Who we work with

IT support for Waldorf businesses

Waldorf is where much of Charles County does business, and our clients here look like the county: medical and dental practices, contractors who support the Navy at Indian Head and Pax River, auto dealers along Crain Highway, professional offices and nonprofits. Most have no full-time IT person, or one person who needs backup.

See how we work with healthcare practices, government contractors, auto dealers, construction companies, nonprofits and small businesses.

Co-managed IT

Already have an IT person? We can back them up. Talk to us about what that looks like.

How switching works

Build it. Manage it. Prove it.

Build it

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.

Manage it

Your team calls or emails one help desk. Every managed device is patched monthly, monitored and backed up.

Prove it

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.

Onsite in Waldorf

Down the road, not across the state

Our office is on Leonardtown Road, so onsite visits in Waldorf, St. Charles, White Plains and Bryans Road are a short drive, 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.

Local resources

Tech resources for Waldorf businesses

Internet providers in Waldorf

Federal broadband data (FCC, December 2025) shows fiber from Verizon across most of Waldorf and from Xfinity in parts of it, Xfinity cable almost everywhere, plus fixed wireless from T-Mobile, AT&T and Verizon 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.

Power outages

Waldorf is served by SMECO (Southern Maryland Electric Cooperative). Report outages and check restoration at smeco.coop/outage. 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.

Retiring old computers

Charles County runs recycling centers, including one on Billingsley Road in Waldorf, but Maryland's permanent electronics drop-off sites are generally for residents, so business equipment usually goes to a commercial recycler or a manufacturer take-back program. 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. County drop-off questions: the recycling hotline, 301-932-5656.

Moving or opening an office

Internet, phones, cabling and moving every computer can take weeks to line up, so start early. See our IT office relocation services.
