Vulnerability Assessment
You can’t patch what you don’t know about. A vulnerability assessment gives you a complete, prioritised inventory of every known weakness across your infrastructure — so your team can fix what matters most, first.
What is Vulnerability Assessment?
A systematic, comprehensive scan and manual review of your IT infrastructure to identify, classify, and prioritise security vulnerabilities — giving you a clear, actionable risk register.
The gap between your assumed security posture and your actual posture grows every time new software is deployed or a configuration changes. Without regular assessment, unpatched vulnerabilities accumulate — and attackers actively scan for exactly these gaps.

What We Test
How We Run This Engagement
Every engagement follows a defined, transparent process — no surprises, no hidden scope changes, and no invoice for work you did not agree to.
Scoping
Define IP ranges, systems, and environments to be assessed.
Automated Scanning
Run industry-standard vulnerability scanners across all in-scope systems.
Manual Validation
Manually review scanner output to eliminate false positives and confirm real findings.
Risk Classification
Classify all findings by CVSS score, exploitability, and business impact.
Reporting
Deliver a clear vulnerability register with prioritised remediation guidance.
Retest
Verify critical and high vulnerabilities have been resolved.
Why Work With Vigilant Defenders
Manual Testing. Not Scanner Output.
Automated tools find known signatures. Our certified consultants find the chained attack paths, logic flaws, and context-specific vulnerabilities that no scanner will surface. Every finding we report is manually verified — zero false positives.
Reports Built for Action, Not Filing.
Every finding includes a proof-of-concept, a CVSS risk score, the affected system or endpoint, and step-by-step remediation guidance written for the team that has to fix it. Your developers and your board both get a report they can use.
Confidentiality From Day One.
We sign a formal NDA before any technical discussion begins. Your vulnerabilities, your architecture, and your engagement findings are treated with the same confidentiality as attorney-client communications. We have never disclosed client information.
We Stay Until It's Fixed.
Every engagement includes a complimentary retest once your team has addressed the findings. We verify that the vulnerabilities are genuinely closed — not surface-patched — and issue a formal retest certificate you can share with clients and auditors.
Manual Validation. Zero False Positives.
Every vulnerability scanner produces false positives. Our consultants manually review every finding before it goes in your report — confirming it is real, understanding its actual exploitability in your environment, and removing the noise that wastes your IT team’s time. You receive findings you can act on immediately.
Frequently asked questions
Everything you need to know about this engagement.
A vulnerability assessment identifies and prioritises weaknesses but does not actively exploit them. Penetration testing goes further — an expert attempts to exploit vulnerabilities to demonstrate real-world impact. For organisations new to security testing, a vulnerability assessment is often a good starting point.
