"A Mature, Dependable Platform for Actionable Security Intelligence"
5/5
What do you like best about Fluency SIEM?

The product has matured beautifully into a highly dependable solution for collecting actionable security intelligence. It has evolved from a simple, budget-friendly compliance option into a core defensive asset, giving us a clearer security edge compared with our industry peers. Review collected by and hosted on G2.com.

What do you dislike about Fluency SIEM?

Fine-tuning the alerting thresholds can sometimes feel a bit obscure and overly complicated. While configuring the noise out of any platform is inherently tricky, the interface could do a better job of making the rule-testing workflow and paths clearer, so you don’t have to rely on their support desk as much.

"A great SIEM at a great price"
5/5
What do you like best about Fluency SIEM?

The team developing and supporting the tool is great. They are accommodating and responsive and always take the time to listen to concerns, feature requests or queries.

The tool is easy to deploy and has a very short runway to start delivering valuable results and insights.

Fluency is very accommodating with custom rules and integrations. They have, on several occasions, written new code for us for niche products and use cases. Review collected by and hosted on G2.com.

What do you dislike about Fluency SIEM?

The only real thing I'd criticise Fluency for is some of the dashboarding could be more polished / Flashy. Review collected by and hosted on G2.com.

"Fantastic product that has increased my SOC productivity tremendously"
5/5
What do you like best about Fluency SIEM?

I like the fact that the Fluency team provides personalized training and support. From pre-sales to implementation, the team is there to help you make the best use of the product and will do whatever it takes to get your team up to speed with the shortest learning curve possible. We were originally going to roll out a traditional SIEM like Splunk but were going to have to either hire additional staff that had set it up before or take existing staff and divert them from other tasks to learn how to administer it. Ultimately, while we waited on quotes from some of the big guys, Fluency had already spun up a proof of concept demo for us, and the security team was already starting to use it. The other great thing is that their engineering team will work with you to bring in any data you want. If there is not an out-of-the-box integration for bringing in data from a tool you use, the engineering team will build out a custom integration in a matter of days. Their pricing is also incredibly reasonable, and the flexible pricing options complement our business model. I'm excited to be an early adopter because I believe this tool will really shake up the market space if they keep it up! Review collected by and hosted on G2.com.

What do you dislike about Fluency SIEM?

I haven't found any serious downsides to Fluency. Early on, there were some missing "nice to have" features, but we provided that feedback to the Fluency team and they've since added those features as well as several others suggested by other customers. The platform is constantly improving. Review collected by and hosted on G2.com.

"Fluency stands out with its machine learning capabilities and Fluency Processing Language (FPL)"
5/5
What do you like best about Fluency SIEM?

To me, Fluency's two most likable features would be the machine learning behind the Event Watch and the Fluency Processing Language (FPL). Being able to write behaviors for Fluency's machine learning opens the door to a wide range of detections that aren't possible in non-ML tools without spending large amounts of time weeding out false positives and outliers. The addition of FPL greatly expanded what was possible with Fluency by allowing analysts and investigators to translate their thought and work processes into scripts that Fluency could execute itself. These scripts are a natural knowledge transfer process for organizations to retain analysts' knowledge as they transition to other organizations. It is an invaluable feature. Review collected by and hosted on G2.com.

What do you dislike about Fluency SIEM?

I'm not too fond of the legacy risk scoring that a few clients still use. The Event Watch system eventually replaced this feature; clients are moving away from it, but a few have not. Once it is fully depreciated and everyone has transitioned to Event Watch, I believe the experience will be even better. Review collected by and hosted on G2.com.

"At Last, a SIEM Workhorse for Today's Complex World"
5/5
What do you like best about Fluency SIEM?

Fluency is extremely fast, processing everything in real time. It is very comprehensive. The more data it has, the better and more refined the outcome. What is sometimes missed by other SIEMs is picked up and processed by Fluency. However, the best part of Fluency is the attitude Fluency has as a vendor. They are driven to get involved in their customer's success. They go many extra miles that others don't, and I say this after being involved in the SIEM market since SIEMs were first commercially available back in 2002. Review collected by and hosted on G2.com.

What do you dislike about Fluency SIEM?

The dashboard is very functional whereas other SIEM dashboards are more flashy. This is not to be confused with usability. The lack of flashiness is practical and geared towards serious MSSP and SOC operations. Review collected by and hosted on G2.com.

"A great product with a highly engaged team"
5/5
What do you like best about Fluency SIEM?

The team around Fluency is a highly engaged group that actively listens to their customer feedback, willing to improve their product where possible. Their progress has been evident during the past five years I've been this product. In an environment where we use many different systems and services, whether cloud or on-prem, the corresponding integration of such does not seem to be challenging for them. Over the years, a strong partnership has developed with an honest exchange of feedback and insights, which we highly appreciate.

Fluency's capabilities are a great support within our environment. While generating hundreds of gigabytes of log data daily, the system remains agile and flexible in how that data can be viewed and correlated. With Fluency, we significantly increased our insights on our attack surfaces and behaviors using the correlation and reporting capabilities and presenting the outcome on our custom dashboards. The ability to create our own custom alert rules with flexible logic allows us also to quickly adapt our lessons learned from incidents, penetration tests and other. It certainly provides the flexibility we need, which is probably, together with the team around it, one of its most significant advantages against its competitors Review collected by and hosted on G2.com.

What do you dislike about Fluency SIEM?

Fluency's user interface has made significant improvements throughout the last few years. Still, it might be a challenge for not so practiced users. However, they are working hard to improve this circumstance and gladly integrate the user feedback they receive. Review collected by and hosted on G2.com.
