Application Containment and Ringfencing for Zero Trust

🔒 Ringfencing, or granular application containment, enforces least privilege for authorized software by restricting file, registry, network, and interprocess access. It complements allowlisting by preventing misuse of trusted tools that attackers commonly weaponize, such as scripting engines and archivers. Effective rollout uses a monitoring agent, simulated denies, and phased enforcement to minimize operational disruption. Properly applied, containment reduces lateral movement, blocks mass exfiltration and ransomware encryption while preserving business workflows.

ThreatLocker Adds macOS Configuration Scanning Beta

🔒 ThreatLocker has released DAC for macOS in Beta, extending its configuration-scanning capability to Apple endpoints. Using the existing ThreatLocker agent, the feature can scan Macs up to four times daily and surface risky settings—FileVault, firewall, sharing/remote access, admin accounts, Gatekeeper, update policies—directly in the same console used for Windows. Findings are grouped by endpoint and category and include step-by-step remediation plus mappings to frameworks such as CIS, NIST, ISO 27001, and HIPAA. The aim is to make misconfigurations visible and remediable before they become security incidents.

Secure-by-Default: Simple Defaults to Shrink Attack Surface

🔒 This article argues that adopting a security-by-default mindset—setting deny-by-default policies, enforcing MFA, and employing application Ringfencing™—can eliminate whole categories of risk early. Simple changes like disabling Office macros, removing local admin rights, and blocking outbound server traffic create a hardened environment attackers can’t easily penetrate. The author recommends pairing secure defaults with continuous patching and monitored EDR/MDR for comprehensive defense.

Microsoft Tops Modern Endpoint Security Market Share

🔒 Microsoft Defender has been ranked number one in modern endpoint security market share for the third consecutive year, according to IDC’s 2024 report. Market share rose from 25.8% in 2023 to 28.6% in 2024, reflecting a 28.2% growth rate. Defender emphasizes cross-platform protection—Windows, macOS, Linux, iOS, Android, and IoT—leveraging AI-powered detection and built-in exposure management to enable rapid SOC response and attack disruption.
