What is the PentestOps Knowledge Centre?
It is a library of practical, technical explainers on offensive security: how penetration testing actually works, what the major standards ask for, and how to reduce real exposure across applications, networks, identities and clouds. Each guide is written for practitioners and for the people who have to fund or approve their work. Start with what is penetration testing for the foundations, or go straight to a standards guide such as PTES explained.
Who writes these guides?
The security engineers and practitioners who build and operate PentestOps at Extranet Systems Pty Ltd, an ISO/IEC 27001:2022 certified Australian technology company. The material comes out of running the platform and doing the work, not from a content agency. Where a guide describes a published standard, it follows that standard rather than our product.
Are the guides vendor-neutral?
Yes. Each article explains its topic on its own terms and does not name or rank third-party scanning tools. Where PentestOps is genuinely relevant it appears in a clearly separated section at the end, so you can read the guide and ignore the product entirely. Direct vendor comparisons live elsewhere, on the comparison page, where sources are cited and corrections are welcome.
How often is the Knowledge Centre updated?
Every article carries a published date and a last-updated date, and both are exposed in the page structured data and the XML sitemap so you can always see how current a guide is. We revise a guide when the underlying standard changes, when accepted guidance moves, or when something we describe in the platform changes. We would rather update an existing guide than leave two versions of the same advice in circulation.
Where should I start?
If the subject is new to you, read what is penetration testing, then continuous penetration testing for how the model has changed. If you are preparing for an audit or writing a scope, the standards guides are more useful: OWASP Top 10 and NIST SP 800-115. If you already have a specific problem, go to the best-practice guides on API security, Kubernetes security or common Active Directory issues.
How is a guide different from a solution page?
Guides teach; solutions pages describe what we sell. A guide such as attack path validation or EASM explained is useful whether or not you ever become a customer, and stays useful if you choose another provider. If you want the product view of the same idea, each guide links across to it.
Can I cite or share these guides?
Yes. Link to them, send them to colleagues, or reference them in internal standards, scoping documents and security awareness material, with attribution to PentestOps. Please link rather than republishing the full text, so readers always land on the current version rather than a snapshot.
Is any of this legal or compliance advice?
No. These guides are technical education. Frameworks such as PCI DSS v4.0, HIPAA and ISO 27001 are described so you can understand the testing evidence they expect, but how any of them applies to your organisation is a decision for your auditors, legal advisers and regulators. If you think we have got something wrong, tell us and we will correct the guide.
