SudeepMaydeo - PeerSpot reviewer
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."
"Fortinet has the option of synchronization in the cloud, so you can manage everything if you have a cloud account."
"The solution is very stable."
"The firmware version upgrades are the most valuable feature."
"It is a stable, reliable product."
"FortiManager's most valuable feature is central management."
"We like the central management capabilities."
"For the ROI, for a five-year project, Fortinet FortiManager would be the best option to use."
"The best feature is the solution's entire credibility with all vendors."
"So actually it makes our life a lot easier in identifying if you've got problematic areas."
"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."
"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."
"We do not have any issues stability-wise."
"If you install one node on Network Node Manager and want to scale it up, it's pretty easy to create more nodes."
 

Cons

"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."
"The solution has some bugs."
"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."
"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."
"Having FortiManager work with all of the Fortinet products would be a good improvement."
"There are a lot of bugs that need to be fixed, for example, the ZTP."
"The graphical user interface could use improvement as it appears complex and not user-friendly."
"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."
"Right now, we have open tickets and they are not closing as expected."
"The main issue with OpenText Network Node Manager is not its scalability but its network topology capability limitations, while installation and deployment types are supported across various platforms."
"It needs better management for the routing protocol, which right now is really not very good."
"We had some issues with some of the features, some modules are not meeting expectations."
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
"The cost is high comparing to its competitors, but the results are awesome."
"Sometimes technical support is not so amazing. We need to wait a long time to get a solution for a ticket."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
 

Pricing and Cost Advice

"On a scale from one to ten with one being the highest price and ten being the lowest price, I would rate FortiManager's price at three."
"The license model they use depends on the size and is not limited to the users."
"The price of Fortinet FortiManager is inexpensive."
"Pricing could improve a little bit so I rate it a seven out of ten."
"The pricing model is affordable."
"I hope that the prices will become more competitive in subsequent releases, as the current pricing is perceived as somewhat elevated."
"The pricing is based on a licensing model by feature."
"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."
"The solution is quite expensive."
"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."
"It's an expensive solution."
