Resilience

Backups, testing, and observability from day one so failures are contained and recoverable.

About Us

Empowering IT Through Open-Source Principles

At opHUB, we're not your typical IT consultants. Our approach is built on the belief that technology should be a tool for empowerment, not a source of complexity. We focus on providing expert IT solutions that are rooted in open-source principles, ensuring your business operates with transparency, flexibility, and complete control over its data.

We understand that you value your independence. That's why we place a strong emphasis on avoiding vendor lock-in and prioritizing self-hosted solutions whenever possible. We believe your data and services should always belong to you. Our commitment to GDPR compliance and data privacy is a top priority, ensuring your systems are secure and your customer's trust is protected.

Our work is a partnership. We're proud to collaborate with your existing in-house teams or other consultants to create the best possible outcome for you. We see this not as a challenge, but as a benefit, allowing us to leverage all available expertise to build a robust and seamless IT infrastructure.

Most importantly, we're dedicated to training your team to manage your new systems with confidence. Our goal is to empower you with the knowledge to maintain full control of your IT, long after our initial work is complete.
