Manage multiple devices with ease but experience complexity in deployment and limited AI features
I use Fortinet FortiManager to manage multiple devices in a single location. Although it does not provide a security posture itself, it depends on the firewall policies and settings in their respective firewalls. Fortinet FortiManager is primarily meant for the management of devices Fortinet…

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and SLAs, and I can build compliance reports to address security vulnerabilities, such as identifying all devices using outdated protocols.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 central management feature is the most valuable to me."
"Central management system for Fortinet devices that's simple, scalable, and stable, with a straightforward setup."
"You can configure it at your ease."
"It can scale well."
"Without FortiManager, you cannot manage a complex environment across several sites with multiple firewalls."
"The firewall configuration has more capabilities than the other firewall management systems that I have worked with."
"The integration is quite good."
"It's very easy to install, and it's easy to discover and communicate with your device."
"You can utilize the main file from various vendors for integration."
"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."
"Overall, the tool helps maintain the health of the network."
"A good enterprise-level solution."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
"It's quite a mature solution."
"It is stable for fault and availability."
"If you install one node on Network Node Manager and want to scale it up, it's pretty easy to create more nodes."
 

Cons

"FortiManager would be improved by putting everything into a single console, including Microsoft O365 integration."
"Their EDR products could be better. They need to dedicate more R&D to that area."
"The GUI is not ideal."
"The price is a bit too high."
"Within the management of some features on FortiManager, specifically the management of user objects used for VPN service, FortiManager is quite weak."
"There may be a communication issue. However, other items may be the culprit, such as network connectivity. It depends on the customer's network."
"We have experienced a series of minor bugs that necessitated contacted technical support on several occasions."
"FortiManager could improve by making it easier to port larger policy packages to the FortiGate firewalls. Sometimes, there's an issue when we install a big package of policies. If you have a couple thousand policies for FortiGate firewalls, it can take a few minutes to receive a response from the remote devices. It's only an issue when you're dealing with thousands of policies and installing them on a large number of devices."
"Micro Focus Network Node Manager is not powered to drill down for traffic visibility."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
"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."
"Reporting. Even though this is available in separate software (iSPI) there is potential in making the reporting more SLA-aware and more intuitive."
"The resources utilized could be a bit higher, and that is one of the challenges that isn't optimized"
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
"The solution should integrate with NAC servers."
"We had some issues with some of the features, some modules are not meeting expectations."
 

Pricing and Cost Advice

"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a six out of ten."
"The pricing model is affordable."
"In comparison with other products, the price of FortiManager is reasonable."
"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 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."
"Fortinet FortiManager is a low-priced product."
"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."
"This is an affordable solution, and its licensing model is based on the number of devices."
"The solution is quite expensive."
"It's an expensive solution."
"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 priced mid-range compared to the competition."
