# **Secure Your F# Projects from Vulnerable Dependencies**

Build, manage, and secure your F# applications with confidence. Gain full visibility into the open source components used across your F# projects and reduce risk throughout the SDLC.

## Modern F# Development Requires Modern Dependency Management

The [F# language](https://fsharp.org/) is a functional-first, strongly typed programming language that runs on the .NET platform. Like other .NET-based ecosystems, F# projects rely heavily on third-party packages distributed through [NuGet](/content/products/language-support/nuget-and-c/index.html) and other repositories. Managing these dependencies across distributed teams, CI/CD pipelines, and evolving F# builds introduces risk — especially when open source components contain [security vulnerabilities](/content/resources/articles/what-are-open-source-vulnerabilities/index.html), license conflicts, or malicious code. Sonatype helps organizations gain control of their F# development environments by improving visibility, governance, and automation across the entire software supply chain.

## Supported Features

### Dependency Intelligence

Identify and evaluate open source components in your F# projects, including transitive dependencies from NuGet packages.

### Vulnerability Detection

Find and fix known vulnerabilities in your F# dependencies early in the development process, reducing risk before your code goes live.

### Automated Policy Enforcement

Set security and license policies to guide development teams toward safer components during the F# build process.

### License Compliance

Monitor open source licenses to ensure your F# applications meet legal and organizational requirements.

### Repository Management

Manage how F# packages enter your development environment by controlling access to internal and external repositories.

### CI/CD Integration

Embed security and quality checks into your F# build pipelines to stop risky components from moving downstream.

## Improve Software Supply Chain Security for F# Applications

From financial platforms to cloud services, F# is used in many high-value systems. To properly secure them, static code review isn't enough. You need to continuously monitor third-party components throughout the entire [software development lifecycle](/content/resources/articles/guide-to-software-development-life-cycle/index.html).

- #### Reduce Risk Early

Catch vulnerabilities and policy violations during development rather than after deployment, minimizing remediation costs.

- #### Increase Developer Confidence

Provide developers with clear guidance and automated guardrails, so they can move quickly without sacrificing security.

- #### Strengthen Governance

Establish consistent standards across teams and F# projects to maintain compliance and reduce operational risk.

## Frequently Asked Questions

### **Does F# depend on external packages?**

Yes. Most F# projects use third-party libraries distributed through NuGet and other repositories. These [dependencies](/content/resources/articles/what-are-software-dependencies/index.html) can introduce security and compliance risks if not properly managed.

### **How can I secure my F# build pipeline?**

Integrating automated dependency analysis, [vulnerability detection](/content/solutions/vulnerability-management-tools/index.html), and policy enforcement into your CI/CD workflow helps prevent insecure components from entering your F# build process.

### **Why is dependency management important for F# projects?**

Modern applications rely on open source components. Without proper visibility and governance, vulnerable dependencies can enter your software supply chain and increase risk.
