Simple, affordable app scanning

Developed with insights from nearly 10,000 penetration tests, the Defense.com® web app scanner strengthens your security strategy by complementing traditional pen testing. It continuously tests your applications for vulnerabilities—without the added cost or complexity of one-off testing projects.

Compliance as standard

Assess your applications against the OWASP 10 to meet the requirements of PCI DSS, ISO27001, DORA and more.

Easily manage threats

Prioritise and track your remediation efforts with ease using our easy-to-use threat management interface.

Comprehensive vulnerability detection

Our app scanner is designed to identify a wide range of security vulnerabilities, ensuring your web applications are protected against the most common and dangerous threats.

SQL Injection

Allows attackers to execute malicious SQL queries, potentially compromising your database and exposing sensitive information.

Cross-Site Scripting (XSS)

XSS enables attackers to inject malicious scripts into web pages, which can lead to data theft, session hijacking, or defacement of your site.

Cross-Site Request Forgery (CSRF)

CSRF tricks users into performing actions they didn’t intend, such as changing account details or making unauthorised transactions.

Insecure Direct Object References (IDOR)

IDOR occurs when an application exposes internal objects, allowing attackers to access unauthorised data or functionality.

Security Misconfigurations

Misconfigured security settings can leave your application vulnerable to attacks, such as default credentials or unnecessary services running.

Sensitive Data Exposure

Inadequate protection of sensitive data, like credit card numbers or personal information, making it accessible to attackers.

Broken Authentication

Flaws in authentication mechanisms can allow attackers to gain unauthorised access to user accounts or sensitive areas of your application.

XML External Entities (XXE)

XXE vulnerabilities enable attackers to exploit XML parsers, potentially leading to data exfiltration, server-side request forgery, or denial of service.
