Much of St. Mary's County works around Naval Air Station Patuxent River, so many of our clients here are defense contractors and the professional offices that support them. We also work with healthcare practices, contractors and nonprofits around Leonardtown and MedStar St. Mary's Hospital.
See how we work with government contractors, healthcare practices, construction companies, nonprofits and small businesses.
Help desk, monitoring and monthly patching of every managed device.
Managed cybersecurity, from multi-factor authentication (MFA, a second sign-in step that makes a stolen password far less useful) on every account to firewalls and security awareness training.
Managed backup and disaster recovery, with test restores so you know your data comes back.
Setup, security settings, licenses and migrations.
New offices, rewiring, Wi-Fi and network upgrades.
Already have an IT person? We can back them up. Talk to us about what that looks like.
If your contracts include CMMC or DFARS requirements, we handle the CMMC remediation work: putting the controls in place, running them day to day and keeping the evidence. We also reimage computers that have held Controlled Unclassified Information (CUI) and retire old equipment with drives sanitized following NIST SP 800-88.
Our work supports your compliance program. It doesn't guarantee compliance, certification or audit results.
We start by documenting what you have: devices, network, accounts, licenses and backups. Then we fix the urgent gaps first, including MFA on every account, admin and email accounts included.
Your team calls or emails one help desk. Every managed device is patched monthly, monitored and backed up.
You see the work. We send monthly patch reports, and every quarter we walk through your backup reports and restore-test results with you in a technology business review.
We serve Lexington Park, California, Leonardtown, Great Mills and Hollywood from our Waldorf office, and two hours of travel is included with every onsite visit. Most problems we fix remotely; when it needs a person at your desk, we come to you.
Your support comes from ITAssurance staff. Outside our office hours (8:30am to 5pm, Monday to Friday), call our after-hours number and leave a message. It goes to our on-call technician.
Federal broadband data (FCC, December 2025) shows Breezeline cable across most of Lexington Park, fiber from Verizon and Xfinity in parts of it, plus fixed wireless from Verizon, T-Mobile and AT&T and satellite from Starlink. If your phones and cloud apps depend on one connection, a second connection from a different provider can take over when the first one drops. We recommend a backup internet connection for most offices, and we set it up and manage it for you.
St. Mary's County is served by SMECO (Southern Maryland Electric Cooperative). Report outages at smeco.coop/outage or 877-747-6326. A battery backup (UPS) on your firewall, network switches and server keeps a short flicker from taking your whole office offline. After a long outage, check that last night's backup actually ran; for our managed clients, we check.
St. Mary's County takes computers, laptops and servers free at its convenience centers, a program written for county residents, so business equipment usually goes to a commercial recycler or a manufacturer take-back program. County questions: the Solid Waste Manager, (301) 863-8400. Before any computer leaves your office, its drive should be wiped or destroyed. Or we can handle it for you: we preserve the data you need to keep, sanitize or destroy the drives following NIST SP 800-88 (the federal guideline for media sanitization), recycle the equipment and give you a data destruction certificate. We also reimage computers that have held Controlled Unclassified Information (CUI) for government contractors.
Internet, phones, cabling and moving every computer can take weeks to line up, so start early. See our IT office relocation services.
