Empowering Everyone to Benefit from Secure Infrastructure.

Light Squares builds secure and simple systems that solve hard problems leveraging modern hardware and the latest research.

Trusting Software Supply Chains. Verifiably.

CHALLENGE

Secure software requires a trustworthy link between source code (that humans can audit) and binary artefacts (that are black boxes and difficult to inspect). However, this link is lost in modern CI/CD pipelines running on opaque infrastructures—leading to hard-to-reason about provenance and high ongoing maintenance costs. This gap has made the supply chain a primary target for attacks and a focus for new regulations like the EU Cyber Resilience Act (CRA) and NIS2.

SOLUTION

We believe in secure-by-default. Our solution moves build processes into isolated environments that use hardware-based trust anchors to guarantee integrity—removing the need to trust the underlying infrastructure. We integrate in existing CI/CD pipelines and produce certificates that allow all downstream consumers to instantly verify the provenance and integrity of every single software artefact.

Verifiable Provenance
Providing essential provenance for software artifacts for organizations with elevated security and compliance obligations.
Hardware-based Trust
Use hardware-backed security to guarantee build integrity without trusting the underlying infrastructure.
Compliance Ready
Meet the highest SLSA standards and prepare for EU CRA and NIS2 regulations.
Seamless CI/CD Integration
Integrate with existing workflows (e.g., GitHub Actions, GitLab) with minimal changes and benefit right away from strong, verifiable build guarantees.

Unlocking the Value of Your Data with Verifiable Trust.

CHALLENGE

Regulations and organisational processes often slow-down collaboration on sensitive data—making them expensive and stressful—while not providing enforced data security controls. These hurdles address an important need: proprietary data is the most valuable asset in the AI-first world, but only if you can use it. Too often, promising partnerships and new technologies are passed over simply because the complexity of sharing data is too high.

SOLUTION

Our solution provides easy-to-use, compliance-ready data clean rooms designed specifically for pilot projects and ad-hoc collaborations. By using hardware-backed security, we allow data owners to verify that their information remains confidential and secure throughout the entire process. By accelerating the initial phase of exploration, companies can identify the most-valuable collaborations sooner and innovative companies can prove value.

Accelerate Collaboration
Fast-track pilot projects and ad-hoc collaborations without the overhead of traditional data sharing agreements.
Verifiable Confidentiality
Data owners can verify that their information remains confidential and secure throughout the entire process.
Compliance Ready
Easy-to-use data clean rooms designed with regulatory compliance in mind from the start.
Hardware-backed Security
Leverage Confidential Computing to enforce data security controls at the hardware level—not just policy.

Empowering Everyone to Benefit from Next-Gen Security Technology.

CHALLENGE

Traditional security focuses on protecting data-at-rest and data-in-transit. However, this is not enough for the modern cyber threat landscape. Regulations, such as EU DORA, now require protecting data-in-use bringing insider threats into scope. Modern hardware features (Confidential Computing) provide the technology to achieve this without having to trust the infrastructure. However, building robust solutions is still challenging due to lack of integrated frameworks and standardized components.

SOLUTION

We provide robust building blocks (base images, attestation verification, and more) and resources to allow engineering teams to start quickly and confidently. This allows organisations to pilot in-house Confidential Computing use-cases while reducing ongoing maintenance costs such as tracking hardware developments, firmware updates, and CVEs.

About Light Squares

Daniel and Mario met at the University of Cambridge during their PhDs. Recognising that modern security technologies are underutilized due to their complexity, they founded Light Squares in September 2025 to bring their vision to life. As an independent, founder-owned company, we focus on building honest, effective tools that protect against modern threats—making next-generation security accessible.
