Bytesafe vs. Sonatype Repository Firewall
Bytesafe works in front of any registry, publishes its full price list, and is hosted in the EU by default. Sonatype Repository Firewall requires Nexus Repository as the proxy layer.
Published by Bytesafe. Based on Sonatype Repository Firewall's public documentation as of 2026.
Sonatype Repository Firewall is the natural option if you run Nexus Repository. The reasons teams look beyond it: it requires the full Sonatype Platform subscription, pricing scales with users and usage, or they are looking for an EU-hosted alternative.
A different approach to Dependency Firewall pricing and deployment
- The firewall is the product.
- Bytesafe is a dependency firewall. There is no larger platform to buy into, no scanner to license separately, no monitoring toolchain bundled in. One product, one job.
- One meter sets the price.
- Active users, packages scanned and downloads served are all measured, and only the largest one is charged. The other two are included at the same size. From EUR 99 a month, with the whole price list published.
- Works with your full registry stack.
- Proxy npm, PyPI, Maven, NuGet, Go, Composer, Cargo, Conda, and containers from any source: Nexus, Artifactory, GitHub Packages, Azure Artifacts, or public registries. One firewall across your whole stack, not just the Nexus-proxied portion.
- EU-hosted and EU-based.
- Hosted and operated in Sweden. EU data residency is the default, not a deployment option or additional cost. No US data transfer for package metadata or policy decisions.
What Sonatype Repository Firewall is
Sonatype Repository Firewall intercepts package requests at the Nexus Repository proxy layer, evaluating each package against Sonatype's malicious package intelligence database before it enters your environment. It is designed to block malicious packages automatically at download time, without requiring manual review of every request.
The firewall is part of the Sonatype Platform, which also includes Lifecycle for vulnerability and license policy enforcement across your supply chain. If your organization already runs Nexus Repository, the firewall can be added to that infrastructure and benefits from Sonatype's package intelligence data.
The constraint is architectural. Sonatype Repository Firewall works primarily through Nexus Repository as the proxy. Artifactory can be integrated but requires additional configuration steps. GitHub Packages, GitLab Packages, and Azure Artifacts are not supported. The purchasing decision is also tied to the broader Sonatype Platform, not scoped to the firewall capability alone.

Key differences
No registry lock-in
Bytesafe proxies any upstream from a single endpoint: npm, PyPI, Maven Central, NuGet Gallery, Go module proxies, Packagist, OCI registries, and enterprise platforms including Nexus, Artifactory, GitHub Packages, and Azure Artifacts. One firewall policy across your full stack, regardless of what sits upstream.
Sonatype Repository Firewall: Sonatype Repository Firewall works through Nexus Repository as the proxy layer. Artifactory can be integrated but requires additional configuration. GitHub Packages, GitLab Packages, and Azure Artifacts are not supported.
One meter, and a published price list
Bytesafe measures three meters and charges for the largest. There is no overage: a heavy month raises the plan size while it lasts and settles back as it ages out. Every price is published, and the firewall is sold on its own.
Sonatype Repository Firewall: Sonatype Platform pricing most often includes per-developer licensing. The firewall is not available as a standalone subscription separate from the broader platform.
EU hosting as default
Bytesafe is hosted and operated in Sweden. EU data residency applies to package metadata, policy decisions, and audit logs without any configuration. There is no US fallback.
Sonatype Repository Firewall: Sonatype is a US-headquartered company. Sonatype's cloud platform region availability varies. EU data residency most often requires deploying Nexus Repository on-premises in your own EU infrastructure.

When Bytesafe makes sense
- Your registry stack includes Nexus, Artifactory, GitHub Packages, Azure Artifacts, or public registries — or several of these. Bytesafe works in front of all of them from a single endpoint.
- A single price based on the largest of three usage meters matters. Bytesafe publishes the full price list and does not charge overage.
- EU data residency by default is a requirement, not a configuration option or added cost.
- You want a standalone Dependency Firewall without a full platform subscription.
- You want lightweight, independent firewall configs per team or environment, managed in Git.
