AI Agents Grew 7,851% on the Internet Last Year
Automated traffic now vastly outpaces humans online — AI agent activity exploded 7,851% YoY in 2025, per HUMAN Security.
The internet is no longer mostly human. HUMAN Security's 2026 State of AI Traffic & Cyberthreat Benchmark Report — based on over one quadrillion digital interactions — confirms what many suspected: bots and AI systems now dominate web activity.
In 2025, AI-driven traffic surged 187% from January to December alone. Automated traffic grew 23.51% year-over-year, while human traffic crept up just 3.10% — meaning automation is scaling 8x faster than people. The starkest number: AI agent traffic up 7,851% YoY.
What changed isn't just volume — it's behavior. AI agents moved from passively crawling the web to actively transacting on it: browsing products, logging into accounts, completing checkouts. High-impact sectors hit hardest include retail, streaming, and travel. The security implication is real — a bot completing a checkout looks identical to a legitimate customer, until it doesn't.
Why it matters: the web's default assumption of a human on the other end is now officially broken — and security, ad tech, and product teams haven't fully caught up.
