How Baidu’s Large‑Model Security Guard Won Vivo’s Top Security Partner Award

Recently, the 2025 Vivo Developer Conference concluded in Shenzhen, and during the Security and Privacy track, Vivo presented the Best Security Technology Partner award to Baidu Security for its large‑model security guard, marking the third consecutive year of recognition.

The award highlights Baidu Security’s advanced technology in protecting edge‑deployed large models, addressing challenges such as reverse‑engineering of model parameters, limited device compute and defense capabilities, vulnerability to adversarial attacks after compression, and residual sensitive data in memory.

Baidu’s large‑model security guard provides a full‑stack, multi‑layered defense from cloud to edge, offering:

Comprehensive content security : Dual control from input to output, including multi‑turn dialogue rewriting, reference resolution, a high‑precision “red‑line knowledge base”, and a safety‑tuned large model for accurate responses and proactive guidance, with multimodal review matching or surpassing traditional expert models.

Edge‑specific solutions : Lightweight offline security operators that conserve compute while meeting regulatory offline review requirements, supporting log upload, dynamic policy updates, one‑click shutdown, and AI feature disabling.

Sharp attack detection : Semantic malicious intent identification and role‑play pattern detection to defend against prompt injection and other advanced attacks.

In addition to robust firewalls, Baidu Security offers a scientific, efficient security evaluation system with high‑quality datasets and an automated judging model that generates precise assessment reports, helping partners evaluate risks before model deployment and continuously improve security strategies.

Looking ahead, Baidu Security will continue collaborating with industry partners to drive healthy development of large‑model security, investing in reliable AI security services that support sustainable AI industry growth and a trustworthy AI application environment.
