Challenges in Legacy System Integration Impacting Market Growth

Mainframes remain the backbone of global enterprise computing, supporting mission-critical operations across banking, government, healthcare, retail, and large-scale transaction environments. As cyber threats grow increasingly sophisticated, organizations must prioritize strong security frameworks to safeguard sensitive data and maintain operational continuity. The rising need for robust authentication, encryption, threat detection, and compliance management is driving significant interest in the mainframe security market, which is projected to expand from USD 81.68 million in 2023 to USD 162.76 million by 2030, advancing at a CAGR of 9.00%.

Growing Cybersecurity Threats Elevating Mainframe Protection Needs

Despite being known for unmatched stability and reliability, mainframes face increasing attacks due to the vast amount of financial, personal, and confidential data they store. Modern cybercrime has evolved to target legacy systems through credential theft, unauthorized access, misconfigurations, insider threats, and APIs exposed during digital transformation.
