Developers request exceptions, and the team that owns your policy decides

Let one team, such as security, grant exceptions, while developers request what they need from the blocked install. Every request and decision is recorded in the audit log.

The API reference is now generated from the firewall's OpenAPI schema, with a page per operation and real request and response examples. The schema is public, so you can build your own tools on it.

newException requests: request an exception from a blocked install, review every pending request in one place, and route requests to your own tools with webhook events.
newDownload the OpenAPI schema to generate a client or import the API into your own tools.

Docker and OCI images now pass the same rules as your packages

Point Docker at a container firewall and every image you pull or push is checked on the way through. The OS packages inside it are matched against known vulnerabilities, and each layer is scanned for malware and leaked credentials.

Rust and Ruby teams can now put crates and gems behind the rules the rest of your dependencies already follow.

When something is blocked, the vulnerability or malware ID in the log entry now opens its page in the dashboard. You see the scores, whether it is known to be exploited, and what a malicious package does, without leaving to search for it.

newPull and push container images through a container firewall (beta), with vulnerability checks on the OS packages in each image and malware and secrets scanning of every layer. Enabled per organization on request.
newSearch advisories in the dashboard, and open a page per vulnerability with scores by vendor, EPSS, known-exploited status, the EUVD record, and every affected package.
newOpen the report behind a malware block, with what the package does, affected versions, and indicators of compromise.
newRoute Rust dependencies through a Cargo firewall (beta), with controls for vulnerabilities, yanked crates, licenses, release maturity, and malware.
newRoute Ruby dependencies through a RubyGems firewall, with controls for vulnerabilities, licenses, release maturity, malware, install-time code execution, and secrets scanning on publish.

Self-service trials, Composer, the CLI, and clearer firewall logs

You can now sign up directly and start a 14-day trial. PHP projects can install dependencies through a Composer firewall. The Bytesafe Dependency Firewall CLI has been released for macOS, Linux, and Windows. Firewall logs record upstream failures and can be filtered by outcome. Firewalls with a parent show their inherited configuration.

improvedView rules, exceptions, and upstreams inherited from a parent firewall in the dashboard and API.
improvedFind relevant firewall log entries with improved filtering.
improvedAdding rules is simpler: choose what you want to prevent, or start from scratch. See Delay new versions.
newStart a 14-day trial directly from the signup page, without requesting access first.
newRoute PHP dependencies through a Composer firewall (beta), with controls for vulnerabilities, abandoned packages, licenses, release maturity, and install-time code execution.
newThe Bytesafe Dependency Firewall CLI, bsfw, is released for macOS, Linux, and Windows. Install it with Homebrew, the install script, or a direct download.
newRecord upstream failures in the firewall log. Each entry identifies the registry and its response. Failures are logged even when another upstream serves the request.

The next generation: a firewall in front of your registries

The Bytesafe Dependency Firewall is a checkpoint in front of the registries your builds already pull from. Every install and publish passes your rules on the way through: block a package, filter it out of the version list, or delay it until the version has aged.

Rules act on what is known about a package, not just its name: vulnerabilities, malware, licenses, install scripts, and how long the version has been public. An exception waives one with a reason and an expiry.

improvedRules replace policies and plugins: one model combining an execution phase, a selector (name, version range, upstream, or a computed check), and an effect. Any rule can be scoped to one package, one prefix, or one upstream.
improvedExceptions carry a reason and an optional expiry, so a waiver is documented and ends by itself.
improvedRepository managers: run the firewall in front of, behind, or on both sides of Artifactory or Nexus.
newGo and Conda (beta) join npm, PyPI, Maven, and NuGet.
newMalware blocking on download.
newSecrets scanning on publish, so credentials do not leave in a package.
newTrust downgrade detection for npm releases published with weaker provenance than earlier versions.
newFirewall log and audit log: every decision with package, rule, and requester; every configuration change with who made it.
newWebhooks: signed events for firewall decisions, audit events, configuration changes, and publishes.
newTrusted Builders: GitHub Actions authenticate with their OIDC identity, no stored secrets in CI.
newConfig as code: firewall configuration in git, with rollback.
newThis documentation site. Start at the Quickstart or What is a dependency firewall?
