Worth Reading: Does your hammer own you?
My friend Marjan Bradeško wrote a great article describing how we tend to forget common sense and rely too much on technology. I would strongly recommend you read it and start thinking about the choices you make when building a network with magic software-intent-defined-intelligent technology from your preferred vendor.

One more (Zero Trust) thing: Cloudflare Intrusion Detection System
Today, we’re very excited to announce our plans for Cloudflare Intrusion Detection System, a new product that monitors your network and alerts when an attack is suspected. With deep integration into Cloudflare One, Cloudflare Intrusion Detection System gives you a bird’s eye view of your entire global network and inspects all traffic for bad behavior, regardless of whether it came from outside or inside your network.
Analyze your network without doing the legwork
Enterprises build firewall rules to keep their networks safe from external and internal threats. When bad actors try to attack a network, those firewalls check if the attack matches a rule pattern. If it does, the firewall steps in and blocks the attack.
Teams used to configure those rules across physical firewall appliances, frequently of different makes and models, deployed to physical locations. Yesterday, we announced Magic Firewall, Cloudflare’s network-level firewall delivered in our data centers around the world. Your team can write a firewall rule once, deploy it to Cloudflare, and our global network will protect your offices and data centers without the need for on-premises hardware.
This is great if you know where attacks are coming from. If you don’t have that level Continue reading

Using Social Media Content for Screening in Recruitment and Selection: Pros and Cons for Employers
Social media has become a popular tool these days. Many organizations use social media content for screening in recruitment and selection to scan and shortlist the job candidates. They do it by learning more about them through Facebook, Twitter, Instagram, and many more platforms. They search for the candidates on these platforms to learn about their lifestyles, interests, and hobbies. In this way, they can deduce whether these candidates can serve as an asset to the organization or not. Thus, it has become a common recruitment process these days.
Just like everything has its pros and cons, using social media content for screening in recruitment and selection: pros and cons are present too. There has been a long debate on the pros and cons of this screening method. Let’s take a look at them below.
Pros of Using Social Media For Screening
· Insight into the Informal Life of the Job Candidate
The candidate tries to be as formal as possible during the job interview. They are pretending to be something they are actually not, because they want to impress the interviewer to land that job. Therefore, employers are not able to deduce what the candidate is actually Continue reading
In Africa, Strengthening Digital Infrastructure for a Safe Return to Schools
When COVID-19 struck Africa, governments imposed temporary or full shutdowns of education systems to contain its spread. At least 53 out of the 54 African countries took measures that canceled or partially closed schools. Kenya, for example, canceled the 2020 academic year in March, before changing its directives six months later to allow schools to reopen.
No Internet, No Schools
Across the Democratic Republic of Congo, Liberia, Nigeria, and South Africa, where governments imposed partial closure, the few students with access to the Internet, mobile devices, and computers continue learning. But for the majority, there is no schooling. Most can’t afford the cost of Internet data, and very few have access to smartphones and computers. They must improvise to learn, thus widening disparities between learners with Internet access and those without. How can Africa close this gap and offer equal learning opportunities to everyone?
As we gear up towards resuming formal education, there is general panic among parents about the implications resulting from the major learning disruptions. Could COVID-19 lead to a lost generation of students?
Solutions for a Safe Return
Fortunately, African decision-makers are shifting their positions on schools as we learn to live with COVID-19. Governments across the Continue reading
How our network powers Cloudflare One
Earlier this week, we announced Cloudflare One™, a unified approach to solving problems in enterprise networking and security. With Cloudflare One, your organization’s data centers, offices, and devices can all be protected and managed in a single control plane. Cloudflare’s network is central to the value of all of our products, and today I want to dive deeper into how our network powers Cloudflare One.
Over the past ten years, Cloudflare has encountered the same challenges that face every organization trying to grow and protect a global network: we need to protect our infrastructure and devices from attackers and malicious outsiders, but traditional solutions aren’t built for distributed networks and teams. And we need visibility into the activity across our network and applications, but stitching together logging and analytics tools across multiple solutions is painful and creates information gaps.
We’ve architected our network to meet these challenges, and with Cloudflare One, we’re extending the advantages of these decisions to your company’s network to help you solve them too.
Distribution
Enterprises and some small organizations alike have team members around the world. Legacy models of networking forced traffic back through central choke points, slowing down users and constraining network scale. Continue reading

Imposters Among Us
Have you been playing Among Us? If you haven’t, your kids definitely have. I found out about it a few weeks ago because my children suddenly became Batman-level detectives and knew how to ask the kinds of interview questions that would make the FBI proud. In short, the game is all about finding the imposters in your midst based on their behavior and voting them out of the group to win. Sometimes you get it right. Other times you get it wrong and vote out someone who was doing legitimate tasks. It’s all a matter of perception.
Now, let’s look at another situation where we see this kind of behavior in a different light. You probably guessed where this is going already. We’re going to talk about Imposter Syndrome in our non-gaming lives and how it affects us. We may even make reference to pop culture along the way.
Where You Need To Be
I was thinking about this because something I said a few years ago at Security Field Day 1 popped back up in my feed. I was giving a speech at the beginning of the first day to the delegates and I wanted them to know that Continue reading
Introducing Magic Firewall
Today we’re excited to announce Magic Firewall™, a network-level firewall delivered through Cloudflare to secure your enterprise. Magic Firewall covers your remote users, branch offices, data centers and cloud infrastructure. Best of all, it’s deeply integrated with Cloudflare One™, giving you a one-stop overview of everything that’s happening on your network.
Cloudflare Magic Transit™ secures IP subnets with the same DDoS protection technology that we built to keep our own global network secure. That helps ensure your network is safe from attack and available and it replaces physical appliances that have limits with Cloudflare’s network.
That still leaves some hardware onsite, though, for a different function: firewalls. Networks don’t just need protection from DDoS attacks; administrators need a way to set policies for all traffic entering and leaving the network. With Magic Firewall, we want to help your team deprecate those network firewall appliances and move that burden to the Cloudflare global network.
Firewall boxes are miserable to manage
Network firewalls have always been clunky. Not only are they expensive, they are bound by their own hardware constraints. If you need more CPU or memory, you have to buy more boxes. If you lack capacity, the entire network suffers, directly Continue reading

How small businesses can start using Cloudflare One today
Earlier this week, we announced Cloudflare One™, our comprehensive, cloud-based network-as-a-service solution. Cloudflare One improves network performance and security while reducing cost and complexity for companies of all sizes.
Cloudflare One is built to handle the scale and complexity of the largest corporate networks. But when it comes to network security and performance, the industry has focused all too often on the largest of customers with significant budgets and technology teams. At Cloudflare, we think it’s our opportunity and responsibility to serve everyone, and help companies of all sizes benefit from a better Internet.
This is Zero Trust Week at Cloudflare, and we’ve already talked about our mantra of Zero Trust for Everyone. As a quick refresher, Zero Trust is a security framework that assumes all networks, devices, and Internet destinations are inherently compromised and therefore should not be trusted. Cloudflare One facilitates Zero Trust security by securing how your users connect to corporate applications and the Internet at large.
As a small business network administrator, there are fundamentally three things you need to protect: devices, applications, and the network itself. Below, I’ll outline how you can secure devices whether they are in your office (DNS Filtering) or remote (WARP+ Continue reading
Introducing Cloudflare Browser Isolation beta
Reimagining the Browser
A web browser, the same application that connects users to the entire Internet, also connects you to all of the potentially harmful parts of the Internet. It’s an open door to nearly every connected system on the planet, which is powerful and terrifying.
We also rely on browsers more than ever. Most applications that we use live in a browser and that will continue to increase. For more and more organizations, a corporate laptop is just a managed web browser machine.
To keep those devices safe, and the data they hold or access, enterprises have started to deploy “browser isolation” services where the browser itself doesn’t run on the machine. Instead, the browser runs on a virtual machine in a cloud provider somewhere. By running away from the device, threats from the browser stay on that virtual machine somewhere in the cloud.
However, most isolation solutions take one of two approaches that both ruin the convenience and flexibility of a web browser:
- Record the isolated browser and send a live stream of it to the user, which is slow and makes it difficult to do basic things like input text to a form.
- Unpack the webpage, inspect Continue reading
