Mainframes have been at the heart of many large organizations: banks, insurance companies, public administrations, energy companies, and large retailers continue to rely on them to process critical operations, manage huge volumes of data, and ensure business continuity.<\/span><\/p>\n

However, this historical reliability has, in some cases, led to a false sense of security.<\/span><\/p>\n

Today, talking about<\/span> mainframe security<\/b> is no longer a technical matter reserved for specialized departments. It is a <\/span>strategic concern<\/b> that directly affects the reputation, operations, and economic viability of any company that depends on these systems.<\/span><\/p>\n

 <\/p>\n

The current role of the mainframe in the modern enterprise<\/b><\/h2>\n

Although technology discourse often revolves around the cloud, artificial intelligence, and microservices, the reality is that mainframes still process a significant share of global transactions. Many organizations have modernized their environments by connecting the mainframe to APIs, web applications, and external services. <\/span><\/p>\n

This new hybrid scenario has clear advantages, but also<\/span> expands the attack surface. <\/b>. The mainframe is no longer isolated in an internal “bubble”: it now communicates with multiple systems, users, and vendors. And every connection is a potential entry point. <\/span><\/p>\n

 <\/p>\n

Mainframe security: a risk that is often underestimated<\/b><\/h2>\n

One of the most common mistakes is thinking that the mainframe is secure \u201cby default.\u201d It is true that its architecture is robust, but <\/span>security does not depend solely on technology<\/b>; it also depends on how it is configured, managed, and monitored over time.<\/span><\/p>\n

In many corporate environments, worrying patterns continue to repeat themselves, such as<\/span> excessive privileges granted to some users,<\/b> inherited access from employees who changed positions or left the company, or outdated configurations that have not been updated to current standards.<\/span><\/p>\n

These factors create a breeding ground for<\/span> security flaws in mainframe environments<\/b>, especially when the system is integrated with more modern open platforms.<\/p>\n

The real impact of a breach in a mainframe<\/b><\/h3>\n

When an incident affects a peripheral system, the damage is usually limited. But when the problem is on the mainframe, <\/span>the consequences multiply<\/b>.<\/span><\/p>\n
