Functional, regression, integration, and load testing for software systems before they reach production.
Software audit, code review, dependency analysis, and verification against technical and security standards.
Web application audit, performance assessment, accessibility compliance, and front-to-back verification.
Security assessments, vulnerability identification, defensive review, and structured remediation guidance.
Nexyla is the technical brand of KSV Análises Técnicas Industriais Ltda — a desk dedicated to testing, verification, web auditing, and digital security services for software teams, web operations, and businesses with technical infrastructure to defend.
Our work is structured. We test what teams ship before users do. We verify code against the standards it's supposed to meet. We audit web applications for the things teams stopped looking at six releases ago. And we work the security perimeter with the discipline that defensive technical work actually requires.
What we don't do: vague advisory, generic consulting, marketing-flavored "digital transformation". What we do is technical work — measured, documented, and delivered as a structured report you can act on. The output is the audit, the test result, the security finding, and the path to remediation.
We operate from Rio das Ostras, Rio de Janeiro — close enough to the coastal industrial corridor of RJ, connected to clients across Brazil, with the technical depth to take on the kind of files that don't fit the usual consultancy template.
Functional, regression, integration, smoke, and load testing for software systems before they ship. Manual and structured automated coverage.
Source code review, static analysis, dependency audit, and verification against technical, quality, and security standards your team operates under.
Full-stack web application audit — functional, performance, SEO basics, accessibility compliance, and the technical hygiene of what's actually live in production.
Defensive security assessment, vulnerability identification, configuration review, and structured remediation guidance — performed within an agreed scope and authorization.
Verification of digital services against contracted specs — APIs, integrations, third-party services, and the technical performance of vendor relationships.
Structured technical reports — findings, severity classification, reproduction steps, recommended actions, and the kind of documentation that leadership and engineering both read.
What's being tested, what's in scope, what's out of scope. Authorization, environment, and the rules of engagement defined before any work begins.
Structured testing, audit, and verification work — performed against the agreed scope using the methodology appropriate for the technical surface.
Findings classified by severity, with reproduction steps, technical evidence, and the context engineering teams need to actually act on them.
Structured technical report — executive summary, detailed findings, recommended remediation, and direct support during the remediation cycle.
Testing and security work means nothing without a frame. We operate against the established frameworks that define what good practice looks like in modern software and digital security.
Open Worldwide Application Security Project — the reference framework for web and application security assessment, including OWASP Top 10 and ASVS.
Reference standards including ISO/IEC 27001 (information security management) and ISO/IEC 25010 (software quality model) inform our methodology.
Engagements operate in line with the Brazilian General Data Protection Law (Lei nº 13.709/2018), particularly when handling client data during testing.
All security testing is performed only within explicitly authorized scope, in line with Brazilian law (Marco Civil da Internet, Lei nº 12.965/2014) and ethical standards.
Tell us what's being tested, what the engagement looks like, and what you need at the end. We'll respond within one business day with a structured proposal.
