Automation and Artificial Intelligence
Local expertise for coastal operations
From riverfront shops on Indian River Drive to contractors near CR 512, Sebastian teams depend on reliable networks, cloud apps, and fast answers. We design and manage that foundation: business‑grade wired and Wi‑Fi for back office, guest access, POS, and voice; Microsoft 365 for email, Teams, and file sharing; and endpoint care with continuous monitoring, patching, and asset tracking. Coastal realities—concrete and metal construction, busy seasonal demand, marina and hospitality Wi‑Fi—are part of our planning. We standardize laptops and desktops, document everything, and streamline onboarding so devices, permissions, and MFA are ready on day one. Opening a new suite or modernizing an older building along US‑1? We handle cabling, access point placement, hardware procurement, and coordination with carriers and software vendors, delivering clear timelines, budgets, and minimal downtime.

If an incident occurs, our team isolates affected systems, restores clean data, coordinates with vendors or insurers, and explains what changed so your staff can return to work quickly. Need to satisfy customers, partners, or cyber‑insurance? We help you prove controls and stay compliant.
