Mobile App Penetration Testing Services

Mobile apps are an important way for businesses to interact with their customers, employees, and partners. Whenever your app processes payments, stores sensitive data, offers healthcare services, or supports your operations, it becomes a target for cybercriminals.

Mobile apps face different security challenges than web apps. Sensitive data might be stored on the device, APIs send information over public networks, authentication tokens can be exposed, and poor coding can let attackers bypass security or access data they shouldn’t.

At Tanner Security, we help businesses find and fix security issues in their mobile apps before attackers can exploit them. Our experienced testers check iOS, Android, and cross-platform apps using both automated tools and hands-on testing to mimic real-world attacks.

If you’re getting ready to launch, need to meet customer or regulatory requirements, or want to check the security of an existing app, our team offers independent assessments to help lower risk and boost your app’s security.

Mobile apps often handle a company’s most sensitive data, including customer records, payment information, healthcare data, login details, business secrets, and personal information.

Attackers target mobile apps because weaknesses can give them direct access to backend systems or to valuable customer data.

Even small security issues, such as weak data storage, poor authentication, or unprotected APIs, can lead to significant financial losses, fines, damage to your reputation, and loss of customer trust.

Regular penetration testing helps you find these risks before attackers do and shows your commitment to protecting users and sensitive data.

We start every project by learning about your app’s structure, business goals, technology, user flows, authentication, and deployment.

Our team of consultants evaluate client-side security, local data storage, authentication, session management, API communications, encryption, certificate validation, authorization controls, business logic, input validation, backend integrations, third-party libraries, and application resilience against common attack techniques.

We use both automated tools and thorough manual checks, since many serious vulnerabilities can’t be found by automated scans alone.

Upon completion, clients receive a detailed technical report describing identified vulnerabilities, business impact, proof-of-concept evidence, remediation guidance, and executive-level summaries that help leadership prioritize corrective actions.

Every application presents unique risks, but our assessments commonly identify insecure authentication, weak authorization controls, exposed APIs, insecure local data storage, improper certificate validation, insufficient encryption, insecure session management, hardcoded credentials, sensitive information disclosure, insecure third-party components, business logic flaws, and weaknesses associated with the OWASP Mobile Application Security Testing Guide (MASTG).

Rather than simply listing vulnerabilities, we explain how each issue affects your business and prioritize remediation based on exploitability and potential business impact.

Many successful attacks on mobile apps happen because of insecure APIs, not just problems in the app itself.

Even a well-built mobile app can leak sensitive data if its backend APIs don’t properly check users, validate requests, enforce permissions, or protect information.

Our penetration tests assess how your app and its APIs work together to make sure security controls are strong across your entire system.

Regular mobile app penetration testing helps you build secure software and meet customer security needs at every stage of development.

Testing also supports many cybersecurity and compliance initiatives, including ISO 27001, SOC 2, HIPAA, PCI DSS, CMMC, and the OWASP Application Security Verification Standard (ASVS). While penetration testing alone does not achieve compliance, it provides valuable evidence that security controls are being independently evaluated.

Adding penetration testing to your development process lets you find problems sooner, fix them for less, and improve software quality before launch.

An independent assessment provides an unbiased view of how well your app’s security works. Many businesses use these insights to improve authentication, strengthen API security, protect sensitive data, check encryption, fix business logic issues, and lower the risk of attacks.

Independent testing can also increase customer confidence, speed up enterprise sales, and show that you take application security seriously.

At Tanner Security Consultants, we are the Mobile Application Penetration Testing advisors who stand at the forefront of protecting your future. Trusted by Fortune 500 companies, dynamic SaaS enterprises, and cherished family-run businesses, we embody cybersecurity prowess. We empower companies with extensive expertise in mobile application penetration testing, new technology, and innovative strategies to fortify their security programs and protect their digital infrastructure.

We bring together experts in application security, penetration testing, secure software development, cloud security, governance, compliance, and risk management. It does so by manually evaluating how attackers could exploit real-world weaknesses. Every engagement focuses on helping your business understand risk, prioritize remediation, and strengthen application security before vulnerabilities become incidents.

If you’re launching a new mobile app, getting ready for a customer review, or checking an existing platform, our team offers practical security testing that brings real business value.

Mobile app security is just one part of protecting your software. Many businesses add additional security assessments to mobile testing to gain a comprehensive view of their risks.

Our related services include:

• Web Application Penetration Testing to identify vulnerabilities in customer-facing and internal web applications.
• Custom Application Penetration Testing for proprietary software, APIs, and business-critical platforms.
• API Penetration Testing to validate authentication, authorization, input validation, and business logic within REST and GraphQL APIs.
• Cloud Risk Assessment Services for AWS, Microsoft Azure, Microsoft 365, and hybrid cloud environments.
• External Network Penetration Testing to evaluate internet-facing infrastructure.
• Internal Network Penetration Testing to identify risks inside your corporate environment.
• Governance, Risk, and Compliance (GRC) consulting to align application security with regulatory and contractual requirements.

Together, these services give you a complete way to lower cyber risk and improve software security at every stage of development.

Although these terms are often used interchangeably, they are not identical.

A Mobile Application Security Assessment is a broad review of an application’s overall security posture. It may include architecture reviews, secure code analysis, configuration reviews, compliance evaluations, threat modeling, and development process assessments.

A Mobile Application Penetration Test focuses on actively exploiting vulnerabilities within the application and its supporting APIs to determine whether an attacker could gain unauthorized access, steal sensitive information, bypass security controls, or compromise backend systems.

You can think of a security assessment like a full medical checkup that finds health risks, while a penetration test is like a stress test that shows how the body handles real-world challenges.

Many businesses perform both because they provide complementary insights. Together, they help leadership. Many businesses do both because they offer different but helpful insights. Together, they help leaders build better security, lower risk, boost customer trust, and better protect the data behind today’s mobile experiences.
