After 15+ years of providing IT support to small businesses across the Santa Clarita Valley, we’ve seen a clear pattern: most cyberattacks succeed not because hackers are brilliant, but because businesses left a door open. The good news is that the most common vulnerabilities are also the most fixable.
Here are the five mistakes we see most often — and what to do about each one.
Mistake #1: Using Weak or Reused Passwords
It sounds basic, but it’s still the #1 way attackers get in. “Password123,” your company name, or the same password across multiple accounts is an open invitation. When one of those accounts gets breached (and data breaches happen constantly — your credentials may already be circulating on the dark web), attackers try the same password everywhere.
The fix: Use a business password manager like 1Password, Bitwarden, or Keeper. Every account gets a unique, complex password that only the manager has to remember. Require this for all employees — not just optional. Setup takes a few hours and costs a few dollars per user per month. It’s one of the highest-ROI security investments a small business can make.
Mistake #2: No Multi-Factor Authentication (MFA)
Even a strong password can be stolen through phishing or a data breach at another service. Multi-factor authentication (MFA) adds a second verification step — usually a code sent to your phone or generated by an app — that stops attackers cold even if they have your password.
The fix: Enable MFA on everything that supports it: email (Microsoft 365, Gmail), cloud storage, banking, accounting software, your website. Microsoft 365 and Google Workspace both include MFA at no extra cost. It takes about 15 minutes to set up per user. We help businesses across Valencia and Santa Clarita configure MFA as part of our managed IT service — it’s one of the first things we do for every new client.
Mistake #3: Employees Who Can’t Spot a Phishing Email
Over 90% of successful cyberattacks start with a phishing email — a message designed to look like it’s from a trusted source (your bank, Microsoft, a vendor, even your boss) that tricks someone into clicking a link or downloading an attachment.
Modern phishing emails are sophisticated. They no longer look like obvious scams from Nigerian princes. They mimic real brands perfectly, create urgency (“Your account will be suspended in 24 hours”), and sometimes appear to come from email addresses of real people in your organization.
The fix: Train your staff to recognize phishing. Look for: unexpected urgency, requests for login credentials or payment information, sender email addresses that don’t match the displayed name, and links that don’t match the company they claim to be from (hover before clicking). Many email security platforms also include simulated phishing tests that send fake phishing emails to your team and report who clicks — an eye-opening exercise for most businesses.
Mistake #4: Skipping Software Updates
When Windows, macOS, or any software pushes an update, there’s often a security patch included that fixes a known vulnerability. Attackers actively scan the internet for systems running unpatched software because those vulnerabilities are publicly documented — it’s essentially a published list of open doors.
We commonly see Santa Clarita businesses running systems that are months or years behind on updates. Some avoid updates because they’ve had a bad experience in the past (a Windows update that broke something). That’s a real concern, but the solution is managed patching — not skipping updates entirely.
The fix: Enable automatic updates for your operating system and major software. For businesses with more complex environments or where “test before deploy” is important, a managed IT provider handles patching in a controlled way that minimizes disruption while keeping systems current.
Mistake #5: No Tested Backup Strategy
Ransomware is the fastest-growing threat to small businesses. Attackers encrypt all your files and demand payment to restore access — often $10,000 to $50,000 or more, with no guarantee they’ll actually decrypt your data. Businesses without a solid backup strategy face an impossible choice: pay the ransom or lose everything.
The businesses that recover fastest from ransomware are the ones with recent, tested backups stored somewhere the ransomware can’t reach — an offline backup, a separate cloud account, or an immutable backup solution.
The fix: Implement the 3-2-1 backup rule: 3 copies of your data, on 2 different types of media, with 1 stored offsite or in the cloud. And critically — test your backups. Many businesses discover their backups don’t actually work only when they need them most. Schedule a quarterly restore test to verify your backup is real and recoverable.
