Cyberattacks grow every year. According to IBM’s <\/span>Cost of a Data Breach<\/span><\/a> 2024 report, the average cost of a data breach reached $4.88 million globally. This scenario requires companies to rethink how they develop software. Security can no longer be treated as an additional layer applied at the end of the process, it needs to be present from the first line of code.<\/span><\/p>\n

Secure coding is the practice of developing software with resistance to vulnerabilities from the beginning of the development cycle. Instead of only thinking about functionalities, each architecture and implementation decision considers possible security breaches. At NextAge, we’ve applied these best practices for 18 years in all projects we develop for our clients, and we’ve gathered some of what can be applied in this article.\u00a0<\/span><\/p>\n

What is secure coding?<\/b><\/h2>\n

Secure coding means writing code that prevents known vulnerabilities through specific techniques, standards, and tools applied throughout development. While traditional development focuses first on making the system work and then worrying about security, secure coding integrates protection from conception.<\/span><\/p>\n

This care extends throughout the entire software development life cycle (SDLC<\/a>). From planning, where security requirements are identified, to maintenance, when updates fix vulnerabilities discovered after release.<\/span><\/p>\n

Why is secure coding essential for your business?<\/b><\/h2>\n

Security in code protects the most valuable asset of modern companies: data. With LGPD (General Data Protection Law) in effect in Brazil and similar regulations in other countries, security failures can result in fines reaching up to 2% of the company’s annual revenue. Beyond legal penalties, there’s the operational cost.<\/span><\/p>\n

The <\/span>Ponemon Institute<\/span><\/a> demonstrated in its 2023 study that fixing a vulnerability during production costs 30 times more than fixing it during development. This difference occurs because problems detected late require rework across multiple system layers, extensive testing, and coordination of emergency deployments.<\/span><\/p>\n

Business continuity also depends directly on software security. Ransomware that paralyzes systems can cost millions in lost revenue, not to mention the impact on the supply chain and customers. At NextAge, we develop systems that keep operations protected through consistent security practices, applied in our modern Staff Augmentation services, Software Management Services, or Adaptive scope projets.<\/span><\/p>\n
