Inside a Penetration Test: How Ethical Hackers Uncover Hidden Vulnerabilities to Protect Your Business
CyberGuard Security outlines a structured penetration test—from scoping and written authorization to recon, targeted scanning, controlled exploitation, cleanup, and a practical, risk-based report that prioritizes fixes. It translates findings into defenses with quick wins like MFA adoption, CVE patching, and firewall tightening, plus longer-term measures such as network segmentation and secure configurations, followed by remediation planning, retesting, and a complimentary consultation to start.

This 2025 guide shows how to build a robust firewall posture by moving beyond port blocking to policy enforcement, network segmentation, zero-trust remote access, and stateful IPS/IDS protection with default-deny rules and identity-based access. It also emphasizes continuous defense through centralized logging to SIEM, smart anomaly alerts, vulnerability management, backups, and incident response automation to rapidly detect and contain ransomware.
