External Network Penetration Testing

What is external network penetration testing?

An external network penetration test is used to detect vulnerabilities and security issues in a network that could be exploited by criminal hackers.

It involves identifying vulnerabilities, attempting to exploit them, and providing a report with risk and remediation advice.

xternal network penetration tests use advanced techniques and automated scans to identify risks within a business by simulating real-world attacks. They cover:

  • Secure configurations
  • Network traffic
  • Secure passwords
  • Patching
  • Secure authentication
  • Encryption
  • Information leakage

If you are responsible for your external network, you should ask yourself:

  • Are my systems fully patched and properly configured?
  • Are any systems or applications secured with weak or default passwords?
  • Have I accounted for all the services exposed to the Internet?
  • Could malware be present on my system?
  • Is every device secured by a correctly configured firewall?
