1. PRTG – top-rated VPN monitoring tool for the hybrid work environment
License: proprietary license software
Supported vendors and applications: Dell, IBM, HP, ORACLE, APACHE, vmware, AWS, and Cisco.
Hosting: on-premise and cloud-based.
Supported OS: Windows, Mac, Linux, iOS, Android, and iPad.
Developer: Paessler AG.
With the advent of a VPN, employees working remotely can securely access company resources. Branch offices and mobile workers can seamlessly connect with the clients. Encrypted transportation of company data requires connection and network stability. PRTG can fulfill all these enterprise requirements.
On top of that, PRTG collects information about the VPN connection, such as which users used the VPN to connect to the company’s public network, the type of connection, and the volume of data transferred over a certain period. As a result, PRTG records connection problems and sends alerts to administrators in case of failed connection attempts.
Pros
- Continuous monitoring prevents intruders from exploiting security loopholes.
- Enable users to identify the root cause of problems quickly.
- Proactive troubleshooting streamlines the flow of traffic between VPN partners and company traffic.
- Easy to deploy and use.
- Gather data related to incoming and outgoing network traffic, the type and speed of data packets, connection errors, and connection types.
Cons
- Since the tool is specifically designed for the Windows operating system, it doesn’t work perfectly on the Linux OS.
2. Site24x7 – best for protecting the private network from intruders
Supported platforms: Windows, Mac, Linux, Android, and iOS.
Developer: Zoho Group.
License: free, commercial license.
Site24x7 flawlessly monitors VPN using its connections and tunnels using critical performance metrics like latency. As a result, users can enjoy a secure remote working experience. To unlock this SNMP VPN monitoring tool’s full potential, ensure that VPN devices and firewalls work optimally.
Sheer relying on the network monitoring tool to avoid congestion and offset potential malware threats is insufficient. However, using performance metrics, we must constantly monitor VPN and its associated devices. Here is a list of a few metrics that Site24x7 tracks:
- SSL login users: total number of users who have logged in to VPN over SSL.
- VPN sessions count: total number of active sessions.
- VPN bytes received: total number of bytes received over the endpoint.
- Active SSL sessions: total active secure socket layer (SSL) sessions.
Pros
- Site24x7 supports standard security compliances, notably ZyXEL ZyWALL 35 and Cisco ASA 5500 series.
- Monitor the performance of SNMP devices from any vendor.
- Generate personalized records tailored to the business needs daily, weekly, or monthly.
- Analyze VPN usage and critical metrics like peak hour for traffic and average traffic.
- Monitor Amazon VPN and Virtual Private Cloud connections.
Cons
- It requires some time to grasp the product.
- UI is not user-friendly.
