To protect platform integrity, every review on our platform—verified or not—is screened by our 24/7 automated software.

Written by the company

Plainsight Security Ltd is an independent UK cybersecurity company providing practical, professional security services to businesses of all sizes. We help organisations understand their cyber security risks, identify vulnerabilities and take meaningful steps to improve their security and resilience. Our services include Cyber Essentials, Cyber Essentials Plus, penetration testing and a range of cyber security assessments designed to give businesses a clearer understanding of their security position. We provide testing of websites, web applications, networks, infrastructure and other systems, helping organisations identify weaknesses before they can be discovered and exploited by criminals. We believe cyber security should be understandable, proportionate and relevant to the organisation involved. Rather than simply producing technical reports, we aim to help our clients understand what the findings mean for their business and what they can do about them. Our approach combines technical expertise with clear communication, allowing both technical and non-technical stakeholders to understand the risks and priorities. As a UK business, we take pride in providing a personal and responsive service. We work with organisations directly and also support IT companies and managed service providers through partnership arrangements, helping them provide additional cyber security services to their customers. Our penetration testing services are carried out using recognised industry methodologies and professional security testing practices. We look beyond simply identifying vulnerabilities, considering how weaknesses could potentially be combined or exploited in a real-world attack. For organisations working towards Cyber Essentials or Cyber Essentials Plus, we can also provide guidance and support to help them understand the requirements and prepare effectively. At Plainsight Security, our goal is simple: to help businesses find their security weaknesses before an attacker does. We believe good cyber security is not about creating unnecessary fear or complexity. It is about understanding the risks, addressing the important issues and giving businesses confidence that appropriate measures are in place. Whether you need Cyber Essentials certification, Cyber Essentials Plus, penetration testing or a broader assessment of your cyber security, Plainsight Security provides a professional, independent and straightforward service focused on helping businesses become more secure.

Excellent service and expert advice

Excellent service and expert advice

Plain Sight Security carried out security checks on two of our websites and provided clear, practical advice on the adjustments needed to protect them. Mark also gave us lots of helpful guidance on what we should and shouldn’t do to keep our online presence secure going forward.

The service was absolutely excellent. Mark couldn’t have been more helpful and took the time to guide us through everything clearly. I would highly recommend Plain Sight Security, and we will certainly be using them again.
