Our Cyber Penetration Testing service analyses the security of your IT systems by recognising and exploiting weaknesses. This involves profiling your organisation from the perspective of its most likely threats, business processes, and technology that supports your operations.

We do not use scanning tools such as vulnerability assessment tools as attack scenarios can be overlooked. We use tools similar to those used by attackers on the internet and tools that are developed in-house.


Our cyber penetration testing looks at the following:

  • Operating System Security
  • Application Security
  • Wireless Security Penetration
  • Remote Access Testing
  • Social Engineering Testing
  • Red Team Penetration Testing


NSI’s Governance, Risk and Compliance services provide a unique approach to the management and governance of information security.


We will assess your company’s:

  • Policies and Procedures
  • Alignment with ISO Standards (27001, 27005, 31000)
  • PCI Data Security
  • Alignment with Australian Government Security Standards (ISM, PSPF)
