Sonatype Repository Firewall
The package was malware. Your proxy should never have served it — Sonatype Repository Firewall checks every open-source package at the proxy — blocking malware before it is cached or served, and on the self-hosted edition quarantining suspicious packages until they are cleared.

Understand repository firewalls before you buy one
Most product pages skip this. We start here — so you buy a capability, not a buzzword.
What is a repository firewall?
A check at the proxy that decides, per request, whether an open-source package may be downloaded into your organisation at all.
Alerting after download vs blocking at the proxy — the honest table
What consolidation actually replaces, dimension by dimension.
| Dimension | Alerts after the package is in | Sonatype Repository Firewall |
|---|---|---|
| When malware is caught | After it is cached and built | At the proxy, before it is served |
| A suspicious package | Served until an advisory lands | Quarantined until cleared (self-hosted) |
| Internal package names | Open to namespace confusion | Public look-alikes quarantined |
| Exceptions | Allow-lists nobody reviews | Scoped, time-based waivers |
| Disconnected networks | Manual copies, unchecked | Air-gapped support via SAGE |
| What it is NOT | — | Not SCA for what is already in your apps |
The cheapest test: route one proxy repository through the firewall for two weeks and count what it would have stopped.
The five pieces of the platform
Vendors love diagrams; buyers need to know what they’re actually operating. Here’s the whole platform, demystified.
Intelligence
Every decision checks Sonatype’s own malicious-package data — the research behind its quarterly Malware Index, which logged 21,764 new malicious packages in Q1 2026 alone.
Proxy
Your repository manager’s proxy repositories fetch through the firewall instead of the public registry. A package is checked on request, before it is cached or served.
Policy
The self-hosted edition applies configurable policy on security, licence and quality at the point of download, and audits components already in the repository.
Quarantine
Suspicious components are held, not served. They are released by a waiver, an automatic release policy or a manual approval — or automatically once confirmed safe.
Malware research, an upstream proxy and quarantine — every package checked before your registry ever serves it.
Nine capabilities. Block, contain, govern.
Sonatype Repository Firewall stops malicious packages at the proxy — before your repository manager caches them or a build ever pulls them.
Known malware refused at the proxy
Blocks credential harvesters, backdoors, code injectors and typosquats before your repository manager caches or serves them.
In front of a registry you already run
Sonatype lists Artifactory, Cloudsmith, Azure Artifacts, GitLab, GitHub Packages and CodeArtifact. No software to install.
Hugging Face models checked too
Sonatype says the firewall evaluates AI and ML models from repositories such as Hugging Face for malicious code or risky behaviour.
Suspicious held, not just blocked
The self-hosted edition quarantines suspicious components before they enter, and releases them automatically if they are confirmed safe.
Namespace-confusion protection
It learns your internal namespaces from hosted repositories and quarantines any public package that claims the same name.
Docker images before download
Container protection on the self-hosted edition checks images and quarantines risky ones before a pull completes.
Rules set by risk level
Security, licence and quality standards are enforced at the point of download, with policy configured by risk level on the self-hosted edition.
Exceptions that are scoped and timed
Waivers can be time-based or scoped, so an exception for one team or one release does not quietly become a permanent hole.
Disconnected networks, via SAGE
The self-hosted edition supports internet-connected and air-gapped repositories; SAGE is Sonatype’s bundle for disconnected sites.

Book a guided demo →Most tools tell you malware got in. Repository Firewall stops it at the proxy.
Here’s what genuinely sets it apart — and exactly where it stops.
A published price to start with
Most package gates are quote-only add-ons to a larger platform. Firewall Pro lists at $4,800 a year and sits in front of the registry you already run — Artifactory, Cloudsmith, Azure Artifacts, GitLab, GitHub Packages or CodeArtifact — so a malware block does not wait for a platform migration.
Quarantine, not just a block list
The self-hosted edition holds suspicious components — not only known malware — and releases them automatically once confirmed safe, or through a scoped, timed waiver. It audits what is already in the repository and quarantines only new arrivals, so switching it on does not break existing builds.
The answer for regulated and disconnected sites
The self-hosted edition runs on your own servers and supports air-gapped repositories through SAGE, so policy, quarantine and audit data stay inside your perimeter. For an Indian bank or a defence supplier that cannot send traffic to a foreign cloud, that is the route to local control.
Where it stops
Firewall Pro covers four ecosystems, needs internet-connected repositories and is not for Nexus; quarantine, containers and air-gap are self-hosted only, and that edition is quote-only. Firewall Cloud hosting regions are not documented. It gates what enters — finding risk already in your apps is Sonatype Guide’s job.
The numbers behind the platform
What your Repository Firewall rollout looks like
Pick the edition by registry and formats
List your repository manager and ecosystems. Non-Nexus and only npm, Maven, PyPI or NuGet points to Pro; else self-hosted.
Route one proxy through the firewall
Point one proxy repository at the firewall and pull real traffic through it. Log what is blocked and who asked for it.
Audit first, then quarantine new arrivals
On the self-hosted edition, audit what is already cached, then quarantine only new components so existing builds keep working.
Set waivers, owners and namespaces
Decide who approves waivers and for how long, and register internal namespaces so public look-alikes are quarantined.
Extend to every proxy and format
Route every remaining proxy repository through the firewall, add containers and AI models if licensed, and review the blocks.

Quick poll — what’s driving your evaluation?
Talk to an advisor“We run Artifactory, not Nexus. Firewall Pro was a new upstream URL on four proxy repositories and an afternoon of testing.”
“Audit-first was the right call. It flagged what was already cached without breaking a single existing build on day one.”
“Namespace-confusion protection caught a public package squatting on one of our internal scopes within the first fortnight.”
“Our build network has no internet route. The self-hosted edition with SAGE was the only firewall on our shortlist that fitted.”
“Pro covers npm, Maven, PyPI and NuGet only. Our Go and Docker traffic needed the self-hosted edition, which meant a quote.”
“Quarantine released most held packages on its own once they cleared. The manual queue stayed small enough for one reviewer.”
Where everyone sits — the grids
Analyst firms bury this view behind paywalls, and G2 retired its Grid. So here’s TechBag’s synthesis of the package-security market — tap any vendor to see why it sits where it does.

Sonatype Repository Firewall is one of 35 developer tools products TechBag carries. The Developer Tools guide narrows them to a shortlist and shows the reasoning. →
What do malicious packages cost you once they are in?
Drag the sliders (developers; loaded developer-hour cost). Estimates model the time lost to malicious or risky packages found after they were downloaded — triage, cache purges, rebuilds and credential rotation — at an assumed 1.5 hours per developer a year, with 70% avoided by blocking at the proxy. Both figures are illustrative assumptions, not Sonatype data. Illustrative.
Loaded cost = salary + overheads per productive hour. Illustrative only — your TechBag quote models your actual environment and modules.
Three ways to consume it
Firewall Pro lists from $4,800 a year (country and local taxes excluded) for npm, Maven, PyPI and NuGet, on repositories other than Nexus and internet-connected only. The self-hosted Repository Firewall — 15+ formats, quarantine, container protection and air-gap — is quote-only. TechBag prices both against your registry and formats, then quotes in INR with GST.

The 8 questions to ask every vendor
Take this into your next vendor call — including ours.
Which repository manager do you run? Firewall Pro is for repositories other than Nexus; Nexus shops need the self-hosted edition.
Are all your ecosystems in npm, Maven, PyPI and NuGet? Go, Docker, Cargo and others need the self-hosted edition.
Is any build network air-gapped? Pro serves internet-connected repositories only; offline sites need self-hosted and SAGE.
Do you need suspicious packages held for review, or is blocking known malware enough? Quarantine is self-hosted only.
On self-managed Artifactory, will you use Pro or the self-hosted plugin? Sonatype’s docs say Artifactory SaaS is not supported by the plugin.
Who approves a waiver, how fast, and for how long? When waivers drag, developers tend to find a way around the gate.
Where does Firewall Cloud store logs and decisions? Sonatype does not document the region — get it in writing, or self-host.
Sonatype’s malware counts are its own research. Will the pilot measure blocks on your real traffic instead?
