Nine providers, sourced

Of 9 providers checked today, only Precursor Security publishes a live UK day rate (£1,250/day CREST). Every other UK or US Tier 1 provider is quote-only or aggregates pricing into PtaaS tiers without numbers. The market is structurally opaque — surfacing this honestly is the methodology rule's intent.

Remediation reality — what happens after the report lands

Pen test pricing always assumes the findings get fixed. Cobalt's 2025 platform telemetry says they often don't. Plan remediation effort and budget separately.

Testing standards

What each standard means for your budget

Six standards routinely cited in UK + US pen test procurement. CHECK and Cyber Essentials Plus are UK government schemes. CREST is the de facto UK commercial baseline. NIST 800-115 is the US federal reference. OWASP is global methodology.

CREST · uk

CREST

Voluntary — but the de facto standard for UK commercial pen test procurement
Days: Neutral — CREST methodology aligns with industry standard day counts
Rate: CREST consultant day rate is the UK benchmark (£1,000-£1,500/day for standard, £1,200 median)
NCSC (UK National Cyber Security Centre) · uk

CHECK

Mandatory for UK government and CNI (Critical National Infrastructure) pen testing
Days: Neutral — same day counts as standard CREST
Rate: CHECK Team Member-led work typically carries a £300-£500/day premium over standard CREST
NCSC (UK) · uk

Cyber Essentials Plus

Required for UK government supplier contracts handling sensitive data
Days: Typically 1-3 days for small organisations, 3-5 for medium, depending on infra footprint
Rate: Often delivered as a fixed-price assessment (£1,500-£4,000 for small orgs) rather than day-rated
OWASP Foundation · global

OWASP Testing Standards

Voluntary — industry standard for web/mobile/API testing methodology
Days: OWASP-aligned testing is the baseline — most engagement quotes implicitly follow OWASP coverage
Rate: Neutral — does not affect day rate
NIST (US) · us

NIST SP 800-115

Voluntary — common reference for US infrastructure and network pen testing methodology
Days: Neutral — provides methodology, not duration
Rate: Neutral
PCI Security Standards Council · global

PCI DSS 4.0 testing

Mandatory for organisations handling payment card data (PCI DSS 11.4)
Days: Adds 30-50% to day count for full CDE scope vs equivalent non-PCI test
Rate: Specialist QSA-aligned testers typically at upper end of day-rate band
Seven scopes

Why this exists

The pen test market is structurally quote-only

Of nine pen test providers checked today — Cobalt, HackerOne, Bishop Fox, Synack, NCC Group, JUMPSEC, Pentest People, Bulletproof, Precursor Security — only Precursor publishes a live day rate. PtaaS platforms advertise tier names but no numbers. Every other Tier 1 vendor is engagement-quoted.

That makes pen test procurement hard. The two existing independent references (penetrationtestingcost.com and pentestingcost.com) cite numbers without methodology. The vendor "cost guides" sell their own services. The aggregator content propagates figures that can't be traced to a vendor source — the "$4,000-$7,000/day Bishop Fox" figure being a frequent example we deliberately exclude.

This site does three things differently: surfaces the quote-only reality honestly, triangulates UK day rates from at least four independent sources before publishing a range, and re-verifies every figure quarterly with the pre-deploy gate enforcing the verification dates. Methodology.

Market consolidation · 2025-26

WorkNest acquired Pentest People + Bulletproof in 2025

Two of the UK's mid-market CREST-certified pen test providers — Pentest People and Bulletproof — are now both under the WorkNest group. Both original domains 301-redirect to worknest.com. If your procurement shortlist treats them as independent options for diversification, they're now the same parent.

Procurement implication: if you're tendering for diversification or supplier-redundancy reasons, treat Pentest People and Bulletproof as a single supplier. WorkNest also owns several UK HR and employment law brands, which is a different shareholder profile to a pure-play security firm.
