SudeepMaydeo - PeerSpot reviewer
Global Head of IT Infrastructure at EPL Americas
Ensures seamless integration and centralized visibility for network security operations
The version upgrade from a single dashboard for all the firewalls in one click is the beauty of Fortinet FortiManager as the most impactful feature in managing our network security. Fortinet FortiManager's policy management enhances our security protocols by enabling us and giving integrated centralized visibility, which has proven to be very healthy. Because of this, we have identified some of the vulnerabilities in our systems, and we mitigated them through Fortinet FortiManager. The central dashboards and the visibility are what appealed to us to go with Fortinet FortiManager. Fortinet FortiManager has adapted to changes in our network scale and complexity as we have geographically 18 international locations, all equipped with firewalls and some cybersecurity initiatives and IT infrastructure initiatives.

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.

Pros

"It's a scalable product."
"It is easy to deploy to licenses."

"Stability is good within the product."
"The main benefit of Fortinet FortiManager is the ability to control all the devices from a central location, view their statuses, and manage their configurations and updates from a single management console."
"The most valuable features are the centralized management of the firewalls, by unifying the deployment process of the policies among many of the firewalls or virtual domains that you have, and it is very easy to install and use."
"The centralized management of policies and certificates, coupled with the capability to handle multi-site deployments effectively, provides streamlined operations."
"The most valuable features of Fortinet FortiManager, in my opinion, are SD-WAN and the manageability console."

Cons

"It's a difficult process to transfer one interface from one virtual domain to another."
"FortiManager could be more user-friendly."
"Fortinet is releasing quite a lot of new versions and I would say that most of the versions are not well tested before they're pushed out. Even the new versions sometimes are a bit buggy before it's all correct."
"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."
"Within the management of some features on FortiManager, specifically the management of user objects used for VPN service, FortiManager is quite weak."
"The price always has room for improvement."
"The GUI is not ideal."
"The solution has some bugs."
"The way the solution currently works means I'm not able to customize my own reports."
"Micro Focus Network Node Manager is not powered to drill down for traffic visibility."
"The deployment architecture and installation part needs improvement."
"Right now, we have open tickets and they are not closing as expected."
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
"They should add AI options in the product's next release."
"Customer service is not good compared to IBM or Zenoss support."
"Technical support could be much better and work much faster. Typically, it is taking some time to solve tickets."

"In comparison with other products, the price of FortiManager is reasonable."
"I hope that the prices will become more competitive in subsequent releases, as the current pricing is perceived as somewhat elevated."

"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a six out of ten."
"Fortinet is a high-end product and the cost is high. They should consider reducing the price, especially for existing customers."
