Most vulnerability platforms give you more findings. Sirius Scan was built to give operators more clarity. Open-source. Operator-first. Built for real security teams. sirius.opensecurity.com/

Most vulnerability management programs don’t fail quietly— At @BlackHatEvents USA, learn from @0sm0s1z how to assess real risk like an operator: identify true attack paths and prioritize what actually matters. Early reg ends May 22: bit.ly/3PPte7u

Adversaries are moving faster. Detection windows are shrinking, and vulnerability management must become operational. At @BlackHatEvents, I’ll be teaching a course on operationalizing vulnerability management from the operator’s perspective. Join me: bit.ly/3PPte7u

💼 Cybercrime is business — built on risk vs. reward. Many ransomware operators make millions. The lavish lifestyles you see online — Lamborghinis, exotic pets — are very real. But every dollar comes with exposure.

💰 That Lamborghini driver may never leave jurisdictions that protect them. One mistake — like traveling to Poland — can mean arrest. (One REvil member tied to the Colonial Pipeline attack learned that firsthand when Interpol apprehended him.)

📊 Cybercrime isn’t random. It's organized, calculated, and financially driven. The more we study their business model, the better we can defend ours. Speak with one of our experts here: opensecurity.com/contact/ Check out vulnerability scanner here: opensecurity.com/resources/t…

Traditional tools like Nexpose, Rapid7, Tenable, and Qualys have a major head start. Decades of module development = deeply entrenched IP. But what if we started over—smarter? With Vulnerability GPT, we built a new foundation:

Vulnerability Management is a Mess. In most orgs, it’s disorganized, reactive, and overly complex. Why? Because no one’s come in and said: ✅ “Here’s how you align with industry leaders.” ✅ “Here’s where you’re falling behind.” ✅ “Here’s a clear path forward.”

Instead, teams are left guessing — chasing scanner results, patching without priority, and playing guessing games with risks. It’s time for a reset. We need frameworks. We need real-world benchmarking. We need operational clarity — not just another tool.
