Can You Trust Your AI? In mission-critical environments, trust isn’t optional, it’s foundational. By Light builds AI you can trust. Our solutions are engineered from the ground up with defense-grade trustworthiness at their core because reliability, accountability, and ethical alignment are non-negotiable in national security operations. Our AI systems are: • Transparent – offering insight into how decisions are made • Auditable – ensuring outputs can be traced, validated, and improved • Secure – hardened across the full lifecycle, from development to deployment • Ethically Aligned - designed to reduce bias, respect human oversight, and prioritize warfighter safety and decision dominance We align with DoD Responsible AI principles, embed rigorous validation and red-teaming processes, and ensure model explainability to support confident, informed decisions by both operators and commanders. The By Light AI Trust Model is more than powerful. It’s principled.

By Light Technologies at DSET 2025 A great 1st day at DSET 2025 in Bristol, UK! Plenty of interest in our space, cyber, and modeling and simulation offer in the UK. What we have to offer suits the Day 1 themes on the digital future and how NATO prepares for what lies ahead. A world that is in rapid transformation: geo-political, technological, and in complexity. There was an excellent keynote from Lt Gen Ralph Wooddisse, Commander, NATO ARRC, UK on how the ARRC trains to sense, decide, and fire. To top off the day we had the 1* Head of Defence Modelling and Simulation Office, Bijal Mistry, visit our stand to talk all things synthetic and cyber. We are looking forward to Day 2 and the 10th Anniversary awards dinner in the evening under the Concorde.
