Featured Reviews

Manikandan Kannan - PeerSpot reviewer
Simplifying log management by displaying detailed access information
The most valuable feature of Fortinet FortiAnalyzer is its ability to simplify and display logs clearly, providing details like which IPs are accessing the system, the destination, and the policies applied. This visualization and detail make managing logs more straightforward. In conjunction with our VMware setup, Fortinet FortiAnalyzer enhances organizational efficiency, meeting the standard log retention period for up to a year.
Ivan Kokalovic - PeerSpot reviewer
Facilitates backend service monitoring with efficient log retrieval and API flexibility
Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline. It boosts the knowledge of sales and customer support teams by allowing them to see the backend operations without needing to read the code. Its API is flexible for visualization, and its powerful search engine efficiently handles large volumes of log data. Moreover, its stability, fast search capabilities, and compatibility with languages like ANSI SQL enhance its utility in IT infrastructure.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"I have found incident management and also identifying new threats, analyzing the network traffic, and finding out the issues with the network traffic such as any security issues to be valuable. I also like the compliance reports."
"It supports SQL for logging and reporting. Log data is inserted into the SQL database for log view and report generation."
"The report templates are valuable. It works very well, and integrations also work well."
"This solution offers one view of incident management which has been the most valuable feature."
"I completely recommend Fortinet FortiAnalyzer to others."
"The solution does what it is supposed to. I want it to do reports for Fortinet and it does it well."
"The dashboard of Fortinet FortiAnalyzer is outstanding with very detailed information."
"The scalability is good. It is also good in the cluster nodes. You can make multiple FortiAnalyzer clusters groups, and you can distribute the logs between these FortiAnalyzer nodes. In other words, you can expand the scale."
"The best feature of Graylog is the Elasticsearch integration. We can integrate and we can run filters, such as an event of interest, and those logs we can send to any SIEM tool or as an analytic. Additionally, there are clear and well-documented implementation instructions on their website to follow if needed."
"The solution's most valuable feature is its new interface."
"This had increased productivity for the dev and support teams, because we are directly notifying them."
"The build is stable and requires little maintenance, even compared to some extremely expensive products."
"Graylog is very handy."
"Allowing us to set up alerts and integrate with platforms we already use, such as Slack and OpsGenie to alert users of these errors proactively, is also a very useful feature."
"Message forwarding through the in-built module."
"Storing logs in Elasticsearch means log retrieval is extremely fast, and full text search is available by default."
 

Cons

"Fortinet FortiAnalyzer needs to improve its pricing flexibility."
"In future releases, we'd like to see more granular reporting. The reports on offer right now are pretty short."
"I'm looking for something more efficient to analyze different foreign things. That's why FortiSIEM could compete with FortiAnalyzer."
"The integration between specific tenants and FortiAnalyzer can be simplified when utilizing a multi-tenant EMS for our FortiClient."
"Fortinet FortiAnalyzer could be improved by enabling features such as predictive analysis. We should implement AI features, correlation of different logs, and have predictive analysis, including alerts for policy violations."
"One area for improvement could be better support for third-party products, as it doesn't have as much visibility with these compared to Fortinet's own products."
"We'd like to see more embedded features."
"When it comes to pushing logs to a SIEM, most of the time we have some issues when it comes to filtering."
"There should be some user groups and an auto sign-in feature.​"
"Lacks sufficient documentation."
"Elasticsearch recommendations for tuning could be better. Graylog doesn't have direct support for running the system inside of Kubernetes, so it can be challenging to fill in the gaps and set up containers in a way that is both performant and stable."
"I hope to see improvements in Graylog for more interactivity, user-friendliness, and creating alerts. The initial setup is complex."
"More customization is always useful."
"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."
"Its scalability gets complicated when we have to update or edit multiple nodes."
"I would like to see some kind of visualization included in Graylog."
 

Pricing and Cost Advice

"Fortinet FortiAnalyzer is quite an expensive tool."
"The program is expensive."
"It is not very expensive when customers understand the value of this product and the importance of the information that it provides for security."
"The cost and pricing should be in accordance with the calculation of log storage capacity for a time period required for historical analysis."
"I rate the product's price a six on a scale of one to ten, where one is cheap, and ten is expensive."
"I won't say the solution is too costly since it is available at a fair price."
"When you compare with other firewall vendors, FortiAnalyzer is quite competitive in pricing."
"I rate FortiAnalyzer six out of 10 for affordability. FortiAnalyzer pricing isn't steady. It changes each quarter or year. That's one of the main problems in West Abaco because most businesses here are small or medium-sized enterprises. It makes budgeting complicated. You always want to pay the same price on the subscription."
"​You get a lot out-of-the-box with the non-enterprise version, so give it a try first."
"Consider Enterprise support if you have atypical needs or setup requirements.​"
"Graylog is a free open-source solution. The free version has a capacity limitation of 2 GB daily, if you want to go above this you have to purchase a license."
"I am using a community edition. I have not looked at the enterprise offering from Graylog."
"I use the free version of Graylog."
"It's an open-source solution that can be used free of charge."
"There is an open source version and an enterprise version. I wouldn't recommend the enterprise version, but as an open source solution, it is solid and works really well."
"We're using the Community edition."
