Attack and Penetration

Identify and remediate vulnerabilities to protect critical assets

Protiviti’s attack and penetration services protect sensitive data and systems, helping to avoid costly breaches, intellectual property loss, business disruption, and reputation damage. With the expanding threat landscape, it is critical to understand security vulnerabilities, their root causes, and remediation options.

Using our advanced penetration testing expertise, we identify vulnerabilities and provide actionable remediation guidance. Assuming an “attacker mindset” to replicate any scenario, we leverage best-in-class commercial security tools, leading freeware, the top open-source tools, and the latest penetration testing techniques.

Applications, services, databases, the Internet of Things (IoT), and mobile devices, whether on-premise or in the cloud, are safer with Protiviti.

Simulating a bad actor, we identify vulnerabilities by using physical, electronic, and telephonic methods to target employees and facilities, gaining access to data and networks.



Our innovative approach

Our innovative methodology is led by threat intelligence, and it centers around holistically understanding risk to the organization. Our comprehensive approach to performing security assessments goes beyond merely identifying vulnerabilities.

Protiviti’s custom methodology mirrors several industry standards, such as the Penetration Testing Execution Standard (PTES) and Open Web Application Security Project (OWASP), to determine and validate root causes of identified issues, and collaboratively work with organizations to develop recommendations that best fit their environments.
