GDPR Compliance
GDPR-compliant data handling for all IT systems and processes — critically important for a firm managing sensitive financial data for private clients and businesses.
Secure IT for a Data-Sensitive Industry
Tax consulting firms operate in one of the most data-sensitive sectors in any economy. Client financial data, tax declarations, bank statements, and business records are subject to strict confidentiality requirements under both professional regulations and GDPR. A single data breach or compliance failure can be catastrophic — both legally and reputationally.
At the same time, a small tax consulting firm cannot afford to have in-house IT expertise. Managing IT in-house would divert critical attention and resources away from the firm's core mission of providing excellent tax advice. What Steuerberater Keller needed was a trusted, proactive IT partner who could handle everything — reliably, securely, and without requiring constant input from the firm's team.
GDPR & Data Protection
All IT systems and data handling processes must be fully GDPR-compliant — covering data storage, access controls, retention policies, and incident response procedures for sensitive client financial data.
