Why Penetration Testing Matters

You’ve invested in secure, well-managed IT systems with Core Team One. So why would you need Penetration Testing? The answer is simple: cyber threats evolve every day, and even the best configurations can’t guarantee immunity from new vulnerabilities.

What is Penetration Testing?
Penetration Testing (or “pen testing”) is a controlled, ethical attempt to break into your network—just like a hacker would. It simulates real-world attacks to uncover weaknesses before cybercriminals do. Think of it as a proactive health check for your IT security.


Internal vs External Penetration Testing

  • External Pen Test: Focuses on your public-facing systems—websites, firewalls, and services exposed to the internet. It answers the question: Can an attacker get in from the outside?
  • Internal Pen Test: Simulates an attacker who already has access to your internal network, whether through a compromised device or malicious insider. It checks how far they could go and what data they could access.

Why Internal Tests Are Critical

Even with CTO managing your core systems, internal tests often uncover vulnerabilities in areas outside our deployment scope—such as third-party apps, CCTV systems, printers, or phone systems. In today’s IoT-driven world, these devices can become weak links in your security chain. A comprehensive test ensures every connected device is assessed, not just your servers and PCs.


Independent Testing – No “Fox Watching the Hen House”

We believe security should be impartial. That’s why CTO partners with a CREST-certified external provider for all penetration testing and reporting. We facilitate the process, but the testing and results come from an independent expert—giving you confidence in the integrity of the findings.


Remediation Support

If vulnerabilities are found in systems we’ve deployed, CTO will remediate them as part of our service. For issues in third-party systems—such as IoT devices or vendor-managed platforms—we can’t directly fix them, but we’ll help you manage the remediation process with those vendors. This support is available on a chargeable basis if you need us to coordinate and oversee the fixes.


Pen Testing as a Service (PTaaS)

Security isn’t a one-time job. New threats appear constantly, and compliance requirements often demand regular testing. With Pen Testing as a Service, CTO can arrange periodic tests—monthly, quarterly, or annually—to ensure your network remains secure and any new vulnerabilities are identified before attackers exploit them.
