Smarter web application security penetration testing with Penti
Penti’s web app penetration testing tool works smarter, combining AI-led efficiency with expert-led penetration testing to simulate internal and external attacks on web applications and identify security weaknesses across your systems. These AI-driven tests identify real-world attacks that could succeed at gaining access to your systems and provide remediation guidance that can prevent breaches from occurring in the first place.
By helping identify vulnerabilities in web application infrastructure elements like DNS servers and firewalls, Penti pinpoints where attackers can gain access to sensitive data if exposures are left unresolved. Regular web application pentesting and vulnerability scanning are key aspects of a security strategy that support your company’s software development lifecycle.
Protect, comply and grow with our web application penetration testing
Web applications are commonly the top target of brute force attacks and login credentials stuffing — typical strategies that seek to exploit system vulnerabilities and misconfigurations, often resulting in devastating breaches, especially for SMBs. Consistent web app penetration test execution and penetration testing practices ensure that your company doesn’t fall prey to sophisticated attacks and help protect sensitive data.

How we pentest web applications
More than a web app penetration test provider, Penti delivers comprehensive web application penetration testing and network penetration testing powered by AI and expert validation informed by our certified pentesters’ expertise for your actionable security insights.
Sample Web Application Penetration Testing Report
Every web application and API engagement ends with a report your dev team can act on the same day. Penti documents every vulnerability found, the exploitation steps used to confirm it, and a prioritized fix list organized by urgency — with compliance evidence attached for your auditors.
Executive Summary
Opens with report composition context — a compilation of findings from actual Penti engagements with web application and API scopes, covering OWASP Top 10, advanced injection attacks, authentication and authorization bypass, and business logic vulnerabilities. A Key Findings Summary states total Critical, High, Medium counts and the number of security controls validated. The Most Significant Findings section lists the top vulnerabilities with one-sentence impact descriptions. Followed by an Impact Assessment and a Recommendations Priority timeline.
Scope & Our Tools
Scope section lists all categories of web assets tested: external-facing applications, authenticated portals and admin panels, CRM and financial platforms, and APIs — with the full technology stack covered (frontend frameworks, backend languages, databases, cloud providers). Our Tools section lists every testing instrument organized by attack category: proxy and interception, fuzzing and discovery, injection testing, authentication and authorization, API testing, and specialized tools.
Manual Assessment Results
A summary table listing every confirmed finding with title, status (Active or Remediated), and risk level. Followed by a detailed card for each finding — description of the vulnerability, what was done during testing to confirm it, risk level, OWASP category, compliance impact (PCI DSS / NIST control violated), and step-by-step remediation guidance with code examples.
Prioritized Remediation
A three-tier action plan: Tier 1 (24–48 hours) addresses the most critical findings requiring immediate action; Tier 2 (1–2 weeks) covers High-priority findings with clear fix paths; Tier 3 (1–3 months) addresses architectural improvements and process-level security controls. Each item includes the business impact if unpatched, technical effort estimate, and specific recommended actions.
Re-testing
Retest schedule and confirmed results. The section shows which findings have already been retested and verified as remediated — with original risk level, retest date, and new status — and which remain pending. Retest timeline: Tier 1 within 1 week, Tier 2 within 2 weeks.

FAQ
How are web application penetration tests performed?
Penti’s penetration testing simulates real-world attacks on your application to identify vulnerabilities and exploit them safely before attackers can. Our security experts combine AI-powered reconnaissance with supervised agentic-AI testing techniques to assess authentication, access controls, input validation, session handling, and business logic. Each test is tailored to your web app’s architecture and threat model.
What is the difference between web application testing and vulnerability scanning?
Vulnerability scanning is automated and identifies known issues based on signatures or rules. While useful, it can often produce false positives and miss logic flaws. Web application testing involves human experts actively probing your web app to uncover complex vulnerabilities and assess their exploitability and business impact.
Is automated penetration testing better for web apps than manual testing?
No. While automation helps with breadth and speed, manual testing provides depth. Only manual testers can discover nuanced vulnerabilities like broken access controls, IDORs, or chained exploits. Penti combines AI-driven pentesting with manual tests to deliver high-coverage, high-accuracy results.
What is OWASP Top 10?
The OWASP Top 10 is an industry-standard list of the most critical web application security risks, including injection attacks, broken authentication, and insecure design. Penti’s testing methodology aligns with this framework and goes beyond it to cover emerging threats.
How does Penti prioritize web application vulnerabilities?
Each finding is automatically analyzed and scored using real-world exploitability, business context, and potential impact. This ensures your team can confidently triage and remediate the most pressing risks first.
