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

"I rate Security Hub ten out of ten for stability."
"The solution shows us our compliance score."
"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."
"AWS Security Hub has very good integration features. It allows for AWS native services integration, and it helps us to integrate some of the services outside of AWS. They have partners, such as Amazon Preferred Network Partners (APN). If you have different security tools around APN, we can integrate those findings with AWS Security Hub reducing the need to refer to different portals or different UIs. You can have AWS Security Hub act as a single common go-to dashboard."
"It's a security posture management tool from AWS. Basically, it identifies misconfigurations, similar to Trusted Advisor but on a larger scale."
"One of the most effective features of AWS Security Hub is the easy access to a dashboard with a ready-to-use security score."
"AWS Security Hub can check your infrastructure against multiple compliance frameworks. You can turn on or off specific frameworks based on your needs."
"The most valuable feature of Splunk Enterprise Security is website activity monitoring."
"Splunk is extremely flexible, which allows us to create custom visualizations along with other customizations."
"The ability to rapidly diagnose problems in production and non-production, across hundreds of log files, is the most valuable feature."
"It is a one stop shop as a full monitoring and alerting solution for operations and application analysis for most of our back-end systems."
"The technical support has been very good. They are very responsive and have been helpful."
"The most valuable feature of Splunk Enterprise Security is the threat intelligence integration because essentially having to go out and correlate all the data on our own becomes convoluted."
"Recently, Splunk upgraded to version 9.0.02, which includes excellent data dashboards and visualization effects."
"It allows for transparency into IT metrics for insightful business analytics."
 

Cons

"The solution should be easier to learn and use"
"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."
"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."
"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."
"Whenever my team gets some alarms from the central team, my team needs to initiate whether it's a real or false trigger. The central team needs to keep adjusting to the parameters or at least the concerned IPs, whether it's really from the company's pool of IPs, so the trigger process can be improved. In the next release of AWS Security Hub, I'd like a better dashboard that could result in better alert visibility."
"Many findings are too generic or irrelevant to the environment, which can lead to false positives."
"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."
"Shortening the response time for support tickets, particularly in production issues, could make the service more efficient."
"The threat detection system has room for improvement."
"Its interface could be improved."
"We will receive alerts only for the administrators and deployment servers, but not for all servers."
"The CIM model is the method Splunk uses to normalize data and categorize its important parts, but it is quite complex."
"It needs to improve the way to install third-party apps and enable installation without logging into splunk.com."
"Cybersecurity and infrastructure monitoring have room for improvement."
"This solution could be improved by better pricing in general and by easier installation."
"Could be more user friendly."
 

Pricing and Cost Advice

"Security Hub is not an expensive solution."
"The price of the solution is not very competitive but it is reasonable."
"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."
"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."
"The price of AWS Security Hub is average compared to other solutions."
"AWS Security Hub's pricing is pretty reasonable."
"The pricing is fine. It is not an expensive tool."
"The price of Splunk Enterprise Security fluctuates based on the customer, but I believe it's quite costly, especially for our clientele."
"Personnel costs are saved by not having to involve the domain developers from multiple teams when tracing a problem that spans multiple platforms."
"We have seen ROI and improvements as we have continued to use the product, but they are more reactive."
"The solution is a little expensive."
"Splunk Enterprise Security is expensive. I would rate the cost an eight out of ten with ten being the most expensive."
"The pricing is based on the volume of data fed into it, which can lead to substantial costs. This pricing model is complex and unpredictable, making cost management difficult."
"Splunk Enterprise Security is expensive but the solution is equipped with a lot of features."
"The licensing model can be expensive, but the value it provides is significant."
