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.

Pros

"It can scale well."
"The product is a combination of management and monitoring from the same interface."
"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."
"Without FortiManager, you cannot manage a complex environment across several sites with multiple firewalls."
"The SD-WAN deployment environment, and the SD-WAN templates are particularly useful. Managing the solution is very intuitive. The initial setup of the solution was very straightforward."
"The product is easy to use and manage."
"The solution brings device management into one single pane of glass and is a pretty good product."
"FortiManager's most valuable features are web-based or web-rule-based policies, SD-WAN, and the ease of upgrading to new firmware."
"It gives us a good overview of what's happening in our networks and the devices in the networks."
"The platform has good stability."
"Overall, the tool helps maintain the health of the network."
"You can utilize the main file from various vendors for integration."
"It is a scalable product."
"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."
"A good enterprise-level solution."
"It's quite a mature solution."
 

Cons

"The areas that need improvement are implemenation and support. In terms of implementation, it mainly needs clear documentation."
"The dashboard could use some improvement."
"When I installed it, I found it somewhat difficult to set up."
"It would be better if it were easier to run a routing protocol. In the next release, I would like them to enhance some features in the GUI rather than CLI or OSP. For example, whenever a customer generates an ISP directly on the firewall, it's complicated to configure the routing protocol."
"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."
"When I started, it was a bit difficult, however, now it's okay. It can be a bit complex for basic users."
"Regional support in African countries needs to be improved."
"Issues arise when customers experience unstable electricity or poor grounding conditions."
"Micro Focus Network Node Manager is not powered to drill down for traffic visibility."
"Reporting. Even though this is available in separate software (iSPI) there is potential in making the reporting more SLA-aware and more intuitive."
"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."
"The way the solution currently works means I'm not able to customize my own reports."
"We had some issues with some of the features, some modules are not meeting expectations."
"The solution should integrate with NAC servers."
"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."
"The resources utilized could be a bit higher, and that is one of the challenges that isn't optimized"
