Arcjet Extends Runtime Policy Engine to Block Malicious Prompts - DevOps.com
"The Arcjet AI prompt injection protection capability is based on an LLM that the company has been specifically training to detect patterns indicative of risky prompts that can then be blocked using a runtime policy engine built using WebAssembly (Wasm)."
"The only way to discover these issues after an application has been deployed is to analyze logs, which by then means a DevSecOps team is already too late to prevent anything malicious from occurring."
"The Arcjet runtime policy engine now prevents those prompts from ever reaching the AI model in the first place while adding less than 100 milliseconds of overhead to an application."
Arcjet has developed a prompt injection protection capability that detects and blocks risky prompts before they are shared with large language models. This capability utilizes a specifically trained LLM and a runtime policy engine built with WebAssembly, making it easier to integrate into various application codes. The primary aim is to prevent malicious prompts that could compromise application environments or expose sensitive data. Initially focused on prompt-extraction and shell-injection protection, Arcjet plans to enhance its security measures over time.
