EventSentry v6: Azure Logs, HEC, Sigma, Log Signing & More

Even though the shift to the cloud has slowed recently as many businesses are moving certain workloads back on-premise, Microsoft Exchange remains one cloud-based service that most organizations continue to embrace – despite its frequent outages.

AppGuard Critiques AI Hyped Defenses; Expands its Insider Release for its Next-Generation Platform

A new Top 10 Cybersecurity Innovators profile by AppGuard has been released, spotlighting growing concerns over AI-enhanced malware. AI makes malware even more difficult to detect. Worse, they use AI to assess, adapt, and move faster than any cyber stack can keep up.

LLM Security Checklist: Essential Steps for Identifying and Blocking Jailbreak Attempts

If your organization uses a private large language model (LLM), then it’s time to start thinking about countermeasures for jailbreaking. A jailbroken LLM can lead to leaked information, compromised devices, or even a large-scale data breach. Even more troubling: Jailbreaking LLMs is often as simple as feeding them a series of clever prompts. If your customers can access your LLM, your potential risk is even higher.
