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.

"It is easy to deploy to licenses."
"Without FortiManager, you cannot manage a complex environment across several sites with multiple firewalls."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."

"The solution is very stable, and once it's configured properly, stability and maintenance are strong with no issues in performance."
"It has gradually evolved over time from a long initial stage to now where it's a very high scale product."
"We need fault, availability, performance, and security."
"It is a good network monitoring, enterprise solution, and a meta-monitoring solution with good visualization."

Cons

"Wizards could be improved in pushing policies."
"The solution has some bugs."
"It requires a lot of resources. This is the main challenge."
"It would be nice to have a virtual appliance as well."
"For the IPSEC tunnels, Fortimanager doesn't have all of the features that are available on Fortigate."
"The scalability has room for improvement."
"This solution needs more experienced technical support staff."
"Fortinet is releasing quite a lot of new versions and I would say that most of the versions are not well tested before they're pushed out. Even the new versions sometimes are a bit buggy before it's all correct."
"The resources utilized could be a bit higher, and that is one of the challenges that isn't optimized"
"It needs better management for the routing protocol, which right now is really not very good."
"As the technologies evolve, also these solutions or the monitoring tools should evolve to cover the progress in technology, including capabilities related to monitoring of virtualized devices today, as the DNS is on the table in this way."
"In terms of improvement, I would say that the resources utilized could be a bit higher, and that is one of the challenges that isn't optimized to my expectations."
"As the technologies evolve, also these solutions or the monitoring tools should evolve to cover the progress in technology, including capabilities related to monitoring of virtualized devices today, as the DNS is on the table in this way."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
"Sometimes technical support is not so amazing. We need to wait a long time to get a solution for a ticket."
"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."
 

Pricing and Cost Advice

"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."
