Zero Trust Network Setup
VPNs were designed for a world where the network perimeter defined the trust boundary. That world no longer exists. Anubiz Engineering replaces VPN-dependent security with zero trust networking — where every connection is authenticated, authorized, and encrypted, regardless of whether it originates inside or outside your network.

Network Architecture Redesign
We redesign your network with zero trust principles: no trusted zones, no privileged network segments, no implicit allow rules. Every network flow is explicitly defined and enforced. East-west traffic (service-to-service) gets the same scrutiny as north-south traffic (external-to-service). We implement software-defined networking that makes the network topology irrelevant to the security posture.
Encrypted Transport Everywhere
All traffic is encrypted in transit — not just external traffic, all traffic. We deploy mutual TLS (mTLS) for service-to-service communication using service mesh (Istio, Linkerd) or direct certificate management. Database connections use TLS. Internal APIs use TLS. Even traffic between pods on the same node is encrypted. Packet sniffing on any network segment yields nothing useful.
Network Policy Enforcement
Kubernetes NetworkPolicies and cloud security groups implement default-deny with explicit allow rules for declared communication paths. We define policies as code in your Git repository, validated in CI, and applied through GitOps. Adding a new service requires declaring its network dependencies explicitly — there is no ambient network access. Policy violations are logged and alerted.
DNS and Service Discovery Security
DNS is a common attack vector in flat networks. We secure service discovery with authenticated DNS (DNSSEC), encrypted DNS queries (DNS-over-TLS), and service mesh-based discovery that bypasses DNS entirely for internal communication. Service endpoints are verified through certificate validation, preventing DNS spoofing from redirecting traffic to malicious endpoints.
