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

"Central management system for Fortinet devices that's simple, scalable, and stable, with a straightforward setup."
"Fortinet has the option of synchronization in the cloud, so you can manage everything if you have a cloud account."
"Technical support was excellent."
"Fortinet FortiManager allows you to manage multiple FortiGate devices from a single console, and this is a valuable product feature."
"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."
"Setup, setting policies, and reporting were all very easy. We had no issues whatsoever getting the solution up and running."
"The initial setup of Fortinet FortiManager was easy."
"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 Network Manager has improved incident tracking and speed of response to trouble tickets."
"The platform has good stability."
"It is a good network monitoring, enterprise solution, and a meta-monitoring solution with good visualization."
"So actually it makes our life a lot easier in identifying if you've got problematic areas."
"Topology creation is the most valuable feature."
"It is stable for fault and availability."
"It has gradually evolved over time from a long initial stage to now where it's a very high scale product."
"It's a good one."
 

Cons

"The pricing and support could be improved."
"The GUI and the whole process of configuration should be improved."
"Wizards could be improved in pushing policies."
"It would be nice to have a virtual appliance as well."
"There are a lot of bugs that need to be fixed, for example, the ZTP."
"The presence of Fortinet in our region (Nigeria) needs to be stronger."
"The solution should be more open to other products."
"The user interface can feel clunky, especially for more complex tasks such as managing large-scale policy packages or custom scripts."
"We had some issues with some of the features, some modules are not meeting expectations."
"Sometimes technical support is not so amazing. We need to wait a long time to get a solution for a ticket."
"The way the solution currently works means I'm not able to customize my own reports."
"We are very dissatisfied with the technical support. We have multiple demands and even the engineers are not satisfied."
"Only to improve the GUI."
"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."
"I haven't had a great experience with this solution because the dashboards are not customizable and it's not user-friendly."
"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."
 

Pricing and Cost Advice

"This is an affordable solution, and its licensing model is based on the number of devices."
"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. However, for a large-scale environment with a lot of customers we have found it to be a worthwhile investment."
"Pricing could improve a little bit so I rate it a seven out of ten."
"Fortinet FortiManager operates on a licensing system that is dependent on the number of devices being managed. Yearly subscription renewal is necessary to continue using the service. Although there is a cost associated with Fortinet FortiManager, its price is undoubtedly justified by the value it provides in terms of the purpose it serves."
