Cybersecurity company Horizon3 has launched its first APAC-based 'sovereign' instance, hosted out of Sydney.

The new Australian point of presence keeps all customer data resident in-country and enables Australian organisations to run continuous, production-safe autonomous penetration testing under full data sovereignty.

The instance is purpose-built for the likes of government agencies, critical infrastructure operators, Defence Industrial Base organisations, major banks, and other regulated entities.

By keeping data resident in Australia and operating under local control, it helps organisations meet key requirements under the SOCI Act, APRA CPS 234, the ASD Essential Eight, and related frameworks.

“Australian organisations face the same AI-accelerated threat landscape as the rest of the world, but they rightly demand that the tools they use to defend themselves meet the highest standards of data residency and national control,” said Gareth Cox, VP of sales, APJ at Horizon3.

“With the Sydney Sovereign Instance, customers can now run the World’s Best AI Hacker continuously and safely, knowing their data never leaves Australia. This enables them to move beyond assumptions and continuously prove which exposures actually matter—and that remediation works.”

The Sydney instance complements Horizon3’s existing points of presence in the United States and Germany.

It follows Horizon3’s recent US$250 million Series E at a valuation exceeding US$2 billion, which is funding accelerated international expansion, including deeper investment across Australia, New Zealand, and the wider Asia-Pacific region.

Horizon3’s NodeZero proactive security platform platform has already executed more than 310,000 production-safe autonomous security tests for more than 7,500 organisations worldwide, the company claimed, including multinational banks, major healthcare networks, four Fortune 10 enterprises, and national security agencies.
