Webclei, a free online web vulnerability scanner, is gaining traction among cybersecurity professionals and developers for its robust capabilities in identifying security flaws in websites and web applications. Unlike many free tools that offer limited functionality, Webclei provides comprehensive scanning features typically found in premium solutions.
At its core, Webclei operates on a template-based system written in YAML, allowing it to systematically test websites against a wide array of known security issues. These templates are community-maintained and regularly updated, ensuring the scanner remains effective against emerging threats. The tool supports multiple protocols, including HTTP, DNS, and TCP, making it versatile for various security testing scenarios.
One of Webclei's standout features is its concurrent execution capability, enabling it to perform multiple checks simultaneously. This optimization significantly reduces scanning time without compromising accuracy. Users can initiate a scan by simply entering their website URL, selecting specific template categories if desired, and choosing the severity levels of vulnerabilities they wish to detect. The scanner then provides detailed results, categorizing findings by severity—Critical, High, Medium, Low, and Informational.

In practical applications, Webclei has demonstrated its efficacy. For instance, a scan conducted on a government website revealed 31 vulnerabilities, including six medium-severity issues and 25 informational findings. Notably, the scan identified several Roundcube log disclosure vulnerabilities, which could potentially expose sensitive email server information, and missing security headers, highlighting areas for security enhancement.
Webclei excels in detecting a range of common vulnerabilities, such as missing security headers, SSL/TLS configuration issues, information disclosure, cross-site scripting , SQL injection flaws, and server misconfigurations. Its ability to identify these issues makes it a valuable tool for website owners seeking to bolster their security posture without incurring significant costs.
While Webclei offers substantial benefits, users must exercise caution and adhere to legal and ethical standards. The tool should only be used to scan websites that the user owns or has explicit permission to test. Unauthorized scanning of third-party websites can lead to legal repercussions. Additionally, users are advised to respect rate limits to avoid overwhelming servers and to follow responsible disclosure practices when vulnerabilities are discovered.
In comparison to other vulnerability scanners, Webclei holds its own. Paid solutions like Nessus or Qualys offer more extensive features but may be excessive for small to medium-sized websites. Other free tools, such as OWASP ZAP, require installation and a certain level of technical knowledge, whereas Webclei operates directly in the browser with no setup required. Manual security testing, while thorough, is time-consuming, and Webclei automates much of this process, allowing users to focus on more complex security analyses.
For users seeking to integrate Webclei into their security workflows, the tool offers advanced techniques, including template filtering to focus on specific vulnerability types, custom severity filtering, and regular monitoring to catch new vulnerabilities as websites evolve. By incorporating Webclei into development and deployment processes, organizations can proactively identify and address security issues, enhancing their overall cybersecurity resilience.
