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.

Pros

"The centralized management of policies and certificates, coupled with the capability to handle multi-site deployments effectively, provides streamlined operations."

"FortiManager's most valuable features are web-based or web-rule-based policies, SD-WAN, and the ease of upgrading to new firmware."
"You can configure it at your ease."
"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."
"Technical support is great. When we have sent urgent tickets and they do reply back within fifteen minutes."
"Without FortiManager, you cannot manage a complex environment across several sites with multiple firewalls."
"It is stable."

Cons

"When I installed it, I found it somewhat difficult to set up."
"This solution needs more experienced technical support staff. There's nothing special about it compared to other vendors."
"When I started, it was a bit difficult, however, now it's okay. It can be a bit complex for basic users."
"The price is a bit too high."
"The documentation could be better."
"It would be nice to have a virtual appliance as well."
"Wizards could be improved in pushing policies."
"There are a lot of bugs that need to be fixed, for example, the ZTP."

"Right now, we have open tickets and they are not closing as expected."
"Micro Focus Network Node Manager is not powered to drill down for traffic visibility."
"Micro Focus Network Node Manager is not the best when it comes to drilling down for more visibility, especially regarding traffic."

"Only to improve the GUI."
 

Pricing and Cost Advice

"I hope that the prices will become more competitive in subsequent releases, as the current pricing is perceived as somewhat elevated."
"The license model they use depends on the size and is not limited to the users."
"Fortinet is a high-end product and the cost is high. They should consider reducing the price, especially for existing customers."

"The pricing model is affordable."
"The price point is very good."
"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 solution is quite expensive."
"I wasn't involved in the pricing, but I think it's quite expensive."
"It is more inexpensive than other products in the market."
