Custonis – Security Exposure Scanner

Description

Custonis detects publicly exposed files that should never be accessible on the internet.

Many WordPress websites unintentionally expose sensitive files such as:

  • database backups (.sql, .zip)
  • exported user or customer data
  • configuration files (.env, wp-config backups)
  • debug logs and error logs
  • development leftovers

These files are actively targeted by bots and attackers because they may expose:

  • database credentials
  • API keys
  • user data
  • internal system information

Why Custonis?

Most security plugins focus on firewalls, malware or login protection.

Custonis focuses on a different but critical attack surface:

👉 Public file exposure

It helps you identify risks that are often overlooked and complements traditional security plugins.

✔ Severity classification (Critical / Elevated / Low)
✔ Security score calculation
✔ Risk level indicator
✔ Exposure age detection
✔ Detailed findings dashboard
✔ Scan history chart

✔ 100% local scanning (no external API calls)
