Do you trust a brand's current reputation despite a publicized cyber breach from years ago?

Artificial intelligence platforms often prioritise past security failures when assessing brand trustworthiness, according to a recent study by Sefiani. The research analysed how AI search results integrate historical incident data, revealing a significant gap between broad category discovery and trust-related enquiries.

Why it matters

The findings highlight a major challenge for companies as AI tools increasingly rely on older editorial media coverage to fill informational gaps. When organisations fail to provide their own clear explanations of past breaches, AI models default to legacy reports, which can disproportionately impact consumer perception.

The study utilised 30 prompts per brand across ChatGPT, Google AI Mode, and Google AI Overviews to measure citation frequency. Corporate-owned content appeared in nearly 90% of total responses, while editorial media coverage was cited in approximately 60% of instances.

This organisation conducted the study using the Surfacd AI visibility platform to analyse search responses.

The details

While research shows that breach history appears in 42.2% of trust-related AI queries, this figure can climb as high as 59.1% for specific organisations. Consumer sentiment remains sensitive, with roughly one in 10 Australians having stopped buying from a company following a breach, prioritising preventive actions and transparency as key factors for continued loyalty.

The Tech Race

This development highlights a critical juncture in the evolution of AI search, as models increasingly replace traditional index-based discovery with generative synthesis. The shift forces a rethink of how organisations manage their digital footprint to ensure that historical incidents do not dominate automated trust assessments.

Users relying on AI for research should be aware that search results may disproportionately emphasise past negative news rather than current security posture. When verifying brand trustworthiness, consumers should cross-reference AI summaries with direct company communications to get a balanced view of incident handling.

The takeaway

Organisations should proactively document their security improvements and preventive measures to ensure AI models have contemporary information to index. For consumers, the study serves as a reminder to look beyond top-level search summaries when evaluating a brand's reliability.
