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

"There is something called zero-touch provisioning, where you can add a new device without any configuration. You just add it to FortiManager and then forget about it."
"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."
"It is easy to set up the solution."
"It makes management very easy."
"The most valuable feature of Fortinet FortiManager is the ease of manageability and policy-pushing functionality."
"The solution has the best stability for application control and inspections."
"I like the features on offer, for example SD-WAN; it's one single configuration point for everything, especially when you have a headquarters and branch, and the VPN is also beneficial, with very good correlation between FortiAnalyzer and FortiManager, and we find the pricing to be fair."
"Fortinet has the option of synchronization in the cloud, so you can manage everything if you have a cloud account."
"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 most important benefit is to have one controller and to get all information to a single point."
"The platform has good stability."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
"It's a good one."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
"Because of the topological network mapping, our management can quickly take action when there's a network problem."
"So actually it makes our life a lot easier in identifying if you've got problematic areas."
 

Cons

"Performance issues should be improved. We have problems when we have more mobile connections than local devices. Most of us have two to three devices."
"I prefer configuring rules and the VPN on the standalone device, not on the manager."
"The reporting details have room for 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."
"When we have a specific configuration pushed it does take some time to be deployed on the actual firewall."
"Regional support in African countries needs to be improved."
"There may be a communication issue. However, other items may be the culprit, such as network connectivity. It depends on the customer's network."
"I didn't like the connectivity with FortiManager and FortiSwitch, which was buggy and annoying and had fewer features."
"I want to have some of those nicer features for when networks go flapping. I want to receive alerts before problems occur rather than when it actually goes down."
"Customer service is not good compared to IBM or Zenoss support."
"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."
"I haven't had a great experience with this solution because the dashboards are not customizable and it's not user-friendly."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
"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."
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
 

Pricing and Cost Advice

"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."
"FortiManager is reasonably priced - I pay around US$40,0000 per year, which covers fifty locations."
"The pricing model is affordable."
"Fortinet is a high-end product and the cost is high. They should consider reducing the price, especially for existing customers."
"The license model they use depends on the size and is not limited to the users."
"Fortinet FortiManager operates on a licensing system that is dependent on the number of devices being managed. Yearly subscription renewal is necessary to continue using the service. Although there is a cost associated with Fortinet FortiManager, its price is undoubtedly justified by the value it provides in terms of the purpose it serves."
"I hope that the prices will become more competitive in subsequent releases, as the current pricing is perceived as somewhat elevated."
"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."
"It's an expensive solution."
"The solution is priced mid-range compared to the competition."
"I wasn't involved in the pricing, but I think it's quite expensive."
"The solution is quite expensive."
"It is more inexpensive than other products in the market."
