Marcus Thornfield
Senior Fraud Investigation Specialist
Marcus spent 15 years with Commonwealth Bank's fraud prevention division before joining us in 2023. He's particularly skilled at identifying complex invoice fraud schemes and has helped recover over .8 million for our clients. Marcus still gets excited when he spots a pattern others miss – it's like solving puzzles, but with real consequences for real businesses.
Dr. Penelope Ashworth
Digital Security & Risk Assessment Lead
Penny transitioned from academic research in cybersecurity to practical fraud prevention after seeing how theory translates to real-world protection. Her PhD in Digital Forensics from UNSW helps her stay ahead of emerging threats. She's known for explaining complex security concepts in ways that make sense to business owners who just want to protect their companies.
Isabella Montenegro
Client Relations & Education Coordinator
Isabella joined us after managing risk education programs for small businesses at ASIC. She understands that preventing fraud isn't just about technology – it's about helping people recognize red flags and building confidence in their decision-making. Her background in adult education helps her create training programs that actually stick with busy business owners.
Built on Trust and Results
We started caliviosara because we saw too many Australian businesses getting hurt by increasingly sophisticated fraud schemes.
What frustrates us most is when business owners blame themselves after falling victim to fraud. These aren't failures of judgment – they're the result of criminals who spend all day perfecting their deception techniques. Our job is to level the playing field by sharing what we've learned from investigating thousands of cases.
We're not interested in selling fear or complicated solutions that gather dust on shelves. Instead, we focus on practical education and straightforward protection strategies that fit into how real businesses actually operate. Every recommendation we make comes from seeing what works in practice, not what sounds good in theory.
