Cloudflare Introduces Firewall for AI to Safeguard Language Models

Cloudflare has recently announced the development of Firewall for AI, a cutting-edge protection layer designed to be deployed in front of large language models (LLMs) to proactively identify and prevent potential abuses before they reach the models.

Advanced Protection for Language Models

Unveiled on March 4, Firewall for AI is positioned as an advanced web application firewall (WAF) tailored for applications utilizing LLMs. This innovative toolset can be integrated in front of applications to detect vulnerabilities and offer insights into the threats facing these models.

Cloudflare’s Firewall for AI is set to merge traditional WAF capabilities like rate limiting and sensitive data detection with a novel protection layer that scrutinizes prompts submitted by users to spot any attempts at exploiting the model. By running on the Cloudflare network, this firewall enables early attack identification, safeguarding users and models from potential threats and abuses.

Addressing New Threats in the LLM World

While traditional web and API applications face vulnerabilities such as injections and data exfiltration, the realm of LLMs introduces a fresh set of threats due to their unique operational mechanisms. For instance, Cloudflare highlighted a recent discovery where researchers identified a vulnerability in an AI collaboration platform, allowing unauthorized actions to be carried out.

Cloudflare’s Firewall for AI will function akin to a traditional WAF, scanning every API request containing an LLM prompt for potential attack patterns and signatures. It can be seamlessly deployed in front of models hosted on Cloudflare’s Workers AI platform or any third-party infrastructure, and can be used alongside Cloudflare AI Gateway.

Enhanced Security Measures

The Firewall for AI will conduct a series of detections to pinpoint prompt injection attempts and other abuses, ensuring that the prompt aligns with the boundaries defined by the model owner. Additionally, it will scrutinize prompts embedded in HTTP requests and allow customers to create rules based on the prompt’s location within the JSON body of the request.

Once activated, Firewall for AI will meticulously analyze each prompt, assigning a score based on the likelihood of it being malicious, thereby fortifying the security posture of language models against potential threats.
