Application Security Testing

Enterprise application portfolios are tested regularly. Scanners run. Reports are issued. Compliance requirements are met. That does not mean access is enforced correctly or critical workflows cannot be abused.

What often goes untested is who can access what, how transactions actually work behind the scenes, and how applications and systems integrate.

Our assessments focus on those areas across web, API, mobile, and software delivery pipelines—validating the controls in-place and demonstrating exposure before it becomes a business problem.

Web Application Testing

Web applications routinely pass annual testing yet still allow access to sensitive data or critical functions.

We determine whether your most important workflows and data are truly protected, not just compliant enough to pass an audit.

API Testing

APIs decide who can access data and trigger actions behind the scenes. When they fail, exposure can scale quickly.

We determine whether those access rules actually hold, not just whether the system looks secure from the outside.

Software Delivery Security

If your release process is compromised, attackers may not need to exploit the application itself.

We examine whether your software delivery process can be manipulated to introduce unauthorized changes.

Mobile Application Testing

Mobile applications extend authentication and sensitive data onto devices outside your control.

We determine whether those controls still hold when the device cannot be trusted, not just when everything behaves as designed.

Source Code Review

External testing shows what an attacker can see from the outside. Critical security decisions, however, are made in code.

We identify structural weaknesses that may not surface through normal testing but create significant exposure.

Web Application Testing

Most web applications are tested annually. Automated scanners are run. A checklist-based assessment is performed. A report is delivered. Compliance requirements are satisfied.

That level of coverage is necessary. It is not sufficient.

Our assessments include full coverage of standard web application vulnerabilities, supported by automated tooling where appropriate.

Beyond that baseline, our testers manually evaluate the application the way a capable attacker would, asking:

Do access controls truly limit users to the data and functions they are meant to have?
Can high-value transactions such as payments, approvals, or account changes be manipulated?
Are administrative capabilities restricted to the right individuals?
Can business logic be used in ways the system designers did not intend?
Do integrations with other systems introduce exposure beyond the original trust boundary?

When source code or architectural documentation is available, we incorporate it into the assessment to increase testing coverage and confirm real-world exploitability.

Every significant finding is validated and clearly explained, with impact defined in business terms.

Mobile Application Testing

Mobile applications place sensitive functionality and data on devices the organization may not fully control. The applications handle authentication, payments, and personal information while relying on backend systems that often assume the client behaves as intended.

If controls are weak at the mobile layer, exposure can extend well beyond a single device. Mobile applications can be reverse engineered, modified, or automated at scale, creating risk that is difficult to detect from the server side.

Our mobile testing evaluates both the application itself and its interaction with backend services, focusing on questions such as:

Do authentication and session controls remain secure when the device itself is compromised?
Is sensitive data exposed through local storage, backups, or device-level access?
Can high-value actions be initiated or manipulated from a modified device?
Does the backend rely on assumptions about the integrity of the mobile client?
Are communications between the application and backend properly protected and validated?

We test both Android and iOS applications. Effective iOS assessment in particular requires tooling, device preparation, and operational capability that many firms no longer maintain.

Where source code or architectural documentation is available, we use it to deepen analysis and confirm how controls are implemented in practice.

We document demonstrable exposure, explain the real-world impact, and provide clear guidance for remediation.

API Testing

APIs often sit at the center of modern applications. They control how data is accessed, how transactions are processed, and how systems communicate with one another.

When weaknesses exist at this layer, the impact can extend beyond a single user or screen. Exposure can affect large volumes of data or core business functions.

Our API testing is performed directly against the service layer, not solely through the user interface of the application.

We assess:

Do access controls consistently restrict users to the data and functions they are authorized to use?
Are customer or tenant boundaries properly enforced?
Are authentication and token controls implemented correctly?
Can core business rules be bypassed through direct interaction with the API?
Do integrations create unintended access between different systems?

When API documentation or source code is available, we incorporate it directly into the assessment to uncover undocumented endpoints, internal logic paths, and exposure that surface-level testing does not reveal.

Every material finding is substantiated, reproducible, and prioritized based on real-world risk.

Source Code Review

Application testing is strongest when the implementation can be examined directly. While dynamic testing reveals how a system behaves externally, source code review provides visibility into how critical controls are actually implemented.

Our code review is manual and threat-driven, focusing on issues that require judgment and contextual understanding, including:

Inconsistent enforcement of access controls across different parts of the application
Business logic flaws that allow sensitive actions to be performed outside intended workflows
Privilege escalation paths created by edge cases or error handling conditions
Implicit trust relationships between components that are not visible through external testing
Custom security mechanisms that appear sound but fail under realistic use

This approach differs from firms that rely heavily on automated static analysis tools which generate large volumes of unverified findings. We use tooling selectively, but conclusions are drawn through direct analysis of the codebase.

Source code review is often integrated into web, API, or mobile assessments to increase depth and validate exploitability. It can also be performed as a standalone engagement for high-impact systems.

Our objective is not to enumerate stylistic issues, but to identify conditions that create real exposure and provide clear, prioritized remediation guidance.

Software Delivery Security

Modern applications depend on automated systems to build, test, approve, and release code into production. These systems govern who can modify software, how changes are validated, and how releases reach customers.

If controls at this layer are weak, an attacker may not need to exploit the application at all. Compromise of the CI/CD pipeline can allow unauthorized code, backdoors, or redirects to be introduced into production through legitimate release mechanisms.

Our assessments evaluate the integrity of the software delivery process, including:

Who has the ability to modify source code and release definitions?
How is developer access controlled and monitored?
Can automated workflows be altered to execute unintended behavior?
How are build systems secured and isolated from unauthorized influence?
Are sensitive credentials stored and used securely during the build and release process?
Can software artifacts be modified between build and production deployment?

Where weaknesses are identified, we validate impact by demonstrating how those conditions could be used to gain unauthorized access, extract sensitive information, or introduce unauthorized changes into the release process.

Our focus is on systemic risk within the delivery pipeline, not isolated configuration gaps.
