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.

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

"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."
"Stability is good within the product."
"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."
"I like the features on offer, for example SD-WAN; it's one single configuration point for everything, especially when you have a headquarters and branch, and the VPN is also beneficial, with very good correlation between FortiAnalyzer and FortiManager, and we find the pricing to be fair."
"Technical support was excellent."
"The setup is very simple."
"The solution is very stable."
"The integration is quite good."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
"You can utilize the main file from various vendors for integration."
"It is a scalable product."
"It's quite a mature solution."
"Effectively monitor networks physical and virtual devices."
"A good enterprise-level solution."
"The great thing about this solution is its compatibility for enterprise level organizations; if you need to install 10,000 or even 20,000 devices, it's easy to monitor, and the product's fault management is awesome."
"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

"One of the biggest limitations is the grammar of the API – not the API itself."
"In future updates, I would like to see more customization and AI integration."
"Pricing-wise, it could always be less, even though it is less expensive than Palo Alto."
"There may be a communication issue. However, other items may be the culprit, such as network connectivity. It depends on the customer's network."
"The product is not very stable."
"Their EDR products could be better. They need to dedicate more R&D to that area."
"We have some visibility issues with the reporting."
"FortiManager would be improved by putting everything into a single console, including Microsoft O365 integration."
"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."
"Right now, we have open tickets and they are not closing as expected."
"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."
"When I open a ticket, usually they respond very late. Some of the people I negotiate with seem undertrained."
"The deployment architecture and installation part needs improvement."
"The technical documentation takes experience and much reading to master."
"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."
 

Pricing and Cost Advice

"Fortinet is a high-end product and the cost is high. They should consider reducing the price, especially for existing customers."
"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."
"Compared to Check Point or Cisco, Fortinet FortiManager is more affordable but it is still on the higher end."
"The licensing costs depend on how many devices you want to use."
"For us, it is a little bit expensive."
"The pricing model is affordable."
"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."
"It's an expensive solution."
"I wasn't involved in the pricing, but I think it's quite expensive."
"The solution is priced mid-range compared to the competition."
"It is more inexpensive than other products in the market."
"The solution is quite expensive."
