Compare between ManageEngine OpManager VPN Monitoring and other vendors

OpManager’s built-in VPN monitoring tracks the status, uptime, and performance of VPN tunnels on your network devices in real time. It alerts you to issues and shows traffic flow from a centralized dashboard, helping IT teams oversee site-to-site and remote VPN health across infrastructure. Unlike consumer VPNs, it’s designed for admin-level network visibility.

OpManager supports VPN monitoring for major device vendors like Cisco, Fortinet, WatchGuard, Palo Alto, Juniper, and SonicWall. It auto-discovers IPsec site-to-site tunnels and displays key details like encryption and hashing methods. While it tracks remote-access interfaces, it doesn’t show individual user sessions, though this can be handled by ManageEngine’s Firewall Analyzer. Overall, it covers most VPN tunnel types and device metrics out of the box.

OpManager offers flexible, real-time VPN alerts. You can set custom thresholds, such as tunnel downtime or abnormal traffic, and trigger alarms instantly. Alerts are sent via email, SMS, or team apps like Slack and Microsoft Teams. You can escalate unresolved issues, assign severity levels, and fully customize workflows to ensure the right people are notified quickly.

Yes, OpManager tracks VPN bandwidth by showing real-time Rx (receive) and Tx (transmit) traffic for each tunnel. It logs data transfer rates in Kbps/Mbps and offers historical graphs and reports. While it doesn’t run speed tests, it uses SNMP/API to monitor throughput, helping you spot bottlenecks or unusual traffic spikes. Related metrics like interface errors and latency can also be tracked for deeper insight.

OpManager is mainly offered as on-premises software, meaning you install it on your own server and retain full control of your data. You can deploy it on a local machine or host it on a cloud VM like AWS or Azure. While ManageEngine offers other cloud-based tools, OpManager itself isn’t a SaaS product. However, it supports remote access via web and mobile apps, allowing your team to manage the system from anywhere once securely configured.

Yes, ManageEngine offers a 30-day free trial of OpManager with full Professional/Enterprise features enabled. After the trial, it reverts to a Free Edition that allows monitoring of up to 3 devices—ideal for small labs or basic testing. For broader use, paid licenses start at $245 (Standard Edition, 25 devices). ManageEngine is also flexible with trial extensions or demo setups if you have specific evaluation needs.

OpManager doesn’t set a global VPN tunnel limit, but can monitor up to 100 tunnels per device. This is more than enough for most environments. If you have more tunnels, they’re typically distributed across multiple devices, which OpManager supports.

The platform scales to thousands of devices (especially in the Enterprise Edition), with tunnels displayed per device and in global summaries. As your tunnel count grows, system performance and deployment size matter more than hard limits.
