Article Summary: Most IT problems don't appear out of nowhere. Backups quietly stop working, updates sit uninstalled for weeks, and accounts belonging to former employees stay active long after they've gone. This guide walks through a short monthly review that can catch these issues while they're still easy to fix.

The IT issues that cost businesses the most tend to develop quietly, without any obvious sign that something is wrong. The backup that eventually fails has often been quietly failing for weeks. The account a scammer uses to access a company's systems frequently belonged to someone who left months earlier. The software vulnerability that got exploited had a patch available long before anything went wrong.

None of this requires a technical background to catch. It just requires someone to look at the right things on a regular basis. A 30-minute monthly review surfaces these issues while they're still easy to fix, and getting there is simpler than it sounds.

Why Monthly Checks Are Worth the Time

A 2026 report from Verizon found that 31% of breaches started with attackers exploiting unpatched software, making it the most common entry point for attacks, ahead of stolen passwords. The same report found that the median time to fully resolve a known vulnerability has risen to 43 days.

That figure is worth sitting with. Most attacks use a problem that was already known, with a fix already available. Nobody had installed it yet. That gap between "patch available" and "patch installed" is where most breaches happen. A monthly check closes it.

The Six-Item Check

1. Updates

Check whether Windows updates are installing on your computers or sitting at "restart required" week after week. Do the same for phones and for the software your team relies on most, such as your browser and your accounting application. If people are regularly clicking "remind me later," that habit is worth addressing. It's one of the most consistent ways a manageable issue quietly becomes an expensive one.

2. Backups

Open your backup tool and look at the last several runs. What you want to see is a list of recent, successful completions rather than a string of errors. Then check when someone last restored a file from the backup. If it has never been tested, you genuinely don't know whether it works. A backup that fails when you need it most is functionally no different from not having one.

3. Who Has Access

Pull up the list of user accounts in Microsoft 365 or Google Workspace and read through it carefully. Every name on that list should belong to someone who currently works for you. Look for people who left, contractors who finished months ago, and shared logins like "office" or "admin" that multiple employees use. Switch off anything you don't need. Access that isn't actively managed is access that's quietly available to the wrong person.

4. Multi-Factor Authentication

Check that MFA is turned on and that it's enabled for everyone, not just the people who configured it at the beginning. Pay closest attention to admin accounts and anyone who handles money or sensitive client information. Research from Microsoft shows MFA blocks more than 99.2% of account compromise attacks. It's one of the highest-return steps a small business can take, and verifying it takes only a few minutes.

5. Devices

Look at what's connected to your systems. If there's a laptop or phone you don't recognize, find out whose it is before assuming it belongs there. While you're at it, check that laptops have encryption enabled and that any phone with company email on it is protected by a passcode or fingerprint lock. This is a review that your IT provider can't fully complete on their end because they don't know which devices belong to your business and which don't.

6. Subscriptions and Licenses

Open your billing page and read through what you're actually paying for. Businesses regularly carry licenses for people who left months ago, or pay for two tools that do essentially the same job. This review is also how you find software someone signed up for without mentioning it to anyone. A quick pass through billing takes about 10 minutes and often saves real money.

Building the Routine

Put this review on the calendar on a fixed day, such as the first Monday of each month, and assign it to the same person every time. That's most likely you or whoever handles the administrative side of your business.

Keep a running note of what you checked and what you found. After a few months, you'll start to see whether the same issue keeps showing up. If it does, it needs a proper fix rather than being cleared out each time. The goal is a short list of findings, not an impromptu repair session. Write down what you find and handle it afterward, so the thirty minutes stay thirty minutes.

What Goes to Your IT Provider

Most of what this check turns up is small: a laptop that needs a restart, a license to cancel, or an account to disable. You can handle those yourself.

Send the rest to your IT provider: backups that keep failing, MFA that won't enable for a specific person, a device nobody can account for, or updates that fail on the same machine every month. Those patterns usually point to something larger behind them, and that's exactly what your provider is equipped to investigate.

What This Check Doesn't Replace

This review is not monitoring. A good IT provider has tools watching your systems around the clock and flagging issues you would never catch from a monthly glance.

What this check covers is the context that those tools can't access: who left the company last month, which subscriptions you actually approved, and whose device is whose. That knowledge lives with you, and it's a meaningful part of keeping a small business secure.

Knowing what to look for is one half of the equation. Knowing how well your systems are being watched is the other. Click here to schedule a quick 26-minute call, and we'll give you a clear look at both.

Article FAQs

How often should a small business run this IT check?

Once a month is enough for most of this list. Backups are worth a more frequent look if losing a day's work would seriously disrupt your operations, since that's the item most likely to fail without any visible sign.

Isn't this something my IT provider should already be handling?

Your IT provider handles monitoring, patching, and fixing. This check covers the part that depends on knowing your business: who left last month, which subscriptions you approved, and which devices belong to your team. That context lives with you, and it's a meaningful part of the picture your provider can't see from their end.
