What are the cyber threats you need to know as a business owner?

Modern business increasingly relies on technological solutions that increase efficiency through automation and scalability. Email systems, online banking, CRM, online sales platforms, and remote work tools significantly simplify daily work, regardless of industry. Digital solutions significantly streamline the work of businesses, but they also increase the risk of cyberattacks. Cybercriminals no longer target only large corporations. Attacks are increasingly targeting smaller businesses, which often lack advanced security measures or dedicated IT departments. This directly impacts a company’s IT security. Even a single incident can lead to data loss, operational downtime, financial losses, and a loss of customer trust. In 2025, the CERT Polska team recorded 152% more security incidents than the previous year. The number of cyberattacks is growing year on year. The development of artificial intelligence, automation, and business digitization has allowed criminals to operate faster, more effectively, and on a larger scale than ever before. Companies store vast amounts of internal and customer data, making them attractive targets for hackers. This forces businesses and organizations to continually raise employee awareness of online threats and invest in their company’s cybersecurity.

The most common types of cyber ​​threats to businesses

Regardless of company size, any company using the internet and digital technologies can become a target for attack. Cybercriminals use both advanced technical tools and simple human error to gain access to company data, funds, or systems. Understanding the most common types of cyber threats allows you to better prepare your company for potential threats and reduce the risk of serious financial and reputational damage:

Phishing is one of the most commonly used cyberattack methods. It involves impersonating trusted individuals or institutions to extort confidential information such as passwords, login credentials, or banking information.

Ransomware is an exceptionally dangerous type of attack that encrypts company data. After blocking access to files, cybercriminals demand a ransom for their recovery. In many cases, companies do not regain full access to their data even after paying the ransom.

Malware is a general term for malicious software designed to damage a system, steal data, or take control of a device. Malware can operate undetected for long periods, collecting data or enabling cybercriminals to further exploit a company’s network.

DDoS attacks (Distributed Denial of Service) overload servers or websites with a huge number of requests. As a result, the system stops working or runs very slowly.

Attacks on passwords and user accounts. Many companies still use weak or repetitive passwords, significantly increasing the risk of compromise. Cybercriminals use automated password guessing tools and data from previous leaks. The lack of multi-factor authentication further increases the risk.

Employee attacks and social engineering. Cybercriminals are increasingly using psychological manipulation instead of advanced technical techniques. This is known as social engineering. Social engineering attacks are effective because they rely on haste, stress, or trust.

Threats associated with remote work. Remote work has increased the number of potential security holes. The use of personal devices, unsecured Wi-Fi networks, and a lack of appropriate procedures can facilitate cybercriminals’ access to company systems.

Phishing and how to protect yourself against it

Cybercriminals use fake messages and psychological manipulation to extort confidential data, gain access to company systems, or persuade employees to perform specific actions, such as transferring money or downloading a malicious file. Phishing typically employs a similar tactic. The attacker sends a message that appears credible and instills a sense of urgency or trust. This could include information about an unpaid invoice, a password change notification, or information about a courier delivery. After clicking a link or opening an attachment, a user can unknowingly provide data to cybercriminals or install malware. The most important element of phishing protection is team education. Employees should know how to recognize suspicious messages and what information should not be shared. Implementing multi-factor authentication significantly hinders cybercriminals from taking over accounts, even if they know the user’s password. Additional layers of security can include an SMS code, an authentication application, or a security key. Furthermore, employees should use unique, long, and difficult-to-guess passwords and password managers. Using the same passwords across multiple systems significantly increases the risk of hacking. It’s also worth using security software, including anti-phishing protection and threat detection systems.

Ransomware: What are the threats and how to counter them?

Ransomware is one of the most dangerous types of cyber threats to businesses. Malware encrypts company data and blocks access to systems, and cybercriminals demand ransom for file recovery. These types of attacks can paralyze a company’s operations in minutes, denying access to data, and generating significant financial and reputational damage. Importantly, ransomware victims include not only large corporations but also small and medium-sized businesses, which often lack adequate security measures. Early detection of an attack can mitigate its impact. Companies should be alert to the following signals: file access issues, unusual user activity, messages about data encryption, and increased network traffic. Modern security systems (EDR/XDR) can automatically detect suspicious activity and block some threats before data encryption begins. Backups are one of the most effective methods of protecting against ransomware. Backups should be: performed regularly, stored outside the company’s main network, properly secured, and regularly tested for data recovery. Thanks to backups, the company can recover data without having to pay a ransom.

Basic principles of IT security in the company

Properly protecting systems, data, and devices helps reduce the risk of information loss, business downtime, and costly cybercrime-related incidents. Cybersecurity isn’t just about modern software. Equally important are procedures, employee awareness, and regular preventative measures that help detect and eliminate threats before they lead to serious problems. Key principles and actions that enhance security and protection against potential attacks:
– using strong and unique passwords,
– implementing multi-factor authentication,
– regularly updating systems and software,
– creating data backups,
– training employees in cybersecurity,
– assigning the least possible privileges,
– monitoring and responding to incidents.

The importance of regular security audits

An IT security audit is a comprehensive analysis of a company’s systems, networks, devices, and cybersecurity procedures. Its goal is to verify whether the security measures in place are effective and whether the organization is adequately prepared for potential threats. Cybersecurity should be considered an ongoing process, not a one-time activity. Companies that regularly maintain the security of their systems and conduct regular security audits are much better prepared to protect digitally processed corporate data. A security audit allows for a thorough analysis of the company’s IT infrastructure, detecting potential vulnerabilities, and assessing the level of data and system protection. This allows the company to identify weak points before they are exploited by cybercriminals. Audits often reveal that threats stem not only from IT systems but also from human error. Analysis of procedures and employee behaviors allows for the identification of areas requiring additional training and improvement.
