HelpBench: Assessing the Ability of LLMs to Provide Privacy, Safety, and Security Advice

People increasingly turn to large language models (LLMs) for advice on numerous aspects of their lives. This paper investigates LLM capabilities in responding to questions about digital privacy, safety, and security, such as regaining access to a lost or suspended account, removing malware from a device, dealing with scammers or technology-facilitated abuse, and more. We curated a benchmark of 450 questions representing authentic user situations and developed rubrics for each question to evaluate factual accuracy and tone-based qualities of a response. We then developed and applied an auto-rater to evaluate responses from 18 state-of-the-art LLMs. Our results indicate that while models provide high-quality advice (with scores of 82\% on average), all models have significant room to improve, especially when tailoring advice to complex or high-risk scenarios.
