Security | Threat Detection | Cyberattacks | DevSecOps | Compliance

SIEM-less security may sound like an escape from traditional SIEM complexity and costs, but the underlying capabilities still have to exist somewhere. A SIEM is a multipurpose tool. It brings together cyber and physical security use cases; drives threat detection, investigation, and response (TDIR); serves as a system of record for governance, regulatory, and compliance needs; and supports observability use cases tied to resilience and service degradation. The list goes on.

PHP2Shell is a pair of critical flaws in the PHP interpreter itself, each with a CVSS v4.0 score of 9.2. Both let an unauthenticated attacker run code on a web server with a single crafted web request, or a pair of them, before any application code runs. Because the bug lives in PHP, not in WordPress, Drupal or Magento, every reachable PHP endpoint on an affected server is exposed, including login pages, static forms, and health checks. Every PHP release from the last decade is affected (back to 5.4).

Effective security operations require more than isolated alerts. Analysts need context from across the environment to understand what happened, assess its significance, and decide what to do next. That is why accessing insights and telemetry from across your networking and security stack is critical to teams using a SIEM tool.

Risk in the agentic enterprise spans people, service accounts, and AI agents. All three act with legitimate credentials, so access controls alone can’t show whether their activity is safe. A behavioral risk framework applies one model to every actor: Verify expected behavior before access goes live, observe activity once it does, analyze behavior for risk and drift, and improve detection coverage over time.

Every Operating System – not even counting the software installed on top of it – has a myriad of configuration settings that affect security. Windows Server alone has 4000+ configurable options, out of which 200+ are important for security & compliance efforts. They include: These settings are at the very core of all of your security & compliance efforts – and they are surprisingly often ignored.

The rules of cyber defense have shifted. Threat actors are increasingly using advanced automation to accelerate reconnaissance, evade static signatures, and orchestrate rapid intrusions across critical infrastructure, software supply chains, and insider pathways. This has created a critical velocity gap: when adversaries compress attack timelines from days to minutes and defenders rely on manual triage across fragmented legacy tools, the defense falls behind.

The future of policing depends on more than changing force structures or investing in AI. It depends on making data work across boundaries. Policing is being asked to change at pace.

A security leader finishes a pitch to the board about an agentic SOC that pairs AI agents with analysts to address the coverage gap. A hand goes up. “So, the AI decides who’s a threat?” It’s a fair question. It’s also the wrong one, built on a myth that’s common enough to stall adoption on its own.

CISOs need an agentic SOC strategy because traditional staffing models can’t scale to match machine-speed threats, a global talent shortage, and rising alert volume. An agentic SOC pairs AI agents that collect evidence and investigate at machine speed with analysts who provide judgment, context, and accountability. Exabeam combines Agent Behavior Analytics (ABA), Exabeam Nova AI, and automated investigation to expand coverage and speed response without adding headcount.

Exabeam delivers stronger detection, faster investigations, and more flexible deployment than IBM QRadar and Cortex XSIAM. It combines user and entity behavior analytics (UEBA), Agent Behavior Analytics (ABA), and agentic AI through Exabeam Nova AI to reduce alert noise and automate workflows. With cloud-native capabilities in New-Scale Fusion, Exabeam gives security teams a modern approach to SIEM and security operations.

There is a moment in security operations that has become increasingly familiar: nothing looks obviously wrong. The login is valid. The employee has the right permissions. The AI agent is using credentials it was legitimately given. And yet something has changed. That change is often where the real story begins.

The October 2026 LogRhythm SIEM release modernizes self-hosted security operations with an in-place migration from Elasticsearch to OpenSearch, a next-generation self-service reporting engine, generative AI collectors, and a community Model Context Protocol (MCP) server. The release also includes backend and API updates that improve event drilldown, rule administration, network routing, and telemetry quality while helping organizations maintain control of sensitive security data.

An agentic SOC uses AI-powered investigation, analysis, and automation to gather data, connect activity, and handle repetitive investigative work. Analysts remain in control and focus on judgment, prioritization, and response. This addresses the need for machine-speed security operations as AI agents gain autonomy and Tier 1 access to systems. Spend five minutes watching a security analyst at work and the “AI will replace analysts” headline starts to sound out of touch.
