In the realm of technology, AI is forging ahead at a blistering pace, offering the tantalizing promise of propelling humanity to unprecedented heights. Yet, within the transformative potential of artificial intelligence also lurks a spectrum of risks, a fact we dare not underestimate. While we firmly believe that the benefits of AI outweigh the potential pitfalls, it is imperative that we confront these risks head-on. By doing so, we not only secure the future of AI but also expedite its widespread adoption and continued advancement.


To address and mitigate these challenges, we proudly introduce Semantic Shield as an open-source initiative. At its core, Semantic Shield serves three fundamental purposes:

  1. Protecting AI Systems from Misbehaving Users

  2. Safeguarding Users from AI Misbehavior

  3. Address the risk of Data Leaks

In a more detailed breakdown, Semantic Shield encompasses the following functionalities:

  • Topic Moderation: Define and enforce restrictions on certain topics (e.g., politics) that should be avoided in AI interactions.

  • Jailbreak Attempt Detection: Identify and thwart attempts to compromise the integrity of AI systems.

  • Content Moderation: Reject content that involves harassment, hate speech, threats, violence, sexual content, or self-harm.

  • Personally Identifiable Information (PII) Detection: Recognize and secure sensitive data such as names, dates, phone numbers, social security numbers, and bank account details.

  • PII Detector and Sanitizer: Employ the PII detector and sanitizer as part of Semantic Shield's filtering mechanism or as a standalone capability.

  • Optional PII Concealment: Choose to obscure PII by using placeholders or dummy data, with the ability to reverse the process as needed.

  • Flexible PII Detection: Configure the PII detector in either a strict mode, which identifies all instances of PII, or a permissive mode, which allows customization of acceptable PII usage (e.g., permitting names when generating emails).


In essence, Semantic Shield emerges as a vital tool in ensuring responsible and secure AI interactions, simultaneously fostering the accelerated growth of AI technology.


Why Semantic Shield?

In the world of rapidly advancing language models like ChatGPT and Bard, the potential for enterprises is immense. However, to fully harness the power of these technologies, enterprises often find themselves needing to incorporate additional internal data, some of which can be highly confidential and sensitive. This heightened need for data security cannot be met by existing, conventional security solutions.

LLMs and Generative AI need to incorporate Private Data

As businesses evolve and embrace AI-powered strategies across various functions, such as Marketing, Sales, Support, and Business Services, security requirements naturally intensify. The proliferation of Personally Identifiable Information (PII) and Intellectual Property (IP) risks necessitates robust security measures.

In this context, it's essential to recognize that AI-enabled Marketing and Sales have the capacity to drive revenue growth while significantly reducing advertising waste. Furthermore, AI-optimized Business Services and Support functions enable companies to reinvent their products and services, leading to even greater cost savings.

Semantic Shield steps in as a critical solution, addressing the escalating security demands of this AI-powered era. By ensuring the protection of sensitive data and mitigating risks associated with PII and IP, Semantic Shield empowers businesses to embrace AI's potential with confidence.


Architecture & Approach


Current AI/LLM Security solutions offer limited protection due to their architecture and approach. The following three principles help address their limitations

  • A Network DMZ-Inspired Architecture

  • Shift Left approach to AI Security, Safety & Alignment

  • Leverage the existing security body of knowledge, processes and solutions


Current AI/LLM security solutions

A Network DMZ-Inspired Architecture


Semantic Shield's architecture is inspired by a network DMZ (Demilitarized Zone), emphasizing a fortified intermediate defence layer between AI systems and external entities. While it incorporates core DMZ principles, its primary focus is AI security, safety, and alignment.

Shifting AI Security, Safety & Alignment Left


Semantic Shield takes a proactive approach to AI Security, Safety, and Alignment, initiating these crucial aspects during the planning and architectural phases, well before the machine learning process begins. In contrast, existing solutions primarily focus on providing protection during the Inference stage.

Leveraging a Wealth of Knowledge


Drawing from a wealth of knowledge, Semantic Shield taps into proven methodologies and principles in Information and Network Security to fortify the system's robustness. This approach builds upon existing security frameworks, tailored to meet the unique demands of AI security, safety, and alignment.


Maximizing Synergy with Existing Security Solutions


Semantic Shield prioritizes synergy with existing security solutions, harmonizing our architecture with proven industry strategies. This ensures seamless integration into existing ecosystems, enhancing AI security effectiveness and simplifying implementation for organizations.


Unique Consideration for Language AI and Quantitative AI


Semantic Shield tailors security for both Language AI and Quantitative AI, ensuring comprehensive protection across the AI spectrum by recognizing and addressing their unique needs.


In summary, Semantic Shield blends security wisdom with innovation, creating a robust solution tailored to AI security, safety, and alignment needs.
