What Mein-Datenschutzbeauftragter.de does

Herold Unternehmensberatung GmbH, operating commercially under the brand Mein-Datenschutzbeauftragter.de, is a Germany-based consultancy headquartered in Lübeck that provides outsourced data protection officer (DPO) and information-security services to organizations across the DACH region (Germany, Austria, Switzerland). Founded in 2009, the firm serves more than 400 customers — spanning publicly listed corporates (Varta AG, tonies GmbH), healthcare and non-profit organizations (DRK-Kreisverband Lübeck), SMEs, and public-sector entities — with services across data protection, information security, compliance, and risk management. Consultants operate from a network of 25 German cities, enabling on-site presence for audits, training, and incident response.

The company's product surface combines traditional consulting engagements with a digital tool suite: an e-learning academy that has delivered over 15,000 training sessions, phishing-simulation exercises, website monitoring, a NIS-2 readiness check, and a privacy policy generator. Credentials include TÜV PersCert certification of consultants, FOCUS-BUSINESS "Top Consultant 2023" recognition (third consecutive year), and the "Arbeitgeber der Zukunft 2025" employer award; the firm carries a 4.7/5 rating across more than 200 reviews on the Kununu employer platform.

The business operates on subscription-based annual contracts with an initial trial period, supplemented by free compliance-check tools as lead-generation mechanisms and dedicated practices around emerging EU regulations (NIS-2, EU AI Act, DORA, CRA). The company is privately held with no disclosed external funding, employs 11–50 people, and competes in the DACH regulatory-compliance advisory market on the strength of certified expertise, geographic coverage, and recurring-revenue service contracts.

Emerging players

• Proliance GmbH: German data protection / privacy management software vendor for mid-market and enterprise customers. Comparable as a DPO-software peer with overlapping target market and similar regulatory niche.
• EQS Group: Munich-listed compliance SaaS provider specializing in whistleblowing (Hinweisgebersystem), governance, and compliance workflows — directly relevant for the LkSG/whistleblowing and EU AI Act compliance workstreams Mein-Datenschutzbeauftragter.de offers clients.

Direct peers

• heyData: Berlin-based compliance platform focused on data protection, HR compliance, and ISO 27001 for SMEs. Direct competitor targeting the same German SME buyer with bundled software + advisory, the closest hybrid services-and-software peer to Mein-Datenschutzbeauftragter.de.
• Datenschutz Süd GmbH: Stuttgart-based external DPO and data protection consultancy with a similar SME/corporate customer base in southern Germany. Closely comparable boutique consulting peer with overlapping service lines (DPO outsourcing, GDPR consulting).
• DataGuard: Munich-based data protection and information security SaaS provider serving German SMEs and mid-market. Direct competitor: also offers GDPR/ISO 27001 packages plus digital tools, but as a software-led platform rather than a consultancy — most directly comparable substitute for Mein-Datenschutzbeauftragter.de's DPO + compliance offering.
• Dr. Datenschutz (doctima GmbH): German external data protection officer and information security consultancy serving SMEs and mid-market customers. Closely comparable boutique consulting peer competing for the same German DPO outsourcing and GDPR advisory deals.

Broad incumbents

• TÜV SÜD: Major German certification, testing, and advisory body running ISO 27001, GDPR-related audits, and management-system services. Comparable as a broader, established player operating in the same compliance/audit space with deeper credentialing authority.
• KPMG Germany (Cyber & Privacy practice): Big-4 advisory firm in Germany offering privacy, cyber security, and risk consulting at enterprise scale. Broad incumbent overlapping Mein-Datenschutzbeauftragter.de's advisory services, especially with German Mittelstand and large enterprise customers.
