Amazon Bedrock AgentCore Browser now reduces CAPTCHAs with Web Bot Auth (Preview)
Amazon Bedrock AgentCore Browser provides a fast, secure, cloud-based browser for AI agents to interact with websites at scale. It now enables agents to establish trusted, accountable access quickly and reduce CAPTCHA interruptions in automated workflows through Web Bot Auth, a draft IETF protocol that cryptographically identifies AI agents to websites. Traditional security measures like CAPTCHAs, rate limits, and blocks often halt automated workflows because Web Application Firewalls (WAFs) treat all automated traffic as suspicious - meaning AI agents frequently need human intervention to complete their tasks.
By enabling Web Bot Auth, AgentCore Browser streamlines bot verification across major security providers including Akamai Technologies, Cloudflare, and HUMAN Security. It automatically generates security credentials, signs HTTP requests with private keys, and registers verified identities - getting you started immediately without the need to register with multiple WAF providers or manage verification infrastructure.
Web Bot Auth support for AgentCore Browser is available in preview in all nine AWS Regions: US East (N. Virginia), US East (Ohio), US West (Oregon), Asia Pacific (Mumbai), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Europe (Frankfurt), and Europe (Ireland).
