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."
"In general, I have no serious concerns about this product so I have no problems recommending it."
"Technical support was excellent."
"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."
"If we use the Fortinet FortiManager to replicate the configuration and want to install ten FortiGate on ten sites, you don't have to set configuration on all ten because you can configure one FortiGate and the Fortinet FortiManager will replicate the configuration on all FortiGate devices."
"The solution has the best stability for application control and inspections."
"The best feature of Fortinet FortiManager is its ease of use. It is easy to manage the firewall from Fortinet FortiManager. Additionally, the interface is very good."
"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."
"We do not have any issues stability-wise."
"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."
"It gives us a good overview of what's happening in our networks and the devices in the networks."
"It's quite a mature solution."
"If you install one node on Network Node Manager and want to scale it up, it's pretty easy to create more nodes."
"Because of the topological network mapping, our management can quickly take action when there's a network problem."
"Topology creation is the most valuable feature."
"Our monitoring and network teams of less than 100 people use this solution, and the availability and fault monitoring are good."
 

Cons

"The GUI and the whole process of configuration should be improved."
"The scalability has room for improvement."
"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."
"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."
"We have experienced a series of minor bugs that necessitated contacting technical support on several occasions."
"The fabric for integrations or connections could be improved."
"There may be a communication issue. However, other items may be the culprit, such as network connectivity. It depends on the customer's network."
"It would be nice to have a virtual appliance as well."
"The deployment architecture and installation part needs improvement."
"Only to improve the GUI."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
"Right now, we have open tickets and they are not closing as expected."
"The way the solution currently works means I'm not able to customize my own reports."
"Sometimes technical support is not so amazing. We need to wait a long time to get a solution for a ticket."
"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."
"They should add AI options in the product's next release."
 

Pricing and Cost Advice

"FortiManager is reasonably priced - I pay around US$40,0000 per year, which covers fifty locations."
"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."
"The price of Fortinet FortiManager is inexpensive."
"Compared to Check Point or Cisco, Fortinet FortiManager is more affordable but it is still on the higher end."
"If you compare Fortinet and Palo Alto, Fortinet is cheaper, but if you compare Cisco and Fortinet, sometimes Cisco is cheaper because Cisco gives us more discounts because of the size. Cisco isn't cheap, but sometimes, we get a big discount from them."
"The pricing model is affordable."
"Pricing could improve a little bit so I rate it a seven out of ten."
"FortiManager isn't expensive, but its cost is dependent on which services are required."
"It's an expensive solution."
"It is more inexpensive than other products in the market."
