Introducing Cloudflare for Teams

Introducing Cloudflare for Teams

Ten years ago, when Cloudflare was created, the Internet was a place that people visited. People still talked about ‘surfing the web’ and the iPhone was less than two years old, but on July 4, 2009 large scale DDoS attacks were launched against websites in the US and South Korea.

Those attacks highlighted how fragile the Internet was and how all of us were becoming dependent on access to the web as part of our daily lives.

Fast forward ten years and the speed, reliability and safety of the Internet is paramount as our private and work lives depend on it.

We started Cloudflare to solve one half of every IT organization's challenge: how do you ensure the resources and infrastructure that you expose to the Internet are safe from attack, fast, and reliable. We saw that the world was moving away from hardware and software to solve these problems and instead wanted a scalable service that would work around the world.

To deliver that, we built one of the world's largest networks. Today our network spans more than 200 cities worldwide and is within milliseconds of nearly everyone connected to the Internet. We have built the capacity to stand Continue reading

Security on the Internet with Cloudflare for Teams

Security on the Internet with Cloudflare for Teams

Your experience using the Internet has continued to improve over time. It’s gotten faster, safer, and more reliable. However, you probably have to use a different, worse, equivalent of it when you do your work. While the Internet kept getting better, businesses and their employees were stuck using their own private networks.

In those networks, teams hosted their own applications, stored their own data, and protected all of it by building a castle and moat around that private world. This model hid internally managed resources behind VPN appliances and on-premise firewall hardware. The experience was awful, for users and administrators alike. While the rest of the Internet became more performant and more reliable, business users were stuck in an alternate universe.

That legacy approach was less secure and slower than teams wanted, but the corporate perimeter mostly worked for a time. However, that began to fall apart with the rise of cloud-delivered applications. Businesses migrated to SaaS versions of software that previously lived in that castle and behind that moat. Users needed to connect to the public Internet to do their jobs, and attackers made the Internet unsafe in sophisticated, unpredictable ways - which opened up every business to  a Continue reading

Cloudflare + Remote Browser Isolation

Cloudflare + Remote Browser Isolation

Cloudflare announced today that it has purchased S2 Systems Corporation, a Seattle-area startup that has built an innovative remote browser isolation solution unlike any other currently in the market. The majority of endpoint compromises involve web browsers — by putting space between users’ devices and where web code executes, browser isolation makes endpoints substantially more secure. In this blog post, I’ll discuss what browser isolation is, why it is important, how the S2 Systems cloud browser works, and how it fits with Cloudflare’s mission to help build a better Internet.

What’s wrong with web browsing?

It’s been more than 30 years since Tim Berners-Lee wrote the project proposal defining the technology underlying what we now call the world wide web. What Berners-Lee envisioned as being useful for “several thousand people, many of them very creative, all working toward common goals[1] has grown to become a fundamental part of commerce, business, the global economy, and an integral part of society used by more than 58% of the world’s population[2].

The world wide web and web browsers have unequivocally become the platform for much of the productive work (and play) people do every day. However, as the pervasiveness Continue reading

BrandPost: WAN Transformation – Security First or Network First?

It’s an exciting time in Wide Area Networking. With the rapid adoption of software-defined wide area networking (SD-WAN) architectures, we’re experiencing the biggest transformation in the WAN since the introduction of MPLS back in the late 90s.As with all new technologies, there is a lot of hype and a stampede of companies looking to capitalize on a hot new category. At last count, there were about 70 companies with marketing messages all vying to hop on the five letter “S-D-W-A-N” bandwagon.Interestingly, in the newly Gartner 2019 Magic Quadrant for WAN Edge Infrastructure, there are only two companies positioned as Leaders, Silver Peak and VMware. Seventeen others are positioned across the Niche, Visionary and Challenger quadrants. Ten additional companies are listed but didn’t meet the qualification criteria for inclusion in the Magic Quadrant.To read this article in full, please click here

There Is no Layer-2 in Public Cloud

The amount of layer-2 tricks we use to make enterprise networking work never ceases to amaze me - from shared IP addresses used by various clustering solutions (because it’s too hard to read the manuals and configure DNS) to shared MAC addresses used by first-hop router redundancy protocols (because it would be really hard to send a Gratuitous ARP message on failover) and all sorts of shenanigans we’re forced to engage in to enable running servers to be moved willy-nilly around the Earth.

Generating numeric sequences with the Linux seq command

One of the easiest ways to generate a list of numbers in Linux is to use the seq (sequence) command. In its simplest form, seq will take a single number and then list all the numbers from 1 to that number. For example:$ seq 5 1 2 3 4 5 Unless directed otherwise, seq always starts with 1. You can start a sequence with a different number by inserting it before the final number.$ seq 3 5 3 4 5 Specifying an increment You can also specify an increment. Say you want to list multiples of 3. Specify your starting point (first 3 in this example), increment (second 3) and end point (18).To read this article in full, please click here

Researchers aim for transistors that compute and store in one component

Researchers at Purdue University have made progress towards an elusive goal: building a transistor that can both process and store information. In the future, a single on-chip component could integrate the processing functions of transistors with the storage capabilities of ferroelectric RAM, potentially creating a process-memory combo that enables faster computing and is just atoms thick.The ability to cram more functions onto a chip, allowing for greater speed and power without increasing the footprint, is a core goal of electronics design. To get where they are today, engineers at Purdue had to overcome incompatibilities between transistors – the switching and amplification mechanisms used in almost all electronics – and ferroelectric RAM. Ferroelectric RAM is higher-performing memory technology; the material introduces non-volatility, which means it retains information when power is lost, unlike traditional dielectric-layer-constructed DRAM.To read this article in full, please click here

Wi-Fi 6 is slowly gathering steam

The next big wave of Wi-Fi technology, 802.11ax, is going to become more commonplace in enterprise installations over the course of the coming year, just as the marketing teams for the makers of Wi-Fi equivalent will have you believe. Yet the rosiest predictions of revolutionary change in what enterprise Wi-Fi is capable of are still a bit farther off than 2020, according to industry experts.To read this article in full, please click here(Insider Story)

Wi-Fi 6 will slowly gather steam in 2020

The next big wave of Wi-Fi technology, 802.11ax, is going to become more commonplace in enterprise installations over the course of the coming year, just as the marketing teams for the makers of Wi-Fi equivalent will have you believe. Yet the rosiest predictions of revolutionary change in what enterprise Wi-Fi is capable of are still a bit farther off than 2020, according to industry experts.The crux of the matter is that, while access points with 802.11ax’s Wi-Fi 6 branding will steadily move into enterprise deployments in, the broader Wi-Fi ecosystem will not be dominated by the new standard for several years, according to Farpoint Group principal Craig Mathias.To read this article in full, please click here

A new spin on interconnects for colocation data centers

It has been almost a year since I first wrote about Stateless, Inc., a startup devoted to bringing software-defined interconnects (SD-IX) to colocation data centers. At that time, the company was just announcing its plans to reinvent the means to connect workloads across data centers, hyperscale clouds and on-premises footprints using SD-IX. The intent was to give colo service providers a simpler way to quickly deploy network services for their tenants. Those plans have come to fruition and the company has announced the general availability (GA) of its Luxon SD-IX platform.To read this article in full, please click here
