Toronto is one of North America’s fastest-growing digital economies, with thousands of organizations relying on secure applications for finance, healthcare, retail, and government services. But with cyberattacks rising, businesses cannot afford to release software without ensuring it’s secure.
Source Code Review in Toronto has become a critical safeguard—helping companies identify vulnerabilities hidden in their applications before attackers exploit them.
What is Source Code Review?
Definition:
Source code review is the process of analyzing the internal code of an application to detect vulnerabilities, performance bottlenecks, and compliance issues.
Why is it Important?:
-
Detects flaws early in the software lifecycle
-
Protects customer and business data
-
Ensures applications comply with regulatory requirements
-
Reduces costs of fixing vulnerabilities post-deployment
