The short answer
PCI security standards are the payment card security standards of the PCI Security Standards Council (PCI SSC), founded in 2006 by American Express, Discover, JCB International, Mastercard and Visa. PCI DSS is the best known of 17 listed in October 2026; others cover PINs, card production, devices, software and 3-D Secure. Card brands and acquirers enforce them.

PCI security standards are the security requirements for payment card data, devices and processes published by the PCI Security Standards Council (PCI SSC, sometimes called the PCI DSS council). The Council was founded in 2006 by American Express, Discover, JCB International, Mastercard and Visa. It maintains the PCI Data Security Standard (PCI DSS) that most businesses meet, plus specialist standards for PIN processing, card manufacturing, payment terminals, encryption and software. It writes the standards and qualifies the assessors who check them. It does not enforce them: the card brands and acquirers decide who must comply and what happens if they do not.
This page maps the whole family. If you only need to know what PCI DSS asks of your business, start with our guide to what is PCI DSS.
What is the PCI SSC?
The PCI SSC is a global standards body set up by the payment card brands to manage one set of security requirements instead of a separate programme for each brand. The Council says plainly that it does not monitor how its standards are implemented; whether an organisation must comply, and how it proves it, is decided by the brands and acquirers that run compliance programmes.
| Part of the Council | Role |
|---|---|
| Founding members (American Express, Discover, JCB International, Mastercard, Visa) | Sit on the Executive Committee, which sets the Council’s policy |
| Strategic members (UnionPay at the time of writing) | Can also serve on the Executive Committee |
| Board of Advisors | Elected by Participating Organisations; gives input and feedback on the standards |
| Participating Organisations | Merchants, banks, processors and vendors that join the Council, comment on draft standards and elect the Board of Advisors |
| Leadership team | Runs the Council day to day and reports to the Executive Committee |
The Council’s work falls into four areas: publishing and updating the standards, training and qualifying assessors, keeping public listings of approved assessors, devices, solutions and software, and publishing guidance such as FAQs and information supplements.
Who created PCI DSS?
The card brands did. Before PCI DSS, each brand ran its own security programme, so a merchant could face several overlapping sets of rules. The brands aligned them into PCI DSS version 1.0, published in December 2004, and created the PCI SSC in 2006 to own and develop the standard.
The current version is PCI DSS v4.0.1, published in June 2024 and the only active version. The future-dated requirements first introduced in v4.0 became mandatory on 31 March 2025, so every assessment now covers them.
The brands still set the rules around the standard: which merchants and service providers must validate, the levels that decide between a Report on Compliance (ROC) from a Qualified Security Assessor and a Self-Assessment Questionnaire (SAQ), and any penalties. Your acquirer passes those rules on through your merchant agreement. To see which SAQ your own set-up points to, try our free PCI compliance check.
How many PCI security standards are there?
When we checked in October 2026, the PCI SSC standards page listed 17 standards. That count includes the retired Payment Application Data Security Standard (PA-DSS) and three standards in a formal sunset period from 1 May to 31 October 2026, after which PCI SSC accepts no new submissions for them, although existing listings stay valid until their expiry dates: Software-based PIN Entry on COTS (SPoC), Contactless Payments on COTS (CPoC) and the 3DS SDK standard. The table covers the standards in active use.
| Standard | What it protects | Who it is for | How it is validated |
|---|---|---|---|
| PCI DSS | Account data wherever it is stored, processed or transmitted | Merchants, service providers and anyone who can affect the security of card data | ROC by a QSA, or an SAQ, each with an Attestation of Compliance (AOC) |
| PIN Security Requirements | PINs and the cryptographic keys that protect them at ATMs and point-of-sale terminals | Acquirers, processors and key injection facilities | PCI PIN security assessment by a Qualified PIN Assessor |
| Card Production and Provisioning (Logical and Physical) | Cards, card data and keys during manufacture, personalisation and provisioning | Card manufacturers, personalisers and provisioning services | Card production security assessment by a Card Production Security Assessor |
| Key Management and Operations (KMO) | Cryptographic keys used for PIN and P2PE data, including HSM-as-a-service | Organisations that manage those keys | KMO Assessor; listings were marked “coming soon” in October 2026 |
| Point-to-Point Encryption (P2PE) | Card data from the terminal to the decryption environment | P2PE solution, component and application providers | P2PE Assessor (a P2PE Application Assessor for applications), then a PCI SSC listing (see how P2PE works and our P2PE assessments) |
| 3DS Core Security Standard | Environments that perform 3-D Secure functions for online authentication | Operators of 3DS servers, directory servers and access control servers | 3DS Assessor (see PCI 3DS explained and our PCI 3DS assessments) |
| PTS POI and PTS HSM | Payment terminals, PIN pads, card readers and hardware security modules | Device vendors | PCI-recognised laboratory, then the approved device list (see PCI PTS) |
| Mobile Payments on COTS (MPoC) | Contactless and PIN acceptance on ordinary phones and tablets | Solution providers | PCI-recognised laboratory, then a listing (see PCI MPoC) |
| Secure Software and Secure SLC | Payment software and the vendor’s software development lifecycle | Software vendors | Secure Software or Secure SLC Assessor; these replaced PA-DSS, retired on 28 October 2022 |
| Token Service Provider (TSP) | EMV payment tokens | Token service providers that generate and issue EMV payment tokens | Validation requirements set by the payment brands (see PCI tokenisation) |
Most businesses only ever deal with PCI DSS; the others reach them mainly when they choose a listed terminal, solution or software product.
Which PCI assessor programmes exist, and what does each sign?
Each standard has its own assessor programme. PCI SSC trains and qualifies the assessor companies and their staff and lists them publicly, so you can check any firm’s approval on the PCI SSC assessor listings before you hire it.
| Programme | Who holds it | What they assess or sign |
|---|---|---|
| Qualified Security Assessor (QSA) | Independent QSA companies and their qualified staff | PCI DSS Reports on Compliance and AOCs for merchants and service providers; they can also support and sign SAQ-based assessments |
| Internal Security Assessor (ISA) | Staff of the organisation being assessed, trained by PCI SSC | Internal PCI DSS assessments for their own employer, where the payment brands accept them |
| Approved Scanning Vendor (ASV) | Approved scanning companies | External vulnerability scans every three months under Requirement 11.3.2 |
| PCI Forensic Investigator (PFI) | Approved forensic firms | Investigations after a suspected or confirmed card data compromise |
| Qualified PIN Assessor (QPA) | QPA companies and their qualified staff | PCI PIN security assessments |
| Card Production Security Assessor (CPSA) | CPSA companies and their qualified staff | Card Production and Provisioning assessments |
| P2PE Assessor | Qualified assessor firms | P2PE solutions and components submitted for listing; P2PE applications need a P2PE Application Assessor |
| 3DS Assessor | Qualified assessor firms | Assessments against the 3DS Core Security Standard |
| Secure Software and Secure SLC Assessors | Qualified assessor firms | Payment software and vendor lifecycles submitted for listing |
| KMO Assessor | Qualified assessor firms | Assessments against the KMO standard |
| PCI Professional (PCIP) | Individuals | A personal credential; it does not qualify the holder to assess |
Sovereign Secure holds five of these approvals: QSA company, Qualified PIN Assessor, Card Production Security Assessor, P2PE Assessor (Europe and USA) and 3DS Assessor, covering PCI DSS, PCI PIN, card production, P2PE solutions and components, and PCI 3DS. The other programmes are described here for information only.
What is the PCI SSC Global Executive Assessor Roundtable (GEAR)?
GEAR is an advisory group of senior executives from PCI assessor companies. PCI SSC created it in 2018 as a direct line between the leadership of assessor companies and the Council’s own leadership. Members advise on the assessor programmes, including training content and qualification requirements, meet quarterly and take part in Council projects when asked.
Membership is capped at 35 companies. The Executive Committee chooses members from eligible nominees for two-year terms, using criteria the Council publishes, including how long a company has been an active assessor and how many assessor programmes it takes part in. Sovereign Secure is a GEAR member for 2026 to 2028. GEAR advises the Council on how its programmes run; it does not change how any individual assessment is carried out or judged.
Are PCI standards regulations or law?
No. PCI standards are industry standards, enforced by contract through card brand rules and your merchant agreement, not by law. “PCI regulations” or “PCI rules and regulations” usually means those brand rules: merchant levels, validation deadlines and the fees acquirers charge when validation is missing or late.
No UK statute requires PCI DSS. Data protection law still applies, though: card data linked to an individual is personal data, and UK GDPR requires appropriate security for it. A card data breach can therefore raise regulatory questions as well as contractual ones, as our guide to GDPR and PCI compliance explains.
What do people mean by “PCI data”?
“PCI data” is shorthand for the data PCI DSS protects, which the standard calls account data: cardholder data, led by the primary account number (PAN), and sensitive authentication data such as full track data, card verification codes and PINs. “PCI data compliance” means meeting PCI DSS wherever that data is stored, processed or transmitted, and for any system that could affect its security.
Across the wider family, other standards protect the same data at different stages. PIN Security covers PINs and the keys that encrypt them, Card Production covers card data and keys while cards are made and personalised, and P2PE covers card data from the terminal to the point of decryption. Our guide to what counts as PCI data lists each data element and whether you may store it.
