Protecting Local Government with Expert Penetration Testing
“We needed to find a way to meet very tight budget constraints. Of the suppliers we spoke to, only CyberLab demonstrated what we felt was a genuine desire to engage with us to reach a workable solution for both parties. I’d recommend CyberLab not just for their expertise in the whole cyber security area, but for their personalised and professional approach.”
– Mark Smith, Server Support Manager, Nottingham City Council

Benefits of Penetration Testing for ISO 27001 Certification
Identify Vulnerabilities in Your ISMS
Penetration testing uncovers potential weaknesses in your Information Security Management System (ISMS), helping you secure your environment against cyber threats and ensuring your systems align with ISO 27001 requirements.
Ensure Data Protection and Confidentiality
ISO 27001 focuses heavily on safeguarding sensitive data. Regular penetration testing ensures that your data protection measures are robust, protecting against data breaches and ensuring confidentiality.
Prove Security Controls & Reduce Risk
Penetration testing verifies the effectiveness of your security controls, proving your ability to meet ISO 27001’s risk management criteria and mitigating potential risks before they become threats.
Ongoing Compliance and Improvement
ISO 27001 requires continuous improvement of security practices. Regular penetration testing helps maintain compliance by proactively identifying vulnerabilities and ensuring your ISMS evolves with emerging threats.
