In today’s digital world, the possibility of encountering cyber security threats increases day by day. Countries, companies and individuals are constantly developing innovations to ensure data security and protect against cyber attacks. In this context, e-mail security becomes especially important. In addition to being the primary means of communication in companies, email is one of the most preferred attack vectors for cybercriminals.

Threat Environment: Current Situation 2025-2026

Cyber ​​attacks are becoming more sophisticated every year. Ransomware attacks in Turkey increased by 47% in 2025. Targeted attacks now hit not only large institutions, but even SMEs with 50 people.

Attackers personalize phishing emails with artificial intelligence-powered tools. Now “Your cargo has arrived” Instead, they use highly convincing messages crafted with information extracted from the target’s LinkedIn profile. That’s why classical awareness training is not enough.

One of our customers encountered just such an attack last month. The fake invoice email sent to the finance department forged the CEO’s real signature. Fortunately, CloudSpark’s email security layer caught this.

Layers of Defense and Strategy

No single security product can protect you. A layered defense in depth approach is a must. Endpoint protection, network security, email filtering, identity management and data loss prevention—it all needs to be considered together.

Zero Trust architecture, “trust, always verify” is based on the principle. It doesn’t even trust traffic within the network. Each access request is evaluated with user ID, device status and location information.

Our SOC (Security Operations Center) team monitors 24/7. We analyzed 2.3 million security incidents last year. 1,847 of these were classified as real threats and were responded to within an average of 12 minutes.

Compliance and Legal Requirements

Within the scope of KVKK (Personal Data Protection Law), the data breach notification period is 72 hours. Within this period, you must detect the violation and inform the affected people and institution. Being caught unprepared means both legal and reputational risks.

ISO 27001, SOC 2 Type II, PCI DSS — there are different compliance frameworks depending on your industry. CloudSpark also provides consultancy to its customers in their compliance processes. We don’t just sell technology, we create a security culture.

Frequently Asked Questions

How much should the cyber security budget be?

It is recommended to allocate 10-15% of the IT budget to security. However, this percentage varies by sector — it can reach 20% in finance and healthcare. The important thing is to direct investment to the right areas. Instead of buying cheap antivirus and removing expensive SIEM, it is necessary to make a decision based on risk analysis.

Establishing a SOC team or outsourcing?

Establishing a SOC team of 50 people means an annual cost of 15-20 million TL. Managed SOC service corresponds to 20-30% of this cost. CloudSpark’s Managed SOC service provides 24/7 monitoring and instant response. Instead of having your team work 3 shifts with at least 5 security experts, leave it to us.

How often should penetration testing be done?

Comprehensive penetration testing is recommended at least once a year. After major changes (infrastructure migration, new application deployment) additional testing should be performed. The combination of black box, gray box and white box tests gives the most comprehensive results.
