How it works

The nuu:bit Image Optimization solution combines 3 distinctive backend capabilities into a single product offering that is proven to reliably reduce image payloads, and improve page load time by >60%:

  • Mobile device detection – based on WURFL device detection
  • Image resizing, cropping, and optimization
  • Global Content Delivery Network (CDN)

WURFL, the industry standard for device detection, is at the core of the nuu:bit Image Optimization solution technology solution. The WURFL Device Description Repository, containing over 65,000 device profiles, provides a 99% hit rate of accuracy in its ability to detect and proactively read devices.

Why nuu:bit?

The nuu:bit Image Optimization service offers the most seamless integration with the best performance.  Completing cloud services add unnecessary complexity to your workflow while offering poor quality or wrong sized images.  

Use nuu:bit, take the guess work out!


Use case e-commerce

How can images impact the effectiveness of a webpage? It’s widely reported that blog posts and news stories that feature images see over 90% more total views than pages without images. For eCommerce, shoppers say that quality product images are more important in driving purchasing decisions than product descriptions, product details, or ratings and reviews. And 67% of consumers say the quality of an image is “very important” in their decision to complete an online or mobile purchase. But 75% of shoppers will abandon a website – and potentially start shopping on a competitor’s site – if web pages take more than 3 seconds to load. 

nuu:bit Image Optimization actively addresses these key factors by providing:

  • Faster page loading: accelerating performance and reducing payloads by more than 60%
  • CDN Savings: you only pay for optimized, resized image bandwidth
  • Proactive device detection: accurately identifying and optimizing for a growing universe of mobile, desktop, and even wearable devices
  • Automatic image resizing: images are resized and cached for reduced traffic to origins, faster delivery to end users, and cost savings to your business
  • Simple deployment: easy integration with leading e-commerce platforms
  • Workflow streamlining: one master image is automatically right-sized for many different devices, web pages, and apps, with no changes required to the existing site workflow

Features Supported



The nuu:bit Cyber Security solution is the nuu:bit Cybersecurity suite. The Web Application Firewall or WAF is a customer managed WAF which protects a site from attacks. The WAF is an easy to deploy and easy to manage solution.


The nuu:bit’s WAF (Web Application Firewall) contains three key differentiators:

  • Customer managed – which provides higher security
  • Filters Get & Posts requests
  • Self-learning feature to enable an easy way for a customer to generate custom WAF rules

The nuu:bit Cyber Security solution is robust solution because it does not rely on a signature base like an antivirus and most WAFs, thus cannot be circumvented by an “unknown” attack pattern. The nuu:bit Cyber Security solution has a user-defined rulesets built into the platform in addition to the core ruleset which is extensible. The The nuu:bit Cyber Security solution solution can check different values, such as URLs, request parameters, cookies, headers, or the POST body. Automatic whitelist creation makes it easy deploy the firewall upstream and rule out 100 percent of false positives.

The nuu:bit Cyber Security solution has analytics to quickly view WAF events, event heat map to identify the attacker’s location as well as detailed event logs.

Static Caching

Static Caching

At nuu:bit, we offer a global CDN caching platform which allows our customers to define the following:

  • Which content should be cached on the CDN cache, and for how long
  • What browser caching setting should apply
  • How to handle URL query string parameters and HTTP cookies

Caching static content (like images, CSS, JS and video files) on what was known as the edge caching has been around for a while and remains to be a stable and a very efficient technique to improve the performance of a website or mobile application.

Our CDN global caching system supports highly custom caching rules. These rules are a set of parameters that change the caching behavior of one or more URLs that match a pattern, specified as either a wildcard expression or a Perl-compatible regular expression.

One of the technologies nuu:bit uses is Varnish, which allows our customers to directly use domain-specific language called Varnish Configuration Language, or VCL for short. This will allow for complete and total custom caching.



At nuu:bit, we understand the importance of cybersecurity, and we have provided an easy way to manage SSL security. The nuu:bit portal supports full self-servicing for SSL certificates. This saves our customers valuable time. Moreover, nuu:bit doesn’t charge our customers for custom SSL certificates whether they are a wildcard or not.

Securely upload and manage your own SSL certificates to be associated with your domains using SNI feature.

We also offer a tightly integrated SSL solution from GlobalSign, a Certificate Authority provider, to protect your web resources within minutes (we call the feature “SSL Names”). We support a domain control verification using email, HTML Meta-tag or Email.


Instant Purge

Instant Purge

The nuu:bit platform supports instant purge of cached object via customer portal or API. This allows for support for the caching of your transient data allowing for a more dynamic and rich end user experience. Using our fast purge solution, >95% of object purge commands are completed within 2 seconds globally. The instant purge functionality and API access allow you to cache even short-lived content, such as forum/comment pages, news, frequently updated product pages, and etc.

Best Practices

Best Practices

At nuu:bit, we are on the same team with our customers! We pick up our part of the responsibility by providing our customers an easy and predictable way to update the configurations with a built-in security.

Following best practices for enterprise-grade systems that are designed to serve critical web and mobile resources, we have implemented the following features:

  • Sandbox (we call it “staging”) environment to test your CDN configuration changes before deploying them in our global network and making them available for our customers’ end users
  • Detailed audit log for all changes performed on your CDN and mobile app resources
  • Visualization of CDN configuration changes and cache purges on traffic graphs
  • Configuration versioning
  • Optional two-factor authentication for customer portal users
DNS Service

DNS Service

At nuu:bit, we work with the best of breed DNS provider NS1. NS1 provides the world’s most intelligent DNS and traffic management solution, enabling content owners and developers to take unparalleled control over their traffic and infrastructure.

The platform supports FTP, SFTP, S3 containers or ElasticSearch targets for remote log storage.

TCP Acceleraiton

TCP Acceleraiton

DOTS (Dynamically Optimized Transport System) is the nuu:bit platform’s advanced and intelligent TCP congestion control algorithm designed specifically to improve last-mile Internet delivery. Our patent pending invention, outperforms existing CDN solutions by up to 3X.

DOTS does not require a software agent on the receiving end, as it is built with the focus to accelerate HTTP content delivery asymmetrically; this elegant yet powerful feature contrasts SDK’s requirement for special software to be compiled in the App that runs on the edge device. Leveraging DOTS, nuu:bit’s leading core technology with three key pending patents, we are sending data even faster and cheaper with ever increased efficiency. We gain 20% to 300% on web performance depending on the network conditions over the normal TCP protocol.
