Dependency Firewall

Block malware by inspecting every package before it reaches any system or user in your company, including developers, and local or cloud AI agents operated across every team.

Dependency malware firewall diagram showing developers, AI agents, and package registries.

A malicious package can compromise your company the moment it is installed, because its scripts run before any of the code reaches production. A single install by any user is enough to leak credentials, plant a backdoor, or hand over source code before anyone notices.

Stop malware before it reaches anyone in your company

One firewall for every install in your company

Dependency Firewall blocks malware from reaching your developers and the AI agents your teams use, like Codex, Claude, and Antigravity, whether they run locally or in the cloud.

Catch malware before it’s installed

depthfirst analyzes every newly published package the moment it lands on a public registry, so malicious packages are stopped from being installed.

Enforce custom policies

Define what your company will accept, from package attributes to license terms, and Dependency Firewall enforces it on every install.

How Dependency Firewall blocks malware

depthfirst immediately scans every new package release, reasons about its intent, and verifies its behavior to provide higher recall and precision on malware detection.
Deploy Dependency Firewall upstream of your private registry or artifact repo, so every package is inspected before it enters your trusted store.
Dependency Firewall sits between every endpoint and the public registries they pull from, so installs that bypass your artifact repo, or companies that do not have one, are protected too.

We recently had an incident where an internal vibecoded app inadvertently pulled in a malicious package that put our company at risk. depthfirst’s Dependency Firewall is a game changer as it enables us to safely leverage AI across the company.

F100 CISO

Designed to fit your policies and workflows

Configurable guardrails

Define what your company will accept, from package attributes to license terms. Require a minimum package age, gate specific dependency trees, and enforce license policies across direct and transitive dependencies.

Response workflows

Route verdicts into the systems your team already uses, with critical detections paging through your incident response system and quarantines opening review tickets automatically.

Full control for security teams

Your team can override the decision in seconds, with every override logged automatically.

Security without latency

Approved packages are cached automatically so future installs add no latency.

Goodbye siloed security. depthfirst uses the same core technology to secure every layer of your system.

Code

Find real vulnerabilities by tracing business logic, data flows, and cross-service interactions across your codebase.

Supply Chain

Trace risk through your full dependency tree and surface only the vulnerabilities with a real execution path to them.

Secrets & Sensitive Data

Detect and validate credentials across your codebase, CI/CD pipelines, and runtime environments.

Agentic Pentesting

Confirm which vulnerabilities are exploitable by testing your running application with real attack paths.
