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

"Everybody is quite happy with the way that the graphical user interface works."
"The centralized management of policies and certificates, coupled with the capability to handle multi-site deployments effectively, provides streamlined operations."
"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 most valuable feature of Fortinet FortiManager is the ease of manageability and policy-pushing functionality."
"I pushed templates from FortiManager to our site, and they were deployed successfully."
"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."
"It is easy to set up the solution."
"Without FortiManager, you cannot manage a complex environment across several sites with multiple firewalls."
"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."
"It is stable for fault and availability."
"Topology creation is the most valuable feature."
"It is a scalable product."
"It's quite a mature solution."
"Our monitoring and network teams of less than 100 people use this solution. The availability and fault monitoring are good."
"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."
 

Cons

"There is a degradation of performance if we activate logs on FortiManager."
"The solution could improve by having better integration with other solutions other than Fortinet."
"Setting up FortiManager can be complex because it involves changes from other devices and a lot of configuration."
"The price is a bit too high."
"FortiManager needs to handle different firewall versions more efficiently."
"If you have more than one FortiMail device, you can't manage it then with FortiManager on FortiGate."
"In future updates, I would like to see more customization and AI integration."
"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."
"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."
"Micro Focus Network Node Manager is not powered to drill down for traffic visibility."
"We have not had a good experience with technical support from OpenText. Many cases take a month to be resolved."
"They should add AI options in the product's next release."
"The deployment architecture and installation part needs improvement."
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
"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."
 

Pricing and Cost Advice

"For the licensing fee, we paid around 10,000 to 15,000 euros."
"The licensing costs depend on how many devices you want to use."
"Compared to Check Point or Cisco, Fortinet FortiManager is more affordable but it is still on the higher end."
"The price of Fortinet FortiManager is inexpensive."
"Fortinet FortiManager is costly."
"If you compare Fortinet and Palo Alto, Fortinet is cheaper, but if you compare Cisco and Fortinet, sometimes Cisco is cheaper because Cisco gives us more discounts because of the size. Cisco isn't cheap, but sometimes, we get a big discount from them."
"Fortinet is a high-end product and the cost is high. They should consider reducing the price, especially for existing customers."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a six out of ten."
"It is more inexpensive than other products in the market."
"It's an expensive solution."
"I wasn't involved in the pricing, but I think it's quite expensive."
"The solution is quite expensive."
"The solution is priced mid-range compared to the competition."
