How does a penetration testing company work?
The penetration testing process is designed to find vulnerabilities in your system before an attacker does. It simulates real-world attacks so you can identify and fix weaknesses before they’re exploited.
When you hire a penetration testing company in the UK, they follow a mostly similar methodology to detect vulnerabilities in your systems.
They apply a combination of automated scans and manual probing to find and exploit vulnerabilities to help you understand the risk associated with each vulnerability.
Penetration testing methodology
Reconnaissance: The first stage of the attack where the pentester gathers information about the target system.
Scanning: The second stage is where the pentester uses automated tools to identify potential vulnerabilities.
Gaining Access: The third stage is where the pentester tries to exploit the vulnerabilities they’ve found to gain access to the system.
Maintaining Access: The fourth stage is where the pentester attempts to maintain their access and create a backdoor for future access.
Covering Tracks: The final stage is where the pentester attempts to clean up their tracks and cover their tracks so as not to be detected.

What makes penetration testing important for your business?
There are many reasons why penetration testing is important for your business. Here are some of the most common ones:
Security posture management:
Penetration testing can help you understand your security posture and identify areas for improvement.
By identifying and prioritizing vulnerabilities, penetration testing can help you manage risk more effectively.
Many regulations and standards require penetration testing as part of your compliance program.
In the event of a breach, demonstrating that you’ve taken steps to secure your systems can help limit damage to your reputation.

Why is it important to choose the right penetration testing company in the UK?
Security audits and penetration testing are naturally feared by organizations often more than the cyber attacks these are designed to stop.
There are many reasons behind this.
A pentest process can be long, tiring, and expensive. It often involves human hours put in by the employees of the target company. That cannot be good news for business. Moreover, the mail trail that follows the pentest is often long enough to confuse the developers trying to fix the issues.
Pentest customers are often thrown into further darkness after the pentest.
With the right penetration testing service, you can go through the pentest process without facing any of the issues. The right penetration testing company will be attentive to your specific needs, provide you with a solution that is easy to use and navigate and help you with the interpretation of the report and execution of the fixes.

5 things to look for in a penetration testing company
When looking for a penetration testing company in the UK, here are some of the things you should look for:
A good pentest company will offer a self-served tool that is super easy to navigate and minimizes the effort required from the users.
Manual pentest capabilities
The company should also have manual pentest capabilities to supplement the automated scans. The manual scans are not supposed to replace the automated scanners but to augment their capabilities and validate the results.
The report should be actionable and easy to understand. It should also include remediation steps. Some UK penetration testing companies go ahead and include video PoCs to reproduce the vulnerabilities to make the task easier for developers.
Thorough remediation support
When we say thorough remediation support, we mean easily navigable guidelines, video PoCs, and in-chat or in-call assistance from security experts.
Publicly verifiable certificate:
Once you have fixed all the vulnerabilities indicated by the pentest company and produced evidence for the same in the re-scans, the pentest companies should give you a publicly verifiable certificate that declares you secure at that point in time. Please note that this is not equivalent to a compliance certificate.
