Attackers target web applications, and that trend shows no signs of slowing. According to the 2018 Verizon Data Breach Investigations Report, more data breaches began with a web application compromise than any other way. Between SQL injection, Cross-site Scripting (XSS), file inclusion, and remote code execution vulnerabilities, attackers are looking for any possible way to penetrate your web application and get to the valuable data stored on your web servers and networks.

To keep your business and cardholder data safe, you must assess the security posture of your web applications regularly. You need an online vulnerability scanner that reliably identifies web vulnerabilities from the OWASP Top 10 and beyond, seamlessly updates security tests to identify the latest security vulnerabilities, and provides clear, actionable advice.

With the online Netsparker web application security solution, it has never been easier to streamline web vulnerability management. Get started for free.

Save Time and Money with Proof-Based ScanningTM

Save time and money when you test websites with Netsparker's online vulnerability scanner. See this for yourself during your 15-day free trial.

Traditional automated web security scanners report a lot of false positives. They require security professionals or developers to spend days manually verifying results before knowing if a vulnerability is real or not. Apart from being a tedious and time consuming, such process requires a lot of technical expertise.

Our exclusive Proof-Based ScanningTM technology saves you time by providing proof of exploit. For example, whenever the security scanner exploits a SQL injection, command injection, file inclusion, or remote code evaluation attack, the Netsparker scan report will show what HTTP parameters were sent, the payload, and what data was obtained by exploiting the security vulnerability.

These dead accurate results save time throughout the remediation process. Analysts are quickly aware of exploitable security vulnerabilities. IT security teams can provide clear justification to management, citing exactly what data is at risk behind the web application. And, developers know which parameter, HTTP request or SQL query exploited the problem, helping them identify and fix the vulnerable code quickly.

Easy, Secure Online Access for Teams

The cloud edition of the Netsparker security scanner also helps you save time in collecting and sharing scan results. Authorized users can log into the TLS encrypted multi-user portal to access web application scan configurations and security scan results.

When a new application requires testing or a new vulnerability arises, launching an online web vulnerability scan is easy to do from the portal. After the vulnerability assessment, members of the IT security team can quickly see the findings and proofs of exploit. Proof-Based ScanningTM results are available to authorized team members through the portal. Web vulnerability scans can also be automatically triggered when the Netsparker vulnerability scanner is integrated in your SDLC and DevOps environments.
