Why You Should Use Penetration Testing To Safeguard Your Business
The first step in safeguarding your business would be to review your existing setup and see where your business is today.
No matter how safe you think you may be, no business is immune from Cyber Attacks.
Often Cyber criminals will take advantage of software that has not been updated, companies that don’t have strict policies or schedule for updating both software and Operating System updates can be exploited.
Zero-day attacks can cause great harm, these are when hackers search for vulnerabilities and don’t rely on existing known attacks. Zero-day attacks are from hackers that access systems through previously unknown exploits.
Another Reason Business Should Stay Ahead With Pen Testing
Cyber attacks aren’t just reserved for large corporations—they target businesses of all kinds, often aiming to steal sensitive information, disrupt operations, or even hold data hostage. The cost of cyber crime is rising fast, predicted to hit an astronomical £10.66 trillion globally by 2028. Imagine the damage: loss of data, productivity, and potentially significant financial loss.
Hamilton Group’s Pen Testing Service
Hamilton Group uses state of the art pen testing services to ensure we can uncover the smallest weakness in your security. Our experts can simulate a safe attack just like hackers would in the wild (completely safe to do). We can then recommend or if you are working with Hamilton Group as your Outsourced IT Support provider, we can proactively fix the issues.
We test like the cybercriminals would and testing is performed on devices, servers, Websites, network infrastructure and your environment both internally and externally.
Hamilton Group can perform tests on a one off basis or we can continually monitor your network and ensure that you continue to be secure.
External infrastructure penetration test
External pen testing is just that external to your internal network. An attacker would attempt to gain remote access to your internal network by using exploits, these target security issues and vulnerabilities on your devices in the office. These can be Firewalls, Managed Switches or external Internet Services that control Line of Business Applications (LOB).
Hamilton Group will test all your Internet-facing devices. We include E-mail Servers, Domain name servers, Firewalls, Line of business applications.
Our goal is to identify issues that can breach your external network.
A report certified by CREST will be provided.
Internal infrastructure penetration test
A Hamilton Group internal pen test will discover what an attacker would likely achieve if they were given access to your network.
The reason is we want to check what vulnerabilities your network has, because if an attacker has already gained access to an external firewall, we need to see what damage they could do.
Not only actions taken by an outside attacker but we want to check for what could be done via a phishing attack or even a rogue employee that wanted to either damage the system or steal company data.
Our work will emulate the actions that could be taken, identify the risks and then provide the data to be able to protect your business.

Some Companies We’ve Worked With






Let’s work together
Benefits of our cybersecurity solutions
For us, cyber security isn’t just about software and protocols. It’s also about equipping people with the right knowledge and tools. That’s why we offer Security Awareness Training across the UK, helping you and your team stay vigilant. Most of our training is delivered in Yorkshire, where we work closely with local businesses to help them understand threats and make smarter security decisions.
Imagine a small business we worked with that had no prior experience with cyber security. After just a few sessions, their team was better equipped to spot phishing attempts, prevent data leaks, and keep their systems secure—saving them from potential breaches that could have cost them dearly.

“Our email wasn’t performing very well so we asked Hamilton Group to take a look & Carl proposed to migrate us to MS Exchange.
Carl was very helpful throughout & the migration went very well.
He was on hand to sort out any teething issues, taking calls early morning & into the night, to ensure we were up & running smoothly.
Would recommend for knowledge, attention to detail & great customer service.”
