SudeepMaydeo - PeerSpot reviewer
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.

Performanc Monitoring and Application Architect at Hewlett Packard Enterprise
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

"Fortinet FortiManager's best features allow me to operate multiple devices in one template, which helps me in my daily work as it reduces time and has positively impacted my organization by making it easy to centrally access and manage around 15 FortiGate devices from one portal instead of accessing every device standalone."
"Without FortiManager, you cannot manage a complex environment across several sites with multiple firewalls."
"My advice to anybody who is researching this product is that it is quite easy to use and the learning curve is not steep."
"The reports feature is excellent."
"The most valuable features are the centralized management of the firewalls."
"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."
"The functionality is good; it has good features and it works well for us, with multiple features in one box, which helps to avoid needing a lot of equipment and makes it unique."
"Provides good and detailed log management."
"The platform has good stability."
"It is stable for fault and availability."
"It's a good one."
"Scalability is actually one of the reasons why we picked Node Manager."
"It's quite a mature solution."
"It provides very good scalability from 200 nodes to 30,000 nodes and from 2,500 interfaces to 60,000 interfaces."
"A good enterprise-level solution."
"A complete solution for network monitoring."
 

Cons

"Performance issues should be improved. We have problems when we have more mobile connections than local devices. Most of us have two to three devices."
"I would like to be able to manage other products such as Endpoint and FortiAnalyzer through FortiManager. That is, the integration with other solutions needs to be improved."
"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."
"Regional support in African countries needs to be improved."
"We have some visibility issues with the reporting."
"There is a degradation of performance if we activate logs on FortiManager."
"The graphics interface between Fortinet FortiManager and any Forti products should be standardized."
"One of the biggest limitations is the grammar of the API – not the API itself."
"Reporting. Even though this is available in separate software (iSPI) there is potential in making the reporting more SLA-aware and more intuitive."
"The solution should integrate with NAC servers."
"Customer service is not good compared to IBM or Zenoss support."
"I haven't had a great experience with this solution because the dashboards are not customizable and it's not user-friendly."
"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."
"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."
"Sometimes technical support is not so amazing. We need to wait a long time to get a solution for a ticket."
"That is a little bit difficult for me because I haven't been personally dealing with the software directly, so the subcontractor has been the face in informing us what the product is capable of."
 

Pricing and Cost Advice

"FortiManager is reasonably priced - I pay around US$40,0000 per year, which covers fifty locations."
"FortiManager isn't expensive, but its cost is dependent on which services are required."
"The price point is very good."
"This is an affordable solution, and its licensing model is based on the number of devices."
"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."
"Our organization pays a monthly license fee for the solution."
"The licensing costs depend on how many devices you want to use."
"It's an expensive solution."
"The solution is priced mid-range compared to the competition."
"It is more inexpensive than other products in the market."
"I wasn't involved in the pricing, but I think it's quite expensive."
"The solution is quite expensive."
