External Network Testing

At Precursor, we understand the importance of your external public facing network and the negative impact security breaches may have on a company. We collaborate with our clients to protect their external networks from a variety of cyber threats.

What is External Network Testing?

External network penetration testing is a proactive and systematic evaluation of an organisation's externally facing infrastructure, including servers, routers, firewalls, and other internet-accessible devices.

By conducting regular external network penetration testing, organisations can stay ahead of evolving cyber threats and maintain a robust security posture. This proactive approach enables them to address vulnerabilities before malicious actors can exploit them

  • Insecure Configuration of exposed systems resulting in decreased security for both users and the organisation
  • Exposed Services that can leak data or provide unintended network or data access
