AI has introduced a new class of network traffic. Prompts, file uploads, model calls, and agent actions carrying sensitive business context now traverse the network as organizations race to adopt AI and achieve their business goals. Traditional firewalls were never built to understand these connections, AI activity often looks like ordinary web traffic, leaving the firewall unable to determine whether a prompt contains sensitive data, an agent is calling a tool it should never access, or an application’s AI model is subjected to a malicious prompt. These challenges demand comprehensive protection, which is why Check Point created the AI Defense […]

As part of Check Point’s Frontier AI Readiness Program, we are releasing a jumbo hotfix with security and hardening fixes for our firewall and management products. This update includes a number of security hardening improvements and fixes, the most significant of which are outlined below. During a routine BLAST review, we discovered a few vulnerabilities. Following a thorough analysis, we identified one of those in the wild, affecting a handful of customers. This only affects a very specific configuration — when Management is exposed directly to the internet without IP restrictions. All affected customers have been notified. All Smart-1 Cloud […]

The post Security Advisory – Action Required – July 2026 Security Update appeared first on Check Point Blog.

Check Point Research has identified active exploitation of CVE-2026-50751, a critical authentication bypass vulnerability affecting Check Point Remote Access VPN and Mobile Access deployments configured to use the deprecated IKEv1 key exchange protocol. By exploiting a logic flaw in certificate validation, an attacker can establish a VPN session without possession of a valid password, effectively bypassing authentication requirements. Additional post-authentication activity is required to access internal resources or escalate privileges. To date, the observed exploitation has been limited to a few dozen targeted organizations globally. One case involved confirmed post-compromise activity associated with Qilin ransomware affiliate. Customers using IKEv1 key […]

On May 22, 2026, Dutch financial-crime investigators walked into data centers in Dronten and Schiphol-Rijk and seized approximately 800 servers. The target was WorkTitans B.V., a hosting provider that, on the surface, looked like any other internet infrastructure company. What investigators uncovered, however, was something far more significant: a ghost operation built on sanctioned infrastructure, quietly serving as the backbone for some of Iran’s most active cyber espionage campaigns. The story starts a year earlier. In May 2025, the European Union sanctioned Stark Industries, an internet service provider linked to Russian information-warfare operations. Rather than shutting down, the people behind […]

At Check Point we don’t wait for threats to evolve; we evolve ahead of them. This is why we’ve been running our Frontier AI Models Readiness Program: a proactive, structured initiative designed to ensure that our products remain resilient as AI models grow increasingly capable of understanding complex software systems and assisting adversaries in attacking them. As part of this program, we conducted large-scale AI-driven code scanning across our products, performed extensive security reviews, hardened components where needed, refined our time-to-patch procedures, and accelerated our protection development processes to meet the pace of emerging AI-driven threats. Today’s Jumbo Security Release […]

Networks used to be simple. A perimeter. A data center. A set of rules a single engineer could hold in their head. That world is long gone. Every wave of enterprise transformation – cloud migration, M&A, hybrid multi-cloud, IoT, remote work – added another layer of complexity. Each with its own topology, traffic patterns, and security assumptions. The complexity grew exponentially. And security followed, manually – more policies to author, more configurations to validate, more vendors to manage. The part that doesn’t show up in vendor presentations is that modern network security runs on institutional know-how. It lives in the […]
