In their own words
Greymatter
Greymatter is a Zero Trust Networking platform for controlling, connecting, and securing applications, APIs, and AI workloads. Its architecture has analytics, zero trust, service connectivity, orchestration, and enterprise-integration layers. Deployments can run across AWS, Azure, GCP, Oracle Cloud, sovereign clouds, Kubernetes distributions, virtual machines, edge environments, and disconnected settings. Greymatter automates workload identity provisioning, applies mutual TLS, and uses NIST-validated FIPS 140-3 cryptography, CMVP #5191. GitOps Playbooks manage traffic policies across clusters with autonomous updates and zero-downtime changes. Deployment options include canary, blue-green, and progressive delivery with health checks, fallback logic, and rollback. Analytics integrates with Grafana, Kibana, Prometheus, Splunk, Elasticsearch, SIEMs, and APMs. Identity integrations support OAuth2, OIDC, and PKI, including Keycloak, Ping Federate, Okta, and Auth0. It offers hybrid deployment, enterprise support, and a 30-day free trial.
Tetrate Service Bridge
Tetrate Service Bridge is a paid, hybrid service mesh and control plane for connecting, monitoring, and securing microservices. Built on Istio, it centralizes Istio and Envoy configuration and visibility across Kubernetes and traditional compute clusters, including application edges, cluster ingress, and links between workloads. A global management plane spans multi-cluster hybrid environments. Security controls include end-to-end mTLS, certificate management, identity-aware authorization, role-based access control, tenant isolation, and zero-trust policies with auditability. Traffic features cover global routing, circuit breaking, locality-aware failover, canary releases, traffic shifting, and blue-green deployments. Unified metrics, distributed tracing, topology views, service inventory, dashboards, and alerts provide observability. Tetrate lists support for Kubernetes, AWS EKS, Azure AKS, and Google GCP, plus integrations and partners across major cloud and infrastructure providers. The management plane may be hosted by Tetrate or deployed in customer Kubernetes infrastructure. Self-managed installation requires Kubernetes and several supporting services. Pricing is on request; no free plan is listed.
