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

"The product is a combination of management and monitoring from the same interface."
"The most valuable feature is the centralized management console."
"For the whole security fabric from Fortinet, with a simple click you can see if some workstations or services are affected by an attack. You can really easily quarantine it, check the solution, and fix it."
"There is something called zero-touch provisioning, where you can add a new device without any configuration. You just add it to FortiManager and then forget about it."
"The most valuable features are the centralized management of the firewalls."
"It has multiple features in one box, which helps to avoid needing a lot of equipment. This is something that makes them unique."
"Fortinet FortiManager allows a full view of all the devices on the network from one location."
"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."
"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."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
"A good enterprise-level solution."
"It is stable for fault and availability."
"Topology creation is the most valuable feature."
"Overall, the tool helps maintain the health of the network."
"It is a scalable product."
"You can utilize the main file from various vendors for integration."
 

Cons

"This solution needs more experienced technical support staff. There's nothing special about it compared to other vendors."
"The reporting details have room for improvement."
"The interface could be improved. It is split up into different areas, which makes it more difficult to navigate and get the right section of the correct file. The solution is quite expensive, so it would not be suitable for small to medium sized organizations."
"Its licensing model should be improved."
"For the IPSEC tunnels, Fortimanager doesn't have all of the features that are available on Fortigate."
"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."
"We have some visibility issues with the reporting."
"The solution should be more open to other products."
"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 powered to drill down for traffic visibility."
"The dashboards are not customizable and it's not user-friendly."
"The deployment architecture and installation part needs improvement."
"The solution should integrate with NAC servers."
"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."
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
 

Pricing and Cost Advice

"The license model they use depends on the size and is not limited to the users."
"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."
"The licensing costs depend on how many devices you want to use."
"FortiManager is a bit expensive - I would rate its pricing three out of ten."
"Compared to Check Point or Cisco, Fortinet FortiManager is more affordable but it is still on the higher end."
"Fortinet FortiManager is a low-priced product."
"The pricing model is affordable."
"The price of Fortinet FortiManager is inexpensive."
"The solution is priced mid-range compared to the competition."
"I wasn't involved in the pricing, but I think it's quite expensive."
"It is more inexpensive than other products in the market."
"It's an expensive solution."
"The solution is quite expensive."
