Invicti Web Application Security Scanner – the only solution that delivers automatic verification of vulnerabilities with Proof-Based Scanning™.

Penetration testing has become an essential part of any modern strategy to protect web applications. Pen-testing solutions are preferable to free or open-source ones to prevent attacks on critical APIs and web apps.

The nature of cyberattacks is constantly evolving. For this reason, companies, government agencies, and other organizations are implementing increasingly sophisticated cybersecurity techniques to protect their web applications from cyber threats.

Among these techniques is penetration testing, which, given its growing popularity, is on track to become a $4.5 billion market by 2025 as predicted by the consulting firm Markets and Markets.

What are penetration tests?

Penetration tests are simulations of cyberattacks against a computer system, a network, a site, or an application.

Typically, pen-tests are carried out by trained security testers who try to breach an organization’s security systems to identify their weaknesses, although there are also automated tests that reduce testing times and costs.

The objective of these tests – whether automated or manual – is to detect vulnerabilities that cybercriminals could exploit to perpetrate their crimes to eliminate them before an attack occurs.

Pen-testing offers several important benefits that make it so popular. But they also have a few downsides.

Benefits and Disadvantages of Penetration Testing

The main benefit of penetration tests is identifying vulnerabilities and the information about them to eliminate them.

In addition, the results of pen tests allow for increasing the knowledge of the digital assets (mainly web applications) that are sought to be protected. As a positive side effect, increased application awareness and protection help improve your customers’ trust.

Pen-testing practice also has its downsides. One of the most relevant is that the cost of making a mistake when doing such tests can be very high. The tests can also have negative ethical implications since the activity of criminals who lack all ethics is being simulated.

Many free and open-source security tools are suitable for small or starter sites. When doing manual penetration testing, the cost depends on the skills of the testers. To put it short, manual testing should be expensive to be good. If penetration testing is run as part of a software development process, running it manually slows the development cycle.

To avoid risks in business web applications, premium penetration testing solutions are preferable, as they offer additional benefits, such as detailed reports, specialized support, and recommendations for troubleshooting.

Read on to learn about the top premium penetration testing solutions for your critical web applications.


Penetration testing solutions such as the Invicti Vulnerability Scanner empower companies to scan thousands of web applications and APIs for vulnerabilities in a matter of hours.

They can also be embedded within a software development life cycle (SDLC) to periodically scan web applications for vulnerabilities that may appear with each code change. This prevents security breaches from making their way into live environments.

An important aspect of penetration testing tools is coverage, which means that the tool must cover all possible alternatives of a web application or a web API. If there is a vulnerable parameter in an API or an application, and that parameter is not tested, the vulnerability will not be detected.

Invicti’s web application security scanner excels at offering the widest coverage possible so that no vulnerabilities go unnoticed.

Invicti uses a Chrome-based crawling engine that can interpret and crawl any web application, regardless of whether it is legacy or next-generation, as long as it is available through the HTTP and HTTPS protocols.

Invicti’s crawling engine supports JavaScript and can crawl HTML 5, Web 2.0, Java, Single Page Applications, as well as any application that uses JavaScript frameworks such as AngularJS or React.
