Test the attack surface before it becomes an incident.
ShabuShabu Security provides authorized penetration testing and vulnerability assessment services for web applications, APIs, SaaS platforms, authentication systems and AI-powered products.
Security testing should answer more than “what vulnerabilities exist?”
A useful penetration test should explain how a system can be attacked, which security boundary fails and what an attacker could realistically achieve.
ShabuShabu Security combines structured reconnaissance, manual penetration testing and controlled exploit validation to identify weaknesses that matter in the context of the actual product.
Understand the system
We map roles, interfaces, trust relationships and security-sensitive workflows before attempting exploitation.
Test like an attacker
We examine how legitimate product behavior can be combined with technical weaknesses to create an attack path.
Report for engineers
Findings include technical context, impact, reproduction information and practical remediation priorities.
Security testing for the systems your users and infrastructure depend on.
Choose a testing area based on the part of your product that needs the deepest offensive-security review.
Web Application Penetration Testing
Test authentication, session handling, authorization, input processing, business logic and other security boundaries within modern web applications.
Explore web application testing →API Security Testing
Assess authorization models, object access, data exposure, authentication mechanisms and abuse of application interfaces.
Explore API security testing →AI & LLM Security Testing
Review AI applications for prompt injection, unsafe tool access, data leakage, agent abuse and permission failures.
Explore AI security testing →Security Crash Test
Run a broader controlled attack simulation before launch, a major release or a high-risk product change.
Order a Security Crash Test →Authentication & Authorization Testing
Look for account takeover, role bypasses, privilege escalation and cross-user or cross-tenant access failures.
Explore application testing →Business Logic Security Testing
Test whether legitimate application workflows can be manipulated to achieve unintended actions, access or financial outcomes.
View our methodology →One product can contain many security boundaries.
The assessment is shaped around the architecture and behavior of the product rather than a generic vulnerability checklist.
Authentication
Login flows, password reset, MFA, session handling and account recovery.
Authorization
User roles, privilege boundaries, cross-account access and administrative controls.
Input & Data Handling
User-controlled input, file handling, data processing and potentially dangerous interpretation.
API Access
Endpoint authorization, object access, request manipulation and sensitive response data.
Business Logic
Workflow assumptions, limits, sequence abuse and unintended combinations of legitimate actions.
AI Workflows
Prompt handling, model-connected tools, data access and agent permission boundaries.
Integrations
External services, webhooks, application connections and trust between connected systems.
Sensitive Functions
Account administration, payments, user data, exports and other high-impact product actions.
Examples of security questions we investigate.
The exact tests depend on the architecture and authorized scope, but these examples illustrate the type of attack reasoning used during an assessment.
Application & Access Security
API & Modern Product Security
Automation supports the test. Human reasoning drives it.
Automated tooling can identify known signatures, configuration issues and useful reconnaissance data. It cannot fully understand what a product is supposed to do or how legitimate functionality can be abused.
That is why manual analysis remains central to ShabuShabu security testing, especially for authorization, business logic, attack chains and AI-connected workflows.
A security assessment should create a clear path to remediation.
Findings are structured so that engineering and security teams can understand the issue, reproduce it and decide what to address first.
Executive Summary
A high-level overview of the assessment, main security risks and the most important remediation priorities.
Technical Findings
Detailed descriptions of identified vulnerabilities, affected functionality and technical context.
Impact Analysis
An explanation of what an attacker could realistically achieve if the vulnerability were exploited.
Evidence
Relevant proof, request examples and reproduction information needed to understand important findings.
Remediation Guidance
Practical recommendations for reducing or removing the underlying security weakness.
Retest
Optional verification after fixes are applied to confirm that identified attack paths are no longer reproducible.
Security testing is most valuable before risk becomes expensive.
Before product launch
Review exposed functionality and critical security boundaries before users and attackers reach the product.
Before a major release
Test new workflows, permissions and integrations that materially change the attack surface.
After architecture changes
Reassess security after authentication, API, infrastructure or application architecture changes.
Periodic security review
Revisit mature products as features, integrations and user behavior expand over time.
Find the attack paths before they reach production.
Tell us what you need tested, which systems are in scope and whether you are preparing a launch, release or broader security review. We will structure the assessment around your actual product attack surface.
