Event summary

Agentic browser traffic surged 4.7x in September, from 12.5 million to 58.2 million requests.
Meta’s Muse, launched on September 22, accounted for 33% of September’s agentic browser volume in just 9 days.
AI agent traffic grew 41.5% QoQ, with DataDome’s network processing nearly 25 billion requests in Q3 2026.
Meta’s share of AI agent traffic slipped to 49.7% from 51.5% in Q2 as non-Meta agents grew faster (+47% vs. +36.5%).
8.9% of Muse’s requests targeted high-risk endpoints like forms, login, payment, and cart systems.

The big picture

The rapid rise of agentic browsers, particularly Meta’s Muse, signals a shift toward cloud-hosted AI agents that operate independently of user devices. This trend raises cybersecurity concerns as these agents increasingly interact with high-risk customer journey endpoints. The diversification of the AI agent landscape, with non-Meta agents growing faster than Meta’s, suggests a competitive market where trust management solutions will be critical for businesses to maintain security and operational integrity.
