The global IT & telecom cyber security market was valued at USD 35.11 billion in 2024 and is projected to reach USD 76.73 billion by 2030, registering a CAGR of 14.2% from 2025 to 2030. The rising vulnerability of the IT and telecommunications sectors to cyber-attacks-driven by massive data volumes and highly interconnected systems-continues to propel market growth.

Increasing incidents of ransomware, DDoS attacks, phishing, and insider threats are prompting organizations to invest heavily in advanced cybersecurity solutions to protect their infrastructure and customer data. This escalating threat environment is significantly boosting the demand for cybersecurity technologies and managed services.

The rapid shift toward cloud-based environments has introduced new layers of complexity and risk. As IT and telecom companies migrate applications, workloads, and sensitive information to the cloud, the potential for unauthorized access and data breaches increases. This has accelerated the adoption of specialized cloud security tools such as cloud access security brokers (CASBs), encryption solutions, and identity and access management (IAM) systems. The growing prevalence of hybrid and multi-cloud architectures further amplifies the need for tailored security solutions capable of safeguarding data across distributed environments. Additionally, regulatory compliance requirements surrounding data protection continue to drive cloud security adoption across industries.

The rollout of 5G networks marks a transformative advancement in telecommunications but simultaneously introduces new cybersecurity challenges. While 5G offers faster speeds and reduced latency, its decentralized network structure and proliferation of connected devices heighten security risks. As a result, telecom operators are increasingly investing in secure network slicing, zero-trust architecture, and advanced threat detection solutions to mitigate these vulnerabilities. According to 5G Americas, global 5G connections reached nearly 2 billion in Q1 2024, with 185 million new connections added. This number is expected to rise to 7.7 billion by 2028. In North America, 5G represents 32% of all wireless cellular connections-double the global average-supported by an 11% growth that added 22 million new connections during this period.
