Company profile
researched Aug 2026StackGuardian is a Mechelen, Belgium-based cloud-native software company offering an infrastructure automation and orchestration platform for enterprise infrastructure, DevOps and security teams. The product spans four functional areas: automatically discovering unmanaged cloud resources and converting them into version-controlled Terraform or OpenTofu code (marketed as SGCode); enforcing security, compliance and cost policies as code; orchestrating provisioning, updates and CI/CD pipelines with workflow automation and granular RBAC (SGOrchestrator); and detecting drift, auditing changes and reporting on infrastructure posture.
The platform's building blocks include reusable multi-cloud infrastructure templates with version-control integration and lifecycle management, stack management with dependency and state tracking, rollback and cost tracking, workflow orchestration with approval gates and multiple trigger paths (self-service UI, GitOps, API, SDK and a Terraform provider), a policy engine supporting OPA/Rego and the company's own Tirith policy framework with warn/approve/fail actions, and analytics covering cost optimisation, security insights and compliance reporting. The company positions the platform as complementary to existing toolchains, integrating natively with AWS, Azure and Google Cloud, GitHub, GitLab, Bitbucket and Azure DevOps, ServiceNow and Backstage, and Checkov, and supporting additional IaC tools (Pulumi, Crossplane, CloudFormation, Ansible, Helm, Terragrunt) and security scanners (Snyk, Wiz, Aqua, Orca, Prisma Cloud).
Founding story
StackGuardian was founded in 2022 by Karl Driesen (Co-Founder & CEO) and Akshat Tandon (Co-Founder & CTO) to address the difficulty platform teams face in governing provisioning as organisations adopt multi-cloud environments and Infrastructure as Code. The company's stated approach combines Infrastructure as Code with no-code orchestration so teams can provision secure, compliant and cost-efficient infrastructure while retaining speed and autonomy. Its management team is described as bringing leadership experience from AWS, Palo Alto Networks, Cisco and SAP.
Business model
StackGuardian sells a software platform to enterprises, offering a free start/free trial tier alongside paid plans and an enterprise sales motion ("Talk to an expert"). The platform is deployed alongside customers' existing cloud, VCS, CI/CD, ITSM and security tooling, with a private runner option for customer-side execution.
Platform pricing is published on the company's site with a free trial and a pricing page; enterprise engagement is handled through direct sales contact.
Traction
The company reports that its platform is used by enterprises including Siemens, RheinEnergie and Bpost, and it publishes a customer story on voestalpine group-IT using StackGuardian as the central platform to orchestrate Terraform-based deployments. Testimonials on the website come from executives at Synergics and RheinEnergie. Its open-source Tirith repository has 167 stars and 42 forks.
Latest developments
Following the September 2025 Series A, the company has focused on AI-driven infrastructure orchestration, publishing material through 2026 on codifying legacy Azure infrastructure with SGCode, agentic IaC for drift detection, GitHub-driven Terraform workflows, and OpenTofu versus Terraform. Its product is presented in two named modules, SGCode and SGOrchestrator, and its public repositories (Terraform provider, private runner, SDK, Tirith) were updated in August 2026.

Market position
StackGuardian positions itself as an enterprise IaC management platform and an alternative to Terraform Cloud for multi-cloud enterprises, emphasising native support for both Terraform and OpenTofu, policy enforcement and codification of pre-existing infrastructure. Its investor TIN Capital frames it within European cybersecurity and security technology.
Stated differentiators include AI-powered discovery and conversion of unmanaged (brownfield) cloud resources into IaC at scale, native support for both Terraform and OpenTofu, a proprietary open-source policy engine (Tirith) alongside OPA, multi-trigger execution paths (self-service, GitOps, API, SDK, Terraform provider), and a no-rip-and-replace integration approach across existing developer portals, ITSM and security tooling.
Technology
The platform generates Terraform and OpenTofu code from discovered cloud resources using AI, and manages state, drift detection and rollback. Governance is implemented through OPA/Rego policies and StackGuardian's own SG Policy engine, Tirith, an Apache-2.0 licensed Python project (167 stars, 42 forks on GitHub) that evaluates plans in GitHub Actions workflows, protects sensitive values and enforces centralised policies. Additional tooling includes a Go Terraform provider, a Go SDK, a shell-based private runner (sg-runner), and sg-dr release binaries for recovering StackGuardian-managed infrastructure when the service is unavailable. The company describes an agentic "observe-detect-plan-validate" loop for continuous drift and policy-gap detection.
Go-to-market
The company combines self-service entry points (free start/free trial) with direct enterprise sales and a dedicated head of sales and head of solution architecture. Marketing relies on technical content — guides and articles on Terraform, OpenTofu, policy-as-code and drift — customer stories, and open-source distribution of Tirith via GitHub Actions, a Terraform provider, SDKs and a Homebrew tap. Integration partnerships are cited with major cloud providers, version control systems and single sign-on vendors.
Enterprise cloud, platform, DevOps and security teams managing multi-cloud infrastructure and Infrastructure as Code, including large organisations with substantial existing (brownfield) cloud estates.
Geography
Headquartered at Kardinaal Mercierplein 2, Mechelen, Belgium, with Series A proceeds directed at expansion across Europe and the United States. One funding-data source lists the company's location as Brussels, Belgium.
History
Founded in 2022, StackGuardian built an IaC management platform and open-sourced components including the Tirith policy evaluation engine, a Terraform provider, a Go SDK and a private runner on GitHub. In September 2025 the company announced it had raised a total of $10 million, inclusive of its initial seed round, in a Series A led by TIN Capital with existing investors Volta Ventures and InvestLink participating, earmarked for expansion across Europe and the United States and for further AI development. Company publications through 2026 describe AI-driven codification of brownfield infrastructure, agentic IaC and a customer story with voestalpine group-IT.
