Key features of SIEM software
All SIEM software tools take care of log monitoring and management. Further important features include whether the tool is cloud-based, whether it can be hosted on-prem, whether it includes remediation capabilities, and what platforms it runs on.
Cloud
These days, most SIEM software is based in the cloud. Cloud-based products are easier to deploy, easier to manage, and simpler to run. And with so many enterprises operating in one or more clouds, SIEM tools in the cloud are a must-have. Some vendors provide SIEM on a Software-as-a-Service (SaaS) basis, and others offer it as a fully managed service.
Hosted On-prem
Some enterprises are averse to operating in the cloud due to privacy, security, or compliance reasons. They need to load SIEM on their own internal servers. Some vendors offer this option, while others don’t.
Remediation
SIEM originated as a way to simplify the compilation and analysis of security logs. It provided enterprises with a way to evaluate huge numbers of log entries and alerts and detect potential issues or intrusions. More recently, however, SIEM platforms have begun to add remediation capabilities. Some offer ways to automate a limited number of remediation actions. But a few tools provide access to a wide range of security remediations, either within the SIEM itself or via integrated or associated tools provided by the same vendor.
SEE: Everything You Need to Know about the Malvertising Cybersecurity Threat (TechRepublic Premium)
Platforms
The SIEM market is highly competitive. Most vendors have to provide tools that operate on all major operating systems and cloud environments. But there can be a few holes. Those with an extensive Google Chrome presence, for example, may find their SIEM options limited. It is vital, therefore, to verify that your potential vendor of choice is fully set up to run their systems in your environment.
How do I choose the best SIEM software for my business?
Every one of the products outlined here offers quality security protection and would be of value to any organization — and every organization needs some level of log-based real-time security analysis to help prevent and detect threats.
Making the right choice when selecting SIEM software is going to depend on company priorities, requirements, budget, level of IT expertise, and level of IT availability to assess and handle threats. If money is no object and tech staff isn’t able or willing to roll up its sleeves and tackle security risks, a managed SIEM like USM Anywhere may be the way to go. If company budgets are less robust and in-house talent and time are copious, SolarWinds SEM, Datadog, or AlienVault would be among the candidates. Otherwise, options such as LogRhythm, CrowdSrike, Splunk, RSA, IBM QRadar and ManageEngine should be high on the list of those to consider.
Methodology
The SIEM tools I covered here were selected based on an extensive evaluation of official security feature inclusions, prominence in analysis reports, and real-world user reviews. Each SIEM solution was analyzed based on its pros and cons, security features, and price offerings.
In addition, a heavy emphasis was placed on how each SIEM tool could be of use to certain use cases and businesses. This takes into account specializations per product and what types of organizations can best maximize their feature set.
Finally, the variety and number of integrations with third-party security services were also considered for this shortlist. This is to ensure the smooth adoption of the SIEM solution within a business’ existing architecture and the seamless monitoring of data points across the organization’s IT infrastructure for the SIEM itself.
