Lenovo Targets Shadow AI with SentinelOne Tool for Singapore Firms

The deployment of Prompt Security addresses what Lenovo identifies as "shadow AI" use within organizations. This refers to employees utilizing AI tools without explicit company approval, a practice that survey data suggests is common among office workers in Australia, Japan, the UK, and the US, with 66% reporting such use despite believing it was prohibited.

A key function of the tool is to mitigate security risks associated with generative AI, specifically prompt injection attacks. These attacks involve embedding malicious instructions within user inputs to manipulate an AI model's behavior, posing a threat to data integrity and system security.

For Singapore's financial sector, these capabilities become particularly relevant. Regulators like the Personal Data Protection Commission (PDPC) have issued guidelines on personal data use with generative AI, while the MAS-backed MindForge consortium, which includes major banks, has listed prompt injection as a significant security concern for the industry.

Lenovo's move extends its existing partnership with SentinelOne, a cybersecurity firm that acquired Prompt Security in September 2025. This expansion reflects a broader industry concern, with Lenovo citing research indicating that 90% of IT leaders perceive gaps in their defenses against AI-driven threats.
