PSM : IGEL’s Blueprint for Preemptive Protection

At a time when “detect and respond” has become the norm in cybersecurity, IGEL is turning the tables. The Preventive Security Model (PSM) is not about chasing incidents, but eliminating their possibility. It is a security philosophy designed to prevent, not just endure.

The “Why”, From Reaction to Resilience

At its core, the Preventive Security Model (PSM) is IGEL’s response to a systemic problem: complexity has become the enemy of security. The more tools, agents, and patches a company accumulates on a device, the larger the attack surface becomes. PSM shifts the focus from endless detection cycles to a prevention-oriented approach.

Instead of relying on reactive layers of defense, the model asks a fundamental question: “What if the endpoint itself couldn’t be compromised?”

This question is at the heart of the entire model and leads directly to the design of the Preventive Security Architecture that implements it.

The “How”, The Architecture that Embodies the Model

If the model is the “why”, Preventive Security Architecture (PSA) is the “how”.
This architecture applies the IGEL model philosophy through concrete mechanisms:

• Immutable kernel: a read-only operating system that reboots each time in a known and reliable state.
• No local data: eliminates the risk associated with data at rest, significantly reducing the impact of ransomware.
• Trusted application platform: only signed and verified software runs, ensuring a zero-trust posture at the device level.
• Centralized control via Universal Management Suite (UMS): All endpoint policies, updates, and configurations are applied from a single console.
• Native encryption + TPM-backed chain of trust: Hardware-anchored integrity ensures authenticity from boot to user session.

Together, these elements enable prevention, a system in which attack surfaces are minimized, persistence is impossible, and policies replace patches.

The Outcome, Adaptive Secure Desktop: The Workspace Reimagined

The Adaptive Secure Desktop (ASD) is the meeting point between IGEL’s Preventive Security Model (PSM) and Preventive Security Architecture (PSA) and the user experience. It embodies the prevention-focused approach: a workspace that adapts to each user while remaining secure and immutable.

ASD does more than just provide desktops, browsers, and applications. It offers certainty. Each session starts in a clean and reliable state, free of residue, risks, or malicious processes. Users access virtual desktops, SaaS applications, or local browser applications through a consistent, policy-based interface managed by IT.

Key outcomes:

• Zero trust access: ASD validates identity, integrity, and intent before connecting users to applications or data. This enables the principle of least privilege to be applied at the edge.
• Workspace flexibility: Simultaneously supports VDI, DaaS, and SaaS models, connecting traditional and cloud-native delivery models under a single secure access point posture.
• Continuous compliance: With every reboot, ASD resets to a known and trusted configuration. Compliance becomes a default state, not an audit exercise.
• Operational simplicity: IT benefits from centralized orchestration via the Universal Management Suite, which controls configuration, updates, and security posture without agents or manual patches.
• Freedom for users, control for administrators: ASD enables dynamic workspace policies based on role, device, or location, allowing clinicians, engineers, or remote staff to work securely without the traditional IT burden.

In essence, ASD transforms policy prevention into a daily experience, where each session starts from scratch, each access is verified, and each terminal remains reliable.

Why It Matters Now, From Resilience to Regulation

Cyber resilience is no longer optional. Mandatory frameworks such as NIS2 and NIST CSF2 have elevated security from a technical issue to a governance imperative. The preventive security model positions IGEL at a crossroads.

Traditional endpoint strategies rely on sprawling tool chains (EDR, DLP, patch managers, and antivirus) that are added reactively. IGEL flips this dogma on its head: an immutable, centrally controlled operating system that eliminates vulnerabilities before they manifest.

Why is this important today?

• Speed of threats: Attacks happen in seconds. Prevention must occur at the millisecond level, at the operating system itself.
• Complexity fatigue: Every new agent adds friction. IGEL reduces stack proliferation, simplifying defense and management.
• Regulatory urgency: From ransomware incidents to compliance audits, prevention-focused design meets the demand for verifiable resilience.
• Business continuity: With built-in dual boot and instant recovery, downtime is reduced from hours to minutes, meeting new resilience standards.

The result: a unified endpoint platform that is not only secure, but also compliant by design.

From Boardroom to Baseline (NIS2 & Governance Readiness)

With the NIS2 standard shifting responsibility for IT cybersecurity to executives, prevention is no longer an option but a governance requirement. Boards of directors must ensure that risks are mitigated before they materialize, not simply reported after an incident has occurred.

IGEL’s Preventive Security Model fits perfectly with this evolution.

• Assurance at the board level: Article 21 of the NIS2 Directive requires “appropriate and proportionate technical and organizational measures”. IGEL’s immutable architecture, with its “no local data” principle, provides verifiable, directly auditable, and instantly demonstrable evidence of control.
• Cross-functional governance: PSM simplifies the governance chain. Security, IT, and compliance teams operate on the same management plane (via Universal Management Suite), where the status of each endpoint is known, controlled, and compliant.
• Policy over patches: By centralizing configuration and removing modifiable layers, PSM translates cybersecurity policy into an enforceable and immutable reality.
• Reduced audit overhead: Each restart restores compliance, meaning audit evidence is built into operations. Compliance ceases to be a one-time event and becomes the default state.

IGEL transforms cost center compliance into a continuously verified state of trust.

In short:
Adaptive Secure Desktop is prevention you can touch and see. The Preventive Security Model is compliance you can trust. Together, they redefine what it means to be ready, not only for the next breach, but also for the next regulation.
