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

"The most valuable features of Fortinet FortiManager, in my opinion, are SD-WAN and the manageability console."
"I like the features on offer, for example SD-WAN; it's one single configuration point for everything, especially when you have a headquarters and branch, and the VPN is also beneficial, with very good correlation between FortiAnalyzer and FortiManager, and we find the pricing to be fair."
"The centralized policy management helps with the creation of policies because it is easy to monitor and facilitates installation."
"We are managing a research and education network, and we have about 200 Fortinet FortiGate devices dispatched in the country, and we are managing all of them with FortiManager, which has simplified the management and reduced the time to configure the devices."
"The features are good."
"Provides good and detailed log management."
"The technical support for us is great."
"FortiManager is the best suite for SMBs."
"It gives us a good overview of what's happening in our networks and the devices in the networks."
"Because of the topological network mapping, our management can quickly take action when there's a network problem."
"I would recommend the solution to others due to the fact that it's quite stable and mature."
"The Network Manager has improved incident tracking and speed of response to trouble tickets."
"The great thing about this solution is its compatibility for enterprise level organizations; if you need to install 10,000 or even 20,000 devices, it's easy to monitor, and the product's fault management is awesome."
"The most important benefit is to have one controller and to get all information to a single point."
"It is stable for fault and availability."
"Effectively monitor networks physical and virtual devices."
 

Cons

"The user interface can feel clunky, especially for more complex tasks such as managing large-scale policy packages or custom scripts."
"The SD-WAN solution is difficult to manage on FortiManager because you need to share some configurations on the firewall side. Sometimes you lose all connectivity with the firewall, so it is challenging to apply the default configuration to the SD-WAN solution."
"The solution has some bugs."
"The solution should be more open to other products."
"Setting up FortiManager can be complex because it involves changes from other devices and a lot of configuration."
"Can be difficult to configure."
"Configuring Fortinet without internet access is challenging."
"I think the initial setup is too complicated because there are several versions of the operating systems, so you don't have directly connections between two devices."
"Only to improve the GUI."
"The technical documentation takes experience and much reading to master."
"The deployment architecture and installation part needs improvement."
"The way the solution currently works means I'm not able to customize my own reports."
"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."
"Micro Focus Network Node Manager is not powered to drill down for traffic visibility."
"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."
"The cost is high comparing to its competitors, but the results are awesome."
