Houston businesses are under attack. In 2024, the FBI's Houston field office reported a 43% increase in cybercrime targeting small and mid-sized businesses in the Greater Houston area. From ransomware hitting energy sector suppliers to phishing attacks targeting law firms in the Galleria, no industry is immune. The good news? Most successful cyberattacks exploit preventable vulnerabilities. This checklist covers the 12 most critical security controls every Houston business should have in place before the end of Q2 2025.
1. Multi-Factor Authentication (MFA) on Everything
If your team can log into Microsoft 365, your VPN, or your banking portal with just a password, you're one phishing email away from a breach. Enable MFA on every business application — especially email, cloud storage, and financial systems. Microsoft reports that MFA blocks 99.9% of automated account compromise attacks. This is the single highest-ROI security control you can implement today, and it costs nothing if you're already on Microsoft 365 or Google Workspace.
2. Endpoint Detection & Response (EDR) — Not Just Antivirus
Traditional antivirus is dead. Modern threats use fileless malware, living-off-the-land techniques, and zero-day exploits that signature-based antivirus simply cannot catch. Every Houston business needs Endpoint Detection & Response (EDR) software on every device — laptops, desktops, and servers. Solutions like CrowdStrike Falcon, SentinelOne, or Microsoft Defender for Business provide behavioral analysis that catches threats antivirus misses. If your IT provider is still selling you Norton or McAfee as your primary protection, it's time for a conversation.
3. Email Security & Anti-Phishing Filters
Over 90% of cyberattacks start with a phishing email. Microsoft 365's built-in spam filter is not enough. You need a dedicated email security layer — Microsoft Defender for Office 365 Plan 2, Proofpoint, or Mimecast — that provides link sandboxing, attachment detonation, and impersonation protection. For Houston businesses in industries like healthcare, legal, and finance, this is non-negotiable. Business Email Compromise (BEC) attacks cost Houston businesses millions annually.
4. Automated, Tested Backups Following the 3-2-1 Rule
The 3-2-1 backup rule: 3 copies of your data, on 2 different media types, with 1 copy offsite (cloud). But here's what most businesses miss — backups are worthless if they've never been tested. We've seen Houston companies hit by ransomware discover their backups were corrupted or incomplete. Test your restore process quarterly. Your backup is only as good as your last successful restore test.
5. Security Awareness Training for Every Employee
Your employees are your biggest security risk — and your best defense. Monthly security awareness training using platforms like KnowBe4 or Proofpoint Security Awareness Training dramatically reduces phishing click rates. Simulated phishing campaigns keep employees sharp. For Houston businesses with remote or hybrid teams, this is especially critical since employees working from home face more social engineering attempts.
6. Patch Management — Every Device, Every Month
Unpatched software is the #1 entry point for ransomware. The WannaCry ransomware attack that devastated businesses worldwide exploited a Windows vulnerability that had been patched two months earlier. Every device in your Houston business — Windows PCs, Macs, servers, network equipment — needs automated patch management. Critical patches should be deployed within 72 hours of release.
Key Takeaways
Cybersecurity isn't a one-time project — it's an ongoing program. The Houston businesses that get breached aren't necessarily the ones with the worst security; they're often the ones that stopped paying attention.
