My two previous recent postings on AI covered “Agentic AI” and how that impacts cybersecurity and the eventual emergence of malicious agentic AI malware. Both of those articles started to touch on the idea of automated agentic AI defenses. This posting goes into a little more detail on what agentic AI defenses might mean. It starts with agentic AI, which is a collection of automated programs (i.e., bots or agents) working toward a common goal.

Today, Cato Networks published the 2025 Cato CTRL Threat Report. It is the inaugural annual threat report from Cato CTRL, the Cato Networks threat intelligence team. The key theme for this year’s report is artificial intelligence (AI), which reflects the current cybersecurity landscape where AI usage is skyrocketing among vendors—and threat actors. Within the report, we examine the security risks associated with LLMs and the increased adoption of AI applications within organizations in 2024.

Is true anonymity possible online? As more companies and governments threaten our online privacy, people are looking for more ways to browse the internet with increased privacy or total anonymity. We will therefore explore why people are choosing to browse the web anonymously, why it’s important, and popular tools to browse the web with increased privacy or total anonymity.

If you are a mature organization, you might manage an external IP block of 65,000 IP addresses (equivalent to a /16 network). In contrast, very large organizations like Apple may handle an astonishing 16.7 million IP addresses or more (about a /8 network). However, this isn’t the case for many of us. IP addresses are fixed assets and can be costly, so most modern organizations do not have a large number of directly assigned IP addresses for every service they expose to the internet.

Most countries have some sort of government agency dedicated to protecting digital infrastructure and promoting cybersecurity awareness. In the English-speaking world alone, the UK has the National Cyber Security Center (NCSC), the US has the National Institute of Standards and Technology (NIST), and Canada has the Canadian Centre for Cyber Security; chances are you’re already aware of them.

A newly identified cyber campaign has been actively targeting organizations across multiple sectors in Japan since January 2025. Threat actors of unknown origin have been exploiting CVE-2024-4577, a critical remote code execution (RCE) vulnerability in the PHP-CGI implementation of PHP on Windows, to gain unauthorized access to victim systems. This campaign has primarily impacted Japan’s technology, telecommunications, and e-commerce industries.

Developers are trapped in a loop: constantly chasing dependency upgrades to mitigate security risks or chasing down security reports of vulnerable code or findings in the CI pipeline. Developers often refer to this as “vulnerability fatigue,” a term commonly referenced in npm package install logs that list the newly introduced security vulnerabilities for third-party dependencies.

The Payment Card Industry Data Security Standard (PCI DSS) has been a critical framework for protecting cardholder data for the last two decades. It’s also presented a major — and gradually rising — compliance challenge for organizations that handle cardholder data. That challenge is set to ramp up significantly in the coming months, as security standards become even more stringent with PCI DSS 4.0 updates taking full effect in March 2025.

PCI DSS (Payment Card Industry Data Security Standard) v4.0.1 is designed to protect cardholder data and secure payment environments. Compliance with PCI DSS is critical for any organization that stores, processes, or transmits payment card information. The framework helps prevent fraud, data breaches, and financial losses associated with cyber threats targeting payment systems.
