On-premises software usually means the application is installed on infrastructure that you control.

Historically, that meant a physical server sitting in your own server room. In practice today, it can also mean infrastructure hosted in the cloud, as long as the environment is still under your control rather than the vendor’s.

In this post, we’ll look at the pros and cons of choosing an on-premises GRC platform instead of a typical vendor-hosted SaaS deployment.

Pros of On-Premises Deployment

  • None of your data sits fully under the vendor’s control. If you own the server the data is stored on, you have more control over who can access it and how that access is managed.

That said, some vendors still require limited network connectivity back to their own services for license validation, telemetry, or support workflows. During vendor onboarding, it is worth auditing those connections carefully and confirming exactly what data is sent back to the vendor.

This can also help when a vendor does not cleanly meet your compliance requirements. In some cases, on-premises deployment lets you reduce exposure enough to make the deployment acceptable.

  • You can add extra security layers. On-premises deployment gives you room to enforce additional controls that many SaaS products do not offer out of the box.

Examples include:

  • VPN-only access
  • IP allowlisting
  • Additional network segmentation
  • Tighter logging and monitoring controls

If your internal security team already has mature infrastructure controls, this flexibility can be a real advantage.

  • It can help with data residency requirements. Some jurisdictions and sectors require certain categories of data to remain in a specific country or controlled environment.

For many organizations, GRC and risk management data may not fall under the strictest residency rules. But for government bodies, critical infrastructure operators, and some regulated organizations, local hosting may still be a practical or contractual requirement.

Cons of On-Premises Deployment

  • You own the maintenance, scaling, and hosting cost. When you control the infrastructure, you are also responsible for keeping it running.

That includes applying patches, monitoring uptime, renewing certificates, rotating backups, and planning for capacity and recovery.

If your team does not already have strong IT operations or DevOps capability, this can quickly become a burden or even a security liability.

You also carry the direct cost of servers, storage, backups, and related operational overhead.

  • Software updates can be harder to manage. In cloud-based platforms, vendors roll out updates automatically.

With an on-premises deployment, your team often needs to install or schedule updates manually. That creates more friction and increases the risk of falling behind on patches.

It also means new features, fixes, and security improvements may reach you later than they would in a vendor-hosted environment.

  • Support can be slower and more complicated. With SaaS products, vendors can often investigate issues directly.

When the system runs inside your own environment, the vendor may not have access to the logs, configuration, or surrounding systems they need to troubleshoot quickly.

Support can turn into a longer back-and-forth involving exported logs, screenshots, configuration details, and screen-sharing sessions.

The more customized your deployment is, the harder it usually becomes for the vendor to support it efficiently.

When On-Premises GRC Makes Sense

Choosing on-premises GRC is not about preferring older deployment models. It is about matching the platform to the constraints you actually have.

On-premises deployment makes sense when:

  • You need full control over data, infrastructure, and security layers.
  • Your country, regulator, or customers impose data residency requirements.
  • You already have internal infrastructure and capable IT or DevOps teams.
  • You need a level of customization that a standard SaaS product cannot provide.
  • You operate in a highly regulated or sensitive environment where isolation and auditability matter more than convenience.

It is not the right default for every team. But when those conditions apply, on-premises GRC can be the more practical choice.
