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 is a stable, reliable product."
"The main benefit I receive from Fortinet FortiManager is that it streamlines every device."
"The solution's most valuable feature is the consolidation and the single point of administration solution."
"FortiManager's best feature is the integration of administrator users."
"Being able to push consistent firewall rules and configuration changes across multiple FortiGates saves a ton of time and reduces errors compared to managing each device individually."
"The most valuable feature is the centralized management console."
"It is easy to set up the solution."
"FortiManager's ability to scale is good."
"So actually it makes our life a lot easier in identifying if you've got problematic areas."
"We need fault, availability, performance, and security."
"The great thing about this solution is its compatibility for enterprise level organizations; if you need to install 10,000 or even 20,000 devices, it's easy to monitor, and the product's fault management is awesome."
"The Network Manager has improved incident tracking and speed of response to trouble tickets."
"I would recommend the solution to others due to the fact that it's quite stable and mature."
"If you install one node on Network Node Manager and want to scale it up, it's pretty easy to create more nodes."
"Because of the topological network mapping, our management can quickly take action when there's a network problem."
"It is a scalable product."
 

Cons

"The GUI and the whole process of configuration should be improved."
"I think the initial setup is too complicated because there are several versions of the operating systems, so you don't have directly connections between two devices."
"There may be a communication issue. However, other items may be the culprit, such as network connectivity. It depends on the customer's network."
"The product is not very stable."
"Issues arise when customers experience unstable electricity or poor grounding conditions."
"We have experienced a series of minor bugs that necessitated contacting technical support on several occasions."
"FortiManager needs to handle different firewall versions more efficiently."
"I didn't like the connectivity with FortiManager and FortiSwitch, which was buggy and annoying and had fewer features."
"The solution should integrate with NAC servers."
"Technical support could be much better and work much faster. Typically, it is taking some time to solve tickets."
"Configuration was a bit cumbersome for SNMP traps on the routers and configuration of the SPIs was a little complicated."
"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."
"It needs better management for the routing protocol, which right now is really not very good."
"Micro Focus Network Node Manager is not powered to drill down for traffic visibility."
"The cost is high comparing to its competitors, but the results are awesome."
"Right now, we have open tickets and they are not closing as expected."
 

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."
"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."
"FortiManager is reasonably priced - I pay around US$40,0000 per year, which covers fifty locations."
"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."
"For the licensing fee, we paid around 10,000 to 15,000 euros."
"The license model they use depends on the size and is not limited to the users."
