See it in action
Isolation breaches, audit failures, and hidden network costs — all invisible until Netway finds them. One CloudFormation stack deployed into your AWS account. Daily scans. Actionable findings.
Deploys in 5 minutes · No agents · No code changes · Works with existing AWS accounts
These patterns exist in most AWS environments that have grown past a handful of VPCs. The problem isn't misconfiguration — it's invisibility.
Production and staging connected through a VPC peering nobody documented. The path exists. Traffic can flow. Nobody in the room knows it's there.
Your PCI-scoped environment is reachable from a non-PCI network. Your QSA will find it before you do. The worst part — the controls were in place. The network grew around them.
S3 traffic routing through NAT when a free VPC endpoint exists. The default private subnet setup does this. Every new service does it without knowing. It compounds at scale.
None of these announce themselves. Each one grows silently — until an incident, an audit, or a bill makes it unavoidable.
Netway addresses all three. One Lambda deployed into your AWS account. No agents, no IAM users, no persistent access, no code changes.
Each pillar maps directly to a class of risk your team is carrying right now.
Interactive graph of your VPCs, Transit Gateways, peerings, and internet gateways — across all accounts and regions. The graph shows reachability between VPCs visually. Switch to the Matrix panel for a full reachability grid across all VPC pairs.
TOPOLOGYSelect two environment groups (e.g. production and staging) — Netway evaluates whether any network path exists between them on every scan and maintains 365 days of proof. Generate a signed PDF evidence report for PCI-DSS and SOC2 audits with one click.
COMPLIANCEDetectors scan your VPC flow logs for avoidable network spend — S3 via NAT, cross-AZ database traffic, GPU workloads routing through internet gateways, and more. Each finding includes monthly dollar amount and exact fix.
COSTNo agents. No code changes. No access to your application.
One CloudFormation stack deploys a Lambda function into your AWS account. The Lambda is open source — audit it on GitHub before you deploy.
5 minutesLambda scans your VPC topology (VPCs, TGWs, peerings, subnets, compute instances) and analyses VPC Flow Logs for traffic patterns. Runs daily.
AutomaticNetway runs topology detectors (isolation rule evaluation, CIDR conflicts, CDE exposure, compliance checks) and cost detectors (traffic waste patterns) on every scan result.
Per scanDashboard shows your live network graph, compliance status, and cost findings. Violations trigger Slack alerts immediately. PDF compliance report available on demand.
Per finding
Netway detects multiple categories of avoidable network spend — from the most common to ML-specific patterns.
High-volume data leaving your VPC directly to the internet at $0.09/GB. CloudFront reduces this to under a cent per gigabyte.
GPU training jobs writing model checkpoints to S3 through NAT. The data volumes are 10x larger — so is the waste.
Workloads reading from S3 buckets in another region pay $0.02/GB in cross-region transfer fees plus added latency.
Multi-GPU distributed training with nodes in different AZs. Every gradient synchronisation is a cross-AZ transfer charge.
Your workloads are paying internet transfer rates to access your own S3 data. A free VPC endpoint eliminates this entirely.
Model weights loaded from S3 on every inference cold start via NAT. A VPC endpoint cuts both the cost and the cold start latency.
Application servers in one availability zone querying a database in another. Every query is charged at $0.01/GB each way.
Calls to SSM, CloudWatch, Secrets Manager, and STS going through your NAT Gateway — for traffic that never needs to touch the internet.
Instances routing to a NAT Gateway in a different AZ pay both NAT processing and cross-AZ transfer fees on every outbound byte.
