About PenetrationTestingCost.com

An independent reference for the cost of penetration testing engagements. Operated by Digital Signet, founded by Oliver Wakefield-Smith. Built so the budgeting question for external network, web app, internal, mobile, cloud, red team, and CREST-aligned penetration tests can be answered without a sales call.

Why this site exists

Every pentest provider gates pricing behind a discovery call. Even the firms that publish day rates (Trustwave SpiderLabs, NCC Group, Rapid7) caveat them so heavily that buyers can't plan a budget without three sales calls and an NDA. Compliance frameworks (PCI DSS v4.0 Requirement 11.4, SOC 2 CC4.1 / CC7.1, ISO 27001 Annex A.12.6, HIPAA Security Rule, FedRAMP) all surface penetration testing as mandatory or strongly recommended without specifying cost ranges. The gap: buyers know they need a pentest but cannot anchor what one should cost.

This site closes that gap. Tier bands are wide enough to span freelancer ($800-$1,500/day) through boutique firm ($1,200-$2,500/day) through Big 4 ($2,000-$3,500/day) through PTaaS subscription ($20K-$50K/year), with engagement-level pricing by test type, company size, and compliance driver. No email gate. No discovery call. No affiliate parameter.

Who runs this

Operated by Digital Signet, an independent AI-development studio founded by Oliver Wakefield-Smith. Editorial direction is set by Oliver. Drafts are produced via Digital Signet's autonomous AI development methodology and reviewed against the editorial framework before publication. Digital Signet does not run a penetration testing practice, does not act as a CREST or NCSC CHECK assessor, does not sell pentest services, and does not accept paid placements from any pentest firm.

Sister cost-reference sites in the Digital Signet network span the adjacent security and compliance cost surfaces: iso27001cost.com, soc2compliancecost.com, pcicompliancecost.com, hipaacompliancecost.com, databreachcost.com, and gdprfine.com.

Editorial position

This is a reference, not a lead-gen funnel. The site does not collect email addresses to download a budget template, does not run a chatbot pretending to qualify visitors for a sales call, and does not have a quote-request form that routes to a partner firm. Outbound links to pentest providers are plain unaffiliated URLs. The site has no commercial relationship with any of the pentest firms or PTaaS platforms cited.

How we operate

Source pattern

Every cost band on this site reflects three input streams: (a) public pentest firm day-rate guidance and engagement-pricing pages from named providers (Trustwave SpiderLabs, Rapid7, Schellman, NCC Group, Cobalt, HackerOne, Bishop Fox, NetSPI, Coalfire, Secureworks), (b) standards-body guidance (OWASP WSTG v4.2, NIST SP 800-115, CREST OVS / CBEST, PCI DSS v4.0 Requirement 11.4), and (c) practitioner panels (IT Jobs Watch UK contractor day rates, r/cybersecurity practitioner write-ups, SANS Internet Storm Center). Where a band differs from a vendor's own marketing copy, the band reflects the practitioner side of the spread.

No paid placements

There are no sponsored slots, no pay-to-rank, no commercial relationships with any pentest firm or PTaaS platform. Provider tier ordering reflects published day-rate bands; PTaaS ordering reflects published per-engagement and per-subscription pricing. The site has no paid surface anywhere.

No affiliate parameters

Outbound links to vendor pricing pages and pentest firm sites are plain unaffiliated URLs. Cross-links to sister Digital Signet cost references (iso27001cost.com, soc2compliancecost.com, pcicompliancecost.com, hipaacompliancecost.com) are internal portfolio references, not affiliate links.

Monthly verification

Day-rate bands and engagement-cost figures are re-verified against public sources on the first business week of each month. The current verified label reads May 2026.

Single-source freshness

The verification date is held in one constant (LAST_VERIFIED_DATE) imported by every page. Footer text, Article schema dateModified, and visible page headings all read from that single source so date drift across pages is structurally impossible.

Conservative band math

Where the practitioner community and vendor marketing diverge, the site cites the wider band that includes both extremes. Headline figures ($5K-$100K+, average $18,300) reflect the full freelancer-to-Big-4 spread across all eight test types, not a single vendor's pitch.

Related cost references

Pentest cost decisions rarely live in isolation. The compliance framework you are testing against, the breach-cost gravity that justifies the budget, and the related certification costs all anchor the conversation. Sister sites in the Digital Signet network:

Digital Signet is not affiliated with CREST, the NCSC CHECK scheme, the PCI Security Standards Council, OWASP, NIST, or any of the named pentest firms or PTaaS platforms cited on this site.
