What others Say
I undertook Pentagram’s eLearning course Security Maturity Assessment and Evaluation for a Critical Infrastructure Risk Management Program – A practical guide. The lessons provided a solid basis for conducting our organisation’s CIRMP assessment and evaluation. More importantly it improved the engagement of functional stakeholders by shifting the focus to maturity and improvements.
The eLearning course reinforces the solid foundations and insights/foresights provided in the regular workshops conducted by Tim and Marina.
The workshops and assessment tools have been an excellent addition to our SOCI compliance toolkit and we look forward to continuing the journey with the valuable support available from Pentagram Advisory.

Pentagram Advisory is a shining exemplar of collaboration in the way you serve the Insider Threat-related needs among Australian critical infrastructure organizations and the network of interdependent groups in the Australia-Pacific region.

Pentagram Advisory brought a high level of professionalism and deep subject matter expertise when they engaged with our organisation whilst developing the SOCI (CIRMP) Maturity Model. From the outset, they demonstrated a strong understanding of the SOCI Act and quickly built rapport with key stakeholders across the business.
Their structured and insightful approach enabled us to identify and close critical gaps in our security posture. More importantly, their work has sparked meaningful conversations across the organisation and has been instrumental in shifting our mindset from “it won’t happen to us” to “it will happen to us unless we change.”
Thanks to Pentagram’s guidance, we are now on a clearer path toward embedding a security culture that stands shoulder to shoulder with our safety culture. Their contribution has been a catalyst for change, and I’m grateful for their support in helping us navigate this important journey.
Thank you, Pentagram, for helping us chart a new course.

Pentagram’s online course on Supply Chain Risk Management was a valuable tool that clearly articulated the key components that need to be considered when managing complex supply chains.
The course allowed me to ensure that a fit-for-purpose framework could be defined for our business.

Glad to see some SOCI evangelists out there!
We have found Pentagram’s eLearning Hub Advanced membership incredibly valuable.
The tailored coaching sessions from Tim and Marina, along with the clear action plans that followed, have been extremely useful in strengthening our CIRMP, supply chain and personnel security, and in meeting our regulatory obligations.
This investment has given our leadership confidence in our CIRMP and overall security posture.

We’ve had the pleasure of working with Tim and Marina from Pentagram on several key security initiatives, and they have been outstanding partners every step of the way.
Whether they were delivering expert briefings on the nuances of insider threats or working hand-in-hand with our team to build our security and risk management plan, their depth of knowledge always shone through. Their most recent project, developing a comprehensive insider threat resource for our members, was delivered to an exceptional standard.
Both Tim and Marina are true subject matter experts, and we would not hesitate to recommend them.

We engaged Pentagram for a short sprint to address an unusual challenge for our organisation. Tim and Marina took the time to understand our needs, they understand the nuances around critical infrastructure security, and they have a deep network to source knowledge from.
I’m satisfied with the quality and delivery of their advice and highly recommend their services.
