Xybern
Xybern has joined Blossom Capital's inaugural portfolio, marking an important milestone in the company's growth and its expanding presence in Saudi Arabia.
The inaugural portfolio brings together nine early-stage technology companies selected through DominAIte, Blossom Accelerator's AI-focused investment and commercialisation platform supported by Saudi Arabia's National Technology Development Program (NTDP).
Xybern joins the portfolio as an agentic cybersecurity company building the security and authorisation layer for autonomous AI in regulated and mission-critical environments.
Securing Autonomous AI Before It Acts
Artificial intelligence is rapidly evolving from systems that primarily generate information into autonomous agents capable of interacting with real-world systems and infrastructure.
AI agents can increasingly access enterprise systems, call APIs, interact with MCP servers and tools, process sensitive information, execute workflows and delegate tasks to other agents.
This introduces a fundamental security challenge:
An AI agent may be capable of performing an action, but that does not mean it should be authorised to perform it.
Xybern is building the security and authorisation infrastructure designed to address that distinction.
The Xybern Authorisation Layer sits between agent intent and execution, controlling autonomous actions before they reach the underlying system.
Every action passes through a mandatory authorisation pipeline designed to authenticate agent identity, resolve authority, evaluate applicable controls and determine whether the action should be allowed, denied or paused for human approval before execution.
Xybern provides controls across agent identity, authorisation, agent-to-agent delegation, MCP and tool security, human approval, external-agent federation, runtime containment and cryptographic provenance.
The principle is simple:
Autonomous capability should never imply autonomous authority.
Expanding Xybern's Presence in Saudi Arabia
Joining Blossom Capital's portfolio represents an important step in Xybern's growing presence in Saudi Arabia and the wider region.
As enterprises and governments deploy increasingly autonomous AI systems, security, authorisation, governance, sovereignty and accountability become critical requirements — particularly in regulated and mission-critical environments.
Xybern is building specifically for these environments.
The company has already expanded its technology for organisations operating across Saudi Arabia and the Gulf, including support for Arabic-language enterprise AI environments.
Through the Blossom ecosystem, Xybern will continue developing relationships across the region while advancing its security and authorisation infrastructure for organisations deploying autonomous AI.
Building the Security and Authorisation Layer for Autonomous AI
Dr. Charalambos Theodorou, Founder and CEO of Xybern, said:
"As AI systems become capable of taking increasingly consequential actions, organisations need more than authentication. They need infrastructure capable of determining whether an agent has the authority to perform a specific action before that action reaches execution."
He added:
"Joining Blossom's ecosystem is an important step for Xybern as we continue building the security and authorisation infrastructure required to control autonomous AI in regulated and mission-critical environments."
Xybern is building the security boundary between autonomous AI intent and real-world execution — controlling every agent, action, delegation and tool call before execution.
Your AI agents act. Xybern decides if they can.
About Xybern
Xybern is the security and authorisation layer for autonomous AI in regulated and mission-critical environments, controlling every agent, action, delegation and tool call before execution.
The Xybern platform provides organisations with infrastructure for agent identity, authorisation, delegation control, MCP and tool security, human approval, external-agent federation, runtime controls and cryptographic provenance.
Xybern is designed to enable organisations to deploy increasingly autonomous AI while maintaining control over who can act, what they can do, what they can access and under which authority, before execution occurs.
