Security Testing is a broad term that refers to the process of checking a system, network, or piece of software for vulnerabilities that hackers and other threat actors can take advantage of. Veracode’s State of Software Security Report revealed that 83% of the study sample, comprising 85,000 software applications used by 2,300 companies worldwide, had at least one security vulnerability discovered during an initial security test. Without the test, these flaws would have been released into production, making the software vulnerable to cyber attacks.
