Secure your organization’s network with expert penetration testing from reconnaissance to remediation
Reconnaissance:
Gathering insights
Mapping out your network, identifying vital elements like IP addresses and open ports to inform targeted testing.
Manual & automated scans:
Uncovering vulnerabilities
Using both cutting-edge tools and a hands-on approach to pinpoint vulnerabilities, ensuring no blind spots are left unaddressed for potential exploits.
Exploitation:
Attack simulation
Simulating real-world attacks to pressure-test your system, identifying weak areas requiring immediate attention.
Post-exploitation:
Testing resilience
Evaluating network resilience by solidifying access via backdoors, stealth accounts, and log alterations.
Reporting & remediation:
Actionable insights
Delivering a focused report on vulnerabilities and remedies, followed by a reassessment to confirm enhanced security.
