New Agent Secures AI-Generated Code Across Popular Development Environments Materially Reducing Risk and Cost

Checkmarx, the leader in agentic AI-powered application security, today announced the general availability of its Checkmarx One Developer Assist agent, with extensions for top AI-native Integrated Development Environments (IDE) including Windsurf by Cognition, Cursor, and GitHub Copilot.

Checkmarx One Developer Assist is an advanced security agent that delivers real-time context-aware prevention, remediation, and guidance to developers from the IDE. Part of the Checkmarx One platform, this innovation enables modern engineering teams to identify, suggest, and remediate AI-generated code from the start, accelerating development without compromising security.

“With AI now generating a majority of new code in enterprise environments, traditional security approaches can't keep pace and will be overwhelmed,” said Jonathan Rende, chief product officer at Checkmarx. “We are focused on ensuring protection starts at the source—whether generated by humans or AI—by putting more power into developers' hands to identify and remediate issues in real-time.”

The initial Checkmarx One Developer Assist plugins are built for popular AI-native coding tools Windsurf, Cursor, and GitHub Copilot. As extensions to the Checkmarx One platform, they provide developers seamless access to autonomous, real-time prevention and instant remediation through their primary development environment.

During early access of Developer Assist, enterprise customers across healthcare, financial services, and consumer products reported easier access to accurate and complete threat alerts with faster remediation.

“We are very excited about the feedback from customers who have early access to Checkmarx One Developer Assist,” said Ori Bendet, vice president of product management at Checkmarx. “Developers report faster detection and improved insights. Our goal is to deliver a security-savvy teammate built into their workflow and to reduce the toil of manual processes.”

As AI accelerates code generation, it also amplifies security risks that manual reviews can't catch at scale. Developer Assist automates the entire security lifecycle—detection, analysis, and remediation—matching the speed of AI code creation.

Developer Assist is the first in Checkmarx's AI agent portfolio, with Policy Assist and Insights Assist agents launching later this year to serve AppSec teams and CISOs respectively.
