Frequently Asked
Eight questions our scoping calls answer first.
Which penetration testing service do I need?
Most engagements combine 2-4 service types. For compliance: VAPT + Cyber Essentials Plus. For SaaS launch: Web App + API + Cloud (AWS/Azure/GCP). For FCA-regulated: Red Team + Threat Intelligence. Our 30-minute scoping call identifies the optimal service mix.
How much do penetration testing services cost in the UK?
Day rate for CREST-certified testers: £1,000-£1,500. Typical engagement ranges: small (single web app / external) £4,000-£8,000; mid-market combined £8,000-£18,000; enterprise (full-stack + cloud + red team) £18,000-£75,000+. All quotes are fixed-price after scoping.
How long does a penetration test take?
Single-target engagements 3-5 working days. Mid-market combined 7-10 days. Enterprise 12-15+ days. Red team 2-6 weeks. Cloud security review 4-15 days. Test duration is determined during scoping based on scope complexity.
Are all 21 services CREST-accredited?
Yes. Our CREST membership covers all penetration testing services. We are also IASME-accredited for Cyber Essentials Plus certification. Some specialty services (smart contract audit, AI/LLM pen testing) draw on adjacent CREST CRT/CCT credentials of our team members.
Can you bundle multiple services into one engagement?
Yes — bundled engagements typically save 15-25% versus separate contracts. Common bundles: VAPT + Cyber Essentials Plus, Web + API + Cloud, Red Team + Threat Intelligence + Purple Team. We design the bundle during scoping to match your scope and budget.
Will reports satisfy our auditor?
Yes. Reports are pre-mapped to FCA, NCSC, PCI DSS, ISO 27001, SOC 2, NHS DSPT, Cyber Essentials Plus, and cyber-insurance underwriting requirements. Audit teams submit directly without translation work.
How quickly can you start?
Standard engagements within 24-48 hours of contract signature. London on-site engagements within next business day. Emergency engagements (incident-driven, M&A urgency, regulator demand) within 4 hours via priority pipeline.
Do you sign NDAs?
Yes. Standard NDA before any technical detail is shared. We operate under a project-specific master agreement that includes data handling, deliverable IP, and breach notification clauses. Custom MSAs and AUP terms are accepted for enterprise and public-sector clients.
