Web Application AI and LLM
Penetration Testing
Validate the Security of the Apps that Power Your Bottomline
Zelvin Security’s independent security testing is designed to validate your security controls, so you can prove to compliance teams, procurement influencers, and enterprise buyers your data security is in alignment with their due diligence expectations.
Our testing methodologies combine the OWASP framework, complex manual testing techniques and thorough methodologies to deliver the Web Application Penetration Testing level regulated industries expect.
ACCELERATE WITH AL and LLM WITHOUT SLOWING DOWN FOR SECURITY
AI and LLM capabilities unlock innovation and introduce security risks that traditional testing simply isn’t built to detect. Modern applications now depend on dynamic models, complex APIs, and autonomous decision flows that demand a more sophisticated, human-led approach to validation.
That’s why SaaS teams, technology leaders, and FinTech innovators turn to Zelvin’s Ethical Hacking Team when they need deep, manual testing paired with clear, prioritized remediation strategies.
We understand the pressure to ship fast while satisfying enterprise security expectations. Our testers are highly skilled at navigating the balance between rapid release cycles and rigorous security assurance—so your team stays on track for every “go live” milestone.
Aligned with OWASP principles and strengthened by specialized AI/LLM testing expertise, our methodology uncovers vulnerabilities others miss, including AI access control gaps, prompt and injection paths, model-driven logic flaws, and complex data-exposure risks.
With Zelvin, you maintain velocity and deliver the secure, high-trust experience enterprise buyers expect.
INDEPENDENT VALIDATION
At Zelvin Security, our testing validates the strength of your data privacy standards, integrations, and validate the application controls protecting it. Enterprise buyers trust this independence, because we are a fully independent and follow the deep manual testing methodology expected by large mature regulated organizations.
Zelvin’s recommendations are intentionally designed to bring seamless, actionable proactive strategies for development teams to implement. Our testers bring decades of experience, deep technical expertise, and a practical understanding of modern application architectures, every finding is paired with clear, realistic guidance your software engineers can act on.
Achieve Compliance and Confidence.
We recognize the investment required to address the security risks identified during a security assessment. That's why the Ethical Hacking Team at Zelvin Security gives you an actionable strategy tailored to your technology, risks, and compliance requirements. This custom guide will save your team countless hours when it comes to remediation recommendations. Our team develops a plan to address risks at the root cause.

Web Application FAQs
-
What is a Web Application Penetration Test?
A web application penetration test is a controlled, ethical attack against your web app to find vulnerabilities an attacker could exploit. It simulates real-world threats and shows how to fix weaknesses before they are abused.
-
How long does a Web Application Penetration Test take?
Time depends on scope and complexity. Small apps can take a few days, medium-sized or API-heavy apps can take one to two weeks, and large or complex apps can take longer. We provide an estimated timeline in the proposal.
-
What exactly will you test?
We test components you authorize, typically front-end and back-end app logic, authentication and session management, APIs, third-party integrations, file uploads, business logic, input validation, and common vulnerability classes such as injection, broken access control, and cross-site scripting.
-
How do you define the test boundaries?
Boundaries are set in a written scope document. It lists domains, subdomains, API endpoints, credentials provided, excluded systems, and time windows. We will not test systems or assets not explicitly listed.
-
Do you test third-party services or cloud infrastructure?
Only if you include them in scope. For third-party platforms we typically test how your app interacts with them, not the provider’s underlying infrastructure unless you have explicit permission.
-
Do you need legal approval or a letter of authorization?
Yes. We require a signed Rules of Engagement or Authorization Letter that documents scope, timing, allowed methods, contact points, and an out-of-band emergency procedure. This protects both parties.
-
Will the test impact production availability?
We design tests to minimize impact. Some tests are intrusive and may affect availability. Those actions are agreed up front and scheduled during approved maintenance windows whenever possible.
-
How do you handle sensitive data you may encounter?
We treat all data as confidential. We follow secure handling procedures, avoid exfiltrating production-sensitive items unnecessarily, and recommend safe remediation paths. Data discovered is reported securely and deleted after the engagement according to the contract.
Web App Security testing designed to achieve compliance, remediate efficiently, prove independent security testing and build trust with enterprise clients.
SAST, DAST, & DevSecOps
-
What is the difference between SAST and DAST?
SAST (Static Application Security Testing) analyzes source code.
DAST (Dynamic Application Security Testing) evaluates and detects vulnerabilities using manual and automated testing techniques to uncover security risks.
-
Why do we need both SAST and DAST?
Each approach covers different parts of the attack surface. SAST identifies coding flaws early in development, while DAST finds runtime and configuration issues missed by code analysis. Together, they provide a more complete security picture.
-
How does DevSecOps fit into this?
DevSecOps integrates security into the software development lifecycle as new releases are deployed security is implemented prior to the release. This brings security testing (like SAST, DAST, and dependency scanning) into each build, reducing rework, improving security, and speeding up delivery.
Secure SDLC
-
How is SDLC security different from Web App Pentesting?
Traditional security testing has happened after the web application is fully built and ready to go to market.
Secure SDLC integrates testing and compliance threat modeling throughout the development process.
It is more cost and time effective to integrate security into the development process to uncover risks earlier in the dev process. This makes it easier to build an app that is ready for compliance and technical security controls necessary, today.
-
How does Ai change the security of the dev process?
Yes, now more than ever, secure code development processes are at risk for integrated risks and vulnerabilities.
AI is fast, but not secure. This rapid cycle development style is not able to detect business logic flaws and consider complex compliance needs.
Zelvin Security helps organizations safely integrate AI-powered development processes, tools and source code into the SDLC. We integrate an AI-driven analysis, carefully tune automated testing tools to reveal true risks (and less false positives), and bring expert led SDLC security consulting services to your team.
We'll eliminate noise while fine-tuning security best practices with a security-focused accountability program.
-
What is Fractional SDLC Security Consulting?
Zelvin Security provides hands-on consulting to align your SDLC with NIST SSDF, SAMM, or BSIMM.
We'll bring training and accountability to your team, decades of experience improving security early in the dev process and establish security gates to align with the compliance frameworks required by your organization.
