Quantum Grids

Quantum Grids is a Lithuanian cybersecurity startup focused on post-quantum readiness for critical infrastructure, public sector and regulated organisations.

As quantum computing advances, many of today’s widely used cryptographic algorithms will become vulnerable. Organisations that operate long-lifecycle systems, sensitive data, industrial environments, public services or regulated digital infrastructure need to understand their exposure early and prepare realistic migration paths.

Quantum Grids is developing a practical post-quantum readiness tool that helps organisations discover where cryptography is used, identify vulnerable protocols and systems, assess harvest-now-decrypt-later risk, and prioritise migration towards quantum-safe cryptography.

Our focus is on making the first step of post-quantum transition actionable: cryptographic visibility, risk-based prioritisation, clear recommendations and migration planning. We aim to support cybersecurity leaders, CISOs, IT teams, OT environments, public institutions and regulated companies that need to prepare for the post-quantum era without disrupting existing operations.

Quantum Grids combines expertise in cybersecurity, critical infrastructure, OT security, ISO 27001, NIS2, IEC 62443, cyber risk management and large-scale technology transformation.

We are currently looking for pilot partners, research collaborators, cybersecurity experts and investors interested in post-quantum security, critical infrastructure resilience and practical cybersecurity innovation.
