Log data is one of the most valuable assets in IT security intelligence. Logs can give you a general overview of your network and let you gain powerful insights into its vulnerabilities.
Almost every device whether virtual or physical is able to generate logs. Raw generated logs coming from different vendors can be different in format and severity type. Solving security problems with this data would be very time-consuming.
When critical information is needed, it is usually difficult to find a solution from the large pool of different raw logs. They would have to be manually collected from each device and analyzed independently. Not very effective for today's security needs!
Here is our list of the top six log and event analyzers:
- SolarWinds Log & Event Manager – FREE TRIAL This log management system for Event and Syslog messages includes a machine learning function that analyzes consolidated log records and identifies troubling events. Runs on Windows Server.
- Datadog Log Analysis – FREE TRIAL A cloud-based service that gathers logs from Windows Events, Syslog, and application messages, consolidates them, and provides tools to view and analyze the data.
- Sematext Logs – FREE TRIAL A cloud-based service that collects, consolidates, and files log messages and includes access to files and a data viewer.
- ManageEngine EventLog Analyzer This alert-based log consolidator shows live data visualizations for incoming log records and draws performance thresholds to identify system problems. Runs on Windows Server and Linux.
- LOGalyze A free, open source log server and analyzer that provides compliance reporting for HIPAA, and PCI DSS. Installs on Windows Server and Linux.
- NetVizura EventLog Analyzer A log server and consolidator that includes a data viewer with analysis capabilities. Installs on Windows, Windows Server, and Linux.
Specialized event log management tools will make the IT admin’s life easier.
A log manager + analyzer tool collects and analyzes log event data automatically.
It can help you identify attack attempts, devices that are misconfigured, track user activity or even help you to meet regulatory compliance.
Event Log Managers are so helpful because they will automatically sort out all raw events and let you easily browse through them.
Security Information and Event Management “SIEM”, products provide real-time analysis of logs generated by network appliances or applications. In a few words, SIEM solutions are the synonym of a sophisticated event log analysis system.
The components of a SIEM can be (but are not limited to):
- Log centralization
- Data aggregation and collection
- Long-term storage
- Forensic Analysis
The following list of products have some or all of the common components of a good SIEM.
The Best Log Analysis Tools/Software of 2021:
SolarWinds Inc. is one of the leaders in IT infrastructure management and security software. They are trusted by more than 250,000 customers worldwide and have been in the market since 1999.
Among their favorites, “Log and Event Management” has been around since 2001 and is one of the industry’s most trusted log tools.
How does the Software work?
It automatically collects logs from multiple servers, applications, and network devices. Then it centralizes the logs into a single device. Finally correlates all logs, providing specific information such as event name, date, source, and severity.
What makes is so GOOD?
Most of the log analysis tools approach log data from a forensics point of view. But, Log and Event management uses log data more proactively. It can learn from past events and alert you on real-time before a problem causes more damage.
Troubleshooting can be simpler by using the pre-defined filters organized by categories. With these categories, you can specify more details of an event, such as source, destination, IP, port number and more.
To maintain adequate governance over the whole environment, the software can let you store and evaluate historical data. You can use stored data to run automated audits to establish a strong compliance.
But if you want more, the “Log & Event Manager” can provide extended capabilities for $4495.00.

Datadog is a cloud-based system monitoring and management platform that includes a range of modules, such as its log management and analysis systems. The main log management service offered by Datadog is called Ingest. This includes a log server to collect and consolidate log messages that derive from Windows Events, Syslog, and application status messaging. This package also includes a data viewer that has analytical tools built into it.
How does the software work?
The processing system for Datadog Ingest is resident in the Cloud. An agent program needs to be installed on-site in order to capture circulating log messages. The Agent uploads all detected messages behind the scenes on an encrypted connection. The Ingest server receives the messages, standardizes their format, and files them, while also displaying them live in the Datadog system dashboard. Saved messages can be recalled instantly and shown in the data viewer.
The analytical features of the Datadog Ingest data viewer include the typical sorting, grouping, and filtering utilities that can be expected from most data access tools. However, this system has some extra features that make it a powerful log analysis tool.
Some of the outstanding features from Datadog Ingest are:
- Data visualization graphs and charts
- A log analysis query builder
- An optional log parser
- An AI-drive alert threshold mechanism
- A guided problem detection customizer
- Specialized vendor-specific metrics collection
- Data aggregation and drill-down capabilities
As an online service, the Datadog software is instantly available without the need to install, host, or maintain any software other than the agent program, the management of which is organized by cloud-resident processes.
Price: Datadog Ingest is a metered service with a charge of $0.10 per GB of processed data per month.
Download: Datadog Ingest and other Datadog system management services can be accessed on a 14-day free trial.
Sematext Logs is a hosted version of ELK – the Elastic Stack. This is a cloud platform and it includes storage space for your logs. The suite of tools offered by this service includes Logstash, which collects and consolidates log messages and then stores them.
The core of the service is Elasticsearch, which enables you to search through log records. The tool lets you set up data search scripts that can also order, group, and format the records. Kibana is the interface for the ELK.
How does the software work?
You need to install an agent program on a server on your site. This will collect all log messages as they pass around your network and it will upload them to the Sematext server. As messages arrive, Logstash reformats them into a neutral format, which means that messages from different sources, such as Windows Events and Syslog, can be stored together and put into a single data pool. While converting the messages, the Sematext system also shows them live in the Kibana interface.
It is possible to feed extra information into the Sematext system, such as SNMP reports that will give you live network performance information to link into your log data. There are other ways to customize the Sematext system, such as setting up thresholds on any of the metrics the system gathers and commanding that they trigger alerts when crossed.
Some of the notable features of Sematext are:
- Log consolidation and filing
- Storage on a cloud server for up to one year
- Customizable data feeds and searches
- Decide your own metrics to collect
- Secure data transfers
- Performance alerts
- Analytical screens
- Customizable reports, plus out-of-the-box formats
Elastic Stack is very widely used for data management applications. The Sematext system gives you control over your own implementation without the hassle of hosting it.
Price: Sematext Logs is offered in three editions: Free, Standard (starting at $50 per month), and Pro (starting at $60 per month). Both of these paid plans come with a processing rate of 1GB per day and a retention period of seven days. The price increases with longer retention periods and larger processing volumes.
