TrustDefender™ (Symbiotic Technologies Pty Ltd) is an Australian owned and operated privately held company founded and headquartered in Sydney NSW. The company was established in December 2005 after over two years research and development into the global issue of growing online fraud in the online community, with a focus on ‘hardening’ the security at the PC and the growing number of mobile computing devices or technologies entering the market.

TrustDefender has worked closely with the financial services sector including leading Banks locally and internationally. Research & development was based on identifying the weaknesses in the overall security chain between Business to Consumer (B2C), Business to Business (B2B), Government to Consumer (G2C) and Government to Business (G2B) - where online criminals can penetrate the integrity of the user’s confidential information before and during an online transaction.

TrustDefender™ has developed a world first security solution that can be applied as an Enterprise Server solution or utilised independently by consumers using their home PC or mobile computing device. TrustDefender™ authenticates the security health status of the end user computer whilst extending beyond the security of the Enterprise environment.

TrustDefender™ was set up with a global focus in provisioning ‘On-Demand Endpoint Security’ and “Transaction Security” Solutions for Banks, Financial Institutions, Government, Online Businesses and for Consumers in general.

TrustDefender is a member of the "UN Global Compact" adhering to corporate social responsibility guidelines. (See Social Responsibility)
