Beyond WAFs & API Security: Understanding the AI Security Gateway™ for AI
Learn why traditional security tools fall short for Generative AI and why a new, synthesized approach is essential to protect your LLM interactions.
The Unique Challenge: Why Traditional Security Isn't Enough for AI
Generative AI and Large Language Models (LLMs) communicate differently than traditional web applications. Interactions are conversational, data is often unstructured, and the risks involve manipulating model behavior or leaking sensitive information hidden within natural language – challenges that existing security categories weren't primarily designed to address.
Web Application Firewalls (WAFs)
Essential for blocking network-level attacks (SQLi, XSS, DDoS) on web servers, but they typically lack the deep content understanding and contextual awareness needed to analyze the nuances of LLM prompts and responses for threats like prompt injection or subtle data leakage.
API Security Gateways
Focus on securing the API structure – authentication, authorization, rate limiting, schema validation. While crucial, they often don't perform deep inspection of the payload content specific to AI risks (the meaning within the prompt or response).
Data Loss Prevention (DLP) Tools
Designed to find sensitive data patterns, but often operate asynchronously, aren't optimized for the real-time, low-latency demands of conversational AI, and struggle with identifying sensitive data embedded within unstructured, conversational text. They also don't address prompt-based attacks.
AI Point Solutions
Address specific issues like prompt injection but create a fragmented security posture. They often require application code integration, lack unified visibility, and don't cover the full spectrum of risks like data exfiltration in responses or broad content safety.
AI requires a security layer that is real-time, context-aware, content-intelligent, and unified.
Introducing the AI Security Gateway™: A New Security Architecture for AI
A AI Security Gateway™ is a new category of security solution engineered specifically for the unique demands of AI and LLM interactions. It acts as an intelligent, inline gateway that synthesizes multiple, specialized security functions into a single, cohesive defense layer operating directly on the AI traffic flow.
Key Characteristics of a AI Security Gateway™:
AI-Native
Designed from the ground up to understand LLM-specific vulnerabilities like prompt injection, jailbreaking, and the unique ways sensitive data can be exposed in conversational AI.
Inline & Real-Time
Sits transparently in the path between applications and LLMs (like a proxy), inspecting and enforcing policies on requests and responses as they happen, without requiring application code changes or adding significant latency.
Deep Content & Context Aware
Goes beyond simple pattern matching to analyze the meaning and intent within prompts and responses, identifying threats and sensitive data within unstructured, conversational text.
Multi-Layered Synthesis
Intelligently combines capabilities traditionally found in separate tools – data protection (PII, secrets), threat detection (prompt attacks), content safety (toxicity, filtering), and compliance logging – tailoring them specifically for AI interactions.
Adaptive & Dynamic
Designed to evolve alongside rapidly changing AI models, attack techniques, and data policies.
What Does a AI Security Gateway™ Do?
By synthesizing multiple security functions, a AI Security Gateway™ provides comprehensive protection for the entire AI interaction lifecycle:
Protects Sensitive Data
Detects and automatically acts upon (masks, redacts, blocks) PII, PHI, financial data, API keys, secrets, and custom-defined sensitive information within both user prompts and LLM responses.
Prevents Prompt-Based Attacks
Identifies and neutralizes various forms of prompt injection, jailbreaking attempts, and other instructions designed to manipulate or misuse the LLM.
Ensures Content Safety & Compliance
Filters inputs and outputs for toxicity, hate speech, banned topics, or other harmful content based on configurable policies. Helps enforce brand safety and responsible AI usage.
Enforces Custom Policies
Allows organizations to define specific rules regarding data handling, acceptable topics, or interaction patterns based on their unique requirements.
Provides Unified Visibility & Auditing
Offers a central point for logging, monitoring, and analyzing all secured AI traffic, simplifying governance and compliance reporting.
