Why SIEM Rules Fail and How to Fix Them: Insights from 160 Million Attack Simulations

Aug 25, 2025 Network Security / Threat Detection
Security Information and Event Management (SIEM) systems act as the primary tools for detecting suspicious activity in enterprise networks, helping organizations identify and respond to potential attacks in real time. However, the new Picus Blue Report 2025 , based on over 160 million real-world attack simulations , revealed that organizations are only detecting 1 out of 7 simulated attacks , showing a critical gap in threat detection and response. While many organizations believe they're doing everything they can to detect adversary actions, the reality is that a large number of threats are slipping through their defenses unnoticed, leaving their networks far too vulnerable to compromise. This gap in detection creates a false sense of security when attackers have already accessed your sensitive systems, escalated their privileges, or are actively exfiltrating your valuable data. Which begs the question: why, after all this time, money, and attention, are these systems still ...

CISO's Expert Guide To CTEM And Why It Matters

Feb 17, 2025 Enterprise Security / Attack Simulation
Cyber threats evolve—has your defense strategy kept up? A new free guide available here explains why Continuous Threat Exposure Management (CTEM) is the smart approach for proactive cybersecurity. This concise report makes a clear business case for why CTEM's comprehensive approach is the best overall strategy for shoring up a business's cyber defenses in the face of evolving attacks. It also presents a real-world scenario that illustrates how the business would fare against a formjacking attack under three security frameworks - Vulnerability Management (VM), Attack Surface Management (ASM), and CTEM. With VM, the attack might go unnoticed for weeks. With CTEM, simulated attacks detect and neutralize it before it starts. Reassuringly, it also explains that CTEM builds on a business's current VM and ASM solutions rather than requiring them to jettison anything they currently use. But first— What is CTEM? In response to increasingly sophisticated cyberattacks, Gartner introduced ...

CTEM 101 - Go Beyond Vulnerability Management with Continuous Threat Exposure Management

Mar 12, 2024 CTEM / Vulnerability Management
In a world of ever-expanding jargon, adding another FLA (Four-Letter Acronym) to your glossary might seem like the last thing you'd want to do. But if you are looking for ways to continuously reduce risk across your environment while making significant and consistent improvements to security posture, in our opinion, you probably want to consider establishing a  Continuous Threat Exposure Management (CTEM)  program.  CTEM is an approach to cyber risk management that combines attack simulation, risk prioritization, and remediation guidance in one coordinated process. The term Continuous Threat Exposure Management first appeared in the Gartner ® report, Implement a Continuous Threat Exposure Management Program (CTEM) (Gartner, 21 July 2022,). Since then, we have seen that organizations across the globe are seeing the benefits of this integrated, continual approach.
