Dental practice case study Healthcare

Dental Practice Hits 99.9% Uptime

99.9% uptime maintained for 3+ years

Industry: Healthcare / Dental | Location: Gwinnett County, GA | Size: 15 to 20 employees across two locations

The Challenge

This two-location dental practice kept running into IT problems that slowed down patient care. Their old server crawled during busy appointment hours, so X-rays and patient records took forever to load. The practice management software crashed several times a month, and the front desk had to switch to paper and re-enter everything later. The bigger problem: there was no real HIPAA plan for their IT. Patient data sat on unencrypted drives, backups were spotty and never tested, and staff shared logins. Their old IT provider only showed up after something broke, and it often took more than 24 hours.

The Solution

We started with a full IT assessment and found 23 separate problems across both offices. Then we fixed them in phases so the practice could keep seeing patients. First, we replaced the failing server with cloud infrastructure on Microsoft Azure, so the practice software, imaging, and patient records worked from both locations with built-in redundancy. We put endpoint protection on every workstation and gave each staff member their own login with only the access their role needs. Encrypted backups now run every four hours with an off-site copy, and we did a full test restore in the first month to prove it worked. We also installed our remote monitoring tools on every device to spot failing hardware, software conflicts, and security issues early. Last, we set up the network to put imaging and practice software traffic first, which ended the slowdowns during busy appointment blocks.

The Results

  • 99.9% uptime for 3+ years since we finished the work
  • HIPAA safeguards in place across all systems, with documentation ready for an audit
  • Digital imaging load times reduced by 60% after network optimization and cloud migration
  • Backup recovery time dropped from "unknown" to under 2 hours with tested, automated restoration procedures
  • No more paper workarounds when systems crash, so staff spend their time on patients

Key Learnings

Dental offices tend to underestimate how much IT affects the patient experience. A 30-minute crash on a busy morning can push back appointments for the rest of the day. That's why break-fix is so expensive in healthcare. The repair bill is the small part. The real cost is downtime in a business that runs on a schedule. Monitoring, HIPAA-aligned security policies, and cloud infrastructure let the team stay focused on patients. And test your backups. A lot of practices think they're covered and only find out during an emergency that the backups were incomplete or corrupted.

Law firm case study Legal

Law Firm Secures Client Data

Zero security incidents in 5+ years

Industry: Legal Services | Location: Metro Atlanta, GA | Size: 10 to 15 employees

The Challenge

This established law firm handles sensitive cases: personal injury, family law, and estate planning. Its IT had grown piece by piece over the years with nobody really in charge of it. Consumer-grade routers, old workstations, and an aging file server holding years of confidential case files. Attorneys emailed privileged documents without encryption, and the only document system was a shared drive with messy folders. No system had multi-factor authentication, and several former employees still had working logins. The firm had never had a major breach, but leadership knew their luck wouldn't last, especially with bar associations and malpractice insurers looking harder at law firm security. Then a hard drive failed on the file server and it took a week to recover documents. That's when they called us.

The Solution

We started with a security audit that documented every access point, user account, device, and data flow in the firm. Right away we shut off every old login from former staff and turned on multi-factor authentication everywhere: email, VPN, cloud services, and workstation logins. We replaced the old file server with a secure cloud document system with detailed permissions, version history, and full audit logs, so the firm can see who opened which file and when. We set up encrypted email that works inside the attorneys' normal workflow. A business firewall with intrusion detection replaced the consumer router, and we split guest Wi-Fi off from the firm's internal network. Every device got endpoint detection and response (EDR) software for real-time threat monitoring. Encrypted backups now run daily with an off-site copy and a test restore every quarter. Last, we ran a security awareness training for the whole staff on phishing, passwords, and handling documents safely.

The Results

  • Zero security incidents in 5+ years since the network overhaul and security implementation
  • 100% of client communications encrypted, built right into the email workflow they already used
  • Full audit trail on all document access, supporting compliance with bar association data handling guidelines
  • Backups tested every quarter. The firm can restore any file to any point in the past 90 days.

Key Learnings

Law firms hold some of the most sensitive data of any small business, and a lot of them still run on consumer-grade security. A breach can mean bar discipline, malpractice claims, and clients who don't come back. Two of the cheapest fixes are also two of the best: turn on multi-factor authentication and shut off old logins. Those two steps alone block a lot of common attacks. Encrypted email and real document management are basic requirements for any firm handling privileged information. And security is never one and done. It takes ongoing monitoring, regular staff training, and a fresh look as threats and the firm's tech change.

Transportation company case study Logistics

Fleet Company Cuts IT Costs 45%

45% reduction in annual IT spending

Industry: Transportation / Logistics | Location: Gwinnett County, GA | Size: 25 to 30 employees, fleet of 40+ vehicles

The Challenge

This regional fleet and logistics company was losing money on IT and didn't know it. They called a local tech every time something broke, and things broke a lot. Dispatch ran on a single server with no backup, so any server problem stopped fleet coordination cold. Their old landlines billed long distance by the minute, which cost thousands of dollars a month in driver and client calls. Dispatchers worked out of spreadsheets that were easy to get wrong and hard to scale. The fleet had grown from 15 to 40+ vehicles in a few years, but the IT hadn't kept up. Management spent an estimated 10 to 15 hours a month on IT problems, time they should have spent running the business. Add up the service calls, phone bills, lost time during outages, and one-off software purchases, and the yearly IT bill was big and growing every quarter.

The Solution

We started with a full cost review of what they were already spending: every service call, phone bill, software license, and hour of management time lost to tech problems. That showed the real cost of break-fix and gave us a baseline to measure against. Then we moved them to a managed IT agreement with one predictable monthly fee for monitoring, maintenance, and support. We moved the old dispatch server to a cloud platform, which added redundancy, gave field supervisors remote access, and made it easy to grow with the fleet. We replaced the phone lines with a 3CX VoIP system over SIP trunking. That wiped out long-distance charges and put drivers and dispatchers on one system that works from desk phones, cell phones, and computers. We also added a managed firewall and put every device on our remote monitoring platform so we catch most issues before they cause downtime.

The Results

  • 45% reduction in total annual IT spending compared to the previous break-fix model and legacy phone system
  • Phone costs dropped by over 70% after switching from traditional lines to VoIP with SIP trunking
  • No more dispatch downtime. Cloud-based operations keep running even if the office loses power or internet for a while.
  • Management reclaimed 10-15 hours per month previously spent troubleshooting and coordinating with break-fix technicians
  • Scalable infrastructure that has accommodated fleet growth without requiring additional capital expenditure

Key Learnings

Break-fix gets expensive fast for a growing business. When IT costs are spread across service calls, phone bills, and lost time, the total is often way more than a managed services agreement. But no single invoice is big enough to raise a red flag, so nobody adds it up. Transportation and logistics companies feel this the most because everything runs on real-time communication. When systems go down, trucks sit and deliveries get missed. Switching to VoIP is one of the fastest-payback upgrades for any business still on old phone lines, especially with drivers or high call volume. Moving dispatch to the cloud cuts costs and makes operations sturdier too. The team can keep working from anywhere with internet, which matters for a business that can't afford downtime.

CPA firm case study Finance

CPA Firm Survives Tax Season Without Downtime

100% uptime during peak tax season

Industry: Accounting / Financial Services | Location: Lawrenceville, GA | Size: 8 to 12 employees

The Challenge

For accounting firms, tax season is the Super Bowl. Months of tight deadlines where every hour counts, and downtime means missed filings and unhappy clients. This CPA firm had lived through exactly that. Their server ran the tax software, client files, and accounting platform, and it slowed way down every tax season when several preparers opened big files at once. The year before, the server died in the first week of April. It was down for two days while a break-fix tech found a replacement drive and rebuilt it from a backup that turned out to be three days old. The firm lost about 40 billable hours and had to push deadlines for several clients. On top of that, their client portal was old and hard to use, so a lot of clients just emailed Social Security numbers, W-2s, and bank statements as plain attachments. The firm knew that was risky but had nothing better in place.

The Solution

We started working with the firm six months before the next tax season so every change would be in, tested, and stable well before the January to April crunch. We moved their core systems to Microsoft Azure and put the tax software and accounting platform on cloud-hosted virtual desktops that scale up during tax season and back down in the quieter months to save money. Backups now run every two hours during tax season (every six hours the rest of the year) with point-in-time recovery, so the firm can restore to within two hours of a failure instead of losing days of work. We set up a new client portal with two-factor authentication so clients upload documents through an encrypted channel instead of email. We also set up 24/7 monitoring with tighter alerts during tax season, so slowdowns, storage limits, or security warnings get flagged to our team right away instead of waiting for someone to call. Before each tax season we load-test the system to find bottlenecks early.

The Results

  • 100% uptime during peak tax season across three consecutive years since implementation
  • Zero data loss. Automated backups with two-hour recovery points replaced the old, unreliable backup process.
  • Client portal adoption reached 85%, virtually eliminating the practice of emailing sensitive financial documents
  • System performance remained consistent even with all preparers accessing tax software simultaneously during peak filing periods
  • Predictable IT costs. The firm went from surprise break-fix bills to one flat monthly fee.

Key Learnings

Seasonal businesses have a tricky IT problem. Their systems have to handle peaks that can be several times normal load, and a failure during a peak costs way more. The cloud fits this well because it scales with demand. You don't have to buy for the peak (wasted most of the year) or for the average (not enough when it counts). For CPA firms, cloud apps, frequent automated backups, and monitoring together turn tax season from an IT worry into something you barely think about. The client portal shows something else too: security works best when it's also the easy option. Make the secure way the convenient way and people actually use it. Last tip: bring in IT help well before tax season, not during it.
