Founded in 2013 and headquartered in Toongabbie, New South Wales, Defencebyte is an Australian cybersecurity company offering antivirus software for Windows devices. Their antivirus solution includes real-time protection, behavior-based threat detection, automated scanning, and system rollback tools. The software is designed to run quietly in the background without slowing down performance, which is especially useful for users with legacy systems. Defencebyte offers multi-device coverage, flat-rate pricing, a 30-day free trial, and a 30-day money-back guarantee.
