Unleashing improved context for threat actor activity with our Cloudforce One threat events platform

Today, one of the greatest challenges that cyber defenders face is analyzing detection hits from indicator feeds, which provide metadata about specific indicators of compromise (IOCs), like IP addresses, ASNs, domains, URLs, and hashes. While indicator feeds have proliferated across the threat intelligence industry, most feeds contain no contextual information about why an indicator was placed on the feed. Another limitation of most feeds today is that they focus solely on blockable indicators and cannot easily accommodate more complex cases, such as a threat actor exploiting a CVE or an insider threat. Instead, this sort of complex threat intelligence is left for long form reporting. However, long-form reporting comes with its own challenges, such as the time required for writing and editing, which can lead to significant delays in releasing timely threat intelligence.

To help address these challenges, we are excited to launch our threat events platform for Cloudforce One customers. Every day, Cloudflare blocks billions of cyber threats. This new platform contains contextual data about the threats we monitor and mitigate on the Cloudflare network and is designed to empower security practitioners and decision makers with actionable insights from a global perspective. 

On average, we process 71 Continue reading

Enhanced security and simplified controls with automated botnet protection, cipher suite selection, and URL Scanner updates

At Cloudflare, we are constantly innovating and launching new features and capabilities across our product portfolio. Today, we're releasing a number of new features aimed at improving the security tools available to our customers.

Automated security level: Cloudflare’s Security Level setting has been improved and no longer requires manual configuration. By integrating botnet data along with other request rate signals, all customers are protected from confirmed known malicious botnet traffic without any action required.

Cipher suite selection: You now have greater control over encryption settings via the Cloudflare dashboard, including specific cipher suite selection based on our client or compliance requirements.

Improved URL scanner: New features include bulk scanning, similarity search, location picker and more.

These updates are designed to give you more power and flexibility when managing online security, from proactive threat detection to granular control over encryption settings.

Cloudflare’s Security Level feature was designed to protect customer websites from malicious activity.

Available to all Cloudflare customers, including the free tier, it has always had very simple logic: if a connecting client IP address has shown malicious behavior across our network, issue a managed challenge. The system tracks malicious behavior Continue reading

Enhance your website’s security with Cloudflare’s free security.txt generator

Meet Georgia, a diligent website administrator at a growing e-commerce company. Every day, Georgia juggles multiple tasks, from managing server uptime to ensuring customer data security. One morning, Georgia receives an email from a security researcher who discovered a potential vulnerability on the website. The researcher struggled to find the right contact information, leading to delays in reporting the issue. Georgia realizes the need for a standardized way to communicate with security researchers, ensuring that vulnerabilities are reported swiftly and efficiently. This is where security.txt comes in.

Security.txt is becoming a widely adopted standard among security-conscious organizations. By providing a common location and format for vulnerability disclosure information, it helps bridge the gap between security researchers and organizations. This initiative is supported by major companies and aligns with global security best practices. By offering an automated security.txt generator for free, we aim to empower all of our users to enhance their security measures without additional costs.

In 2020, Cloudflare published the Cloudflare Worker for the security.txt generator as an open-source project on GitHub, demonstrating our commitment to enhancing web security. This tool is actively used Continue reading

Treasury and PNNL threat data now available for Financial sector customers to secure applications

Following the White House’s National Cybersecurity Strategy, which underscores the importance of fostering public-private partnerships to enhance the security of critical sectors, Cloudflare is happy to announce a strategic partnership with the United States Department of the Treasury and the Department of Energy’s Pacific Northwest National Laboratory (PNNL) to create Custom Indicator Feeds that enable customers to integrate approved threat intelligence feeds directly into Cloudflare's platform.

Our partnership with the Department of the Treasury and PNNL offers approved financial services institutions privileged access to threat data that was previously exclusive to the government. The feed, exposed as a Custom Indicator Feed, collects advanced insights from the Department of the Treasury and the federal government's exclusive sources. Starting today, financial institutions can create DNS filtering policies through Cloudflare’s Gateway product that leverage threat data directly from these government bodies. These policies are crucial for protecting organizations from malicious links and phishing attempts specifically targeting the financial sector.

This initiative not only supports the federal effort to strengthen cybersecurity within critical infrastructure including the financial sector, for which the Treasury is the designated lead agency, but also contributes directly to the ongoing improvement of our shared security capabilities.

Why we partnered Continue reading

Secure your unprotected assets with Security Center: quick view for CISOs

We understand that one of the significant hurdles faced by our customers, especially larger organizations, is obtaining a clear view of the deployment of Cloudflare services throughout their vast and complex infrastructures. The question isn't just whether Cloudflare is deployed, but whether it's fully optimized across every asset and service. Addressing this challenge head-on, we're rolling out a new feature set designed to provide better visibility and control over your security posture.

The problem we are addressing

The core problem we're tackling is the growing complexity of cyber threats and the expanding attack surface, which complicates maintaining a strong security posture for our customers.

It's not uncommon for organizations to deploy a variety of security solutions, including ours, without fully optimizing and implementing their configurations. This results in a false sense of security, underutilized investments and, more critically, exposed vulnerabilities. Our customers frequently express concerns about not having a clear picture of their security posture across their entire infrastructure, uncertain if critical assets are adequately protected or if specific Cloudflare security features could be better leveraged.

We want to bring users comprehensive visibility into their security configurations and the state of their deployments across Cloudflare's suite of products. By providing Continue reading

Top 50 most impersonated brands in phishing attacks and new tools you can use to protect your employees from them

Someone in your organization may have just submitted an administrator username and password for an internal system to the wrong website. And just like that, an attacker is now able to exfiltrate sensitive data.

How did it all happen? A well crafted email.

Detecting, blocking, and mitigating the risks of phishing attacks is arguably one of the hardest challenges any security team is constantly facing.

Starting today, we are opening beta access to our new brand and anti-phishing tools directly from our Security Center dashboard, allowing you to catch and mitigate phishing campaigns targeting your organization even before they happen.

The challenge of phishing attacks

Perhaps the most publicized threat vector over the past several months has been phishing attacks. These attacks are highly sophisticated, difficult to detect, becoming more frequent, and can have devastating consequences for businesses that fall victim to them.

One of the biggest challenges in preventing phishing attacks is the sheer volume and the difficulty of distinguishing legitimate emails and websites from fraudulent ones. Even when users are vigilant, it can be hard to spot the subtle differences that attackers use to make their phishing emails and websites look convincing.

For example, last July our Cloudflare Continue reading
