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

"FortiManager is a benefit to our clients who have several Fortinet products in their ecosystem."
"Everybody is quite happy with the way that the graphical user interface works."

"The most important benefit is to have one controller and to get all information to a single point."
 

Cons

"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."
"We have experienced a series of minor bugs that necessitated contacting technical support on several occasions."
"The GUI is not ideal. It needs to be improved. It should be more user-friendly."
"The solution requires you to have a license for every device, as well as for any advanced features being used, which makes it costly for high-volume users."
"FortiManager needs to handle different firewall versions more efficiently."
"The price always has room for improvement."
"Fortinet FortiManager could improve them by adding more portfolio components."
"The deployment of Fortinet FortiManager is quite complex and should be easier. It requires improvement in vulnerability management and should integrate automated AI features to enhance its reliability."
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
"Micro Focus Network Node Manager is not powered to drill down for traffic visibility."
"Customer service is not good compared to IBM or Zenoss support."
"We have not had a good experience with technical support from OpenText. Many cases take a month to be resolved."
"It is hindering us so much because we cannot give it directly to customers because after a number of connections, the system goes down within one minute."
"Right now, we have open tickets and they are not closing as expected."
"We are very dissatisfied with the technical support. We have multiple demands and even the engineers are not satisfied."
"The technical documentation takes experience and much reading to master."
