Cybersecurity Best Practices for
Medium-Sized Businesses
- November 11, 2025
As a medium-sized business, 101 IT understands that your organization is growing, and with growth comes more exposure to cyber risks. Unlike small businesses, medium-sized companies often have more complex systems, multiple users, and larger amounts of sensitive data. This makes having a strong cybersecurity strategy essential.
Assessing Your Current Security Posture, Employee Training and Awareness
The first step is to assess your current security posture. Identify your critical assets, sensitive information, and potential vulnerabilities in your systems. Conducting a thorough risk assessment helps pinpoint areas where your business might be exposed. For example, are your financial records, customer data, or intellectual property adequately protected? Once you know your vulnerabilities, you can prioritize measures to address them. Regular audits and reviews of your IT infrastructure are key, especially as your business grows and adds new systems or employees.
Next, focus on employee training and awareness. Even the best technical security systems can fail if staff are not educated about common threats such as phishing emails, social engineering, and weak password practices. Medium-sized businesses often have multiple departments and teams, each with access to sensitive data. Creating a culture of cybersecurity awareness ensures every employee understands their role in protecting the organization. Consider regular training sessions, simulated phishing tests, and clear, documented policies for password management, device use, and email handling. Employees should know exactly how to report suspicious activity and understand the potential consequences of a security breach.
Network Security and Access Controls
Another critical area is network security. Implementing firewalls, antivirus software, and intrusion detection systems protects your infrastructure from external attacks. Ensure that all devices are updated regularly and that software patches are applied promptly. Medium-sized businesses often have multiple access points, remote workers, and cloud services, which can create gaps if not properly secured. Establishing strict access controls, using multi-factor authentication, and monitoring unusual activity on your network can prevent unauthorized access. Encrypting sensitive data in transit and at rest is also a best practice that adds another layer of protection.
Data Backup, Recovery, and Endpoint Security
Data backup, recovery, and device security are vital components of a strong cybersecurity strategy. Cyberattacks such as ransomware can lock your files, making them inaccessible until a ransom is paid. A robust backup strategy ensures you can recover quickly from incidents without losing critical information. Medium-sized businesses should implement automated backups stored securely offsite or in the cloud and regularly test these backups to confirm they can be restored efficiently.
At the same time, securing endpoints is essential. Employees often use laptops, mobile devices, and tablets that may contain sensitive information. Protecting these devices with encryption, anti-malware software, and remote wipe capabilities helps safeguard your data if devices are lost or stolen. Medium-sized businesses should also enforce strict policies for personal devices used for work and ensure that any third-party software installed on company devices meets security standards. Combining reliable backups with strong endpoint security provides a solid defense against data loss and cyber threats.
Managing Third-Party Risks
Large organizations often work with multiple vendors, partners, and contractors who may have access to critical systems and sensitive information. While these partnerships are necessary for business operations, they also introduce potential security risks. Ensuring that all third-party partners follow strict security protocols is essential to maintaining a strong cybersecurity posture.
Contracts with vendors should clearly define cybersecurity expectations, including requirements for data handling, access controls, encryption, and incident reporting. It is also important to include clauses specifying consequences if these standards are not met. Large businesses should regularly review and audit third-party practices to verify compliance and identify any vulnerabilities.
Beyond formal contracts, building strong communication and collaboration with vendors can reduce risks. Encourage partners to participate in cybersecurity training and share updates on new threats or security improvements. Consider requiring third-party security certifications when possible to ensure that partners meet industry standards.
By proactively managing third-party risks, large businesses can prevent breaches that originate outside the organization, protect sensitive information, and maintain trust with clients, employees, and partners. Third-party risk management is not a one-time task but an ongoing process that must adapt as vendors, technologies, and threats evolve.
Large businesses face complex cybersecurity challenges, but with the right strategy, they can protect sensitive information, maintain compliance, and ensure business continuity. From risk assessments and employee training to network security, endpoint management, and third-party oversight, a layered approach is essential.
