Europe’s Multilingual Reality Exposes AI Security Gaps
As the world becomes increasingly dependent on artificial intelligence (AI) to perform a wide range of tasks, from chatbots to software development, a concerning reality has emerged: not all languages are treated equally when it comes to AI model function and safety. This disparity puts European organizations at a heightened risk of security breaches, particularly those that operate across multiple languages.
The modern large language model (LLM) ecosystem relies heavily on natural language processing, which can be exploited by attackers through prompt injection attacks that manipulate text-based inputs. While leading models like OpenAI’s GPT and Google’s Gemini can process dozens to hundreds of languages, their performance and safety capabilities vary dramatically between languages. English, for instance, is the most supported language, benefiting from disproportionate training data and more efficient tokenization schemes.
However, this bias towards English poses a significant security risk. Many AI models perform logic, reasoning, coding, and math tasks best when prompted in English, and major AI labs often conduct safety tuning using English-speaking annotators. This creates an English-centric landscape that can be exploited by attackers who manipulate language inputs to bypass security measures.
The issue is not limited to comprehension or AI function problems; it’s a full-fledged security concern. As AI security vendor DeepKeep pointed out in a recent blog post, the AI security layer and guardrails that exist on top of many AI products don’t necessarily protect against jailbreaking and unsafe actions equally in every single language. This is particularly problematic when organizations collaborate and use AI tools across multiple languages.
Europe provides a unique example of this challenge. With 24 official languages recognized by the European Union, and numerous regional and minority languages spoken, it’s estimated that dozens of languages are used daily within one regulatory and economic bloc. Cross-border operations are common, making Europe more exposed to language gaps in daily operations.
According to Yossi Altevet, chief technology officer and co-founder at DeepKeep, the density of languages in Europe means that organizations here carry a heightened risk of hitting a language gap in their AI-powered systems. “Every multilingual enterprise, anywhere, carries the same underlying risk the moment it processes a non-English prompt,” he warns.
The implications are far-reaching, affecting not just European organizations but also those operating globally who rely on AI tools to process text-based inputs in multiple languages. As AI adoption continues to grow, it’s essential for security professionals and developers to acknowledge this language gap and take steps to address it.
In practical terms, this means that organizations should prioritize multilingual support in their AI-powered systems, invest in language-specific testing and validation, and implement robust security measures to detect and prevent prompt injection attacks. By doing so, they can mitigate the risks associated with language gaps and ensure a more secure AI landscape for all.
