Radware Launches “LLM Firewall” to Secure Enterprise Generative AI Use

On November 18, 2025, Radware Ltd. (NASDAQ: RDWR), a global leader in cybersecurity and application‑delivery solutions, announced the introduction of its new LLM Firewall, a novel add‑on for its Cloud Application Protection Services. The LLM Firewall is designed to act as a protective layer specifically for large‑language‑model (LLM) integrations within enterprise applications. According to Radware, it intercepts and blocks malicious prompts, jail‑break attempts, prompt‑injection attacks and resource‑abuse risks before they reach the underlying LLM model. Because the solution is “model‑agnostic” and easy to integrate, it works across different platforms and workflows without impeding innovation. Radware positions it as akin to a web application firewall (WAF) but for natural‑language prompt vulnerabilities: “Think of it as WAF for LLMs … but instead of guarding against HTTP‑level exploits, it helps mitigate natural language exploits specific to LLM behavior, and enhances protection for LLM models and integration, in real time.” A key highlight is that the product aims to stop exfiltration of personally identifiable information (PII) before it reaches the LLM, helping enterprises comply with global data‑protection frameworks such as General Data Protection Regulation (GDPR) and Health Insurance Portability and Accountability Act (HIPAA). Radware also states the product is built to address the “2025 OWASP Top 10 Risks and Mitigations for LLMs and Gen AI Apps.” In its corporate background, Radware emphasises that its AI‑driven cloud application, infrastructure and API security solutions support enterprises and carriers worldwide in defending against DDoS attacks, web and application threats, API abuse and bad‑bots. The announcement underscores growing enterprise concern around deploying generative‑AI capabilities safely, and Radware’s move signals a shift in the cybersecurity market toward specialized defenses tuned for LLM‑driven application use. #GenerativeAI #Cybersecurity #LLMFirewall #EnterpriseAI #SlimScan #GrowthStocks #CANSLIM
