  • Penetration Testing: Performing controlled attacks on web applications. APIs, infrastructure, and simulate real-world hacking attempts and identify potential entry points for attackers. This involves utilizing various techniques, tools, and methodologies to exploit vulnerabilities and gain access.
  • Security Analysis: Analyzing the results of penetration tests to assess the severity of identified vulnerabilities, their potential impact on the system and the business, and the likelihood of exploitation.
  • Reporting and Documentation: Preparing detailed reports that document the findings, including identified vulnerabilities, attack vectors, and recommendations for remediation. These reports typically outline the risks associated with each vulnerability and provide guidance on how to mitigate them.
  • Remediation Support: Collaborating with developers and system administrators to assist in the remediation of identified vulnerabilities. This may involve providing guidance on secure coding practices, recommending security controls, or validating the effectiveness of implemented fixes.
