New Tool Enhances MacOS Security Against Configuration Weaknesses

Menlo Park, California – ThreatLocker has launched a new feature for macOS aimed at improving security by identifying misconfigurations. The newly named Defense Against Configurations (DAC) addresses vulnerabilities that often go unnoticed within organizations, even those that prioritize cybersecurity.

Misconfigurations in software settings can provide open doors for cyber attackers. For example, when a design firm uses an app that quietly accesses the microphone and camera on a MacBook Pro, the necessary permissions should ideally trigger an alert from macOS. However, existing checks can be lax, and in some cases, apps gain unauthorized access.

On another Mac in the office, the use of the outdated SMB version one protocol for file sharing adds to the security issues. While this method is fast and convenient, it is also known to be easily exploitable if the endpoint is exposed to the internet.

ThreatLocker’s DAC tool aims to make vulnerable configurations visible on macOS systems before they can be exploited. Following a previous release for Windows in August 2025, ThreatLocker’s latest tool allows macOS users to scan for risky settings up to four times a day, live within the ThreatLocker dashboard they already use.

The initial beta focuses on high-value security controls, providing insights grouped by endpoint and category. Each finding includes remediation guidance and alignment with major security frameworks like CIS, NIST, ISO 27001, and HIPAA.

Design firms and media studios, which often rely on powerful macOS systems for their workflows, can particularly benefit from this added visibility. Weak spots identified can include unencrypted drives, disabled firewalls, and permissive sharing settings.

Moreover, DAC connects security findings to ThreatLocker policies for streamlined remediation. This added visibility is intended to help organizations comply with security frameworks and meet insurance requirements effectively.

As cyber threats evolve, the need for real-time insight into security configurations becomes increasingly essential. DAC presents itself as a practical solution to empower IT and security teams with actionable data.
