What's real about the dangers of the internet — and what's marketing theater
"If hackers can supposedly break in anywhere, anytime, easy as pie, then why is there still money in my account? Why does the economy work when everything could be shut down at any moment? Something doesn't add up. The truth is less spectacular: fear is a business model. Christoph Holz separates real danger from marketing theater — from total surveillance, which technically doesn't even work, to the mundane risk that actually counts: the human, the weak password, the update that was never installed. A calm, optimistic look at cybersecurity. Because whoever separates theater from danger acts effectively instead of in a panic. Whoever understands how, wins."
Anytime, anywhere, evil hackers can break in—supposedly. So why does anything still work at all, if everything is so vulnerable? Something doesn't add up here.
Evil hackers can break in anywhere at any time — supposedly. Just how dangerous it really is, anyone can check for themselves on their own bank account. Why is there still money available there? It should have been stolen long ago. Why does anything work at all if everything is so vulnerable?
Digital mass surveillance is an unsolvable problem of computer science. At best, you can catch stupid terrorists with it. That only raises the IQ of the remaining population. Even though the relevant US programs have failed, our belief in surveillance helps us behave. The legend of mass surveillance is a disciplinary measure.
Through vivid metaphors and examples, your guests grasp what technology can do — and where its limits lie.
You separate real danger from marketing theater.
You lead on security topics with confidence rather than fear.
They invest where it truly protects.

Voices from hosts and audiences.
Over the past weeks and months, we've worked with Christoph in a wide variety of formats (live, digital, hybrid). The talks themselves are maximally inspiring; beyond that, we got to know a highly professional, dedicated and in every respect fascinating person. It's a great privilege for anyone to be able to work with Christoph. We'll meet again, and we're really looking forward to it.
