The Greymatter Service Connectivity Layer
Service Connectivity
Without the Complexity
Greymatter’s Service Connectivity Layer runs policy aware service communication across clouds, clusters, and networks—without constraints.
4th Consecutive Year at the Top
Secure Connectivity. Independently Proven.
GigaOm named Greymatter a 2025 Leader for its mission-grade approach to secure service-to-service connectivity—automating zero trust policy enforcement across VMs, containers, and edge without rewriting a single line of config.
Next-Gen Connectivity and Control
Secure, Smart, Seamless Intelligent Networking for a Connected Enterprise
The Greymatter SCL transcends connectivity—delivering control, insight, and automation in one powerful platform. Here’s how we power enterprise scale excellence:
Envoy Control Without the Overhead
Greymatter uses ightweight control planes to manage Envoy proxy behavior in real time. Engineers define listeners, filters, and routing logic with GSL Playbooks—no raw YAML, no hand-rolled configs. Policies push automatically via GitOps, keeping traffic rules consistent, auditable, and rollback-ready.
Cross-Cluster Mesh Federation
Greymatter connects clusters into a single, policy-aware mesh using managed mTLS and trust propagation. Services communicate securely across clouds and domains without overlay networks or manual stitching. Teams control global routing and failover from one unified layer.
Live Traffic Routing & Failover
Greymatter applies routing rules and failover logic at runtime, using real time active and passive health checks and metrics. It shifts traffic dynamically around failed nodes, overloaded paths, or policy violations, without redeploys or manual intervention. Reliability is built in, not bolted on.
Inline Filter Chains for Logic
Greymatter runs inline filters, WAF rules, and custom logic directly at each managed proxy. Teams inspect, shape, and secure traffic inline—without touching app code. Policy updates flow from the control planes and apply instantly across the mesh.
Policy-Driven Networking, Not Manual Ops
Smart Service Connectivity with
Built In Zero Trust Security
Greymatter isn’t just about connecting services—it’s about empowering enterprises with full control, intelligence, and automation across every layer of the application network. Here’s how we deliver:
Unified Mesh Policy
Greymatter governs traffic, trust, and zero trust compliance through declarative Playbooks tied to GitOps workflows. These policies control routing logic, filter behavior, and service access across Kubernetes clusters and Clouds Service Providers. The control planes synchronize updates in real time, ensuring policies are always enforced and auditable. No need to maintain config drift or chase broken rules across environments.
Dynamic Failover Routing
Greymatter detects service health and route quality in real time and adjusts traffic accordingly. It reroutes around failures, avoids high-latency paths, and applies circuit breakers, retry logic, bandwidth limitations and flow control based on runtime signals. Teams define failover behavior once—Greymatter enforces it continuosly. Users experience uptime; teams skip the war rooms.
Zero Trust Transport
Greymatter enforces encrypted and authenticated communication by default, using mTLS and NPE certificates managed through automation. It handles issuance, rotation, and revocation automatically while integrating with OCSP stapling and CRL checks. This builds continuous zero trust posture into every hop. Operators don’t need to touch certs—Greymatter manages the full lifecycle.
Mesh Federation Without Fragmentation
Greymatter connects clusters into a unified, policy-enforced connectivity layer that connects distributed service mesh architectures without requiring custom brokers or third-party federation layers. It handles service discovery, trust bridging, and routing across clusters as part of its default behavior. Operators connect mesh segments using zero trust handshakes and Greymatter ensures it stays in sync. One connected mesh network, no silos.
Inline Enforcement. Zero App Changes.
Greymatter injects policy at the proxy level using filters that include WASM, LUA, and WAF modules that come by default, allowing for OWASP CRS protection, payload validation, and custom logic execution inline. Teams can modify runtime behavior live without app changes. These controls enhance both security and agility. From custom logic to standardized protection, Greymatter handles it.
Connect Smarter. Scale Faster. Secure Everything.
Greymatter gives engineers fine-grained policy control with automation that works at runtime. Listeners, filters, gateways, sidecars, trust, and routing—coordinated in one platform.
