Offers best practice recommendations and supports various compliance standards
Security Hub provides insightful information about what is running and where there might be weaknesses. It offers best practice recommendations and supports various compliance standards such as ISO and PCI DSS. Enabling these compliance checks helps identify non-compliant services and suggests steps to achieve compliance. The main advantage is providing information and compliance insights rather than prevention.
ROBERT-CHRISTIAN - PeerSpot reviewer
Has many predefined correlation rules and is brilliant for investigation and log analysis
It is very complicated to write your own correlation rules without the help of Splunk support. What Splunk could do better is to create an API to the standard SIEM tools, such as Microsoft Sentinel. The idea would be to make it less painful. In ELK Stack, Kibana is the query language with which you can search log files. I believe Splunk has also a query language in which they search their log files, but once you have identified the log file that you want to use for further security correlation, you want to very quickly transport that into your SIEM tool, such as Microsoft Sentinel. That is something that Splunk could make a little bit less painful because it is a lot of effort to find that log file and forward it. An API with Microsoft Sentinel or a similar SIEM tool would be a good idea.

Quotes from Members

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

Pros

"The advantage is that it is cloud-native, and we do not need to install agents or sensors to find findings."
"I find all of the features to be highly valuable."
"The most beneficial aspect of Security Hub is its proactive capability, allowing us to identify potential security issues before they escalate."
"It's a security posture management tool from AWS. Basically, it identifies misconfigurations, similar to Trusted Advisor but on a larger scale."
"Finding out if your infrastructure is secure is a valuable feature."
"AWS Security Hub's unified dashboard does help streamline my process of identifying vulnerabilities, but we don't use Inspector."
"The most valuable features of the solution are the scanning of all the cloud environments and most of the compliances available in the cloud."
"I like that AWS Security Hub currently has several good features, around four or five. The technical support for AWS Security Hub is also responsive."
"Being able to track impossible travel logins and things of that nature is valuable. We can track user logins from various IPs, various countries, and at various times to see if everything adds up."
"The most valuable feature is the DSS, also known as SPL, because it allows users to script advanced queries with limited knowledge."
"Splunk Enterprise Security stands out for its ability to integrate with existing security tools, provide informative dashboards, and offer IT Service Assurance functionality that goes beyond basic threat detection to include service performance monitoring."
"The feature that I have found most valuable with Splunk is the ability to sift through a bunch of data very quickly."
"My customer was integrated with many third-party credentials and other threat sources as well. The integration part was seamless and easy. The rates for allocating valuable information and IOCs from different sources are also good."
"There are lots of free learning materials on their website."
"The benefits my company has seen from the use of Splunk Enterprise Security revolve around the speed of detection it offers."
"The correlation capabilities are the first value that our clients say they like with Splunk."
 

Cons

"It's not user-friendly. Too much going on, too many unnecessary findings, not very visual. You can't do much compared to other similar tools that are cheaper and better."
"There is room for improvement in implementing AI capabilities. It would be beneficial for Security Hub to implement preventative measures and to directly apply recommendations instead of just suggesting them."
"From an improvement perspective, there is a need to add more compliance since, right now, AWS Security Hub only provides four to five compliances to control the tool."
"There is room for improvement in implementing AI capabilities."
"Shortening the response time for support tickets, particularly in production issues, could make the service more efficient."
"I would like a more fine-grained capability for creating custom rules and a more user-friendly experience programmatically in writing queries and configuring custom security rules, making it quicker and easier."
"The telemetry doesn't always go into the control center. When you have multiple instances running in AWS, you need a control tower to take feeds from Security Hub and analyze your results. Sometimes exemptions aren't passed between the control tower and Security Hub. The configuration gets mixed up or you don't get the desired results."
"It is not flexible for multi-cloud environments."
"I love the solution, but I would like to see more accessibility to the machine-learning capabilities that are sprinkled around Splunk."
"For us, the area that Splunk Enterprise Security can improve is performance optimization."
"It is a challenge to manage the environment in such a way, that one’s log, even with the bandwidth license, isn’t exceeded."
"The price has room for improvement."
"I'd love to see more integrations, which is one of the primary points of the key node with Splunk Enterprise Security."
"It would be good if the solution had some kind of copilot to automate or help write correlation searches."
"Technical support needs to be more responsive."
"The threat detection library needs to increase the frequency at which the playbooks are updated."
 

Pricing and Cost Advice

"The cost is based on the number of compliances, core checks, and services required, and for more than 10,000 recommendations, the charge is just one dollar."
"AWS Security Hub is not an expensive tool. I would consider it to be a cheap solution. AWS Security Hub follows the PAYG pricing model, meaning you will have to pay for whatever you use."
"There are multiple subscription models, like yearly, monthly, and packaged."
"AWS Security Hub's pricing is pretty reasonable."
"Security Hub is not an expensive solution."
"The price of AWS Security Hub is average compared to other solutions."
"The pricing is fine. It is not an expensive tool."
"The price of the solution is not very competitive but it is reasonable."
"Splunk has always been on the expensive side."
"Splunk Enterprise Security's pricing is competitive."
"I think that most of the monitoring solutions are expensive."
"Be upfront about your needs and expectations. Splunk is great to work with."
"We have seen ROI and improvements as we have continued to use the product, but they are more reactive."
"Pricing and licensing are quite high compared to other tools or SIEM tools, but the features justify it."
"I think that most of the log analytics solutions are expensive and I'm not sure if it's worth it."
"Most people share the same thought that the ingestion rates can get pretty pricey. There is a lot of work we do to curate the data that we send to Splunk so that it is not too noisy or too expensive."
