High Availability
A high-availability infrastructure is designed to not only withstand relentless cyberattacks but also possesses the technical sophistication to autonomously detect, mitigate, and heal vulnerabilities in real time. This ensures not just the uninterrupted continuity of services but also reinforces the very foundation of cybersecurity—ensuring that data remains secure and critical operations remain untainted, even amid an ever-evolving threat landscape.
