Perplexity unveiled BrowseSafe a real-time HTML scanner tailored to catch malicious prompt-injection attacks embedded in webpages before an AI agent executes instructions.
Alongside this, it released BrowseSafe-Bench: an open benchmark suite simulating 14,700+ realistic attack scenarios to test defenses across diverse web environments.
The fine-tuned model (based on Qwen3-30B) reportedly delivers about 90–91% detection accuracy while maintaining the speed needed for smooth browser use. By offering this protection and open benchmarking, Perplexity is pushing the AI-browsing ecosystem toward greater security and transparency.
