On our tenth anniversary, we returned to Kauai. Gisele and I had been there for our honeymoon, capturing glorious photos our whole trip.

- [State of Security Vendors: AtlSecCon 2026](https://www.duha.co/reports/state-of-security-vendors-atlseccon-2026/) - Large regional conferences force a very different format on exhibitors.
