Developer Assist Keeps Your AI Code Secure

AI coding tools accelerate both output and risk. The Developer Assist agent seamlessly delivers real-time, inline fixes that keeps pace with AI-accelerated code.

Problem

AI Code is Vulnerable. LLMs can plan and execute attacks. LLMs can plan and execute attacks.

Security for AI code

AI Code is Vulnerable

Next-gen AppSec that works for devs

Security teams face machine-led and machine-speed threats that traditional tools cannot counter. Is your team ready?

Problem

Teams Ship Risky Gen-AI Code. Current AppSec Can’t Keep Up with AI-created vulnerabilities

Fix as fast as AI code

Teams Ship Risky Gen-AI Code

Outpace risks, keep DevOps pace

81% of orgs knowingly push vulnerable code to production, with nearly one-third of their software now AI-generated.

Problem

AI Code Increases Breach Risk. Ungoverned Gen-AI coding expands and accelerates vulnerabilities.

Cut MMTR, Avoid Breaches

AI Code Increases Breach Risk

Don’t become a stat, remediate early

SecureFlag data shows 98% of companies experienced at least one breach tied to insecure coding in the past year.

Commit As Fast As AI Codes

Bring real-time, autonomous risk detection and inline fix directly into your IDE. No platform required.

Instant Detection. Instant Remediation.

Most AI copilots surface issues but leave the hard work to you. Developer Assist generates validated remediations as you code, helping you resolve vulnerabilities before they reach the repository.

F01 IDE Integration

F02 – Real Time Detection

F04 – Safe Refactor

F03 – Contextual Fixes

F05 – Dual Mode Remediation

F01 IDE Integration

IDE Integration

Developer Assist runs natively in your preferred AI-powered IDE, delivering instant security insight without disrupting your flow. Everything happens locally in your editor, giving you responsive protection built for modern development speed.

F02 – Real Time Detection

Real-Time Detection

Identify risky logic as it’s written or generated across source code, dependencies, IaC files, and secrets. Inline detection shortens the cycle between introduction and fix, dramatically reducing mean time to remediation and preventing issues from stacking down the pipeline.

F04 – Safe Refactor

Safe Refactor

Safe Refactor applies security fixes across all impacted files and dependencies with controlled, predictable edits. It prevents build failures, avoids broken dependency chains, and keeps your project stable while you resolve issues at top speed.

F03 – Contextual Fixes

Contextual Fixes

Every recommendation is tailored to your specific code context. Developer Assist analyzes intent, structure, and usage patterns to propose secure alternatives that make sense for your application, so you understand what changed and why it’s safer.

F05 – Dual Mode Remediation

Dual Mode Remediation

Pre-Commit: Stops vulnerabilities before they ever enter your repository by applying secure changes inline as you code.

Post-Commit: Guides developers through clean, policy-aligned fixes for existing findings with the same safe, explainable remediation workflow.

FAQ

Does Developer Assist require the Checkmarx One platform?

No. Developer Assist works as a standalone agent that runs directly inside supported IDEs. It provides real-time detection and safe, AI-guided remediation without requiring any Checkmarx One license. It’s an easy entry point that can scale later if needed.

What data does Developer Assist send outside the IDE?

No source code leaves the IDE. Developer Assist only transmits minimal metadata like package names, versions, and container image identifiers to retrieve verified remediation guidance. All processing is ephemeral and aligned with SOC 2, ISO 27001, and GDPR.

How does Safe Refactor prevent broken builds?

Safe Refactor analyzes your codebase, identifies every location affected by a package upgrade or code change, and automatically applies consistent, validated updates. By updating all dependent references and patterns together, it eliminates the missed edge cases and partial fixes that commonly cause builds to break.

What kinds of vulnerabilities can Developer Assist detect?

The standalone agent detects issues across source code, dependencies, secrets, and IaC files. It surfaces risks in real time as developers type, with explainable guidance and instant fixes delivered directly in the IDE.

Can Developer Assist scale across multiple projects?

Yes. Although lightweight and developer focused, Developer Assist supports scanning multiple applications in real-time, right from the IDE.
