Recent Feedback

“CommSec provided an excellent service from beginning to end. They also provided us with a comprehensive and useful report. They worked seamlessly with our other vendors. I would have no hesitation in recommending them to any organisation that is looking for a cost-effective and comprehensive Pen Test”

Risk & Compliance Officer @ Affinity CU

We searched the market looking for a comprehensive IT penetration test provider and chose Commsec based on their pedigree as a Cyber Security provider. The tests itself was quick and we wouldn’t have even known it was happening! The final report was easy to understand and the lads were more than helpful in explaining any remediation.

IT Manager @ JVaughan Electrical

I just wanted to thank you and your team for the very professional job you did for us on the recent PEN Test. We look forward to working with you again in the future
