Halcyon Bet Your Security Stack Will Fail. Its Payoff Is a $1 Billion Ransomware Safety Net
Most security vendors promise to keep attackers out. Halcyon starts with the impolite assumption that every layer - including its own - can fail, then sells enterprises a second chance before ransomware turns downtime into leverage.
Straiker
Straiker is a Sunnyvale-based agentic AI security company that helps enterprises deploy AI agents without handing attackers the keys. Its platform spans three jobs - Discover AI maps the agents, MCP servers, and workflows running across a company; Ascend AI red-teams them before deployment to surface prompt injection, goal hijacking, and tool misuse; and Defend AI blocks identity abuse, memory poisoning, and data exfiltration at runtime. Founded by former Palo Alto Networks and Akamai security leaders, Straiker raised a $64M Series A in June 2026, bringing total funding to $85M.
