Detect. Disrupt. Defeat #Ransomware.

6,635 confirmed #ransomware attacks. One year.

That’s how active the ransomware ecosystem was in 2025 - and attackers didn’t just scale activity. They evolved.

353 unique ransomware variants were detected, with new strains emerging almost daily.

The ransom isn't the biggest cost. Downtime is. #Ransomware risk starts with business impact—not the demand. Read more. https://t.co/oOTQct6RHG

“Don’t get breached” isn’t a strategy. It’s a wish.

Gary Hayslip explains why real #cybersecurity is measured in resilience - how you operate, recover, and adapt.

Financial services can’t prevention-their-way out of #ransomware.

Leaders from Virgin Money, SoftBank & Barclays break down what resilience requires: identity, recovery speed, third-party risk + #AI-powered threats.

More threat data than ever. Same amount of time to act on it.
25 years after 9/11, that's the new intelligence failure. #cybersecurity https://t.co/OXS9ySnGNG

Your #cyber insurance renewal is now an audit. The controls you attest to today could determine whether your claim gets paid tomorrow. #ransomware https://t.co/6BCnIy5MsA

[HalcyonAI @HalcyonAi]

Your ransomware tabletop has one major flaw: nothing is actually on fire.

A real attack forces high-stakes decisions with incomplete information—and that’s where recovery starts to unravel.

“This is not a theoretical risk.”

🏥 A #ransomware attack on one hospital can put an entire region at risk.

When ERs go offline, patients are diverted — & for a stroke or heart attack, every minute matters.

@MayoClinic’s Heather Costa + Cynthia Kaiser explain the ripple effect. 👉 https://t.co/Yilbzk0f5d

You can pass every audit and still lose to #ransomware.

Compliance sets the baseline. Resilience determines what happens when prevention fails.

Ransomware doesn't wait for you to go home. The early attack chain runs 9-to-5 — 69% of activity we tracked hit during business hours, hiding in plain sight.

Encryption? That waits till you're gone.

#Qilin is back in the headlines after leaking sensitive files allegedly stolen from the ATF.

@CNN turned to Halcyon research for context on the #ransomware group behind the attack. #Cybersecurity https://t.co/7Zuf6tDWwa

Most companies inherit their security stack. Milacron refused to take on someone else's #ransomware risk.

Full deployment. Zero disruption. Resilience from day one.

#Ransomware recovery isn't a weekend project. It's a 22-day war - 38 for enterprises. And that's with tested backups. See why. https://t.co/94g0GscQxp
