Free SIEM

A SIEM solution is a Security Information and Event Management system that helps IT professionals manage cybersecurity. In broad terms, the SIEMs that encompass AI-powered event correlation gather and examine log data from various sources to monitor the health of the IT environment, detect threats, handle incidents in real time, issue security alerts, and produce compliance reports.

Still, it is widely known that implementing a SIEM tool demands significant time, effort, and money. Expenses tied to the enterprise license, yearly support, software maintenance, and skilled personnel to manage it place SIEM beyond the reach of small and mid-sized businesses (SMBs). That is why free SIEM has recently become more popular among them.

Free SIEM for businesses

Most of the best SIEM tools include a free trial letting customers test the waters and decide whether they wish to keep using the product. Even so, that amount of time is not enough to ensure small and mid-sized businesses' cyber protection over the long term.

Unified Security Stack is a free SIEM solution, also called Free Next-Gen SIEM, that offers a free edition to any company interested in cybersecurity. The free SIEM has been built to enable companies to protect themselves against all types of cyber-attacks. This advantage brings profitability to companies by reducing the total cost of ownership (CTO).

Unified Security Stack gathers and consolidates security-related data from an IT infrastructure. The system correlates and examines this log data in real time to expose activity patterns that could point to an intrusion attempt. Unified Security Stack, however, is not open source, unlike other free SIEM. Yet most of the application integration Unified Security Stack employs to process and analyze data is.

Features of Unified Security Stack

Unified Security Stack covers in the free version the same features as in its enterprise on-premise version:

• Number of data sources: Unlimited
• Updates: Monthly Unified Security Stack engine updates
• Multitenancy: Supported
• Log Management
• Identity management
• Dashboard and Report Builder
• Vulnerability Scanner
• Asset Scanner and Manager
• Incident Response
• HIDS and NIDS
• Compliance Management
• File Tracking and Classification
• Threat Intelligence
• Cloud Monitoring (AWS, Azure, GCP)
• Endpoint Protection integration

However, the free SIEM presents some limitations in its free edition in terms of:

• Log retention lasts only 30 days, meaning companies cannot produce compliance reports.
• Technical support is not included. Assistance is available through the Community, forums, and documentation.

Therefore, if your company is looking to meet compliance standards, it’s recommended to purchase the cost-effective enterprise on-premise version or adopt cloud SIEM. Bear in mind that Unified Security Stack is notable in the industry for making cybersecurity more accessible through its free SIEM and cost-effective versions (on-premise and SaaS).
