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

"The initial setup was straightforward."
"FortiManager's best feature is the integration of administrator users."
"For the whole security fabric from Fortinet, with a simple click you can see if some workstations or services are affected by an attack, you can really easily quarantine it, check the solution, and fix it, and it's very good from a security perspective."
"If we use the Fortinet FortiManager to replicate the configuration and want to install ten FortiGate on ten sites, you don't have to set configuration on all ten because you can configure one FortiGate and the Fortinet FortiManager will replicate the configuration on all FortiGate devices."
"The solution has the best stability for application control and inspections."
"I pushed templates from FortiManager to our site, and they were deployed successfully."
"This solution enables you to centralize the rules and the configuration of all the equipment."
"It can scale well."
"So actually it makes our life a lot easier in identifying if you've got problematic areas."
"Because of the topological network mapping, our management can quickly take action when there's a network problem."
"We need fault, availability, performance, and security."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
"The most important benefit is to have one controller and to get all information to a single point."
"It is a scalable product."
"The best feature is the solution's entire credibility with all vendors."
"Topology creation is the most valuable feature."
 

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."
"In future updates, I would like to see more customization and AI integration."
"It requires a lot of resources. This is the main challenge."
"Pricing-wise, it could always be less, even though it is less expensive than Palo Alto."
"The CLI could be enhanced."
"The information extraction through command lines was could improve to some extent. Although there were some command lines available, there were not enough options. For instance, I needed to obtain the management IP address of my two Fortigates, but the Fortinet FortiManager did not provide me with the IP address on the LAN interface. I attempted to find this information through the command line but was unsuccessful. I also searched for articles on the internet, but could not find a solution. This is an aspect that could be improved or potentially there is a method to access this information that I have yet to discover."
"FortiManager needs to handle different firewall versions more efficiently."
"I put seven for scalability because it is a bit complex to add some new devices and new users, or that function could be simplified."
"I haven't had a great experience with this solution because the dashboards are not customizable and it's not user-friendly."
"Reporting. Even though this is available in separate software (iSPI) there is potential in making the reporting more SLA-aware and more intuitive."
"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."
"I want to have some of those nicer features for when networks go flapping. I want to receive alerts before problems occur rather than when it actually goes down."
"The cost is high comparing to its competitors, but the results are awesome."
"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."
"We are very dissatisfied with the technical support. We have multiple demands and even the engineers are not satisfied."
"Only to improve the GUI."
 

Pricing and Cost Advice

"On a scale from one to ten with one being the highest price and ten being the lowest price, I would rate FortiManager's price at three."
"Fortinet FortiManager is a low-priced product."
"Compared to Check Point or Cisco, Fortinet FortiManager is more affordable but it is still on the higher end."
"Fortinet is a high-end product and the cost is high. They should consider reducing the price, especially for existing customers."
"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 is reasonably priced - I pay around US$40,0000 per year, which covers fifty locations."
"Fortinet FortiManager can be expensive."
"For us, it is a little bit expensive."
"It's an expensive solution."
