Uncover Application Security Risks Before Attackers Do
Applications remain one of the most targeted attack surfaces across legacy and modern environments. Business applications, customer portals, SaaS platforms, APIs, cloud-hosted systems, AI-enabled features, and third-party integrations can all introduce risk when security controls are incomplete, outdated, misconfigured, or not fully validated.
Legacy applications often carry technical debt, outdated components, weak session handling, older authentication patterns, and years of accumulated functionality. Modern applications can introduce complex authorization models, API exposure, cloud integrations, AI-driven workflows, and business logic flaws.
Zelvin Security provides application penetration testing from an ethical hacker’s perspective to uncover real-world attack paths, validate meaningful risk, and deliver clear remediation guidance. The goal is simple: help your organization understand what matters most and address application security risks before they become business problems.
Application Penetration Testing Helps Organizations
Zelvin Security provides independent third-party Web Application Penetration Testing designed to uncover vulnerabilities, validate real-world risk, and identify issues that could impact applications, users, customers, and sensitive data.- Uncover application vulnerabilities before attackers discover them.
- Validate security controls through real-world testing.
- Improve visibility into practical attack paths and exploitable weaknesses.
- Reduce business and operational risk tied to application security gaps.
- Strengthen secure development practices with clear remediation guidance.
- Support customer security reviews, vendor assessments, governance, and procurement initiatives.
- Demonstrate independent security validation to customers, stakeholders, and business partners.
- Receive risk-based documentation that includes clear findings, remediation strategy, and prioritized next steps.
- Obtain a Letter of Attestation upon request to support customer, vendor, and procurement security reviews.

Web Application Penetration Testing
Web Application Penetration Testing is a hands-on security assessment performed from the perspective of a real-world attacker. The objective is to identify vulnerabilities, validate whether they can be exploited, and determine the potential impact on application users, sensitive data, business workflows, or supporting systems.
Unlike automated scans that primarily identify known issues, Zelvin Security ethical hackers evaluate application behavior, security controls, and business logic to understand how attackers may attempt to gain unauthorized access, manipulate functionality, expose sensitive information, or compromise accounts.
Testing may be performed from unauthenticated, authenticated, and role-specific perspectives based on the application scope. This allows Zelvin Security to evaluate external attack paths, authenticated user risk, and whether different roles, permissions, workflows, or application functions introduce additional exposure.
Zelvin Security methodology combines structured testing, advanced tooling, hands-on testing and validation, human led AI assisted techniques where appropriate, and industry-recognized application security guidance, including OWASP Top 10, OWASP Web Security Testing Guide, and OWASP Application Security Verification Standard principles when applicable. Testing focuses on identifying meaningful risks that could affect the confidentiality, integrity, or availability of application data and functionality.
AI and LLM Security Testing for Applications
Organizations are rapidly integrating AI-enabled functionality into customer-facing and internal applications through chatbots, AI assistants, large language models, embedded workflows, automation, and third-party AI integrations. These features expand capability but also introduce risks that traditional application security testing was not designed to catch.
Zelvin Security's goal is not to slow innovation but to help organizations understand where security needs to be applied so they can build and deploy with confidence. Whether a team is experimenting with AI features or moving them into production, we focus on identifying practical risks, providing clear guidance on how to address it, not on whether something should be built.
Zelvin Security evaluates AI and LLM functionality as part of a Web Application Penetration Test when AI features are embedded within the application environment, or as a standalone engagement when the AI system, chatbot, assistant, workflow, or integration is the primary focus.
Testing typically includes:
-
Prompt injection and instruction manipulation
- Sensitive data exposure through AI responses
- Authorization and access control gaps
- Model-driven business logic flaws
- Excessive access to tools, APIs, or data
- Insecure AI integrations and third-party service exposure
- Unsafe handling of user-supplied input
- AI workflow abuse paths
Zelvin Security testing is aligned with recognized application and AI security principles, including OWASP guidance, with the objective of identifying practical AI-related risks that traditional web application testing may not fully surface.
Expert Assurance & Attestation
Documentation is designed to support:
- Procurement requirements
- Customer security reviews
- Vendor security assessments
- Cybersecurity assurance initiatives
- Internal risk management efforts
- Stakeholder and client assurance efforts
Strategic Documentation. Actionable Results.
A penetration test should do more than reveal application security issues. It should help teams understand what matters, what to fix first, and how to move forward with confidence.
A common concern after any penetration test is being handed a long list of vulnerabilities with no clear sense of where to begin. Zelvin Security reporting is designed to solve for that problem. Findings are organized by risk-based priority, tied to root cause, and paired with practical remediation guidance so teams understand what to focus on first and why.
Reporting is built for both technical teams and business decision-makers and may include:
- Executive summary with visual risk overview and vulnerability breakdown by type
- Ethical Hacker's Perspective offering insight into how findings were identified and what they mean in a real-world attack context
- Root cause analysis designed to drive action, not just awareness
- Risk-based prioritization to help teams focus on what matters most
- Practical remediation guidance tailored to the application environment
- Supporting evidence and strategic recommendations
Our goal is to help organizations move from findings to informed action with clarity and confidence.
