The OWASP Top 10 Explained: A 2025 Security Checklist for Your Web App

"

Meerako — Dallas, TX experts in building secure, compliant, and enterprise-grade software.

Introduction

A single security breach can destroy a startup. It can lead to millions in fines (especially with HIPAA or FinTech), a complete loss of customer trust, and the end of your business. In 2025, web application security is not an "add-on" or a "nice-to-have." It is the non-negotiable foundation of your entire product.

The industry-standard guide for this is the OWASP Top 10, a list of the most critical web application security risks.

At Meerako, security is not an afterthought; it's built into our development process from day one. We build 5.0★ rated applications because they are secure by default. This guide will break down the OWASP Top 10 in simple terms and explain how we defend against them.

What You'll Learn

-   What the OWASP Top 10 is and why it matters. -   A simple explanation of critical risks like Broken Access Control and Insecure Design. -   Actionable development practices to defend against these threats. -   How Meerako's "Security-First" process protects your application.

The OWASP Top 10 (2025 Highlights)

1. A01: Broken Access Control

2. A02: Cryptographic Failures

3. A03: Injection

-   What it is: The classic. This is when an attacker "injects" malicious code into a query. The most famous is SQL Injection, where an attacker can dump your entire database from a simple login form. -   How Meerako Prevents It: We never build queries by concatenating strings. We use modern Object-Relational Mappers (ORMs) like Prisma or TypeORM, which use parameterized queries. This automatically sanitizes all user input, making SQL injection impossible.

4. A04: Insecure Design

-   What it is: A new category. This isn't a bug, but a flaw in the business logic. (e.g., Designing a "ticket transfer" feature without limiting how many times a ticket can be transferred, allowing for fraud). -   How Meerako Prevents It: This is why our Discovery Workshop is critical. Our Dallas-based architects and product managers (with 500+ domain experts) "threat model" your application before we write code. We ask "How can this be abused?" and design guardrails from the start.

5. A05: Security Misconfiguration

-   What it is: The "oops" category. This is leaving default passwords on, enabling "debug" mode in production, or leaving an AWS S3 bucket public. -   How Meerako Prevents It: Our DevOps process is built on Infrastructure as Code (IaC). Our AWS environments are defined in code and peer-reviewed. We have automated CI/CD pipelines and security scanners (like Snyk) that check for misconfigurations before they are deployed.

The Rest of the List (Simplified)

Conclusion

Security is a process, not a product. It's a culture of vigilance. You don't get a 5.0★ rating like Meerako by cutting corners on security.

We build secure, compliant (HIPAA, FinTech, etc.), and reliable applications because it's the only way we know how to build. We protect your business by protecting your data, giving you the confidence to scale.
