 5 to 10 working days. A free consultation is the first step, and it is with a cryptographer, not a sales script.
