Web application penetration testing services we provide

Innowise conducts targeted security assessments to validate protection mechanisms, access controls, and business logic across your web systems.

  • External testing
  • Authenticated testing
  • Backend testing
  • Logic validation
  • Retesting

External web application testing

We assess the security posture of publicly exposed application components, including open endpoints, input fields, and client-side logic. Using this, we gauge third-party threats and the likelihood of gaining access to your apps.

Authenticated and role-based testing

We examine session management & handling of JWT tokens, the enforcement of role separation, and access control mechanisms within authenticated application zones, uncovering potential paths for horizontal & vertical privilege escalation.

API and backend logic testing

We examine your backend architecture and various REST, GraphQL, or SOAP APIs to reveal underlying structural vulnerabilities that impact the integrity of data and the effectiveness of authorization mechanisms.

Platform engineers configure API gateways to orchestrate secure communication across service networks.

Business logic and workflow validation

We identify hidden security-related problems that can be found in complex application workflows, such as payment gateways and multi-step shopping carts, that standard automated surface checks often miss.

Web application retesting verification

Once your development team releases patches, our targeted retesting verifies that previously identified weaknesses have been remediated and subsequent fixes don’t create new exposure points.

What you’ll get from web penetration testing services

Application-layer weakness visibilityThis assessment offers a high degree of visibility into security gaps of web applications in relation to data protection and overall service availability. You receive a precise map of structural vulnerabilities to make judicious technical decisions.
Validated access and auth boundariesThe testing process ensures that your authentication mechanisms and role-based access controls function exactly as intended. Business owners also gain assurance that sensitive user data is isolated from all other users across the entire application/site.
Reduced application-layer risk exposureThis engagement delivers substantial risk reduction by prioritizing and identifying the high-impact vulnerabilities. You’ll gain a better understanding of how to mitigate risk to your most valuable corporate assets and maintain the overall integrity of your systems.
Prioritized remediation and patchingStructured findings direct your IT department’s attention to glaring security issues. Teams use a clear hierarchy of vulnerabilities, which allows them to assign resources appropriately and apply patches where they matter most.
Enhanced internal security managementSecurity evaluations enhance your internal risk management programs by providing practical, highly detailed technical insights. Which is used to develop long-term plans for security and continually improve infrastructure.
Uncover hidden risks with pentest web services

Why choose Innowise as your web penetration testing company

As a leading web application penetration testing company with 85% of middle and senior-level security engineers and 93% of clients returning for follow-on engagements, we bring the depth and continuity that enterprise penetration testing programs require.

Web penetration testing services lifecycle

Innowise’s website penetration testing services center around a transparent methodology that includes a well-defined scope, clear communication, and reliable delivery.

Scope definition & application review

Our engineers define testing boundaries and gather all the necessary info around your application architecture.

Threat modeling & test planning

We build a targeted test plan based on your app's architecture, data flows, and business logic to identify the attack surfaces and risk vectors.

Controlled penetration testing execution

By performing manual and automated security tests within an agreed scope, we simulate the same attack scenarios you would experience in a real-world environment.

Vulnerability validation & risk assessment

All of our findings are manually validated so that we can eliminate false positives and accurately determine the business impact of each vulnerability found.

Reporting & remediation guidance

Every report we deliver contains an organized and prioritized list of findings and developer-ready remediation guidance to make the required corrective actions.

Retesting & security posture verification

After applying patches, we re-test the areas that are affected by the vulnerability to confirm that the weaknesses have been closed.

    While automated scanners can identify surface-level syntax issues, the threats that can put a company at risk are found much deeper: within the logic governing transactions, access decisions, and data flows. This deeper level requires engineers with an understanding of how the application was meant to behave and an ability to identify where the actual system implementation does not match the design.

    FAQ

    Yes, we analyze these critical vulnerabilities. This means we identify injections, cross-site scripting, and other structural flaws of web applications to help lock down access to sensitive data.

    No, automated scans cover the surface level only, and qualified security engineers will verify complex business logic, trace multi-step attacks, and validate any findings that cannot be reliably found by an automated tool.

    We prioritize testing your components based on their core business value. For example, high-risk areas, including payment processing, private data, and mission-critical logic, get manual review almost immediately.

    The scope encompasses your frontend interfaces, backend APIs, authorization mechanisms, and internal application logic. Together with your team, we thoroughly outline the full extent of your test during the initial project planning session.

    Our team provides a prioritized report outlining recommended actions to remediate the issues found during each engagement. Development teams use this as a systematic remediation plan.

    There are no established timelines for web application penetration testing engagements, because each application has its own unique features and level of complexity. However, straightforward engagements normally take about 1-2 weeks, and larger applications or those that contain multiple components may require 3-4 weeks (including the time taken for the report).

    Our goal is to minimize operational disruption on production systems during any assessment. Any system testing will be performed either in a staging environment or within your maintenance schedule, based on your prior approval.

    Yes, every penetration test we conduct will always include a comprehensive re-test. During this process, we will validate your patch repairs to ensure they are working correctly and also ensure no new issues have been introduced by applying them.
