Alerting capabilities have enabled timely escalation and resolution of issues
In AlertSite, I was monitoring the kiosks and servers for JetBlue Airlines. The servers would trigger alerts if there were any outages or issues with any of the kiosks, servers, or the ticketing tool. I monitored these alerts and escalated them to the concerned team to rectify them at the earliest…

Helps reduce log ingestion cost by dropping unnecessary events and customizing pipelines
The best feature in Cribl, when getting logs from some custom application, is the ability to break up logs that pile up together and come as one event. Cribl has a feature called JSON Unroll or Unroll function that allows you to differentiate the events; each event will come ingested as a single log instead of piling it up with multiple events. This is critical as this generally happens in CrowdStrike. This feature helps us significantly. When the ingestion is high from unwanted logs, logs not related to security purposes can be dropped by writing the parser function. By dropping events that are not required for security purpose monitoring, we can reduce the ingestion, which drastically reduces the cost as well. Cribl gives another option where I can store some logs, and when needed, I can pick them up from there. The interface is very handy and not very complicated, yet there are many functions you can perform. You can play around with numerous functions, parse there, and add UDMs to SecOps, which makes it really easy. To simplify the pipeline, when we go to the pipelines, there are vast options. We can make it specific requirements based on the customers. I would prefer a customized or simplified version. Cribl is a very good platform to work with, with lots of features that other platforms don't provide.

Quotes from Members

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

Pros

"The alerting capabilities were really helpful."
"The best feature of AlertSite is that it shows you a visual graph and also sends you notifications about errors, so you get immediate notifications about errors which means that your support team can start taking steps and more quickly make sure the site is up and that customer experience isn't interrupted in terms of using your system and your products. AlertSite is a very good tool. It's user-friendly, and you can see everything on the dashboard. Configuring it is also easy."
"This solution has numerous advantages. It's extremely simple to configure. Either digital monitors or single-URL monitors are simple to configure and build."
"If there are any issues, it triggers an alert within 30 seconds. When it triggers the alert, we go ahead and check it immediately. The alert is triggered on a real-time basis."
"I highly recommend AlertSite to other users."
"The alerting capabilities of AlertSite were really helpful."
"There are custom reports available along with the inbuilt reports."
"I found multiple features in AlertSite that I like. One is data monitoring history, for example, a history of the blackouts and the data. Sometimes, there's a glitch in the application that AlertSite can capture, and the tool notifies you about that glitch. It also identifies issues that could happen in the future. AlertSite is also a fast tool that you can use to monitor on-premise servers, internal applications, and even global applications. The data is available on a single UI in AlertSite, so there's no need to monitor and click on different applications or URLs. I also love that the tool is quite user-friendly, apart from being fast."
"Cribl offers other valuable features. For instance, you can replay data from an edge device, store your daily data in a stream, and replay specific event data into Splunk if a security incident occurs"
"My favorite option in Cribl is the Stream product."
"The best feature in Cribl, when getting logs from some custom application, is the ability to break up logs that pile up together and come as one event."
"Our experience with Cribl has been very smooth; everything runs seamlessly, there are no delays or sluggishness, which I really appreciate."
"The product's most valuable features include the internal management of events, coding perspective, data processing, and serialization."
"The capability to reduce logs in a user-friendly manner is a standout feature. Cribl allows us to view logs live as they are being processed, giving us quick feedback on the changes made."
"Cribl offers easy plugin configurations and source collection settings, allowing us to collect logs from any source."
"I'd rate the solution ten out of ten."
 

Cons

"What needs improvement in AlertSite is the documentation, particularly the lack of documentation. If there's a specific activity you want to do, you can't even find information on how to do it, so you have to contact the AlertSite support team to assist you, and only then would the issue be resolved. At the moment, it's not easy to find or get full documentation on how to deal with different issues. You always have to go back to AlertSite support and get help. The documentation for AlertSite could be improved and it's what I'd like to see in the next release of the tool because at the moment, the documentation isn't complete, so you'll have to contact support, but contacting support isn't an issue because the team responds to you quickly."
"One area that needs improvement in AlertSite is the slow UI. I'm using the classic UI because it's quite user-friendly, or in human-readable format, but it's a little slow. It takes time to load all the monitors, so if that could be sped up, that would be helpful. The AlertSite support team also needs improvement in terms of availability. Most of the agents in the team aren't available 24 x 7, so if there's something you need to discuss, you need to tell the support team ahead of time to schedule it. Multiple times, when a case comes up during weekends or whenever my team is doing an update, support needs improvement, availability-wise. I use AlertSite for synthetic monitoring, so whatever is available right now is okay, but if I want to request a new feature on a website, currently, the UI refreshes automatically. I would like to have the option on AlertSite to configure that manually. The UI auto-updates every few minutes, so if I can control that manually, that would be helpful."
"I would like the ability to get more data points with regard to some of the unique requirements that we have."
"AlertSite sometimes triggers false alerts or fake alerts, which needs to be rectified. When we see an alert and go ahead and run certain tests on it, the test always passes. However, on the main screen, it shows up as critical. Therefore, the false alert needs to be fixed."
"I could use a few changes to the user interface."
"It is not compatible with all of the product platforms that we use."
"Additionally, support from AlertSite is not at an enterprise level since it is not offered 24/7."
"Cribl doesn't have as many packs available"
"Cribl could have developed some version that can give backward compatibility."
"There have been several administrative issues. Another point is that the browsing functions aren't very intuitive."
"We encountered some issues with the syslog data stream, particularly with handling large databases and extensive data logs."
"Their documentation should be updated."
"There is room for improvement in the documentation and knowledge base, particularly regarding configurations like sources where logs are being ingested"
"Cribl could improve by offering easier integrations with enterprise products, similar to what Splunk provides."
"The sys logging could be enhanced to make it easier to identify errors, especially when dealing with multiple functions."
 

Pricing and Cost Advice

"My company pays to use AlertSite, but I'm unsure of the exact costs because it depends on how many monitors you have."
"We purchased the license once and had the option of selecting the number of user licenses."
"The cost is high."
"The product pricing is reasonable compared to other solutions."
"I would not say it is a cheaply priced tool as it has been doing wonders in the market. The tool has been budget-friendly for organizations."
