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.

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"It is easy to manage a huge number of devices with FortiManager."
"The solution brings device management into one single pane of glass and is a pretty good product."
"The centralized management of policies and certificates, coupled with the capability to handle multi-site deployments effectively, provides streamlined operations."
"The user interface, along with user-friendly planning features, makes it straightforward to configure desired settings."
"It is easy to deploy to licenses."
"The setup is very simple."
"Centralized configuration is the most helpful feature. I like the ability to create templates and push them to all the devices at the same time. I also like that I can see the the logs with one device to provide zero touch on all other products."
"FortiManager's most valuable features are web-based or web-rule-based policies, SD-WAN, and the ease of upgrading to new firmware."
"The platform has good stability."
"If you install one node on Network Node Manager and want to scale it up, it's pretty easy to create more nodes."
"Our monitoring and network teams of less than 100 people use this solution. The availability and fault monitoring are good."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
"We do not have any issues stability-wise."
"It gives us a good overview of what's happening in our networks and the devices in the networks."
"It's quite a mature solution."
"Topology creation is the most valuable feature."
 

Cons

"The deployment of Fortinet FortiManager is quite complex and should be easier. It requires improvement in vulnerability management and should integrate automated AI features to enhance its reliability."
"The information extraction through command lines was could improve to some extent. Although there were some command lines available, there were not enough options. For instance, I needed to obtain the management IP address of my two Fortigates, but the Fortinet FortiManager did not provide me with the IP address on the LAN interface. I attempted to find this information through the command line but was unsuccessful. I also searched for articles on the internet, but could not find a solution. This is an aspect that could be improved or potentially there is a method to access this information that I have yet to discover."
"The FortiManager is more complex and they can make it easier to use the VPN manager. All other features are okay. However, the VPN manager is more difficult and can cause some issues in the environment, if you do not have the experience to use it."
"There are a lot of bugs that need to be fixed, for example, the ZTP."
"It requires a lot of resources. This is the main challenge."
"Issues arise when customers experience unstable electricity or poor grounding conditions."
"The product is not very stable."
"When I started, it was a bit difficult, however, now it's okay. It can be a bit complex for basic users."
"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."
"Reporting. Even though this is available in separate software (iSPI) there is potential in making the reporting more SLA-aware and more intuitive."
"The dashboards are not customizable and it's not user-friendly."
"The resources utilized could be a bit higher, and that is one of the challenges that isn't optimized"
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
"They should add AI options in the product's next release."
"The deployment architecture and installation part needs improvement."
"We had some issues with some of the features, some modules are not meeting expectations."

"The pricing model is affordable."
"The price of Fortinet FortiManager is inexpensive."
"Fortinet FortiManager is a low-priced product."
"Our organization pays a monthly license fee for the solution."

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."

"The solution is priced mid-range compared to the competition."
