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.

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

"Being able to push consistent firewall rules and configuration changes across multiple FortiGates saves a ton of time and reduces errors compared to managing each device individually."
"The most valuable feature is the central configuration for firewall policies."
"Fortinet FortiManager allows you to manage multiple FortiGate devices from a single console, and this is a valuable product feature."
"Fortinet FortiManager allows a full view of all the devices on the network from one location."
"The features are good."
"The product is a combination of management and monitoring from the same interface."
"The setup is very simple."
"The solution is very stable."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
"You can utilize the main file from various vendors for integration."
"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."
"The best feature is the solution's entire credibility with all vendors."
"It is a scalable product."
"We do not have any issues stability-wise."
"It gives us a good overview of what's happening in our networks and the devices in the networks."
 

Cons

"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 response times from technical support need to be a bit quicker."
"Troubleshooting for Fortinet products is more difficult than competing products like Cisco and Palo Alto."
"The dashboard could use some improvement."
"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."
"Within the management of some features on FortiManager, specifically the management of user objects used for VPN service, FortiManager is quite weak."
"The graphical user interface could use improvement as it appears complex and not user-friendly."
"We have some visibility issues with the reporting."
"Reporting. Even though this is available in separate software (iSPI) there is potential in making the reporting more SLA-aware and more intuitive."
"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."
"Right now, we have open tickets and they are not closing as expected."
"We had some issues with some of the features, some modules are not meeting expectations."
"The way the solution currently works means I'm not able to customize my own reports."
"The resources utilized could be a bit higher, and that is one of the challenges that isn't optimized"
"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."
"The dashboards are not customizable and it's not user-friendly."
 

Pricing and Cost Advice

"Fortinet is a high-end product and the cost is high. They should consider reducing the price, especially for existing customers."
"The licensing costs depend on how many devices you want to use."
"The pricing is based on a licensing model by feature."
"FortiManager is reasonably priced - I pay around US$40,0000 per year, which covers fifty locations."
"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."
"FortiManager isn't expensive, but its cost is dependent on which services are required."
"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."
"This is an affordable solution, and its licensing model is based on the number of devices."
"The solution is quite expensive."
"The solution is priced mid-range compared to the competition."
"It's an expensive solution."
"It is more inexpensive than other products in the market."
"I wasn't involved in the pricing, but I think it's quite expensive."
