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

"It can scale well."
"The most valuable feature is having one object on all networks, which allows for implementation only once."
"The integration is quite good."
"Central management system for Fortinet devices that's simple, scalable, and stable, with a straightforward setup."
"We like the central management capabilities."
"Everybody is quite happy with the way that the graphical user interface works."
"It's a very rich, robust product."
"It makes management very easy."
"Scalability is actually one of the reasons why we picked Node Manager."
"It is a good network monitoring, enterprise solution, and a meta-monitoring solution with good visualization."
"Our monitoring and network teams of less than 100 people use this solution, and the availability and fault monitoring are good."
"If you install one node on Network Node Manager and want to scale it up, it's pretty easy to create more nodes."
"It's quite a mature solution."
"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 Network Manager has improved incident tracking and speed of response to trouble tickets."
"It provides very good scalability from 200 nodes to 30,000 nodes and from 2,500 interfaces to 60,000 interfaces."
 

Cons

"Regional support in African countries needs to be improved."
"The product is not very stable."
"The solution has to be enhanced to manage new switches."
"The user interface itself has areas that need improvement."
"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 GUI is not ideal."
"The pricing and support could be improved."
"If you have more than one FortiMail device, you can't manage it then with FortiManager on FortiGate."
"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."
"They should add AI options in the product's next release."
"The technical documentation takes experience and much reading to master."
"Reporting. Even though this is available in separate software (iSPI) there is potential in making the reporting more SLA-aware and more intuitive."
"The way the solution currently works means I'm not able to customize my own reports."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
"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."
"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."
 

Pricing and Cost Advice

"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. However, for a large-scale environment with a lot of customers we have found it to be a worthwhile investment."
"Fortinet is a high-end product and the cost is high. They should consider reducing the price, especially for existing customers."
"Fortinet FortiManager can be expensive."
"FortiManager is reasonably priced - I pay around US$40,0000 per year, which covers fifty locations."
"FortiManager isn't expensive, but its cost is dependent on which services are required."
"Fortinet FortiManager is a low-priced product."
"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."
"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."
"The solution is priced mid-range compared to the competition."
"It's an expensive solution."
