Establishing secure connection…
Coral Stone
Coral Stone Holdings LTD was founded in Melbourne with a simple premise: security should be measured in outcomes, not paperwork. Today we operate as a global cyber security and enterprise software partner, combining round-the-clock monitoring with hands-on engineering to keep complex organizations resilient.
From our Australian headquarters and European office in Bolzano, our teams design, build, and defend the systems that banks, hospitals, and governments depend on — bringing together offensive security, cloud architecture, compliance, and custom software delivery under one roof.
Growth has never come at the cost of the fundamentals: verified detection, documented process, and engineers who show their work.
Coral Stone Holdings opens as a two-person penetration testing consultancy serving Victorian mid-market firms.
Round-the-clock monitoring goes live, anchoring what becomes our Managed Security division.
Expansion into the EU brings GDPR advisory and regional incident response under one banner.
Enterprise software, ERP, and cloud application teams merge with security to deliver secure-by-design builds.
Formal certification across information security management and payment card environments.
Today Coral Stone Holdings supports enterprise clients across six continents from two global hubs.
Every engagement is measured against a single question: did the organization's actual risk go down? Here's how we make sure it does.
OSCP, CISSP, and CEH-certified analysts lead every engagement, not junior staff learning on your environment.
Our SOC acknowledges critical alerts in under 15 minutes, 24 hours a day, 365 days a year.
Every finding is mapped to the frameworks your auditors actually check — ISO 27001, PCI DSS, HIPAA, GDPR.
Security and software engineering under one contract, so nothing gets lost in a vendor handoff.
From the first vulnerability scan to the last line of production code, our specialists carry deep, verifiable expertise in each domain.

Coral Stone's SOC team caught a lateral movement attempt at 2am and had it contained before our own staff were awake. That's the entire value proposition in one sentence.

The ERP platform they built has run without a single security incident for two years, across twelve production facilities.
Every plan includes a named account lead and audit-ready reporting. Custom scopes available on request.
For growing teams that need continuous coverage without a dedicated SOC.
Our most-deployed plan for mid-to-large organizations.
