Testing
Using production data in test environments is one of the most common compliance violations in software engineering — and one of the easiest to prevent. Test data masking and anonymization are the tools that let your QA team work with realistic data while keeping regulators and auditors satisfied. This guide explains

Webhook endpoints are unauthenticated HTTP endpoints that receive data from external services. They're a common target for attacks — and most security issues stem from missing a few basic checks. This checklist covers 12 security tests every webhook implementation should pass. 1. Signature Verification Is Enforced Risk: Anyone who
Security
IoT devices are deployed everywhere — homes, factories, hospitals, infrastructure — and they're notoriously insecure. Default passwords, unencrypted communications, and insecure OTA updates have led to massive botnets and data breaches. Security testing for IoT requires different techniques than web application testing. This guide covers the fundamentals of IoT security
Testing
Webhook signature verification is the one security control standing between your server and arbitrary POST requests. If you're not testing it, you're trusting that your implementation is correct — which is how security bugs get shipped. This guide covers how to test HMAC and JWT signature verification
Testing
Security vulnerabilities have a compounding cost curve that makes testing late particularly painful. A SQL injection found in a code review takes an hour to fix. The same vulnerability found after a breach means forensic investigation, regulatory notifications, customer remediation, legal exposure, and reputational damage that no SLA covers. Shift-left
Testing
Audit logs are one of the most frequently under-tested components in production systems. Teams write careful tests for business logic, API endpoints, and database queries — but the logging subsystem that records who did what and when often goes untested until a compliance audit or security incident reveals that it doesn&

SOC 2 is a certification that enterprise customers increasingly require before signing a contract. For SaaS companies, a SOC 2 Type II report is often the difference between winning and losing six-figure deals. Yet most engineering teams treat SOC 2 preparation as a documentation exercise managed by compliance consultants — and

PCI DSS (Payment Card Industry Data Security Standard) governs any organization that stores, processes, or transmits cardholder data. Version 4.0, released in 2022 and mandated from March 2025, introduced significant changes to how testing requirements are structured — moving from point-in-time assessments toward continuous monitoring and testing. The core insight

Building healthcare software means operating under HIPAA's Technical Safeguards — a set of required and addressable implementation specifications that directly govern how your application must behave. Unlike other compliance frameworks that are largely process-oriented, HIPAA's Technical Safeguards translate almost entirely into testable application behaviors. A HIPAA violation

GDPR has been in force since May 2018, yet data protection authorities across Europe continue to hand out record fines. In 2023 alone, Meta received a €1.2 billion penalty. The gap between "we think we're compliant" and "we can prove we're compliant&
Supabase
Row Level Security is one of Supabase's most powerful features — and one of the most dangerous to get wrong. A misconfigured RLS policy can silently expose every row in a table to every authenticated user, or lock out legitimate access entirely. Neither failure is obvious until something goes

TLS misconfiguration is one of the most common and consequential security issues in web applications. Weak cipher suites, expired certificates, deprecated protocol versions, and missing HSTS — these issues are easy to find with the right tools and easy to automate in CI. This guide covers the full TLS/SSL testing
