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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Fortinet FortiManager is effective and helpful for VPN management, such as deployment VPN management."
"FortiManager enables us to set unified firewall policies from one centralized dashboard, reducing human error. If you do not have a central dashboard, there's a chance you might set a policy on one firewall and forget to do it for another."
"It's a scalable product."
"The central management feature is the most valuable to me."
"The product is a combination of management and monitoring from the same interface."
"Technical support is great. When we have sent urgent tickets and they do reply back within fifteen minutes."
"The firmware version upgrades are the most valuable feature."
"Centralized configuration is the most helpful feature. I like the ability to create templates and push them to all the devices at the same time. I also like that I can see the the logs with one device to provide zero touch on all other products."
"It's quite a mature solution."
"It gives us a good overview of what's happening in our networks and the devices in the networks."
"Most valuable function would have to the internal causal engine and its root cause analyzer which keep us updated on critical errors and incidents in our network environment."
"Topology creation is the most valuable feature."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
"The best feature is the solution's entire credibility with all vendors."
"A good enterprise-level solution."
"You can utilize the main file from various vendors for integration."
 

Cons

"Fortinet FortiManager could improve them by adding more portfolio components."
"When I started, it was a bit difficult, however, now it's okay. It can be a bit complex for basic users."
"It requires a lot of resources. This is the main challenge."
"I didn't like the connectivity with FortiManager and FortiSwitch, which was buggy and annoying and had fewer features."

"The scalability has room for improvement."
"We had some issues with some of the features, some modules are not meeting expectations."
"Right now, we have open tickets and they are not closing as expected."
"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."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
"The dashboards are not customizable and it's not user-friendly."
"The way the solution currently works means I'm not able to customize my own reports."

"Compared to Check Point or Cisco, Fortinet FortiManager is more affordable but it is still on the higher end."
