Ready Never Waits

What comes next may be unknown, but it doesn’t have to be uncertain.​

By Light enables warfighters to thrive on ready. With reconfigurable collective trainers, crews or individual operators that can prepare for any scenario across multiple vehicles and weapons systems. Deployable on-site and built to be rapidly reconfigured, our Mission Reconfigurable™ trainers enable the warfighter to train when and where it matters most. With high-fidelity cyber ranges, we enable cyber operatives to prepare in realistic environments for real-world readiness. From the front lines to online, we empower our customers to prepare for what may come next and dominate what does come next. ​​

We create workforces that defend with ready, developing every employee to detect, defend, and defeat threats in a digital-first world. From a single student to an organization-wide approach, By Light develops a cyber workforce ready for a cyber-first world. We defend networks so you advance with ready. From the largest Zero Trust implementation in government to identity management in high-stakes, highly sensitive environments, to monitoring networks to find the next vulnerability before the next attack, move mission forward with security that’s ready to support every next step. ​

We allow operators to communicate with ready, designing communications technology to allow secure communication over multiple transports and disparate devices. From 5G to SATCOM to wired networks, we create solutions to enable information sharing at the speed of mission dominance.​

We work with ready, eliminating the long development, proprietary technology stovepipes and last-gen pace of play that slows projects down. With a singular focus on success, not SOWs, we create a continuously optimized process to eliminate gaps in performance in cyber security, modeling and simulation and communications. We create IT solutions and write software to help agencies stay ahead of the technology and optimize mission performance.​

At By Light, we prepare everyone to be ready for what comes next, no matter what comes next.​

By Light. Ready Never Waits.​
