Introducing Proactive Hardening and Attack Surface Reduction (PHASR) for Linux and macOS

As Linux dominates cloud-native infrastructure and macOS becomes the standard for high-value targets in development and executive leadership, the attack surface is no longer Windows-centric. Modern attack playbooks weaponize Living off the Land (LOTL) binaries–pre-installed, legitimate system tools–to blend malicious activity with normal operations and bypass standard detection telemetry.

Introducing Extended Email Security

Email remains the primary vector for cyberattacks. Attackers favor "low and slow" tactics—highly targeted spear-phishing, sophisticated brand impersonation, and supply chain fraud.

Master XDR Investigations: A Deep Dive into the GravityZone XDR Demo Incident

Why External Cybersecurity Reviews Reveal What Internal Teams Miss

In today’s threat landscape—where ransomware, phishing, and supply chain attacks evolve faster than most teams can patch—a cybersecurity review isn’t just a checkbox exercise. It’s a critical opportunity to uncover blind spots before attackers do, and it also maps vulnerabilities to business impact, helping teams justify future investments. Rather than reacting to headlines about the latest zero-day exploit, leaders can focus on what truly reduces risk and improves resilience, turning risk into readiness.
