In today’s digital landscape, cybersecurity platforms utilizing .Security domains are evolving alongside the rapid rise of agentic AI. A new wave of companies is emerging to secure autonomous systems, govern AI behavior, and manage the growing complexity of machine identities. This momentum is reflected in significant recent funding rounds, underscoring the urgency of building security infrastructure for the next generation of intelligent systems. XYZ Registry is committed to supporting innovators in the security space, and it is encouraging to see organizations adopting elite domain endings like .Security to establish their presence. Today, we’ll introduce you to three companies using .Security domains that are advancing agentic AI security across defense, identity, and governance: Jetstream.Security, Kai.Security, and Oasis.Security.
Jetstream.Security – Cloudflare customer – (United States)
Jetstream.Security is the online home of Jetstream, a cybersecurity platform focused on enabling enterprises to run AI systems with built-in governance, identity, accountability, and financial control. According to the company’s website, lack of oversight can introduce risk and slow adoption. As highlighted on the company’s website, Jetstream aims to replace uncertainty with trust by embedding governance directly into AI systems from the start. As reported by Fortune in March 2026, the company raised $34M in seed funding to advance its AI governance platform.1
According to the company’s website, Jetstream is building a “control plane for AI” that provides continuous visibility and governance across AI systems, including agents, models, tools, and workflows. The platform is designed to unify fragmented AI environments through discovery of AI assets, enforcement of identity and access controls, and monitoring of runtime behavior in real time. Key capabilities include agentic identity binding, design-time controls for structuring AI systems, runtime governance to detect drift and misuse, and financial accountability to track usage and cost. Jetstream.Security describes governance as a foundational layer for enterprise AI adoption.
Jetstream is led by co-founder and CEO Raj Rajamani, who previously served as Chief Product Officer at CrowdStrike and SentinelOne, where he contributed to building and scaling major cybersecurity platforms. The founding team also includes COO Jared Phipps, who held senior sales and go-to-market leadership roles at SentinelOne and other cybersecurity companies, CTO Jatheen (AJ) Anand, who has led engineering teams building large-scale AI and cloud platforms, and Chief Architect Venu Vissamsetty. Together, the team brings experience across cybersecurity, enterprise software, and AI infrastructure to Jetstream’s mission of enabling governed and accountable AI systems.

Kai.Security – GoDaddy customer – (United States)
Kai.Security is the online home of Kai, a cybersecurity platform founded in 2025 that is focused on redefining how security operations are executed in the age of AI. As shared on the company’s website, the platform is built on the premise that traditional, human-operated security tools are no longer sufficient to defend against machine-speed threats, and instead aims to replace fragmented security stacks with a unified, autonomous system. In March 2026, Kai emerged from stealth with $125M in funding.2
According to the company’s website, Kai is designed as a single agentic AI platform that performs end-to-end security functions across threat intelligence, exposure management, detection, and response. Rather than augmenting existing tools, the platform replaces siloed systems with a unified pipeline that continuously gathers context, assesses risk, prioritizes actions, and executes remediation. Kai emphasizes eliminating fragmented workflows and enabling security operations to move at machine speed, with customers reportedly compressing months of manual analysis into minutes. The platform is built to operate without human bottlenecks, positioning agentic AI as the core driver of modern cybersecurity operations.
Kai is co-founded by CEO Galina Antova and CTO Damiano Bolzoni. Galina is a co-founder of industrial cybersecurity company Claroty and serves on the boards of multiple cybersecurity organizations, bringing experience in building and scaling security platforms. Damiano previously co-founded SecurityMatters, which was acquired by ForeScout, and later led industrial and OT security initiatives at the company. His background also includes academic research in SCADA security and supervising doctoral work in the field. In April 2026, the company announced the appointment of Nick Degnan as Chief Revenue Officer, noting that he brings more than 20 years of experience in building and scaling high-growth revenue organizations across cybersecurity and enterprise technology, as Kai scales adoption of its platform. Together, their backgrounds span cybersecurity, infrastructure, and product development. You can learn more by following the company on LinkedIn @kai-security and visiting Kai.Security.
Oasis.Security – Name.com customer – (United States)
Oasis.Security is the online home of Oasis Security, a cybersecurity platform focused on managing and securing non-human identities (NHIs) across enterprise environments. According to the website, the shift to hybrid cloud, automation, and AI-driven systems has led to rapid growth in non-human identities such as service accounts, APIs, and bots, which now represent a significant portion of identity activity. As shared on the company’s website, Oasis is designed to secure and govern these identities throughout their lifecycle. In March 2026, Oasis Security raised $120M in Series B funding to expand its platform for non-human identity governance.3
According to Oasis.Security and their whitepaper on non-human identity management, Oasis provides a platform that combines discovery, posture analysis, threat detection, and automated remediation to manage non-human identities at scale. The platform is designed to provide visibility across hybrid and multi-cloud environments, assess risk posture, and enforce governance through policy-based automation. The website states that key capabilities include lifecycle management functions such as provisioning, ownership assignment, credential rotation, and decommissioning, designed to reduce operational complexity while improving compliance. As highlighted on the company’s website, Oasis uses an infrastructure-agnostic approach with broad integrations across cloud platforms and enterprise systems, providing centralized control over identities that are often created and managed in a decentralized manner.
Oasis Security is led by co-founder and CEO Danny Brickman. As shared on LinkedIn, Danny previously served as Head of Cyber R&D in the Israel Defense Forces, where he led cybersecurity research and development initiatives, and also held roles in product strategy before founding Oasis. His background includes experience in software engineering and participation in the Talpiot program, combining technical and leadership expertise. Together with the broader team, he brings experience in cybersecurity, engineering, and enterprise product development to Oasis’s mission of securing the rapidly expanding non-human identity landscape.

The adoption of .Security domains highlights how organizations in the cybersecurity sector are choosing industry-specific namespaces to strengthen their digital identity. Developed for the security industry, .Security provides a dedicated namespace aligned with this sector. The structure of the namespace allows organizations to choose domain names that precisely reflect their specific services, functions, or areas of focus. Unlike crowded domain extensions where the best names are taken, .Security domains are priced relative to their value, a deliberate approach that can deter bad actors and speculative registrations. The exclusive but unrestricted namespace further supports domain availability, top-tier status, trust, and legitimacy. Companies like Jetstream.Security, Kai.Security, and Oasis.Security demonstrate how emerging platforms can align their online presence with their core mission while making it easier for stakeholders to associate them directly with security-focused solutions. As cybersecurity evolves to address agentic AI, non-human identities, and real-time governance, .Security provides a clear and relevant foundation for companies building the next generation of security infrastructure. The domain underscores a direct connection to the industry, offering a memorable, purpose-aligned, and strategically smart choice for organizations shaping the future of digital defense.
