Five years ago, enterprise ransomware risk was mostly a perimeter problem. Today it’s an identity problem, a visibility problem, and a cloud configuration problem, all at once. Hybrid work and cloud adoption didn’t just shift where people work. They fundamentally changed where ransomware attacks begin, how far they reach, and how long they go undetected.

AI-powered attackers are faster and more systematic than ever. But they still trust what they see. Deception technology controls what they see. 87% of security leaders say AI-related vulnerabilities grew faster than any other risk in 2025 44% year-over-year rise in exploitation of public-facing applications in 2025 300K+ AI platform credentials exposed via infostealer malware on dark web in 2025.

Deception and Claude Mythos is no longer just a cybersecurity conversation. It’s a paradigm change in how organizations need to consider cyber resilience in the era of AI. Enterprises are facing a new threat landscape in which attackers can find exploits quicker, conduct enterprise-wide reconnaissance with low-level automation, and exploit enterprise assets with unprecedented accuracy on an enterprise-wide scale.

With the rise of data breaches and hacking attempts, a strong cybersecurity posture is the most significant need today. Given the scale of cybercrime growth, you need to carefully consider several key factors that will ultimately impact the cybersecurity solution you pick. Businesses have realized the value of their data; now they must invest in tools to easily detect and respond to security issues.

Security teams that deploy insider threat monitoring for the first time rarely catch what they went looking for. They wanted a bad actor. What they found was a ground-truth map of how their organization actually handles sensitive data, and in most cases, that map looked nothing like the policies on paper. That gap, between documented security controls and real-world data behavior, is precisely what insider threat monitoring exposes.

CI/CD pipeline security is not a single tool decision. The pipeline spans source code, build systems, container registries, infrastructure configs, and production workloads. Each stage carries different risks and needs different controls. This guide covers the full stack of ci/cd pipeline security tools, the industry standards that govern them, and the CI/CD security best practices that make them work in production.

Most security teams did not architect their hybrid cloud environment. It grew. A legacy ERP that finance refused to migrate off-premises, a Kubernetes cluster a product team spun up in GCP without telling IT, three SaaS applications that became mission-critical before anyone ran a security assessment on them, and a VPN that was supposed to be temporary in 2020 and is still running.

Remote Code Execution (RCE) is one of the dangerous vulnerabilities when it comes to cyberattacks and safeguarding against them is critical. In real-world environments, attackers keep looking for unpatched software and misconfigurations to gain an opportunity for remote code execution. Once code execution is achieved, a simple technical glitch becomes an active intrusion. Proactive detection is a crucial part of any RCE defense strategy.

Sybil attacks are well documented in academic research. In practice, most organizations discover them too late, after the fake identities have already accumulated enough network influence to do real damage. The attack does not announce itself. It looks like growth. You see more nodes. More accounts. More participation. All of it is controlled by one attacker running a coordinated identity flood.

Traditional detection methods are struggling to keep up with modern threats. What if you could turn attackers into your strongest signal? In this session, our Sales Engineer Jim breaks down how deception technology is transforming cybersecurity by: Delivering high-fidelity alerts with minimal noise Adapting dynamically to attacker behavior Extending protection to IoT and non-standard devices Scaling seamlessly across enterprise environments.

CVE-2025-59287 turns WSUS (Windows Server Update Services) into a high-value attack surface—and attackers are already abusing it. In this video, we break down how CVE-2025-59287 is exploited, what defenders should look for, and how to mitigate and detect attacks before damage spreads across your environment. What you’ll learn in this video: How attackers scan exposed WSUS servers on ports 8530 and 8531.

As attack surfaces continue to expand, many security teams are finding that traditional detection methods can’t keep up. In this clip, the discussion centers on why legacy security tools struggle in modern environments — from the growing complexity of networks to the sheer volume of alerts teams are expected to investigate. When alerts are handled manually and without sufficient context, it becomes difficult to understand which threats are most critical and how quickly to respond.

In an age where digital defenses are constantly under attack, it's clear that your Active Directory serves as the battleground for your cybersecurity efforts. With Verizon's 2024 DBIR report highlighting compromised credentials as the most favored attack vector, the importance of fortifying your Active Directory cannot be understated. A breach doesn't just mean inconvenience; it signifies potential catastrophe - crippling system downtimes, critical data breaches, and organizational standstill.
