The partnership combines NeXasure’s AI-driven threat defense and advisory services with Atsign’s identity-first secure communications platform, NoPorts, and secure-by-design application workflow.
San Jose, CA — September 2, 2026 — NeXasure, a pioneering provider of AI-driven cybersecurity managed detection and response solutions with advisory services, and Atsign, the innovative creator of a privacy-by-design networking platform, today announced the completion of bilateral marketing and reseller agreements that will help organizations reduce exposed infrastructure, strengthen cyber resilience, and secure both new and existing connected systems.
The partnership brings together two complementary technology philosophies:
NeXasure Defend leverages Frostbow from SKADI Cyber Defense, a synthetic and agentic AI solution deployed to detect, analyze, and respond to threats in real time. Atsign eliminates entire classes of attack vectors, by ensuring that no data is exposed without explicit permission, removing the reliance on open ports, static IP addresses, and vulnerable network configurations. Together, the combined solution portfolio offers organizations a comprehensive, privacy-first cybersecurity posture — from access to network architecture to active threat-mitigation, end-to-end.
“This is a significant step forward in our mission to deliver holistic, AI-powered cybersecurity solutions,” said Rick McElroy, Chief Executive Officer of NeXasure. “Atsign solutions eliminate the foundational vulnerabilities that attackers routinely exploit — open ports, exposed services, and discoverable infrastructure. Combined with NeXasure Defend’s real-time AI threat intelligence and our Advisory Services team, we are giving our clients an unprecedented level of protection that is both proactive and architecturally sound.”
Aparna Rayasam, CEO of Atsign, said: “Security needs to be built from day one, especially because AI accelerates how quickly applications, agents, and workflows are created. Atsign helps organizations build and connect systems with verified identity, end-to-end encryption, and with no exposed inbound infrastructure. NeXasure’s AI-driven defense and advisory expertise complements our approach by helping customers monitor, respond, and strengthen their overall security posture.”
NeXasure Advisory Services will provide clients with the strategic guidance needed to evaluate, implement, and optimize the combined technology stack, ensuring businesses ranging from small to large enterprises and government organizations can achieve maximum security efficacy.
