Three Reasons IPS/IDS Will Remain Despite the Shift to Cloud and Zero Trust

With the rapid shift to cloud computing and zero-trust security, traditional solutions such as IPS/IDS are sometimes viewed as having outlived their usefulness.
However, the need for IPS/IDS for intrusion prevention/prevention remains as strong as ever.

IPS/IDS, along with firewalls and anti-virus software, have long been used as the core of network perimeter protection.
In recent years, as the use of cloud computing has progressed and security thinking has shifted toward zero-trust, the view has emerged that on-premise defense functions may no longer be necessary.

However, the reality is that most companies, with a few exceptions, are using both on-premise and cloud computing, and in some cases are returning from the cloud to on-premise, so it is unlikely that the need for IPS/IDS will disappear all at once.
In addition to the existence of psychological resistance to placing personal and confidential information in the cloud and restrictions imposed by laws and regulations, systems that face the outside world, such as web servers, mail servers, and DNS servers, will remain after the shift to cloud computing,
IPS/IDS remains effective as a mechanism to protect them.

In addition to explaining “3 reasons why IPS/IDS will remain” from an expert’s point of view, we will also discuss future security trends, such as log correlation analysis using generated AI,
