67% of Cyberattacks Start With Identity: What the Sophos 2026 Active Adversary Report Means for Houston SMBs

/in /by

Sophos just released its 2026 Active Adversary Report, and the headline finding should be required reading for every Houston business owner: 67% of all cybersecurity incidents investigated last year were rooted in identity-related attacks. Compromised credentials. Brute-force attacks. Phishing. These are not exotic, nation-state-level threats — they are the everyday attacks targeting businesses just like yours.

For small and mid-sized businesses in Houston, this report is a wake-up call — and a roadmap for where to focus your cybersecurity investment in 2026.

What the Report Found

The Sophos Incident Response and Managed Detection and Response teams analyzed hundreds of real-world attacks. The key findings:

  • 67% of incidents began with an identity attack — stolen credentials, brute-forced passwords, or phishing were the #1 door attackers used to get in
  • RDP (Remote Desktop Protocol) abuse dropped significantly — a win for the security community — but identity-based attacks filled the gap and then some
  • Threat groups are proliferating and specializing — attackers are more organized and move faster than ever once they have a foothold
  • AI is amplifying attacker scale — while AI is not yet replacing human attackers, it is making phishing campaigns more convincing and attacks more frequent

John Shier, Field CISO at Sophos, put it plainly: “The dominance of identity-related root causes for successful initial access has been years in the making. Compromised credentials, brute-force attacks, phishing, and other tactics targeting identity are now the primary means by which attackers gain entry.”

What Houston Businesses Need to Do Right Now

Based on Sophos recommendations and our own experience protecting Houston SMBs, here is what we advise:

  • Enable Multi-Factor Authentication (MFA) everywhere — especially on email, remote access, and any cloud application. This single control would have stopped a significant portion of the 67% of identity-based attacks in the report.
  • Audit your credential hygiene — check for shared passwords, old accounts, and default credentials across your environment. We regularly find these in new client environments.
  • Deploy endpoint detection and response (EDR) — Sophos EDR with managed detection gives you visibility and a rapid response capability that matches the speed modern attackers operate at.
  • Train your staff on phishing — AI-powered phishing is getting harder to spot. Simulated phishing training is no longer optional for any business with more than five employees.
  • Consider Managed Detection and Response (MDR) — if you do not have a security team watching your environment 24/7, an MDR service does it for you at a fraction of the cost of hiring in-house.

You Do Not Need a Large IT Budget to Stay Protected

One of the most common misconceptions we hear from Houston business owners is that enterprise-grade security is out of reach for a 20-person company. It is not. Houston TechSys delivers Sophos endpoint protection, email security, and managed detection capabilities scaled specifically for SMBs — at pricing that makes sense for businesses in Houston’s oil and gas, healthcare, legal, and hospitality sectors.

The 2026 threat landscape is real and it is targeting businesses of every size. The good news is that the right controls, properly deployed, close the majority of attack vectors attackers are actively using today.
