Best On-Premises Data Center Security Software of 2025

Your attack surface is the sum total of all attack vectors that can be used against your perimeter defenses. It is simply the amount of information that you are exposing the outside world. The attack surface is the most important thing hackers will need to exploit to break into your network. When attacking targets, professional hackers usually follow the cyber kill chains. Typically, the first step in this process is to survey the target's attack surfaces. This is called advanced reconnaissance. By reducing the attack surface, you can reduce the risk and prevent attacks from ever happening. The cyber kill chain is a method for categorizing and tracking all stages of a cyberattack, from early reconnaissance to the exfiltration data.

Comprehensive protection, oversight, and micro-segmentation of workloads are essential for private cloud and on-premises data center settings. This includes fortifying security and providing monitoring capabilities specifically designed for private cloud infrastructures and physical data centers, along with support for Docker containerization. Utilizing agentless protection for Docker containers allows for extensive application control paired with streamlined management. To defend against zero-day vulnerabilities, implementing application whitelisting, detailed intrusion prevention measures, and real-time file integrity monitoring (RT-FIM) is crucial. Additionally, ensuring the security of OpenStack deployments requires thorough hardening of the Keystone identity service module. Continuous monitoring of data center security is vital for maintaining safe operations in private clouds and physical environments. Moreover, enhancing security performance in VMware setups can be achieved through agentless antimalware solutions, alongside network intrusion prevention and file reputation services, which collectively contribute to a robust security posture. Ultimately, effective security measures are indispensable for safeguarding sensitive data within these infrastructures.
