An Exceptional Brooklyn IT Company

“CTS has been punctual and collaborative. They listen and are capable.”

“First, I want to say that the charging cart wiring installation was truly not an issue at all. Projects of this size and complexity always have moving pieces, and what matters most is having great partners who work together to find solutions. Your team’s flexibility, responsiveness, and willingness to jump in are exactly what make working with CTS such a wonderful experience. We are one team working toward the same goal, and I have always felt that from every interaction with all of you. I also wanted to take this opportunity to recognize you and the entire CTS team.
You guys are an incredible group of professionals. Over the past year, from helping us open MESA South Brooklyn to supporting our continued expansion, everyone we’ve had the pleasure of working with has been absolutely outstanding. Each of you is professional, knowledgeable, detail-oriented, responsive, kind, and genuinely invested in our success. The level of care you bring to your work does not go unnoticed. Our jobs are incredibly demanding, and having a partner like CTS makes what could be a stressful process feel organized, collaborative, and seamless. As Director of Operations, I work with many vendors and partners, and I can honestly say CTS has been one of the very best teams I’ve ever had the privilege of working with. Beyond the technical expertise, it’s your attitude, partnership, and commitment to doing what’s best for our school that truly set you apart. Thank you for everything you guys have done and continue to do for MESA. I am incredibly grateful for each of you. You guys are an exceptional team representing CTS. Looking forward to continuing our partnership for many years to come.”

“CTS currently provides our 24x7x365 Managed Detection and Response (MDR) and Endpoint Detection and Response (EDR) services. Their Security Operations Center is exceptionally responsive, identifying and remediating potential threats quickly—often before they have the opportunity to impact our business. Their proactive approach has significantly strengthened our security posture and helped us avoid disruptions that could have resulted in downtime or operational issues. Beyond security monitoring, we’ve engaged CTS on Level 1, Level 2, and Level 3 support activities. Whether it’s remote troubleshooting or coordinating on-site support, their technicians and engineers have consistently executed with confidence and professionalism. They have efficiently dispatched resources to our branch offices in Connecticut and Massachusetts when needed, ensuring issues were resolved promptly and with minimal disruption to our users. CTS has become a trusted extension of our IT team. They are currently assisting us with Microsoft 365 tenant migration projects, and we will also be working with them to manage our Microsoft 365 licensing going forward. Their expertise with Microsoft technologies and their ability to manage complex projects have been invaluable. What stands out most about CTS is their responsiveness, technical depth, clear communication, and commitment to customer success. Regardless of the size or complexity of the issue, their team takes ownership, follows through, and consistently delivers high-quality results. I would highly recommend Charter Technology Solutions to any organization looking for a dependable IT and cybersecurity partner.”
