About Wardn

Australia’s leading data loss prevention and data protection experts.


About Wardn

Wardn is an information security firm based in Australia, and the only consultancy and managed service provider in the region that specialises in Data Loss Prevention (DLP) and Data Protection.

Our core team are security professionals with extensive experience securing some of the most complex environments in Australia, who have come together with the goal of helping clients understand their data protection and privacy obligations, and how complacency can impact their business and customers.

We strongly believe that data protection isn’t just about implementing technical controls and that real reduction of risk is also about leveraging technology to educate and inform employees how their treatment of sensitive and personal information can impact the business and its customers. This philosophy has been the basis of seeing our clients succeed where others have not, and drive the cultural change necessary to protect their information, and that of their customers and business partners.
