Who are we?

443, Greenhat Consulting and Castelain have merged to create Australia’s leading Security, Network Management, PKI and Identity Management company. Our new name is Redcore.

Our combined success stories and strengths include:

• delivery of world-class IT security systems, services and design expertise to the majority of the country’s largest banks, financial institutions and government organisations.
• management of business critical networks and infrastructure for a wide range of clients.
• deployment and support of some of the nation’s largest and most successful Identity Management solutions.
• design and delivery of AUSkey, one of the nation’s largest authentication system deployments.

Our clients include blue chip corporates, particularly within the banking and retail sectors, as well as large government agencies.

Why we've merged

443, Castelain and Greenhat have been long term collaborators. We recognised in each other the same pragmatism and professionalism, and fierce integrity. We’ve long acknowledged each other’s capability, and understood well how each other worked.

So it seemed only natural to pull the teams together and pool our strengths.

We now have a truly national company with offices in Melbourne, Sydney and Canberra. We have insight into what a large spread of corporates and government agencies are doing to secure their systems and manage their users.

In addition to offering the same independent analysis and advice that our customers have always valued, we can now draw upon our strong partnerships with identity management, infrastructure management and authentication system vendors.
