Protect Modern Infrastructure
Without Hardware Firewalls.

CloudArmour helps teams protect websites, APIs, cloud infrastructure, and gateways with software that fits the Linux environments you already run. Replace appliance-heavy deployments with a simpler operating model.

The problem

Five reasons security teams are looking for something better.

CloudArmour was built to solve all five.

Internet-facing services need better protection

Websites, APIs, SaaS platforms, and gateways are exposed to more abuse and attack traffic than ever.

Appliance models create cost and complexity

Hardware refresh cycles, vendor licensing, and site-by-site management make scaling security more expensive than it should be.

Infrastructure changes faster than old tools

Workloads move between cloud, edge, and on-prem environments. Security needs to keep up without rebuilding everything.

Security tools should be easier to operate

Teams need controls they can manage without specialist firewall expertise or a maze of disconnected consoles.

Too many tools create overhead

Separate products for cloud, on-premises, and Kubernetes mean duplicated policy, duplicated effort, and more to monitor.

CloudArmour solves all five.

One platform for modern infrastructure. Deploy on standard Linux, manage centrally, and move faster without appliance drag.

What We Solve

Stop Internet Threats Before They Reach Your Applications.

Whether you are protecting public services, cloud workloads, or distributed sites, CloudArmour helps you reduce risk without adding unnecessary complexity.

Gateway Firewall

Control traffic at the network edge. Stop malicious requests before they reach your services.

DDoS Protection

Reduce service disruption from volumetric and network-layer attacks.

Cloud Firewall

Protect cloud workloads and VMs across AWS, GCP, Azure, and hybrid environments.

Kubernetes Security

Secure ingress traffic, monitor runtime behavior, and enforce compliance across clusters.

Hybrid Cloud

Consistent security policy across cloud and on-premises deployments from one platform.

Branch Office

Protect distributed locations using standard Linux infrastructure instead of proprietary appliances.

Products

Flagship product: Neurowall.

CloudArmour's primary product is Neurowall — a gateway firewall for modern Linux infrastructure.

Why CloudArmour

Built for modern infrastructure.

Legacy firewalls were designed for a world of static datacenters and fixed perimeters. CloudArmour blocks unwanted traffic early, before it consumes application resources, across any cluster, container, or bare-metal host.

Other firewalls Neurowall
Speed Milliseconds Fast filtering at the network edge
Throughput Hardware-limited Designed to keep throughput high as policies scale
Automation Console-only or CLI scripts API-first operations
Threat feeds Manual import Auto-updated intelligence
Deployment Proprietary appliance VM, cloud instance, or bare metal
Built for Modern Infrastructure

No proprietary appliances. Deploy on standard Linux servers, virtual machines, or cloud instances — on infrastructure you already own.

Performance Without Complexity

Fast filtering that keeps traffic moving while enforcing security policies with minimal operational overhead.

Automation Ready

Manage infrastructure through APIs and automation pipelines. Fit security into existing workflows instead of replacing them.

Proof points

Specific. Tested. Credible.

Claims backed by numbers, not adjectives.

Throughput under load

Handles large policy sets without turning into a bottleneck.

More rules should not mean more operational drag. Neurowall is built to keep filtering fast as policy grows.

Large policy sets

Scales policy without forcing a platform change.

Allowlists, blocklists, and CIDR ranges can grow with the environment instead of creating a new product migration.

High availability

Active-passive failover in under 3 seconds via etcd leader election.

The standby node continuously syncs state and assumes the active role automatically when the primary fails — no manual intervention required.

Observability

Operational visibility your team can use.

Plug into Grafana dashboards and existing alerting pipelines. Health endpoints support Kubernetes liveness and readiness probes.

Time to first rule

A basic deployment with your first firewall rule can be completed in under 15 minutes on any Linux server, cloud instance, or VM.
