About iso27001certificationcost.com

Most top-ranking pages on the ISO 27001 cost question are owned by someone selling something: a certification body funnelling toward a quote, a GRC platform funnelling toward a demo, a consultancy funnelling toward an engagement. Useful information sits behind a form gate and the figures are positioned to support the sale.

The intent here is the opposite. Publish defensible cost ranges, show the assumption set, source the figures from public reference material, and let the reader make the decision. There is no email gate on the calculator. There is no chat widget. There is one contact form on the calculator page for scenarios that do not fit cleanly into the calculator, and one sentence about who runs the site.

This site is operated by Digital Signet, an independent AI-development studio founded by Oliver Wakefield-Smith. It is part of a portfolio of consumer cost-reference and calculator sites we run as a live R&D lab for our Signet methodology, an autonomous AI development team that ships real software at scale.

Digital Signet does not sell ISO 27001 certification, does not act as a certification body, does not run a GRC platform, and does not accept paid placements from any vendor in the compliance space. 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. Review depth scales with site tier.

For consulting enquiries (fractional CTO, AI product strategy, autonomous-dev-team setup): see digitalsignet.com.

Every site in the network operates under the same editorial principles. They are listed openly so they can be audited.

• Built on publicly-available reference material. UKAS-accredited certification body day-rate guidance, GRC vendor public pricing, published UK practitioner survey data, public consultant day-rate ranges. Sources are cited on the methodology page.
• Calculator math is documented inline. The full pseudocode, the assumption set, and the multipliers are published on the calculator page. The math can be re-derived without contacting us.
• No paid placements. No supplier sponsorships. Independent of certification bodies, GRC platforms, and consultancies. We do not rank GRC vendors based on payment. We do not accept fees to soften a recommendation.
• Update only when the underlying reality changes. No cosmetic date bumps. Triggers for revision are listed on the methodology page (standard revisions, accreditation framework changes, material day-rate movement).

Some figures cannot be sourced cleanly enough to publish. Listing them openly is part of the credibility surface.

• Specific certification-body fee tariffs. BSI, LRQA and others redact specific fee tariffs in writing. We publish the tier band, not the named-body specific quote.
• Named-firm consultant rate cards. Day rates are presented as bands. Named-firm rate cards are confidential.
• Side-by-side GRC feature grids. We publish positioning notes for major vendors but do not produce feature grids. Feature parity changes quarterly; static grids are stale within months.

For methodology questions, corrections, or scenarios where the calculator output does not produce a defensible budget figure: oliver@digitalsignet.com. There is no newsletter signup, no email gate on any tool, no chat widget.
