VPN Monitoring and Testing

Virtual Private Networks (VPNs) have become a necessity.
Ensure VPN performance and availability with synthetic and real-user monitoring

Virtual Private Networks provide secure and encrypted traffic across the public Internet

VPNs have become a necessity for modern businesses, especially post pandemic with the growth of remote and hybrid work. A Virtual Private Network enables secure and encrypted traffic across public networks and the Internet.

Often, though, corporate VPNs are a source of frustration for employees with poor performance, incorrect configuration, and increased latency or response times.

Primary Use Cases for Business-class Virtual Private Networks

Security Icon

Enhanced Security

VPN connections transmit encrypted data between the user’s device and company networks.

Geographical Restrictions

VPNs allow access to resources by bypassing geographical restrictions in far away places like APAC.

Secure remote access icon

Secure Remote Access

VPNs allow for secure access to company data, resources, and applications.

Data privacy compliance icon

Data Privacy Compliance

VPNs ensure compliance with data privacy laws and enforce secure access to data.

Zero Trust Network Access icon

Zero Trust Network Access (ZTNA)

VPNs are a key component of ZTNA and provide user and policy enforcement.

VPN Monitoring and Control icon

Monitoring and Control

VPNs provide monitoring and access control to corporate resources.

Importance of Monitoring, Testing, and Assessing VPN Connection Performance

Companies require VPNs to safeguard data, facilitate remote access, ensure compliance, and maintain control over network security and internet usage. Private communication channels over VPNs play a critical role in business operations wherever users work.

VPNs also enable Bring Your Own Device (BYOD), promoting secure application access when not using a company sanctioned device. This allows organizations to monitor and enforce secure policies without being intrusive.

While VPNs provide great benefit to security, they add many layers of complexity to network access and are often detrimental to employee digital experience.

Reduced Speed, Increased Latency icon

Reduced Speed

Internet connection speeds are impacted by VPNs due to servers, encryption, and decryption. VPN bottlenecks vary depending on server load, ISPs, and VPN providers.

VPN Capacity Issues icon

VPN Capacity Issues

VPN services, SDWAN, and SASE infrastructures frequently require capacity adjustments to ensure capacity and performance during peak usage.

VPN Compatibility Problems

Applications and services can be incompatible with VPN services and require assessment and testing. Compliance, security, and location dependencies should be evaluated.

VPN Blocking Websites icon

Blocked By Websites

Some website services can actively block VPN traffic. When using certain VPNs, users may find themselves not able to access the resource in this case.

Network engineers can continuously test, monitor, and benchmark their business VPN solutions within minutes.

VPN Configuration Complexity Causes VPN Performance Issues

Split tunneling and VPN route manipulation is the source of mistakes, slow performance, and employee frustration. When routing is configured to shape or steer, packets from network sensitive applications like UCaaS can be misdirected through or around the VPN.

Organizations sometimes fail to correctly configure split tunneling and VPN routing. This can lead to poor performance or slow application access. For example, configuring Teams traffic to pass through the VPN instead of routing directly to Microsoft relay servers leads to poor Teams audio, video, or app sharing quality.

Whether an organization uses remote access or site-to-site VPNs, intranet-based or extranet-based VPNs — even personal VPNs — Exoprise proactively tests and monitors the performance and reliability. With the combination of Service Watch RUM and CloudReady synthetics, Exoprise delivers a holistic view of VPNs and routing.

VPN Monitoring Dashboard

Service Watch — Real-User Monitoring for VPNs

Service Watch Desktop provides detailed telemetry into how applications are accessing the network internally, externally, and across the Internet. It collects metrics critical to diagnosing VPN issues:

Whether employees are working in the office, hybrid, or remote, Service Watch provides detailed diagnostics into the network path performance of VPN clients.

VPN Client Overhead

VPN Client Utilization

Capture and continuously record the overhead and resource utilization of VPN clients (CPU, Memory, paging, handles, buffers, etc.)

Network Latency, Jitter, and Packet Loss for VPNs

VPN Latency, packet loss, jitter

Service Watch can monitor VPN latency, jitter, packet loss and hop-by-hop path performance for any protocol and destination servers.

Speed Testing VPNs

Synthetic testing and traffic generation for load-testing or performance monitoring of VPNs is simple with Exoprise CloudReady synthetics. Network tests can be deployed in peer-to-peer, hub and spoke or to any users desktop to provide proactive notifications integrated with any system.

VPN Ping Synthetics

Ping Synthetics for VPNs

Ping network addresses for continuous performance and availability monitoring

VoIP VPN Synthetics

VoIP Codec Tests for VPNs

Send and receive UDP / VoIP packets between nearest Exoprise or customer VoIP recievers

DNS Lookup Tests for VPNs

Test DNS resolution, routing, split tunneling, and performance over VPNs

WGET Tests for VPNs

Monitor availability and response times of corporate sites behind the VPN

Secure Access Service Edge Monitoring

Secure Access Service Edge (SASE) has become an important initiative for enterprises along with Zero Trust Networks. SASE, Cloud Access Security Brokers (CASB) and cloud proxies combines wide-area networking (WAN) with network security to secure access to corporate and cloud assets.

SASE platforms require testing and impact the employee digital experience. Adding extra network layers, hops, authentication and security inspection will slow access for employees. Exoprise synthetics are designed to be able to proactively test and monitor SaaS applications wherever SASE access is implemented. The network telemetry collected for applications by Service Watch will also reflect the app performance impacts from SASE.
