About Cyber Insight

Cyber Insight is revolutionizing the IT security and regulatory markets with an accessible SaaS solution that enables law firms, IT service providers, management consultants, insurance companies and their clients to identify, manage and mitigate risks.

Cyber attacks cause a total annual damage of 223 billion euros in the German economy, with 88% of companies being affected by malicious attacks. According to our evaluations, a data protection breach costs small and medium-sized companies an average of around €67,000.

The Cyber Insight Platform helps our customers to increase the compliance step by step. Compliance includes both security and data protection standards. The assessment of risks and the derivation of prioritized recommendations for action are based on a multifactorial risk model that takes into account individual vulnerabilities and exogenous factors such as current trends or changes in the legal situation and integrates them automatically into the assessment scheme with the help of AI. The customer thus receives automated security assessments and suggestions for concrete measures, giving them the opportunity to reduce their risk cost-effectively and mitigate damages and penalties before they occur.

The goal is to make cyber risks and regulatory compliance measurable and to enable anyone to adequately address these issues who would previously have been exposed to very high risk due to insufficient capitalization or lack of know-how.
