Cybersecurity is no longer a problem exclusive to large enterprises. Small and mid-sized businesses (SMBs) are increasingly targeted by cybercriminals because they often have fewer resources to defend against sophisticated attacks. Being proactive about cybersecurity can mean the difference between thriving and struggling to recover from a serious breach. Here are the top ten cybersecurity threats your business faces in 2025 and tips to protect yourself.
Ransomware attacks
Ransomware remains one of the most damaging threats. Cybercriminals encrypt your business data and demand a ransom for its release. SMBs are targeted because they may lack robust backup and recovery systems. Preventative measures like regular data backups and strong endpoint security are critical.
Phishing emails
Phishing attacks trick employees into providing sensitive information, such as login credentials. These attacks have evolved to include highly personalized emails that are harder to recognize as scams. Employee training and email filtering tools can reduce the likelihood of a successful phishing attack.
Credential theft
Cybercriminals are constantly searching for login credentials to access business systems. They often steal these through phishing, malware, or by exploiting weak passwords. Implementing multi-factor authentication (MFA) can significantly improve your security posture by requiring additional verification beyond a password.
Insider threats
Insider threats—whether malicious or accidental—pose a serious challenge for small businesses. Employees, contractors, or even former staff may misuse access to your systems. Limiting access to sensitive data and monitoring user activity can reduce the chances of insider incidents or account compromises.
IoT device exploits
As more businesses adopt Internet of Things (IoT) devices like smart cameras, thermostats, and inventory trackers, these devices have become a growing attack surface. Many IoT devices have weak security protocols, making them vulnerable. Ensure that all devices are updated regularly and segregated from critical business networks.
Supply chain attacks
Cybercriminals are increasingly targeting SMBs by compromising third-party vendors or software suppliers. This can result in malware infections and data breaches without any direct attack on your business. Vetting vendors, limiting their access to your systems, and monitoring for suspicious activity can help defend against supply chain attacks.
Zero-day vulnerabilities
Zero-day vulnerabilities are newly discovered flaws in software that hackers can exploit before developers issue a fix. These vulnerabilities are difficult to prevent entirely but can be mitigated by keeping your software up to date and using security tools that detect abnormal behavior.
Distributed Denial-of-Service (DDoS) attacks
DDoS attacks flood a business’s network or website with traffic, causing service disruptions. While these attacks are often used to target large companies, SMBs can also be affected. Implementing DDoS protection services can prevent attacks from overwhelming your network and keeping you from doing business.
Social engineering scams
Social engineering involves manipulating people into revealing confidential information or performing harmful actions. Attackers may impersonate trusted contacts or authority figures to gain access to your systems. Training employees to recognize these tactics and verifying unusual requests can reduce risk.
How to protect your business
Understanding these threats is only the first step. Here are some actionable strategies to help secure your business:
Invest in Employee Training: Regularly educate employees on cybersecurity best practices and how to recognize threats.
Use Multi-Factor Authentication (MFA): Adding an extra layer of security to logins helps prevent unauthorized access.
Regular Backups: Ensure you have automated backups of critical data and test your recovery procedures.
Implement Network Monitoring: Continuous monitoring of your network can detect suspicious activity early, allowing you to respond quickly to potential threats.
Partner with a Managed Service Provider (MSP): A trusted MSP can monitor your systems, provide threat intelligence, and ensure security updates are applied consistently.
Cybersecurity doesn’t have to be overwhelming. By addressing these top threats and taking a proactive approach, your business can stay one step ahead of cybercriminals and safeguard your operations in 2025.
