Apiiro Debuts Guardian Agent for AI Application Security

This week, Apiiro unveiled Guardian Agent, a new AI-powered application security (AppSec) tool designed to stop vulnerable and non-compliant code before it is ever written by AI models.

Guardian Agent promises to address gaps in traditional security scanning tools

The New York-based security vendor positions Guardian Agent as a response to the growing risk introduced by AI-native software development, where speed gains are often accompanied by significantly expanded attack surfaces and compliance challenges. 

According to Apiiro, traditional AppSec scanning tools are ill-equipped for this shift, generating excessive noise, false positives, and disconnected findings that security teams struggle to operationalize.

“The biggest challenge in AppSec today is not detection; it’s that enterprises cannot secure what they don’t understand. To stay in control and reduce risk, organizations must implement modern AppSec programs capable of executing 24/7 at scale,” said Idan Plotnik, CEO of Apiiro. 

“With the launch of Guardian Agent, we are positioning Apiiro at the forefront of the next era of AppSec—where understanding, prevention, and automation replace alert fatigue and reactive workflows,” Plotnik continued.

Guardian Agent is designed to operate continuously across the software development lifecycle (SDLC), applying architectural, runtime, and policy context in real time to proactively prevent risk rather than react after code is generated.

Securing AI-native development at scale

Apiiro argues that AI-assisted development has increased application risk by as much as tenfold, while overwhelming security teams with alerts they lack the context to prioritize. 

Guardian Agent aims to address this gap by acting as what the company describes as an “always-on AppSec engineer,” embedded directly into AI-driven development workflows.

The agent continuously analyzes software architecture, runtime exposure, organizational policies, and regulatory requirements. Using that context, it guards AI coding assistants and agentic development workflows without interrupting developer productivity or requiring additional security training.

A core capability of Guardian Agent is its ability to prevent insecure code generation at the prompt level. The tool can rewrite prompts in real time, generating secure, contextualized prompts for AI models using patent-pending technology. 

These prompts dynamically adapt as applications evolve, ensuring security guidance remains aligned with changing architectures and compliance needs.

From detection to prevention: Apiiro’s ongoing focus on AppSec

Guardian Agent is powered by Apiiro’s Deep Code Analysis technology, which relies on continuously updated Software and Risk Graphs. 

This data fabric enables organizations to holistically assess application risk and eliminate insecure design and coding decisions before they reach production.

Beyond prompt-level protection, Guardian Agent also automates threat modeling for feature requests and design documentation, reducing manual security backlogs that struggle to keep pace with AI-driven development cycles. 

The platform translates complex AppSec decisions into a shared language that developers, security teams, and executive stakeholders can all act on.

The launch represents an evolution of Apiiro’s existing AutoFix Agent, expanding its capabilities with the company’s Secure Prompt technology.
