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.

Performanc Monitoring and Application Architect at Hewlett Packard Enterprise
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 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 reports feature is excellent."
"I appreciate the ability to connect via SSH through Fortinet FortiManager to the FortiGates I manage. This feature allows me to gather information about the interfaces without having to physically connect to the device. This is a convenient aspect that I find valuable."
"It is easy to manage a huge number of devices with FortiManager."
"FortiManager's best feature is the integration of administrator users."
"Central management system for Fortinet devices that's simple, scalable, and stable, with a straightforward setup."

"A complete solution for network monitoring."
"I would recommend the solution to others due to the fact that it's quite stable and mature."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
"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."
"The platform has good stability."
"It gives us a good overview of what's happening in our networks and the devices in the networks."
"So actually it makes our life a lot easier in identifying if you've got problematic areas."

Cons

"We have experienced a series of minor bugs that necessitated contacting technical support on several occasions."
"Fortinet develops many different solutions but only some of them can be managed using FortiManager."
"It requires a lot of resources. This is the main challenge."
"The scalability has room for improvement."
"One of the biggest limitations is the grammar of the API – not the API itself."
"The solution could improve by having better integration with other solutions other than Fortinet."
"The CLI could be enhanced."
"The documentation could be better."
"The deployment architecture and installation part needs improvement."
"The technical documentation takes experience and much reading to master."
"They should add AI options in the product's next release."
"The setup was complex and needs a medium kind of knowledge. The documentation is also not very good, i.e., a lot of things that are not written in the document are surprises."
"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."
"Configuration was a bit cumbersome for SNMP traps on the routers and configuration of the SPIs was a little complicated."
"We have not had a good experience with technical support from OpenText. Many cases take a month to be resolved."
"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."
 

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."
"The price of Fortinet FortiManager is inexpensive."
"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."

"FortiManager is reasonably priced - I pay around US$40,0000 per year, which covers fifty locations."

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."
