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

"Without FortiManager, you cannot manage a complex environment across several sites with multiple firewalls."
"The best feature of Fortinet FortiManager is its ease of use. It is easy to manage the firewall from Fortinet FortiManager. Additionally, the interface is very good."
"It is stable."
"The most valuable feature is the centralized management console."
"The solution brings device management into one single pane of glass and is a pretty good product."
"It can scale well."
"It's very easy to install, and it's easy to discover and communicate with your device."
"It would normally take us a handful of days to install one FortiGate instance on one site. But with this technology, zero-touch deployment, we need just one hour or maybe as little as 30 minutes to install one site. It is much more efficient."
"Overall, the tool helps maintain the health of the network."
"It's quite a mature solution."
"If you install one node on Network Node Manager and want to scale it up, it's pretty easy to create more nodes."
"You can utilize the main file from various vendors for integration."
"The platform has good stability."
"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."
"The best feature is the solution's entire credibility with all vendors."
 

Cons

"Issues arise when customers experience unstable electricity or poor grounding conditions."
"The response times from technical support need to be a bit quicker."
"When I installed it, I found it somewhat difficult to set up."
"Fortinet FortiManager could improve them by adding more portfolio components."
"The SD-WAN solution is difficult to manage on FortiManager because you need to share some configurations on the firewall side. Sometimes you lose all connectivity with the firewall, so it is challenging to apply the default configuration to the SD-WAN solution."
"Wizards could be improved in pushing policies."
"The presence of Fortinet in our region (Nigeria) needs to be stronger."
"The price always has room for improvement."
"We have not had a good experience with technical support from OpenText. Many cases take a month to be resolved."
"The deployment architecture and installation part needs improvement."
"Only to improve the GUI."
"We had some issues with some of the features, some modules are not meeting expectations."
"They should add AI options in the product's next release."
"Micro Focus Network Node Manager is not powered to drill down for traffic visibility."
"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 way the solution currently works means I'm not able to customize my own reports."
 

Pricing and Cost Advice

"I hope that the prices will become more competitive in subsequent releases, as the current pricing is perceived as somewhat elevated."
"The pricing is based on a licensing model by feature."
"The license model they use depends on the size and is not limited to the users."
"Fortinet FortiManager can be expensive."
"This is an affordable solution, and its licensing model is based on the number of devices."
"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."
"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."
"FortiManager is reasonably priced - I pay around US$40,0000 per year, which covers fifty locations."
"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."
"It's an expensive solution."
"The solution is priced mid-range compared to the competition."
