Frequently asked questions
Most companies test twice yearly, though smaller Bristol businesses should conduct at least one annual penetration test. Industry compliance standards like PCI DSS mandate annual testing as a minimum requirement. Though larger enterprises often test quarterly and after new releases for enhanced security.
A complete penetration test typically takes 4-6 weeks from planning to final delivery. The actual testing phase usually runs 1-2 weeks, depending on your environment's size and complexity. Planning and reporting add extra time.
Choose a penetration test provider in Bristol by evaluating their industry experience, certifications, tailored testing approach, and thorough reporting. Ensure they follow recognized standards like OWASP and NIST and offer ongoing remediation support.
Healthcare organizations under HIPAA, financial services with PCI DSS requirements, and service organizations needing SOC 2 compliance benefit most. Bristol’s thriving tech, aerospace, and manufacturing sectors also require regular testing for intellectual property protection.
