Best Penetration Testing Companies in Sydney, NSW
Find and compare verified penetration testing providers serving Sydney businesses. Penetration testing — or pen testing — involves authorised ethical hackers attempting to breach your systems using the same techniques as real attackers. The goal is to find exploitable vulnerabilities before criminals do, and to produce a report that prioritises and guides remediation. In Australia, pen tests are increasingly mandated by compliance frameworks including the Essential Eight, ISO 27001, and APRA CPS 234.
Sydney is Australia's largest commercial hub and has the highest concentration of cybersecurity providers in the country. Competition is strong, which means buyers have more choice — but also more due diligence to do.

How much does penetration testing cost in Sydney?
Pen test pricing in Australia typically ranges from $5,000–$15,000 for a single web application, $15,000–$40,000 for an internal network assessment, and $50,000–$150,000+ for a full red team engagement. Always get a fixed-price quote scoped to your environment.
What certifications should a penetration testing provider in Sydney hold?
CREST accreditation is the benchmark for pen testing in Australia. For federal government work, providers must hold current IRAP assessor status. Check the CREST Australia register before engaging any firm.
What industries in Sydney most need penetration testing services?
Sydney's economy is driven by financial services, insurance, fintech, and ASX-listed companies, all of which face significant cyber risk. Regulated sectors — particularly those subject to APRA CPS 234 and the Privacy Act 1988 — have the most pressing compliance-driven requirements.
How often should we run a penetration test?
Most compliance frameworks recommend at least annually, plus after any major infrastructure change, application release, or security incident. High-risk environments (financial services, government) often test quarterly.
What is the difference between a vulnerability scan and a penetration test?
A vulnerability scan is automated and identifies known weaknesses. A penetration test involves a human tester actively exploiting vulnerabilities to demonstrate real-world impact. Scans are faster and cheaper; pen tests are deeper and more meaningful for compliance.
