- [Launching the Duha One leadership newsletter](https://duha.co/2023/01/23/launching-the-duha-one-leadership-newsletter/): It's been a long journey as we've stood up Duha – writing and publishing 1% Leadership, launching our consulting services, and evaluating how to democratize leadership development. We fundamentally believe that leadership training is too often restricted to people who've already had long careers, rather than making it more available to everyone, everywhere. We're really
- [The Rainbow](https://duha.co/2021/04/12/the-rainbow/): Duha means "rainbow" in Slovak, and the story of capturing this picture illustrates a personal anecdote about leadership. On our tenth anniversary, we returned to Kauai. Gisele and I had been there for our honeymoon, capturing glorious photos our whole trip.

Despite its size at 3000 attendees and 173 exhibitors, CYBR.SEC.CON is still a regional conference. What does that mean? Exhibitors are
- [State of Security Vendors: Blackhat 2026](https://duha.co/reports/state-of-security-vendors-blackhat-2026/): State of Security Vendors-BH 2026.docxDownload Key Takeaways We have entered into an AI world. While nearly half of booths didn’t directly mention AI or agents in their taglines, the effects of AI are everywhere.

- [State of Security Vendors: Blackhat 2025](https://duha.co/reports/state-of-security-vendors-blackhat-2025/): The 359 observed Blackhat vendors, by and large, did a decent job of making their booths tell you enough of what they did so that you could self-select who to talk to, because there isn’t enough time to talk to every vendor. Almost 20% missed the mark: 16 vendors had no useful visible messaging and
- [AIpocalyptic Decisions](https://duha.co/keynotes/6-leadership-disciplines-copy/): Keynote: AIpocalyptic Decisions alternate title: The Impending AI/Complexity Apocalypse Humans are awesome at decision-making.

- [State of Security Vendors: AtlSecCon 2026](https://duha.co/reports/state-of-security-vendors-atlseccon-2026/): Large regional conferences force a very different format on exhibitors. Gone are the 40'x40' carnival spectacles and hundreds of competitors. Instead, 70 exhibitors are competing for the 1500-2000 pairs of eyeballs that will wander through (and they must, since lunch is right there). Rollups abound, but messaging is still a bit incoherent, with 20% of
- [State of Security Vendors: RSAC 2026](https://duha.co/reports/state-of-security-vendors-rsac-2026/): Of the 607 observed RSAC exhibitors, over 90% had visible, readable messaging that got you near to what the vendor did.
