Stay protected from web threats with browser isolation

Join free for a month Download installer

The web browser is the most important application for users to carry out tasks in everyday lives, but it is highly vulnerable to attacks. CloudMosa leverages the browser isolation technology to safeguard your web browsing in the cloud and keep threats like malware, ransomware, adware, and malicious links at bay. With an ever-increasing number of zero-day attacks out there, Puffin Secure Browser provides the most effective way to guard against them.

Compatible with macOS Sierra 10.12 or later.

Browser Isolation in the local sandbox is insufficient. All major browsers fell to white-hat hackers at Pwn2Own browser hacking competition every year. The most secure sandboxes from the most talented browser companies are simply not good enough.

Puffin implements Browser Isolation in the cloud sandbox. The cloud sandbox cannot isolate viruses 100% just like the local sandbox, but Puffin’s network protocol can isolate viruses 100%. The extreme robustness comes from the extreme simplicity. Puffin’s network protocol and data exchange is too lightweight to carry viruses from the cloud servers to the client devices.

This hyper secure technology is ingenuously unimaginable on other browsers like Chrome, Firefox, Edge and Safari.

$2 a device keeps hackers and zero-day attacks away

Safeguard your devices

Whenever a zero-day attack emerges, all devices running browsers other than Puffin are vulnerable to cyber exploits. Since your Puffin browsing sessions are in the cloud, your devices won't be affected by zero-day attacks.

Avoid cybersecurity threats

Whenever a browsing session ends, everything is purged and destroyed on our servers. You are always in a clean state and isolated from potential threats on the web.

Boost performance with our cloud rendering engine

Regardless of your device specifications, Puffin leverages the cloud computing resources on our servers and supercharges the browsing peformance.

  • Is Puffin Secure Browser free to download and use?

    Puffin Secure Browser provides one month free trial. You can join free for a month and we won't charge you until the following month on the date after your free trial ends.

  • Can I cancel Puffin Secure Browser subscription anytime?

    Yes. If you cancel with time left in your billing period, we'll let you browse until the account cancels automatically. However, cancelling the subscription plan during the free trial will take effect immediately.

  • Are there any limitations in the free trial of Puffin Secure Browser?

    Puffin Secure Browser offers a free month of service for new customers. You can enjoy all the service within the free trial period.

  • Why do I need a payment method to start a free trial?

    We ask for a payment method to ensure you don't have any interruption in service after the free trial. You will not be charged if you do not continue our service.

  • Is the subscription auto-renewing?

    Both the monthly and yearly subscriptions are auto-renewing. If you wish to stop using the service, you may cancel anytime on the monthly plan or during the eleventh month on the yearly plan. We will stop charging you as soon as the current billing cycle ends.

  • What is your refund policy?

    We do not offer refunds in the middle of a billing cycle to prevent any service interruption. If you cancel auto-renewal of the service, it will take effect on the next billing date on the monthly plan or the eleventh billing date on the yearly plan.

  • Why the first bill may be higher than usual?

    Your monthly bill starts at the beginning of each month. After your free trial ends, there are prorated charges if your subscription starts in the middle of a billing cycle. Thus, your first bill may include prorated charges for the first partial month and the fixed subscription fee for the next full month.

  • How is the monthly fee of the team plan calculated?

    Our pricing model gives you plenty of flexibility. When you sign up for a team account, you set up a budget as the fixed monthly fee to pay. Your budget reflects the number of devices you can use each month. If you need to use more devices, simply raise the budget amount, and we will allocate new seats to your license immediately. Lowering your budget would take effect the following month to prevent existing users from unexpectedly losing access to Puffin.

  • Do I need different licenses on each platform?

    No. Puffin comes in a single subscription for all supported platforms (Windows, macOS, and Linux). Pay once and use Puffin on all compatible devices.

  • How many devices can I activate with the Individual license?

    You can activate up to 3 devices with an Individual license.

  • Do I get updates for free?

    Once you subscribe to Puffin Secure Browser, you can always get new updates to the software without any additional charge.

  • What desktop and protocols does Puffin Secure Browser support?

    Puffin Secure Browser supports Windows 7 and 10 as either 32-bit or 64-bit desktop implementations and coming soon to Linux and Mac OS.

  • What are the benefits of Puffin Secure Browser over other browsers?

    The most secure way to browse the Internet is to have two physically separate computers. One computer is used for work and other important tasks in an isolated network, and the other computer is used for web browsing. If anything happens to the second computer, the first one will still remain safe. Based on this concept, CloudMosa now offers you a second computer in our cloud.

  • What "merchant name" will be listed on my credit card (bank) statement?

    The credit card charge will be in the name of "CloudMosa, Inc.", the publisher of "Puffin Browser".

Puffin Secure Browser requires a subscription
