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.

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

"We look at the traffic to segment the network and it improves and increases the performance. When we have a mobile connection and local laptops are on the same network. We have seen a big performance upgrade."
"Even without the security orchestration, just the fact that the customer could request the firewall team to configure a job that would roll out a configuration on the firewalls and it could be deployed across all the firewalls through the FortiManager was a big improvement compared to deploying the new firewall rule on each firewall sequentially."
"FortiManager's best feature is the integration of administrator users."
"I appreciate the ability to connect via SSH through Fortinet FortiManager to the FortiGates I manage. This feature allows me to gather information about the interfaces without having to physically connect to the device. This is a convenient aspect that I find valuable."
"Fortinet has the option of synchronization in the cloud, so you can manage everything if you have a cloud account."
"Fortinet FortiManager is effective and helpful for VPN management, such as deployment VPN management."
"The product is a combination of management and monitoring from the same interface."
"It's a scalable product."
"If you install one node on Network Node Manager and want to scale it up, it's pretty easy to create more nodes."
"A good enterprise-level solution."
"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."
"Because of the topological network mapping, our management can quickly take action when there's a network problem."
"The HPE suite is amazingly beautiful, has a fantastic user experience, and provides a high amount of simplification across transactions when adopting cloud technologies significantly."
"The Network Manager has improved incident tracking and speed of response to trouble tickets."
"So actually it makes our life a lot easier in identifying if you've got problematic areas."
"It gives us a good overview of what's happening in our networks and the devices in the networks."
 

Cons

"Having FortiManager work with all of the Fortinet products would be a good improvement."
"The compatibility with legacy products should be better. It would also be nice if the software could manage other devices from Fortinet and third parties."
"I think Fortinet FortiManager can be improved as the web page loading is slightly slow."
"In the next release, FortiManager should include more protection features."
"I put seven for scalability because it is a bit complex to add some new devices and new users, or that function could be simplified."
"You cannot integrate with other solutions, so they should allow integration with Cisco and Juniper."
"When we have a specific configuration pushed it does take some time to be deployed on the actual firewall."
"I would like to be able to manage other products such as Endpoint and FortiAnalyzer through FortiManager. That is, the integration with other solutions needs to be improved."
"Right now, we have open tickets and they are not closing as expected."
"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."
"Technical support could be much better and work much faster. Typically, it is taking some time to solve tickets."
"Only to improve the GUI."
"It needs better management for the routing protocol, which right now is really not very good."
"We are very dissatisfied with the technical support. We have multiple demands and even the engineers are not satisfied."
"Reporting. Even though this is available in separate software (iSPI) there is potential in making the reporting more SLA-aware and more intuitive."
"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."
