Network Security Services in Scottsdale: 8 Common Gaps and How to Close Them
Most small business networks weren’t designed. They grew. A firewall went in when the office opened, Wi-Fi came later, and every new printer, camera, and laptop joined the same network. That’s normal, but it leaves gaps. When a business asks us about network security services in Scottsdale, we usually find the same ones.
Here are the eight gaps we check first, and what it takes to close each one. You can work through most of this list with your current IT provider.
Quick Answers
What does network security for a small business include?
Firewall management, network segmentation, secure remote access, patching, account reviews, vulnerability scanning, and monitoring. The goal is to close common entry points and spot trouble early.
Is a firewall enough to protect a small business network?
No. A firewall is one layer. Stolen passwords, unpatched devices, and old accounts can all get past it, so it needs to be paired with MFA, patching, and monitoring.
8 Network Security Gaps We Check First
1. A Firewall Nobody Has Reviewed
Firewalls need firmware updates and a regular review of their rules. Old rules often stay open for systems that are long gone. If nobody can tell you when your firewall was last updated, start there.
2. One Flat Network for Everything
When guest Wi-Fi, security cameras, printers, and your file server all share one network, a compromised device can reach everything else. Segmentation puts them on separate networks, so a problem in one place stays there.
3. Default or Shared Admin Passwords
Routers, switches, and access points often ship with default logins. Shared admin passwords that never change are almost as risky. Each device should have its own password, stored in a password manager.
4. Remote Access Without MFA
Remote desktop and VPN connections are a common way in. Every remote login should require multifactor authentication (MFA). CISA’s guidance for small businesses tells owners to set goals for MFA adoption, patching, and backups.
5. Accounts for People Who Left
Former employees and vendors sometimes keep working logins for months. Offboarding should include disabling accounts, changing shared passwords, and collecting devices.
6. Unpatched and Unsupported Devices
Windows 10 reached end of support in October 2025. Computers still running it without paid extended updates no longer get security fixes. The same goes for firewalls and storage devices past their vendor’s support date.
7. Nobody Watching the Alerts
Firewalls and servers log failed logins and unusual traffic. If no one reviews those alerts, an attacker can work quietly for weeks. Monitoring only helps when someone is responsible for noticing.
8. No Map of the Network
You can’t secure devices you don’t know about. A current list of equipment, settings, and who has admin access is the starting point for every item above.
What Network Security Services Should Cover
| Control | What it does | How often to review |
| Firewall management | Blocks unwanted traffic in and out | Firmware as released; rules at least yearly |
| Network segmentation | Keeps guests, cameras, and servers apart | When devices or offices change |
| MFA on remote access and email | Blocks sign-ins that rely on a stolen password alone | Check coverage quarterly |
| Patching | Closes known security holes | Monthly, plus urgent fixes |
| Vulnerability scanning | Finds weak spots so you can fix them first | Quarterly or after big changes |
| Monitoring | Flags failed logins and unusual traffic | Ongoing |
At Alphatech, these controls are part of our cybersecurity services, and regular vulnerability scanning shows which gaps to fix first.
Why This Matters Beyond IT
Arizona’s data breach law gives a business 45 days to notify affected people after it determines a breach happened. If more than 1,000 people are affected, the attorney general, the Arizona Department of Homeland Security, and the three largest credit reporting agencies must be notified too. Closing common gaps now is far easier than working through that process later.
Ransomware tends to use the same openings. For the bigger picture, we covered how to prepare your business for a ransomware attack.
Where to Start
If you’re not sure where your network stands, a network assessment reviews your firewall, devices, accounts, and documentation and turns the findings into a ranked list. No security program can promise you’ll never have an incident, but closing these eight gaps removes the easiest ways in. Network security is part of the IT services for Scottsdale businesses we provide from our Mesa office. Talk to our team about where to begin.
AI Overview
Network security services for small businesses cover firewall management, network segmentation, MFA on remote access, patching, account reviews, vulnerability scanning, and monitoring. The most common gaps are unreviewed firewalls, flat networks, default passwords, remote access without MFA, old accounts, unsupported devices, unwatched alerts, and missing documentation. Arizona law requires notifying affected individuals within 45 days of determining a breach. Alphatech Computer Solutions provides these services to businesses in Scottsdale and across the East Valley.
Key Takeaways
- Most small business networks grew without a security plan, which leaves predictable gaps.
- A firewall alone doesn’t stop stolen passwords, unpatched devices, or old accounts.
- CISA’s small business guidance puts MFA, patching, and backups at the center.
- Arizona requires breach notices within 45 days of determining a breach.
- A network assessment is the fastest way to see which gaps apply to you.
Frequently Asked Questions
How often should a small business review its network security?
Review firewall rules and admin access at least once a year, check MFA coverage and patch status monthly or quarterly, and check again after big changes like an office move or a new system.
What is network segmentation?
Segmentation splits one network into separate zones, such as guests, cameras, staff computers, and servers. If a device in one zone is compromised, it can’t easily reach the others.
Do Arizona businesses have to report data breaches?
Yes. Under A.R.S. 18-552, a business that determines a breach happened must notify affected individuals within 45 days. Breaches affecting more than 1,000 people also require notice to the attorney general, the Arizona Department of Homeland Security, and the three largest credit reporting agencies. Your attorney can confirm what applies to you.
What does a network security assessment include?
It reviews your firewall, switches, Wi-Fi, servers, workstations, backups, and access practices, then ranks what to fix first. It’s designed to gather what’s needed with little disruption to staff.
