Have you ever set up a cybersecurity tool, fired it up on your localhost, and felt that rush of excitement just before the results come in? That’s exactly how it felt when I got WebCheck running on my system, and the insights were worth every second.

Here’s how it went down: I recently installed WebCheck, an open-source web security tool, on my Casa OS running on Zorin OS through the terminal. I containerized it with Docker, pulling the image and firing up the app on my localhost. Once it was up and running at http://192.168.1.196:13000/, it was game on.

I needed a target to test out WebCheck’s capabilities, and I thought, why not go big? So, I picked visitmalawi.mw. Little did I know, I was about to uncover a mix of successes and failures that painted a pretty intriguing picture.

The Setup: Making It Happen

Setting up WebCheck wasn’t just a random whim. It was a calculated move to boost my hands-on experience with cybersecurity tools. Here’s how I got it done:

  • Step 1: Casa OS Installation

  • Step 2: Docker Configuration

  • Step 3: Firing Up WebCheck

  • Step 4: Choosing the Target

  • Step 5: Vulnerability Scan Results


The Results:

In just 26 seconds, WebCheck hit me with a full breakdown of the website’s security status. It was a wild ride, and here’s the verdict:

✅ Successes: What Worked Well

  • SSL and TLS Security Configuration:

  • DNS Security and Firewall:

  • HTTP Security Headers and HSTS:

  • Social Tags and Threat Detection:

  • TLS Cipher Suites:

❌ Failures: Where It Fell Short

  • IP Retrieval and Location:

  • Tech-Stack Identification:

  • Server Information and Mail Configuration:

  • Carbon Emission Check:

  • Screenshot Capture:

Key Takeaways: What I Learned This experiment wasn’t just about running a tool—it was about analyzing the output and interpreting what went wrong and why. Here’s what I took away from this run:
