Why code security review is needed?

Programmers often follow incorrect programming practices which leads to security loopholes. To mitigate the risks, it is important to perform code review to capture security loopholes, before the code it deployed on to live production systems. Code review and code analysis enables your developers to review, find, and eliminate vulnerabilities before an application goes live and helps software purchasers identify flaws in applications before they buy.

Many organizations use tools but it had been observed that this method has its own obvious limitations. Because of this, the inaccurate results can waste your developers' time in hunting down false positives, thus slowing development timelines to the point where competitiveness suffers. But with the security of your enterprise on the line, you need some way to review code quickly and cost-efficiently. That's where Valency Networks can help.
