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

"It's a very rich, robust product."
"FortiManager helps automate configuration deployment, allowing us to plan and schedule configurations."
"The most valuable feature is the central configuration for firewall policies."
"We like the central management capabilities."
"The most valuable features of Fortinet FortiManager, in my opinion, are SD-WAN and the manageability console."
"I find Fortinet's technical support for FortiManager effective and I would rate it eight out of ten."
"The most valuable feature of Fortinet FortiManager is the ease of manageability and policy-pushing functionality."
"This solution enables you to centralize the rules and the configuration of all the equipment."
"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."
"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."
"The Network Manager has improved incident tracking and speed of response to trouble tickets."
"Overall, the tool helps maintain the health of the network."
"It's quite a mature solution."
"It provides very good scalability from 200 nodes to 30,000 nodes and from 2,500 interfaces to 60,000 interfaces."
"It is a scalable product."
 

Cons

"You cannot integrate with other solutions, so they should allow integration with Cisco and Juniper."
"Troubleshooting for Fortinet products is more difficult than competing products like Cisco and Palo Alto."
"The solution should be more open to other products."
"The compatibility with legacy products should be better. It would also be nice if the software could manage other devices from Fortinet and third parties."
"Issues arise when customers experience unstable electricity or poor grounding conditions."
"FortiManager could improve by making it easier to port larger policy packages to the FortiGate firewalls. Sometimes, there's an issue when we install a big package of policies. If you have a couple thousand policies for FortiGate firewalls, it can take a few minutes to receive a response from the remote devices. It's only an issue when you're dealing with thousands of policies and installing them on a large number of devices."
"The solution has some bugs."
"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."
"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."
"We are very dissatisfied with the technical support. We have multiple demands and even the engineers are not satisfied."
"The way the solution currently works means I'm not able to customize my own reports."
"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."
"The solution should integrate with NAC servers."
"It needs better management for the routing protocol, which right now is really not very good."
"Only to improve the GUI."
"Sometimes technical support is not so amazing. We need to wait a long time to get a solution for a ticket."
 

Pricing and Cost Advice

"Pricing could improve a little bit so I rate it a seven out of ten."
"In comparison with other products, the price of FortiManager is reasonable."
"This is an affordable solution, and its licensing model is based on the number of devices."
"The pricing model is affordable."
"Fortinet FortiManager is not expensive at all if you compare it with other vendors like Check Point and Cisco. Fortinet products are the least expensive on the market in the category of firewalls."
"For the licensing fee, we paid around 10,000 to 15,000 euros."
"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."
"It's an expensive solution."
"The solution is priced mid-range compared to the competition."
"It is more inexpensive than other products in the market."
"I wasn't involved in the pricing, but I think it's quite expensive."
"The solution is quite expensive."
