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 centralized management of policies and certificates, coupled with the capability to handle multi-site deployments effectively, provides streamlined operations."
"The solution is very stable."
"The features are good."
"I pushed templates from FortiManager to our site, and they were deployed successfully."
"The setup is very simple."
"The product is a combination of management and monitoring from the same interface."
"For the ROI, for a five-year project, Fortinet FortiManager would be the best option to use."
"FortiManager is for the syncing of devices, and when companies are using multiple devices from Fortinet, such as FortiGate, FortiSwitches, and FortiAP, it is required so that a single person can centrally manage all of the devices, making it a very useful application."
"The Network Manager has improved incident tracking and speed of response to trouble tickets."
"The platform has good stability."
"We do not have any issues stability-wise."
"The solution is very stable, and once it's configured properly, stability and maintenance are strong with no issues in performance."
"It is a scalable product."
"Overall, the tool helps maintain the health of the network."
"Most valuable function would have to the internal causal engine and its root cause analyzer which keep us updated on critical errors and incidents in our network environment."
"It gives us a good overview of what's happening in our networks and the devices in the networks."
 

Cons

"When I started, it was a bit difficult, however, now it's okay. It can be a bit complex for basic users."
"It would be better if it were easier to run a routing protocol. In the next release, I would like them to enhance some features in the GUI rather than CLI or OSP. For example, whenever a customer generates an ISP directly on the firewall, it's complicated to configure the routing protocol."
"It requires a lot of resources. This is the main challenge."
"Within the management of some features on FortiManager, specifically the management of user objects used for VPN service, FortiManager is quite weak."
"The price always has room for improvement."
"The solution has some bugs."
"The FortiManager is more complex and they can make it easier to use the VPN manager. All other features are okay. However, the VPN manager is more difficult and can cause some issues in the environment, if you do not have the experience to use it."
"We have experienced a series of minor bugs that necessitated contacting technical support on several occasions."
"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."
"The technical documentation takes experience and much reading to master."
"Customer service is not good compared to IBM or Zenoss support."
"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."
"Sometimes technical support is not so amazing. We need to wait a long time to get a solution for a ticket."
"The cost is high comparing to its competitors, but the results are awesome."
"Only to improve the GUI."
 

Pricing and Cost Advice

"For the licensing fee, we paid around 10,000 to 15,000 euros."
"The pricing model is affordable."
"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."
"The license model they use depends on the size and is not limited to the users."
"Our organization pays a monthly license fee for the solution."
"The licensing costs depend on how many devices you want to use."
"Fortinet is a high-end product and the cost is high. They should consider reducing the price, especially for existing customers."
"Fortinet FortiManager is a low-priced product."
"I wasn't involved in the pricing, but I think it's quite expensive."
"It is more inexpensive than other products in the market."
"The solution is priced mid-range compared to the competition."
"It's an expensive solution."
"The solution is quite expensive."
