CloudBox

Local DNS cache for exceptional performance and granular control

The Problem

What is CloudBox and how does it work?

CloudBox is an exclusive FlashStart application designed to optimize DNS request and resolution processes by acting as an intermediate cache between users and the FlashStart cloud, where security intelligence is applied. Available as both a physical and virtual appliance, CloudBox stores DNS queries along with their corresponding responses or block decisions, allowing repeated requests to be resolved locally. This significantly reduces latency and improves overall network performance. When combined with FlashStart’s Anycast network—ranked among the fastest globally—the use of CloudBox brings DNS response times close to zero, ensuring fast, reliable, and uninterrupted browsing experiences.

100%

local resolution for repeated DNS requests – CloudBox autonomously responds to previously resolved queries, improving speed and stability.

1

centralized cache per network – a single CloudBox optimizes DNS performance for all users, devices, and locations.

2

deployment models available – CloudBox can be installed as a physical appliance or as a virtual machine to fit different infrastructures.

24/7

DNS availability – local caching ensures continuity even during connectivity or latency issues.

Enterprise integration and resilient performance

Modern IT environments are increasingly hybrid and distributed, making consistent DNS performance and policy enforcement a key challenge. CloudBox enhances reliability by caching DNS requests locally, reducing dependency on the cloud and ensuring stable performance even during connectivity issues. In addition, CloudBox enables granular user- and group-based filtering through profile encoding, embedding policy information into DNS queries to apply different security rules by user, device, or schedule. With native integration with Microsoft Active Directory and common RMM tools, organizations can centrally manage and consistently enforce fine-grained policies across complex environments.
