Security teams don’t miss alerts because they’re careless, they miss them because their SIEM never stops yelling. This talk shows how poorly timed, constant, or context-free alerts become meaningless noise and how simple fixes like throttling, prioritization, and timing can turn a SIEM into a tool that actually gets noticed when it matters.

Most identity threat detection fires after the attacker has authenticated.
By then, you're not preventing anything, you're containing it.

The behavioral signals that precede an identity attack are detectable earlier. A password spray generates a distinct pattern across providers during the attempt phase, before a single login succeeds.

Sub-5-second detection. Complete investigations, not raw alerts.

API abuse = misuse of trust, not system compromise.
“Early-stage API attacks are often subtle and blend into normal operations.”
“Automation amplifies every attack. Bots can enumerate endpoints… faster than humans could.”
