Our Story

Sentaris was founded in 2015 by Justin Waite, who saw a significant gap in the IT Security market. Justin previously spent 16 years in senior management roles in three of Australia’s largest four banks and consumed many security services from different vendors. He found that many services companies lacked the business acumen to appreciate all aspects of security risks, especially went it came to Penetration Testing.

A year later, Frank Virgato joined Sentaris who shared Justin’s vision of a business-focused security services company and helped further develop the Penetration Testing capability. Frank’s previous experience as a senior IT leader further bolsters Sentaris’ ability to provide a business risk lens to IT security problems. Justin and Frank’s aligned vision now sees them as business partners who lead Sentaris in guiding some of Australia’s largest companies.

Today, Sentaris has employees spanning across Melbourne and Sydney who service all Australian states as well as international customers. Responding to the needs of our customers as well as the specialisation of our staff, Sentaris now provides a much more comprehensive suite of Security Services outside of just Penetration Testing.  Even though we have a broader service offering, we still maintain our vision of delivering high quality business-focused services.

Collaboration is at the core of what we do

Collaboration is a critical ingredient when testing in agile environments in order to achieve the best possible outcomes for our clients. We pride ourselves on our ability to nurture a collaborative environment with both technical and non-technical staff to deliver the best results possible.

The Sentaris Approach

Sentaris takes a risk-based, business-centric approach to the delivery of all Penetration Testing services. Our focus is to achieve consistent, practical and positive outcomes for our clients. We base our model around a three-step approach:


Our risk-based approach is predicated on working closely with our clients to develop a deep understanding of their business and business risks. This enables our consultants to identify and prioritise areas exposing the business to the most critical risk.

As a result, our clients receive advice targeting their risk profile and practical recommendations aimed at reducing real-world business risk, whilst keeping both remediation and ongoing security costs down.


Our collaborative approach means we work closely with our clients throughout the entire engagement from beginning to end. We deliver outcomes that match and exceed client expectations that are closely customised to their individual needs.


We use a project-oriented approach based on industry standards to ensure that outputs are delivered:

  • On time
  • To quality standards
  • In the most effective, efficient manner
  • With minimal business disruption for clients.
