Fact-Check: According to Canalys, 2020 reported a record number of data breaches. The numbers reported were higher than the previous 15 years despite a 10% increase in cyber security spending. Over 101 billion records across the globe were claimed to be compromised last year alone. A major reason for this could be attributed to the abrupt shift to remote work due to the Covid-19 Pandemic.

Frequently Asked Questions

Q #1) Who competes with Qualys?

Answer: Qualys has been around for a while now. At that time, it has gone head to head with many competitors. Here are some of its most known competitors:

  1. Indusface
  2. Invicti (formerly Netsparker)
  3. Acunetix
  4. Intruder
  5. Zscaler
  6. Veracode

Q #2) Why Qualys is used?

Answer: Qualys is a cloud-based web application scanner that is known for proactively locating and assessing vulnerabilities in an application or website. It automatically classifies vulnerabilities based on the severity of their threat so security teams can prioritize their remedial response.

Qualys can perform deep scans on IoT services and mobile applications to identify both known and undocumented vulnerabilities with actionable insights on how to deal with them.

Q #3) Is Qualys open source?

Answer: Qualys is a provider of multiple commercial web application scanning and security testing tools. It has recently released its own open-source web application fingerprinting tool called BlindElephant.

BlindElephant can identify application and plugin versions of them via static files. This new version features a powerful fingerprinting engine that is incredibly fast and accurate.

Q #4) Is Qualys a DAST?

Answer: Yes, Qualys is a good Dynamic Application Security Testing tool. It can run security tests on an application for vulnerabilities while the application is still running.

With DAST, you are testing the application from the outside in. So a developer isn’t aware of the framework with which the application was built. This method also means that the vulnerability will be identified at the end of a software’s development lifecycle.

Q #5) What does API stand for and does Qualys perform scans on APIs?

Answer: Yes, Qualys can examine APIs for vulnerabilities, mainly mobile APIs. API, also known as Application Programming Interface, refers to a set of protocols and definitions that are required to build and integrate an application software. APIs help your product or service communicate with other products or services without being aware of how they were implemented.
