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

"FortiManager's ability to scale is good."
"Provides good and detailed log management."
"In general, I have no serious concerns about this product so I have no problems recommending it."
"There is something called zero-touch provisioning, where you can add a new device without any configuration. You just add it to FortiManager and then forget about it."
"The functionality is good; it has good features and it works well for us, with multiple features in one box, which helps to avoid needing a lot of equipment and makes it unique."
"FortiManager's most valuable features are web-based or web-rule-based policies, SD-WAN, and the ease of upgrading to new firmware."
"The technical support for us is great."
"Overall, I find that this is a good solution and it gives me everything that I want."
"Real time network monitoring application: It is very stable, which provides quick root cause analysis (RCA) for any network faults."
"Scalability is actually one of the reasons why we picked Node Manager."
"We need fault, availability, performance, and security."
"It has gradually evolved over time from a long initial stage to now where it's a very high scale product."
"Topology creation is the most valuable feature."
"Overall, the tool helps maintain the health of the network."
"Most valuable function would have to the internal causal engine and its root cause analyzer which keep us updated on critical errors and incidents in our network environment."
"You can utilize the main file from various vendors for integration."
 

Cons

"Fortinet is releasing quite a lot of new versions and I would say that most of the versions are not well tested before they're pushed out. Even the new versions sometimes are a bit buggy before it's all correct."
"The price is a bit too high."
"When we have a specific configuration pushed it does take some time to be deployed on the actual firewall."
"The user interface can feel clunky, especially for more complex tasks such as managing large-scale policy packages or custom scripts."
"The GUI is not ideal."
"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."
"The GUI could be updated. It's not as good as it could be and is something the solution should improve in an upcoming release."
"The product is not very stable."
"The solution should integrate with NAC servers."
"Sometimes technical support is not so amazing. We need to wait a long time to get a solution for a ticket."
"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."
"I would say that they definitely need to improve their support features — this is a problem. When I open a ticket, usually they respond very late."
"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."
"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."
"We have not had a good experience with technical support from OpenText. Many cases take a month to be resolved."
"The deployment architecture and installation part needs improvement."
 

Pricing and Cost Advice

"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."
"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 can be expensive."
"In comparison with other products, the price of FortiManager is reasonable."
"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."
"Fortinet FortiManager is a low-priced product."
"It's an expensive solution."
"I wasn't involved in the pricing, but I think it's quite expensive."
"The solution is quite expensive."
"The solution is priced mid-range compared to the competition."
"It is more inexpensive than other products in the market."
