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.

Cons

"FortiManager would be improved by putting everything into a single console, including Microsoft O365 integration."
"Fortinet is releasing quite a lot of new versions and I would say that most of the versions are not well tested before they're pushed out. Even the new versions sometimes are a bit buggy before it's all correct."
"When I started, it was a bit difficult, however, now it's okay. It can be a bit complex for basic users."
"There is a degradation of performance if we activate logs on FortiManager."
"Its licensing model should be improved."
"The solution could improve by having better integration with other solutions other than Fortinet."
"Configuring Fortinet without internet access is challenging."
"Issues arise when customers experience unstable electricity or poor grounding conditions."
"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."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."
"They should add AI options in the product's next release."
"The resources utilized could be a bit higher, and that is one of the challenges that isn't optimized"

"The way the solution currently works means I'm not able to customize my own reports."
 

Pricing and Cost Advice

"Fortinet FortiManager is costly."
"Fortinet is a high-end product and the cost is high. They should consider reducing the price, especially for existing customers."
"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 license model they use depends on the size and is not limited to the users."
"Pricing could improve a little bit so I rate it a seven out of ten."
"Fortinet FortiManager is not expensive at all if you compare it with other vendors like Check Point and Cisco. Fortinet products are the least expensive on the market in the category of firewalls."

"FortiManager isn't expensive, but its cost is dependent on which services are required."
"I wasn't involved in the pricing, but I think it's quite expensive."
"The solution is quite expensive."
"It's an expensive solution."
"The solution is priced mid-range compared to the competition."
