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 most valuable features of Fortinet FortiManager are the overall management it provides and its ease of use."
"Central management system for Fortinet devices that's simple, scalable, and stable, with a straightforward setup."
"The capability of centralized management is valuable, and we can configure all firewall boxes with the same configuration."
"Fortinet FortiManager's best features allow me to operate multiple devices in one template, which helps me in my daily work as it reduces time and has positively impacted my organization by making it easy to centrally access and manage around 15 FortiGate devices from one portal instead of accessing every device standalone."
"Fortinet FortiManager allows a full view of all the devices on the network from one location."
"It's very easy to install, and it's easy to discover and communicate with your device."
"The technical support for us is great."
"FortiManager's most valuable feature is central management."
"Scalability is actually one of the reasons why we picked Node Manager."
"A complete solution for network monitoring."
"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."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
"It gives us a good overview of what's happening in our networks and the devices in the networks."
"You can utilize the main file from various vendors for integration."
"We do not have any issues stability-wise."
 

Cons

"It requires a lot of resources. This is the main challenge."
"The GUI could be updated. It's not as good as it could be and is something the solution should improve in an upcoming release."
"There may be a communication issue. However, other items may be the culprit, such as network connectivity. It depends on the customer's network."
"My rating is not perfect due to the threat intelligence of Fortinet FortiManager, which has a lot of false positives."
"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."
"Areas for improvement in Fortinet FortiManager are scalability and stability."
"In the next release, FortiManager should include more protection features."
"The documentation could be better."
"The deployment architecture and installation part needs improvement."
"They should add AI options in the product's next release."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
"Only to improve the GUI."
"We are very dissatisfied with the technical support. We have multiple demands and even the engineers are not satisfied."
"It needs better management for the routing protocol, which right now is really not very good."
"The way the solution currently works means I'm not able to customize my own reports."
"Customer service is not good compared to IBM or Zenoss support."
 

Pricing and Cost Advice

"I hope that the prices will become more competitive in subsequent releases, as the current pricing is perceived as somewhat elevated."
"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."
"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."
"For the licensing fee, we paid around 10,000 to 15,000 euros."
"FortiManager is a bit expensive - I would rate its pricing three out of ten."
"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."
"Pricing could improve a little bit so I rate it a seven out of ten."
"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."
"The solution is quite expensive."
"It's an expensive solution."
"It is more inexpensive than other products in the market."
"The solution is priced mid-range compared to the competition."
"I wasn't involved in the pricing, but I think it's quite expensive."
