Audit function refines log retrieval and drives application assessments with evolving features
From a service assessment and authorization process perspective, when conducting an assessment on an application or system, we use controls essentially equivalent to the NIST 800-53 framework. This includes examining audit logs, data quality, and various KPIs required for log configuration. It factors into our application assessments. When producing documentation packages for application or system authorization, audit logging and monitoring are crucial parts of the assessment process. The evidence we gather includes screenshots and outputs from these tools and capabilities. For Microsoft Purview Audit specifically, we provide examples of audit function configuration and log output details, which are incorporated into our evidence documents.

Helps us detect cyber threats quickly and integrate multiple feeds effectively
Overall, the product is good, but when it comes to some infrastructure issues, we have to dig into more logs. There is no straightforward indication of an issue. Health check kind of dashboards are not available. More AI would help us, and more optimization, since security products run more queries. The AI module could suggest solutions, optimizing queries or workload balancing. If the product itself advises on running queries during peak times, it would be similar to what ChatGPT currently offers. We see quite a few issues on stability. Even last week, we faced something, and identifying bottlenecks is not easy. We need more SMEs, and there is no mechanism to tell us about indexer or search head issues. Self-monitoring dashboards could be beneficial. The technical support still requires more improvement. Often, primary support takes a lot of time and forwards most solutions to the engineering side. The primary support team has very limited knowledge to provide.

Quotes from Members

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

Pros

"The overall user experience with Microsoft Purview Audit is of higher quality than when it was branded as Compliance Center, and Microsoft consistently updates and evolves functionalities and the overall experience."
"We're easily saving at least one hour per day using this solution."
"The platform has significantly enhanced our operational insight into the overall Microsoft 365 environment."
"Splunk Enterprise Security's most valuable features are its stability and the robust Splunk Search Processing Language, allowing extensive customization and analysis capabilities."
"What I appreciate the most about the product is the flexibility with data ingestion and searching, which is very powerful; you can do whatever you want with it."
"The query functionality is very easy to use and fast to retrieve logs in comparison to other SIEM solutions."
"I have not seen any outages in the product in the past two years that it has been running in our company, so I think it is good when it comes to the stability part."
"I appreciate the integrations with the SOAR architectures and the expandability that can be used throughout the entire ecosystem of Splunk Enterprise Security."
"They have approximately 50,000 predefined correlation rules, which is quite a lot, and I find that good."
"I really appreciate the all-integrated SIEM feature of Splunk Enterprise Security, which serves as a one-stop shop to get all security tasks done."
"The most valuable features are how stable and easy to use Splunk is."
 

Cons

"We do have a Denial of Access happening."
"We are still in the early stages of leveraging Microsoft Purview Audit. Currently, it's primarily used for the audit function."
"Areas for product improvement include enhancing customization options and integrating more comprehensive compliance features."
"My company could benefit from doing more Splunk training with Splunk consultants teaching us how to use it."
"I would say we haven't seen any return on investment with Splunk Enterprise Security because we are still maturing and trying to get everything situated, and we're experiencing roadblocks with other teams not wanting to give us what we need."
"The solution's automation could be improved."
"Splunk could improve its default machine-learning models. Also, Splunk Enterprise's native threat intelligence isn't that good. I prefer a custom threat intelligence model."
"The only thing which can be improved is that they are too subjective on whom their Splunk4Good initiative can be applied. They market it as you only need to be a nonprofit, but there is more to it."
"Sometimes the communication with support happens with multiple staff. They should reduce the time to resolution."
". Having a trial version or more training on Splunk would be helpful."
"Both quality and speed are lacking. Quality-wise, tickets sometimes go in circles, with unnecessary complications and escalations requiring repeated explanations."
 

Pricing and Cost Advice

Information not available
"The licensing model can be expensive, but the value it provides is significant."
"The price of Splunk Enterprise Security is reasonable, falling somewhere in the middle range."
"The licensing costs are high for Splunk Enterprise Security."
"This product could use better pricing in general."
"I would highly recommend anyone evaluating this option to download the free trial which allows for the ingestion of 500MB of data per day in order to get a feel for what Splunk does at its core. It will get pricey once your ingestion rates start to sky rocket, but I would consider it expensive given the amount of information that it allows you to analyze and react on straight out-of-the-box."
"Splunk is a bit pricier, but the benefits and ROI are huge."
"It is pretty straightforward and based on the sizing. If I compare it with other competitors, it makes sense."
"Splunk has always been on the expensive side."
