Chan Lung - PeerSpot reviewer
Works very well as a single platform for policy management and audit compliance
The dashboard clearly shows the policies of a network environment. We can see which policies are critical or are always being used. We can also see which ones are not being used or have not been modified in a long time. We can see all the ports that the applications are using. We have all this information in the dashboard. After deployment, FireMon Asset Manager automatically shows the network topology. However, the dashboard is pretty fixed. It is not flexible. If I need to modify the dashboard, I need the help of their customer support. FireMon has streamlined policy deployment across multiple firewalls, making it easier to quickly implement changes. It has also improved our ability to comply with audits and be compliant with PCI DSS and ISO 27001 standards. The efficiency of deploying policies has increased significantly. The information provided by FireMon Asset Manager is helpful in making an organization's environment secure. It makes customers look into their policies and see if they need to be modified.

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 change modules. Whenever there is a change in the firewall, it automatically reflects on FireMon."
"The most valuable aspects of FireMon Asset Manager are its integrations and its ability to passively monitor the network for unknown assets."
"It offers a single platform for managing firewalls of different brands and simplifies policy deployment and auditing. It helps push policies to different firewalls, and it also helps with policy auditing."
"It's pretty robust, and it's agentless for the most part. So, you don't need to deploy agents, which makes it a lot easier to stand up."
"It has been stable since deployment."
"In the past, I found troubleshooting difficult in ServiceNow Discovery because I didn't have much exposure to the platform during that time, but then I explored some troubleshooting features, and I found that it wasn't that tough, so this is one of the qualities I like about ServiceNow Discovery. I also like that log reading in ServiceNow Discovery is much better than other tools. Another valuable feature of the tool is that you don't need to install many tools to deploy ITSM. You only need to subscribe to the modules to deploy the proper ITSM in your organization."
"ServiceNow Discovery works better than other products I've used."
"The solution can prioritize the discovery of IP ranges. The product automatically places all Discovery CIs into the correct class within the CMDB."
"The best thing about Discovery is maintaining all the CIs in one place. I can sort the data, export it to Excel for manipulation, and build reports like how many computers or servers we have and their capacity."
"We can find servers or services we were unaware of and stumble on vulnerabilities from those devices."
"We can scale the solution."
 

Cons

"It is not very good at monitoring the Check Point firewall, but it works very well with other firewalls such as Palo Alto, Fortinet, and Cisco ASA."
"While passive discovery remains important, active retrieval of asset details would be valuable, and this functionality is starting to be implemented, as I've observed in recent updates but it is not fully there yet."
"The discovery process could be improved. If incorrect credentials are entered, it should give an error message. That would make our work easy rather than having to troubleshoot why the issue is occurring."
"Without improvement in the patters, applications can't be discovered"
"The initial setup could be made easier. We hired professionals to implement it, and they trained our employees for ongoing processes."
"Discovery, while a bit pricey, integrates well with other tools and offers a centralized discovery solution. These aspects could be enhanced in the new release."
"The manual pattern-matching process is not only time-consuming but also presents challenges during system upgrades, demanding revisits to ensure compatibility."
"It's an expensive platform."
"I would rate technical support for ServiceNow Discovery as four. This rating is because there are features on the tool that never worked and despite calling our support, there were no results."
"It creates quite a bit of duplication, so that needs to be fixed."
"ServiceNow Discovery should improve its cloud capabilities."
 

Pricing and Cost Advice

"FireMon Asset Manager's pricing has been reasonable and has worked well for us from a licensing standpoint."
"FireMon is more expensive than other brands but justified by its comprehensive feature set. It includes several functions that might require additional subscriptions in other solutions."
"ROI (Return on Investment) is good. ServiceNow don't disclose the price publicly. They'll assess your organization's needs and then come up with a price."
"It costs a lot. It is probably close to over a hundred thousand. It's an expensive platform, but you can't compare ServiceNow's Discovery functionality to other discovery tools. It's not an apples-to-apples comparison of ServiceNow to a configuration management tool to an asset management tool because it does those things, but it's not those things."
"As per a general discussion I had with the stakeholders, I figured out that it is a costly tool. There is a need to make additional payments apart from the licensing fees for better support services from ServiceNow."
"Setting up and licensing for ServiceNow can be expensive, especially for enterprise service management."
"The product is not cheap."
"It's on a yearly basis. We renew our contract for three years at a time."
"This is expensive, but it meets our needs."
"It's a bit expensive compared to other products in the market, but it's worth the money you pay because it's far advanced in terms of features, automation, and capabilities compared to other products."
