a16z to Portfolio Companies: Cybersecurity Defense Advice for the Age of AI Agents

The a16z infrastructure team has issued cybersecurity advice to portfolio companies, warning that AI agents are being adopted at scale and each agent represents an internal threat. The team recommends doubling security budgets from approximately 10% of technology spending, implementing zero-tolerance policies for new features and product launches, shutting down idle labs, test environments, and zombie CI/CD projects, and expanding the number of agents rather than headcount to respond to threats at machine speed.
