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

"It can scale well."
"Technical support is great. When we have sent urgent tickets and they do reply back within fifteen minutes."
"It has multiple features in one box, which helps to avoid needing a lot of equipment. This is something that makes them unique."
"The reports feature is excellent."
"We look at the traffic to segment the network and it improves and increases the performance. When we have a mobile connection and local laptops are on the same network. We have seen a big performance upgrade."
"I like the rapid deployment feature. I also like that it's easy to troubleshoot. FortiManager is amazing because we can have a centralized policy. All our devices are integrated, and we can also engage in troubleshooting. We can use it for different deployments. One fantastic feature is the ability to create a version and deploy it immediately."
"FortiManager's most valuable features are web-based or web-rule-based policies, SD-WAN, and the ease of upgrading to new firmware."
"The centralized management of policies and certificates, coupled with the capability to handle multi-site deployments effectively, provides streamlined operations."
"It is stable for fault and availability."
"Our monitoring and network teams of less than 100 people use this solution. The availability and fault monitoring are good."
"Topology creation is the most valuable feature."
"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."
"If you install one node on Network Node Manager and want to scale it up, it's pretty easy to create more nodes."
"It's quite a mature solution."
"The platform has good stability."
"Overall, the tool helps maintain the health of the network."
 

Cons

"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."
"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."
"The graphics interface between Fortinet FortiManager and any Forti products should be standardized."
"Issues arise when customers experience unstable electricity or poor grounding conditions."
"FortiManager could be more user-friendly."
"The response times from technical support need to be a bit quicker."
"The areas that need improvement are implemenation and support. In terms of implementation, it mainly needs clear documentation."
"The documentation could be better."
"The dashboards are not customizable and it's not user-friendly."
"They should add AI options in the product's next release."
"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."
"We had some issues with some of the features, some modules are not meeting expectations."
"Only to improve the GUI."
"The way the solution currently works means I'm not able to customize my own reports."
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
"Reporting. Even though this is available in separate software (iSPI) there is potential in making the reporting more SLA-aware and more intuitive."
 

Pricing and Cost Advice

"Fortinet FortiManager can be expensive."
"FortiManager is reasonably priced - I pay around US$40,0000 per year, which covers fifty locations."
"Fortinet is a high-end product and the cost is high. They should consider reducing the price, especially for existing customers."
"For the licensing fee, we paid around 10,000 to 15,000 euros."
"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."
"Fortinet FortiManager is costly."
"The pricing model is affordable."
"For us, it is a little bit expensive."
"It is more inexpensive than other products in the market."
"It's an expensive solution."
"The solution is priced mid-range compared to the competition."
"The solution is quite expensive."
"I wasn't involved in the pricing, but I think it's quite expensive."
