Small and medium-sized businesses (SMBs) have increasingly become prime targets. In recent years, nearly half of all global cyberattacks have focused on SMBs, and many of those affected struggle to stay in business afterward. Ransomware campaigns and phishing scams are surging, often aimed at organizations with fewer than 1,000 employees. These attacks can lead to major disruptions, data breaches, and devastating financial consequences.
Three recent incidents demonstrate the trend: a major insurer experienced a network intrusion exposing Social Security numbers and claims data; a large retail cooperative had to shut down systems due to a cyberattack; and several well-known consumer brands faced data leaks and operational chaos due to external intrusions.
These examples highlight how no organization is too small or too niche to be targeted—and how essential cybersecurity has become for SMBs.
Key Vulnerabilities Exploited by Attackers
Ransomware-as-a-Service (RaaS) is a popular tactic used by attackers. It relies on compromised credentials, outdated software, and vulnerable remote access tools to infiltrate business networks. Once inside, attackers encrypt data or steal it for ransom.
Another rising threat is phishing and business email compromise (BEC). With the help of artificial intelligence, scammers are crafting highly realistic phishing emails and even deepfake messages that trick employees into revealing sensitive information.
Supply-chain attacks are also escalating, where hackers compromise a third-party service or software vendor to gain access to multiple downstream businesses at once. One such incident exposed tens of millions of records across thousands of organizations.
What SMBs Can Do: A 5‑Point Defense Plan
-
Strengthen Authentication & Access Controls
Use multi-factor authentication (MFA) for all users, enforce strong password policies, and limit administrative privileges. Privileged access should be monitored and managed with proper tools. -
Keep Systems Updated & Secure Remote Access
Ensure all software—including operating systems, VPNs, and any remote desktop tools—are up to date. Patching known vulnerabilities quickly is one of the most effective defenses. -
Train Employees on Cyber Hygiene
Provide ongoing cybersecurity awareness training focused on recognizing phishing attempts, suspicious attachments, and deceptive messages. Employees are the first line of defense. -
Implement Reliable Backups & Incident Response Plans
Regularly back up important data and store it offline or in secure cloud environments. Have a clear, documented incident response plan to react quickly in case of a breach. -
Use Security Tools & Consider Insurance
Deploy endpoint protection, firewalls, and modern threat detection tools. These help monitor activity and detect anomalies before damage is done. Cyber insurance can also offer protection and resources during and after an attack.
Final Word: Cyber Resilience is Key
With cyberattacks growing more frequent and sophisticated, SMBs must focus on resilience—minimizing damage, recovering quickly, and maintaining customer trust. While no business is completely immune, a layered defense strategy and proactive mindset can significantly reduce risk and make all the difference when facing a potential threat.
Call to Action for SMB Owners
Now is the time for SMBs to take cybersecurity seriously. Review your current security posture, consult experts or managed service providers if needed, and make cyber defense a routine part of your operations. The cost of prevention is far lower than the impact of a successful attack.
