Coop – Isolated VM Environments for Running Claude Code and Codex
Trail of Bits releases Coop, running Claude Code and OpenAI Codex agents inside isolated virtual machines for safer agentic coding.
Coop, published on GitHub by security firm Trail of Bits, provides isolated VM environments for executing AI coding agents such as Claude Code and Codex. Isolation contains the filesystem and network side effects of autonomous agent actions, reducing risk from unsupervised tool use. The project drew 61 points and 16 comments on Hacker News.

How AI and cybersecurity are reshaping ServiceNow
Analysis argues ServiceNow's $7.75B Armis acquisition and AI-driven consumption pricing are reshaping its ITSM platform amid SaaS market anxiety.
CSO Online examines how AI agents, vibe-coding fears, and a reported 30% share price drop are pressuring ITSM leader ServiceNow, and how the company is pivoting toward consumption-based revenue and cybersecurity. The piece highlights ServiceNow's $7.75 billion cash acquisition of Armis, priced at roughly 23 times the vendor's $340 million annual revenue, as a strategic move to supercharge ITSM workflows with accurate device inventory and orchestration rather than to sell a standalone security product. Experts note this ends Armis's vendor-neutral position, introduces the CISO as a new buyer, and will likely lead to aggressive Armis bundling at contract renewals.

VMs won't contain cyber-capable agents
Trail of Bits argues virtual machines alone cannot contain cyber-capable AI agents, challenging VM sandboxing as adequate agent isolation.
Trail of Bits published an analysis arguing that virtual machines will not adequately contain cyber-capable AI agents. The post challenges the assumption that VM-based isolation is sufficient for agents with offensive cyber capabilities, with implications for how autonomous agents should be sandboxed. The available text contains no further technical details.

Top 10 Best Server Security Solutions in 2026
Cyber Security News ranks 2026 server security platforms, favoring Trend Micro for hybrid estates, CrowdStrike for detection, Defender for Azure economics.
Cyber Security News published an editorial ranking of ten server security platforms for 2026, favoring Trend Micro for hybrid estates, CrowdStrike for detection quality, and Microsoft Defender for Servers for Azure-centric economics. The guide stresses that server security licensing differs (per server, per core, or per cloud-hour) and flags hypervisor protection as a commonly missed coverage gap.

12 Best Server Security Solutions Compared (2026): Features & Pricing
GBHackers ranks 12 server security solutions for 2026, naming CrowdStrike and SentinelOne as server EDR leaders and Trend Micro Deep Security top for virtual patching.
The guide scores 12 server security platforms across five weighted criteria, with detection and response depth and Linux parity weighted 25% each. CrowdStrike and SentinelOne lead server EDR, Trend Micro Deep Security is highlighted for virtual patching of unpatchable estates, and Microsoft Defender for Servers is noted for Azure and hybrid economics. It is an editorial assessment comparing features and pricing models rather than a lab test.

F5 speeds up virtual patching to counter AI-driven threats
F5 added anomaly detection and agentic threat intelligence to its AI-powered WAF, enabling virtual patch enforcement against exploits within minutes.
F5 announced enhancements to F5 WAF for Distributed Cloud, adding anomaly detection that builds per-application traffic baselines and agentic threat intelligence built on technology from the Fletch acquisition. The AI-powered WAF scores each request in real time with a neural network risk engine, and internal testing claims 98% threat detection efficacy with false positives reduced to 1%. Automated virtual patching via Distributed Cloud Web App Scanning extends to F5 WAF for BIG-IP, letting teams block actively exploited vulnerabilities at the request level in minutes; agentic features are rolling out over coming months.
