Why Do SMEs Become Cyberattack Targets?

Small and medium-sized enterprises (SMEs) are becoming increasingly attractive targets for cybercriminals. The main reason is that most SMEs view cybersecurity as a concern only large companies face and do not allocate sufficient budget to this area. Yet a ransomware attack or data breach can mean the complete halt of operations and even bankruptcy for an SME. At Tekur Bilisim, in our Istanbul-based operations, we observe that attackers now use automated tools to scan thousands of SMEs simultaneously and find the weakest link.

The traditional “one antivirus is enough” approach has lost its validity in today’s complex threat landscape. While SMEs may not have infrastructures as complex as large-scale companies, they hold valuable assets such as customer data, intellectual property, and financial information. For this reason, scaling enterprise cybersecurity strategies according to the size and risk profile of the business is vital. At Tekur, we analyze each SME’s unique dynamics and offer budget-friendly yet effective solutions.

Tekur Bilisim’s End-to-End Cybersecurity Approach

At Tekur Bilisim, we treat cybersecurity not as a product but as a process. Our end-to-end approach covers all stages, starting with risk analysis and extending to firewall configuration, endpoint protection, network monitoring, and incident response. Our goal is to ensure our clients are prepared not only for today’s threats but also for tomorrow’s. This approach aims to establish a proactive defense mechanism rather than passive protection.

One of the most critical steps in this process is starting with the right cybersecurity consultancy service. Our expert team first evaluates your current situation, identifies vulnerabilities, and creates a security roadmap tailored to you. We then deploy the technologies and processes needed to implement this roadmap. For example, weak password policies and an outdated VPN server we identified at one client were closed in a short time, preventing a potential breach.

Field Lesson 1: Seeing Beyond the “Firewall”

Many SMEs assume the job is done once they have purchased and installed the hardware that comes to mind first when cybersecurity is mentioned: the firewall. However, a situation we frequently encounter in the field is that these devices run with default settings or are never updated. This is like locking your front door and leaving the key under the doormat. At Tekur Bilisim, we emphasize that firewall configuration must be customized to your company’s workflows and traffic profile.

Another critical point is internal threats. Employees’ negligence or malicious actions can be far more destructive than external attacks. For this reason, we offer solutions that analyze not only the network perimeter but also user behavior. Through 24/7 monitoring provided under managed security services, we detect and respond to abnormal activity instantly.

Proactive Protection with Managed Security Services (MSS)

For SMEs operating in an intensely competitive business hub like Istanbul, maintaining an in-house 24/7 security team can be costly and inefficient. This is where managed security services (MSS) come into play. At Tekur Bilisim, we manage your security infrastructure on your behalf, analyze threats, and carry out the necessary interventions. This way, you can focus on your core business.

The main solutions we offer under MSS include:

• 24/7 Security Monitoring and Incident Response: Through our SIEM (Security Information and Event Management) systems, your network traffic, servers, and endpoints are continuously monitored.
• Firewall and VPN Management: We handle the configuration, updates, and maintenance of your enterprise firewalls.
• Endpoint Protection (EDR): We detect and block advanced threats (ransomware, malware) on your computers and servers.
• Regular Vulnerability Scanning and Penetration Testing: We periodically scan and report vulnerabilities in your systems.
• Backup and Disaster Recovery: We develop backup strategies that ensure your data security and business continuity.

The greatest advantage of these services is having an enterprise-grade Security Operations Center (SOC) at a fixed cost. Especially for companies operating in Istanbul, working with a partner familiar with the dynamics of the Istanbul cybersecurity ecosystem allows you to act faster against local threats.

The Cornerstones of an Enterprise Cybersecurity Strategy

A successful enterprise cybersecurity strategy is focused more on people and processes than technology. At Tekur Bilisim, we always remind our clients of these three fundamental principles:

1. Awareness Training: Even the strongest firewall can be bypassed by a phishing email that an employee clicks on. Regular cybersecurity awareness training minimizes human-related errors. 2. Backup and Business Continuity: Applying the 3-2-1 rule (3 copies, 2 different media, 1 copy offline) is the most effective defense against ransomware attacks. 3. Principle of Least Privilege: Granting users and systems only the minimum authority required to do their jobs prevents a breach from spreading.

Field Lesson 2: A Lesson Drawn from a Ransomware Incident

Last year, a logistics firm operating in Istanbul became the target of ransomware because of an email attachment opened by an employee. All the company’s files were encrypted and a ransom of $10,000 was demanded. Fortunately, the firm had previously worked with us to set up a cloud-based backup system. By responding immediately to the incident, we cleaned the encrypted systems and seamlessly restored the data from the backups. This incident once again demonstrated the importance of proactive cybersecurity consultancy services and regular backups. The firm returned to operations within hours without paying any ransom.
