PCI DSS Gap Analysis for Payment Infrastructure That Actually Works.

Most fintechs find their compliance gaps during the QSA assessment or acquirer due diligence. By then you're looking at months of delay and six figures of rework. Know exactly where you stand - before anyone else asks.

Why this exists

The Compliance Gap Nobody Warns You About

Generic AWS cost guides and cloud consultants do not understand payment infrastructure. They flag required PCI DSS headroom as waste. They miss cardholder data scoping issues that QSAs catch immediately. They do not know the difference between a security group rule that is fine and one that fails Requirement 1.

The result: most funded fintechs walk into their first QSA assessment or acquirer conversation without knowing where their gaps are. The gaps exist. They are findable. Finding them late is expensive.

3-6 months of delay

The average fintech that discovers compliance gaps during due diligence loses 3-6 months on its go-live timeline while fixes are made under pressure.

10x more expensive to fix late

Compliance remediation found during a QSA assessment costs significantly more than the same work done before the engagement starts.

Acquirer applications rejected

Barclaycard, Worldpay, and Lloyds Cardnet reject fintech applications for gaps you could have found and fixed weeks earlier.

Product tour

See the platform in action

Keep the animated UX, but shift the framing toward business outcomes: PCI readiness, acquirer confidence, quantified risk, and architecture decisions that can be defended to engineering, finance, and audit.

Architecture Decisions That Are Clear, Documented, and Defensible

This is the payment-stack visual the homepage was missing. It now speaks to operating decisions, not just technical telemetry: where risk sits, what finance can recover, and what engineering needs to tackle next.

Here is what leadership can see about the payment stack today.One view for compliance readiness, spend recovery, and engineering priorities.

How It Works

The animations stay intact. What changes is the framing: each step now explains how Sync moves a payments team from uncertainty to a clear remediation and delivery plan.

1

Scope your payment stack

Start with the commercial and delivery context: payment model, processing footprint, PCI target, go-live timeline, and engineering capacity. The visual stays product-led, but the questions now frame the business risk clearly.

Surface the blockers fast

The animated analysis view shows the value well, so that stays. The message shifts to what leadership cares about: which gaps slow down acquirer approval, create remediation cost, or expose control weaknesses before audit.

Give leadership one clear view

This is the payment-stack visual you called out. It should read less like a cloud console and more like an executive operating view: compliance readiness, recoverable spend, critical risks, and the next actions that matter.

Review decisions, not just findings

Keep the consultation animation because the interaction works well, but position it as a working session around evidence, architecture trade-offs, and delivery decisions rather than generic consultancy branding.

Built for How Payment Infrastructure Actually Works

Most compliance assessments are built for generic cloud environments. Sync Your Cloud is built specifically for fintech payment infrastructure - which means it understands the difference between required PCI DSS burst headroom and genuine waste, what cardholder data environment scoping looks like in your architecture, and what a QSA actually checks.

6 years of banking operational experience

Not theoretical compliance knowledge. Practical experience from NatWest operations with a clear understanding of how regulated banks are governed and scrutinised.

PCI DSS v4.0.1 including Requirement 8.6

The current standard including new requirements for automated agent accounts that many compliance assessments still miss.

Built for acquirer due diligence

Output is structured the way Barclaycard, Worldpay, and Lloyds Cardnet expect to receive it - not only technically accurate, but audit-ready.

Start Free. No Account Needed.

Three assessments built for payment engineering teams. Run them before you commit to membership.
