FXProof is a B2B SaaS for creating signed, verifiable proof documents from official exchange-rate data.
For each supported dataset and date, FXProof keeps the official source, rate context, document ID, payload hash, digital signature, and public verification path together in a reusable proof bundle. The resulting PDF can be stored with an invoice, expense, accounting entry, tax file, audit workpaper, or internal-control record, so the exchange rate can be reviewed later without rebuilding the evidence trail.
Supported official sources currently include the European Central Bank, HMRC, the Federal Reserve System, the Bank of Canada, and the National Bank of Kazakhstan.
Key capabilities include:
Users can inspect public proof samples, verify supported documents without an account, retrieve ready proof bundles through the web application, and automate supported workflows through the API.
FXProof does not provide currency exchange, payment, money-transfer, trading, investment, legal, tax, or accounting services. Official institutions remain the sources of the underlying reference rates; FXProof provides the proof document and evidence workflow around those data.
CGPulse is a multi-cloud governance platform for DevOps, security, and compliance teams managing Azure and AWS environments. It was built for the gap between enterprise CSPM platforms priced in five figures per year and free open-source scanners that leave you without workflow, ownership, or remediation tooling.
The platform continuously scans cloud resources against 621 policy rules - 305 Azure, 175 AWS, 16 cross-cloud, and 95+ organizational controls - mapped to 19 compliance frameworks: SOC 2, ISO 27001, HIPAA, GDPR, PCI DSS, NIST 800-53, CIS v8, CIS AWS v3, FedRAMP, NIST CSF, and ten more. Findings are surfaced with evidence trails, severity, and actionable remediation copy.
Key capabilities:
Pricing starts free for a single Azure plus single AWS account; paid Team is €99/month and Business is €299/month with self-serve Stripe checkout. Onboarding takes about 60 seconds - connect cloud accounts via OIDC and first scan runs immediately.

FXProof's answer
FXProof does not simply provide an exchange rate. It creates a signed, verifiable proof document that preserves the official source, dataset, date, document ID, payload hash, signature status, and verification details in one reusable evidence bundle. A recipient can later verify the proof through a public verification page. This makes FXProof suitable for accounting, tax, audit, compliance, internal-control, and dispute-review records where the rate must remain explainable and verifiable over time.
CGPulse's answer:
Three things. First, an MCP server. Claude or any MCP client can run compliance scans, read findings, and trigger auto-remediation through natural language. No other CSPM ships this. Second, public self-serve pricing (€99/€299/month, Stripe checkout, no demo required) in a category where the norm is six-figure enterprise contracts. Third, every finding ships with Terraform and Bicep templates so teams apply fixes through their own change management, not a vendor UI.
FXProof's answer
Most exchange-rate services focus on displaying rates, converting currencies, or providing raw API data. FXProof is designed for situations where a business must document which official rate was used and provide evidence that can be reviewed later.
Users receive a signed proof PDF, source attribution, verification metadata, and a public verification path. Previously accessed proof bundles can be reused and downloaded again, while the API allows the same evidence workflow to be automated. FXProof is therefore a better fit when the required result is not merely a rate, but a verifiable business record.
CGPulse's answer:
Price and speed to value. Wiz, Prisma Cloud, Orca typically start at $50k/year with six-week rollouts and sales gatekeepers. CGPulse is €99 to €299 per month with public pricing and a 60-second self-serve onboarding. You get 621 policy rules across 19 compliance frameworks (SOC 2, ISO 27001, HIPAA, PCI DSS, CIS v8), the same category coverage, without enterprise overhead. For teams preparing their first audit, that's the difference between starting this quarter or next year.
FXProof's answer
FXProof is intended for:
The common requirement is a repeatable way to document and later verify the official exchange rate used in an invoice, expense, accounting entry, tax file, audit workpaper, or internal review.
CGPulse's answer:
Small and mid-size DevOps and platform teams, typically 10 to 200 people, running production workloads on Azure and AWS. Often they're preparing for their first SOC 2 or ISO 27001 audit, or their first customer security review. Many have tried open-source scanners (Prowler, ScoutSuite) and found the detection useful but the workflow missing. Others have been quoted by enterprise CSPM and found it outside their budget. CGPulse is built for the gap between those two.
CGPulse's answer:
.NET 10 with Blazor Server for the portal. Azure Cosmos DB for tenant and scan data, Azure App Service plus Azure Functions for the backend, Azure Service Bus for scan orchestration. Cloud scanning uses the Azure ARM SDK and AWS SDK directly. No agents, no proxies. Stripe for subscription billing. MCP server built on the ModelContextProtocol.AspNetCore library. Hosted entirely in Azure North Europe with per-tenant Cosmos partition keys.
FXProof's answer
FXProof was created to solve a practical evidence problem. Official exchange rates are usually available, but businesses often have to collect the supporting evidence manually by saving webpages, copying values into spreadsheets, taking screenshots, or rebuilding the source trail months later.
These methods are difficult to reproduce and can leave a weak audit trail. FXProof was designed to connect the official source, date, exchange-rate context, signed PDF, document ID, payload hash, and verification process in one consistent workflow. The goal is to make an exchange-rate record easier to store, explain, share, and verify when it is reviewed later.
CGPulse's answer:
It started a year ago with a simple wish: one clear view of what was actually running across my Azure and AWS accounts. Not console-hopping, a real map. Once the map was working, the obvious next layer was security. Not "here's a VM" but "here's a VM and here's what's wrong with it".
What I kept wishing for was honest answers with honest fixes. Not a red light on a dashboard, but guidance you can act on. Real automation where it's safe, and clear "do this, then this" steps where it isn't.
So a small scanner became a rule engine. Rules became compliance frameworks. Findings grew actual Terraform, Bicep, and CLI you can run. Then AWS support landed on top.
CGPulse today is a multi-cloud governance platform built around three promises: Connect, Govern, Protect. Connect your Azure and AWS accounts and see every resource in one view. Govern with 621 policy rules across 19 compliance frameworks. Protect with auto-remediation where it's safe and IaC export where the change needs human review.
