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

"It can scale well."
"The solution's most valuable feature is the consolidation and the single point of administration solution."
"FortiManager offers a full zero-touch provisioning feature that allows us to create a template of our devices and onboard them remotely without visiting the site."
"This solution enables you to centralize the rules and the configuration of all the equipment."
"It would normally take us a handful of days to install one FortiGate instance on one site, but with this technology, zero-touch deployment, we need just one hour or maybe as little as 30 minutes to install one site."
"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."
"A fully integrated solution."
"You can configure it at your ease."
"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."
"So actually it makes our life a lot easier in identifying if you've got problematic areas."
"Our monitoring and network teams of less than 100 people use this solution. The availability and fault monitoring are good."
"Topology creation is the most valuable feature."
"Because of the topological network mapping, our management can quickly take action when there's a network problem."
"It is a scalable product."
"It provides very good scalability from 200 nodes to 30,000 nodes and from 2,500 interfaces to 60,000 interfaces."
"It is a good network monitoring, enterprise solution, and a meta-monitoring solution with good visualization."
 

Cons

"Their EDR products could be better. They need to dedicate more R&D to that area."
"The price is a bit too high."
"One of the biggest limitations is the grammar of the API – not the API itself."
"There are a lot of bugs that need to be fixed, for example, the ZTP."
"The solution has to be enhanced to manage new switches."
"It would be nice to have a virtual appliance as well."
"The scalability has room for improvement."
"FortiManager would be improved by putting everything into a single console, including Microsoft O365 integration."
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
"I haven't had a great experience with this solution because the dashboards are not customizable and it's not user-friendly."
"Only to improve the GUI."
"It needs better management for the routing protocol, which right now is really not very good."
"Sometimes technical support is not so amazing. We need to wait a long time to get a solution for a ticket."
"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 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."
"We have not had a good experience with technical support from OpenText. Many cases take a month to be resolved."
 

Pricing and Cost Advice

"The price point is very good."
"The pricing is based on a licensing model by feature."
"Fortinet FortiManager is a low-priced product."
"Fortinet FortiManager can be expensive."
"Our organization pays a monthly license fee for the solution."
"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."
"It's an expensive solution."
"I wasn't involved in the pricing, but I think it's quite expensive."
"It is more inexpensive than other products in the market."
