The ISTQB® Certified Tester Security Test Engineer (CT-STE) certification focuses on how security testing should be done, presenting security methodologies, standards, techniques, processes, and tools.
As cyberattacks grow in frequency and sophistication, a robust engineering-focused approach to testing security is more critical than ever. Without security testing aligned to an IT system’s specific risk levels, vulnerabilities may be exploited, potentially during production, with devastating consequences. The CT-STE certification aims to bridge this gap, ensuring professionals can proactively create maximum transparency about effective security risk exposure to secure systems against emerging threats.
“I took my certifications through ASTQB & AT*SQA because they were the only ones that could put you on the Official U.S. List of Certified & Credentialed Testers™ as well as the ISTQB Successful Candidate Register. I love that fact and it is the #1 reason that I chose them as my preferred exam provider of all time.”
