BSI Culture of Security

Ensuring the safety, security and confidentiality of your payroll data is our utmost priority. BSI takes great pride in making sure that your sensitive information is safe with us.

BSI takes various steps to minimize the possibility of security breaches. We configure our software to limit access to confidential data and help protect it from both external and internal threats.  BSI relies on data centers which offer built-in redundancies that are important for protecting sensitive account data. Each BSI payroll tax suite prompts users to change their password regularly (and encourage responsible password creation) to reduce the risk of password hacking.

BSI Has Passed SOC 2® Type 2 Audit and Has SOC 3 Report

Service Organization Control (SOC) Reports
The Service Organization Control (SOC) 2 Type 2 report was developed by the American Institute of Certified Public Accountants (AICPA) to perform an in-depth audit of a service organization’s controls. The SOC 2 Type 2 report provides strict audit requirements and sets a high bar for a more meaningful audit standard. The completion of this audit verifies that BSI’s information security practices, policies, procedures and operations meet the SOC 2 standards for security for BSI’s SaaS services. BSI also has the SOC 3 report available.
