Protect your users, data, and brand with practical security engineering.
Security cannot be bolted on as an afterthought. We conduct deep technical reviews to uncover misconfigured servers, exposed environment variables, insecure authentication flows, and dependency vulnerabilities.
Modern web applications face automated scrapers, brute-force attacks, SQL injection attempts, leaky S3 buckets, exposed API tokens in client bundles, and unpatched server software. A single security breach can devastate user trust and lead to regulatory penalties.
Who this Security & Infrastructure Audits practice is engineered for
Built for technical leaders, founders, and product teams requiring senior execution rather than amateur experimentation.
What is included in this service
Every Security & Infrastructure Audits engagement delivers production-grade architecture, verified testing, and comprehensive code handover.
Full-Stack Code & Secret Leakage Audit
Static code analysis to detect exposed API keys, unsafe eval execution, SQL injection vectors, and Cross-Site Scripting (XSS).
Authentication & Session Security Review
Auditing JWT token lifecycles, CSRF protections, OAuth callback validation, password hashing algorithms, and rate limiting.
Server & Cloud Configuration Hardening
Securing SSH access, closing unnecessary server ports, configuring UFW/fail2ban, and setting up strict IAM permission boundaries.
Security Headers & CSP Implementation
Deploying Content Security Policy (CSP), Strict-Transport-Security (HSTS), X-Content-Type-Options, and CORS configurations.
Database Access & Storage Bucket Audits
Verifying Row-Level Security (RLS) policies in PostgreSQL/Supabase, public bucket access restrictions, and encryption at rest.
Remediation Guidance & Re-Testing
Delivering a prioritized vulnerability report with actionable code snippets and verifying all resolved issues.
Tangible Production Asset Manifest100% Handover
Direct codebase artifacts transferred to your private organization
Modern technologies and frameworks we leverage
Battle-tested, enterprise-grade tooling with strict type safety and deep ecosystem reliability.
How we engineer and ship this service step-by-step
Our battle-tested 4-phase framework ensures zero downtime, complete visibility, and production-grade delivery for Security & Infrastructure Audits.
Scope Definition & Non-Destructive Scanning
We define testing boundaries and run static analysis, dependency scanning, and header inspections.
Manual Code & Architecture Inspection
Our senior engineers examine authentication flows, database queries, access control policies, and cloud IAM roles.
Vulnerability Report & Action Plan
We compile findings into a clear report ranking risks by business impact with direct engineering fixes.
Patch Implementation & Verification
We assist your team in applying recommended security patches and re-test to confirm all vectors are closed.
Feedback on our Security & Infrastructure Audits practice
Direct reviews and authentic quotes from CTOs, technical founders, and executives who engaged this practice.
“JoinAffix's infrastructure review identified an unencrypted internal Redis port and outdated SSL cipher suites before our external compliance review. Thorough, professional, and fast.”
“Prior to our Series A fundraising, JoinAffix conducted a rigorous security audit of our healthcare SaaS. They discovered and resolved cross-tenant data leakage vectors in our GraphQL resolvers that had slipped past our internal QA. Outstanding attention to detail.”
“JoinAffix's security audit uncovered critical CORS misconfigurations and an exposed database endpoint that our previous dev shop missed. Their remediation plan was clear, prioritized, and easy to execute.”
“Their server hardening checklist and Content Security Policy implementation protected our public API from an aggressive scraping attack that hit us just three weeks later.”
“Their SOC2 Type II compliance audit and penetration testing caught a zero-day dependency vulnerability in our Python microservice days before audit certification.”
“JoinAffix's infrastructure review identified an unencrypted internal Redis port and outdated SSL cipher suites before our external compliance review. Thorough, professional, and fast.”

Ask an Engineer DirectlyThis is a practical technical engineering and vulnerability audit designed to harden code, infrastructure, and access controls. While it establishes the technical foundations needed for SOC 2 or ISO 27001 compliance, formal compliance certification requires an accredited auditing firm.
