10 Major Cybersecurity Threats for Businesses

Managing cybersecurity threats isn’t just for large businesses. Many people believe small businesses face less cybersecurity risk. However, this is a myth, and SMBs still need to protect themselves against major security threats. In 2018, 62% of businesses experienced phishing and social engineering attacks. Of all security breaches, 43% of victims are small businesses, and smaller organizations also have the highest rate of targeted malicious emails.

To protect your business from cybersecurity problems, the best thing that you can do is take preventative measures. It’s much better to prevent cyberattacks than to react to them after they occur. By the time you act against an attack, the damage may already be done. Choosing a preventative, proactive approach can help you stop attacks before they happen.

Major Cybersecurity Threats for Businesses

The major cybersecurity threats for businesses include phishing, malware, ransomware, DDoS attacks, weak passwords, software vulnerabilities, insider threats, unsecured personal devices (BYOD), and inadequate employee security awareness. These threats can lead to data breaches, unauthorized access, operational downtime, and financial damage. Businesses can reduce their exposure by implementing multi-factor authentication (MFA), applying security patches promptly, providing employee awareness training, securing endpoints, maintaining reliable backups, and using continuous security monitoring to detect and respond to suspicious activity.

1. Malware

Malware is a blanket term that includes several different types of cybersecurity threats. It includes threats such as Trojans and viruses that can disrupt businesses and their IT systems. It can give hackers access to systems or destroy data that can’t be recovered.

2. Phishing

Phishing attacks are a very common way hackers exploit businesses. Phishing is when an attacker pretends to be a trusted contact to convince someone to open an email, click a link, or download a malicious file. Phishing attacks have become more sophisticated and can be tough to avoid.

3. Viruses

As a type of malware, viruses can cause damage to your business. A virus is a type of computer program that can modify other programs by inserting its own code. It can create corrupt files or try to steal your business data. Removing a virus isn’t always easy, so it’s best to protect against them.

4. Ransomware

As the name suggests, ransomware is designed to hold your business to ransom. It involves encrypting company data so it can’t be accessed, with a threat to only hand back access of the data if a ransom is paid. This type of threat has become more frequent and is designed to cause panic.

5. DDoS

A DDoS (distributed denial-of-service) attack floods your web server with requests to overwhelm it. Some people think that this type of attack is a thing of the past, but it is still more common than you might realize. In fact, these attacks have become more frequent in recent years.

6. BYOD Problems

Businesses sometimes implement Bring Your Own Device policies to let employees use their own devices, which helps the business save money. However, because the company does not fully control these devices, it can pose security risks. The best approach is to implement BYOD policies that require antivirus and firewall protection.

7. App Vulnerabilities

Businesses might use many different apps, which can provide many functions. However, they can also have security vulnerabilities, and many access personal data you likely don’t want them to access. This issue can be worse when employees use personal devices, making it even more important to control them.

8. Weak Passwords

Another issue employees can cause is using weak passwords. People often choose passwords that are easy to guess and therefore easy to hack. To protect your business, require employees to use strong passwords and enable two-factor authentication to add an extra layer of security.

9. Lack of Employee Awareness

Overall, employee awareness of cybersecurity issues is essential to a business’s cybersecurity. Employees who lack knowledge of critical issues can threaten the company by leaving it vulnerable. Employees should receive cybersecurity training and learn what they can do to help keep the business secure.

10. Patch Management

Good IT management is a must for businesses of all sizes. One reason is the need to keep IT systems updated and install patches quickly to fix vulnerabilities. Patching is a key way to protect vulnerable systems and strengthen security. Protect your business in 2020 by understanding major cybersecurity threats and how to avoid them.

How Can Businesses Prevent and Reduce Cybersecurity Risks?

Businesses can prevent and reduce cybersecurity risks by identifying weaknesses, implementing appropriate security controls, monitoring IT environments, and regularly reviewing their security practices. Rather than relying on a single security solution, organizations should adopt a layered approach that protects their networks, endpoints, applications, user accounts, and sensitive business data. The following practices can help businesses strengthen their cybersecurity posture:

• Conduct regular risk assessments: Identify critical systems, sensitive data, potential vulnerabilities, and security gaps. Prioritize remediation based on incident likelihood and potential business impact.
• Implement layered security controls: Combine endpoint protection, network security, access controls, email security, and other appropriate safeguards to reduce exposure across the IT environment.
• Apply least-privilege access: Give employees and third parties only the permissions they need to do their jobs. Review access rights regularly and remove unnecessary access promptly.
• Monitor IT systems continuously: Review security events, investigate unusual network activity, and establish clear escalation procedures for suspicious behavior.
• Maintain an incident response plan: Define responsibilities, communication procedures, containment steps, and recovery priorities before an incident occurs.
• Review security controls regularly: Reassess risks after infrastructure changes, new application deployments, changes in business operations, or significant security incidents.

Cybersecurity risk reduction is an ongoing process, not a one-time implementation. Businesses should regularly evaluate whether their existing controls are effective and address gaps as their IT environments evolve. Organizations that need more visibility into suspicious activity can explore ExterNetworks Cyber Threat Monitoring to see how external monitoring support can complement their internal security capabilities.

How Do Cybersecurity Threats Affect Businesses?

Cybersecurity threats can affect businesses far beyond their IT infrastructure. A security incident may interrupt daily operations, expose confidential information, increase recovery costs, and damage relationships with customers, partners, and suppliers. The impact depends on the systems affected, the sensitivity of the data involved, and how quickly the organization responds. Common business consequences include:

• Operational downtime: Disrupted applications, unavailable systems, or impaired network connectivity can prevent employees from completing essential tasks and interrupt customer-facing services.
• Financial losses: Businesses may face incident investigation expenses, recovery costs, lost productivity, contractual penalties, or other costs associated with responding to a security incident.
• Data exposure: Unauthorized access to customer information, employee records, intellectual property, or business documents can create privacy, legal, and contractual obligations.
• Compliance and legal challenges: Depending on the information involved and applicable regulations, an incident may require formal notifications, investigations, remediation, or additional compliance measures.
• Reputational damage: Customers and business partners may lose confidence if an organization cannot adequately protect sensitive information or maintain reliable services.
• Reduced IT productivity: Internal teams may need to redirect resources from planned projects to incident investigation, containment, system restoration, and recovery.

These consequences can also affect one another. For example, a disruption to a critical business application may delay customer transactions while increasing support workloads and recovery expenses. To limit the impact, organizations should identify their most important business systems, understand dependencies between applications and infrastructure, establish recovery priorities, and define incident escalation procedures. Regular reviews of cybersecurity risks and operational resilience can help decision-makers determine where additional safeguards add the most value.

How Can Businesses Detect Cybersecurity Threats Early?

Early detection helps businesses identify suspicious activity before an incident causes extensive disruption or data loss. Although no monitoring approach can guarantee detection of every attack, organizations can improve visibility by collecting relevant security events, establishing normal activity patterns, and promptly investigating anomalies. Businesses should pay attention to several potential warning signs:

• Unusual login activity: Repeated failed authentication attempts, unexpected logins, or access from unfamiliar locations may warrant investigation.
• Unexpected network traffic: Unexplained traffic spikes, unusual outbound connections, or communication with unfamiliar external systems can indicate suspicious activity.
• Abnormal system behavior: Unexpected changes in system performance, unfamiliar processes, or unusual resource consumption may require technical investigation.
• Unexplained account or configuration changes: Review new privileged accounts, altered permissions, or unexpected security-setting changes.
• Alerts across multiple systems: Related alerts from endpoints, firewalls, servers, and identity systems may indicate a broader incident rather than an isolated event.

To make these signals useful, organizations should establish a consistent detection and response process. This includes collecting logs from relevant systems, setting alert thresholds, prioritizing alerts by business risk, assigning investigation responsibilities, and documenting escalation procedures. Security teams should also distinguish routine operational anomalies from events that require immediate action. Correlating information across multiple systems can provide better context than investigating each alert independently. For businesses with limited internal security resources, external monitoring support can improve visibility and help with alert review and escalation.
