Who We Are

Meet the team at ThreatDefence.

Our Story

ThreatDefence is an Australian company founded in 2014 in Sydney by a small group of security practitioners – security incident responders and threat hunters. From our hands-on experience, we learned that only very few businesses notice security events in their network, and even fewer can proactively action on them.

We observed organizations getting breached, with attackers living on their networks for months and sometimes years. We also seen cyber security investigations drag on for days and even weeks, as incident responders could not get use of their security event data, and struggled to manually correlate security events collected from endpoints, network systems and cloud service providers.

That’s how ThreatDefence was born. Our SecOps Platform was created to help companies of any size to deploy world-class Security Operations, and contain threats with deep visibility and structured evidence.

Our Customers

Our platform has been deployed globally, serving hundreds of customers across various industries, including service providers, healthcare, digital services, government, finance, legal, retail, and mining. In 2023, we continue to expand our reach and support more organizations worldwide.

Our Mission

Our mission is to provide every business with complete access to their security data, making security detection and response affordable and reducing the time it takes to implement security operations capabilities from months to minutes.

Our Team

Our core team is composed of highly skilled engineers, data scientists and engineers who work closely together. Our team members possess a wealth of experience in machine learning, threat detection and incident response.
