Unmatched Protection From Edge to Repository

Sonatype Firewall combines proprietary AI with the industry’s leading security research to safeguard your entire development ecosystem. By blocking malicious code, quarantining suspicious packages, and stopping unsafe components at the source, it reduces exposure to zero-day risks and prevents bad code from ever entering your environment. The result: fewer disruptions, less rework, and faster, more confident delivery of innovation.

Automatically Block Components That Don't Meet Your Standards

Enforce policies at the point of download, and block malicious packages, vulnerabilities, and licensing risks before they disrupt development.

Protect Any Repository

Sonatype Firewall uses proprietary AI and industry-leading open source intelligence to protect any repository from malicious code and vulnerable packages. It automatically blocks threats before they reach developer environments and CI/CD pipelines, working seamlessly with the tools you already use to prevent risk and eliminate rework. Go beyond standard repository security for protection that mitigates risk.

Nomura logo

“As open source vulnerabilities became increasingly problematic in recent years, particularly with Log4j, monitoring and enforcing software composition took on a greater sense of urgency. USPTO turned to Repository Firewall for the ability to block malicious code from the start.”

Spence Spencer

Office of the Chief Information Officer

See Full Customer Story

“We achieved our initial goals with incredible speed, moving from zero to a fully functional, secure, and scaled platform in the first quarter of the year. By May, the Sonatype Repository Firewall had actively quarantined vulnerable components, providing a clear, measurable example of risk reduction.”

Ali Syed

Senior Vice President Infrastructure

See Full Customer Story

“Sonatype Repository Firewall is the first line of defense in our toolchain. It prevents our developers from downloading insecure libraries, which saves time and reduces frustration. They now have more time for productive work and spend less time on repetitive routine tasks”

Tilo Riemer

Deputy Head of Information Systems

See Full Customer Story

“This proactive scanning reduces the amount of hidden work that developers were expected to perform to produce high quality secure code, and it allows that time to be reallocated and productively focused on building new features.”

Frequently Asked Questions

Why do I need protection from malicious packages?

Public open source repositories can be compromised, and developers are frequently targeted by malicious open source packages. Proactive protection stops malicious code from sneaking into your builds and reaching production systems.

What’s the difference between malware and vulnerabilities?

Vulnerabilities are accidental flaws in trusted software like unpatched bugs. Malware is intentional code crafted by attackers to cause harm. Most Software Composition Analysis (SCA) tools only detect known vulnerabilities and miss malicious behavior entirely. Sonatype Firewall is purpose-built to detect and block open source malware from the start, solving a different problem that traditional SCA tools can't address.

Does my perimeter or endpoint solution protect me from open source malware?

No. Perimeter and endpoint solutions aren't built to detect malicious code in open source software libraries and lack specialized malware intelligence. Sonatype Firewall uses our unique open source malware intelligence to proactively identify and block malicious open source components before it enters your development environment.

Does Sonatype Firewall require a repository manager?

No, Sonatype Firewall does not require a repository manager to work. It works with any repository manager like Sonatype Nexus Repository, JFrog Artifactory, Cloudsmith, Azure Artifacts, AWS CodeArtifact, Google Artifact Registry, GitHub Package Registry, and more. Sonatype Firewall can protect your software supply chain even without a dedicated repository manager. It integrates directly with security tools such as Zscaler for network-level protection and uses flexible APIs for seamless integration into custom workflows or existing CI/CD pipelines.

Is Sonatype Firewall compatible with existing network security tools?

Yes, Sonatype Firewall connects seamlessly with network security solutions such as Zscaler, extending open source malware protection to the network edge for comprehensive coverage.

Can Sonatype Firewall detect malware in AI/ML models?

Yes. Sonatype Firewall includes support from Hugging Face. Just like open source packages, these models are evaluated at the point of download to determine if they violate security policies or exhibit suspicious or malicious behavior. That means your data science and engineering teams can innovate with the latest models — confident that every download is secure and policy-compliant.

How quickly does Sonatype Firewall identify and block threats?

Threat detection and blocking happen automatically, in real time. As soon as a developer or system tries to download a malicious or policy-violating component — whether it’s a package, container, or AI model — Sonatype Firewall steps in to block it before it ever enters your development environment. Its advanced malware intelligence minimizes false positives so only true threats are blocked. In rare cases of uncertainty, components are quarantined for further analysis, and automatically released if deemed safe – ensuring developers aren’t stuck waiting on security.

Can Sonatype Firewall help with policy enforcement and waivers?

Yes, Sonatype Firewall Enterprise automates open source governance by quarantining non-compliant components. The powerful policy engine supports flexible policy waivers, including time-based and scoped exceptions, to balance security with development speed.

How often does Sonatype Firewall update its malware database?

Sonatype Firewall continuously updates its malware database, providing real-time protection against the latest open source threats.

What deployment options are available for Sonatype Firewall?

Sonatype Firewall supports flexible deployment options to meet different security and infrastructure needs. It is available as a fully managed SaaS offering for fast setup and minimal operational overhead. Organizations can also deploy it on-premises or self-hosted for greater control within their own environment. For fully disconnected environments, Sonatype Firewall Enterprise is supported via the Sonatype Air-Gapped Environment (SAGE).
