Manage multiple devices with ease but experience complexity in deployment and limited AI features
I use Fortinet FortiManager to manage multiple devices in a single location. Although it does not provide a security posture itself, it depends on the firewall policies and settings in their respective firewalls. Fortinet FortiManager is primarily meant for the management of devices Fortinet…

Reliable network monitoring and proactive analytics enhance decision-making with areas for configuration improvement
NNMi is an OpenText product and serves as the OpenText Network Node Manager monitoring tool. OpenText Network Node Manager is used for network monitoring of switches, routers, firewalls, load balancers, and all network devices. It can support any SNMP protocol. The advantages of OpenText Network Node Manager stand out because it can build the topology, Layer 2 topology, and Layer 3 automatically once devices are added, connecting them together, such as device one, for interface one, connected with interface one on another device. The integration capability of OpenText Network Node Manager is excellent because it integrates directly, and I can configure the integration to feed the CMDB, from where I can get all information from network monitoring into the CMDB, linking it with the infrastructure and correlating events. I use advanced fault monitoring and management features in OpenText Network Node Manager for topology and fault monitoring, as it can alert or generate an event if the value exceeds or falls below a predefined threshold for SNMP traps. The predictive analytics impact planning and optimization strategies because the product can be linked with another product for analytic analysis, allowing me to see the interface utilization trend and proactively take action if the utilization increases. The automated network discovery features and topology mapping in OpenText Network Node Manager have a positive impact. It supports a bundle with another product for NetFlow to monitor traffic, ports, protocols, and SLAs, and I can build compliance reports to address security vulnerabilities, such as identifying all devices using outdated protocols.

Quotes from Members

Pros

"It's a scalable product."

"FortiManager's most valuable feature is central management."
"FortiManager's most valuable features are web-based or web-rule-based policies, SD-WAN, and the ease of upgrading to new firmware."
"It has multiple features in one box, which helps to avoid needing a lot of equipment. This is something that makes them unique."
"It gives us a good overview of what's happening in our networks and the devices in the networks."
"We do not have any issues stability-wise."
"Our monitoring and network teams of less than 100 people use this solution. The availability and fault monitoring are good."
"The best feature is the solution's entire credibility with all vendors."
"Topology creation is the most valuable feature."
"A good enterprise-level solution."

Cons

"I would like to be able to manage other products such as Endpoint and FortiAnalyzer through FortiManager. That is, the integration with other solutions needs to be improved."
"The FortiManager is more complex and they can make it easier to use the VPN manager. All other features are okay. However, the VPN manager is more difficult and can cause some issues in the environment, if you do not have the experience to use it."
"The fabric for integrations or connections could be improved."
"The presence of Fortinet in our region (Nigeria) needs to be stronger."
"Can be difficult to configure."
"Regional support in African countries needs to be improved."
"Wizards could be improved in pushing policies."
"The areas that need improvement are implemenation and support. In terms of implementation, it mainly needs clear documentation."
"The deployment architecture and installation part needs improvement."
"The main issue with OpenText Network Node Manager is not its scalability but its network topology capability limitations, while installation and deployment types are supported across various platforms."
"Only to improve the GUI."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
"We have not had a good experience with technical support from OpenText. Many cases take a month to be resolved."
"Reporting. Even though this is available in separate software (iSPI) there is potential in making the reporting more SLA-aware and more intuitive."
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
"We had some issues with some of the features, some modules are not meeting expectations."

"Our organization pays a monthly license fee for the solution."

"Fortinet is a high-end product and the cost is high. They should consider reducing the price, especially for existing customers."
