CodeChef is a not-for-profit educational initiative started by Directi more than a decade ago. We started with a dream of seeing an Indian team winning a gold medal at the ACM ICPC World Finals. In its quest for the same, CodeChef has built a self-driven community of the world's best programmers. Today more than 1.3 million competitive programmers from 180+ countries learn from CodeChef. CodeChef has been hosting monthly programming contests regularly for 10 years now. Its platform has assessed 92 million+ code submissions to date, and over 30000 organizations are being impacted by CodeCheffers worldwide. It also organizes SnackDown - one of the world's largest global programming competition whose last edition drew participation from 140+ countries. Since 2017, CodeChef has started providing India's only industry-ready certification in Data Structures and Algorithms, and 1800+ programmers have been certified under the same.
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 โฌ99/month and Business is โฌ299/month with self-serve Stripe checkout. Onboarding takes about 60 seconds - connect cloud accounts via OIDC and first scan runs immediately.

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 (โฌ99/โฌ299/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.
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 โฌ99 to โฌ299 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.
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.
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.
