There is one talk that has ‘security’ in it’s title: ” Cloud Platforms and the Product Management Lifecycle: Cloud Costs, Data Analytics and Security”. I guess this is better than previous hardware startup events, which were 100% security-free. Still, there is not enough security content in these hardware startup events. 😦
