Enterprise-level monitoring facilitates global observability and seamless script creation with intuitive tools
SmartBear, as a vendor, is focusing more on API management and testing rather than monitoring. AlertSite could benefit from more future-focused innovation, especially with competencies in generative AI. Additionally, support from AlertSite is not at an enterprise level since it is not offered 24/7. Outside of critical platform issues, there's no continuous support available.

Has helped reduce daily log volume significantly and streamline data routing across multiple destinations
Regarding complexity, as I mentioned before, Cribl is very simple to use. When I started 2.5 years ago, it was very easy to learn. I learned Cribl within a week, and even though I was a fresher at the time, it was easy to understand and not complex enough that someone would need to spend money on labs. It's not that complex to learn. Regarding cost efficiency, it's very good because nowadays the SIEM tools we use are too expensive on license, and SIEM tools base their license on how many logs get ingested. The unwanted logs, particularly firewall logs, represent a significant portion of unnecessary ingestion. Cribl saves our license by filtering out half of the firewall logs that are unwanted. Our main purpose for using Cribl is to save our license and save money. Currently, everyone is moving toward AI agents. We currently use regex, and AI agents could help us create those regex patterns to drop events or add raw data to events. Currently, we sit down, review the logs, and create regex patterns manually, which can be time-consuming. An AI agent could reduce this time. I read some articles indicating that Cribl Cloud has started using AI and considering MCPs and model context, but I'm not certain how far along they are. If Cribl asked me what they could improve, that would be my suggestion. The support is very good, and I had a few issues with Cribl where I raised support cases and received good responses, which is better than the quick response I didn't get from other SIEM tools and vendor tools I use. Compared to other SIEM tools, Cribl is cheaper than Splunk and DataDogs. However, it's still a bit expensive from my point of view, though I won't call it expensive. Overall, I think 99% of companies use Cribl before their SIEM tools, and compared to SIEM tools, Cribl is cheaper. Companies can use any SIEM tool such as Google, Splunk, or Cisco, and Cribl is cheaper than those SIEM tools. They might have a slight chance to reduce costs further, but I'm not the correct person to evaluate that since I'm more focused on the operational side. Regarding training, it was quite easy to grasp. It took me almost a week to understand the basic functionalities and what Cribl does. Getting more expertise took additional time, but basic functionalities and understanding what Cribl does took around four to five days. One point I want to mention is that Cribl could improve their labs or training materials in their Cribl Cloud or whatever portal they have.

Quotes from Members

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

Pros

"The return on investment of this solution is well witnessed in our organization because of the integration and various capabilities that it offers to interact with the upstream or downstream systems."
"The alerting capabilities were really helpful."
"If there are any issues, it triggers an alert within 30 seconds."
"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."
"My company went with AlertSite because as a tool, it's fast, easy to maintain, and provides great support."
"There are custom reports available along with the inbuilt reports."
"The alerting capabilities of AlertSite were really helpful."
"The platform's most valuable feature is the ability to transform data in real-time within the pipeline without sending it to a destination."
"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."
"Mostly because of the positive reasons, I would say it is easy to use, it is sustainable, the support is nice, the coding is quite easy to understand, there are a lot of functionalities there, you can do a lot of things, and the data migration is very easy."
"Cribl is a Ferrari for data analytics and monitoring, but you don't hand over the power or weaponize that tool for someone who doesn't know how to use it."
"The return on investment with Cribl is huge."
"Cribl feels a lot easier to use and more intuitive, gives you more capability, and you don't have to work as hard to set things up."
"Using Cribl for five years has simplified a lot of use cases when onboarding data, and because it is simplified, it takes less time, which is a huge win."
"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"
 

Cons

"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."
"In terms of support, it is all based on the cost of the subscription that our company purchased, but it wasn't great, and it could've been much better."
"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."
"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 could use a few changes to the user interface."
"I would like the ability to get more data points with regard to some of the unique requirements that we have."
"What needs improvement in AlertSite is the documentation, particularly the lack of documentation."
"Optimizing CPU utilization on the edge side is something that could be improved; we see, particularly on older hardware and older OSes, Cribl Edge service can eat up quite a bit of CPU resources compared to some other products we've used in the past, indicating there's room for improvement."
"Just sometimes, when I actually started using Cribl, I faced the issue where I was not able to connect the nodes."
"There is no alerting mechanism for the leader/worker nodes status."
"I do not think that if the pricing is on the higher side, it could be suitable for all types of users, such as small or medium ones."
"Improvement could be made in the logging area, as sometimes we encounter issues in a pipeline or something, and it's not immediately obvious when you look at the logs that the pipeline is failing."
"The deployment itself is a bit complicated and the documentation is not very clear."
"There is room for improvement in Cribl, as managing data from around forty thousand servers can become complex."
"Currently, Cribl Search is dedicated to one bucket at a time in the case of S3 buckets. The ability to search for multiple buckets would be awesome."
 

Pricing and Cost Advice

"We purchased the license once and had the option of selecting the number of user licenses."
"The cost is high."
"My company pays to use AlertSite, but I'm unsure of the exact costs because it depends on how many monitors you have."
"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."
"The product pricing is reasonable compared to other solutions."
