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 like the central management capabilities."
"The initial setup was straightforward."
"For the ROI, for a five-year project, Fortinet FortiManager would be the best option to use."
"It's very easy to install, and it's easy to discover and communicate with your device."
"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."
"The most valuable feature is the central configuration for firewall policies."
"The most valuable features are the centralized management of the firewalls, by unifying the deployment process of the policies among many of the firewalls or virtual domains that you have, and it is very easy to install and use."
"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."
"A complete solution for network monitoring."
"The platform has good stability."
"We need fault, availability, performance, and security."
"Our monitoring and network teams of less than 100 people use this solution, and 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."
"Effectively monitor networks physical and virtual devices."
"I would recommend the solution to others due to the fact that it's quite stable and mature."
"Overall, the tool helps maintain the health of the network."
 

Cons

"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."
"For the IPSEC tunnels, Fortimanager doesn't have all of the features that are available on Fortigate."
"I prefer configuring rules and the VPN on the standalone device, not on the manager."
"The scalability has room for improvement."
"There may be a communication issue. However, other items may be the culprit, such as network connectivity. It depends on the customer's network."
"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 experienced a series of minor bugs that necessitated contacting technical support on several occasions."
"The documentation could be better."
"The technical documentation takes experience and much reading to master."
"It is hindering us so much because we cannot give it directly to customers because after a number of connections, the system goes down within one minute."
"I would say that they definitely need to improve their support features — this is a problem. When I open a ticket, usually they respond very late."
"The cost is high comparing to its competitors, but the results are awesome."
"They should add AI options in the product's next release."
"The setup was complex and needs a medium kind of knowledge. The documentation is also not very good, i.e., a lot of things that are not written in the document are surprises."
"Sometimes technical support is not so amazing. We need to wait a long time to get a solution for a ticket."
"Configuration was a bit cumbersome for SNMP traps on the routers and configuration of the SPIs was a little complicated."
 

Pricing and Cost Advice

"Fortinet FortiManager can be expensive."
"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."
"For us, it is a little bit expensive."
"Pricing could improve a little bit so I rate it a seven out of ten."
"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 FortiManager is costly."
"I hope that the prices will become more competitive in subsequent releases, as the current pricing is perceived as somewhat elevated."
"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 is quite expensive."
"The solution is priced mid-range compared to the competition."
"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."
