What it sells: Checkmarx

What Checkmarx Developer Assist does[5]
Checkmarx Developer Assist provides real-time detection, remediation and actionable insights as developers write or refine AI-generated and existing code. It comprises two main elements, Realtime Scanning and Agentic-AI Remediation. Plugins exist for IDEs and for AI coding agents.
What Checkmarx MCP Server does[5]
The Checkmarx MCP Server defines the tools and APIs that allow AI agents to interact with Checkmarx cloud services from within the IDE. The MCP Service is installed automatically once the developer authenticates in the IDE.

What it sells: Phoenix Security

What Phoenix Purple does[1][2][5][7][8][9][14]
Phoenix Purple is an engineering-first application security platform. It connects directly to AI coding agents and delivers fixes as pull requests instead of tickets. Phoenix Purple runs deterministic SAST and SCA on a knowledge graph, adding reachability, a chainability map, and one-click assessment and remediation. Phoenix Purple is available in general availability.
What Phoenix Orange does[2][5]
Phoenix Orange answers what to fix and in what order. It aggregates every scanner into a single queue, strips out unreachable noise, attributes findings to the right team, and connects code-level findings to the cloud service where they run.
What Phoenix Green does[5]
Phoenix Green writes the fix as a pull request with the threat context already in the description. Risk tiering sets the path: safe changes move fast, moderate ones carry a review flag, and anything breaking or dangerous needs explicit human approval before it can merge.
What Purple Hook does[9]
Purple Hook is a local check that runs inside the AI coding assistant developers already use. It is generally available for Phoenix Purple customers.

About Checkmarx

Checkmarx sells Checkmarx Developer Assist, which delivers context-aware security guidance directly within a developer's IDE. Checkmarx Developer Assist helps prevent vulnerabilities before they reach the pipeline. As developers write or refine AI-generated and existing code, Checkmarx Developer Assist provides real-time detection, remediation and actionable insights.

Checkmarx Developer Assist comprises two main elements. The first is Realtime Scanning, which identifies vulnerabilities in realtime during IDE development of both human-generated and AI-generated code. Scanners run in the background whenever a developer edits a relevant file. Checkmarx scanners identify vulnerabilities and unmasked secrets in code. Checkmarx also identifies vulnerable or malicious container images and open source packages used in a project. Results are marked as Problems that are highlighted in the code and annotated with identifying icons.

The second element is Agentic-AI Remediation, in which a developer initiates an Agentic-AI session to receive remediation suggestions. Checkmarx feeds relevant information to the AI agent, which accesses the Model Context Protocol (MCP) server to gather data from proprietary databases and customized AI models. The AI assistant then uses this data to generate remediated code for the project. Developers can accept the suggested changes or chat with the AI agent to learn more about the vulnerability and fine-tune the remediation suggestion.

Checkmarx Developer Assist lets developers mark risks as Ignore, so that the risks are no longer shown in the IDE. A developer can Revive a risk at any time to resume showing that risk. Specialized realtime scanners identify vulnerable open source packages and container images, exposed secrets and IaC risks.

Checkmarx provides dedicated Developer Assist plugins for two types of coding platforms: IDEs (VS Code, Cursor, Kiro, Windsurf, Visual Studio and JetBrains) and AI Coding Agents such as Claude Code. In the coding agent plugin, Developer Assist steps in and remediates the risk as the assistant generates code. The plugin is currently available for Claude Code CLI, Copilot CLI and Cursor CLI.

The Checkmarx MCP Server is a secure gateway that bridges AI-powered development assistants with the Checkmarx security platform. The Checkmarx MCP Server defines the tools and APIs that allow AI agents such as GitHub Copilot, Cursor AI or Windsurf AI to interact with Checkmarx cloud services from within the IDE. Once the developer authenticates in the IDE, the MCP Service is automatically installed. The Checkmarx MCP Server authenticates the developer's IDE session with Checkmarx. The Checkmarx MCP Server exposes available Checkmarx tools and capabilities, such as code scanning, remediation and policy enforcement, as AI-accessible functions.

Checkmarx says the MCP standard lets any IDE-integrated AI assistant access Checkmarx engines and services, including SAST, SCA, IaC and API Security, through a unified interface. Checkmarx selected the MCP standard as the foundation for its agentic architecture. Checkmarx describes MCP as vendor-neutral and supported by a growing ecosystem of AI tools.

Developer Assist is available in three licensing models, each serving a distinct segment of Checkmarx customers.[1]
