Trunc & Log Analysis

Logs are invaluable for understanding system activity, but not all logs are created equal. Often treated as an afterthought by developers, logs can be incomplete, noisy, or difficult to decipher. The problem is compounded by the complexity of traditional SIEM and log management platforms, which require significant setup and expertise. Trunc is here to change that.

Making Sense of the Noise Instantly


At Trunc, we turn raw data into actionable intelligence right out-of-the-box. From the moment your first log event is received, Trunc begins to contextualize and categorize logs automatically. This means no complicated setup—our system is designed to work for you immediately.

Transforming Logs into Insights


Our advanced parsers are built to extract meaningful data from logs, removing irrelevant entries and highlighting the information that matters. Here’s an example using an SSHD log entry:

Raw SSHD Log:

      Accepted password for john from 149.1.x.x port 23414
      
While this log provides some information, it’s not enough to determine whether the event is legitimate or a potential threat. Now, imagine managing thousands of similar logs across multiple servers—it’s overwhelming and nearly impossible to manually analyze.

Trunc’s Enriched Insight:


      
          Login success via SSHD
          IP: 149.1.x.x (Germany)
          User: John

          Warnings:
          - IP is a Tor exit node.
          - IP flagged on multiple blacklists.
          - Suspicious login.
      
      

With Trunc, this enriched information immediately flags potential risks, such as the use of a Tor exit node and the mismatch between the user’s usual location and the login location. What would have been buried in noise is now clear and actionable.

Efficiency Through Categorization


Trunc’s default rules automatically classify logs into actionable categories, simplifying investigations for administrators. With a single query—such as:

      category:authentication_success AND category:tor_connection
      
You can instantly pinpoint high-risk events without sifting through thousands of irrelevant entries.
