ShellNewHandler VS ThreatLocator

No features have been listed yet.

• Default-deny application allowlisting
  ThreatLocker blocks anything not explicitly approved, which stops unknown executables, ransomware, and other zero-day malware that signature-based tools can miss. This is the core of its Zero Trust approach.
• Granular Ringfencing controls
  Ringfencing limits what approved applications can do, such as accessing files, the registry, the network, or other applications. This reduces the risk of living-off-the-land attacks and abuse of tools like PowerShell.
• Broad control suite in one platform
  Beyond allowlisting, it offers Storage Control, Network Control (dynamic ACLs), Elevation Control, Configuration Manager, and Detect (EDR-style alerting). This lets organizations consolidate several security functions under one agent and console.
• Learning mode and unified auditing
  A learning mode observes normal activity and auto-builds baseline policies, which speeds up rollout. The unified audit log gives detailed visibility into what ran, what was blocked, and why.
• Strong onboarding and support
  ThreatLocker is widely praised for responsive, hands-on support and onboarding help, including a 24/7 operations team and training resources. It also has strong MSP features such as multi-tenant management.

Possible disadvantages

• Steep learning curve and setup effort
  Building and tuning allowlist policies takes time and expertise, especially in complex or diverse environments. Poorly planned deployments can disrupt business applications.
• Ongoing administrative overhead
  Software updates, new tools, and user requests mean policies need continual maintenance and approval workflows. Smaller IT teams may find this burdensome.
• User friction
  Default-deny can block legitimate software and frustrate employees until approvals are processed. This can hurt productivity if approval turnaround is slow.
• Cost for smaller organizations
  Per-endpoint licensing across multiple modules can add up, and some features are sold as add-ons. Small businesses with limited budgets may find it pricey compared with traditional antivirus.
• Not a complete replacement for other security tools
  ThreatLocker focuses on prevention and control rather than being a full EDR/XDR with deep threat hunting and response. Most organizations still need complementary tools, and macOS and Linux support is less mature than Windows.

• I recently got libreoffice, but now the new option in right click looks like a mess. Can someone help me get rid of them please?

  Use Shell New Handler. Run the portable app and simply untick the items you don't want to appear in your new context menu. Source: about 4 years ago

• This menu should be easy to add/remove programs to... Who is really creating Access Databases from this menu often enough to keep it here? (Not me!) Is there an easy way to edit this?

  I've always used ShellNewHandler for this. It's a really simple portable utility that allows you to remove most of the items from that menu. Tested it out on Windows 11 and it's still compatible. Source: over 5 years ago
