Security information and event management (SIEM) is a device and environmental analysis strategy intended to help secure and protect company operations, data and personnel. By providing a comprehensive analysis of security-related details and related recommendations, SIEM tools assist through ensuring compliance and remediating potential or active threats.

A recent report published by the IMARC Group found that the global SIEM market reached almost $5.8 billion in 2023. The same report says the market is expected to climb to around $14 billion, especially with more companies investing more resources in protecting against potential threats and resolving vulnerabilities.
With that in mind, we take a look at the best SIEM tools and SIEM software solutions available today.
Those wishing to adopt SIEM or planning to upgrade a legacy SIEM tool to a modern platform should carefully evaluate the available tools. Features such as cloud and on-prem functionality, remediation capabilities and the platforms supported should be among the top areas to be considered.

SolarWinds Security Event Manager (SEM) is focused on log aggregation and threat detection. It can easily process and forward raw event log data to external applications for further analysis using syslog protocols, which is an area where it stands out from the competition.
I picked SolarWinds for its extensive log aggregation and log analysis functionality. This allows businesses to know the exact state of their devices, find the root-cause of each log and consequently implement strategies to improve the same. SolarWinds’ ability to share massive amounts of log data to other applications is a significant plus as well.

Splunk Enterprise Security offers cloud-based security-related event notifications and log monitoring. It can identify resource bottlenecks, failing hardware, capacity issues and other potential issues. As it evolved in the era of the cloud, it is particularly well suited to cloud-native environments.
Splunk Enterprise Security got on this list for being specially equipped with protecting cloud environments. It enables cloud-native organizations to easily establish security monitoring and unified visibility in the cloud. Its comprehensive visibility capabilities are coupled with 1,500+ detections, thousands of integrations and risk-based alerting. Splunk’s unified threat detection, investigation and response service is a security tool that many cloud-native companies should consider.

Datadog has designed its platform to be highly customizable to user needs. Datadog Security Monitoring makes it relatively easy to see at a glance what’s happening with all sources being analyzed. It offers security monitoring for dynamic environments, real-time security monitoring tools and root cause analysis functionality. There’s also a free trial that lets organization’s test drive Datadog to see if it fits their needs and requirements.
I chose Datadog Security Monitoring for its strong emphasis on user-configuration and customizability. In particular, organizations can utilize Datadog’s configurable rules to track down common attacker behavior and techniques. You can also customize which logs you want to index as you continue to ingest and process data. This is on top of having a customizable dashboard and user interface.

For organization’s requiring an on-prem solution, I recommend LogRhythm. You get a holistic security approach, getting features such as embedded modules, threat monitoring and automated detection and response. It also provides streamlined incident investigation and analysis capabilities for organizations looking for a bird’s-eye-view of their IT infrastructure. For on-premises deployments, LogRhythm also puts emphasis in providing highly-usable content for compliance and regulatory requirements.

RSA NetWitness carved its name on this list for being an all-around security solution built for bigger organizations. It provides visibility across a wide range of capture points, as well as having smart analytics and automation capabilities for both known and unknown attacks. I find that large businesses in particular will benefit from NetWitness’ fast-performing threat detection — which is able to reveal the full attack scope in a timely manner.

ManageEngine Log360 is a SIEM that serves businesses of all sizes but is especially suited to small business (SMBs) deployments. It also integrates well with a series of other security and monitoring products that the company offers.
ManageEngine Log 360 is on this list for being especially useful to SMBs. It has all the SIEM features SMBs will benefit from, such as event log analysis and cloud infrastructure monitoring, as well as threat detection and automated responses. I particularly like how ManageEngine makes it very accessible for businesses to try Log360’s premium features for free — via a generous 30-day free trial.
IBM QRadar is a threat detection and response solution that includes an SIEM module. As such, IBM Security QRadar SIEM is especially suited to enterprises that are heavily invested in IBM tools and systems, as well as large enterprise deployments.
I picked IBM’s QRadar SIEM as a smart choice for companies that have already heavily integrated IBM products and tools into their workflow. Fortunately, Security QRadar also offers a good number of integrations with other third-party services — making it a viable SIEM option even for companies that don’t have an IBM ecosystem.

Trellix Security Operations and Analytics contains the bones of the old McAfee Enterprise Security Manager SIEM platform and is now a module known as Trellix Enterprise Security Manager. That SIEM offering was Active Directory-based and well suited to Windows environments. But Trellix has expanded it to offer strong cloud support.
AlienVault Unified Security Management platform (USM) is now AT&T USM Anywhere. It discovers assets and gathers data about running services, users, operating systems and hardware information. This asset focus means it can pick up any devices in the environment that it protects.
USM Anywhere got its place on this list as a solid tool for businesses that prioritize threat detection and asset discovery above all else. It can detect vulnerabilities and threats on the cloud, the network or on-prem — making it a virtual detection solution for all types of IT infrastructures.
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.
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.
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.
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.
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.
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.
The SIEM tools 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.
