11 BEST AppSpider Alternatives [2023 REVISED LIST]

Review and comparison of the top AppSpider alternatives to suggest the best AppSpider competitors available in the application security tester market:

When it comes to application security testing, one can argue that none share the pedigree that Rapid 7’s AppSpider brings to the table. AppSpider is a powerful and advanced web application security tester that can accurately scan APIs, SPAs, and mobile applications without any hassle.

The app constantly gathers information, and that indeed makes it considerably effective in testing ever-evolving apps for vulnerabilities. AppSpider’s utilization of dynamic application security testing makes it capable of crawling even through the most complex and modern apps.

It can easily identify risks affecting these apps and provide you with the insights required to remediate them immediately. AppSpider can detect and remediate risks in the early stages of a software’s development lifecycle.

Despite its impressive functionality, AppSpider has received a lot of flak for its complex UI. The UI can make the tool difficult to operate and navigate. Fortunately, AppSpider isn’t the only web application security testing tool out there.

Frequently Asked Questions

Q #1) What Does AppSpider Do?

Answer: AppSpider utilizes dynamic application security testing to scan mobile apps, APIs, SPAs, etc. for risks and also provides insights to help security teams remediate the threat.

The platform is constantly evolving and is capable of identifying weaknesses in both modern and complex applications without any hassle. Its black-box testing capabilities also help AppSpider detect issues in the early stages of the SDLC.

Q #2) Is AppSpider Free?

Answer: AppSpider is a powerful application testing product from the house of Rapid 7. Just like every other security testing product from Rapid 7, AppSpider isn’t free. AppSpider can be very expensive. As such, only large enterprises are recommended to use the platform.

However, AppSpider does offer a free trial to its clients wherein you can test the features and automation of the tool at no cost for a limited period.

Q #3) What is the Principal Difference between DAST and SAST?

Answer: SAST and DAST differ in two key areas of security testing. Both find different types of vulnerabilities and are most effective at different stages of the SDLC. SAST is known as a white box method of testing. It analyzes code to find flaws in the software. SAST is always performed early on all types of files that contain the source code.

DAST, on the other hand, is a black-box testing method that analyzes a running application to find weaknesses that an attacker could potentially exploit. This type of testing mimics the approach of a hacker to find vulnerabilities.

Q #4) What is Broken Session Management?

Answer: Broken Session Management is a critical security vulnerability that allows an online attacker to forge session data or steal a user’s login data to gain unauthorized access to websites. This security threat is listed in the OWASP Top 10 list of common vulnerabilities. As such, it should be taken seriously.
