Software-Defined Private Networks

Invisibility is the Ultimate Network Defense.

Remove your databases, APIs, and microservices from the public internet entirely. Neviri VPC creates logically isolated network perimeters where instances communicate freely—safe, secure, and invisible to scanning botnets.

The Flaw of Public-by-Default Infrastructure

Within minutes of provisioning a server with a public IP address, automated scripts map and probe it for open ports. OS-level firewalls help, but leaving critical databases directly exposed to the internet creates severe risks of misconfiguration, zero-day exploits, and compliance failures.

Neviri VPC isolates backend environments logically. We separate your architecture into a private software-defined space:

  • Zero Public Access for Databases & App servers
  • Single Secure Ingress Gateway at the Edge
  • RFC 1918 Private IP ranges (e.g. 10.0.0.0/16)

Defense mechanisms illustrated:1. Ingress Shielding: External port scanners cannot resolve private IP routing grids. Outbound NAT continues to work automatically for external updates (e.g. package management).

Software-Defined Infrastructure Controls

Neviri VPC offers enterprise security boundaries without requiring manual routing overheads or gateway calculations.

Zero-Trust Isolation

Assign non-routable private IPs (RFC 1918) like 10.0.x.x. External scanners cannot target or even locate your servers since they are literally invisible.

Intelligent IPAM Engine

No manual calculations of subnet CIDRs or setting up complex routing tables. Our software-defined network automatically configures gates and routes.

Line-Rate Throughput

VPC communication traverses high-speed physical data center fabrics at wire speeds. Low millisecond API exchanges and database queries.

Unmetered Bandwidth

All East-West traffic routing between servers, databases, and caches within the private VPC is completely unmetered, generating zero bandwidth costs.

Micro-Segmentation Support

Bind Stateful Cloud Firewalls to logical resource tags inside your VPC. Restrict internal ports so compromised instances cannot compromise database grids.

Secure Outbound NAT

Outbound requests (e.g., Stripe API calls) bypass ingress blocks safely using automated NAT gateways. Servers stay updated while remaining secure.

Multi-Tier Segmentation

Architecting the Modern DMZ

By segmenting resources inside different logical layers, your databases and core application servers remain protected from direct internet vulnerabilities.

Tier 1: Edge (Public)

Neviri Load Balancer

Exposed to the public internet (Ports 80/443). Serves as the single secure entrance. Cryptographic handshake processes are completed at the edge, protecting compute servers.

Tier 2: App (Private)

Application Servers

Compute VMs or Shared CPU instances inside the VPC. No public IPs assigned. Accepts sanitized requests forwarded exclusively from the edge Load Balancer over private subnets.

Tier 3: Data (Private)

Managed DB Tier

MySQL or PostgreSQL clusters provisioned deep within the VPC. Accepts connections originating strictly from Tier 2 IPs. Insulated against lateral threat movements.

Operations & Access

Seamless Deployment into the Void

Deploying code to private servers typically requires complex bastion hosts or fragile VPN tunnels. Neviri App Deployment solves this natively:

When you push code to GitHub or GitLab, our secure runners temporarily tunnel into your VPC using encrypted, ephemeral gateways. The build is deployed directly into the private network with zero public footprint required.

For manual access (e.g. db migrations), senior engineers can configure a highly restricted Bastion Host, using centralized SSH Key Injection to audit actions and secure administrative entry.

Strategic ROI of Private Networking

Frictionless Compliance Audits

Prove logical resource separation to satisfy SOC 2, HIPAA, and PCI-DSS compliance audits easily without configuring custom scripts.

Reduced Cyber Insurance Premiums

Routing traffic exclusively through load balancers and VPC perimeters drastically shrinks public threat surface area, lowering premium evaluations.

Zero-Cost Internal Bandwidth

Heavy internal replication, API requests, and storage traffic over Layer 2 fabrics are completely free and unmetered, ending billing surprises.

Frequently Asked Questions

Everything you need to know about private subnet routing, gateway structures, and database migration into Neviri VPC.

No. A VPC isolates incoming (ingress) connections from the public internet. By default, resources within a Neviri VPC can still initiate outbound (egress) connections to the internet (for example, if your Node.js server needs to ping the Stripe API or download an NPM package). This outbound traffic is safely routed through Neviri’s managed NAT layer, keeping the server's internal identity hidden while allowing it to fetch external data.

Currently, Neviri VPCs are designed as strictly isolated environments to ensure maximum security boundaries between separate projects or environments (e.g., keeping your 'Staging VPC' completely disconnected from your 'Production VPC'). If resources must communicate across project boundaries, they should do so via explicit, authenticated API calls routed through public or internal load balancing gateways.

No. At Neviri, we believe that foundational security should not be a premium add-on. The creation and management of Virtual Private Clouds, along with all the internal, unmetered bandwidth used within them, is provided at absolutely no additional cost. You only pay for the underlying Compute (VMs), Storage, and Edge Networking (Load Balancers) resources you provision.

If you have currently deployed Neviri VMs or databases on the public network, migrating them into a VPC requires a brief architectural shift. For databases, the safest path is to provision a new Managed Database inside the target VPC, establish logical replication from your public database to the new private one, update your application connection strings, and then safely decommission the public database. For stateless compute VMs, you simply update your deployment pipeline to target the new VPC, spin up the new private instances, attach them to your Load Balancer, and destroy the old public instances.
