Find Your Weak Spots Before Hackers Do
Cyber criminals don’t discriminate, they’ll exploit any gap they find, from outdated software and unpatched systems to weak passwords and unsuspecting employees clicking suspicious links.
That’s why vulnerability assessments and penetration testing services are so important. Vulnerability assessments scan for security weaknesses, while pen testing simulates genuine attacks to reveal what’s actually exploitable. Hamilton Group delivers both services with actionable steps to fix your defences and keep up with emerging cyber threats.

If any of these ring true, you should consider a vulnerability assessment and penetration testing as your next step.
- Unsure whether your firewalls, servers, or apps are properly secured?
- Handling sensitive client or financial data that must stay compliant?
- Concerned about insider threats or phishing attacks?
- Worried about losing business if a breach damages your reputation?
- Never tested your network or web apps against modern attack methods?
- Relying on outdated or unpatched systems that could be exploited?
Our Penetration Testing Services
Our accredited pen testing and vulnerability assessment services cover your entire IT environment. Our experts work like hackers (but on your side) to expose risks and secure your systems.
External Infrastructure Testing
Simulates an outside attack on your internet-facing systems, such as firewalls, servers, and applications. We highlight potential entry points and provide a CREST-certified report to strengthen your perimeter security.
Internal Infrastructure Testing
Replicates what an attacker, or even a rogue employee could do once inside your network. We identify weaknesses in access controls, patching, and configurations to minimise internal risks.
Web Application Assessments
Tests your websites, portals, and apps for vulnerabilities such as injection flaws, broken authentication, or data exposure. Essential for businesses running customer-facing platforms.
Continuous Monitoring Options
Go beyond one-off testing. With ongoing vulnerability assessments, Hamilton Group provides continuous visibility of new risks as they emerge, ensuring your defences stay up to date.

Frequently Asked Questions
Penetration testing is a form of security testing where ethical hackers simulate real-world cyber-attacks to identify vulnerabilities before actual hackers can exploit them. Hamilton Group’s penetration testing services provide a clear, actionable report showing how attackers could gain access to your critical assets, along with practical steps for fixing security weaknesses.
A vulnerability assessment focuses on vulnerability identification using tools such as automated scans to highlight security flaws and prioritise risks. Penetration testing goes further by exploiting vulnerabilities in a safe, controlled way to understand the potential business impact. The two services are complementary, vulnerability assessments help with ongoing monitoring, while pen testing provides deeper assurance. Hamilton Group can provide a combination of both.
Penetration testing services combine vulnerability scanning, vulnerability analysis, and manual techniques. Ethical hackers simulate how attackers might target your information security systems, attempting to exploit weaknesses in your network, web applications, or internal systems. Pen testing with Hamilton Group includes reconnaissance, exploiting vulnerabilities, and documenting findings in a detailed security testing report tailored to your business.
Following the test, you receive a comprehensive report highlighting identified vulnerabilities, potential security flaws, and their severity. We then provide clear remediation guidance so you can address risks effectively. If you’re a managed client, Hamilton Group can work directly on fixing the issues, ensuring your systems are secured and your critical assets remain protected.
Most businesses benefit from penetration testing at least once a year, but regulated industries or those handling sensitive data may require more frequent security testing. Hamilton Group also recommends it’s vital to re-test after major system changes, software upgrades, or new deployments to ensure no new vulnerabilities have been introduced.
The cost depends on the scope, size, and complexity of your environment. Factors include the number of systems, type of testing (external, internal, or web app), and level of detail required. Hamilton Group provides transparent quotes for our CREST-accredited penetration testing services, ensuring you know exactly what’s covered and why.
