This document provides 5 useful, short, to the point concise tips for anyone looking to purchase a pen test or procure penetration testing quotes in the UK. Penetration Testing Certifications When approaching companies for penetration testing quotes, two certifications stand out the OSCP (Offensive Security Certified Professional) and the CREST Certified Tester (CCT) which has two options CREST Certified Web Application Tester (CCT ACE) and the CREST Certified Infrastructure Tester (CCT ICE). CREST CCT Certification Overview The CREST CCT requires passing a multiple choice + long form (essay style) questions and a final practical exam where a penetration tester is assessed against practical challenges designed to push senior level penetration testing consultants to their limits. OSCP Certification Overview The OSCP certification takes a slightly different approach as the course is online, with access to a large multi subnet training lab to help prepare you for the final 24 hour long exam, where a penetration tester has to perform a capture the flag style examination. After the 24 hour exam completes, a candidate has an additional 24 hours to submit a full severity ordered report.

PCI DSS 3.2, section 11.3 specifies a requirement to implement a penetration testing methodology that includes the following: Is based on industry-accepted penetration testing approaches (for example, NIST SP800–115) Includes coverage for the entire Cardholder Data Environment (CDE) perimeter and critical systems Includes testing from both inside and outside the network Includes testing to validate any segmentation and scope-reduction controls Defines application-layer penetration tests to include, at a minimum, the vulnerabilities listed in Requirement 6.5 Defines network-layer penetration tests to include components that support network functions as well as operating systems Includes review and consideration of threats and vulnerabilities experienced in the last 12 months Specifies retention of penetration testing results and remediation activities results For more information see Aptive’s page on , which explains in detail the requirements for a PCI DSS 3.2+ penetration test.
