Zero Trust Solutions That Put You in Control

In today’s cybersecurity landscape, threats are more sophisticated, persistent, and unpredictable than ever. Traditional security models that rely on perimeter defenses and reactive detection are no longer enough. That’s why forward-thinking organizations are adopting Zero Trust: a security framework built on the principle of “never trust, always verify.”

Zero Trust is a mindset. And the most effective way to implement it? Application Allowlisting.

At LeeShanok, we use allowlisting to protect your systems from unauthorized software and ransomware. By working together, we help ensure your environment stays secure, resilient, and under your control.

What Is Zero Trust?

Zero Trust is a modern cybersecurity approach that assumes no user, device, or application should be trusted by default. whether inside or outside your network. Instead, access is continuously verified, and every action is governed by strict, context-aware policies.

This model shifts security from a perimeter-based mindset to one that treats every access request as potentially hostile until proven otherwise. It’s designed to reduce risk, limit exposure, and contain threats before they spread.

Core principles of Zero Trust include:

Click on each box to learn more.

Enforce strong authentication and least-privilege access. Only the right users get the right access—nothing more.

Limit lateral movement by isolating systems and verifying device health before granting access.

Track user behavior and system activity in real time to detect and respond to threats quickly.

Protect sensitive data and applications wherever they live—on-prem or in the cloud.

Inspect and control all traffic with advanced tools like firewalls, ZTNA, and intrusion detection.

Our Zero Trust Solution: Application Allowlisting

To bring Zero Trust to life, we use Application Allowlisting. It’s a proactive, deny-by-default strategy that ensures only explicitly approved applications, scripts, and executables can run in your environment.
Rather than trying to detect threats after they’ve launched, allowlisting prevents unauthorized software from executing in the first place.

Why Allowlisting Works

Application Allowlisting is a proactive, deny-by-default strategy that stops threats before they execute. Unlike traditional antivirus solutions that rely on detecting known malware, allowlisting prevents both known and unknown threats from running, making it a powerful tool for enforcing Zero Trust.

Here’s why it works so effectively:

  • Prevents ransomware, zero-day attacks, and both known and unknown malware from launching.

  • Only approved applications are allowed to run, minimizing exposure to shadow IT and reducing security incidents by up to 99%.

  • Enforces least privilege and removes local admin rights, limiting the potential for internal misuse.

  • Firewall-like policies let you permit, deny, or restrict application access at a detailed level, with real-time approvals and time-based access options.

  • Built-in application definitions include all dependencies and updates, simplifying setup and maintenance.

  • Security teams spend less time on routine tasks like maintenance, auditing, cleanup, and response—resulting in labor efficiency gains of up to 50%.

  • Clear visibility into application behavior and access supports regulatory requirements like HIPAA, GDPR, and ISO/IEC 27001.

How It Works
