Accelerate Delivery. Block Threats
Artifact Firewall is part of the Varnish infrastructure suite: A high-throughput, programmable reverse proxy engineered for scale-intensive HTTP environments. Varnish deploys inline between client systems and upstream origins to accelerate, secure, and control data delivery at the network perimeter.
From securing CI/CD runners and governing AI workflows to optimizing Git, Varnish enforces traffic policy across on-prem, cloud, and containerized environments.
Scale Performance, Not Infrastructure
Reduce infrastructure strain, accelerate delivery, and maintain control across build pipelines, streaming, and enterprise systems.
Secure the Software Supply Chain
Intercept unverified dependencies
Enforce security policies across CI/CD and AI workflows at the request level.
Accelerate Artifact Delivery
Eliminate build-time bottlenecks
Cache container images and OCI artifacts at the edge to slash pull times.
Orchestrate Private & Sovereign CDNs
Deploy dedicated delivery infrastructure
Provision a self-hosted or SaaS CDN to keep control over UX, cost, and data residency.
Offload Git Traffic
Protect your origin from CI/CD runner spikes.
Collapse 1,000 runner requests into one, serving packfiles and LFS objects from the edge in microseconds.
Optimize Egress & Origin Load
Collapse redundant traffic into one upstream request.
Use request coalescing to protect databases and reduce cloud egress by 90%.
Accelerate AI Inference & Model Delivery
Stream and cache model weights.
Minimize cold-start times and lower total inference latency for LLM deployments.
Speed Up Object Storage Queries
Pre-fetch S3-protocol objects.
Reduce read-intensive cloud overhead and accelerate data-heavy application workloads.
Accelerate Web & API Performance
Optimize TTFB and offload requests.
Use edge caching and dynamic content composition to deliver sub-ms responses for websites and APIs.
For Platform Engineering & DevSecOps Leaders
Accelerate Global Build Pipelines
Varnish Orca co-locates your software registries at the cluster edge, ensuring machine-scale availability and eliminating CI/CD bottlenecks.
- 15 → 3 Minute Build Loops: Recapture engineering velocity by eliminating daily developer wait times for artifact pulls.
- 94% Data Transfer Reduction: Maximize Cache Hit Ratios to cut network data transfer costs by $1M+ annually.
- Zero-Downtime Resilience: Maintain continuous deployment velocity even during upstream supplier outages or registry failures.
For Infrastructure Architects & ML Platform Teams
Eliminate Data Stalls in AI/ML Workflows
Varnish accelerates AI/ML workloads by caching exabyte-scale datasets locally, ensuring compute cores never wait for storage data.
- 25% → 75% GPU Utilization: Triple effective compute capacity without provisioning more hardware.
- 99.7% Egress Avoidance: Pull training data exactly once; serve it locally with zero recurring data transfer fees.
- 75% Storage TCO Optimization: Focus performance tier spending strictly on active hot-data layer.
The Varnish Platform
Engineered for Performance Density
Built on the globally trusted foundation of Varnish Cache, our enterprise stack delivers hardened, multi-tenant performance management across bare metal, hybrid and multi-cloud topologies.
Varnish Enterprise
A high-throughput, programmable proxy layer that provides line-rate reverse proxying, load balancing, and edge security.
- Varnish Configuration Language: A domain-specific language transpiled to native C binaries at runtime for sub-millisecond request logic execution.
- Varnish Modules: Low-overhead extensions for executing advanced cryptography and complex header manipulation without performance penalties.
- Varnish-otel: Stream real-time metrics, traces, and structured JSON logs natively via OpenTelemetry directly to existing observability stack without introducing disk write or performance overhead.
