Custom Application Penetration Testing Services

Secure Your Custom Applications with a Pen Test

At Tanner Security Consultants, we understand that custom-built applications present unique security challenges. Our Custom Web Application Pen Testing services will identify vulnerabilities specific to your custom applications. We specialize in OWASP Penetration Tests to test your web applications against the most critical security risks.

Why Custom Application Penetration Testing is Essential

  1. Identify Unique Vulnerabilities: Custom applications often have specific security weaknesses that off-the-shelf solutions do not address. Our testing uncovers these hidden vulnerabilities.
  2. Mitigate Risks: Reduce the risk of data breaches, unauthorized access, and other security incidents that can lead to significant financial and reputational damage.
  3. Ensure Compliance: Meet industry regulations and standards that mandate regular security assessments for custom applications.
  4. Enhance Security Posture: Strengthen your cybersecurity posture with targeted testing and expert recommendations tailored to your application.

Our Custom Application Penetration Testing Process

  • Initial Consultation: We start by understanding your application’s architecture and specific security concerns.
  • Vulnerability Assessment: Our team uses advanced tools and techniques to identify potential security weaknesses in your custom application.
  • Exploitation Testing: We simulate real-world attacks to evaluate the impact of identified vulnerabilities.
  • Detailed Reporting: Receive comprehensive reports detailing vulnerabilities, their impact, and actionable remediation steps.
  • Remediation Support: We provide ongoing support to help you implement security measures and verify their effectiveness.
  • Final Review: Conduct a final review to ensure all issues have been addressed and your application is secure.

Our Penetration Test Process

  • Initial Assessment: We review your web applications against the OWASP standards. Review our guide to web application pen testing.
  • Vulnerability Identification: Our team uses advanced tools and methodologies to detect security weaknesses.
  • Exploitation Testing: We attempt to exploit identified vulnerabilities to assess their potential impact.
  • Remediation Guidance: Provide actionable steps to address vulnerabilities and strengthen security controls.
  • Final Review: We conduct a final review to ensure all issues have been resolved and your web applications are secure.

Our Pen Test Approach:

We follow a systematic approach to ensure a thorough and effective penetration test engagement:

  1. Planning and Scoping: Our first step is to collaborate closely with your team to understand your unique requirements, goals, and specific areas of concern. We define the scope of the engagement, including the systems, applications, networks, and assets.
  2. Reconnaissance and Information Gathering: Using passive and active techniques, we gather information about your organization’s digital footprint, identifying potential entry points and attack vectors that malicious actors could exploit.
  3. Vulnerability Assessment: We comprehensively assess your infrastructure, systems, and applications to identify exploitable vulnerabilities and misconfigurations. These tests include both automated scanning and manual analysis by our experienced security professionals.
  4. Exploitation and Penetration: Our skilled penetration testers leverage their expertise and knowledge to attempt attack vectors and exploit identified vulnerabilities. We simulate real-world scenarios to determine how much your systems are susceptible to compromise.
  5. Post-Exploitation and Privilege Escalation: If we successfully penetrate your web application, we will attempt to escalate privileges to assess the potential impact of a successful attack. This step helps identify vulnerabilities in your privilege management and access controls.
  6. Reporting and Recommendations: Following the testing phase, we provide you with a comprehensive report that outlines our findings, including detailed descriptions of vulnerabilities, their severity, and potential impact. We prioritize the identified risks and offer clear, actionable recommendations to remediate the vulnerabilities and strengthen the security posture.

How Web Application Penetration Testing Works

Our process begins by identifying the application’s scope, including both authenticated and unauthenticated areas. We then perform detailed testing using both manual techniques and specialized tools to uncover vulnerabilities.

Testing includes authentication mechanisms, session management, input handling, API endpoints, and business logic. Once testing is complete, we provide a report detailing each finding, the associated risk, and clear remediation steps.

Who Needs Web Application Penetration Testing Services?

Companies that rely on web applications to deliver services, process transactions, or store sensitive data benefit from regular testing. This includes SaaS companies, financial service providers, healthcare, small to medium sized businesses, and any business with customer-facing applications.

Companies preparing for compliance requirements and require a PCI consultant or  are trying to get SOC 2 certified, also require application security testing to validate controls.

Cost of Web Application Penetration Testing

The cost of web application penetration testing services depends on application size, complexity, and the number of user roles or interfaces tested. Smaller applications may require limited testing and can cost as little as $8,000-$15,000, while complex platforms with multiple integrations require deeper analysis and can cost $20,000-$75,000.

Tanner Security provides clearly scoped pricing based on your environment and testing requirements.

Frequently Asked Questions – Web Application Penetration Testing Services

Web application penetration testing services include a comprehensive evaluation of your application’s security controls, authentication mechanisms, session management, input validation, and access controls. Testing also covers APIs, user roles, and business logic to identify vulnerabilities that could be exploited by attackers.

A vulnerability scan uses automated tools to identify potential security issues, while web application penetration testing involves manual testing to actively exploit those issues. Penetration testing provides a deeper understanding of risk by showing how vulnerabilities can be chained together and used in real-world attacks.

Web applications should be tested at least once per year. Additional testing is recommended after major updates, new feature releases, infrastructure changes, or when integrating third-party services. Regular testing helps ensure new vulnerabilities are identified and addressed quickly.

Common vulnerabilities include SQL injection, cross-site scripting (XSS), broken authentication, insecure direct object references, and misconfigured access controls. Many applications also contain logic flaws that cannot be detected through automated scanning alone.

Yes. Testing includes both unauthenticated (external user) and authenticated (logged-in user) areas. Authenticated testing is critical because it often reveals deeper vulnerabilities, including privilege escalation and data exposure risks.

Testing is performed in a controlled manner designed to minimize disruption. While certain techniques simulate real attack behavior, our team works closely with your organization to avoid impacting production systems or user experience.

The timeline depends on the size and complexity of the application. Most engagements are completed within one to three weeks, including testing, analysis, and reporting.

You will receive a detailed report that includes identified vulnerabilities, risk ratings, proof-of-concept evidence, and step-by-step remediation guidance. Reports are designed to be actionable for both technical teams and leadership.

Yes. We provide guidance to help your team address findings and can validate fixes once remediation is complete. Our goal is to ensure vulnerabilities are fully resolved, not just identified.

Yes. Our testing methodology aligns with industry standards such as the OWASP Top 10 and other widely accepted security frameworks. This ensures comprehensive coverage of the most critical web application risks.

Yes. Web application penetration testing supports compliance efforts for standards such as PCI Gap Assessments, SOC 2 Compliance, and ISO 27001 audits by validating security controls and identifying vulnerabilities that must be addressed.

We typically require application URLs, user credentials for testing, scope details, and any restrictions or sensitive areas to avoid. We work with your team to define clear rules of engagement before testing begins.
