Most €10m–€100m organizations are bleeding capital on fragmented tools, alert fatigue, and bloated security headcount, yet they are still getting breached. Today, the new era of THREAT-WATCH is live. We have evolved into a complete, full-spectrum MSSP. We don't just monitor your SOC or send you alerts. We replace your entire cybersecurity department, minus the CISO. By combining advanced AI architecture with Xcitium's elite human threat hunters, we deliver enterprise-grade protection without the enterprise payroll. ✔ 24/7 Monitoring & Active Incident Response ✔ Zero-Trust Endpoint Protection (Powered by Xcitium) ✔ Full ISO 27001 & NIS2 Readiness ✔ Secure by design, backed by a $1 Million Ransomware Breach Warranty Enterprise security, without the enterprise team.

Exploit-DB is down. After thorough research it seems that Exploit-DB has been down for almost 24 hours now both in its RSS feed and the website. If you are trying to access Exploit-DB right now, you are likely seeing 502 errors and timeouts. The web interface is struggling. In our industry, downtime isn't just an inconvenience; it's a blind spot. When the primary source goes dark, where do you get your data? This is exactly why I built Threat-Watch with a "Zero-Single-Point-of-Failure" architecture. While the main Exploit-DB site is down, Threat-Watch users are still receiving real-time exploit feeds. #CyberSecurity #ThreatIntel #ExploitDB #InfoSec

Registering with the NCSA got you on a list. It didn't get you ready for an inspection. Law 5160/2024 set a Greek national registration deadline of September 30, 2025. Same directive, same legal powers, different country currently using them at scale. Germany's BSI is auditing roughly 29,000 registered entities right now under NIS2, requesting risk-assessment reports and running on-site inspections without warning. Greece's NCSA holds the identical authority under its own transposition. There is no legal reason to assume it stays dormant here just because your company hasn't been audited yet. Most companies that have a vendor assume "we're covered" means the paperwork exists somewhere. It usually means it existed once, at onboarding, and hasn't been touched since. Curious how many companies here have actually took measures for NIS2 with their vendors. #NIS2 #cybersecurity #greece
