Invicti, formerly Netsparker, vs Nessus

Network security should be part of your cybersecurity strategy, but that is only one part of the game. You also need a web vulnerability scanner that can scan web applications and identify security flaws in them.

I’ve long been an advocate of Invicti, formerly Netsparker, because I believe it’s the easiest on-demand, do it yourself dynamic security analysis tool.


If you are considering security tools, the first thing you need to ask yourself is — what are you planning to test? According to the latest Verizon Data Breach Investigation Report, flaws in web applications are the most common cause of data breaches. In order to protect against these attacks, you need a web vulnerability scanner, a purposely-built software that assesses the security of web applications. You need Invicti, formerly Netsparker.

Different Scanners Serve Different Purposes

You may be familiar with Tenable Nessus already. Network vulnerability scanners like Nessus, Qualys, and Rapid7 Nexpose serve an important purpose in a security testing program, however they do not provide a complete vulnerability picture because they mostly focus on network security. Network level testing is definitely required, but it does not provide a deep analysis of the web application security that you need.

What You May Be Missing

Network scanners can perform a few checks related to a web presence, such as identifying vulnerable versions of web servers or known open source platforms. But, a web application scanner is specifically equipped to map out all web pages and user inputs. Unlike a network scanner, it offers thorough vulnerability tests for security vulnerabilities such as cross-site scripting (XSS), SQL injectionremote file inclusion, and other critical issues, including those listed in the OWASP Top Ten list of most critical web security flaws.

Why Choose Invicti, formerly Netsparker

You know you need a web application vulnerability scanner. The market is crowded with commercial options such as Invicti, formerly Netsparker, Webinspect, IBM Appscan, Burp Suite, and as well as open source web security scanners such as Zed Attack Proxy (ZAP) and w3af. How do you choose?

You need a scanner that gives you accurate, actionable scan results for the web applications you have now, and in the future. Here is why Invicti, formerly Netsparker, is the right choice.

Platform Independence

Invicti,formerly Netsparker, is platform-independent. It does not matter whether your web server resides on a Microsoft Windows server, Linux, Unix, or another platform, or whether the underlying operating system is bare-metal or a virtual machine. From legacy web applications to modern HTML 5, it finds all possible attack surfaces and tests them thoroughly for real vulnerabilities that attackers are trying to exploit. Invicti,formerly Netsparker, also scans the web server for security flaws.

Configure and Scale

Our web security solution adapts and scales. Whether you have one application or thousands, defining the scope of a scan is simple in Invicti, formerly Netsparker. And, you can configure a scan to run against the broad spectrum of security vulnerabilities, or run a scan to perform vulnerability detection against just one or two bleeding-edge security flaws that may be dominating the threat landscape.

Unmatched Accuracy

Invicti’s, formerly Netsparker’s, Proof Based Scanning™ gets your security team from scan results to a more secure web presence faster.

Our scanner gives you dead accurate results: in a web vulnerability scanners comparison (DAST) by independent researcher Shay Chen, Invicti, formerly Netsparker, identified all the security vulnerabilities in the benchmark test cases, with no false positives. You can trust the results to give you a detailed picture of the attack surface, and your security analysts no longer have to spend hours manually verifying false positives instead of moving on to more valuable tasks.

Proof of Exploit

Invicti’s, formerly Netsparker’s, reporting provides not only vulnerability detection, but true proof of exploit. Security analysts can open the result in the console, see at a glance what text in the HTTP request exploited the vulnerability, and view exactly what was compromised as a result.

This gives the security team confidence in the scan results and makes it easier for them to justify security efforts to management. It also helps software development teams hone in quickly on the vulnerable source code and fits perfectly in a secure SDLC to take guesswork out of vulnerability remediations.
