Modernizing Endpoint Security for Resilience and Scalable Operations

For more than a decade, cybersecurity strategies have primarily focused on improving the speed of detecting compromises. Today, however, the core challenge extends beyond detection. It lies in how endpoints are designed, managed, and controlled.

Over time, organizations have added multiple layers of technology, including EDR, MDR, XDR, threat intelligence, and AI-driven analytics, resulting in increasingly complex security architectures.

While these capabilities are critical, the continued expansion of tooling has not reduced systemic risk. At the same time, organizations are adopting new workspace models, including SaaS and browser-based access, creating a need for more controlled and adaptable endpoint environments.

This situation is not the result of insufficient expertise. On the contrary, security teams are highly skilled. The underlying issue is that a fundamental layer is often not sufficiently reconsidered: the endpoint.

Why the German market cannot ignore this shift

Germany represents one of Europe’s largest and most industrialized economies, with a highly interconnected digital and manufacturing base. The continued expansion of cloud adoption, digital infrastructure, and connected systems has improved efficiency, while also increasing systemic exposure.

This development is reflected in the current threat landscape.

The Federal Office for Information Security (BSI) assesses the cybersecurity situation in Germany as “tense to critical,” with both the number and sophistication of attacks continuing to increase.

Ransomware remains one of the most disruptive forms of attack, affecting businesses, public sector organizations, and critical infrastructure. Recently, BSI reported that an average of 309,000 new malware variants are detected every day, highlighting the industrialized nature of modern cyber threats. Furthermore, Germany’s Federal Criminal Police Office (BKA) found that approximately 950 ransomware attacks were reported in 2024, which is the equivalent of two to three serious incidents per day, affecting businesses, public sector organizations, and critical infrastructure.

At the same time, cybercrime is becoming increasingly organized and industrialized, with scalable attack models lowering barriers for threat actors.

The economic and operational impact is significant. Cyber incidents are now a material business risk, affecting continuity, financial performance, and regulatory exposure.

Risk is not evenly distributed. Public sector organizations, critical infrastructure operators, and healthcare providers are among the most frequently targeted due to the essential nature of their services. In parallel, small and medium-sized enterprises remain particularly exposed, often lacking the same level of endpoint control and recovery capabilities.

Attack methods are also evolving. The combination of encryption, data exfiltration, and extortion has become increasingly common, placing additional pressure on organizations to respond quickly and effectively.

This environment is further shaped by regulatory developments:

• The NIS2 Directive, now being implemented in Germany, expands cybersecurity obligations across sectors
• The Digital Operational Resilience Act (DORA) introduces stricter requirements for resilience and recovery in financial services
• National priorities around digital sovereignty and infrastructure protection emphasize control, transparency, and operational independence

In summary, the direction is clear: cybersecurity in Germany is no longer solely characterized by prevention; it is progressively centered on resilience, control, and the capacity to sustain operations amidst persistent threats.

For large enterprises, public sector organizations, and healthcare providers, this creates a requirement for solutions that not only reduce risk but also support scalable operations, regulatory compliance, and long-term platform standardization.

Why the current model falls short

Most endpoint security strategies are based on the assumption that compromise cannot be fully avoided. This assumption is closely linked to the design of endpoints as open and flexible systems supporting a wide range of use cases.

This challenge is particularly relevant in environments where virtual desktop infrastructure (VDI) is already in use. While VDI centralizes workloads, complex and unmanaged endpoints can still introduce risk, increase operational effort, and limit overall efficiency.

This flexibility introduces additional complexity and increases the attack surface.

As a result, organizations are operating in environments where:

• Attack methods are scalable and increasingly automated
• System complexity limits visibility and control
• Multiple endpoint agents are required to manage risk
• Recovery processes remain time-intensive and resource-heavy

These factors lead to a structural imbalance: complexity increases faster than control.

Adding additional tools does not address this issue. Instead, it often reinforces it.

The shift toward operational resilience

Organizations in Germany are increasingly adopting an approach that focuses on operational resilience rather than prevention alone. This reflects both regulatory requirements and practical experience.

Key priorities include:

• Maintaining continuity during disruption
• Ensuring fast and reliable recovery
• Reducing system complexity and operational overhead

To achieve this, organizations are reassessing the role of the endpoint.

Rather than securing highly flexible environments, the focus is shifting toward controlled and standardized endpoint configurations.

By replacing general-purpose endpoints with secure, read-only, and immutable operating system environments that are centrally managed, organizations can:

• Significantly reduce attack surface
• Enforce consistent security policies
• Eliminate persistence and unauthorized change
• Enable fast, reliable recovery at scale

This approach reduces dependence on multiple endpoint agents while simplifying management and improving consistency.

By ensuring that only explicitly authorized applications and services can be executed, it aligns with Zero Trust principles and establishes a more controlled and predictable operating environment.

In practice, this results in reduced operational effort, faster recovery, and improved visibility across the endpoint environment.

In addition, centralized endpoint control directly supports Germany’s focus on digital sovereignty, enabling organizations to manage dependencies, data access, and system behavior more effectively.

This model also improves real-time visibility and control across endpoint environments, enabling more effective monitoring, policy enforcement, and incident response.

Customer example: German technology services provider

This approach is already demonstrating measurable value in practice. One example is

DAVASO GmbH, a leading technology provider and service provider for statutory health insurance companies and other players in the healthcare market.

By switching to IGEL, DAVASO established a modern endpoint infrastructure that meets the most demanding requirements. With streamlined management, strong security, and seamless processes, the company can focus on what it does best: developing innovative services and driving the digital transformation of the healthcare sector.

“With IGEL, we have found a partner that optimally supports our endpoint strategy. Centralized management via the IGEL UMS saves us a lot of time, and the endpoints with IGEL OS deliver outstanding performance, scalability, security and flexibility,” said Paul Hahn, IT System Administrator, DAVASO.

From flexibility to control

In addition, this approach can be extended to support a broader range of use cases, including secure access for distributed workforces, shared devices, and specialized environments beyond traditional VDI deployments.

Organizations are increasingly adopting a simple principle: only what is required should be allowed to run.

In practice, this means:

• Applications and services must be explicitly authorized
• All non-approved activity is blocked by default

Reducing persistence leads to several outcomes:

• Lower probability of successful compromise
• Restricted lateral movement within the environment
• Reduced impact of security incidents
• Faster and more measurable recovery

Security effectiveness is therefore no longer defined solely by detection speed. It is determined by the ability to maintain control and ensure continuity under adverse conditions.
