Not every security need fits neatly into a standard penetration test. Core Sentinel Professional Services gives you senior, offensive-security expertise shaped around your actual requirements — whether that’s a specialised assessment, an advisory engagement, or experienced hands working alongside your team. The same senior, certified people who run our penetration tests, available on the terms that suit you.

Senior expertise, beyond the standard test
Our core penetration testing services cover the work most organisations need. But security rarely stops there. You might need a red team exercise that tests detection and response, a second opinion on an architecture decision, a source-code review, help preparing for a compliance audit, or simply an experienced offensive-security specialist embedded with your team for a project. Professional Services exists for exactly these situations — the engagements that don’t come in a box.
What never changes is the calibre of who does the work. Every engagement is led by a senior, OSCE- and OSCP-certified tester with decades of hands-on experience. No junior bench. No hand-off after the sales meeting.
How we can help
- Red team engagements — goal-oriented, real-world attack simulations that test not just your technology, but your detection and response. How far could a determined attacker actually get?
- Purple team exercises — working collaboratively with your defenders to sharpen detection and response in real time, turning offensive findings directly into defensive improvements.
- Security advisory & consulting — pragmatic, senior guidance on architecture, threat modelling, security strategy and where to focus limited resources.
- Source code review — manual review of your application’s source to find the flaws that black-box testing alone can miss.
- Social engineering assessments — phishing and human-focused testing that measures your real-world exposure, integrated with technical attack scenarios where it adds value.
- Compliance & audit support — testing and evidence aligned to SOC 2, ISO 27001, PCI DSS, APRA CPS 234 and similar frameworks.
- Remediation & retest support — hands-on help interpreting findings, prioritising fixes, and confirming risk is genuinely closed.
- Specialist & bespoke engagements — if your requirement doesn’t fit a template, that’s exactly what this service is for.
Engage us the way that suits you
Different organisations need security expertise in different shapes. Some want a single, well-defined project. Others want an ongoing relationship that flexes with their release cycles and compliance calendar. And some simply want experienced offensive-security capability available when they need it, without the overhead of a permanent hire.

We’re genuinely flexible on engagement structure. Whether you need a fixed-scope project, a recurring program, or senior expertise available on a more open, day-by-day basis — effectively an extension of your own team — we’ll shape the arrangement around what actually works for you. If you have a need that doesn’t fit the usual mould, that’s a conversation we welcome, not an exception we resist.
Why senior-led matters even more here
For advisory, red teaming and bespoke work, experience isn’t just helpful — it’s the entire value. Strategic guidance is only as good as the person giving it; a red team is only as convincing as the adversary it simulates. This is work that genuinely cannot be handed to a junior. With Core Sentinel, the senior specialist you talk to is the senior specialist who does the work.
Who we work with
We provide professional services to organisations across banking, finance, government, defence, health and education — from one-off specialist engagements to ongoing, embedded support. Whatever the shape of the need, we tailor it to your environment and your goals.
