  • Why Antivirus Alone Is Not a Security Strategy

    One of the most common things the logic-IT team hears from small-business owners in Georgia is some version of this: “We have antivirus, so we are covered.” It is an understandable assumption. Antivirus has been the face of computer security for decades, and most people install it and move on without a second thought. The problem is that the threat landscape has changed dramatically, and antivirus has not kept pace with it.

    What Antivirus Actually Does

    Antivirus software works by scanning files and processes against a database of known malware signatures. When it finds a match, it blocks or removes the threat. That is genuinely useful, and no one is suggesting you uninstall it. But the keyword is known. Antivirus is reactive by design. It can only catch threats that have already been identified, catalogued, and added to the signature database. Anything newer, anything modified to avoid detection, or anything that does not look like a traditional virus at all will often pass right through.

    The Threats That Actually Show Up

    The logic-IT team works across a wide range of small and mid-sized businesses, and the threats they see regularly are not the obvious viruses from 2009. The real problems look more like this:

    • Compromised credentials. An employee’s username and password get stolen through a phishing site or a data breach at another service. An attacker logs in quietly and looks around. No malware involved, nothing for antivirus to catch.
    • Misconfigured firewalls. A port left open during a setup that never got closed, or a rule that made sense two years ago and no longer does. Antivirus has no visibility into network configuration.
    • Convincing phishing links. Modern phishing emails are well-written and often impersonate vendors or internal staff. One click can hand over credentials or install a payload that looks legitimate to a signature scanner.
    • Slow-moving ransomware. Some ransomware sits inside a network for weeks before it triggers, quietly mapping files and spreading access. By the time it activates, the damage is already staged and waiting.

    None of these require

  • Employee Onboarding and Offboarding Are IT Processes, Not Tasks

    One of the most common requests the logic-IT team receives goes something like this: “We just hired someone, can you set them up with email?” It comes in most weeks, often the day the new hire is supposed to start. The ask sounds simple, but it points to a much larger gap that quietly causes problems for small businesses.

    One Request, Many Moving Parts

    Setting up email is rarely just setting up email. A new employee typically needs access to several systems before they can do their job effectively. Depending on your business, that list might include:

    • A company email account and any shared inboxes they need to see
    • Cloud storage and shared drives with the right folder permissions
    • Business software licenses, whether that is accounting, project management, or industry-specific tools
    • A company device that is configured, secured, and ready to use
    • Multi-factor authentication setup across every platform

    When there is no checklist, each of these items gets remembered at different times, by different people. The new hire spends their first days waiting on access instead of getting productive. That is a frustrating experience for them and a waste of time for whoever is fielding the requests one by one.

    Offboarding Is the Bigger Risk

    If slow onboarding is an inconvenience, poor offboarding is a genuine security risk. When an employee resigns or is let go, access needs to be revoked quickly and completely. Without a defined process, things get missed. Former employees have retained access to company email, shared drives, and cloud tools for weeks after their last day, sometimes without anyone realizing it.

    That kind of exposure can lead to real consequences. A former employee with lingering access to client data, financial records, or internal communications is a liability, regardless of how the departure went. Most of the time it is not malicious, but the risk is the same either way.

    The question worth asking is this: if someone on your team resigned today, what would your first hour look like? Is there a clear list of accounts to disable, devices to collect, and permissions to remove? If the answer is uncertain, that gap is worth closing before you need it.

  • Why Your VPN Keeps Dropping (It’s Not Your Wi-Fi)

    If your VPN drops in the middle of a call and your first instinct is to blame the Wi-Fi, you are not alone. It is one of the most common complaints the logic-IT team hears from small businesses across Georgia. And in most cases, the router is completely innocent.

    Why Wi-Fi Gets the Blame

    Wi-Fi is visible and easy to point at. You can see the signal bars, you can reboot the router, and it feels like doing something. But a VPN connection lives at a different layer of your network. It depends on software versions, authentication handshakes, and server-side configuration, none of which a new router will touch. Upgrading your hardware before diagnosing the real problem just adds cost without solving anything.

    The Three Things That Actually Cause VPN Drops

    • Client and server version mismatch. VPN software on your laptop needs to match, or at least be compatible with, the version running on the server. When they fall out of sync after an update on either end, the connection becomes unstable. This is one of the first things logic-IT checks, and it clears a surprising number of cases on its own.
    • Split-tunnel settings configured incorrectly. Split tunneling controls which traffic goes through the VPN and which goes directly to the internet. When it is set up wrong, your device can lose its route mid-session, especially during video calls that pull from multiple sources at once. Reviewing and correcting those rules often stops the drops immediately.
    • Authentication timeout set too short. VPN sessions require periodic re-authentication to stay secure. If the timeout window is shorter than a typical meeting or work session, the connection will silently expire and drop while you are still actively using it. Adjusting that value to something practical, without creating a security gap, is a straightforward fix that makes a real difference.

    What to Do When the VPN Drops Mid-Call

    In the moment, the fastest recovery is usually to disconnect fully, wait ten seconds, and reconnect rather than letting the client try to resume a broken session. That gets you back faster than waiting for an automatic retry.

    For a permanent fix, someone needs to pull the VPN logs

  • Why a Running Backup Is Not the Same as a Working One

    Most small businesses have some form of backup running. A scheduled job kicks off each night, the software shows a green checkmark, and the owner moves on assuming the data is protected. That assumption is reasonable, but it is not the same as verified.

    The Gap Between “Backed Up” and “Recoverable”

    Backup software can report success while quietly producing files that will not open, archives that are partially corrupt, or jobs that silently fail after a software update. The tool is running. The data may not actually be there in a usable form. You will not find out either way until someone tries to restore something, and the worst time to discover a problem is when a real incident is already in progress.

    This gap is common. It is not a sign that a business cut corners. Backup tools are generally set up once and then trusted indefinitely, and most of them do not make it obvious when something has quietly gone wrong.

    What a Real Test Actually Looks Like

    A restore test does not have to be complicated. The basic version is straightforward:

    • Pick a specific file or folder from your backup, something with a known, readable format like a document or spreadsheet.
    • Pull it from the backup through the normal restore process, not by copying the original.
    • Open it and confirm the contents look correct.

    If the restore completes and the file opens cleanly, that is a good sign. If the tool throws an error, the file is blank, or the contents are garbled, you have found a real problem. Finding it during a routine test means you have time to fix it. Finding it after a ransomware attack or a server failure means you do not.

    A more thorough test goes further, covering full system restores and checking that recovery time meets what the business actually needs. But even the simple file-level test described above is far better than no test at all.

    Why Testing Needs to Happen on a Schedule

    A backup that tested fine six months ago is not guaranteed to work today. Software updates, storage changes, credential expirations, and configuration drift can all break a backup job without any visible alert. A one-time test gives you a snapshot. Scheduled testing gives you ongoing confidence.

  • The quiet Microsoft change that will catch a lot of teams off guard

    Microsoft has quietly announced a change to how people sign in to Microsoft 365, and it is going to surprise a lot of businesses.

    What is changing

    Microsoft is retiring the text-message and phone-call codes that many people use as their second step at login. In their place, Microsoft is making passkeys the default. A passkey is a login tied to your device or a secure key instead of a code you type, and it is far harder for an attacker to steal or trick out of you.

    The two dates that matter

    On September 1, 2026, passkeys become the default and anyone still using SMS or voice codes will start getting prompted to set one up. Those early prompts can be postponed. On February 1, 2027, Microsoft stops providing SMS and voice codes altogether. After that, any user whose only login method is a text or a call will be required to register a passkey before they can get in, and there is no way to opt out.

    Who feels this most

    Any organization where staff still confirm logins with a texted code. If that is how most of your team signs in today, February is a hard wall, not a suggestion. This applies to standard Microsoft 365 business tenants.

    What to do now

    You do not need to wait. First, identify who is still on SMS or voice. Then move those people to a passkey, the Microsoft Authenticator app, or Windows Hello over the next few months, well ahead of the deadline. Moving to passkeys costs nothing extra and is a genuine security improvement. If you have a specific regulatory reason you must keep text codes, Microsoft will offer a paid third-party option, but for almost everyone passkeys are the better path.

    Handled early, this is a quiet upgrade your team barely notices. Left to the last minute, it becomes a stack of locked-out users and support calls. Is your organization and support team ready?

  • Why Emailing File Attachments Creates Risk for Your Business

    A question logic-IT hears often from small-business owners goes something like this: “Can I just email this file to our vendor, or is that a problem?” It is a fair question, and the honest answer is that the file itself is rarely the issue. The problem is how the file travels.

    What Actually Happens When You Send an Attachment

    When you attach a file to a standard email and hit send, you give up control of that file immediately. A few things can go wrong from that point forward.

    • Interception in transit. Email is not a sealed channel. Attachments can be read or copied if the connection is not properly encrypted, and not every server along the route guarantees that.
    • Uncontrolled forwarding. Once your vendor receives the file, they can forward it to anyone. You have no visibility into where it goes next, and no way to stop it.
    • Blocked delivery. Many mail servers flag attachments based on file type or size and quietly hold them in a queue. Your vendor may never receive the file, and you may never get a bounce message telling you so.

    None of these problems require a sophisticated attacker. They are ordinary, everyday risks that come with the attachment habit most businesses have used for years.

    A Better Approach Most Businesses Already Have Access To

    If your business uses Microsoft 365, you already have a more controlled way to share files with vendors and clients. SharePoint and OneDrive sharing links let you send access to a file rather than the file itself. That distinction matters more than it sounds.

    With a sharing link, you decide exactly who can open it, whether they can edit or only view the content, and how long the access lasts. When the job is done, you revoke the link. The file stays in one place, under your control, and access disappears the moment you remove it.

    Compare that to an attachment. Once it lands in someone’s inbox, it lives there indefinitely. You cannot unsend it, expire it, or track where it goes. The access you granted on Monday is still active years later, even if the vendor relationship ended on Tuesday.

    What This Looks Like in Practice

    The

  • What to Do in the First 5 Minutes of a Cyber Incident

    “If we got hacked, we’d know right away.” The logic-IT team hears this regularly from small-business owners. The reality is that many breaches go unnoticed for days or weeks, and when something suspicious does surface, the instinct to start clicking around and investigating on your own is one of the most damaging things you can do.

    The first five minutes of a suspected cyber incident shape everything that comes after. Getting those minutes right can mean the difference between a contained problem and a full recovery nightmare.

    Why the First Five Minutes Are So Critical

    When an attacker is active on your network, every second of continued connection gives them more access. They can move from one device to others, pull data, plant additional tools, or lock files before anyone realizes what is happening. At the same time, the actions taken by well-meaning employees in those early moments often destroy the evidence an IT team needs to understand what happened and how far it spread.

    Panic is normal. Acting on that panic without a plan is where things go wrong.

    The Right Steps, in Order

    • Disconnect the device from the network first. Unplug the ethernet cable or turn off Wi-Fi on the affected machine. This cuts the attacker’s access without disturbing what is on the device itself.
    • Do not power the device off. This is the most common mistake. Shutting down a computer can wipe the temporary memory that holds critical forensic information, including what processes were running, what connections were active, and what the attacker was doing. Your IT provider needs that data.
    • Do not log in, click through files, or try to find the problem yourself. Every action taken on a compromised machine can overwrite evidence or trigger additional malicious activity.
    • Call your IT provider before touching anything else. Give them a clear description of what you saw, when you saw it, and what, if anything, was done before the call. That information helps them move faster.

    What logic-IT Sees Most Often

    A significant portion of incident response work involves undoing actions taken before the call came in. An employee notices something strange, tries to investigate, runs a scan, or rest

  • Why New Employees Get Locked Out of Microsoft 365

    A new employee sits down on their first week, tries to check their company email, and gets an access denied message. No work gets done until someone fixes it. This is more common than most small businesses expect, and the cause is usually a simple setup detail that got skipped during onboarding.

    What Actually Happened

    A retail business added a new staff member and needed a Microsoft 365 account set up. The account was created and the employee was sent to Office.com with a temporary password. They logged in once, and then lost access shortly after.

    The culprit was a forced password change on first login. Microsoft 365 accounts are often configured to require the user to create a new password the first time they sign in. If the employee does not complete that full process, or forgets the new password they set, the account becomes inaccessible. A credential reset got the employee back in, but it cost time and caused unnecessary frustration during an already busy onboarding period.

    Why This Trips People Up

    The forced password change setting exists for a good reason. Temporary passwords should not stay active forever. But the handoff between account creation and the employee actually completing setup is where things fall apart. A few specific situations cause most of these lockouts:

    • The employee logs in once but does not finish setting a permanent password. The session ends, and the temporary password no longer works.
    • The employee sets a new password but does not write it down or save it. Three weeks later, they have forgotten it entirely.
    • No one walks the employee through the setup. They are just handed a link and a temporary password and expected to figure it out.
    • Multi-factor authentication is required but not configured. The account prompts for a second verification method that was never set up, blocking access before it even starts.

    How to Prevent It

    A reliable onboarding process for company email does not need to be complicated. It just needs to be consistent. A few practices that help:

    • Walk new employees through first login in real time, either in person or over a quick screen share, so the password change is completed correctly

  • Why Free Email Hurts Your Business Deliverability

    If your business sends email from a Gmail, Yahoo, or similar free address, some of those messages are landing in spam folders right now. The people receiving them may never tell you. They may not even realize it themselves. That quiet filtering is one of the more common problems the logic-IT team runs into when working with small businesses in Georgia, and it is almost always invisible until a deal falls through or a vendor stops responding.

    Why Receiving Servers Flag Free Email Addresses

    Every email server that receives a message runs a quick trust check on the sender. Part of that check looks at the sending domain. A message from yourbusiness@gmail.com carries no proof that it belongs to an actual business. It looks identical to millions of personal accounts, many of which are used for spam. Receiving servers see that pattern and treat the message with suspicion, sometimes routing it to junk automatically.

    A custom domain address like you@yourbusiness.com signals something different. It says a real organization registered a domain, set up mail hosting, and configured the technical records that prove ownership. That context matters to spam filters, and it matters to the people reading your messages.

    The Authentication Records That Actually Do the Work

    A custom domain alone is not enough. The domain also needs proper authentication records published in its DNS settings. These three records do most of the work:

    • SPF tells receiving servers which mail servers are allowed to send on behalf of your domain.
    • DKIM adds a cryptographic signature to outgoing messages so the recipient can verify the message was not altered in transit.
    • DMARC gives receiving servers instructions on what to do if SPF or DKIM checks fail, and it sends reports back to you so you can see if someone is spoofing your domain.

    Without these records, even a custom domain address can end up in spam. With them properly configured, your messages have a much better chance of reaching the inbox.

    What the Setup Actually Costs

    This is where most small-business owners are surprised. A business email address on your own domain typically runs under ten dollars a month through providers like Google Workspace or Microsoft 365. The domain itself,

  • How to Spot a Fake Invoice or Login Page Before You Click

    A staff member gets an email from what looks like a familiar vendor. The logo is right, the tone is professional, and there is a “Pay Now” button front and center. It feels routine. Then someone flags it, and suddenly the whole team is asking the same question: how did that almost work?

    This scenario comes up regularly for the logic-IT team. Phishing emails and fake login pages are not crude anymore. They are built to pass a quick glance, and they often do. The difference between a costly mistake and a near miss usually comes down to knowing exactly where to look.

    The Details That Give Fakes Away

    Attackers put real effort into making fraudulent emails look legitimate, but they almost always leave traces. The most common tells include:

    • A sender domain with one transposed letter. The display name may say your vendor perfectly, but the actual sending address might read “invoi ces@acm e-supp1ies.com” instead of the real domain. One character off is all it takes.
    • A payment button that routes somewhere unexpected. Hover over any “Pay Now” or “Click Here” link before you touch it. If the URL does not clearly match the vendor’s actual domain, treat it as suspicious.
    • A login page without HTTPS. Any page asking for credentials should show a padlock and “https” in the address bar. A page that loads over plain HTTP is a hard stop.
    • Urgency without a paper trail. Real vendors rarely send a first contact as an urgent payment demand. If there is no prior invoice, purchase order, or conversation to match it against, that pressure is a tactic, not a deadline.

    The One Habit That Stops Most Attacks

    Spotting visual clues helps, but the single most reliable defense is verifying through a separate channel you already trust. That means picking up the phone and calling the vendor using a number from a previous paper statement, your own saved contacts, or the vendor’s official website. Do not use any contact information inside the suspicious email itself. An attacker who sent the email also controls whatever phone number or reply address appears in it.

    This one step, calling to confirm before acting on any unexpected financial request,
