What is Mobile and Web Application Security?

Mobile and web applications are crucial to making data available to employees, customers and partners. But these systems that simplifydata availability within the business are attractive targets for cybercriminals.These highly connected applications draw data numerous internal resources and databases. And if hackers can compromise your applications, they can use this foothold to exploit other network resources, or to steal IP and client data.Identifying and addressing vulnerabilities in your web-enabled applications is essential to raising the standard of security within your operations.

Why Test Mobile and Web Application Security?


Reduce attack potential

Identifying – and resolving – issues with your web applications and mobile apps will strengthen the overall security of your network. Reducing the number of available entry points will make your business much harder to attack.


Identify outdated APIs

Your web applications will use a series of APIs to link disparate services. Outdated APIs can be exploited to gain access to underlying data and credentials. Fidus will analyse the APIs in use, advising where code updates are required to address these vulnerabilities.


Ascertain adherence to OWASP Top 10

Web and Mobile applications will be tested against the OWASP Top 10 methodology to ascertain adherence alongside using Fidus’ own internal methodologies.


Identify insecure services

Third party applications may connect to external data sets to provide additional functionality or context. Each of these services needs to be tested to confirm data is properly secured at every point.


Address unpatched apps, frameworks and mobile operating systems

Third party apps and software also need to be regularly updated to resolve potential exploits. Again, the Fidus mobile and web application testing service will analyse all of your web-enabled assets and mobile apps to identify instances where updates are required.

Our Approach

Environment research

Our security consultants will first inventory all of your applications. They will then research each, to obtain the latest threat intelligence for use in planning our security tests.

Damage modelling

To better understand the severity of the problems identified, our consultants will carry out an extended series of tests. We will (harmlessly!) exploit each vulnerability to assess the degree of risk they present.

Application vulnerability testing

Using a combination of automated tools and our extensive knowledge of cybersecurity, we probe each of your applications for vulnerabilities. We’ll test for common exploits like SQL-injection and cross-site scripting (XSS), as well as more advanced vulnerabilities such as application logic flaws and session management flows.

Plain English reporting

Cybersecurity complicated – but the results of our tests don’t have to be. Our consultants will present the results of our web and mobileapplication tests in easy-to-understand reports. This ensure you can make informed strategic decisions more quickly and easily.
