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

"The most valuable feature is the central configuration for firewall policies."
"With Fortinet FortiManager, we can manage multiple firewalls and devices from a central point."
"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."
"It's a very rich, robust product."
"The centralized management of policies and certificates, coupled with the capability to handle multi-site deployments effectively, provides streamlined operations."
"It would normally take us a handful of days to install one FortiGate instance on one site. But with this technology, zero-touch deployment, we need just one hour or maybe as little as 30 minutes to install one site. It is much more efficient."
"The features are good."
"FortiManager's most valuable features are web-based or web-rule-based policies, SD-WAN, and the ease of upgrading to new firmware."
"Our monitoring and network teams of less than 100 people use this solution, and the availability and fault monitoring are good."
"We need fault, availability, performance, and security."
"The best feature is the solution's entire credibility with all vendors."
"We do not have any issues stability-wise."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
"A complete solution for network monitoring."
"It is a good network monitoring, enterprise solution, and a meta-monitoring solution with good visualization."
"The HPE suite is amazingly beautiful, has a fantastic user experience, and provides a high amount of simplification across transactions when adopting cloud technologies significantly."
 

Cons

"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."
"The product is not very stable."
"Configuring Fortinet without internet access is challenging."
"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 CLI could be enhanced."
"The GUI is not ideal."
"FortiManager would be improved by putting everything into a single console, including Microsoft O365 integration."
"Troubleshooting for Fortinet products is more difficult than competing products like Cisco and Palo Alto."
"We have not had a good experience with technical support from OpenText. Many cases take a month to be resolved."
"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."
"Customer service is not good compared to IBM or Zenoss support."
"Sometimes technical support is not so amazing. We need to wait a long time to get a solution for a ticket."
"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."
"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."
"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 setup was complex and needs a medium kind of knowledge. The documentation is also not very good, i.e., a lot of things that are not written in the document are surprises."
 

Pricing and Cost Advice

"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a six out of ten."
"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 licensing costs depend on how many devices you want to use."
"Our organization pays a monthly license fee for the solution."
"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."
"The license model they use depends on the size and is not limited to the users."
"Compared to Check Point or Cisco, Fortinet FortiManager is more affordable but it is still on the higher end."
"The solution is priced mid-range compared to the competition."
"The solution is quite expensive."
"It is more inexpensive than other products in the market."
"I wasn't involved in the pricing, but I think it's quite expensive."
"It's an expensive solution."
