Patsy Lindamood's Review Sourced from Google
Our firm switched to Xvand in mid-2025 after realizing our growing information security and network needs had outpaced our former MSP. Xvand immediately stood out for their expertise, depth of staff, and strong commitment to cybersecurity. They partnered with us to redesign our network, support our entire workstation fleet, and manage our many third party integrations.Since onboarding, Xvand has become a trusted and responsive IT partner. Their team is professional, knowledgeable, and genuinely invested in understanding how we run our business—not just our technology. Our staff consistently praise their fast, effective support, and I rely on their skilled team for more complex IT projects.With Xvand, I’m confident our clients’ information is protected, and our systems are continuously improving. They take care of the day-to-day challenges so I can focus on strategic initiatives that move our business forward.

I can't say enough good things about Xvand. Their team is responsive, knowledgeable, and committed to solving IT support and service issues quickly and efficiently. Both their Help Desk and Projects teams are easy to work with and take care of clients with professionalism, kindness, and dedication. What sets them apart are their people and their commitment to serving their clients with integrity and excellence. I'd recommend them to anyone looking for support with their ongoing IT needs, projects or to outsource IT operations.

J.T was really awesome. I like that he could help me, help him so that he could get it right to help me. That was awesome! Even after our communication got disconnected, in the space of the 'username' him and I were communicating, writing each other messages and that was super cool to connect with someone like that half way across the world. We were in proper sync! Great job J.T!
