OpManager has been recognized in industry publications and awards, for example, it was named a Network Management Solution of the Year winner and praised for delivering enterprise-level features at SMB-friendly pricing and enabling smarter network management. The solution is also highly rated on user review platforms (as detailed later in this review), reflecting ManageEngine’s positive standing among their customers. Overall, the company’s long history, global client base, and consistent product improvements (including recognition in Gartner’s Magic Quadrant reports for IT management) underscore their credibility in the network monitoring space.

Features & Services

Core VPN monitoring capabilities

• Real-time tunnel status: Continuously monitors VPN tunnels (up/down status and uptime) for instant visibility into outages
• Site-to-site VPN monitoring: Tracks branch-to-branch VPN links and displays overall health via VPN Summary widgets
• Remote access VPN support: Can be extended (with Firewall Analyzer) to monitor individual VPN users and remote access protocols

Device compatibility and vendor support

• Multi-vendor compatibility: Works out of the box with Cisco, Fortinet, Palo Alto, WatchGuard, Juniper, SonicWall, and others
• Automatic tunnel discovery: Detects and starts monitoring VPN tunnels upon discovering compatible firewall devices, no scripts needed
• Vendor-specific performance polling: Uses SNMP/API to collect status, throughput, and health metrics tailored to each vendor

Performance metrics and alerts

• Traffic monitoring: Tracks real-time Rx/Tx traffic and bandwidth usage across tunnels
• Security protocol visibility: Identifies encryption and hashing algorithms (e.g., AES-256/SHA-2)
• Threshold-based alerts: Notifies you when traffic stops, spikes, or falls below defined limits via email, SMS, or messaging apps

Visualization and reporting

• Custom dashboards: Use over 200 widgets to create tailored views, such as a world map of VPN status or traffic trends
• VPN summary reports: Aggregates long-term availability and performance data across all tunnels
• Historical trend analysis: Stores raw performance data for up to 180 days (based on edition) for capacity planning and analysis

Automation and integration

• Workflow automation: Automate actions like restarting services, running scripts, or creating tickets when a tunnel fails
• Team collaboration integrations: Sends alerts to platforms like Slack and Microsoft Teams for instant team notifications
• Mobile monitoring: iOS/Android app available to track VPN status and receive alerts on the go

Unified network monitoring

• Cross-service correlation: Correlates VPN issues with hardware, server, or connectivity problems across your infrastructure
• Full network visibility: Monitors devices, interfaces, servers, apps, and wireless APs from one console
• Topology mapping: Automatically maps VPN tunnels within the broader network to visualize impact in context

VPN protocols and speeds

ManageEngine OpManager monitors IPsec-based site-to-site VPNs at the network level, showing encryption/hashing details (e.g., AES-256/SHA-1) to help enforce security compliance. It alerts if outdated ciphers (like DES/MD5) are detected. For performance monitoring, it tracks real-time Rx/Tx throughput (Mbps/Kbps), helping identify bottlenecks or failures via threshold alerts (e.g., spikes/drops to 0). However, it doesn’t route traffic—only monitors existing VPNs.

While OpManager focuses on device-level monitoring (SNMP/API), it may not list all protocols (e.g., OpenVPN/SSTP), but it still tracks tunnel availability. For per-user VPN metrics (connected users, bandwidth), pairing with Firewall Analyzer is recommended. In short, OpManager optimizes site-to-site VPN performance/security and integrates with other tools for broader coverage.

Security & Privacy Measures

• Encrypted data: Uses SNMP v3 and HTTPS to secure device polling and web access
• SSO support: Integrates with SAML providers like Azure AD and Okta for secure logins
• Role-based access: Set user permissions by role; all actions are logged
• Security guidelines: Built-in recommendations for hardening passwords, 2FA, and policies
• On-prem deployment: All monitoring data stays in your environment, nothing is sent to third parties
• Compliance: Zoho Corp (parent company) is ISO 27001 certified; regular security patches issued
• Backup and storage: Supports encrypted backups and MSSQL data encryption

Disadvantages

Steep learning curve: Basic monitoring is easy to set up, but mastering advanced features takes time. With so many options, the interface can feel overwhelming for new users. Smaller IT teams may struggle initially, though ManageEngine offers AI training and support to ease the process.

Extra cost for advanced modules: Core features, including VPN monitoring, are included in the base license. However, add-ons like NetFlow, config backups, or APM require additional purchases. Some users find it frustrating when features in the UI prompt for license upgrades unexpectedly.

Long-time users have praised this responsiveness, with some noting they’ve seen steady improvements over several years of use. To address complexity concerns, ManageEngine offers detailed documentation and free training webinars. Users who once felt they weren’t using the tool to its full potential appreciated these resources, seeing them as a sign that the company is actively helping customers get more value from the product.

Customer Support

ManageEngine offers strong support for OpManager users, with 24/5 technical assistance available via phone and email. They provide toll-free regional numbers (e.g., US, UK, Australia) and an international line for global access. Email support is handled promptly during business hours. For those needing more urgent or high-touch help, Premium Support plans are available, offering 24/7 emergency access and potentially a dedicated account manager. Their transparency with product roadmaps and release notes also helps businesses stay informed on upcoming fixes and features.

Beyond direct support, ManageEngine maintains an extensive self-service hub.
