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

"FortiManager offers a full zero-touch provisioning feature that allows us to create a template of our devices and onboard them remotely without visiting the site."
"It is a stable, reliable product."
"Everybody is quite happy with the way that the graphical user interface works."
"Fortinet FortiManager allows a full view of all the devices on the network from one location."
"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."
"FortiManager helps automate configuration deployment, allowing us to plan and schedule configurations."
"The most valuable feature is having one object on all networks, which allows for implementation only once."
"Even without the security orchestration, just the fact that the customer could request the firewall team to configure a job that would roll out a configuration on the firewalls and it could be deployed across all the firewalls through the FortiManager was a big improvement compared to deploying the new firewall rule on each firewall sequentially."
"A good enterprise-level solution."
"The solution is very stable, and once it's configured properly, stability and maintenance are strong with no issues in performance."
"It is a good network monitoring, enterprise solution, and a meta-monitoring solution with good visualization."
"We do not have any issues stability-wise."
"The best feature is the solution's entire credibility with all vendors."
"Topology creation is the most valuable feature."
"It has gradually evolved over time from a long initial stage to now where it's a very high scale product."
"So actually it makes our life a lot easier in identifying if you've got problematic areas."
 

Cons

"Regional support in African countries needs to be improved."
"One of the biggest limitations is the grammar of the API – not the API itself."
"The solution has to be enhanced to manage new switches."
"The GUI is not ideal. It needs to be improved. It should be more user-friendly."
"I think the initial setup is too complicated because there are several versions of the operating systems, so you don't have directly connections between two devices."
"Wizards could be improved in pushing policies."
"The pricing and support could be improved."
"This solution needs more experienced technical support staff. There's nothing special about it compared to other vendors."
"I haven't had a great experience with this solution because the dashboards are not customizable and it's not user-friendly."
"It is hindering us so much because we cannot give it directly to customers because after a number of connections, the system goes down within one minute."
"The deployment architecture and installation part needs improvement."
"Customer service is not good compared to IBM or Zenoss support."
"Reporting. Even though this is available in separate software (iSPI) there is potential in making the reporting more SLA-aware and more intuitive."
"We have not had a good experience with technical support from OpenText. Many cases take a month to be resolved."
"They should add AI options in the product's next release."
"In terms of improvement, I would say that the resources utilized could be a bit higher, and that is one of the challenges that isn't optimized to my expectations."
