Given the complex and multi-faceted nature of a CSA, it is highly recommended that you hire a third-party to complete your assessment. A third-party organization engages a myriad of skills, experience, tools and technologies to conduct the CSA. This combination is customized to meet the agreed upon scope of the CSA.
Also, a third-party perspective is always helpful because it gives an unbiased view of the security posture of your organization. Third-party companies will provide you with a thorough detailing of their findings so that your company’s IT and Information Security team can get to work eliminating any potential risks. In addition, the findings can be used to develop new security policies and provide supporting evidence for existing ones.
