Read →HardenWall studies how AI can support Search and Rescue (SAR) work, and conducts independent cybersecurity research.
A research project exploring how AI can help Search and Rescue (SAR) teams narrow down where to look, faster — aimed at reducing preventable loss of life when every minute counts.
Research published here is not validated for operational or emergency use — predictions and findings are estimates for research purposes only.
Everything HardenWall works on falls under one of these.
Applying modern AI to real problems in Search and Rescue — where a faster, better-informed guess can matter.
Self-directed security research — vulnerability analysis, tooling experiments, and write-ups — done independently, not as paid client work.
HardenWall is run as an independent research effort, not a business. This work doesn't earn money and isn't done as paid client services. The motivation is simple: AI and security research is more useful when it's shared. Current and future projects here are published as working research — not polished into a pitch.
A short, hand-picked list — not necessarily the newest, the most representative.
