Since the introduction of Security Enhanced Linux (SELinux) into the open source community in 2001, Owl has pioneered its use as the preferred mechanism to enable data transfer between security domains. From fundamental security architecture design and implementation, our expertise has expanded to include filter development, complete system development, system evaluation, certification testing, and accreditation process support. We have successfully executed technology transfers from Government programs to commercial products. We are experts in full lifecycle design, development, test, evaluation, certification, deployment, and accreditation of CDSs.
