Firewalls and antivirus software are what most businesses use to stay safe, but how do you know those defences will hold up against a determined human attacker in a world where threats change every day? That question is best answered by penetration testing.
Penetration tests evaluate your security by simulating a real-world attack, which helps you see where the real risk is. Microbyte offers thorough penetration testing services to small and medium-sized businesses (SMEs) in the UK and around the world. We will help you meet regulatory requirements and sleep better knowing your systems are safe.
Penetration testing is a manual, authorised simulation of a cyberattack against your computer systems. Unlike a criminal, our certified ethical hackers work with your permission to evaluate your security. The goal is to identify exploitable logic flaws and misconfigurations that automated tools simply cannot find. We don’t just tell you there is a vulnerability; we attempt to exploit it. You will see the potential business impact of an attack without the fallout, and know if a hacker could access your financial data or take administrative control.
A lot of business owners think they are paying for a penetration test when they are really getting a vulnerability scan, and it’s important to know the difference.
For a deeper look at why this matters for your budget and security, read our guide on the difference between vulnerability scanning and penetration testing.
We understand that navigating compliance frameworks and insurance forms is stressful. However, these regulations are increasingly mandating manual testing:
Many SMEs only discover these security gaps during an audit or after an incident, but penetration testing allows you to identify them on your own terms.

We will look at your business from the outside, like a hacker would. Our testers will try to get past your web servers, VPN gateways, and perimeter firewalls. We will look for services that are open or encryption that isn't strong enough to keep an attacker out of the public internet.

What happens if an attacker gets past your firewall, or an employee’s laptop is compromised? We will run this test assuming the threat is already inside to validate your internal vulnerability testing and network segmentation. We will connect to your internal network to see if we can move between systems or escalate our privileges to access your sensitive data.

If you use custom-built websites or client portals, you need to check them very carefully. Our testers will look at the logic of your application and compare it to the OWASP Top 10. We will look for serious problems like SQL Injection or Broken Authentication that could put your users' data at risk.

Moving to the cloud doesn't mean Microsoft handles everything. Under the Shared Responsibility Model, they secure the physical datacentre, but you must secure the configuration. Our testing will review your specific tenant settings in Azure or M365 and check for insecure Identity and Access Management (IAM) roles and weak MFA policies.
We know engaging a security team can feel daunting, but you can rest assured that we follow a structured four-phase lifecycle to ensure the process is clear and safe for your business.
We take the safety of your systems seriously, so our professional penetration testing follows a strict framework.
Most vendors will provide you with a PDF report and walk away, leaving you with a list of problems to solve. That isn’t our style.
The price depends on how large and complicated your environment is, so the number of IP addresses and how complicated your apps are are two things to think about. Qualified UK testers usually charge between £800 and £1,200 per day, so be careful of any quotes that are much lower than this; they are often just automated scans that look like real quotes. Proper manual testing takes time and skilled workers, but it gives you results you can trust.
Penetration testing is the only way to confirm whether your controls prevent unauthorised access under real attack conditions. It moves your security from “hope” to “assurance.” Microbyte provides the technical capability to not only find these vulnerabilities but to fix them, ensuring your business remains compliant and secure.
Don’t wait for a breach to test your defences. Speak to Microbyte today to scope a penetration test that fits your infrastructure and compliance requirements.
