Strengthening Your Cyber Defense: Introducing ThreatLocker

In today's digital landscape, the threat of cyber attacks looms larger than ever. At On Call, we understand the importance of staying one step ahead of hackers, which is why we're excited to introduce our latest addition to the arsenal of cybersecurity tools: ThreatLocker.

Empowering Your Defense

ThreatLocker isn't just another antivirus program. It's a comprehensive enterprise security solution designed to stop cyber attacks in their tracks by employing a unique approach: allowing only known good programs to run on your system while blocking everything else until approved. This proactive stance sets it apart from traditional antivirus software, which often reacts to malicious activity after it's already begun.

Understanding ThreatLocker's Key Features


Let's delve into the key features that make ThreatLocker an indispensable tool in your cybersecurity arsenal:

  1. Allowlisting: With ThreatLocker, you have the power to allow only approved software to run on your system, effectively thwarting ransomware, viruses, and other unwanted programs from executing.
  2. Ringfencing: Limit the interactions between applications to prevent the weaponization and exploitation of trusted applications, a common tactic used in cyber attacks.
  3. Network Control: Utilize a host-based firewall that dynamically opens and closes ports as needed, preventing rogue devices from gaining unauthorized access to your network.

Embracing Zero Trust Principles

At On Call, we believe in adopting a Zero Trust approach to cybersecurity, which assumes that every system component could potentially be compromised. ThreatLocker's Allowlisting feature operates in alignment with this philosophy, leveraging:

  • Learning Mode: Spend time understanding your system's typical processes, files, and components before establishing a baseline of normal behavior.
  • Dynamic Detection: Automatically update Allowlisting signatures directly from software publishers, ensuring that even sophisticated impersonations of trusted software are detected.
  • Ad-hoc Allowances: Streamline the process of loading new software by allowing direct notification to our team for review and scanning, eliminating unnecessary delays.

Protecting Your Assets, Now and Into the Future

We're committed to safeguarding your IT systems and data, which is why we're planning to deploy ThreatLocker to all workstations and servers under our management. This cost-effective solution is fully managed and provides the protection you need against both known and unknown threats.
