# Hats EPN | SD-WAN as a Service

**Hats EPN (Enterprise Private Network)** is a fully managed private connectivity service that delivers enterprise-grade WAN without the operational overhead of building and maintaining your own SD-WAN infrastructure.

> **Why Managed WAN?**
>
> Get all the benefits of Software-Defined Connectivity-traffic segmentation, predictable latency, and multi-site orchestration-without hiring specialized network engineers or managing complex edge devices.

## Why Managed WAN?

Most enterprises don't want to become networking companies. Here's how Hats EPN compares to the DIY approach:

| Aspect                      | Self-Built SD-WAN                           | Hats EPN (Managed)              |
| --------------------------- | ------------------------------------------- | ------------------------------- |
| **Setup Time**              | 3-6 months (hardware, config, testing)      | Days to weeks                   |
| **Expertise Required**      | Senior network engineers on staff           | Zero - we handle everything     |
| **Ongoing Ops**             | 24/7 NOC, patch management, troubleshooting | Included in service             |
| **Hardware Investment**     | CAPEX for edge appliances                   | OPEX only - no hardware to buy  |
| **Multi-vendor Complexity** | Integrating firewalls, SD-WAN, monitoring   | Single unified service          |
| **Scaling**                 | Manual provisioning, capacity planning      | On-demand bandwidth adjustments |
| **SLA Accountability**      | You own all uptime risk                     | 99.99% SLA with Hats Network    |

**Bottom line**: Focus on your business while we manage the network infrastructure.

### Cloud Access

Direct, optimized paths to major cloud providers. Your cloud workloads perform like they're on your local network.

* **AWS Direct Connect** integration
* **Azure ExpressRoute** connectivity
* **Multi-cloud** architectures with consistent performance

### Critical Workloads

When latency and jitter directly impact revenue, Hats EPN delivers the predictability that internet connections can't match.

* **Financial Trading**: Sub-50ms latency between trading venues
* **Healthcare**: Reliable DICOM image transfers for telemedicine
* **Real-time Collaboration**: Consistent video and voice quality

> **Benchmarks for Critical Workloads**
>

**No VRF configuration needed** - traffic segmentation is handled by our platform based on your requirements.

## FAQ

### What's the difference between Routed and Switched Private Network?

**Routed Private Network**: We manage the routing. You connect your edge device to our network, and we handle all the complexity of path selection, traffic segmentation, and optimization. Best for organizations that want "it just works."

**Switched Private Network**: We provide transparent Ethernet transport between your sites. Your routers see each other as directly connected on the same LAN segment. You manage all IP addressing and routing. Best for organizations with existing networking teams who want control.

Choose Routed for simplicity. Choose Switched if you have specific routing protocol requirements or need Layer-2 adjacency between sites.

### Can I use Hats EPN as an SD-WAN underlay?

Yes. Our SD-WAN Underlay option is purpose-built for this use case. We provide stable, measurable IP transport with consistent latency characteristics-exactly what SD-WAN solutions need for accurate path selection.

Benefits of using Hats EPN as your underlay:

* **Consistent baselines**: Your SD-WAN makes better path decisions with stable metrics
* **Reduced tunnel flapping**: No internet jitter causing unnecessary failover events
* **Guaranteed bandwidth**: Private backbone capacity independent of internet congestion
* **Simplified ops**: We maintain the underlay; you focus on overlay policies

Compatible with all major SD-WAN platforms including VeloCloud, Fortinet, Palo Alto, Cisco, and open-source solutions.

### How does traffic segmentation work?

Hats EPN uses Software-Defined Connectivity to create isolated traffic domains. Think of them as virtual networks that share physical infrastructure but never intersect.

Common segmentation patterns we support:

* **Environment Isolation**: Production, staging, and development as separate virtual networks
* **Traffic Type Separation**: Voice traffic on its own segment with priority treatment
* **Security Zones**: Guest networks, corporate data, and PCI-compliant traffic fully isolated
* **Departmental Segments**: Different business units with controlled interconnectivity

You define the segments. We handle the implementation-no complex configuration on your end.

### What does 'fully managed' actually mean?

With Hats EPN, you don't need network engineers on staff:

**We Handle**:

* Core network design and operation
* Routing protocol management and optimization
* 24/7 monitoring and incident response
* Capacity planning and scaling
* Software updates and security patches
* Peering and upstream relationships

**You Handle**:

* Your edge devices (routers, firewalls)
* Your internal LAN
* Your application configuration

You get a simple handoff at each site. Everything behind that is our responsibility.

### What are the latency commitments?

We provide baseline latency measurements during onboarding. Typical inter-PoP latencies on our private backbone:

> **Global Backbone RTT (Realtime)**
>
> For the full auto-updated RTT matrix across our PoPs (Backbone measurements), see: [Backbone
> Latency Matrix](/docs/network/latency)

| Route                 | Latency  |
| --------------------- | -------- |
| Hong Kong ↔ Tokyo     | 35-45ms  |
| Hong Kong ↔ Singapore | 35-45ms  |
| Tokyo ↔ Los Angeles   | 90-110ms |
| Frankfurt ↔ Amsterdam | 5-8ms    |

Our SLA covers latency variance (jitter) and packet loss, not just uptime. Because we control the backbone, we can guarantee performance characteristics that internet-based solutions cannot match.

### Can we connect to cloud providers?

Yes. Hats EPN integrates with major cloud platforms:

* **AWS**: Direct Connect via our partner locations
* **Microsoft Azure**: ExpressRoute connectivity
* **Google Cloud**: Dedicated Interconnect
* **Alibaba Cloud**: Express Connect

Cloud connectivity is integrated into your private network segments, creating seamless hybrid cloud architecture. Your cloud resources appear as just another site on your WAN.

### How quickly can we get started?

Typical deployment timeline:

| Phase            | Timeline  | Details                            |
| ---------------- | --------- | ---------------------------------- |
| **Discovery**    | 1-2 days  | Requirements, topology design      |
| **Contracting**  | 3-5 days  | Service order, terms               |
| **Provisioning** | 5-15 days | Circuit activation, cross-connects |
| **Testing**      | 1-2 days  | Validation, acceptance             |
| **Go-Live**      | -         | Production traffic                 |

**Total: 2-4 weeks** from signature to production - significantly faster than traditional carrier services.

Existing Hats Network customers can often add EPN services in days, leveraging existing infrastructure.
