Penetration testing

Penetration testing

Proof of what’s exploitable — not a list of what might be.

A vulnerability scan tells you where you could be exposed. A penetration test proves how far someone could actually get.

Real exploitation

We prove which weaknesses can actually be exploited, not just list what might be.

Business-impact focus

Findings framed by what an attacker could actually reach — data, systems, domain admin.

Manual-led testing

Skilled testers chain issues together the way real attackers do — beyond any scanner.

Safe & controlled

Testing runs to an agreed scope and rules of engagement, without disrupting production.

Prioritized remediation

Every finding comes with reproduction steps and a fix, ranked by real-world risk.

The short version

What is penetration testing?

A penetration test is an authorized, simulated attack on your systems, carried out by security professionals who actively attempt to exploit weaknesses — the way a real attacker would — to demonstrate genuine business impact. Unlike a vulnerability assessment, which identifies and lists weaknesses, a penetration test proves which ones can actually be exploited, and how far an attacker could get once inside.

Engagements are scoped by how much your testers know going in:

Black box

No prior knowledge — testers start from the outside, exactly like an external attacker.

Grey box

Limited access or credentials — simulating a user, partner or a breached low-level account.

White box

Full visibility into architecture and code — the most thorough coverage in the time available.

Why manual-led matters

A scan lists possibilities. A pentest proves reality.

Automated tools are a starting point — but they can’t think like an attacker or chain issues into the path that actually matters.

Frequently Asked Questions

Everything You Need to Know

From a single website scan to a full enterprise-wide assessment, PS INFOSEC covers every layer of your security posture — technical testing, cloud, compliance, and everything in between.

A vulnerability assessment identifies and lists known weaknesses through scanning and CVSS scoring. A penetration test goes further — actively exploiting those weaknesses and chaining them into attack paths to prove real-world business impact. Many teams run frequent VAs and periodic penetration tests together.

It depends on your goal. Black box simulates an external attacker with no knowledge; grey box simulates a user, partner or breached account with limited access; white box gives full visibility for the most thorough coverage. We help you pick the right fit during scoping.

Testing runs to an agreed scope and rules of engagement, scheduled to minimise impact. Higher-risk activity can be run against staging or within controlled windows, so business operations aren’t disrupted.

Commonly once a year, and after any major change — a new application, a significant infrastructure change, or ahead of a big release or compliance audit. High-risk environments often test more frequently.

Yes — safely, and within the agreed scope. That’s what separates a penetration test from a scan: we demonstrate genuine impact by exploiting weaknesses, without causing damage or exposing sensitive data.

Yes — a retest to confirm remediated vulnerabilities are genuinely resolved is included, so you have proof the fixes hold.
