Best Cybersecurity Practices for US SMEs

Why Cybersecurity is a Critical Priority for US SMEs Today

Small and medium-sized enterprises (SMEs) in the US are facing unprecedented cyber threats in 2025. Cybercriminals are targeting these businesses more than ever because many lack the resources and expertise to defend themselves effectively. The average cost of a cyberattack on SMEs can reach over $120,000, and nearly 60 percent of small businesses that suffer a significant breach close permanently within six months. This alarming reality makes robust cybersecurity practices a non-negotiable for SMEs looking to survive and thrive in today's digital economy.

Essential Cybersecurity Practices for US SMEs

Keep Software and Systems Updated Regularly

Running outdated software leaves your business open to attacks. Hackers often exploit known vulnerabilities in old versions of operating systems, browsers, or business applications. Regular and timely updates patch these security holes and protect your network from intrusions.

• Designate staff members to manage software updates or automate the process using trusted patch management tools. This reduces human error and ensures systems remain secure without interrupting business hours.
• Prioritize critical systems like operating systems, firewalls, antivirus software, and productivity suites such as email clients and browsers.
• Replace outdated or unsupported software that no longer receives security updates, to eliminate hidden weaknesses in your infrastructure.
• Conduct scheduled quarterly security audits to spot any neglected patches or misconfigurations before attackers exploit them.
• Use centralized update management tools to track patching status across all company devices, providing compliance evidence and reducing risks.

Why it matters: Updating software is your most basic yet powerful defense. Every patch closes a known door hackers might use, dramatically reducing your exposure to ransomware and other malware threats that are on the rise.

Enforce Strong Password and Access Control Policies

Weak passwords continue to be a major vulnerability exploited by cybercriminals. SMEs must adopt comprehensive password policies combined with layered access controls to keep data safe.

• Require staff to create complex passwords that mix letters, numbers, and symbols, and prohibit password reuse across systems.
• Provide and mandate the use of password managers like Bitwarden or LastPass to help store and generate strong credentials securely.
• Implement multi-factor authentication (MFA) on all critical platforms and remote access solutions to add an extra layer of protection beyond just passwords.
• Regularly review user access permissions to ensure employees only have rights necessary for their roles, and promptly revoke access for former employees.
• Limit administrative privileges strictly to IT or cybersecurity personnel to minimize the attack surface for privilege escalation.

Why it matters: Attackers often gain entry through weak or stolen credentials. Strong password policies and MFA close this gap and prevent unauthorized lateral movement within your network once compromised.

Backup Data Frequently and Test Your Recovery Plan

SMEs today cannot afford to lose data due to ransomware, accidental deletion, or hardware failure. Implementing a disciplined backup strategy will protect core business information and ensure quick recovery.

• Follow the 3-2-1 backup rule: keep three copies of your data, on two different local devices, with one copy securely stored offsite or in the cloud.
• Automate daily backups to reduce human error and maintain an up-to-date version of your data.
• Encrypt backups to prevent attackers from accessing critical data if backup media is stolen or compromised.
• Schedule monthly recovery drills to test backup restorations and confirm data integrity, avoiding surprises during actual incidents.
• Train employees on regular data saving protocols and integrate backup tools seamlessly into daily workflows.

Why it matters: Regular backups eliminate the need to pay ransoms and minimize downtime from cyberattacks or operational errors, protecting your company's revenue and reputation.

Educate Employees on Cybersecurity Awareness

Human error is responsible for the majority of cyber incidents. Employees who recognize phishing attempts, avoid suspicious links, and follow security protocols are an SME’s first and best defense.

• Conduct ongoing training sessions including real-world examples and simulated phishing exercises to keep staff alert and informed.
• Clearly communicate security policies and update them frequently based on emerging threats to ensure relevancy.
• Empower employees to report suspicious emails, strange device behavior, or potential breaches immediately without fear of repercussions.
• Promote a security-first culture by tying awareness programs to performance metrics and leadership support.
• Regularly refresh training materials and involvement through newsletters, posters, or quick reminder videos.

Why it matters: A well-trained team drastically reduces vulnerability to phishing scams, social engineering, and accidental data leaks, which remain the easiest methods for attackers to breach small businesses.

Secure Your Network with Firewalls, VPNs, and Endpoint Protection

Effective network protection is essential to filter malicious traffic and secure remote connections, especially with the rise of remote work.

• Deploy hardware and software firewalls configured with strict rules to block unauthorized access attempts.
• Use Virtual Private Networks (VPNs) to encrypt remote workers’ connections, ensuring data flows safely over the public internet.
• Install reputable antivirus and endpoint detection and response (EDR) tools on all employee devices to monitor, detect, and remove malware quickly.
• Segment networks to isolate sensitive data from the rest of the company’s traffic, limiting the damage of any breaches.
• Keep all network devices up to date and conduct regular penetration tests to uncover and fix vulnerabilities.

Why it matters: Network security tools act like a digital fortress, blocking most attacks before they reach employee devices or business-critical systems, and securing remote access in an era of hybrid work.
