VulnOptiCON (formerly the Vuln4Cast TC) is a FIRST Technical Colloquium dedicated to exploring and sharing practical and creative ways to put vulnerability, configuration, or exploit data to work. Whether you are estimating, measuring, predicting, tracking, visualising or otherwise playing with vulnerability and exploit data, this may be the event for you. Our goal is to make the workshop as interactive as possible, so that as a community, we can inform and strengthen each other’s outcomes, adopt and adapt new ways of thinking, and uncover new opportunities.
A good vulnerability forecast doesn’t start with code or exploits; it starts with a simple question: how many problems will we have tomorrow, and are we truly prepared to face them? In cybersecurity, our greatest enemy isn't the bug—it's the uncertainty about how many more are waiting. Let’s get together to talk about real-world vulnerability-related problems, and work as a group on potential solutions.
We offer several session formats, so even if you only have the beginnings of an idea, it is worth exploring how it might fit. This is a great environment for both new speakers (we’re a small-ish, friendly group), and seasoned speakers looking for feedback (we’re highly engaged and want to get involved). You do not need to be a data visualisation guru or Dr DataScience to get involved – though they are always welcome, and have built the foundation for this conference.
Oh also, you have to be living under a cyber rock to have missed the recent hoopla around #ProjectGlasswing and #Mythos. This is not the end of the story. The AI landscape is vast and evolving and our challenge to you is to tell or show us something about #AI and #securityvulnerabilities that we haven’t already seen or heard…
Sponsorship gives your organization different avenues to reach both experienced and up-and-coming vulnerability management and cybersecurity data science professionals. A motivated community of interest makes a good event, but sponsorship makes the event great. Sponsorship helps defray various event costs including the venue, food and beverage, keynote, and travel. Perhaps more importantly, sponsorship supports new people and new thinking by covering ticket costs for a number of students.
