1. Why Leak Monitoring Is Critical

1.1 Leaked Login Credentials as a Point of Entry

Criminals can use leaked login credentials, i.e. particularly combinations of email addresses and passwords, to infiltrate protected systems. While account takeover attacks can already cause significant damage in personal contexts, they often pose an existential threat in a corporat setting.

In corporate settings, login credentials frequently fall into criminal hand through phishing attacks, ransomware, or stealer malware. What is particularly critical is that such incidents often go unnoticed for a long time. Compromised data is subsequently traded or published in relevant forums and can be used directly to gain access to a company’s digital infrastructure.

1.2 Risks Posed by External Platforms and Business Accounts

However, it is not only internal company accounts that are affected. Business email addresses are regularly used for external services, such as supplier portals, or business networks like LinkedIn.

In particular, our 2024 password study (only in German) shows that many employees use their business email addresses for platforms like LinkedIn. If such accounts are compromised, criminals can spread misinformation, place fraudulent orders, or damage the company’s reputation. Another problem is that many of these accounts are not secured by multi-factor authentication.

1.3 Reactive Measures Often Come Too Late

If a data leak is only discovered after an attack has already taken place, the only option left is damage control. Attackers frequently change compromised passwords themselves immediately or are already actively misusing accounts. Deleting or resetting login credentials after the fact is then no longer sufficient.

Therefore, a proactive approach is recommended: Companies should be able to detect as early as possible on whether their employees’ login credentials appear in data leaks before they lead to actual attacks.

2. Leak Monitoring: Protect Your Domain from Data Breaches

2.1 Comprehensive Overview of Compromised Accounts

Targeted leak monitoring enables companies to monitor all email addresses associated with their domain. This provides a comprehensive overview of potentially compromised accounts and security risks within the organization.

Companies are no longer reliant on individual manual checks but instead receive a continuous overview of new incidents and developments.

2.2 Identifying Vulnerabilities and Improving Security Measures

A structured analysis of compromised accounts can help identify internal patterns and vulnerabilities. For example, it is possible to analyze which departments experience a particularly high number of incidents or where there is a need for additional IT security training.

Leak monitoring thus not only helps identify immediate risks but also supports the long-term development of resilient security structures.

2.3 From Reactive Individual Checks of Email Addresses to Proactive Domain Monitoring

There are several ways to check email addresses for compromise. However, checking email addresses one by one is incomplete, reactive rather than proactive, and does not provide a comprehensive picture of the overall situation regarding your own domain:

Continuous monitoring provides transparency into an organization’s overall data breach situation and supports structured security processes.

3. Data Protection & Control: The Advantage of Local Providers

3.1 Data Protection Requirements and GDPR Compliance

From a GDPR perspective, control over personal and business-critical data is becoming increasingly important. Companies must ensure that sensitive information does not end up in third countries without proper oversight or is processed outside clearly defined jurisdictions.

Organizations therefore face the challenge of carefully selecting security solutions and designing audit processes that comply with data protection regulations.

3.2 Data Sovereignty Through Local Solutions

With this in mind, interest in locally operated or self-hosted solutions is growing. These solutions offer greater transparency, improved traceability, and stronger control over sensitive information.

European providers offer particular advantages for German and European companies, as data protection regulations and regulatory requirements are already deeply integrated into the solutions they offer.

4. Leak Monitoring from Germany: The Identeco Approach

4.1 Research as the Foundation for Modern Leak Prevention

Identeco was founded by researchers from the Institute of Computer Science at the University of Bonn. The goal was to translate the findings of a research project on preventing digital identity theft into commercially viable solutions.

As part of this research project, the team investigated how leak data can be processed in compliance with data protection regulations to prevent account takeovers at an early stage. The approaches developed were subsequently refined by Identeco and brought to market readiness.

4.2 Hosting, Development, and Support from Germany

Both development and hosting, as well as data management, continue to take place in the area around Bonn in Germany. As a result, companies benefit from a clear legal framework, short communication channels, and high transparency.

Small and medium-sized enterprises and operators of critical infrastructure, in particular, benefit from locally oriented solutions that can be easily integrated into existing security structures. Additionally, Identeco’s leak monitoring requires no additional implementation effort.

4.3 Identeco as a German Alternative

As a German company, Identeco deliberately positions itself as an alternative to established international services. Its focus is less on global reach and more on data protection, transparency, and digital sovereignty.

As a result, the solution is particularly suited to organizations with high standards for compliance, control, and resilience against cyberattacks.
