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.

Scans servers and network devices through SNMP and reduces manual maintenance for our infrastructure team
I like how ServiceNow Discovery scans servers and network devices through SNMP. Most fields on our forms are auto-filled, reducing manual maintenance for our infrastructure team. Post Discovery implementation there is hardly any maintenance. There are three to four fields that are customized. Otherwise, 90% of the data is auto-filled. Discovery can also run in bulk, which is helpful for organizations that cannot run it during weekdays. With identification rules, if a configuration item (CI) isn't in the CMDB, you can simply add the IP address, and it will be automatically added based on criteria like name or serial number, making CMDB maintenance easier.

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."
"ServiceNow Discovery has played a vital role in improving service visibility through automated IT service management processes, including change and problem management."
"The product's discovery feature is valuable due to its accuracy, reliability, and the high prestige associated with the information it provides."
"I believe one of the great functionalities or improvements in ServiceNow Discovery is its ability to gather information about any Configuration Items (CIs)."
"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."
"This solution provides excellent insights."
"I like ServiceNow Discovery's overall structure and the way data comes in without creating a different dashboard or interface."
"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."
"The product provides great scalability features."
 

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."
"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."
"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."
"We would like more flexibility with the licensing. Discovery is bundled with ServiceNow's ITOM license. It was more affordable when it was sold separately, but we bought a package license to get more functionality out of the CMDB. We'd prefer to buy only the pieces we need instead of taking things we don't want or solutions that aren't yet mature enough to use."
"When you switch versions, for example, when you go from Paris to Quebec they will introduce many new things and occasionally things break when they do that."
"Improvements could include implementing chatbots to simplify ticket creation."
"The solution should improve the classes of discovery assets to disregard more junk data."
"The current limitation requires having mid servers or discovery servers in each data center for proper discovery, hindering the ability to discover assets across continents such as Asia Pacific and Europe."
"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."
"ServiceNow Discovery should improve its cloud capabilities."
"ServiceNow is very costly."
 

Pricing and Cost Advice

"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."
"FireMon Asset Manager's pricing has been reasonable and has worked well for us from a licensing standpoint."
"The price could be better. It's a bit on the pricey side."
"It is not recommended for smaller companies because of the price."
"The product is not cheap."
"ServiceNow Discovery has very broad pricing, so it becomes costly. It would be better if it had a pay-as-you-use licensing model because the total cost of ownership is quite high."
"ServiceNow Discovery is expensive, but the company has a monopoly and we need to use the solution. We use it because we do not have a choice."
"If the product is not deployed properly, it can be very expensive."
"I would rate the product's pricing a six out of ten. We had availed some discount from the standard pricing. Even then, the tool's pricing is expensive. You have to pay some vendor service fees for the product's implementation."
"It's on a yearly basis. We renew our contract for three years at a time."
