PRODUCT OVERVIEW

Say goodbye to network traffic jams and hello to smooth, fast data flows

Expanding into new geographic regions is great for the company but a headache for IT teams. Physical distance, unequal bandwidth capacities, traffic management, and inconsistent performance are just a few of the challenges. Paessler PRTG cuts through the noise of a dispersed network infrastructure with comprehensive monitoring that simplifies WAN (Wide Area Network) optimization.

Get rid of network congestion

The further away endpoints are, the higher the risk of high latency, delays, and poor application performance. Problems with routing paths add bottlenecks, reduce user experience, and cause IT teams to rant about inefficiencies.

PRTG helps you detect network congestions to create streamlined traffic flows – for smoother data transmissions and faster response times.

Maximize your bandwidth

If sometimes your network seems slow, you know inefficient bandwidth utilization can be like trying to fit a sumo wrestler into skinny jeans – uncomfortable and impractical.

PRTG WAN optimization can help save the day with detailed traffic analysis. Better informed capacity planning that gives you the best use of your available bandwidth while removing unnecessary upgrades? We understood that assignment.

Strengthen disaster recovery

Disaster recovery planning is essential in enterprise IT environments, but distance often makes backup operations slow. The higher the latency, the slower the data transfer.

Optimizing your WAN with PRTG helps to create an efficient data replication and backup process. Monitor important data to recover faster from disruptions, minimize downtime, and maintain business continuity.

Secure your organization

Network security is a constant battle against potential threats, unauthorized access, and data breaches. Managing a WAN makes security even more complex: monitoring traffic across multiple remote locations, ensuring secure data transmissions, and quickly identifying issues are all additional challenges.

PRTG adds muscle to your network security, providing comprehensive networking monitoring, immediate issue notification, and real-time traffic analysis.

Transfer more data faster

Throughput directly impacts your network's performance. It affects both the amount of data you can transfer at a time and the packet loss you experience.

With PRTG’s WAN optimization technology, you always have an eye on network traffic, making sure critical applications get the necessary bandwidth. And with higher throughput, end-users get an excellent experience, no matter where your network is located.

Get better data insights

When troubleshooting a network, you can never have enough data. Yet, the type of data matters. PRTG is a comprehensive network monitoring tool with a central dashboard that can drill down to the application process.

Whether you're looking at what you can do to optimize your WAN performance or figuring out why a part of your network is down, PRTG gives you the information you need for fast resolution.

What WAN optimization looks like in PRTG

Diagnose network issues by continuously tracking your wide area network. Show detailed network traffic and other key metrics in real time. Visualize monitoring data in clear graphs and dashboards to identify problems more easily. Gain the overview you need to troubleshoot network congestion and other inefficiencies.

5 reasons to choose PRTG for WAN optimization

Your network is made up of more than one type

Most networks, no matter how big, are made up of different types – not just wide area networks.

With PRTG, you can monitor several network types, including local area networks (LAN), virtual private networks (VPN), data center networks, cloud networks, industrial IT and OT networks, and more.

Monitor different providers at the same time

It’s rare for enterprise companies to rely on just one product or service provider. You’ll often find hybrid networks in multiple branch offices with systems that don’t work well together.

PRTG is excellent at working with others. It points out protocol incompatibility, gives you a lot of monitoring coverage, and works well with other network management and IT tools.

Benefit from a single, well-structured dashboard

PRTG is really good at network mapping. Its central main dashboard shows you your entire network, from a bird's-eye view to microscopic detail.

This user-friendly overview makes it easy to find issues, so you can address the problem area quickly. Real-time monitoring alerts you with proactive notifications before problems become critical.

You want simple, easy implementation

PRTG is also great at getting started in a matter of minutes. You can set up basic configurations with just a few clicks – no mess, no fuss, no PhD needed.

PRTG offers over 250 sensor types to monitor your entire network, many with preconfigured alert thresholds. No more spending multiple hours setting up network monitoring; we’ve done half the work for you.

Customize your setup the way you want

PRTG provides preconfigured sensors, but we know that monitoring a network isn’t a one-size-fits-all solution. You also want to automate as much as possible.

With PRTG, you can customize your dashboard view, sensors, thresholds, alert levels, and notification methods. Align your settings to support your unique network challenges, and let the automation happen!

WAN Optimization: FAQ

What is WAN optimization?

WAN optimization techniques are designed to improve data transfers across wide area networks, or WANs. WANs connect networks in multiple geographical locations, such as between different branch offices, data centers, or cloud services. The main goals of WAN optimization are to reduce latency, increase throughput, and make your network communications more reliable.

Why is WAN optimization needed?

There are many reasons for WAN optimization, but one of the largest is business continuity. In a fast-paced digital world, organizations can’t afford a slow network or, worse yet, downtime. WAN optimization directly targets the issues that cause network congestion, including limited bandwidth, high latency, packet loss, and multiple locations. With PRTG network monitoring, you gain valuable visibility into your WAN connections and overall network performance, giving you the knowledge you need to address issues and maintain a stable and secure environment from your WAN connections to your Microsoft operating system.

Does PRTG help with WAN acceleration?

While PRTG is primarily a network monitoring tool, it supports WAN acceleration by providing in-depth insights into network performance. Integrations with WAN acceleration devices and services make proactive management even easier.

Can PRTG support my SD-WAN solution?

Yes! PRTG can monitor most network components, including SD-WAN components. This configuration – PRTG in conjunction with an SD-WAN solution – is a common and complementary approach in many enterprises. It provides a holistic view of network performance and management.

What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive. On average, you need about 5-10 sensors per device or one sensor per switch port.

We asked: would you recommend PRTG? Over 95% of our customers say yes!

Paessler conducted trials in over 600 IT departments worldwide to tune its network monitoring software closer to the needs of sysadmins. The result of the survey: over 95% of the participants would recommend PRTG – or already have.
