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

"I like the rapid deployment feature. I also like that it's easy to troubleshoot. FortiManager is amazing because we can have a centralized policy. All our devices are integrated, and we can also engage in troubleshooting. We can use it for different deployments. One fantastic feature is the ability to create a version and deploy it immediately."
"Fortinet FortiManager allows you to manage multiple FortiGate devices from a single console, and this is a valuable product feature."
"It's very easy to install, and it's easy to discover and communicate with your device."
"Fortinet FortiManager's best features allow me to operate multiple devices in one template, which helps me in my daily work as it reduces time and has positively impacted my organization by making it easy to centrally access and manage around 15 FortiGate devices from one portal instead of accessing every device standalone."
"The centralized management of policies and certificates, coupled with the capability to handle multi-site deployments effectively, provides streamlined operations."
"The main benefit I receive from Fortinet FortiManager is that it streamlines every device."
"Fortinet FortiManager is effective and helpful for VPN management, such as deployment VPN management."
"The most valuable feature is the centralized management console."
"Effectively monitor networks physical and virtual devices."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
"The solution is very stable, and once it's configured properly, stability and maintenance are strong with no issues in performance."
"The Network Manager has improved incident tracking and speed of response to trouble tickets."
"I would recommend the solution to others due to the fact that it's quite stable and mature."
"So actually it makes our life a lot easier in identifying if you've got problematic areas."
"Overall, the tool helps maintain the health of the network."
"It is stable for fault and availability."
 

Cons

"Setting up FortiManager can be complex because it involves changes from other devices and a lot of configuration."
"There is a degradation of performance if we activate logs on FortiManager."
"Wizards could be improved in pushing policies."
"It would be nice to have a virtual appliance as well."
"The information extraction through command lines was could improve to some extent. Although there were some command lines available, there were not enough options. For instance, I needed to obtain the management IP address of my two Fortigates, but the Fortinet FortiManager did not provide me with the IP address on the LAN interface. I attempted to find this information through the command line but was unsuccessful. I also searched for articles on the internet, but could not find a solution. This is an aspect that could be improved or potentially there is a method to access this information that I have yet to discover."
"The fabric for integrations or connections could be improved."
"Its licensing model should be improved."
"The solution could improve by having better integration with other solutions other than Fortinet."
"Only to improve the GUI."
"The technical documentation takes experience and much reading to master."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
"I want to have some of those nicer features for when networks go flapping. I want to receive alerts before problems occur rather than when it actually goes down."
"That is a little bit difficult for me because I haven't been personally dealing with the software directly, so the subcontractor has been the face in informing us what the product is capable of."
"As the technologies evolve, also these solutions or the monitoring tools should evolve to cover the progress in technology, including capabilities related to monitoring of virtualized devices today, as the DNS is on the table in this way."
"I would say that they definitely need to improve their support features — this is a problem. When I open a ticket, usually they respond very late."
"Right now, we have open tickets and they are not closing as expected."
