7 IT Mistakes Houston Businesses Make That Cost Them Dearly

After assessing hundreds of Houston businesses, SpaceTown IT has identified the same costly IT mistakes appearing repeatedly. These mistakes are predictable, preventable, and expensive. If your Houston business is making any of these mistakes, you are carrying avoidable risk that will eventually cost significantly more than the fix would have.

Mistake 1: Assuming Backups Work Without Testing

The most dangerous IT assumption is that backups work because they appear to run. SpaceTown IT encounters silent backup failures in the majority of businesses that have never tested recovery. The backup job runs, logs show success, but the recovery either fails, takes far longer than the RTO, or produces corrupted data. Test backup recovery quarterly — or accept that your backup may not work when you need it.

Mistake 2: No MFA on Email

Email account takeover is the most common Houston business security incident. A stolen email password — whether from phishing, data breach, or credential stuffing — gives attackers complete access to an account without MFA. The cost of enabling MFA on Microsoft 365: zero (included in your subscription). The cost of an email account compromise: $50,000-$500,000 in wire fraud, business email compromise, and breach remediation. There is no justification for a Houston business not running MFA on email in 2025.

Mistake 3: Running End-of-Life Software

Windows 10 reaches end-of-life in October 2025. Windows Server 2012 reached end-of-life in October 2023. Businesses running end-of-life operating systems are running without security patches — giving attackers permanent, unpatched vulnerabilities to exploit. SpaceTown IT regularly encounters Houston businesses running Windows Server 2008 and 2012 on production systems — ticking time bombs waiting to be exploited.

Mistake 4: Shared Admin Accounts

IT accounts with “admin” or “administrator” usernames and shared passwords are common at Houston businesses — and are a critical security vulnerability. Shared accounts cannot be audited (you don’t know which employee did what), cannot have MFA applied effectively, and create privileged access that ransomware operators can steal and use to disable defenses. Every administrator must have a unique, personal privileged account.

Mistakes 5-7: The Remaining Critical Errors

(5) No documented IT asset inventory — you cannot secure what you do not know exists. Unmanaged devices on your network are invisible security risks. (6) Trusting new employees immediately with full access — implement least-privilege access from day one, granting only the access each role requires. (7) Ignoring IT vendor security — every vendor with network access is a potential supply chain attack vector. Review vendor security practices and ensure appropriate access controls.
