What You Get
One service that covers the licenses, the protection, and the upkeep.
Most firms bought Microsoft 365 from a reseller years ago and haven’t heard from them since. We treat it as a living system, where the plans, the security, and the day-to-day management belong to one accountable team.
The Apps Your Office Already Runs On
Word, Excel, PowerPoint, Outlook, and Teams, plus OneDrive storage so files follow your people between the office and home. The tools your firm uses every day, licensed and set up properly.
Plans Matched To Each Person's Work
Your receptionist and your senior partner don’t need the same license. We sort out who needs web-based apps and who needs the full desktop suite, then build your seat list around real usage.
Proofpoint Filtering On Every Inbox
Spoofed senders, phishing attempts, and junk get stopped before your staff ever sees them. The convincing fake invoice never gets the chance to be convincing.
Intrusion Detection Watching Your Cloud
A security operations center monitors sign-ins and mailbox behavior around the clock. A login from somewhere your firm has never been gets flagged and investigated, not discovered weeks later.
Multi-Factor Authentication On Every Account
User accounts, admin accounts, no exceptions. And when your cyber-insurance renewal asks for proof, the documentation already exists.
Licenses That Match Your Headcount
People leave, roles change, add-ons pile up. We keep your seat count honest, so the bill reflects the firm you have today.
Migrations That Don't Take Your Office Down
Whether you’re leaving an old provider or cleaning up a messy setup, the move runs in planned stages with your existing mail flowing until the new environment is verified.
Help From Techs Who Know Your Setup
When something acts up, you reach people who already know your firm, and every quarter you get a short summary of what we handled and what we caught.
The Problem
Criminals don't need your safe, just your inbox.
Here’s an ordinary day at your office. A client emails tax documents to your CPA. A paralegal sends settlement details. Someone in accounting receives wire instructions for a closing. None of it feels risky, because it’s just email, the thing your firm does hundreds of times a day.
That’s exactly why it’s the target. Criminals don’t need to break into your building or crack your server. They need one employee to trust one message that looks like it came from a client, a bank, or you. Once they’re inside a mailbox, they read quietly, learn how your firm communicates, and wait on someone to send the critical information they’re after.
And here’s what makes it worse for most firms: nobody is actually watching. The company that sold the licenses set up the mailboxes and disappeared. Multi-factor authentication covers some accounts but not the admin login. Nobody has looked at the settings in years, and nobody would notice a foreign sign-in tonight.
Ask yourself the question an insurance auditor would ask: who is responsible for your firm’s email security? If the answer takes more than three seconds, you already know the problem.
Our Approach
The Brilliance SecureShield approach to Microsoft 365.
There are two ways to sell Microsoft 365. The common way treats it like a commodity: move the licenses, collect the margin, let the customer figure out the rest. It’s fast, it’s profitable, and it leaves firms like yours holding all the risk.
We chose the other way years ago, and we’ve never made an exception. Every Microsoft 365 environment we deploy includes Proofpoint filtering in front of the inboxes, intrusion detection behind them, and multi-factor authentication across every account. It’s not a premium tier or an add-on we upsell later. It’s the only version of the product we’re willing to put our name on.
Getting there starts with a short, free consultation rather than an order form. We look at how your people actually work, recommend the right plan for each seat, and put the per-user cost in writing before you commit to anything.
After that, the relationship is the product. The same techs manage your environment month after month and there’s no multi-year contract holding you in place. We earn the relationship every 30 days, and if we are not earning it, you are free to leave.
How it works
The Brilliance SecureShield System.
Most IT companies sell pieces. You buy antivirus from one, a firewall from another, voice from a third, and somebody else for “the rest” — and when something breaks, nobody owns it. SecureShield is the opposite: one team, one number, one accountable partner that designs, deploys, monitors, and maintains your entire stack month-to-month. You don’t have to know what’s broken. You don’t have to figure out who to call. You call us. We handle it.
Free on-site audit, no obligation
We come to your office, walk your network, and document exactly what you have, what’s working, what’s exposed, and what you’re overpaying for. You get a written assessment in plain English — yours to keep whether you sign with us or not.
The right-sized stack, priced down to the user
We build a clear plan that covers your network, security, M365, voice, devices, and backups. No bundling you into capability you’ll never use. You see exactly what’s included, what it costs per user, and what’s not — before you ever sign.
A clean transition without wrecking your firm
Phased onboarding with documented handoff from your old provider, tested backups, and a stabilization period. Your office keeps working through the switch. The “broken email and panicked staff” version of switching never happens.
Layered security that catches what one tool misses
Managed EDR, SIEM with 24/7 SOC monitoring, Proofpoint email security, DNS filtering, and immutable backups — all working together, all monitored by named techs who know your setup. Different layers, different engineers, no silver bullet, no single point of failure.

Why Computer Brilliance
A partner who owns your whole stack.
Most IT companies sell you a contract and disappear until something breaks. We do the opposite. We answer the phone, plan ahead, and clean up the mess before it costs you a client.
Recommended
Your IT heroes since 2007.
For nearly twenty years, CPA practices, law offices, independent pharmacies, and family clinics across Mississippi and the Gulf South have called the same Hattiesburg number for managed IT support — with the same owners and the same certified technicians answering every call.
Computer Brilliance has been a godsend to our practice from day one, stepping in right when our previous IT provider closed unexpectedly. We’ve now been with them almost two years, and they’re the most knowledgeable and helpful IT group we’ve ever dealt with. They’re always responsive both remotely and in-person for every issue — from a quick technical question to a printer install to a major network security upgrade. The icing on the cake is that they’re always a pleasure to work with. I’d highly recommend Computer Brilliance to any business looking for dedicated, skilled IT support.
Computer Brilliance is a wonderful IT company that truly values their clients. They work exceedingly hard to answer any and all questions as they arise. And they take the time to explain what’s happening for those of us who aren’t as familiar with the systems and software. I highly recommend any individual or business who has IT needs to give Computer Brilliance a try.
Jeremy and Computer Brilliance have been a fantastic partner for us in all things IT and security. If we have an issue, they’re very responsive and almost always have things back to normal the same day. Jeremy has been proactive about recommending the latest security measures to keep us protected. I’d highly recommend them to any small business looking for an IT and security partner. It’s like having our very own internal IT department.
Jeremy Graves and his team took over our IT management and security and totally nailed it. We were very outdated when they started, and they brought us up to date fast and at a very affordable cost. Thanks to them we’ve stayed efficient and safe from hackers — and it’s even let us bring on new customers who require a very high level of security. Their customer service is second to none, and they’re quick to help, which matters for a time-sensitive company like ours. Give them a call — it’ll be the best decision you ever made.
Honest answers
What owners always ask before they sign.
Let’s talk about price first, because you can buy Microsoft 365 licenses online in about ten minutes, and they’ll cost less than working with us. If licenses were the whole job, that would be the right move. But a license doesn’t filter a fake invoice out of an inbox, doesn’t notice a sign-in that doesn’t belong, and doesn’t answer the phone if something breaks. That’s what you’re paying for. After a free consultation, you’ll have the per-user cost in writing before you commit to anything.
Owners also worry the move itself will disrupt the office. That’s fair, and it’s why we don’t flip switches and hope. The new environment gets built and tested while your current email keeps running, your addresses and history come along, and nothing gets turned off until the new setup is proven. Your office keeps emailing the whole way through.
And if you figure a firm your size is too small to be a target, we understand the thinking, but these scams don’t work that way anymore. Fraudulent emails go out by the thousands, and a small office holding private information and client financial details is exactly the kind of place they’re meant to reach. Small doesn’t mean invisible, and that’s the part we help with.
Questions before yes
Frequently asked questions.
Don’t see your question? Give us a call — a senior tech, not a salesperson, will walk you through it.
It’s priced per user, and the right number depends on what each person in your office needs. Some seats only require email and web apps, while others need the full desktop programs, and every seat includes the security layer. So instead of quoting a number that might be wrong for your firm, we start with a short, free consultation, map out your users, and hand you the exact per-user cost in writing before you sign anything.
No, and most of our clients came to us in exactly this position. We take over your existing environment, document how it’s currently configured, fix the gaps we find, and manage it from there. Your addresses, your mail history, and your files all stay put.
The built-in protections are a starting point, and we use them. But the fraud aimed at professional services firms is specifically engineered to get past default filters. Layering Proofpoint in front of your mail and intrusion detection behind it means a message that beats one defense still has to beat the others.
This fear keeps a lot of firms stuck with setups they know are bad, so we built our process around it. Migrations run in planned stages, your current mail keeps flowing until the new environment is tested and verified, and your staff keeps working the whole way through.
No, and we’re upfront about why. Unprotected email at a firm that handles client funds and confidential records is a problem waiting for a date, and we’re not willing to be the company that sold it to you. If bare licenses are all you want, a reseller can help you. If you want email you don’t have to worry about, that’s us.
No. This runs on the same month-to-month agreement as everything else we do. We earn the relationship every 30 days, and if we are not earning it, you are free to leave.
The monitoring layer exists for exactly this moment. Unusual sign-ins and mailbox behavior get flagged to a security operations center, investigated, and contained. Then a tech you already know calls you and explains what happened and what we did about it, in plain English.
