The Security Architecture of SurferCloud UHost

The Modern Threat Landscape

As businesses move their core operations to the cloud, they become targets for increasingly sophisticated cyber-attacks. From Distributed Denial of Service (DDoS) attacks to ransomware, the stakes have never been higher. SurferCloud UHost is built with a "Security-First" philosophy, ensuring that your data remains your data.

Multi-Layered Defense Mechanism

Security at SurferCloud isn't just a single feature; it's a multi-layered architecture that protects the UHost instance from the physical hardware up to the application layer.

1. Virtual Private Cloud (VPC) Isolation

Every UHost instance operates within a VPC. This provides a logically isolated section of the SurferCloud network where you can define your own IP address range, create subnets, and configure route tables. This network isolation prevents "lateral movement"—a common tactic where hackers compromise one server to reach others on the same network.

2. High-Performance Security Groups

Our Security Groups act as a virtual firewall for your UHost instances. You can set granular inbound and outbound rules (Port, Protocol, IP) to control traffic. Since these rules are applied at the network level, malicious traffic is blocked before it even reaches your server's operating system, saving CPU resources.

Data Integrity and Disaster Recovery

Security also means protection against data loss.

• Distributed Storage: UHost uses a distributed storage system where every piece of data is replicated across multiple physical nodes. If a disk fails, the system automatically reconstructs the data from replicas without any service interruption.
• Snapshots and Backups: Users can create instant Snapshots of their UHost. This is your ultimate safety net against ransomware. If your server is compromised, you can roll back to a clean state in minutes.

99.95% Availability SLA

SurferCloud’s commitment to security and stability is backed by a professional SLA. Our data centers feature 24/7 physical security, redundant power supplies (UPS + Generators), and advanced cooling systems. We handle the "Heavy Lifting" of physical security so you can focus on your code.
