PCI-DSS, edge and cloud security & cost audit

Card data, a growing attack surface and a cloud bill nobody owns tend to arrive together. An infrastructure and security review looks at PCI-DSS scope, the edge and WAF layer, access control, cluster configuration and spend, and gives you a readiness gap list and the cost changes worth making.

PCI-DSS readiness review for a fintech or e-commerce startup

A startup is about to take card payments directly or faces its first PCI-DSS assessment.

Map where cardholder data flows, check network segmentation, secrets, access and logging, and look at the edge controls in front of payment endpoints.

You get

A scoped gap list, a remediation plan in order, and the architecture changes that shrink PCI scope.

PCI-DSS and zero trust across cloud and edge for a large e-commerce platform

A large e-commerce SaaS platform handling card payments needed PCI-DSS compliance across a multi-cluster cloud estate and its edge layer. One of our experts reports leading the PCI-DSS programme and a zero-trust model spanning cloud and edge, as part of a head-of-infrastructure role. Outcome: compliance work carried as an infrastructure programme rather than a paperwork exercise.

Kubernetes and AWS cost review

The cloud bill grows faster than traffic.

Review node pools, autoscaling (including Karpenter), idle and non-production environments, data transfer and storage, and how capacity changes are managed.

You get

A prioritized savings plan with the risk of each change to peak capacity spelled out.

Edge drift audit: when incidents come from drift plus automation

Many modern incidents aren't one bad deploy. They come from drift plus automation: fragmented caches, generic rate limits that block real users, WAF exceptions that pile up, auth storms and scraping.

Review the edge, WAF, rate-limit and cache config against real traffic, find where drift has crept in, and propose guardrails so automation stops amplifying it.

You get

A ranked findings list with concrete config changes and a drift-prevention checklist.

SOC 2 / ISO 27001 readiness review for a small SaaS

An enterprise prospect asks for a SOC 2 report.

Check access control, logging, change management, backups, incident process and vendor list against what auditors will ask, and separate engineering gaps from paperwork.

You get

A gap list and an order of work, with the engineering controls first.

Cloud cost reduction through application-level changes

Cloud bills grow faster than revenue. Beyond the usual right-sizing, reserved capacity and cleanup, one of our experts looks at how the application itself works, because that's where the biggest savings usually hide. Initial findings come within a few days with read-only access. In their experience, first-time optimizations usually save at least a third of the bill and often around half, without hurting uptime.

Questions buyers ask

How do you get a startup ready for PCI-DSS?+
First reduce scope: keep card data out of your systems with a hosted payment page or tokenization wherever possible. Then review what remains: network segmentation, access control, logging, key management and the edge layer. A readiness review tells you which requirements apply and where the gaps are before an assessor does.
Can a security review also cut our cloud bill?+
Often, yes. The same review that maps your clusters, edge and access also finds idle capacity, oversized nodes and missing autoscaling. Cost findings are listed separately so they can be acted on without waiting for the security work.
Who can audit our edge and WAF setup when production incidents keep coming from config drift?+
Invental's network includes an infrastructure and security leader who audits edge layers for exactly this: fragmented caches, generic rate limits that hit real users, WAF exceptions that have piled up, and auth storms or scraping. The output is a prioritized list of config fixes and the automation guardrails that stop drift from coming back.

How it works

  1. Tell us what you need — the repo or system, the question, and the deadline.
  2. We match an expert from the network, with a second reviewer where it helps.
  3. Scoped work, contracted through Invental — review per pull request, a fixed-scope audit or architecture review, or ongoing capacity.
