Axiom Space

About

Axiom Space is building the world's first commercial space station while serving as the principal provider of commercial human spaceflight services to the International Space Station. The company completed the first private mission to the ISS in 2022, and its team has been involved with every ISS mission since the program's inception. The threat model here is existential: space systems operate in an environment where network segmentation means physical isolation, where a compromised control system can't be patched by rolling a truck, and where the attack surface includes everything from ground station telemetry to onboard life support interfaces.

The technical stack runs deep into embedded territory - C, C++, and Rust for flight software, LabVIEW and NI cRIO for hardware integration, FPGA programming for real-time control, and industrial protocols like Modbus RTU/TCP and RS-485/RS-232 for sensor and actuator communication. These aren't enterprise SaaS concerns; this is safety-critical infrastructure where timing constraints are measured in milliseconds and failure modes include loss of mission or worse. Security engineering at this level means understanding how to harden real-time operating systems, validate cryptographic implementations in radiation environments, and design resilient command-and-control architectures that can survive both Byzantine faults and adversarial inputs.

Axiom's work spans low-Earth orbit operations, astronaut training, space medicine, and microgravity applications for governments, researchers, and manufacturers. The company is designing space infrastructure to make commercial LEO operations viable at scale - a domain where cybersecurity intersects with aerospace engineering, signal integrity, and operational resilience in ways that don't map cleanly to terrestrial playbooks. This is systems work in the literal sense: architecting trust boundaries across hybrid ground/space networks, protecting telemetry streams from spoofing or injection attacks, and ensuring that safety-critical code paths remain deterministic under all conditions.

Axiado

Axiado is redefining the very foundation of platform security in an era where software-based defenses are proving insufficient against sophisticated ransomware, supply chain attacks, and physical side-channel exploits. The company exists to secure the world's digital infrastructure from the silicon up, addressing a critical gap where traditional cybersecurity solutions fail to detect threats that can remain hidden for hundreds of days. By embedding artificial intelligence directly into hardware, Axiado's Trusted Control/Compute Unit (TCU) provides the preemptive, real-time threat detection that modern cloud data centers, 5G networks, and accelerated computing platforms desperately need. The company's hardware-anchored approach integrates multiple critical security functions - including Root of Trust, Baseboard Management Controller, Trusted Platform Module, Hardware Security Module, and firewall capabilities - into a single system-on-chip protected by AI-driven threat detection. This innovative architecture doesn't just detect attacks; it stops them in real-time while also optimizing data center efficiency through dynamic thermal management that can reduce energy consumption by up to 50%. Backed by over $100 million in funding and recognized by Fast Company as one of the world's most innovative companies, Axiado is partnering with industry leaders like Jabil and Gigabyte to make AI-driven platform security the default standard for the digital infrastructure powering our world.

Amentum

Amentum is a global engineering and technology services contractor operating at the intersection of national security infrastructure and complex technical operations. Founded in 2020 but claiming a 117-year legacy through predecessor organizations, the company deploys approximately 40,000 professionals worldwide to support government and commercial clients across nuclear operations, environmental remediation, intelligence community programs, and defense infrastructure. The threat model here is operational: keeping critical facilities running, managing nuclear materials safely, and supporting intelligence operations that require both security clearances and deep technical capability. The technical domains span full-lifecycle facility programs - design through decommissioning - with particular concentration in nuclear energy operations, environmental management at contaminated sites, and systems engineering for classified programs. This means engineers and technical specialists work on everything from reactor operations to intelligence community support infrastructure, often in environments where both physical security and cyber controls are non-negotiable. Program management expertise centers on complex, long-duration government contracts where regulatory compliance and operational discipline define success metrics. Amentum's client base is predominantly the U.S. government and allied nations, positioning the company as a federal contractor rather than a commercial product vendor. The work involves supporting strategic operations where mission failure has national security implications - nuclear facility management, environmental cleanup of legacy defense sites, and technical services for intelligence agencies. For security practitioners, this translates to roles embedded in critical infrastructure protection, classified program support, and operational technology environments where the security perimeter extends to physical facilities, not just networks.

Axos Bank

We're a digital bank that's been around since before online banking was cool - we launched on July 4, 2000, as one of the first fully digital banks in the country. Our founders chose Independence Day for a reason: they wanted to break free from the traditional banking model with its expensive branches and hidden fees. Today, we've grown to over $20 billion in assets while staying true to our digital roots. We're headquartered in San Diego, but we serve customers nationwide without the burden of a costly branch network weighing us down. What we actually do is pretty straightforward: we offer checking, savings, mortgages, auto loans, and business banking through our website and mobile app. Our team builds the technology that makes banking work online - we're not just putting a mobile interface on an old bank system. We're publicly traded on the New York Stock Exchange (AX), FDIC insured, and we've been profitable for years because we don't have to pay for hundreds of physical locations. That means we can offer better rates and fewer fees to our customers.
