Microsoft 365 security and AI governance for small businesses.
You didn't start your business to worry about hackers, data breaches, who has access to what, or what your team is pasting into ChatGPT. That's our job. We handle your security every month, remotely and without disrupting your day.
Sentinel Access Solutions was built for one reason. Small businesses deserve real security without the corporate price tag or the corporate complexity.
We start simple. One client at a time. We secure what you already have, lock down who has access to what, keep the AI tools connected to your business in check, and make sure your data is backed up.
As a small business owner myself, I know you don't have time to become a cybersecurity expert. You have a business to run. We handle the security so you never have to think about it.
We also work with businesses pursuing federal contracts, building the security foundation you need to compete and comply at that level.
No complicated onboarding. No tech jargon. Start on your own or with a conversation, and take it one step at a time.
Take the free 2-minute Security Check on your own, or book a free 30-minute consultation. The check is a quick self-assessment, not a technical audit.
With your written permission, we review your actual setup, including any AI tools, and show you what's exposed in plain English.
We secure your accounts, control who and what has access, protect your email, and back up your data. All done remotely.
Every month we review, manage, and report. You get a plain-English update on what we handled and what's next.
Sentinel 365 Secure protects your Microsoft 365 accounts, email, devices, and files. Sentinel AI Guard keeps the AI tools your team uses in check.
Microsoft 365 security, set up right and checked every month.
Default settings do not always match a business's risk. We review and strengthen Microsoft 365 configurations, document what is in place, and help you address gaps.
Includes full Microsoft 365 security configuration
We review access by role, help limit unnecessary permissions, and revisit access as employees and responsibilities change.
Includes Microsoft Entra ID & access controls
One wrong click on a fake email can be expensive. We turn on and tune Microsoft's email protection to catch phishing and fraud attempts, and show your team what to watch for when something slips through.
Includes Microsoft Defender email protection
We help enroll eligible work devices, apply security policies, and review their protection status, including for remote teams.
Includes Microsoft Intune device management
Ransomware, hardware failure, human error. We set up backups for your email and files and test that we can restore them, so you know your options before you need them.
Includes cloud backup setup & restore testing
Every month you get a plain English report on your security. No jargon. Just a straight answer on what we handled and what's next.
Includes monthly security report & review summary
Know which AI tools can see your business data, and keep them in line.
Explore AI security & governance →Copilot, ChatGPT, meeting note-takers, scheduling assistants. We review the AI tools and connected applications visible within the agreed assessment scope, including access to email, calendars, and files.
Includes AI tool & connected app inventory
AI tools see whatever they're allowed to see. We assess permissions against each tool's role and recommend least-privilege settings and safer file-sharing controls.
Includes Entra ID app permissions & SharePoint access review
A short, plain-English AI use policy: which tools are approved, and what information never goes into them.
Includes AI acceptable use policy
If an AI tool does something unexpected, you need to cut off its access fast, without relying on the tool itself. We document how, and who can do it.
Includes AI disconnect & response steps
Remote IT support, advanced security, and employee awareness are separately scoped options. You can start with Microsoft 365 security, AI governance, or an authorized assessment.
Help with sign-ins, Microsoft 365 apps, account setup, and remote troubleshooting. Physical printer or hardware problems may require someone on site.
Optional support plans with defined hours and response times
Explore endpoint alerts, vulnerability reviews, firewall or IDS findings, and incident readiness based on your systems and the coverage you need. Continuous 24/7 monitoring is not included by default.
Custom scope; specialized coverage subject to availability
Short virtual sessions on passwords and passkeys, phishing, work-from-home practices, safe file sharing, and responsible use of AI tools.
Optional quarterly awareness sessions and summary
We work with small businesses across the US, 5 to 50 employees, who handle sensitive client data and can't afford a full-time IT team.
Client confidentiality depends on who can open which files and inboxes.
Tax season fills inboxes with financial records and payment requests.
Patient information calls for tight sign-in and access controls.
Closings involve wire instructions, so payment-change scams are a real concern.
Client data moves between staff, partners, and more and more AI tools.
Crews work from phones and tablets, and federal work brings its own security requirements.
You don't need a big IT department to get hacked. You just need one employee to click the wrong email. One weak password. One person with access they shouldn't have.
We help identify and prioritize those gaps, then provide agreed security reviews and management services.
We secure and manage what you already have. No ripping anything out. No starting over.
Keep your Google email. We layer security on top of your existing setup to protect your network and your people.
We can help review identity and access controls relevant to your contract requirements; any formal compliance assessment is separately scoped.
We help you decide what AI tools can see, and what your team can put into them.
Get remote security support with responsibilities, review schedules, and response times clearly defined in your agreement.
No jargon. Just straight answers to what small business owners actually ask us.
Phishing, fake emails designed to trick someone into clicking a link or sending money, is one of the most common ways small businesses get hit. We turn on and tune Microsoft's email filtering to catch as much as possible, and set up multi-factor authentication so a stolen password alone usually isn't enough to get in. No filter catches everything, so we also help your team know what to watch for.
A breach can mean lost money, downtime, notifying clients, and in some industries, regulatory trouble. For a small business without spare cash or an IT team, recovery can be hard. Nobody can remove all risk, but the basics we set up (sign-in protection, access cleanup, email filtering, and tested backups) close the doors attackers use most often.
Antivirus is one layer of protection, but it only protects one device at a time and doesn't cover your email, your cloud files, your employee accounts, or who has access to what in your business. Real business security means protecting every device, every account, every email, and every file all at once. That's what we manage for you every month.
Yes, and this is exactly who we work with most. Microsoft 365 doesn't turn on every security setting by default. Many businesses run it without multi-factor authentication on every account, without email filtering tuned, and with file access nobody has reviewed. We take what you already have and secure it the right way. No ripping anything out, no starting over.
It depends on how it's connected. Microsoft Copilot can see whatever the person using it can already open, so messy file permissions become an AI problem. Apps connected to your email, calendar, or files may have been given broad access when someone clicked "Allow." We find what's connected, check what each one can reach, and trim it to what the job needs.
Yes. Sentinel AI Guard is available on its own. We review the AI tools your team uses and what they're connected to, write a simple AI use policy, and show you how to shut a tool off if you need to. If we spot access problems outside AI, we'll tell you, and what you do about them is your call.
The first step is cutting off its access, and that should never depend on the AI tool itself. We document how to disconnect each connected tool and who can do it, so you're not scrambling. Disconnecting stops further changes but doesn't undo what already happened, which is why limited permissions and tested backups matter too.
A lot less than recovering from a breach. Our monthly managed security services are designed specifically for small businesses, not enterprise budgets. Start with the free 2-minute Security Check or a free 30-minute consultation, so you know what you need before spending a dollar.
This is one of the most overlooked security risks for small businesses. When someone leaves and still has access to your email, files, and systems, that's a serious vulnerability. We manage your identity and access controls so that when an employee leaves, their access is removed the same day you tell us. The right people always have access to the right things. Nobody else.
Most small business owners we talk to say the same thing. They know they need better security but they don't know where to start and they don't have time to learn. That's exactly why we exist.
"You don't need to become a cybersecurity expert. You need a partner who can review your setup and explain practical next steps. That's what we do."
