ABOUT THE RANGE VILLAGE
​The Range Village is a community driven cyber range interest group aimed to provide community curated Cyber Range content for people who are interested in practicing their cyber skills such as active directory testing, lateral movements, defence evasion, and provisioning of an attack infrastructure. We live in a world where cybersecurity education is within a Google search or a GenAI prompt, but the access to a certain range or resource to practice those skills can be costly to individuals who are not in the position to self-fund a paid cyber range or premium access range.

ABSTRACT
Participants will expect open range(s) for them to participate in person. There will be one range, Hacker Jeopardy with mystery prize.

SET UP INSTRUCTIONS FOR PARTICIPANTS
Participants will need to bring their own laptop with a Kali Linux virtual machine

Career Trajectory AMA Series: Real Cybersecurity Career Moves, No Filters

Cybersecurity careers aren’t linear—and many of us reach a point where we start questioning our next move. End user to vendor, private to public sector, engineer to architect, practitioner to GRC—these transitions raise real concerns around skills, pay, identity, and long-term impact. This Career AMA series is built for people navigating those questions.

Every two months, we’ll host an open AMA with cybersecurity professionals who’ve actually made these shifts. No polished success stories or recruitment pitches—just honest conversations about what changed, what was harder than expected, what they got wrong, and what they’d do differently.

Expect candid insights, practical lessons, and space to ask the questions people usually avoid. If you’re considering a career move—or just want clarity on what’s possible in cyber—this series is for you.

AGENDA

• 6.30pm: Registration
• 7.00pm - 10.00pm: Career Trajectory AMA on Crossing the Aisle: Strategically Transitioning from End-User Roles to the Vendor Ecosystem
  Till Late: Networking
