21SoftWare advances TSEL satellite security solution amid successful funding round

21SoftWare has announced it will advance its TSEL satellite security platform amid a successful initial funding round aimed at accelerating the Linux™-based operating system’s market readiness to tackle growing cyber threats to ground and space systems.


A spin-off from TriSept Corporation, a 30-year leading mission management services provider, 21SoftWare is laser-focused on enabling safe, secure, and reliable space operations. 21SoftWare’s first endeavor is the advancement of the TSEL (The Security Enhanced Layer) operating system, three years in development to meet the rising demand across the satellite and space industry for an affordable, easily deployable cybersecurity solution.


Deeply experienced in the space industry, the 21SoftWare team saw the growing need to harden satellite infrastructure and began development of the TSEL OS. To implement a zero-trust approach, TSEL is built on secure configurations that rely on powerful security tools, and leverage custom capabilities tailored to individual mission requirements.  


TSEL has successfully completed a series of stringent testing and development milestone achievements in preparation for flight. 21SoftWare provides a singular focus on the final stages of TSEL market readiness, which has attracted significant seed funding amid a capital drive to finalize preparations leading up to a variety of space missions slated to run TSEL satellite security as early as next year.


“21SoftWare is all about having top talent fully dedicated to getting TSEL through the final market readiness milestones to begin protecting missions in space as early as next year,” explained Rob Spicer, CEO and Founder of 21SoftWare. “We are in the midst of a highly successful seed funding round that will be integral to our commercial TSEL launch in space in the months ahead.”


Benchmark Space Systems, the premier space mobility solutions integrator, has selected 21SoftWare’s proven TSEL satellite security platform to protect upcoming multiple development platforms running its breakthrough MAAVRIC (Modular Adaptive Avionics for Rapid Integration and Configuration) universal control electronics and SmartAIM™ advanced onboard propulsion control software.


“Benchmark Space Systems is dedicated to extending our strategic partnerships and technical capabilities in ways that enable our customers and partners to leverage tailored mobility solutions to realize the full potential of their missions in space,” noted Chris Carella, Chief Commercial Officer for Benchmark Space Systems. “We’re working with 21SoftWare to understand where we can offer an integrated secured solution for a variety of platforms set to power missions ranging from orbital insertions to orbital debris removal operations.”


With an average of more than 2,600 small satellites launched each year and 25,000 satellites launched into orbit, every mission is at risk of a cyber threat. There are an estimated 3.8 million cyber-attacks per day, with the average cost associated with a corporate breach at $4.35 million. 21SoftWare and TSEL are focused on countering the growing cybersecurity threats to space and critical asset-based networks.
