Unpacking the Power of Comprehensive Web Vulnerability Scanners

Organizations manage a vast array of increasingly complex web applications, each a potential target for cybercriminals relentlessly searching for vulnerabilities they often find. This is a major issue because these applications, often repositories for sensitive data, including personal identification, payment details, and health information, present a substantial security challenge. The stakes are high, as any breach could lead to devastating financial and reputational damage.

Research has shown that 70% of web applications have security gaps, many of which could easily have been caught and remedied before they went live. The problem lies in having the right technologies and tooling to detect these problems effectively without collecting a pile of data. Many of these are false positives or overlook vulnerabilities because application scanners do not have the capability to see every aspect of the web app.

Single-purpose vulnerability scanners lack depth and visibility, limiting the amount, variety, and volume of vulnerabilities you can see. A comprehensive web vulnerability scanner leverages multiple scanners and testing tools under one umbrella to increase the range of detection and customize scanning options to meet the application’s needs. These scanners detect a wide array of vulnerabilities, including common injection attacks like SQL injections and cross site scripting (XSS), as well as more complex security loopholes such as broken authentication or broken access controls. They simulate user and attack behaviors to test the application’s responses to various inputs and conditions. This allows organizations to understand where their web applications might be vulnerable to attack before malicious parties exploit these weaknesses.

This variety of scanners is more than just a detective device. It also helps developers by integrating seamlessly with development tools, supporting continuous integration/continuous deployment (CI/CD) pipelines to ensure ongoing security assessment throughout the software development lifecycle. It provides detailed reports that prioritize vulnerabilities based on severity, offer remediation steps, and help maintain compliance with relevant regulations like GDPR and HIPAA.

A comprehensive web vulnerability scanner offers deep visibility into the various layers of a web application by combining multiple testing approaches: Static Application Security Testing (SAST), Dynamic Application Security Testing (DAST), API analysis, or external attack surface management (EASM). Most scanners only offer a single testing approach. Those that offer more than one are more comprehensive and can be combined with others when necessary.

SAST examines source code for vulnerabilities, providing early detection of potential issues. However, it doesn’t catch runtime problems, which is where DAST steps in, dynamically testing the application in production to uncover vulnerabilities that only appear during execution. Meanwhile, API analysis targets the interfaces and communications that might be overlooked by SAST and DAST, ensuring a thorough examination of both internal and external data exchanges. EASM helps organizations discover assets, helping reduce their attack surface by extending protection to previously unidentified areas.

Automation with these tools also helps organizations meet compliance mandates. Integrating the CI/CD pipeline ensures that testing happens every time rather than when developers have time or remember to run a scan. Teams identify issues consistently and systematically, bypassing the reliance on manual initiation, which could lead to skipped tests or overlooked vulnerabilities. It identifies security gaps as development occurs, allowing teams to remediate earlier in the development process rather than creating an immense backlog of technical debt to manage later.

Modern web apps are no longer simple static pages. Instead, they are dynamic, interactive platforms that integrate with various APIs and operate on complex architectures, including single-page applications (SPAs) and microservices. This has increased the complexity of web applications and the development processes necessary to support them, driving the need for more advanced scanners.

This intricacy significantly increases the attack surface, making it difficult to manually identify and manage security threats. A more comprehensive scanner becomes necessary as it can automatically detect a wide range of vulnerabilities across all layers of an application, ensuring nothing is overlooked.

Given this complexity, automated and thorough vulnerability scanning is a must. Attackers know that complexity increases the likelihood of a vulnerability being present and have adapted their tactics and techniques to detect and exploit them. Using a comprehensive scanner, even the most complex applications can be analyzed holistically, reviewing every layer to detect security weaknesses. This data allows developers and security teams to remediate these weaknesses before attackers get a chance to leverage them, significantly reducing the risk of an attack being successful.

Implementing a comprehensive web vulnerability scanner involves navigating several key technical, operational, and strategic challenges. The complexity of setting up and maintaining such scanners requires a deep understanding of the technology and the specific security needs of modern web applications. These scanners must integrate seamlessly into existing CI/CD pipelines and development workflows, ensuring they augment rather than disrupt the development process.

On the operational front, these scanners are resource-intensive, necessitating significant computational power, which can lead to system slowdowns if not appropriately managed. The challenge of balancing scanner sensitivity to minimize false positives and negatives is critical to maintaining team efficiency and focus on actual application vulnerabilities. Moreover, the rapid evolution of cyber threats demands that these scanners be regularly updated to detect new vulnerabilities, requiring a proactive approach to scanner management and updates. This continuous adaptation is essential to keep pace with the advancing landscape of web security threats.

Unlike many vulnerability scanning tools that focus on a single capability, Probely offers a comprehensive functionality to investigate even the most complex web applications. Probely combines DAST with API scanning and EASM (External Attack Surface Management) to deliver a solution that helps organizations better understand their attack surface and detect over 3000 vulnerability types, including critical ones such as XSS and SQL injections. These scanners support authenticated scans as well, allowing a deeper and more meaningful assessment of functionality in production, even in the most restrictive environments. When used in conjunction with SAST tooling, which most organizations have, Probely helps build a comprehensive vulnerability assessment.

Probely is built to empower and enable developers and easily integrates into their workflows to streamline the development and assessment process. It helps create automated and continuous security assessments that boost efficiency and fortify their applications throughout their lifecycle, helping ensure applications can meet stringent compliance mandates. Probely goes beyond just showing vulnerabilities, it provides actionable insights and educational material, helping developers learn from their mistakes, so they avoid repeating them in the future.
