Long Island managed IT services for businesses that cannot afford downtime
TDS Guardian delivers Long Island managed IT services from TeleData Services, a managed service provider (MSP) based in Hauppauge. It puts your systems in the hands of a team focused on protecting what matters most: your data, your uptime and your reputation. We prevent problems with proactive monitoring, network security and support designed around your business.
One plan for support, monitoring, security and Microsoft 365
TDS Guardian is TeleData Services’ managed IT service. Instead of calling someone when things break, you get a team that answers the helpdesk around the clock, protects every endpoint, keeps devices patched, watches your network through a 24/7 SOC and administers Microsoft 365 for you. It comes in three tiers, Guardian, Guardian Plus and Guardian Elite, so you pay for the coverage you need and move up as you grow.
A helpdesk your staff can call, and engineers who already know your network
Guardian puts Long Island managed IT services behind every workstation, server and Microsoft 365 account. Issues are logged, monitored and fixed before most users notice them.
- 24/7 remote helpdesk for every user
- Monitoring and patching on every endpoint
- Microsoft 365 administration and support
- The same team for the phones, the network and the cabling
Built for businesses that cannot afford downtime
Businesses without in-house IT

Companies with an IT lead but no security team

Regulated firms and government suppliers
Guardian Elite adds security awareness training, phishing simulations, dark web credential monitoring, Microsoft 365 and SaaS security monitoring and backup, user and identity monitoring, and cybersecurity coverage.
What is included in each tier
Every tier starts with the same core: 24/7 remote helpdesk support, managed endpoint protection, EDR, 24/7 SOC monitoring and response, patching, endpoint and network management, and Microsoft 365 administration. Guardian Plus adds email and vulnerability protection. Guardian Elite adds user security, Microsoft 365 and SaaS monitoring and backup, and cybersecurity coverage.
