When does building GRC Automation make sense?

Building is most defensible for early-stage companies pursuing a single framework on a narrow, well-documented stack. AI tooling has made custom evidence collector generation faster, and cloud provider compliance exports can cover a meaningful portion of SOC 2 requirements without a full platform. The risk is that single-framework custom solutions often don't scale to multi-framework programs without significant rework.

When does buying GRC Automation make sense?

Buying earns its keep when you're pursuing multiple frameworks simultaneously, need a polished auditor portal, or have a broad SaaS and cloud stack where maintaining custom connectors yourself would rival vendor cost. The connector maintenance burden is the primary value — that's what the annual fee is paying for.

Should you build or buy GRC Automation (Compliance Automation)?

GRC Automation (Compliance Automation) software automates the evidence collection, control monitoring, and audit reporting required to achieve and maintain security certifications like SOC 2, ISO 27001, HIPAA, and PCI DSS. It connects to cloud infrastructure, SaaS tools, and CI/CD pipelines to pull compliance evidence automatically, reducing the manual effort of assembling audit artifacts.

The build-vs-buy decision for GRC Automation turns on whether the connector maintenance burden across your cloud and SaaS stack justifies a vendor platform versus AI-assisted custom evidence collectors for the frameworks you actually need; the specifics of how many frameworks you're pursuing and how fast your auditor portal requirements are growing decide it.

When building GRC Automation (Compliance Automation) makes sense

The build case for compliance automation has gotten more credible with AI tooling. Custom evidence collectors for specific cloud services and SaaS applications can be generated faster than they used to be, and a team pursuing its first SOC 2 Type I for a stack primarily on AWS can leverage cloud provider compliance exports without a full GRC platform. The path is most defensible for early-stage companies pursuing a single framework where the connector catalog and auditor portal polish of vendor platforms aren't required — a well-organized evidence repository and a clear control mapping is often sufficient for an initial audit. Sprinto's pricing pressure and the general commoditization of single-framework compliance automation show that the category is compressing from the bottom. The risk is underestimating how the compliance program matures: a self-built system that covers SOC 2 Type I often doesn't scale to Type II or ISO 27001 without significant rework.

When buying GRC Automation (Compliance Automation) makes sense

Buying earns its keep when you're pursuing multiple frameworks simultaneously, when you need a polished auditor portal that external auditors can access directly, or when your evidence collection requires connectors across a broad cloud and SaaS stack. The vendor's primary asset is the integration catalog — Vanta and Drata maintain connections to AWS, GCP, Azure, GitHub, Okta, Jira, and dozens of other tools, updated as those vendors change their APIs. That ongoing maintenance burden is what you're paying for. The multi-framework argument is the strongest case: a team pursuing SOC 2 and ISO 27001 simultaneously gains more from a shared evidence collection infrastructure with framework-specific control mappings than they would from two separate custom-built systems.

The compliance automation category is split by use case. Vanta and Drata built their platforms around continuous evidence collection, with hundreds of integrations that pull proof artifacts from cloud infrastructure, SaaS tools, and CI/CD pipelines automatically. That connector maintenance burden is real and ongoing. Buying earns its keep when you're pursuing multiple frameworks simultaneously, when you need a polished auditor portal for a formal audit, or when your engineering team's time is better spent elsewhere than building and maintaining evidence collectors.

The build case has gotten more credible. AI tooling can generate custom evidence collectors for specific tools faster than it used to, and Sprinto's positioning around multi-framework coverage at a lower price point shows the category is compressing. Teams pursuing a single framework, particularly SOC 2 Type I for the first time, may find that a lightweight custom solution built on existing cloud provider compliance exports covers enough ground to get through an audit without a full platform. The question is whether that scope holds as the compliance program matures.
