ABOUT US
OUR TEAM
Klein & Co. was founded on the philosophy that a small team of experienced practitioners, with the right leadership, continual development and technical capabilities, could provide the best digital forensic services to clients across Australia and internationally.
All of our matters are led by Nick Klein, a recognised international expert, who prior to founding Klein & Co. was a senior member of the largest corporate forensic practice in Australia and previously a Team Leader in the High Tech Crime team of the Australian Federal Police, providing technical expertise to local and international police investigations and intelligence operations.
Members of our team have presented expert evidence in both civil and criminal matters in Australia and overseas, including Nick leading the computer forensic evidence for the AFP in the Bali bombing trials in Indonesia and providing expert testimony in Australia's first Commonwealth cybercrime prosecution.
As a Certified Instructor with the prestigious SANS Institute, Nick is one of a small group internationally and one of two Certified SANS DFIR Instructors in the Asia Pacific region. He is a regular presenter at industry events around the world, a member of Interpol's Global Cybercrime Expert Group and guest presenter at some of Australia's leading educational institutions.
Our team has been engaged as experts in hundreds of complex and sensitive cases including commercial litigation, electronic discovery, criminal proceedings, financial fraud, corruption, employee misconduct, theft of intellectual property. We have also led the response to some of Australia's most high profile breaches.
We pride ourselves on being active members of the international digital forensics community and believe that professional development is a daily requirement, supported through regular industry training and certification on the latest tools and techniques.
