Introducing SSH command logging
SSH (Secure Shell Protocol) is an important protocol for managing remote machines. It provides a way for infrastructure teams to remotely and securely manage their fleet of machines. SSH was a step-up in security from other protocols like telnet. It ensures encrypted traffic and enforces per user controls over access to a particular machine. However, it can still introduce a significant security risk. SSH, especially root access, is destructive in the wrong hands (think rm -r *) and can be difficult to track. Logging and securing user actions via SSH typically requires custom development or restrictive software deployments. We’re excited to announce SSH command logging as part of Cloudflare Zero Trust.
Securing SSH access
Security teams put significant effort into securing SSH across their organization because of the negative impact it can have in the wrong hands. Traditional SSH security consists of strong authentication, like certificate based authentication, and tight controls on who has “root” access. Additionally, VPNs and IP allow lists are used to further protect a machine from being publicly accessible to the Internet. The security challenges that remain are visibility and potential for lateral movement.
SSH commands to a remote machine are end-to-end encrypted, which means Continue reading
Cloudflare partners with Microsoft to protect joint customers with a Global Zero Trust Network
As a company, we are constantly asking ourselves what we can do to provide more value to our customers, including integrated solutions with our partners. Joint customers benefit from our integrations below with Azure Active Directory by:
First, centralized identity and access management via Azure Active Directory which provides single sign-on, multifactor authentication, and access via conditional authentication.
Second, policy oriented access to specific applications using Cloudflare Access—a VPN replacement service.
Third, an additional layer of security for internal applications by connecting them to Cloudflare global network and not having to open them up to the whole Internet.
Let’s step back a bit.
Why Zero Trust?
Companies of all sizes are faced with an accelerating digital transformation of their IT stack and an increasingly distributed workforce, changing the definition of the security perimeter. We are moving away from the castle and moat model to the whole Internet, requiring security checks for every user accessing every resource. As a result, all companies, especially those whose use of Azure’s broad cloud portfolio is increasing, are adopting Zero Trust architectures as an essential part of their cloud and SaaS journey.
Cloudflare Access provides secure access to Azure hosted applications and Continue reading
A bridge to Zero Trust
Cloudflare One enables customers to build their corporate networks on a faster, more secure Internet by connecting any source or destination and configuring routing, security, and performance policies from a single control plane. Today, we’re excited to announce another piece of the puzzle to help organizations on their journey from traditional network architecture to Zero Trust: the ability to route traffic from user devices with our lightweight roaming agent (WARP) installed to any network connected with our Magic IP-layer tunnels (Anycast GRE, IPsec, or CNI). From there, users can upgrade to Zero Trust over time, providing an easy path from traditional castle and moat to next-generation architecture.
The future of corporate networks
Customers we talk to describe three distinct phases of architecture for their corporate networks that mirror the shifts we’ve seen with storage and compute, just with a 10 to 20 year delay. Traditional networks (“Generation 1”) existed within the walls of a datacenter or headquarters, with business applications hosted on company-owned servers and access granted via private LAN or WAN through perimeter security appliances. As applications shifted to the cloud and users left the office, companies have adopted “Generation 2” technologies like SD-WAN Continue reading
Managing Clouds – Cloudflare CASB and our not so secret plan for what’s next
Last month we introduced Cloudflare’s new API–driven Cloud Access Security Broker (CASB) via the acquisition of Vectrix. As a quick recap, Cloudflare’s CASB helps IT and security teams detect security issues in and across their SaaS applications. We look at both data and users in SaaS apps to alert teams to issues ranging from unauthorized user access and file exposure to misconfigurations and shadow IT.
I’m excited to share two updates since we announced the introduction of CASB functionality to Cloudflare Zero Trust. First, we’ve heard from Cloudflare customers who cannot wait to deploy the CASB and want to use it in more depth. Today, we’re outlining what we’re building next, based on that feedback, to give you a preview of what you can expect. Second, we’re opening the sign-up for our beta, and I’m going to walk through what will be available to new users as they are invited from the waitlist.
What’s next in Cloudflare CASB?
The vision for Cloudflare’s API–driven CASB is to provide IT and security owners an easy-to-use, one-stop shop to protect the security of their data and users across their fleet of SaaS tools. Our goal is to make sure any IT or security Continue reading

Capturing Bird Photos
Continuing from the previous post which I have set up to install a bird feeder, I have mentioned that I would install a camera based on the https://mynaturewatch.net/daylight-camera-instructions project and I did install it, this took some really good photos and would like to share some of them.
Few points:
- The battery that I used is a 10000mAh power-bank and it lasted for 2-3 days
- The box that I used is a baby food box and I nailed them to the boundary wooden poles from inside.
- This Bird Feeder is not the one I 3d Printed, this is an old bird feeder that someone gave it to me
Glad to see these pics, many more to come with Idea to install and make it sustain through solar power

Defense in depth with Calico Cloud
Last month, we announced the launch of our active cloud-native application runtime security. Calico Cloud’s active runtime security helps security teams secure their containerized workloads with a holistic approach to threat detection, prevention, and mitigation.
As security teams look to secure these workloads, it’s also critical that they employ a defense-in-depth strategy. Calico Cloud’s active runtime security can detect, prevent, and mitigate threats across the entire cyber kill chain for containerized workloads.
What is the cyber kill chain?
The cyber kill chain is a framework used to track the steps a threat actor might take as they attempt to execute a cyber attack on your organization. The cyber kill chain was originally developed by Lockheed Martin to adapt the military concept that details the structure of an attack for cybersecurity threats. Today, this framework is used by security teams from a wide range of organizations to understand and respond to cybersecurity threats.
The Lockheed Martin cyber kill chain consists of seven stages:
- Reconnaissance: An attacker assesses potential targets and tactics for an attack
- Weaponization: An attacker prepares the attack by obtaining or setting up the appropriate infrastructure
- Delivery: An attacker launches their attack
- Exploitation: An attacker gains access to their Continue reading
Evolving Machine Learning to stop mobile bots
When we launched Bot Management three years ago, we started with the first version of our ML detection model. We used common bot user agents to train our model to identify bad bots. This model, ML1, was able to detect whether a request is a bot or a human request purely by using the request’s attributes. After this, we introduced a set of heuristics that we could use to quickly and confidently filter out the lowest hanging fruit of unwanted traffic. We have multiple heuristic types and hundreds of specific rules based on certain attributes of the request, many of which are very hard to spoof. But machine learning is a very important part of our bot management toolset.
We started with a static model because we were starting from scratch, and we were able to experiment quickly with aggregated HTTP analytics metadata. After we launched the model, we quickly gathered feedback from early bot management customers to identify where we performed well but also how we could improve. We saw attackers getting smart, and so we generated a new set of model features. Our heuristics were able to accurately identify various types of bad bots giving us much better Continue reading

Clientless Web Isolation is now generally available
Today, we’re excited to announce that Clientless Web Isolation is generally available. A new on-ramp for Browser Isolation that natively integrates Zero Trust Network Access (ZTNA) with the zero-day, phishing and data-loss protection benefits of remote browsing for users on any device browsing any website, internal app or SaaS application. All without needing to install any software or configure any certificates on the endpoint device.
Cloudflare’s clientless web isolation simplifies connections to remote browsers through a hyperlink (e.g.: https://<your-auth-domain>.cloudflareaccess.com/browser). We explored use cases in detail in our beta announcement post, but here’s a quick refresher on the use cases that clientless isolated browsing enables:
Share secure browsing across the entire team on any device
Simply navigating to Clientless Web Isolation will land your user such as an analyst, or researcher in a remote browser, ready to securely conduct their research or investigation without exposing their public IP or device to potentially malicious code on the target website.
Deep link into isolated browsing
Suspicious hyperlinks and PDF documents from sensitive applications can be opened in a remote browser by rewriting the link with the clientless endpoint. For example:
https://<authdomain>.cloudflareaccess.com/browser/https://www.example.com/suspiciouslink
This is Continue reading
Packet captures at the edge
Packet captures are a critical tool used by network and security engineers every day. As more network functions migrate from legacy on-prem hardware to cloud-native services, teams risk losing the visibility they used to get by capturing 100% of traffic funneled through a single device in a datacenter rack. We know having easy access to packet captures across all your network traffic is important for troubleshooting problems and deeply understanding traffic patterns, so today, we’re excited to announce the general availability of on-demand packet captures from Cloudflare’s global network.
What are packet captures and how are they used?
A packet capture is a file that contains all packets that were seen by a particular network box, usually a firewall or router, during a specific time frame. Packet captures are a powerful and commonly used tool for debugging network issues or getting better visibility into attack traffic to tighten security (e.g. by adding firewall rules to block a specific attack pattern).
A network engineer might use a pcap file in combination with other tools, like mtr, to troubleshoot problems with reachability to their network. For example, if an end user reports intermittent connectivity to a specific application, an engineer Continue reading
