Modern Cybersecurity
for Modern Infrastructure.

CloudArmour helps teams protect modern infrastructure with high-performance security software built for Linux, cloud, edge, and hybrid environments. Replace appliance-heavy deployments with software that fits the infrastructure you already run.

The problem

Five reasons security teams are looking for something better.

CloudArmour was built to solve all five.

Internet attacks are increasing

DDoS attacks, credential stuffing, API abuse, and targeted intrusions are growing in frequency and volume. Internet-facing services are the first target.

Firewall appliances are expensive

Traditional hardware firewalls require proprietary equipment, vendor licensing, and hardware refresh cycles every 3–5 years — costs that multiply across every site.

Cloud infrastructure changes quickly

Workloads move between cloud providers, regions, and deployment models faster than appliance-based security can follow. Policies fall out of sync.

Security tools have become too complicated

Most enterprise firewall platforms require specialist knowledge to configure, operate, and maintain. Complexity slows response and increases the chance of misconfiguration.

Multiple products increase overhead

Running separate firewall tools for cloud, on-premises, and Kubernetes means multiple consoles, multiple policies, and multiple failure points to monitor and audit.

CloudArmour solves all five.

One platform. Standard Linux infrastructure. API-first management. Deployed in under 15 minutes.

What We Solve

Stop Internet Threats Before They Reach Your Applications.

Whether you are protecting a public website, SaaS platform, Kubernetes cluster, or enterprise network, CloudArmour helps you reduce cyber 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.

Gateway Firewall & DDoS Protection
Neurowall
Beta '26

Protect internet-facing infrastructure with a high-performance gateway firewall designed for modern Linux environments. Neurowall combines centralized policy management, integrated threat intelligence, and flexible deployment across cloud, on-premises, and hybrid environments.

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 Kernel-level packet processing
Throughput Hardware-limited Full ISP line rate maintained with 272K+ rules loaded
Automation Console-only or CLI scripts Full REST & gRPC API
Threat feeds Manual import Auto-updated, pushed to kernel
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

High-performance packet filtering that keeps network throughput high while enforcing security policies with minimal operational overhead.

Automation Ready

Manage infrastructure through REST APIs, CLI tools, 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

Maintained full ISP line rate with 272,000+ active rules loaded. No throughput reduction.

Rule count has no measurable impact on throughput. Adding more rules does not slow down packet processing.

Large policy sets

Supports large allowlists, blocklists, and CIDR policies without measurable throughput reduction.

Tested in initial ISP-limited conditions. Allowlists, blocklists, and CIDR ranges scale without degrading packet processing speed.

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

70+ Prometheus metrics covering packet counters, rule sync, eBPF map utilization, and API health.

Plug directly 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.
