Introduction to External Penetration Testing

Your organisation’s external perimeter is your first line of defence against cyber threats. It includes all internet-facing systems such as web servers, email servers, VPNs, and firewalls—all of which can be targeted by attackers looking for vulnerabilities to exploit.

At IntaForensics, our External Penetration Testing service simulates real-world cyber-attacks to identify and assess weaknesses in your external systems. This proactive approach ensures that your security measures are effective and helps reduce the likelihood of a data breach.

All testing is conducted using a combination of manual and automated techniques, adhering to CREST-certified methodologies, and is non-disruptive, meaning there will be no impact on your daily operations.
