Sunburst and the SEC: Five Years on the Front Line of a Nation-State Attack.
ISC2 LA Lunch & Learn
On Saturday, December 12, 2020, Tim Brown, then CISO of SolarWinds, got the call every security leader dreads: a nation-state actor had compromised the company's build system and shipped tainted code to up to 18,000 customers. SUNBURST became one of the most closely watched cyber incidents in history. Three years later, the SEC charged SolarWinds and Tim personally, the first time a CISO had ever been charged. The case was largely dismissed in 2024 and dropped entirely in December 2025.
In this candid session, Tim covers the first hours of the response, choosing transparency over the safe legal answer, rebuilding trust with customers, and what it was like to be named personally by a regulator. He'll be honest about what they did well, where they were lucky, and what every security leader, executive and board should do now so they are ready, not lucky.
