What is Data Flow Analysis (DFA)?

Data Flow Analysis (DFA) is a powerful cybersecurity technique used to map and assess how data moves throughout your organization. By analyzing data flows, we can identify potential vulnerabilities, improve data protection strategies, and ensure compliance with global data privacy standards, including SOC2, ISO27001, ISO 42001, GDPR, HIPAA, and HITRUST.

Key Benefits of Data Flow Analysis

  • Identify Vulnerabilities
    Uncover risks associated with the movement of sensitive data, and identify insecure data pathways.
  • Secure Data Transmission
    Ensure your data transmission is encrypted and fully protected, minimizing the risk of breaches.
  • Monitor Third-Party Data
    Keep track of sensitive data shared with third-party APIs, ensuring third-party interactions don’t compromise your security.
  • Establish Security Measures
    Pinpoint critical data flow dependencies and prioritize security efforts to enhance protection where it's needed most.

Data Flow Analysis Phases

Our Data Flow Analysis process is divided into two key phases: Data Flow Questionnaires and Data Flow Interviews. This structured approach allows us to gather in-depth insights into how sensitive data is handled within your organization.

  • Data Flow Questionnaires
    We will send customized questionnaires to 30-50% of your organization’s employees. These questionnaires will be designed to take 10-15 minutes to complete and will gather essential information about how sensitive data is used, stored, and transmitted across your company.
  • Data Flow Interviews
    Based on the questionnaire responses, we’ll conduct 10-15 minute interviews with 1-2 representatives from each department that handles sensitive data. These interviews provide deeper insights into potential vulnerabilities and data flow processes.

Data Flow Process

Our Data Flow Analysis process is designed to ensure seamless communication and efficient execution. Here's a step-by-step overview:

  • Client Completes Approval Form: Provide us with a list of users who handle or transmit sensitive data. We recommend a thorough representation, ideally 30-50% of your team, with 4 or more users from each department.
  • Client Provides List of Users for DFA Questionnaire: Submit the names, emails, and departments of the users who will complete the questionnaire.

We provide a template for you to send to your management team, notifying them about the DFA process.

  • We will send an initial questionnaire email to all selected users.
  • Reminder emails will be sent to users who haven’t completed the questionnaire.

Based on questionnaire answers, we will select interviewees and submit the list to your management team for approval.

We will schedule and conduct 10-15 minute interviews with the selected users to gain deeper insights into data flow and security processes.

After collecting data from the questionnaires and interviews, we will compile the results into a comprehensive Executive Summary. This summary will outline key findings and security risks, as well as actionable recommendations to enhance your data security.

Client Onboarding Responsibilities

To ensure a smooth and effective DFA process, we require the following from your organization:

  • Gather User List

    Provide a list of users who store or transmit sensitive data across your departments.

    For organizations with fewer than 20 users, please include all employees. Ensure the list includes their names, email addresses, and departments.

  • Complete the DFA Approval Form

    Check your email for the Data Flow Questionnaire Approval Form. Complete the form and submit the list of participants and their email addresses.

  • Send Management Email

    After your approval, we will send you a template for the management email. Please forward it to your management team to initiate the next steps.

  • Alert Securis360

    Once the management email has been sent, alert our team. We will start the email process within 2 business days of receiving the notification.
